What if Deku became vessel of isshiki otsutsuki

The wind howled across the rooftop, a hollow, lonely sound that seemed to carry all the world’s indifference.

 

Izuku Midoriya stood frozen, his emerald eyes wide and trembling. The air tasted of ozone and city smog, but all he could focus on was the man standing before him. Or rather, the man who had just stood before him. Only moments ago, the towering, golden-haired titan known as All Might—the Symbol of Peace, the invincible god of hero society—had been standing there. Now, as the thick veil of steam dissipated into the afternoon sky, there was only a skeletal, emaciated man in baggy clothes, coughing up blood into a handkerchief.

 

Izuku’s mind was a whirlwind of confusion, denial, and terror. He had clung to the hero’s leg, soared through the sky, and finally asked the question that had haunted him since he was four years old. The question that defined his miserable, Quirkless existence.

 

Can someone without a Quirk be like you?

 

The skeletal man wiped his mouth, his deep-sunken eyes carrying a heavy, exhausted weight. "Pros are always risking their lives," All Might said, his voice stripped of all its booming, theatrical bravado. It was a raspy, quiet sound. Real. Too real. "Some villains simply can't be beaten without powers. So no, I honestly don't think you can become a hero without a Quirk."

 

The words didn't just hit Izuku; they hollowed him out. It felt as though a physical hand had reached into his chest and crushed his lungs. He couldn't breathe. The world tilted slightly on its axis.

 

"If you want to help people," All Might continued, turning his back toward the roof's access door, "there are other ways. You could become a police officer. They get a lot of crap because the villains are delivered to their doorstep, but it's a fine profession. It's not bad to have dreams, young man. Just... make sure they're realistic."

 

The door opened with a metallic creak. It closed with a heavy thud.

 

Silence descended upon the rooftop.

 

Izuku stood there for what felt like an eternity. The notebook in his hand—Hero Analysis for the Future No. 13—felt like a block of lead. The edges were still singed and damp from where Katsuki Bakugo had blown it up and tossed it into the koi pond earlier that day.

 

“If you want a Quirk so badly, take a swan dive off the roof and pray you’re born with one in your next life!”

 

Katsuki’s cruel laughter echoed in his ears, blending with the hollow ringing left behind by All Might’s devastating verdict. His mother’s tearful apologies, the doctor’s apathetic diagnosis, the years of mocking laughter from his classmates—it all culminated here, on a nameless rooftop, delivered by the very man Izuku had worshipped.

 

Realistic, Izuku thought, his lower lip trembling as the first tear broke free, carving a warm path down his freckled cheek. Realistic.

 

His knees buckled. He collapsed onto the rough concrete, his yellow backpack sliding off his shoulder. He didn't scream. He didn't sob out loud. The despair was too profound, too absolute for something as simple as noise. He simply folded in on himself, clutching his knees to his chest, as the last embers of his childhood dream flickered, choked on reality, and died.

 

 

 

Hours passed. The sky above Musutafu transitioned from a vibrant, hopeful blue to a bruised violet, and finally, to the suffocating black of night.

 

Izuku walked through the city streets like a ghost. His feet dragged, the rubber of his iconic red shoes scuffing against the pavement. He didn't know where he was going. He didn't want to go home. He couldn't face his mother's worried, pitying eyes tonight. He couldn't stomach the shrine of All Might merchandise that decorated his bedroom—the posters, the action figures, the bedsheets. What had once been a source of endless inspiration now felt like a cruel, mocking joke.

 

The city around him was alive, buzzing with neon lights, holographic advertisements for Hero agencies, and the distant wail of police sirens. Everyone had a place here. Everyone had a power, a purpose, a mutation that made them part of the grand tapestry of superhuman society.

 

Except for him. He was a baseline. A genetic dead end. An anomaly of the past walking through the world of the future.

 

To avoid the crowds and the flashing screens broadcasting heroic deeds, Izuku veered off the main road. He wandered into an older, dilapidated industrial district on the edge of the city. The streetlights here were sparse, flickering with dying bulbs. The buildings were abandoned warehouses, their walls choked with ivy and aggressive, territorial graffiti.

 

He turned down a particularly narrow, shadowy alleyway. The air here was damp, smelling of rusted metal and wet asphalt. It was quiet. The oppressive noise of the hero-obsessed society faded away, leaving only the sound of his own shallow breathing.

 

Maybe Kacchan was right, Izuku thought, staring blankly at the wet pavement. His mind went to dark, terrifying places. If I'm just a burden... if I can't do anything... what's the point?

 

He stopped in the middle of the alley, closing his eyes, letting the darkness wrap around him. He felt so unbelievably empty. A hollow vessel.

 

Then, the air pressure dropped.

 

It was instantaneous. One second, the alley was stagnant and cold; the next, the air became thick, heavy, and suffocatingly hot. Izuku gasped, his eyes flying open as a high-pitched, agonizing whine filled his ears. It didn't sound like a machine. It sounded like the very fabric of the air was screaming in pain.

 

What is that? A villain? Izuku's instincts flared, but his body remained frozen.

 

Ten feet in front of him, the darkness began to warp. Space itself seemed to ripple, like a stone dropped into a calm pond, but the ripples were jagged, angular, glowing with a sickly, malevolent crimson light. Black lightning, completely devoid of sound, arched out from the anomaly, striking the brick walls and disintegrating the stone upon impact.

 

Izuku scrambled backward, tripping over his own feet and landing hard on his tailbone. "W-What..."

 

With a sound like shattering glass, reality tore open.

 

A fissure, jagged and bleeding with cosmic energy, ripped through the alleyway. It was a portal, but not like any teleportation Quirk Izuku had ever analyzed. This felt wrong. It felt profane. Looking into the rift made Izuku's eyes water; it was a window into a void of swirling, chaotic dimensions, a place where the laws of physics went to die.

 

From the swirling vortex of the portal, a figure was violently ejected.

 

The entity crashed onto the pavement with a sickening crunch, sliding several feet before coming to a halt near the rusted dumpster. The portal instantly snapped shut behind him, leaving the alley bathed in the dim, flickering light of a single streetlamp.

 

Izuku held his breath, his heart hammering against his ribs like a trapped bird. Slowly, tentatively, he pushed himself up onto his hands and knees.

 

The figure on the ground was a man—or at least, humanoid. But the damage he had sustained was catastrophic.

 

He was incredibly tall, clad in bizarre, regal white robes lined with black magatama patterns, though the garments were scorched and shredded. His skin was deathly pale, stark white, contrasting with the horrific amounts of dark, purplish blood pooling beneath him. Half of the man's lower torso and his left leg appeared to have been obliterated by some unimaginable force, cauterized and still smoking.

 

But it was the man's head that struck true terror into Izuku's soul.

 

From the left side of his skull, a jagged, broken horn protruded, snapped off at the base. His hair was stark white. As the man gasped, a wet, rattling sound, his eyes shot open.

 

Izuku gasped. The man's left eye was a milky, featureless white, pulsing with prominent veins around the temple. But his right eye was a mesmerizing, terrifying golden wheel, resembling an eight-spoked Dharma wheel, glowing with an inner, predatory light.

 

What is this? Izuku thought, trembling violently. A Nomu? A high-tier villain? He's dying... I have to call an ambulance!

 

Despite his despair, despite the crushing revelation that he could never be a hero, Izuku's legs moved on their own. He scrambled toward the dying alien.

 

"H-Hey!" Izuku stammered, his voice cracking as he reached for his flip-phone. "Hold on! I'm calling for help! Stay with me!"

 

The dying being—Isshiki Ōtsutsuki—coughed, a violent spasm that sent a spray of dark blood onto the pavement.

 

Isshiki's mind was fading rapidly. The battle had been a disaster. The vessel, Kawaki, had evaded him. Naruto Uzumaki’s suicidal Baryon Mode had shaved his lifespan down to less than a handful of minutes. In a final, desperate act of survival as his body began to crumble into dust, Isshiki had poured the very last dregs of his chakra into his ocular jutsu, tearing a hole not just through space, but through the dimensional boundaries of the multiverse itself.

 

He had leaped blindly, hoping to find a world with chakra to consume, a vessel to implant his Karma into before his soul was extinguished forever.

 

He had landed here. In this filthy, primitive alleyway.

 

Isshiki forced his Byakugan to activate, scanning his surroundings. The ambient energy of this world was... strange. There was no natural energy. No chakra in the earth, no chakra in the air.

 

He turned his gaze to the green-haired boy hovering over him, clutching a primitive communication device.

 

Isshiki scanned the boy's internal structure, and his golden eye widened in absolute disbelief.

 

No chakra coils, Isshiki realized, his mind racing as the edges of his vision began to darken. None at all. The humans of this dimension... they possess a different biological mutation. A genetic anomaly located in their DNA.

 

He looked deeper into the boy, analyzing his genetic code.

 

Wait.

 

The boy lacked the mutation. He lacked chakra. He lacked everything.

 

In Isshiki’s eyes, Izuku Midoriya was a biological void. A completely blank slate. In all his millennia of conquering planets and harvesting Chakra Fruits, Isshiki had never encountered a creature so utterly devoid of internal resistance. A normal human body would fight the Karma, risking incompatibility and death. But this boy? There was nothing inside him to fight back. He was an empty cup, waiting to be filled.

 

Furthermore, Isshiki’s ocular prowess allowed him to read the spiritual pressure of a creature. The boy's spirit was fractured. Shattered. The will to resist was non-existent. He was radiating a profound, absolute despair.

 

Perfect, Isshiki thought, a cruel, bloody smirk twisting his pale lips. Utterly perfect. The universe bends to my survival.

 

"H-Hang on!" Izuku cried, dialing the emergency number. "They're on their way! You're losing a lot of blood, sir, I don't know what your Quirk is but—"

 

Izuku never finished the sentence.

 

With blinding, impossible speed, Isshiki’s remaining arm shot out. His pale, bloodstained hand wrapped around Izuku’s throat like a vice of cold steel.

 

Izuku choked, dropping his phone as he was yanked forward, his face brought within inches of the alien’s terrifying visage. The grip was immovable, crushing his windpipe. Panic exploded in Izuku’s chest. He clawed at the pale hand, kicking his legs, but Isshiki, even on the brink of death, possessed physical strength that eclipsed anything Izuku had ever felt—even All Might.

 

"Help..." Izuku wheezed, his vision blurring.

 

Isshiki stared into Izuku’s terrified, tear-filled green eyes. The alien’s golden right eye spun slowly, exuding an aura of immense, crushing gravity.

 

"You weep," Isshiki spoke, his voice a deep, reverberating baritone that didn't just hit Izuku's ears, but echoed directly inside his skull. It sounded ancient, arrogant, and dripping with malice. "Your soul is hollow. You desire power, boy? You desire to be a savior of these inferior creatures?"

 

Izuku couldn't speak. He could only thrash, his oxygen depleting. The sheer killing intent radiating from the broken man was paralyzing. It was a predator looking at an insect.

 

"My time in this vessel is at an end," Isshiki rasped, his skin beginning to flake away into grey ash. "But an Ōtsutsuki does not perish. We transcend. You are empty. A pathetic, powerless husk."

 

Isshiki’s grip shifted. He released Izuku's throat, but before the boy could retreat, the alien’s hand clamped down violently onto Izuku’s left palm.

 

"Therefore, you shall bear my weight. Rejoice, boy. Your empty existence now serves the will of a god."

 

"No! Let go!" Izuku screamed, pulling with all his might, but Isshiki's grip was fused to him.

 

Isshiki channeled the very last spark of his life force. Karma.

 

Izuku let out a bloodcurdling scream as an agony unlike anything he had ever experienced erupted in his left hand. It felt as though a red-hot iron spike was being driven through his palm, straight into his bone marrow.

 

He watched in absolute, paralyzed horror as a small, pitch-black diamond shape burned itself into the center of his palm. But it didn't stop there. The diamond pulsed like a living heartbeat. Jagged, geometric black lines shot out from the diamond, slithering up Izuku’s wrist and forearm like ink injected into his veins.

 

It burns! It burns! Izuku shrieked, his voice tearing his vocal cords.

 

It wasn't just physical pain. It was a profound, deeply violating sensation. He could feel his very cells screaming, his DNA being forcibly unraveled, read, and overwritten by an invasive, alien data stream. It was a digital download of a soul being burned into his biological hard drive. The sheer volume of the data—millennia of combat, cosmic knowledge, and god-like chakra—was far too massive for his mortal mind to process.

 

Isshiki’s body was rapidly turning to ash, the wind beginning to scatter his remains.

 

As his physical form disintegrated, Isshiki leaned in, his golden eye fading into dust, his final words echoing in the physical world and inside Izuku's mind simultaneously.

 

"Do not disappoint me, my vessel. Survive until my resurrection."

 

With those words, Isshiki Ōtsutsuki crumbled into a pile of grey ash, leaving behind only his shredded, bloodstained robe.

 

The connection severed, Izuku flew backward, crashing into the brick wall of the alley. He curled into a fetal position, clutching his left arm to his chest. The black, geometric lines were glowing with a sinister, faint red light, pulsing in time with his frantic heartbeat.

 

His brain felt like it was splitting open. Flashes of imagery that did not belong to him flooded his consciousness.

 

A massive, roaring beast with ten tails... A towering tree piercing the clouds, absorbing the life of a planet... A golden fruit dripping with power... A blue-eyed boy with golden hair, radiating defiant energy...

 

"Make it stop..." Izuku sobbed, slamming his head back against the brick wall. "Make it stop, make it stop, please!"

 

The pain reached a crescendo, a blinding, white-hot flash of agony that overloaded his nervous system. The black lines slowly receded, pulling back down his forearm, past his wrist, until they consolidated once more into the small, jet-black diamond in the center of his palm.

 

Izuku's eyes rolled back into his head, and he mercifully plummeted into the dark, silent abyss of unconsciousness.

 

 

 

Drip. Drip. Drip.

