What If Deku Had the Nine-Tails Sealed Inside Him

 

The plastic All Might action figure slipped from four-year-old Izuku Midoriya’s hand, clattering against the linoleum floor of the doctor’s office. The sound echoed in the small, sterile room, heavy with a suffocating finality.

 

"You should probably give it up," the doctor said, leaning back in his swivel chair. His voice was clinical, devoid of the world-shattering empathy required for the words he had just spoken. He tapped a pen against the glowing X-ray pinned to the lightboard—an image of Izuku’s small, fragile foot. "It's right here. You see this extra joint in the pinky toe? It's the universal marker. The evolution of Quirks streamlined the human body. Missing that joint means you're part of the next stage of human evolution. Having it… well, it means you're tethered to the past. You have no Quirk, kid."

 

Izuku stared at the floor, his large green eyes trembling with unshed tears. Beside him, his mother, Inko, gasped, her hands flying to her mouth. "But… but doctor, my husband breathes fire! I can pull small objects! Surely there’s a mistake. A late bloomer, perhaps?"

 

"Science doesn't make those kinds of mistakes, Mrs. Midoriya," the doctor sighed, clearly wanting to move on to his next appointment. "Your son is Quirkless. He will never develop a power. I'm sorry."

 

The ride home was a blur of gray skies and deafening silence. Izuku didn't speak. He didn't ask to stop for ice cream. He just sat in his car seat, staring out the window at a world filled with heroes he could never join. That evening, he sat in the dark of his bedroom, watching the same viral video of All Might's debut he had watched a thousand times. The hero's booming laugh, his fearless smile amidst the burning wreckage—it all felt like a cruel joke now.

 

When Inko came in, weeping, apologizing over and over as she held him, Izuku felt his heart completely shatter. He didn't want an apology. He wanted her to tell him he could still do it.

 

Exhausted by grief, the four-year-old boy finally cried himself to sleep.

 

 

 

Drip.

 

Drip.

 

Splash.

 

Izuku blinked, his eyelashes heavy. He wasn't in his bed anymore. The comforting smell of his All Might bedsheets was gone, replaced by the pungent, metallic scent of rust, moss, and stale water. He sat up, his small hands splashing into calf-deep water that was surprisingly warm.

 

He looked around. He was in a massive, cavernous corridor that looked like an ancient sewer system. The walls were made of slick, dark stone, lined with rusted pipes that hummed with a strange, thrumming energy. The lighting was practically non-existent, save for an eerie, ambient red glow pulsing from the end of the hall.

 

"Mom?" Izuku called out. His voice echoed, sounding impossibly small in the vast expanse.

 

He stood up, his oversized pajama shirt clinging to his wet legs. He wasn't scared, oddly enough. He was a boy obsessed with heroes and adventures; maybe this was a dream about exploring a villain's secret lair! Gathering his courage, he waded through the water, following the red light.

 

The corridor opened up into a chamber so colossal it defied comprehension. The ceiling vanished into darkness. But what caught Izuku's attention wasn't the size of the room—it was what stood in the center of it.

 

Gigantic, golden iron bars stretched from the floor to the unseen ceiling, forming a massive cage. The center of the cage bore a thick paper tag with a single kanji character: Seal.

 

From the darkness behind the bars, a low, rumbling growl vibrated through the water, rattling Izuku’s teeth. Suddenly, two enormous, slit-pupiled crimson eyes snapped open. They were the size of houses, glowing with a terrifying, ancient malice.

 

"So," a voice boomed, deep and resonant, like grinding tectonic plates. "My new jailer has finally come to gloat. And it is a pathetic, sniveling infant."

 

From the shadows, a colossal snout emerged, followed by the terrifying visage of a demonic fox. Rows of teeth, each the size of a skyscraper, curled into a sneer. Behind the creature, nine massive tails swished lazily, stirring the water outside the cage into a turbulent tide.