 

The rhythmic sound of condensation falling from a rusty fire escape onto a hollow metal trash can was the first thing to register in his mind.

 

Izuku groaned, his body feeling as though he had been run over by a freight train. Every muscle ached, and his head throbbed with a dull, persistent migraine. The pavement beneath him was freezing cold.

 

Slowly, painfully, he forced his eyes open.

 

The alleyway was silent. The faint amber glow of the streetlamp illuminated the damp brick walls. It was deep into the night; the distant sounds of the city had quieted down to a low hum.

 

Izuku sat up, rubbing his forehead. He felt incredibly dizzy.

 

What happened? he thought, his memory fragmented and hazy. I talked to All Might... he said no... I walked home... and then...

 

The memories hit him with the force of a physical blow. The jagged portal. The dying man with the broken horn. The golden eye. The paralyzing grip.

 

Izuku scrambled away from where he had been lying, his back hitting the wall. He looked frantically at the ground. There was no body. There was no blood. But there, lying on the wet pavement, was a pile of grey ash and the scorched, shredded remains of a white robe with black magatama patterns.

 

It wasn't a dream, Izuku realized, his breath hitching in his throat. It was real.

 

A sudden, terrifying thought pierced his mind. He looked down at his left hand.

 

He was wearing his yellow fingerless gloves, but he could feel a strange, localized heat emanating from his palm. With trembling, sweaty fingers, Izuku peeled the glove off.

 

He stopped breathing.

 

There, stamped dead in the center of his palm, was a perfectly symmetrical, pitch-black diamond. It looked like a tattoo, but the edges of the ink seemed to shift ever so slightly beneath his skin, as if it were alive. As he stared at it, a cold, dark chill washed over his body, starting from his hand and settling deep into his chest.

 

He tried to rub it off, scrubbing at his palm with his thumb, but the mark was indelible. It was a part of him now.

 

Suddenly, an echo—faint, but unmistakable—reverberated in the darkest corner of his mind.

 

"You are empty. A pathetic, powerless husk."

 

Izuku gasped, grabbing his head, looking wildly around the empty alley. "Who's there?!" he shouted, his voice echoing off the brick walls.

 

No one answered. The alley remained silent.

 

But Izuku knew he wasn't alone. He could feel it. A foreign presence, dormant but undeniably alive, coiled tightly within his very cells. It felt cold. It felt ancient. And it felt immensely, terrifyingly powerful.

 

Izuku stared at the black diamond, the words of the alien echoing over and over in his mind.

 

Your empty existence now serves the will of a god.

 

Earlier that day, Izuku Midoriya had lost his dream. He had accepted that he was a powerless, empty vessel in a world of supermen. But as he sat in the cold, damp alleyway, looking at the mark that bound him to an alien god, a terrifying realization dawned on him.

 

He wasn't empty anymore.

 

Something had filled the void. And whatever it was, it was far, far worse than being Quirkless.

 

Izuku pulled his glove back on, hiding the mark, hiding his new, cursed reality. He picked up his yellow backpack, his legs shaking as he stood. He had to go home. He had to pretend everything was normal.

 

But as he walked out of the alley and back into the neon-lit streets of Musutafu, a singular, cold thought pushed its way to the forefront of his mind—a thought that felt disturbingly detached, utterly lacking the warmth and anxiety that usually defined Izuku Midoriya.

 

The world is so fragile, the thought whispered.

 

Izuku shuddered, pulling his jacket tight against the night wind, unaware that the countdown to the end of the world had just begun, ticking away in the palm of his hand.

 

 

 

The sunlight filtering through the blinds of Izuku Midoriya’s bedroom felt unusually sharp.

 

Izuku opened his eyes. He didn’t groan, he didn’t stretch, and he didn’t slowly blink away the sleep. He was simply awake. Instantaneously, sharply awake.

 

He lay in bed, staring up at the ceiling, which was plastered with a mosaic of All Might posters. The Symbol of Peace smiled down at him, frozen in eternal, confident laughter. Yesterday, that smile had been the sun around which Izuku’s universe orbited. Today, it looked like a faded relic of a past life.

 

Izuku sat up, and the first thing he noticed was the profound absence of fatigue. Usually, he woke up sluggish, his body heavy with the chronic lethargy of a teenager who spent too much time hunched over notebooks and crying over impossible dreams. But this morning, a thrumming, electric energy coursed beneath his skin. He felt impossibly light.

 

He looked down at his left hand. The fingerless yellow glove was still on.

 

Taking a deep, shuddering breath, Izuku peeled the fabric back. The pitch-black diamond was still there, sitting dead-center in his palm. It wasn't a hallucination. It wasn't a nightmare. The memory of the dying, pale-skinned man with the broken horn and the terrifying golden eye crashed into his consciousness, as vivid as a photograph.

 

“Your empty existence now serves the will of a god.”

 

Izuku traced his right thumb over the mark. It wasn't raised like a scar or textured like a burn. It was perfectly smooth, seamlessly integrated into his flesh. But it felt warm. A strange, localized fever burned just beneath the surface of the diamond.

 

“Izuku! Breakfast is ready!” Inko Midoriya’s voice called from the kitchen.

 

Izuku flinched, quickly pulling the glove back over his hand. He couldn't tell her. How could he possibly explain this? Hey, Mom, a dying alien from another dimension hijacked my body in an alleyway last night. She would have a heart attack, or worse, have him institutionalized. He had to keep this a secret. He had to figure out what this was, what it was doing to him, and if there was a way to remove it.

 

He swung his legs out of bed and stood up. As his bare feet hit the floorboards, a bizarre sensation washed over him. His balance was perfect. His vision, usually slightly fuzzy without his reading glasses, was hyper-focused. He could see the individual dust motes dancing in the sunbeams. He could hear the faint, rhythmic ticking of the wall clock in the living room through the closed door, a sound he had never noticed before.

 

His body was changing. The entity—whatever it was—was already altering his biology.

 

As he walked to the bathroom to splash cold water on his face, a sudden, sharp pressure spiked behind his eyes.

 

"Pathetic."

 

Izuku froze, his hands gripping the edges of the porcelain sink. His reflection in the mirror stared back at him, wide-eyed and terrified.

 

The voice didn't come from the room. It echoed from the deep recesses of his own skull. It was cold, aristocratic, and dripping with an ancient, unfathomable arrogance. It was the voice of the man from the alley.

 

"Who's there?" Izuku whispered frantically.

 

"You stand before a mirror, yet you cannot see your own insignificance," the voice reverberated, feeling like cold iron pressing against Izuku's brain. "I am Isshiki Ōtsutsuki. And you are my vessel. Though it disgusts me to reside within such a fragile, primitive shell."

 

Izuku’s breath hitched. "Get out of my head."

 

A dry, echoing chuckle filled his mind. "I am not merely in your head, boy. I am in your blood. I am in your cells. My Karma is unpacking my data into your biological matrix. Soon, 'you' will cease to exist, and I shall be reborn. Until then, do not attempt to speak to me, unless you wish to bore me to death."

 

The presence withdrew, retreating behind a heavy mental curtain, leaving a lingering, icy chill in Izuku’s chest.

 

Izuku gripped the sink until his knuckles turned white. He was infected. A parasite was slowly eating away at his existence. The sheer terror of it threatened to suffocate him, but then, a strange calmness—a synthetic, unnatural composure—washed over his panic. His erratic heartbeat slowed. His breathing steadied.

 

It wasn't his own calmness. It was the Karma, regulating his biological responses, forcefully suppressing his emotional distress to maintain the host's physical efficiency.

 

I have to pretend, Izuku thought, his green eyes hardening in the mirror. I have to pretend everything is normal until I can find a way to cut this thing out of me.

 

 

The school day passed in a blur of detached apathy. The taunts from Katsuki Bakugo and his lackeys, which would normally send Izuku spiraling into anxious muttering, barely registered. When Bakugo slammed his hands on Izuku's desk, creating miniature explosions, Izuku didn't flinch. He just stared at Bakugo's hands, his mind calculating the exact heat, velocity, and trajectory of the sparks. It was an analytical coldness that unnerved Bakugo enough to make him scowl and walk away without his usual barrage of insults.

 

The afternoon sun was beginning to dip below the horizon when Izuku began his walk home. He took a different route today, avoiding the alleyways. He walked through the bustling commercial district of Tatooin Shopping Center, his mind desperately trying to categorize the chaotic data of his new reality.

 

Suddenly, the ground trembled.

 

A cacophony of explosions shattered the afternoon peace, followed by the screams of civilians and the wail of sirens. A massive crowd had formed at the entrance of a nearby shopping arcade. Thick, acrid black smoke billowed into the sky, painting the clouds a bruised grey.

 

Izuku’s feet moved on instinct. Despite the alien presence in his blood, the heart of a hero still beat violently in his chest. He pushed his way through the dense crowd, squirming past the police barricades to get to the front line.

 

What he saw made his blood run cold.

 

It was the Sludge Villain. The same liquid, vile creature that All Might had saved him from yesterday under the bridge. The villain had grown massive, a swirling vortex of toxic green slime that was actively setting the surrounding shops on fire.

 

But that wasn't the worst part. Trapped within the suffocating mass of sludge, thrashing wildly and setting off desperate, localized explosions, was Katsuki Bakugo.

 

"Kacchan!" Izuku gasped.

 

He looked frantically around. Pro Heroes were on the scene. Death Arms, Kamui Woods, Mt. Lady, and Backdraft. But they were doing nothing.

 

"I can't get a grip on him!" Death Arms shouted, frustrated. "My Quirk is useless against fluid!"

"My wood will just catch fire!" Kamui Woods yelled, shielding his face from the heat.

"I need a minimum two-lane street to activate my Quirk!" Mt. Lady complained from the sidelines.

"We have to wait for someone with a suitable Quirk!"

 

Wait? Izuku's mind raced. They're just going to wait?! He's suffocating! By the time someone gets here, Kacchan will be dead!

 

Izuku’s eyes locked onto Bakugo’s. Through the thick, bubbling slime, Bakugo’s crimson eyes were wide with genuine, primal terror. They were begging for help.

 

Before his conscious mind could process the decision, before the fear could paralyze his legs, Izuku Midoriya vaulted over the police barricade and sprinted straight into the inferno.

 

"Hey, kid! Stop!" Death Arms roared, but Izuku was already too fast.

 

As Izuku sprinted toward the towering Sludge Villain, the cold, arrogant voice of Isshiki Ōtsutsuki violently invaded his mind.

 

"What are you doing, you miserable fool? The creature is vastly superior to your physical parameters. You will die, and my vessel will be destroyed!"

 

Shut up! Izuku screamed internally, his heroic resolve clashing violently against the alien's survival instinct. My legs moved on their own! I have to save him!

 

"Sentimental garbage! You cannot defeat it!"

 

Then give me the power to do it! Izuku roared back in his mind.

 

Whether it was a defensive mechanism triggered by the threat to the host's life, or Isshiki reluctantly yielding a fraction of power to ensure his own survival, Izuku felt the shift.

 

The heat in his left palm exploded into a searing, agonizing fire. Underneath his yellow glove, the black diamond began to pulse rapidly. Jagged, geometric lines of black ink shot out from the diamond, tearing through his glove, crawling up his forearm, his bicep, and stopping just below his shoulder. The lines glowed with a faint, malevolent crimson light.

 

Izuku didn't know what was happening, but he could suddenly feel the world around him on a molecular level. He felt a strange, foreign energy—Chakra—flooding his nervous system.

 

The Sludge Villain noticed him. "You again! The brat from yesterday! Die!"

 

A massive, thick tentacle of dense sludge whipped toward Izuku with enough force to shatter a concrete wall. Izuku didn't dodge. He didn't cower. His right eye twitched, his vision tunneling onto the incoming attack.

 

A word, an ancient concept, flashed into his mind. He didn't know what it meant, but his body knew how to execute it.

 

Sukunahikona.

 

Izuku thrust his left hand forward, palm facing the incoming tentacle.

 

There was no flash of light. There was no explosion. There was simply an instantaneous, physics-defying alteration of reality.

 

In a fraction of a millisecond, the massive sludge tentacle, which weighed several tons, simply ceased to exist in its current state. It was shrunk down to a microscopic level. The momentum of the attack vanished, leaving only a gentle breeze that rustled Izuku's green hair.

 

The crowd went dead silent. The Pro Heroes stared in utter disbelief. Even the Sludge Villain froze, its liquid eyes widening in confusion as it looked at its severed stump. "What... what did you just do?!"

 

Izuku didn't answer. He didn't have time. He lunged forward, closing the distance in a blur of speed that kicked up a cloud of dust behind him.

 

He planted his feet, twisting his hips, and drew back his right fist. He could feel the foreign energy—the chakra—coiling tightly around his knuckles, condensing into a dense, invisible gauntlet of raw kinetic power.

 

"Let him go!" Izuku roared.

 

He threw the punch.

 

He didn't hit the villain directly. He didn't have to. The sheer, terrifying output of the chakra-enhanced strike hit the air in front of the villain. The resulting shockwave was apocalyptic. A localized tornado of wind pressure erupted from Izuku's fist. The sheer concussive force instantly vaporized the moisture in the sludge, tearing the villain's liquid body apart on a molecular level.

 

The villain shrieked as it was scattered into a million droplets, raining down across the shopping district like dirty water. Bakugo fell to the ground, coughing violently, gasping for air.

 

Izuku stood frozen, his fist still extended. The air pressure from his punch continued upward, piercing the sky. The dark, smoke-filled clouds above the city were violently blown apart, split in two by the invisible pillar of force.

 

And then, it began to rain.

 

Izuku slowly lowered his arm. His breath came in ragged, heavy pants. He looked at his left arm. The black, glowing lines were rapidly receding, shrinking back down his arm, hiding themselves beneath the tattered remains of his yellow glove, returning to the diamond in his palm.

 

His body suddenly felt incredibly heavy, the adrenaline crashing. He fell to his knees on the wet pavement, staring at his hands.

 

What... what did I just do?

 

In the crowd, standing disguised among the civilians, a skeletal, blonde man watched the scene with wide, unblinking eyes. Toshinori Yagi—All Might—clutched the fabric over his heart. He had been a coward. He had let his time limit expire, leaving a child to do his job. But as he watched the green-haired boy shatter the villain and change the weather with a single blow, awe replaced his guilt.

 

My god, All Might thought. What incredible power. He told me he was Quirkless... but a Quirk of that magnitude...

 

All Might realized something profound in that moment. He had been looking for a successor for One For All. He had seen the heart of a hero in this boy yesterday. But seeing the raw, terrifying power the boy had just displayed, All Might made a decision.

 

He doesn't need my power. He is already a monster in his own right. The future of heroism is secure in his hands.

 

All Might turned and walked away into the rain, the mantle of One For All remaining safely hidden, never to be offered to Izuku Midoriya.

 

 

The sterile smell of the hospital waiting room was nauseating.

 

Izuku sat on the edge of the examination table, a fresh bandage wrapped around his scraped cheek. Across from him sat an exhausted-looking doctor holding a tablet, and beside the doctor was Inko Midoriya, who was actively dissolving into a puddle of tears.

 

Following the incident, the Pro Heroes had been a mix of furious and awestruck. They had scolded Izuku for his recklessness, but couldn't deny that he had saved the day with an overwhelming display of power. When the police questioned him about his Quirk—noting his registry as 'Quirkless'—Izuku panicked. He couldn't explain the alien. He couldn't explain the Karma. He had stammered, claiming he had no idea what happened, that it just "turned on."

 

The police had immediately escorted him to Musutafu General Hospital for a full biological screening.

 

"Well, Mrs. Midoriya," the doctor said, adjusting his glasses. "I have reviewed the bloodwork, the X-rays, and the genetic markers. It is incredibly rare, nearly unheard of in this generation, but the results are conclusive."

 

"W-What is it, doctor?" Inko sobbed, clutching a crumpled tissue. "Is my baby okay?"

 

"He is more than okay. He has experienced a Spontaneous Genetic Awakening. A late-blooming Quirk."

 

Izuku’s heart pounded. They think it's a Quirk.

 

"As you know, Quirks typically manifest by age four," the doctor explained, pulling up a holographic projection of Izuku's DNA. "However, in extremely rare cases, a child may possess a Quirk Factor that is dormant, locked behind a biological firewall. Our working theory is that the severe psychological trauma of being attacked by that villain yesterday, combined with the life-or-death adrenaline of saving his friend today, shattered that firewall. His body was forced to adapt to survive."

 

"A... a Quirk?" Inko whispered, turning to Izuku. She threw her arms around him, burying her face in his shoulder. "Oh, Izuku! I'm so sorry! I told you to give up, I didn't believe in you, but you had it all along! I'm so sorry!"

 

Izuku weakly hugged her back, his eyes hollow. "It's okay, Mom. It's okay."

 

"Based on the eyewitness reports and his physical readings," the doctor continued, typing on his tablet, "I am registering his Quirk as 'Matter Manipulation and Somatic Augmentation.' He seems to possess the ability to shrink matter upon command, and channel immense kinetic energy through his limbs. It is a dual-type emitter/enhancer. Frankly, it is one of the most powerful baseline Quirks I have ever seen."

 

The doctor smiled warmly at Izuku. "You're going to make a fine hero, young man."

 

Izuku forced a smile. A fake, fragile smile. "Thank you, doctor."

 

As they left the hospital, Izuku walked in silence, staring at his left hand. The world thought he was a late bloomer. They thought he was a miracle. But Izuku knew the terrifying truth. He hadn't been blessed by genetics. He had been cursed by a god. And this power wasn't a gift; it was a countdown to his own death.

 

 

The ten months leading up to the U.A. High School Entrance Exam were a period of hellish isolation and relentless, grueling training.

 

Izuku did not train to get stronger to pass a test. He trained to survive his own body.

 

He discovered Dagobah Municipal Beach Park, a beautiful coastline that had been illegally turned into a towering junkyard. It was secluded. It was perfect. Every morning at 4:00 AM, and every evening after school, Izuku came here to test the limits of the Karma.

 

He quickly realized that using the Karma's powers—the Sukunahikona (shrinking objects), the enhanced physical strength, and the sensory perception—took a massive toll on his stamina. If his physical vessel was weak, the Karma extracted faster. The alien data unraveled quicker when the host body was strained.

 

Therefore, Izuku resolved to forge his body into an indestructible fortress. He hauled refrigerators, crushed pickup trucks, and moved tons of scrap metal with his bare hands. He pushed his muscles until they tore, and pushed them again until they healed thicker.

 

But the physical strain was nothing compared to the psychological warfare.

 

Every night, when Izuku closed his eyes, he was pulled into his own mindscape.

 

It was a terrifying, infinite dimension of stark white space, dotted with massive, floating black cubes. And always, sitting atop the highest cube, looking down upon him like an emperor examining a rat, was Isshiki Ōtsutsuki.

 

In the mindscape, Isshiki appeared whole, uninjured, and resplendent in his white robes.

 

"Why do you persist in this futile physical labor?" Isshiki sneered during one of their nocturnal encounters, his voice echoing across the endless white void. "Moving trash. Lifting heavy objects. You behave like a beast of burden. It is degrading to the vessel of an Ōtsutsuki."

 

Izuku stood his ground at the base of the cube, glaring up at the alien. Ten months ago, he would have cowered. But the constant exposure to Isshiki's chakra was altering his personality. He was becoming less anxious, less timid. A cold, hardened edge was forming over his heart.

 

"I'm strengthening my body," Izuku replied evenly. "If I make this vessel stronger, it slows down your extraction process. I can feel it. You're barely at 15 percent."

 

Isshiki’s golden Dharma wheel eye spun lazily. "Perceptive for a primitive. Yes, a stronger vessel can temporarily throttle the Karma's data unpack. But it is merely delaying the inevitable. I have seeded my soul into your DNA. The process cannot be halted. It cannot be reversed. Eventually, Izuku Midoriya will die, and Isshiki Ōtsutsuki will rise."

 

"I won't let you," Izuku said, clenching his fists. "I'm going to be a hero. I'm going to save people. I will subjugate this power and use it to protect my world."

 

Isshiki threw his head back and laughed—a booming, terrifying sound that caused the giant black cubes to vibrate.

 

"Protect your world? You speak of heroism? Altruism is a disease of the weak, boy. You are a biological anomaly, yet you cling to the morality of insects. When I resurrect, do you know what I will do to this precious 'hero society' of yours?"

 

Isshiki leaned forward, his aura flaring, a suffocating pressure that forced Izuku to his knees within his own mind.

 

"I will plant a Ten-Tails. I will allow its roots to burrow deep into the crust of this planet. It will consume the ocean, the land, and the 'Quirk Factors' of every single human being alive. It will suck this world dry until it is a dead, floating rock, and it will bloom a Chakra Fruit of unimaginable power. Your heroes, your mother, your precious friends... they are nothing but fertilizer for my ascension."

 

Izuku trembled, his eyes wide with horror. The sheer scale of the malice was incomprehensible. This wasn't a villain robbing a bank or taking hostages. This was planetary genocide, spoken of with the casual indifference of a gardener pulling weeds.

 

"No..." Izuku whispered, forcing himself to stand up against the crushing spiritual gravity. He looked Isshiki dead in the eye. "I will master the Karma. I will use your own power against you. I will cage you inside me forever."

 

Isshiki smirked, amused by the defiance. "Try, vessel. We have all the time in the world."

 

Izuku woke up screaming, drenched in a cold sweat. He looked at his left hand. The black diamond stared back at him.

 

He had ten months. He had transformed Dagobah Beach from a dump into a pristine coastline. His physique had changed dramatically; the scrawny, trembling boy was gone, replaced by a teenager with dense, coiled muscle and eyes that carried the heavy, haunted weight of a veteran soldier.

 

He was ready for U.A. High School.

 

 

The gates of U.A. High School were massive, intimidating structures of glass and steel. As Izuku walked up the path, surrounded by hundreds of hopeful applicants, he felt entirely detached from the nervous energy buzzing around him.

 

A brown-haired girl tripped on the pavement near him. Izuku’s reflexes, honed by the Karma, were instantaneous. He caught her by the collar of her jacket before she hit the ground, easily hoisting her back to her feet with one hand.

 

"Oh! Thank you so much!" the girl, Ochaco Uraraka, beamed, her cheeks dusted with a permanent pink blush. "That was super fast! I was so nervous I tripped over my own feet. My Quirk is Zero Gravity, but I didn't activate it in time!"

 

"Be more careful," Izuku said, his voice flat, devoid of his former stuttering shyness. He released her collar and continued walking without looking back. Uraraka blinked in surprise, slightly put off by the cold dismissal, but hurried inside anyway.

 

The written exam was trivial. The Karma didn't just enhance Izuku's body; it accelerated his neural pathways. His brain processed information at an extraordinary rate. He finished the two-hour exam in forty-five minutes, spending the rest of the time meditating, actively suppressing Isshiki's whispers.

 

Then came the practical exam.

 

Izuku stood before the towering gates of Battle Center B. He was wearing a simple black tracksuit. He hadn't bothered with gauntlets or armor like some of the other examinees. The Karma was all the weapon he needed.

 

Present Mic’s voice boomed over the speakers. "START! What's wrong? There are no countdowns in real battles! Run, run, run!"

 

While the other students hesitated, Izuku vanished.

 

The sonic boom of his acceleration cracked the pavement where he stood. He rocketed down the main street of the faux city, a blur of motion.

 

A group of three 1-Pointer robots rolled out from an alleyway, their targeting lasers locking onto him. They fired a volley of missiles.

 

Izuku didn't break stride. His left hand twitched. The black diamond pulsed.

 

Sukunahikona.

 

In mid-air, the barrage of missiles suddenly shrank to the size of grains of rice. They pinged harmlessly against Izuku's chest like tiny pebbles. Before the robots could recalibrate, Izuku was upon them.

 

He didn't use flashy punches or dramatic kicks. He used lethal, calculated efficiency. He channeled a fraction of chakra into his right hand, making his fingers as rigid and sharp as steel blades. With three rapid, fluid motions, he drove his hand straight through the thick armor plating of the robots' central processing units, tearing out their wiring and crushing their cores.

 

The three robots sparked and collapsed.

 

Three points. Move.

 

For the next ten minutes, Izuku became a ghost of destruction. He moved with a grace and brutality that completely defied his age. When a massive 3-Pointer tried to crush him, he shrank it to the size of a toy car and crushed it under his heel. When a swarm of 2-Pointers surrounded him, he held out his hands.

 

He didn't fully understand how he did it, but the knowledge was seeping in from the Karma. He manipulated the ambient space.

 

Black Receivers.

 

From the palms of his hands, long, pitch-black metal rods materialized. They weren't created; they were summoned from a timeless pocket dimension where Isshiki stored his weapons. Izuku threw the rods like javelins. They moved faster than the eye could track, piercing the armor of the robots, disrupting their mechanical signals, and pinning them to the walls of the buildings.

 

In the dark observation room hidden deep within U.A., the faculty of Pro Heroes watched the monitors in stunned silence.

 

"Incredible," Midnight whispered, leaning closer to the screen. "His Quirk registry says Matter Manipulation and Augmentation... but the sheer versatility! He's shrinking objects, summoning weapons, and his physical output is off the charts."

 

"He's racked up seventy-four points already," Snipe noted, adjusting his mask. "He's completely dominating Battle Center B. He's not even sweating."

 

In the corner of the room, wrapped in a yellow sleeping bag, Shota Aizawa—Eraserhead—stared intensely at the monitor tracking Izuku Midoriya.

 

While the other heroes were impressed, Aizawa was disturbed.

 

"Look at his eyes," Aizawa muttered, his raspy voice cutting through the chatter.

 

The room quieted down. Present Mic looked at Aizawa. "What about 'em, Eraser?"

 

"Look at how he fights," Aizawa said, pointing a finger at the screen. The camera zoomed in on Izuku as he systematically dismantled a 3-Pointer. "There's no passion. There's no heroic drive. He's not fighting like a hero in training. He's exterminating them. He moves with zero wasted motion. He doesn't strike to disable; he strikes to obliterate. It's... surgical."

 

Aizawa narrowed his tired eyes. "That kid isn't fighting a mock battle. He moves like a veteran soldier who's been at war for decades. It's unnatural."

 

Principal Nezu, the small, chimera-like creature sitting at the control console, took a sip of tea. "An interesting observation, Aizawa. But raw potential cannot be denied. Let us see how he handles the ultimate obstacle."

 

Nezu slammed his paw down on a large red button.

 

Back in Battle Center B, the ground violently violently erupted.

 

The faux city shook as a colossus of green steel rose from the subterranean hangar. The 0-Pointer. It was larger than the tallest buildings in the arena, a mechanical titan designed to incite absolute terror and force the examinees to retreat.

 

The other students screamed and began running in the opposite direction. "Run! It's the 0-Pointer!"

 

Izuku stopped walking. He looked up at the towering machine.

 

"A massive, primitive toy," Isshiki's voice whispered in his mind, laced with boredom. "Destroy it and be done with this charade."

 

Izuku ignored the voice. He saw a flash of movement out of the corner of his eye. The brown-haired girl from earlier, Uraraka, was trapped under a massive chunk of rubble, her leg pinned. The 0-Pointer's massive treads were rolling forward, crushing everything in its path. She was going to be crushed.

 

Izuku didn't think. He breathed in, and allowed the Karma to advance to Stage 1.

 

The black diamond in his palm burned. The jagged lines shot up his arm, wrapping around his neck and spreading onto the left side of his face, stopping just beneath his eye. A terrifying, oppressive aura erupted from his body, cracking the pavement beneath him. The air pressure in the city dropped violently.