 

Any normal child would have died of fright. But Izuku, fresh off a devastating medical diagnosis and desperate for any sign of abnormality, gasped. His eyes widened into saucers, literally sparkling with stars.

 

"A-Are you my Quirk?!" Izuku shouted, splashing forward until he was right at the edge of the bars, craning his neck up. "The doctor said I didn't have one! But he was wrong! I have a giant puppy Quirk!"

 

The Nine-Tails blinked. The sheer, unadulterated disrespect of being called a 'giant puppy' momentarily stalled the demon's ancient rage.

 

"I am not a 'Quirk', you ignorant whelp," Kurama snarled, slamming a massive, clawed paw against the bars. The resulting shockwave blew Izuku backward, sending him tumbling through the water. "I am the Nine-Tailed Fox! A being of pure, unadulterated chakra! The terror of the elemental nations! And I am trapped inside a weak, fragile meat-sack!"

 

Izuku sat up, rubbing his head, looking completely unfazed. "Chakra? Like… energy? Can you shoot lasers? Can you make me super strong? Oh! What's your name? I'm Izuku Midoriya!"

 

Kurama growled, smoke billowing from his nostrils. It had been centuries since he was sealed away by that ancient mystic, his essence tied to a dormant bloodline. Generations had passed with the seal inactive, but for some miserable reason, it had awakened in this boy. The beast could sense the outside world through Izuku's senses. He had seen the doctor's visit. He knew this world had evolved to possess innate magics they called 'Quirks', while chakra had long been forgotten.

 

"Listen to me, brat," Kurama hissed, leaning closer to the bars. "I am not your power. I am a prisoner. If you annoy me, I will tear your soul to shreds from the inside out. Now go away and let me sleep. I have no interest in your petty mortal ambitions."

 

The giant fox retreated into the shadows of the cage, the giant red eyes sliding shut.

 

"Wait! Don't go!" Izuku yelled, splashing at the bars. "Please! I want to be a hero!"

 

There was no answer. Just the steady drip, drip, drip of the mindscape.

 

Izuku woke up in his bed with a gasp, his pajamas dry. He ran to the mirror, checking his teeth, his eyes, hoping to see a fox's ears or a tail. Nothing. He was just plain, ordinary Izuku.

 

He told his mother about the giant fox in his dreams. Inko smiled sadly, patting his head, believing it was just an imaginary friend his mind had created to cope with the trauma of being Quirkless. Even Izuku began to believe it was just a dream. He tried talking to the fox when he closed his eyes, but he never returned to the sewer.

 

The fox ignored him for an entire decade.

 

 

 

Growing up Quirkless in a society where eighty percent of the population possessed superhuman abilities was akin to being born with a target painted on your back. And the person with the best aim was Katsuki Bakugo.

 

"You're worse than the rest of these damn rejects, Deku!" Bakugo sneered, slamming his hands onto Izuku's desk. A small explosion popped from his palms, singing the wood and leaving behind the smell of burnt caramel and ozone. "You're completely Quirkless. You really think you can stand in the same ring as me?"

 

Fourteen-year-old Izuku flinched, pulling his hero analysis notebook to his chest. "I-I'm not trying to compete with you, Kacchan! It's just… it's always been my dream. There's no harm in trying, right?"

 

"There is when you're a stepping stone!" Bakugo roared, snatching the notebook from Izuku's grip. He blasted it between his palms, charring the cover, before casually tossing it out the third-floor window.

 

Izuku let out a strangled squeak, watching his life's work fall into the koi pond below.

 

Bakugo turned, his lackeys snickering behind him. "If you want a Quirk so badly, there might be a way. Take a swan dive off the roof and pray you'll be born with a Quirk in your next life!"

 

The words felt like a physical blow. Izuku froze, his eyes locked onto the floor as Bakugo and his followers sauntered out of the classroom. Once they were gone, the silence of the empty room pressed down on him. He slowly walked down to the courtyard, retrieving his soggy, ruined notebook from the mouths of the hungry koi fish.