 

He bent his knees. And then, he jumped.

 

The force of his leap shattered a ten-meter radius of concrete into dust. Izuku shot into the air like a ballistic missile, hurtling straight toward the face of the 0-Pointer.

 

He didn't use Sukunahikona. He didn't use a black rod. He wanted to test the absolute limit of his augmented physical strength. He wanted to feel like he was in control.

 

He drew back his right fist. The chakra coalesced around his arm, glowing with a faint, ghostly blue light.

 

As he reached the apex of his jump, directly in front of the robot's massive optical sensor, Izuku unleashed the punch.

 

He didn't even make physical contact with the metal. The shockwave of kinetic energy—a localized, directed blast of gravity and air pressure—blasted forth from his fist.

 

The sound was deafening. The 0-Pointer's head simply crumpled inward as if hit by an invisible meteor. The force of the blow traveled down its spine, blowing out its back plating and sending a shockwave that parted the artificial clouds above the stadium. The massive titan halted, sparked, and then crashed backward in a spectacular explosion of fire and shrapnel.

 

Izuku landed gracefully on the ground, sliding a few feet before coming to a halt perfectly in front of the trapped Uraraka. He reached down, grabbed the ton of rubble pinning her leg, and tossed it away with one hand as if it were made of styrofoam.

 

The buzzer sounded. "TIME'S UP!"

 

The entire arena was silent. Uraraka stared at Izuku's back, her mouth hanging open, utterly terrified by the sheer magnitude of power she had just witnessed.

 

Izuku stood still, breathing heavily. The black marks slowly receded from his face, retreating down his neck and arm, back into the palm of his hand. He looked down at his right fist, which was completely undamaged.

 

He had won. He had secured his place at U.A. High School.

 

But as the adrenaline faded, the cold, mocking laughter of Isshiki Ōtsutsuki echoed in the empty halls of his mind.

 

"Impressive, my vessel. Keep growing stronger. Keep feeding the Karma. The stronger you become, the more glorious my resurrection shall be."

 

Izuku gripped his left wrist, his eyes shadowed. He had taken his first step toward becoming a hero. But the true war hadn't even begun. It was brewing right beneath his skin.

 

 

 

 

The bus ride to the Unforeseen Simulation Joint was suffocating.

 

Izuku Midoriya sat near the back, his head resting against the vibrating glass of the window. Outside, the bright morning sun bathed the city in a golden, optimistic hue, but inside Izuku’s mind, the temperature was constantly dropping.

 

It had been weeks since the U.A. Entrance Exam, and the isolation he had built around himself was becoming an impenetrable fortress. To Class 1-A, Izuku was an enigma. He was the boy who had shattered the 0-Pointer with a single, physics-defying punch, yet he spoke in flat, clipped sentences. He didn't engage in their banter. He didn't eat lunch in the cafeteria; he took nutrition pills and meditated in empty classrooms.

 

He wasn't trying to be cruel. He was terrified.

 

22 percent.

 

That was the number Izuku had deduced through his nocturnal interrogations of Isshiki in the mindscape. The Karma extraction was at 22 percent. Almost a quarter of his genetic code had been overwritten. The symptoms were becoming harder to mask. Sometimes, his vision would spontaneously shift, the world rendering into a spectral map of heat and energy—a nascent manifestation of the Byakugan. Worse still was the emotional blunting. When he saw people laughing on the street, he felt an uncomfortable, creeping apathy.

 

He was fighting a war on two fronts: the hero curriculum of U.A., and the alien parasite slowly deleting his soul.

 

"Hey, Midoriya?"

 

Izuku blinked, pulling his gaze from the window. Tsuyu Asui, a girl with striking frog-like features, was looking at him from across the aisle. The rest of the bus had quieted down, their attention drawn to the interaction.

 

"Yes, Asui?" Izuku replied, his voice level.

 

"I say whatever comes to mind, ribbit," she said, tilting her head. "Your Quirk... it's incredibly strong. But it doesn't feel like a normal Quirk. When you used it in the combat training yesterday against Bakugo, the air felt... heavy. Like it was hard to breathe. It's scary, ribbit."

 

Katsuki Bakugo, sitting three rows ahead, bristled. He glared over his shoulder, his crimson eyes burning with a mix of fury and intense confusion. Ever since Izuku had humiliated him in the Battle Trial by dodging his explosions with preternatural grace and pinning him with a single, impossibly strong hand, Bakugo had been silently boiling. A late bloomer, Bakugo had sneered. Bullshit.

 

Izuku looked down at his left hand, clad in its customary yellow glove. "My Quirk is... complicated," he said softly, terminating the conversation.

 

Uraraka, sitting next to Tsuyu, looked at Izuku with a mix of awe and pity. "You're always so serious, Midoriya. You can relax around us, you know! We're all going to be heroes together!"

 

"Heroes."

 

The voice echoed in Izuku’s skull, dripping with ancient, venomous contempt.

 

"They play dress-up in colorful garments, prattling about saving the weak. It is a nauseating display of biological inferiority. When I assume control, I shall silence their incessant, infantile chatter permanently."

 

Izuku gripped his kneecaps, his knuckles turning white. Leave them alone, he thought violently. Stay out of my head.

 

"I am not in your head, vessel. I am the blood in your veins. I am the marrow in your bones. You cannot silence the inevitable."

 

"We're here," Shota Aizawa’s tired voice cut through the bus over the intercom, saving Izuku from spiraling further into the mental abyss. "Quiet down and file out."

 

 

The Unforeseen Simulation Joint (U.S.J.) was a marvel of modern hero engineering—a massive, domed facility containing various disaster zones, ranging from a ruined city to a torrential flood zone.

 

The Space Hero, Thirteen, stood before the awe-struck students, delivering a passionate speech about the lethal potential of Quirks. "Powers are meant to save, not to kill. In this facility, you will learn how to use your Quirks to rescue those in need..."

 

Izuku listened intently. Powers are meant to save. He wanted to believe that. He needed to believe that. If he could master the Karma, maybe he could weaponize the powers of a god to save humanity.

 

Then, the lights cut out.

 

A heavy, mechanical groaning echoed through the dome as the facility's power grid failed. Down in the central plaza, the space above the fountain began to warp.

 

Izuku’s nascent sensory abilities flared instantly. The hair on his arms stood on end. He didn't just see the portal; he felt it. It was a spatial distortion, a tear in the fabric of reality, though vastly inferior to the dimensional rifts Isshiki could create.

 

A swirling vortex of purple and black mist expanded, and from its depths, a horde of grotesque, heavily armed villains began to pour out.

 

"Gather together and don't move!" Aizawa barked, his slouched posture vanishing instantly as he snapped his golden goggles over his eyes. "Thirteen, protect the students!"

 

"What is that?" Eijiro Kirishima asked, stepping backward. "Is this like the entrance exam? Does the training start already?"

 

"Don't move!" Aizawa roared, his capture weapon unfurling around him like a halo of serpents. "Those are real villains."

 

From the center of the mist emerged a man covered in disembodied hands, his pale blue hair falling over his face. Beside him stood a hulking, bio-engineered monstrosity—a creature with exposed brain tissue, a beak, and a body rippling with unnatural muscle mass. The Nomu.

 

"Eraserhead and Thirteen," the hand-covered man, Tomura Shigaraki, rasped, scratching his neck violently. "The teacher's schedule we received said All Might was supposed to be here. Where is he? I went through all the trouble of bringing this crowd... Is the Symbol of Peace not here?"

 

Shigaraki stopped scratching, a terrifying, manic smile spreading across his chapped lips. "Maybe if I kill some of these kids, he'll come out to play."

 

The mist villain, Kurogiri, expanded violently, rushing up the stairs toward the students faster than Thirteen could react.

 

"My job is to scatter you, and torture you to death!" Kurogiri announced.

 

Izuku’s left hand throbbed. He could have reacted. He could have used Sukunahikona to shrink the physical components of Kurogiri's neck brace, or channeled chakra into his legs to pull Uraraka and Iida out of the way. But fear hesitated his mind—not fear of the villains, but fear of releasing the seal in front of his classmates.

 

In that microsecond of hesitation, the dark mist swallowed them whole.

 

Izuku felt the disorienting pull of teleportation. He was spat out of the void, plunging downward into freezing, saline water. He had been dropped into the Shipwreck Zone.

 

Beneath the water, villains were already swarming like sharks. A man with a shark mutation lunged at Izuku, jaws unhinged.

 

Instinct overrode fear. Izuku didn't use the Karma's markings; he simply channeled a burst of raw, untethered chakra to his right leg and kicked the water. The kinetic force generated a localized pressure wave that acted like a depth charge, blowing the shark villain away and propelling Izuku out of the water. He landed gracefully on the deck of the sinking ship, completely dry, right next to a shivering Tsuyu and a sobbing Minoru Mineta.

 

From the deck, Izuku looked down at the central plaza.

 

Eraserhead was fighting like a demon, darting between dozens of villains, erasing their Quirks and incapacitating them with brutal martial arts. But he was fighting a war of attrition.

 

And then, the hulking creature with the exposed brain moved.

 

It was too fast. Aizawa blinked, and the Nomu was upon him. With a sickening crack that echoed throughout the dome, the Nomu shattered Aizawa's arm, slamming him into the concrete face-first. The creature pinned the Pro Hero, mercilessly snapping his other arm like a dry twig. Aizawa screamed in agony, his blood pooling on the ground.

 

"Mr. Aizawa!" Tsuyu gasped, her hands covering her mouth.

 

Izuku’s heart hammered against his ribs. The hero was being slaughtered.

 

"We have to help him," Izuku said, his voice cold, stripping away his panic.

 

"Are you crazy?!" Mineta shrieked, pulling at his own hair. "Did you see what that thing just did?! It broke a Pro Hero in half! We have to sit here and wait for All Might!"

 

"He'll be dead before All Might arrives," Izuku stated.

 

Without waiting for their approval, Izuku channeled chakra to his feet. He leaped from the sinking ship, crossing the massive distance of the flood zone in a single, impossible bound, landing silently at the edge of the central plaza, hidden behind a cluster of bushes. Tsuyu and Mineta, terrified to be left alone, followed him through the water, hiding just behind his position.

 

 

In the plaza, Shigaraki was bored. Aizawa was broken, a bloody mess beneath the Nomu's knee.

 

"This is pointless," Shigaraki muttered, scratching his neck again. "All Might isn't coming. Kurogiri, it's game over. Let's go home."

 

But before they left, Shigaraki’s eyes darted to the bushes. He had spotted them.

 

With a burst of speed, Shigaraki lunged forward, closing the distance to the bushes in a fraction of a second. His hand, the fingers outstretched, reached directly for Tsuyu's face.

 

Decay. Izuku had watched Shigaraki disintegrate Aizawa's elbow earlier. If those five fingers touched her, she would turn to dust.

 

Time seemed to slow down. Izuku’s left hand flared to life. The black diamond pulsed, but he didn't allow the marks to spread. He forced the raw chakra into his legs and right arm.

 

He moved faster than Shigaraki's eye could track.

 

Izuku materialized between Shigaraki and Tsuyu. He grabbed Shigaraki's wrist with his left hand—careful to only use four fingers, dodging the Quirk's activation requirement—and drove his chakra-enhanced right fist directly into Shigaraki's stomach.

 

The force of the blow was like a cannonball. Shigaraki’s eyes bugged out, saliva exploding from his mouth as the air pressure folded his body in half. He was launched backward, tumbling across the concrete plaza like a ragdoll.

 

"Midoriya!" Tsuyu cried out in relief.

 

But Izuku didn't celebrate. His eyes were locked on the Nomu.

 

Shigaraki groaned, slowly pushing himself up from the cracked pavement. "Nomu... kill that brat."

 

The bio-engineered monster shrieked, a terrifying, bird-like screech, and vanished from its spot above Aizawa.

 

Izuku’s enhanced senses screamed in warning. He crossed his arms over his chest, channeling every ounce of available chakra into his muscles to reinforce his bones.

 

The Nomu hit him like a freight train.

 

The impact sent Izuku skidding backward, his feet tearing deep trenches into the concrete. The physical power of the creature was astronomical—it rivaled, perhaps even exceeded, All Might's pure strength.

 

Izuku dropped his guard and thrust his left hand forward. Sukunahikona!

 

He focused his intent on the Nomu's massive arm, intending to shrink it to the size of a toothpick. The black diamond flared, but nothing happened.

 

"Idiot," Isshiki’s voice mocked in his mind, sharp and condescending. "Sukunahikona cannot shrink living organic matter, save for yourself. You cannot shrink the beast directly."

 

Dammit! Izuku realized, his eyes widening. I have to rely on blunt force!

 

Izuku ducked under a wildly swinging clothesline from the Nomu, pivoted, and drove a vicious uppercut into the creature's exposed jaw. The blow contained enough kinetic chakra to shatter a skyscraper. The Nomu's head snapped back with a crack like thunder.

 

But it didn't fall. It didn't even stumble.

 

The Nomu looked back down at Izuku, its lifeless, bulbous eyes completely devoid of pain.

 

"It's no use, kid!" Shigaraki laughed, wheezing from the punch he took earlier. "Nomu has Shock Absorption! Your physical attacks are completely nullified! He's a biological punching bag designed to take All Might at 100 percent!"

 

Before Izuku could retreat, the Nomu retaliated. It grabbed Izuku by his left arm. The grip was unbreakable.

 

With a brutal, mechanical twist, the Nomu wrenched Izuku’s arm.

 

SNAP.

 

The sound of Izuku's radius and ulna splintering echoed loudly in the plaza.

 

Izuku screamed, an agonizing, primal sound. His vision whited out from the pain. Before he could recover, the Nomu drove a knee directly into his chest. Izuku felt three ribs crack as he was launched into the air. The Nomu jumped, catching him mid-flight, and slammed both of its massive fists into Izuku's right arm and shoulder.

 

CRUNCH.

 

Izuku plummeted to the ground, bouncing once before coming to a halt in a broken, bloodied heap. Both of his arms lay at unnatural, mangled angles. The bones were shattered, piercing through muscle and skin in horrific compound fractures.

 

"Midoriya!" Mineta shrieked, bursting into tears.

 

Izuku tried to move, but his body wouldn't respond. The pain was absolute. He coughed, a spray of blood painting the concrete red.

 

The Nomu landed heavily next to him, raising its massive foot, preparing to stomp on Izuku's head and crush his skull like a melon.

 

Izuku looked past the giant, seeing Tsuyu and Mineta paralyzed by fear. He saw Aizawa, bleeding out. He saw the doors to the U.S.J. remaining firmly shut. All Might wasn't here. No one was coming to save them. He was going to die here, and his friends would be next.

 

No... Izuku thought, his tears mixing with the blood on his face. I can't... I can't let them die...

 

As the Nomu's foot began its descent, the world around Izuku abruptly stopped.

 

 

The deafening roar of the U.S.J. was replaced by a profound, echoing silence. The colors bled out of the world, shifting into a stark, blinding white.

 

Izuku was no longer lying on the broken concrete. He was standing—his arms fully healed—in the endless white expanse of his mindscape.

 

Floating above him, sitting comfortably on his throne of black geometric cubes, was Isshiki Ōtsutsuki. The alien god looked down at Izuku, swirling a phantom glass of dark red wine in his pale hand.

 

"A pathetic display," Isshiki remarked, taking a slow sip. "Your reliance on primitive martial arts against a bio-engineered anomaly is laughable. I told you, vessel. Your heroic ideals are a disease that will get you killed."

 

Izuku fell to his knees in the mindscape, clutching his chest. "Help me... please..."

 

Isshiki’s golden Dharma wheel eye narrowed. "You beg a god for salvation so you may continue playing dress-up with insects? You amuse me, Izuku Midoriya. If I allow that creature to crush your skull, the Karma will be destroyed, and my soul will be extinguished forever. Obviously, I will not allow that to happen."

 

Isshiki floated down from his cube, his white robes billowing in an ethereal wind. He landed gracefully in front of Izuku, towering over the boy.

 

"I can grant you the power to obliterate that creature," Isshiki said, his voice dropping to a seductive, resonant hum. "I can unlock the Karma to its Second Stage. I will feed you my combat experience, my ocular prowess, and my dimension-bending jutsu."

 

Isshiki leaned in, his pale face inches from Izuku’s.

 

"But the human brain cannot process the influx of an Ōtsutsuki's full battle data without fracturing. To survive the power, you must surrender the reins. You must let my consciousness pilot the vessel. You must let me out."

 

Izuku’s breath hitched. Let him out. He remembered Isshiki’s promise to consume the planet. If he let the alien take control, would he ever get his body back? Would Isshiki simply slaughter everyone in the U.S.J. himself?

 

"What's the matter, hero?" Isshiki mocked, his lips curling into a cruel smile. "Do you fear the monster within more than the monster without? Make your choice, boy. In the physical realm, that creature's foot is milliseconds away from turning your brain into paste. Die here with your friends, or let me take the wheel."

 

Izuku squeezed his eyes shut. He saw his mother's smile. He saw Uraraka's bright face. He saw Aizawa putting his life on the line.

 

If he died, they died.

 

"Just for a minute," Izuku whispered, opening his eyes, tears streaming down his face. "Save them. Save my friends. I surrender... just for a minute."

 

Isshiki’s smile widened into something truly demonic.

 

"Excellent."

 

Isshiki reached out and pressed his pale, cold palm against the center of Izuku’s forehead.

 

 

In the physical world, the Nomu's foot descended.

 

It never made contact.

 

A shockwave of sheer, concentrated energy erupted from Izuku's broken body. It wasn't air pressure. It was dark, malevolent, oppressive chakra. The shockwave blew the Nomu backward, its heavy feet skidding across the plaza.

 

Shigaraki shielded his eyes from the blast of dust, peering through his fingers. "What the hell? Did he have an explosion Quirk too?!"

 

The dust slowly settled.

 

In the center of the crater, Izuku Midoriya was standing. But he was no longer the boy who had walked into the U.S.J.

 

The black diamond in his left palm had exploded. Thick, jagged, crimson-black geometric lines crawled up his left arm, engulfing his neck, and spreading across the entire left hemisphere of his face. The marks pulsed with a rhythmic, terrifying heartbeat, glowing like embers in a furnace.

 

His broken arms hung uselessly at his sides for a mere second before the dark chakra forcibly snapped the bones back into place, knitting the flesh together with violent, agonizing speed.

 

But the most terrifying change was in his face.

 

Izuku’s right eye, normally a soft emerald green, had undergone a grotesque mutation. The iris had expanded, turning a milky, featureless white, while prominent, pulsing veins bulged violently around his temple. The Byakugan.

 

And from the left side of his head, tearing through his green hair and skull, a single, pale, jagged horn sprouted, curving upward like a demonic crown.

 

"Midoriya...?" Tsuyu whimpered from the bushes, her blood running cold.

 

The entity occupying the boy's body slowly rolled its neck, producing a series of loud, unnatural pops.

 

"This physical shell is agonizingly tight," the boy spoke.

 

It was Izuku's voice, but layered beneath it was a deep, resonating baritone—an ancient, metallic echo that vibrated the very air around them.

 

Shigaraki took a step back, his instincts screaming at him. The atmosphere in the U.S.J. had changed entirely. It felt as though a gravity manipulator had increased the world's weight by a factor of ten. It was hard to breathe. The killing intent radiating from the boy wasn't chaotic and wild like a villain's; it was utterly cold, refined, and absolute.

 

"Nomu!" Shigaraki yelled, a hint of panic entering his raspy voice. "Rip him apart!"

 

The Nomu shrieked and launched itself at "Izuku" with blinding speed, its fist drawn back for a fatal blow.

 

The boy didn't even assume a fighting stance. The white Byakugan eye twitched, locking onto the Nomu's muscular structure and chakra points in slow motion.

 

With effortless, liquid grace, the entity sidestepped the Nomu's punch by a millimeter.

 

"A crude biological toy," Isshiki's voice hissed from Izuku's lips. "You rely on shock absorption to compensate for your profound lack of technique."

 

The boy raised his left hand.

 

Daikokuten.

 

The space above the Nomu rippled, a portal opening to a dimension where time stood entirely still. From the void, a massive, pitch-black geometric cube—measuring twenty cubic meters and weighing thousands of tons—materialized out of thin air.

 

It dropped with the force of a meteor.

 

The black cube smashed directly down onto the Nomu, flattening the beast against the concrete with an earth-shattering BOOM. The shockwave shattered the glass dome of the U.S.J. and sent Shigaraki and Kurogiri flying.

 

The entire plaza cratered beneath the impossible weight of the alien relic.

 

Silence fell over the facility. Tsuyu, Mineta, and the other students who were watching from the cliffs were utterly speechless. A giant, black box had just fallen from the sky.

 

"Is... is it over?" Mineta squeaked.

 

A sickening, wet tearing sound echoed from beneath the cube.

 

The Nomu's raw physical strength, combined with its super regeneration, allowed it to push upward. Slowly, agonizingly, the beast lifted the massive black cube off its crushed body, its shattered bones knitting back together as it let out a furious roar.

 

"He's regenerating!" Shigaraki laughed hysterically. "I told you! Nomu is invincible! You can't crush him!"

 

The horned boy watched the Nomu lift the cube, utterly unimpressed.

 

"Regeneration. How tedious."

 

The boy raised his right hand, extending his palm toward the struggling Nomu. From the center of his palm, three long, jagged black rods materialized.

 

Sukunahikona.

 

In an instant, the three massive rods shrank down to a microscopic size, becoming smaller than grains of sand, completely invisible to the naked eye.

 

The boy flicked his wrist. The microscopic rods shot forward at relativistic speeds, piercing directly through the Nomu's exposed, mutated brain tissue.

 

"Restore."

 

Deep within the Nomu's brain cortex, the microscopic rods instantaneously returned to their original size.

 

The result was gruesome. Three massive, pitch-black metal spikes erupted from the inside of the Nomu's brain, impaling its skull from the inside out and protruding from its eye sockets and the back of its head.

 

The Nomu couldn't absorb the shock of an attack that originated inside its own grey matter. It couldn't regenerate around alien metal that disrupted its neural pathways and pinned its brain stem.

 

The beast dropped the massive black cube, falling to its knees, twitching violently. It let out one final, pathetic gurgle before its massive body collapsed completely, paralyzed and practically lobotomized by the Black Receivers.

 

The invincible monster had been dismantled in less than thirty seconds.

 

 

"No..." Shigaraki whispered, dropping to his knees. He began scratching his neck so violently that blood welled under his fingernails. "No, no, no! That was the anti-Symbol of Peace! That was my ultimate weapon! You cheated! What are you?!"

 

The horned boy turned his pale, venous right eye toward Shigaraki. The aura of death that washed over the villain was so potent that Shigaraki forgot how to breathe.

 

The boy raised his left hand, the black diamond glowing as another black rod materialized.

 

"You are vermin," the layered, ancient voice echoed. "And vermin must be exterminated."

 

"Kurogiri!" Shigaraki shrieked in absolute terror. "Get us out of here!"

 

The dark mist villain rapidly expanded, swallowing Shigaraki whole just as the horned boy threw the black rod. The projectile pierced the exact space where Shigaraki's head had been a microsecond earlier, burying itself entirely into the concrete wall of the U.S.J.

 

The villains were gone.

 

The plaza was eerily silent, save for the dripping of the flood zone waters and the groans of the injured Aizawa.

 

With a deafening CRASH, the massive front doors of the U.S.J. were blown off their hinges.

 

A massive, towering figure stood in the entryway, lacking his signature smile. Toshinori Yagi—All Might—had arrived, his suit bulging with untethered fury.

 

"Have no fear, students!" All Might roared, his voice booming across the facility. "Because I AM HERE!"

 

All Might leaped down to the central plaza, ready to do battle with the League of Villains. But he froze.

 

The villains were gone. In the center of a massively cratered plaza lay a mangled, monstrous corpse impaled by black metal spikes. A colossal, unexplainable black cube rested nearby. And standing amidst the carnage was a boy.

 

A boy with black, demonic tattoos covering his skin, a milky, veined eye, and a pale horn jutting from his skull.

 

All Might recognized the green hair. "Young... Midoriya?"

 

All Might didn't feel relief. He felt a profound, chilling instinct to fight. His body braced itself, recognizing the entity standing before him not as a student, but as an apocalyptic threat.

 

The horned boy turned to look at All Might. A cold, arrogant smirk tugged at the corner of his mouth.

 

No!

 

Deep within the recesses of his hijacked mind, Izuku’s consciousness violently rebelled. He had struck a deal to save his friends, not to slaughter them. Isshiki had done his part. Now, Izuku had to take the reins back before Isshiki decided to test his power against the Symbol of Peace.

 

Give it back! Izuku roared in his mindscape, throwing himself against the invisible chains Isshiki had bound him with.

 

"Quiet, vessel," Isshiki hissed mentally. "The supreme warrior of this world stands before us. Let us see if he bleeds."

 

NO!

 

Izuku forced every ounce of his willpower, every shred of his soul, into suppressing the alien chakra. He visualized a steel vault slamming shut.

 

In the physical world, the boy's body convulsed. He gripped the left side of his face, letting out a guttural, agonizing scream.

 

"Midoriya!" All Might shouted, taking a cautious step forward.

 

The pale horn jutting from the boy's skull cracked, then crumbled into ash, dissolving into the wind. The bulging veins around his right eye receded, the milky white color bleeding away to reveal his natural emerald green. The dark, menacing tattoos shrank rapidly, pulling back down his neck, down his arm, and sealing themselves back into the black diamond on his palm.

 

The suffocating gravity in the room lifted instantly.

 

Izuku’s body, suddenly deprived of the god-like chakra keeping him standing, collapsed like a severed marionette. He hit his knees, clutching his chest, gasping for air as if he had been drowning.

 

He looked around. He saw the mangled, impaled Nomu. He saw the massive black cube. He looked over to the bushes and saw Tsuyu and Mineta.

 

They weren't looking at him with the relief and awe reserved for a hero who had just saved their lives. They were looking at him with unadulterated, primal fear. Tsuyu was trembling violently, backing away from him.

 

Izuku looked up at All Might. The Symbol of Peace was standing in a defensive posture, his fists clenched, his blue eyes guarded and wary.

 

They're terrified of me, Izuku realized, his heart shattering into a thousand pieces. I saved them... but they think I'm a monster.

 

He looked down at his left hand. The black diamond sat quietly on his palm, an indelible reminder of the devil inside him.

 

Izuku wrapped his right hand over the diamond, bowed his head to the cracked concrete, and began to sob. He wept not from the lingering pain in his newly healed bones, but from the terrifying realization that he had just surrendered a piece of his soul to the devil. And next time, the devil might not give it back.

 

 

 

 

The human soul is a fragile construct, built upon a foundation of memories, empathy, and the warmth of shared experiences. For Izuku Midoriya, that foundation was dissolving into ice.

 

It had been a month since the U.S.J. Incident. The physical wounds had healed instantly, knit together by alien chakra, but the psychological scars were festering. Class 1-A had tried to return to normalcy, but a thick, invisible wall now stood between Izuku and his peers.

 

They didn't bully him. It was worse; they handled him like an unexploded bomb.

 

When he walked into the classroom, conversations hushed. When he sparred in Hero Basic Training, his classmates would flinch at his movements. They had seen the horn. They had seen the monstrous black cube crush the indestructible Nomu. They had felt the suffocating, murderous gravity of his aura. Tsuyu couldn't look him in the eye. Mineta actively hid from him. Even Katsuki Bakugo, whose entire personality was built on aggressive dominance, gave Izuku a wide, wary berth.