 

"Stupid," Izuku whispered, tears pricking his eyes. "Stupid, stupid."

 

He rolled up his sleeve. His forearm was mottled with faint bruises and a slight burn from Bakugo's earlier 'warning' taps. But as Izuku watched, a strange phenomenon occurred. A microscopic wisp of faint, red mist curled around his skin. It was so faint it was practically invisible in the sunlight. A pleasant, buzzing warmth sank into his muscles. Within seconds, the burn faded into a pale pink scar, and the ache in his bones vanished.

 

Izuku sighed. My 'Healing Quirk'.

 

Over the years, Izuku had noticed he never stayed hurt for long. Broken fingers from a bully's kick would heal overnight. Burns would vanish in hours. He had tried to tell the doctors, tried to show his mother, but the healing only ever happened when his body was in dire need, and it was entirely passive. Without a Quirk factor or a missing toe-joint, the doctors wrote it off as an exceptionally fast natural metabolism.

 

Deep down, Izuku wondered if the giant fox from his childhood dream was real, and if this was its doing. But he had long stopped trying to reach the sewer in his mind.

 

Deep within that very mindscape, behind the golden bars, Kurama rested his chin on his massive paws and scoffed.

 

"Pathetic," the fox rumbled to himself. "Letting a spiky-haired brat push you around. If I wasn't sealed to your life force, I'd let you bleed out just to spare myself the embarrassment. But if you die, I die. Consider yourself lucky, meat-sack."

 

Kurama hated this era. He hated the noise of the modern world, he hated the lack of respect for ancient power, and most of all, he hated Izuku's incessant crying. But self-preservation was paramount. The fox doled out just enough of his chakra to knit the boy's flesh back together, keeping his vessel intact. Nothing more.

 

Oblivious to the ancient demon grumbling in his subconscious, Izuku walked home, taking the route under the overpass. The shadows of the bridge provided a brief respite from the glaring afternoon sun.

 

He pumped his fist, trying to force a smile. "I'll just keep trying! I can't let Kacchan get to me! I'll go home, rewrite my notes, and—"

 

A strange gurgling sound echoed from the manhole cover behind him.

 

Izuku turned just in time to see a massive, towering wave of dark green, foul-smelling sludge erupt from the grate. The sludge writhed and twisted, forming a vaguely humanoid shape with two massive, unhinged eyes and a jagged mouth.

 

"A medium-sized invisibility cloak," the Sludge Villain hissed, his voice wet and garbled. "Perfect."

 

Before Izuku could scream, the villain lunged. Heavy, suffocating liquid slammed into Izuku, wrapping around his arms, his legs, his torso. A thick tendril of sludge forced its way into Izuku's mouth and up his nose.

 

The panic was instantaneous and absolute. Izuku clawed wildly at the sludge covering his face, his fingernails scraping against the fluid to no avail. His lungs burned. The villain was forcing himself down Izuku's throat, trying to hollow him out like a meat-suit.

 

"Don't worry, kid," the villain laughed, the sound vibrating through the sludge directly into Izuku's ears. "It'll only hurt for about forty-five seconds. Then it'll all be over."

 

Izuku's vision began to spot with black. His limbs grew heavy. I'm dying, he thought, tears mixing with the foul liquid. I'm really dying. Somebody... anybody... save me...

 

Deep within the mindscape, the water suddenly began to boil.

 

Kurama's eyes snapped open. The oppressive, suffocating feeling of the Sludge Villain was bleeding into the mental plane. The air in the sewer grew thin.

 

"This idiot is actually going to die," Kurama roared, standing to his full, towering height. His tails whipped the water into a frenzy. "I survived the Sage of Six Paths, I survived Madara Uchiha, I am NOT dying in a sewer because of a pile of sentient mud!"

 

Kurama stepped up to the gates. He couldn't break the seal, but in moments of extreme physical duress, the barrier thinned. The fox drew upon a fraction of his dark, dense, malevolent chakra and violently shoved it through the bars, forcing it directly into Izuku's failing nervous system.