 

But the isolation wasn't the most terrifying part. The most terrifying part was that Izuku was starting to not care.

 

Fifty percent.

 

That was the conclusion Izuku had reached. The Karma seal was a compressed zip file of an alien god's genetic sequence, and it was now half-unpacked. His DNA was literally mutating, bridging the gap between human and Ōtsutsuki.

 

The physical symptoms were undeniable. His natural body temperature had dropped, leaving his skin constantly cool to the touch. His dietary needs plummeted; the ambient chakra his body now naturally produced sustained his cells, making food taste like bland ash. Occasionally, his right eye would pulse with a dull ache, threatening to shift into the Byakugan without his command.

 

But the psychological symptoms were a living nightmare.

 

One evening, Izuku had sat on the couch with his mother to watch a tragic drama movie—one that usually had them both bawling their eyes out by the second act. When the heartbreaking climax occurred on screen, Inko Midoriya wept openly.

 

Izuku just stared at the television. He felt a faint pressure in his chest, a ghost of a memory that told him he should be crying, but the tears wouldn't come. His emotional receptors were being actively numbed, overwritten by a biological imperative that viewed empathy as a weakness.

 

He was becoming cold. Calculating. Detached.

 

"You mourn the loss of your fragility," Isshiki whispered in the dark corners of Izuku's mind one night. "Do you weep when you shed a dirty garment? I am burning away your mortal flaws, vessel. I am elevating you."

 

You're killing me, Izuku had replied, staring blankly at his bedroom ceiling.

 

"I am replacing you. There is a difference."

 

When U.A. High School announced the upcoming Sports Festival, the entire nation buzzed with excitement. For the students, it was a chance to be scouted by Pro Heroes.

 

For Izuku, it was a desperate, life-or-death bid for his own soul.

 

He needed to stand on that stage, in front of the entire world, and prove that he was still human. He needed to fight like a hero, smile like a hero, and suppress the alien parasite in front of millions. If he let Isshiki dictate his actions, if he yielded to the apathy and the malice, he would lose himself completely before the extraction even reached a hundred percent.

 

He had to win. But he had to win as Izuku Midoriya.

 

 

The roar of the U.A. stadium was deafening, a tidal wave of sound generated by tens of thousands of spectators.

 

Izuku stood in the tunnel waiting for Class 1-A to be called out. His classmates were jittery, shaking out their nerves. Izuku stood perfectly still, his eyes closed, focusing entirely on a visualization technique to keep his internal temperature warm. He had to force himself to feel the excitement.

 

During the two weeks leading up to the festival, Shoto Todoroki had approached him. The boy with the dual-temperature Quirk had looked Izuku in the eye and declared war.

 

"I don't know what you are, Midoriya. All Might has his eye on you. But looking at you... I feel a chill that has nothing to do with my ice. I'm going to beat you, and I'm going to do it using only my right side. Only my mother's power."

 

Normally, a declaration like that would have sent the old Izuku into a nervous spiral. But the current Izuku had simply nodded, his face an impassive mask. "I look forward to it, Todoroki."

 

When the festival began, Izuku's performance was a terrifying display of controlled minimalism.

 

In the Obstacle Race, he didn't use the flashy, explosive power he had shown at the Entrance Exam. He didn't want to scare the crowd. Instead, he channeled a tiny, regulated stream of chakra to his muscles, augmenting his speed and agility. When the massive 0-Pointer robots appeared, he didn't obliterate them. He simply used Sukunahikona to shrink their hydraulic fluid lines to microscopic sizes, causing the robots to freeze and collapse internally while he leaped gracefully over them. He took first place without breaking a sweat, his breathing completely even.

 

In the Cavalry Battle, he played the role of the rider. He teamed up with Uraraka, Hatsume, and Tokoyami. He didn't summon black rods or use gravity-crushing shockwaves. He relied on brilliant tactical analysis, directing Tokoyami's Dark Shadow and utilizing Uraraka's weightlessness to evade. When Todoroki unleashed a massive glacier to freeze them, Izuku simply held out his left hand—the black diamond hidden beneath a sports bandage—and shrank the incoming ice spikes into harmless snowflakes.

 

He was dominating, but the crowd's reaction was muted.

 

In the commentator's booth, Eraserhead stared at the monitors. "He's holding back," Aizawa muttered into the microphone.

 

"Holding back?!" Present Mic yelled. "Eraser, the kid is completely untouched! He's a ghost out there!"

 

"He's not fighting," Aizawa corrected, his eyes narrowing. "He's managing a situation. It's like watching a grandmaster play chess against toddlers. He is exerting the exact minimum amount of effort required to achieve victory. There's no passion."

 

Aizawa was right. Izuku felt hollow. He was winning, but the victories felt like ash on his tongue. The alien apathy was winning the internal war.

 

Until the semi-finals.

 

 

The concrete arena was meticulously swept. The sun beat down on the stadium, but the air above the fighting ring was already plunging to freezing temperatures.

 

"In this corner!" Present Mic's voice boomed over the speakers. "He's been a stoic ghost of victory all day, the boy with the most terrifyingly efficient Quirk in the first year! From the Hero Course, Izuku Midoriya!"

 

The crowd offered a respectful, if slightly unnerved, round of applause.

 

"And in this corner! The prodigy of ice and fire, though we've only seen the ice today! Also from the Hero Course, Shoto Todoroki!"

 

Todoroki stood across the ring, his breath visibly pluming in the air. The right side of his body was already encased in a thin layer of frost. His mismatched eyes were locked onto Izuku with intense, unresolved fury.

 

Izuku stood loosely, his arms at his sides. He took a deep breath, trying to force his heart rate up. Feel something, he commanded himself. He is in pain. He is rejecting half of himself because of his father's abuse. You have to save him.

 

"Why?" Isshiki’s cold voice echoed, slicing through Izuku's thoughts. "His trauma is biologically irrelevant. He artificially limits his own combat potential over a petty paternal grievance. Crush him and be done with it."

 

No, Izuku thought, his jaw clenching.

 

"Begin!" Midnight called out, cracking her whip.

 

Todoroki didn't hesitate. He slammed his right foot onto the concrete. A massive, jagged glacier of solid ice erupted from the ground, racing toward Izuku at breakneck speed. It was a localized apocalypse, dropping the temperature of the entire stadium by ten degrees in a second.

 

Izuku didn't move. He raised his left hand, the bandage wrapping his palm glowing faintly with red light beneath the fabric.

 

Sukunahikona.

 

He didn't shrink the whole glacier. He calculated the structural load-bearing points of the ice wave. With microscopic precision, he shrank the foundational ice pillars connecting the glacier to the ground.

 

The massive tidal wave of ice, suddenly lacking a foundation, shattered under its own immense weight. It exploded into a cloud of glittering, freezing mist mere inches from Izuku's face.

 

The crowd gasped. Todoroki's eyes widened in shock.

 

"What happened?!" Present Mic yelled. "Todoroki's ice just collapsed before it could touch him!"

 

Todoroki gritted his teeth and sent another wave, faster and sharper than the last. Again, Izuku waved his hand, and the ice disintegrated into powdery snow.

 

"Is that all?" Izuku asked, his voice projecting across the ring. He wanted to sound compassionate, to goad Todoroki into using his fire, but the Karma tainted his tone. It came out sounding profoundly bored and condescending.

 

Todoroki's face twisted in anger. "Don't mock me!"

 

He sprinted forward, launching a continuous barrage of ice projectiles. Izuku bobbed and weaved, his augmented reflexes making Todoroki look like he was moving in slow motion. Izuku slipped inside Todoroki's guard and delivered a swift, precise, open-palm strike to Todoroki's sternum.

 

The physical force, enhanced by a sliver of chakra, sent Todoroki skidding backward across the ring, gasping for air. Frostbite was beginning to creep up Todoroki's right arm. He was shivering violently, his own Quirk slowly freezing his internal organs.

 

"You're trembling, Todoroki," Izuku said, taking a step forward. He tried to force the warmth into his words. "Quirks are physical abilities. They have limits. You're freezing yourself to death. Use your left side!"

 

"Shut up!" Todoroki screamed, sending a desperate, massive pillar of ice.

 

Izuku didn't shrink it this time. He channeled chakra into his right leg and kicked the ice pillar, shattering it into a million pieces with raw kinetic force.

 

"Everyone here is giving it their all!" Izuku shouted, his voice cracking slightly, a sliver of genuine, human desperation bleeding through the alien apathy. "They want to be heroes! And you think you can win with half your strength?! You haven't put a single scratch on me!"

 

In the VIP box, Endeavor's flames flared angrily. "Shoto! Stop playing around and use my fire!"

 

Todoroki clutched his freezing right arm. "I will win... with my mother's power... I reject him..."

 

"It's not his power!" Izuku roared, finally tapping into his own soul, pushing past the coldness of the Karma. He pointed a finger at Todoroki. "It's YOURS! Your power, not his!"

 

The words struck Todoroki like a physical blow. The memory of his mother, the memory of her telling him he could be whatever he wanted, shattered his mental blockade.

 

A blinding, intense heat erupted from the left side of Todoroki's body. The frost covering him instantly melted, turning to steam. Brilliant, roaring crimson flames engulfed his left side, painting the arena in a searing, beautiful light.

 

The crowd erupted. Endeavor roared in triumph.

 

Todoroki looked at his burning left hand, tears evaporating from his eyes. He looked up at Izuku and smiled—a terrifying, liberated smile. "You're crazy, Midoriya. Trying to save your opponent during a tournament..."

 

Izuku’s heart soared. He felt it. A genuine rush of human adrenaline. Empathy. Joy. He had reached him. He had acted like a hero.

 

But deep within the recesses of his DNA, the alien god was absolutely disgusted.

 

"Enough of this nauseating pantomime."

 

Suddenly, an agonizing spike of pain drove itself directly into Izuku's brain. It was so intense that his vision whited out, and his knees buckled. He gasped, dropping to one knee on the concrete, clutching his head.

 

"Midoriya?" Todoroki faltered, the flames flickering.

 

Underneath the bandages on Izuku's left hand, the black diamond ignited like a dying star. The fabric of the bandage burned away, turning to ash, revealing the jagged, geometric Karma markings.

 

Against Izuku's will, the dark, crimson-black lines began to spread rapidly. They tore up his left arm, crawled up his neck, and mapped themselves across the left side of his face. His right eye throbbed violently, the pupil contracting, the iris beginning to bleach into the milky white of the Byakugan.

 

A suffocating, demonic aura exploded from Izuku's body, extinguishing Todoroki's flames instantly, sucking the oxygen out of the arena.

 

"You dare infect my vessel with this pathetic sentimentality?" Isshiki's voice roared, seizing control of Izuku's vocal cords. The voice was distorted, layered with a metallic, cosmic malice. "I will show you what true power is, insect!"

 

Izuku's right hand shot forward, pointing at Todoroki. The space around Todoroki began to warp. A massive, crushing gravitational force—the prelude to Daikokuten—began to form above the boy. If it dropped, Todoroki would be pulverized into a bloody paste on live television.

 

NO! Izuku screamed internally. I won't let you!

 

In a final, desperate act of rebellion, Izuku forced his own chakra to crash against Isshiki's. He visualized slamming his own hands around the alien's throat.

 

The conflicting energies caused a catastrophic biological short-circuit.

 

The world in the stadium violently froze.

 

The roaring crowd, the billowing steam, Todoroki's shocked face, the debris in the air—everything stopped dead. Time itself ceased to flow in the physical realm as the internal conflict achieved critical mass, violently pulling Izuku's consciousness directly into the mindscape.

 

 

Izuku fell to the floor, gasping for air.

 

He was back in the stark, infinite white expanse. Above him floated the massive, black geometric cubes. The air here was heavy, vibrating with an oppressive, god-like fury.

 

"You dare resist me in the midst of combat?!"

 

Isshiki Ōtsutsuki floated down from his throne, his white robes snapping in an ethereal wind. He did not look amused. He did not look arrogant. He looked genuinely, murderously furious. His golden right eye spun rapidly, exuding a pressure that forced Izuku flat onto his stomach.

 

"I... I will not... let you kill him..." Izuku gritted his teeth, his muscles screaming as he slowly forced himself to his hands and knees.

 

Isshiki sneered, landing gently before the struggling boy. "You value the life of one insignificant human over the evolution of this vessel? You are truly a defect. The extraction is at fifty percent. You are half of me, yet you cling to the dirt."

 

Isshiki grabbed Izuku by the collar of his shirt, lifting him effortlessly into the air.

 

"Let me enlighten you, boy, as to why your heroism is a cosmic joke," Isshiki hissed, his golden eye burning into Izuku's soul.

 

Isshiki waved his pale hand. The white expanse of the mindscape shattered, replaced by a terrifying, hyper-realistic illusion.

 

Izuku found himself floating above the Earth. But it wasn't the Earth he knew. The oceans were boiled dry, turning into vast basins of cracked, lifeless mud. The continents were barren, stripped of all green, all cities, all life.

 

In the center of the world stood a tree of unimaginable proportions. Its roots wrapped around the entire globe, plunging deep into the mantle. The trunk pierced the stratosphere, and at its zenith bloomed a massive, terrifying flower.

 

"This is the fate of your world," Isshiki's voice boomed from everywhere at once. "This is a Divine Tree. And to feed it, I will plant the Ten-Tails."

 

The illusion shifted. Izuku saw a monstrous, towering beast with ten thrashing tails, a single massive eye containing the Rinne Sharingan, and a maw that could swallow mountains. He watched in horror as the beast unleashed indiscriminate, apocalyptic destruction upon cities, devouring millions of humans, absorbing their Quirks and their life force to cultivate a single, glowing Chakra Fruit.

 

"Your heroes? Your Symbol of Peace? They will be nothing but nutrients in the soil," Isshiki mocked as the illusion faded back to the white void. Isshiki dropped Izuku onto the floor. "Your struggles in that arena are the thrashings of a microscopic organism in a petri dish. Yield to me. Let the Karma take full control, and I will grant you a swift death before the harvest begins."

 

Izuku lay on the white floor, trembling.

 

The scale of the horror was paralyzing. He wasn't fighting a villain who wanted to change society. He was carrying an entity that viewed planetary genocide as basic agriculture.

 

The despair threatened to drown him. The coldness creeping through his DNA told him to give up. It told him that Isshiki was a god, and he was nothing.

 

But then, Izuku remembered Todoroki's face. He remembered the boy's liberated smile when he finally embraced his own fire. He remembered All Might's words on the rooftop, 'Pros are always risking their lives.'

 

A hero, Izuku thought, his tears drying as a deep, burning fire ignited in his core, doesn't give up just because the villain is stronger. A hero smiles in the face of despair.

 

Izuku slowly placed his hands on the ground and pushed himself up.

 

"You call us insects," Izuku whispered, his voice trembling, not with fear, but with an overwhelming, indomitable rage. "You call us primitive."

 

Isshiki narrowed his eyes. "You still have words?"

 

Izuku stood up entirely. He looked the alien god dead in the eye.

 

"You have all this power. You can cross dimensions. You can manipulate time. But you're a coward," Izuku said, his voice steadily rising. "You conquer planets because you're empty! You're a parasite! You don't know what it means to struggle, to bleed for someone else, to protect something fragile!"

 

Isshiki's face twisted into an ugly snarl. "Silence!"

 

He reached out, intent on crushing Izuku's spiritual form with a gravitational wave.

 

But it didn't work.

 

Izuku didn't flinch. Instead, he took a step forward. "This is my mind! This is my soul! You are a guest in my body, and I AM EVICTING YOU!"

 

Izuku thrust his hands forward. He didn't use the Karma's power. He used his own human willpower, fueled by the love of his mother, the inspiration of All Might, and the desperate desire to save Shoto Todoroki.

 

From the white floor of the mindscape, brilliant, glowing green and blue chains erupted. They were forged not of metal, but of pure spiritual energy—the physical manifestation of Izuku Midoriya's unbreakable heroic heart.

 

The chains shot forward, wrapping around Isshiki's arms, his torso, and his neck.

 

"What is this?!" Isshiki roared, struggling against the bindings. The alien god found, to his absolute shock, that he couldn't break them. The chains were anchored to Izuku's humanity, which was currently burning brighter than Isshiki's malice.

 

"I am taking the power," Izuku declared, his eyes blazing with a fierce, emerald light. "I am going to use your strength to protect the people you want to destroy. I will chain you in the darkest corner of my soul until the day I die!"

 

With a mighty pull, Izuku yanked the chains. Isshiki Ōtsutsuki, the conqueror of worlds, was violently dragged down, slamming into the white floor.

 

"YOU MISERABLE, PRIMITIVE BRAT!" Isshiki shrieked, his composure completely shattered. "I WILL TEAR YOUR SOUL APART!"

 

"Watch me," Izuku said, turning his back on the screaming god.

 

He closed his eyes, and shattered the mindscape.

 

 

Time instantly resumed in the U.A. stadium.

 

The crowd was screaming. The steam was billowing. The massive, invisible weight of Isshiki's gravity was a millisecond away from dropping on Todoroki.

 

But it vanished.

 

The crushing, demonic aura that had suffocated the arena instantly evaporated, replaced by a sudden, rushing wave of clean, warm air.

 

Todoroki gasped, falling to one knee, the flames on his left side reigniting. He looked up, expecting to be destroyed by the terrifying monster that Midoriya had briefly become.

 

But Izuku wasn't a monster anymore.

 

The jagged, crimson-black geometric lines covering his arm and face began to change. The malevolent red glow shifted, pulsing rapidly until it shattered into a brilliant, luminous, sapphire blue.

 

Weaponized Karma.

 

Izuku stood in the center of the ring, his green eyes clear and sharp, completely devoid of the Byakugan's influence. The blue Karma markings pulsed gently on his skin, no longer a parasite's brand, but a hero's armor. He had forcefully subjugated the chakra, filtering out Isshiki's malice and purifying the power with his own heroic will.

 

Izuku looked at his glowing blue hands. He felt warm. He felt alive. He felt... like himself.

 

He looked up at Todoroki, and for the first time in a month, Izuku Midoriya smiled. It wasn't the cold smirk of an alien god. It was a bright, radiant, heroic smile that rivaled the sun.

 

"Come on, Todoroki!" Izuku shouted, dropping into a martial arts stance, the blue chakra flaring around him like a protective aura. "Give me everything you've got!"

 

Todoroki stared in awe, the fear washing away, replaced by an overwhelming surge of competitive respect. He smiled back. "You're on, Midoriya!"

 

Todoroki unleashed a simultaneous wave of freezing ice and roaring fire. The clash of extreme temperatures created a massive, violent expansion of superheated air—a localized explosion that tore up the concrete floor of the arena.

 

Izuku didn't shrink the attack. He wanted to meet Todoroki's spirit head-on.

 

He channeled the purified blue chakra into his legs. Shoot Style.

 

Izuku bounded forward, using the falling chunks of concrete as stepping stones, defying gravity. He weaved through the torrent of fire and ice with blinding speed. He didn't use the Karma's spatial hax; he used his own tactical brilliance combined with raw physical augmentation.

 

He breached Todoroki's defense.

 

"Take this!" Izuku yelled, spinning in mid-air. He channeled the kinetic energy into his right leg, executing a devastating, sweeping roundhouse kick.

 

He intentionally pulled the strike at the very last microsecond, making sure his physical foot didn't make contact with Todoroki's skull. Instead, he released a localized, controlled burst of wind pressure—a miniaturized, horizontal hurricane.

 

The concussive force hit Todoroki like a wall of solid air. The boy of ice and fire was lifted off his feet, carried backward through the air, and sent tumbling gently out of bounds, landing on the grass outside the concrete ring.

 

The massive cloud of steam slowly cleared.

 

Izuku stood alone in the center of the ruined arena. The blue Karma markings gently receded from his face, shrinking down his arm, and returning to the black diamond in his palm, completely obedient to his will.

 

Midnight stared at the ring in shock before raising her whip. "Todoroki is out of bounds! Midoriya advances to the finals!"

 

The stadium was dead silent for three seconds. Then, it erupted. The roar was deafening, a cascade of cheers, applause, and whistles. They had witnessed a terrifying display of power, but it had ended with a heroic, non-lethal victory.

 

In the commentator's booth, Aizawa let out a breath he didn't know he was holding. He looked at Izuku's smiling face on the monitor. "He found his heart," Aizawa muttered softly.

 

Down in the ring, Izuku walked over to the boundary line and offered his hand to Todoroki.

 

Todoroki looked at the hand, then up at Izuku's beaming face. He took it, allowing Izuku to haul him to his feet.

 

"Thank you," Todoroki said quietly, his mismatched eyes soft. "You saved me, Midoriya."

 

"We're heroes," Izuku replied, his voice thick with emotion. "It's what we do."

 

As Izuku walked back into the dark tunnel of the stadium, away from the cheering crowds, he finally allowed the dam to break. The emotional numbness that had plagued him for a month shattered completely.

 

Hot, heavy tears streamed down his freckled cheeks. He leaned against the concrete wall of the tunnel, burying his face in his hands, crying tears of profound, overwhelming joy. He was still here. He was still Izuku. He had looked into the abyss of a god, and he had not blinked.

 

He had won the war within.

 

But as he cried, he looked down at his left palm. The black diamond sat quietly, dormant. Izuku knew the truth. He had won a battle, yes. He had forged chains of willpower. But chains rust. Willpower wavers. The extraction was at fifty percent, and Isshiki was far from dead.

 

The clock was still ticking, but for today, Izuku Midoriya was the master of his own fate.

 

 

 

 

 

 

The silence in Principal Nezu’s office was absolute, heavy, and suffocating.

 

It was the Monday following the U.A. Sports Festival. The world outside was still buzzing with the excitement of the tournament, the news anchors endlessly looping footage of Izuku Midoriya’s spectacular, gravity-defying victory over Shoto Todoroki. To the public, Midoriya was a prodigy, a rising star with a Quirk so versatile it defied classification.

 

But inside the soundproof, reinforced walls of the principal's office, there was no celebration. There was only a terrifying, clinical dread.

 

Izuku sat in a high-backed leather chair, his hands resting on his knees. He wore his standard U.A. uniform, though his left hand remained wrapped in white medical tape to conceal the black diamond.

 

Across from him sat four men who represented the absolute pinnacle of hero society’s authority.

 

Principal Nezu, the hyper-intelligent chimera, sat behind his mahogany desk, his paws steepled, his usually cheerful black eyes unreadable. To his right stood Toshinori Yagi—All Might in his skeletal form—who looked exceptionally pale, his sunken blue eyes fixed on Izuku with a mix of awe and profound concern. To Nezu's left stood Shota Aizawa, heavily bandaged from the U.S.J. incident, his one visible eye piercing straight through Izuku’s defenses.

 

And standing nearest to the door, serving as the arbiter of this clandestine meeting, was Detective Naomasa Tsukauchi.

 

"Midoriya," Nezu began, his voice devoid of its usual chipper cadence. "You are not in trouble. I want to make that explicitly clear. You are a hero in training who has acted with exemplary valor. However, the faculty has noticed... inconsistencies regarding your Quirk."

 

Aizawa leaned forward. "A horn at the U.S.J. A spatial distortion that dropped a massive black cube from a pocket dimension. A sudden shift in your biological aura that suffocated a veteran villain. And at the festival, your markings shifted from a dark crimson to a brilliant blue, completely altering your combat parameters."

 

Aizawa’s eye narrowed. "The hospital registered you as a late bloomer with a 'Matter Manipulation and Somatic Augmentation' Quirk. But Quirks abide by the laws of physics. They are biological functions. What you are doing... it is bending the fundamental laws of reality. We need the truth, Midoriya."

 

Izuku looked down at his taped left hand. He had known this day was coming. After conquering his inner demon during the fight with Todoroki, he had made a decision. He could no longer carry the weight of the universe alone.

 

"Detective Tsukauchi," Izuku said softly, his voice echoing in the quiet room. "Your Quirk. It's a polygraph, isn't it? You can tell when someone is lying."

 

Tsukauchi blinked, surprised by the boy's sharp deduction, but nodded. "Yes. As long as I hear your voice, I can detect any falsehood based on your intent."

 

"Good," Izuku said, taking a deep, shuddering breath. "Because what I am about to tell you is going to sound like absolute insanity. But I need you to know that every single word is true."

 

Izuku slowly unraveled the white medical tape from his left hand. The fabric fell away, revealing the pitch-black, geometric diamond stamped into the center of his palm.

 

"This is not a Quirk," Izuku stated, looking up at the four adults. "It's called a Karma seal. It is a highly compressed biological backup file... of a god."

 

Tsukauchi gasped, his eyes widening. He looked at Nezu and All Might. "True," the detective whispered, his voice trembling. "He completely believes it to be true."

 

For the next two hours, Izuku unburdened his soul.

 

He started from the very beginning. He looked All Might dead in the eye and spoke of the afternoon they met on the rooftop, and the crushing despair of having his dream shattered. All Might flinched, a look of profound guilt crossing his skeletal face as he realized his words had driven the boy into that dark alleyway.

 

Izuku detailed the spatial rift. He described the dying, pale-skinned alien named Isshiki Ōtsutsuki. He explained the terrifying ocular jutsu, the crushing gravity, and the forceful implantation of the Karma mark before the alien’s body turned to ash.

 

"He told me I was empty," Izuku whispered, tears finally welling in his green eyes. "He said because I didn't have a Quirk Factor, my body had no internal defenses. I was a perfect vessel."

 

The adults were paralyzed. Nezu’s tea had gone completely cold. All Might was gripping the armrest of his chair so hard the wood was splintering.

 

"The Karma is slowly rewriting my DNA," Izuku continued, his voice tight. "It's extracting his genetic code into my body. Once it reaches one hundred percent, my soul will be erased, and Isshiki Ōtsutsuki will resurrect in my body. Right now... the extraction is at fifty percent."

 

"My god," All Might choked out, a rare cough of blood staining his chin. "Young Midoriya... you've been carrying this entirely on your own? For nearly a year?"

 

"I had to," Izuku said. "If I told anyone, I would have been locked up, or experimented on. But I can't hide it anymore. At the U.S.J., I was about to die, and so were my friends. I made a deal with him. I let him out for thirty seconds. He summoned the black cube. He dismantled the Nomu. If I hadn't forcefully taken control back, he would have killed everyone in the dome, including you, All Might."

 

Aizawa’s good eye was wide, staring at the boy. The coldness he had sensed in the boy’s fighting style, the ruthless efficiency, the terrifying aura—it wasn't a traumatized teenager. It was an alien warlord bleeding through the cracks of a boy's soul.

 

"And what happens if he resurrects?" Nezu asked, his voice deathly quiet. "What is his objective?"

 

Izuku swallowed hard. "He plans to plant a creature called a Ten-Tails. Its roots will burrow into the Earth's core. It will absorb the planet's oceans, the land, and the Quirk Factors of every living human until the planet is a dead rock. It will cultivate a Chakra Fruit, which he will consume to evolve. It's planetary genocide."

 

The room fell into an abyss of silence. Tsukauchi leaned against the wall, his face devoid of color.

 

"True," Tsukauchi breathed out, his voice cracking. "Every... every single word. No lies."

 

The sheer cosmic horror of the revelation hung in the air like a guillotine. They were Pro Heroes. They fought bank robbers, serial killers, and terrorists. They were utterly unequipped to comprehend an interdimensional entity that farmed planets for energy.

 

"During the Sports Festival," Izuku said, breaking the silence. "He tried to take over again to kill Todoroki. We fought... inside my mind. I managed to suppress him. I took his chakra and purified it with my own will. That's why the Karma turned blue. I can control the power now, but it's only temporary. The extraction is still happening. If my body weakens, if my willpower breaks, he will take over."

 

Izuku stood up from his chair. He bowed deeply, a perfect ninety-degree angle, his head facing the floor.

 

"I am a ticking time bomb," Izuku said, his tears hitting the carpet. "I wanted to be a hero more than anything in the world. But if letting me live means the destruction of the Earth... then you have to kill me. Before he reaches one hundred percent. Please... before I lose myself completely."

 

 

"Lift your head, Midoriya."

 

The voice was raspy, exhausted, but filled with an uncompromising, iron resolve.

 

Izuku slowly stood up straight, wiping his eyes. Aizawa walked around the desk, his heavily bandaged form moving stiffly. He stopped mere inches from Izuku. The underground hero looked down at his student, seeing not an apocalyptic threat, but a terrified fifteen-year-old boy who had willingly endured hell to protect a world that had outcast him.

 

Without a word, Aizawa placed his uninjured hand on top of Izuku’s messy green hair.

 

Izuku’s breath hitched. He had expected handcuffs. He had expected to be hauled away to Tartarus.

 

"You are a child," Aizawa said softly. "You were targeted by a monster, violated, and burdened with the fate of the world. And yet, you stood in that stadium and smiled to save your classmate. You are more of a hero than half the pros in this city."

 

Aizawa dropped his hand and looked Izuku in the eye.

 

"We are not going to lock you up, Midoriya. And we are certainly not going to kill a hero in training who hasn't given up the fight."

 

"But Mr. Aizawa," Izuku protested, his voice breaking. "If he takes over—"

 

"If he takes over, I will stop him," Aizawa interrupted. "My Quirk, Erasure. It pauses the biological Quirk Factors of those I look at. If this 'Karma' relies on a biological neural network to function within your body, my Erasure will halt the chakra flow. It will paralyze the alien."

 

Aizawa knelt down slightly, meeting Izuku at eye level. His expression was a mask of grim, absolute determination.

 

"Here is my vow to you, Izuku Midoriya," Aizawa said, his voice echoing with the weight of a blood oath. "You will stay at U.A. You will continue to train. You will fight to suppress this parasite, and we will help you build the physical and mental fortitude to halt the extraction. But... if the day comes where you lose the battle. If Isshiki Ōtsutsuki takes the wheel and your soul is gone..."

 

Aizawa’s visible eye hardened.

 

"I will use my Erasure to paralyze his power. And I will kill you myself. I will end it quickly, and I will not let him use your body to harm the people you love. You do not have to carry the fear of becoming a monster anymore. I will carry that burden for you."

 

Izuku stared at his homeroom teacher. The sheer magnitude of the offer—the horrific, beautiful mercy of it—shattered the last of Izuku's emotional walls. Aizawa was offering to be his executioner so that Izuku could live the rest of his life free from the terror of his own demise.

 

Izuku lunged forward, burying his face in Aizawa’s chest, sobbing uncontrollably. Aizawa stiffened for a moment, unaccustomed to such open displays of emotion, but slowly wrapped his good arm around the boy, holding him tight.

 

"I'm sorry," All Might wept from his chair, burying his face in his skeletal hands. "I am so sorry, my boy. I left you alone on that roof. This is my fault."

 

"No," Nezu said firmly, standing up on his chair. "Blame helps no one, Toshinori. What matters is the future. Midoriya has proven that the Karma can be subjugated. The blue markings indicate that the host's willpower can overwrite the parasite's data. If we forge Midoriya’s body and spirit to an unbreakable state, we can indefinitely stall the extraction at fifty percent."

 

Nezu looked at Tsukauchi. "Detective, this information does not leave this room. The Hero Public Safety Commission cannot know. They would view Midoriya as a weapon or a threat and demand his termination. This is a U.A. secret now."

 

Tsukauchi nodded solemnly. "Agreed. My lips are sealed."

 

"Excellent," Nezu said, his black eyes gleaming with a newfound, fierce determination. "Midoriya, your curriculum is going to change. You will still attend standard classes, but your physical and mental conditioning will be overseen privately by myself, Aizawa, and All Might. We are going to teach you how to turn the power of a god into the ultimate shield for humanity."

 

Izuku pulled away from Aizawa, wiping his nose, a brilliant, determined light returning to his emerald eyes. He looked at his left hand, at the black diamond that no longer felt like a death sentence, but a challenge.

 

"I won't let him win," Izuku declared, his voice steady. "I promise."

 

 

Miles away, in the dark, subterranean depths of Kamino Ward, a very different kind of meeting was taking place.

 

The room was lit only by the faint, eerie glow of medical monitors. Tubes carrying blood and life-sustaining fluids snaked across the floor, connecting to a massive life-support chair. Seated in the chair was a man with a face made of scarred, featureless scar tissue. He had no eyes, no nose, only a mouth that curled into a permanent, chilling smile.

 

All For One, the Demon King of the underground, sat perfectly still.

 

In front of him, a massive television screen was playing a muted recording of the U.A. Sports Festival. It was looped to the exact moment Izuku Midoriya's Karma turned blue, followed by the boy dodging Shoto Todoroki's ice and delivering the shockwave kick.

 

Standing nearby, a man in a tailored suit, Kurogiri, wiped down a glass at the makeshift bar. "Master," Kurogiri said cautiously. "Tomura is still recovering from his temper tantrum. He is obsessed with that boy. He insists the boy cheated at the U.S.J."

 

"Tomura's vision is clouded by his immaturity," All For One said, his voice smooth, cultured, and dripping with sinister authority. "He looks at the boy and sees an obstacle. I look at the boy, and I see a miracle."

 

All For One leaned forward, the tubes attached to his neck hissing. He lacked eyes, but his sensory Quirks—infrared vision, air vibration detection, and spatial mapping—allowed him to "see" the footage with more clarity than a normal human.

 

"Look at the boy's left hand, Kurogiri," All For One instructed. "When he shatters the ice, he does not emit a kinetic blast. He does not manipulate temperature. The mass of the ice simply ceases to exist in its macro state. He is shrinking the molecular bonds of matter instantly."

 

"A powerful spatial Quirk," Kurogiri offered.

 

"No," All For One corrected, his smile widening. "That is what is so fascinating. It is not a Quirk."

 

Kurogiri paused his wiping. "Master? I don't understand."

 

"My Quirk, All For One, allows me to sense the Quirk Factors within other human beings. It is a biological resonance. When I observe a Quirk, the Vestiges within me react. They recognize a kindred mutation. But when I observe this Izuku Midoriya... the Vestiges are silent. They are utterly terrified."

 

All For One raised a scarred hand, tracing the air as if he could feel Izuku's aura through the screen.

 

"He possesses no Quirk Factor. The power he is wielding operates on a frequency completely alien to this planet's biology. It is a fundamental bending of reality, fueled by an energy source that I cannot identify. And that blue transformation... the sheer density of the power output defies the laws of thermodynamics."

 

All For One chuckled, a deep, vibrating sound that made the medical equipment rattle. For over a century, his ultimate goal had been to reclaim One For All and subjugate society. But watching the green-haired boy on the screen, a new, infinitely more ambitious greed took root in his dark soul.

 

"One For All is a powerful tool," All For One mused, steepling his fingers. "But it is still a human power. What that boy possesses... it is the power of a deity. A reality-altering engine housed within a mortal shell."

 

"What are your orders, Master?" Kurogiri asked.

 

"Tell Tomura to leave the boy alone. He is not to be killed," All For One commanded, his tone brokering no argument. "Let the boy train. Let him cultivate this alien power. When the time is right, I will not steal his Quirk. I will take his body entirely. I will transfer my consciousness into Izuku Midoriya, and I will become a true god."

 

 

Far beyond the borders of Kamino Ward, beyond the stratosphere of Earth, and beyond the very fabric of the known universe, lay the deep, swirling void of the space-time continuum.

 

In a dimension completely devoid of stars, a massive, ancient structure floated in the endless white ether. It was an Ōtsutsuki Shrine, a colossal monument built of pale, smooth stone, adorned with towering pillars and intricate, geometric carvings.

 

Deep within the shrine was a chamber containing a series of stone panels, arranged in pairs. These panels represented the members of the Ōtsutsuki clan who had been dispatched across the multiverse to harvest Chakra Fruits.

 

A figure floated into the chamber. He was pale, clad in elegant white robes, with long, stark white hair and two curving horns protruding from his head. In his palm was a glowing red Rinnegan.

 

Momoshiki Ōtsutsuki scoffed as he looked at a particular pair of panels. One panel depicted Kaguya Ōtsutsuki, and the other depicted Isshiki.

 

"Pathetic," Momoshiki sneered.

 

Behind him, a hulking, imposing figure with a glowing red battle-axe materialized. Kinshiki Ōtsutsuki bowed his head. "Lord Momoshiki. You called for me?"

 

"I was merely observing the remnants of our disgraced kin," Momoshiki said, floating closer to the panels. "Kaguya betrayed the clan and was sealed by the primitive apes of her assigned sector. And Isshiki... he vanished entirely. His chakra signature was extinguished months ago. I assumed he was killed by his own vessel, or consumed by the Ten-Tails."

 

"Shall we report his sector as a failure to the clan elders?" Kinshiki asked.

 

Momoshiki reached out to touch Isshiki's stone panel. As his pale fingers grazed the stone, something entirely unexpected happened.

 

The panel did not remain cold and dormant. It suddenly pulsed.

 

A jagged crack formed down the center of the stone. From the crack, a faint, glowing light emerged. But it was not the menacing, crimson-red light of an Ōtsutsuki's Karma.

 

It was a brilliant, defiant, sapphire blue.

 

Momoshiki pulled his hand back, his Byakugan eyes widening in sheer, unadulterated shock.

 

"What is this?" Momoshiki whispered.

 

"Lord Momoshiki!" Kinshiki gasped, sensing the shift in the multiverse's energy. "A signal... Isshiki's Karma signature has re-emerged! But it is not coming from his assigned sector. It is broadcasting from an entirely uncharted dimension!"

 

Momoshiki stared at the blue light radiating from the panel. The light felt wrong. It lacked the cold, predatory perfection of the Ōtsutsuki. It felt warm. It felt chaotic. It felt... human.

 

"He is not dead," Momoshiki deduced, his eyes narrowing in disgust. "He performed an emergency dimensional leap and implanted his Karma into a lifeform in an unknown universe. But the extraction process... it is corrupted. The vessel's primitive DNA is actively fighting back. It is mutating the Karma."

 

"An inferior creature is suppressing the will of an Ōtsutsuki?" Kinshiki growled, gripping his axe tightly. "Such heresy cannot be permitted to exist. It insults the clan."

 

Momoshiki lowered his hand, a cruel, haughty smirk replacing his shock. The mystery intrigued him. An unknown dimension with a creature capable of subjugating a god’s power? It was a prize waiting to be claimed.

 

"Calm yourself, Kinshiki," Momoshiki said, turning his back on the glowing blue panel. "Isshiki was always a brute. If he allowed himself to be chained by a monkey, he deserves his fate. Let the anomaly cultivate the power. We have other worlds to harvest first. But eventually... we will pay this uncharted dimension a visit. I wish to see the face of the mortal who thinks he can tame the power of the gods."

 

Momoshiki and Kinshiki vanished from the shrine, leaving the blue light to pulse quietly in the dark, a beacon echoing across the multiverse.

 

 

The night air in Musutafu was cool and refreshing. The U.A. Heights Alliance dormitories were quiet, the exhausted students of Class 1-A having long since gone to sleep after the grueling events of the Sports Festival.

 

But Izuku Midoriya was not asleep.

 

He stood on the roof of the dormitory building, dressed in a simple black tank top and sweatpants, looking out over the sprawling, neon-lit cityscape. The wind ruffled his green hair.

 

He closed his eyes and looked inward.

 

Deep within his mindscape, the endless white void was no longer an oppressive, sterile domain. It was shifting, taking on the warm, golden hues of a sunset. In the center of the space, bound by massive, glowing green and blue chains of pure spiritual energy, sat Isshiki Ōtsutsuki.

 

The alien god was silent, his golden eye glaring at Izuku with a hatred so profound it could boil oceans. But for now, he could not move. The host had asserted dominance.

 

You can glare all you want, Izuku thought, his mental voice calm and unyielding. But I am not your vessel anymore. I am your warden.

 

Isshiki didn't speak. He merely closed his eyes, settling in for a war of attrition that would last a lifetime.

 

Izuku opened his eyes and returned to the physical world. He raised his left hand toward the sky. He focused his mind, channeling his own heroic resolve, his own desire to protect, into the alien circuitry embedded in his flesh.

 

Slowly, the pitch-black diamond in his palm began to glow.

 

The light was not the red of a conqueror. It was a radiant, beautiful sapphire blue. The geometric lines crawled up his forearm, gently illuminating the darkness of the rooftop, pulsing in sync with the beating of his own human heart.

 

He felt the power—the spatial manipulation, the kinetic augmentation, the sensory mastery—flow through his veins. But it no longer felt like a violation. It felt like a tool. A sword forged in the fires of hell, now wielded by an angel.

 

Izuku looked past the city skyline, up into the vast, infinite expanse of the starry night sky.

 

Somewhere out there, beyond the stars, beyond the dimensions, there were monsters. There were entities that looked at humanity and saw nothing but dirt and fertilizer. There were gods of apathy and destruction.

 

And somewhere down below, in the dark underbelly of the city, villains plotted to tear society apart for their own selfish desires.

 

Let them come.

 

Izuku clenched his left fist, the blue Karma flaring brightly, leaving a trail of luminous blue energy in the air. He was no longer just a Quirkless boy dreaming of being a hero. He was no longer a victim of a cruel universe.

 

He was Izuku Midoriya. He was the disciple of All Might, the student of Shota Aizawa, and the friend of Class 1-A.

 

He was the boy who had stolen the fire of a god.

 

And he would burn down the heavens themselves to protect his world.