 

Back in the real world, Izuku’s body suddenly convulsed.

 

The Sludge Villain paused. "Huh? What the—"

 

Izuku's eyes snapped open. The bright, innocent emerald green was gone, replaced by a terrifying, glowing, slit-pupiled crimson. His fingernails elongated into sharp, jagged claws. A sudden, violent burst of dense, bubbling red energy erupted from Izuku's pores, superheating the air around them.

 

The sludge touching Izuku's skin began to sizzle and boil.

 

"GAAAAH!" The Sludge Villain shrieked, recoiling as the red aura burned him like acid. "What the hell is this?! It burns! You're burning me!"

 

Driven purely by instinct and the foreign, feral rage pumping through his veins, Izuku swung his arm. His clawed hand, enveloped in a thick layer of red chakra, tore through the sludge like a hot knife through butter, ripping a massive chunk of the villain's mass away. Izuku gasped for air, coughing violently as the red aura around him flickered dangerously.

 

Before the villain could retaliate or Izuku could lose control to the demon's wrath, the manhole cover blew clean off its hinges with a resounding CLANG.

 

A massive, muscular figure burst from the sewers, clad in a white t-shirt and cargo pants. Golden hair stood up in two prominent tufts.

 

"Fear not, young man!" a booming, legendary voice echoed through the tunnel. "For I am here!"

 

Izuku's crimson eyes widened, fading instantly back to green as the red chakra receded, pulling back into his core. All... Might?

 

"TEXAS SMASH!"

 

All Might threw a devastating punch. He didn't even make contact with the villain, but the sheer wind pressure generated by his fist created a localized tornado. The Sludge Villain was instantly blown apart, scattered into hundreds of splattering pieces against the tunnel walls.

 

The wind knocked Izuku backward. Exhausted, suffocated, and reeling from the sudden, violent surge of foreign energy that had just coursed through him, Izuku's eyes rolled back in his head. He passed out, the last thing he saw being the towering silhouette of the Symbol of Peace.

 

 

 

"Hey! Wake up! Thought we lost you there!"

 

Izuku’s eyes fluttered open. He was met with a pair of massive, shadowed eyes staring down at him. He screamed, scrambling backward until his back hit the tunnel wall.

 

All Might laughed heartily. "Glad to see you're okay! Apologies for getting you caught up in my villain hunt. I usually don't make mistakes like this, but I'm in a new city!"

 

Izuku stared, his jaw unhinged. The number one hero. The man he had idolized since he could comprehend what a hero was, was standing right in front of him.

 

"I—I need an autograph!" Izuku scrambled, frantically searching around. He found his damp, burnt notebook lying on the ground. He flipped it open to a blank page. "Please, sign my—HE ALREADY DID IT!"

 

A massive, sprawling signature took up two entire pages. Izuku bowed repeatedly, bowing so fast he looked like a blurry metronome. "Thank you! Thank you! It's a family heirloom! I'll pass it down for generations!"

 

"Right, well!" All Might gave a thumbs up, turning to a couple of soda bottles filled with the captured green sludge. "I must be off! I need to deliver this fellow to the authorities."

 

"Wait!" Izuku panicked. "Already? But I have so many questions!"

 

"A hero is constantly fighting time as well as enemies!" All Might declared, bending his knees. He prepared to leap.

 

No, Izuku thought. I can't let him leave. I need to know. I need to know if I can do it.

 

Driven by desperation, Izuku lunged forward right as All Might launched into the air. The sheer force of the jump tore them from the ground, soaring hundreds of feet into the sky.

 

"Hey, hey, hey!" All Might yelled, feeling the extra weight on his leg. He looked down in horror. "Kid, let go! This is too much!"

 

"If I let go now, I'll die!" Izuku screamed, his cheeks flapping violently in the wind pressure.

 

"Good point!"

 

All Might scanned the area and angled his descent toward a tall, flat-roofed office building. They landed with a heavy thud. Izuku immediately collapsed onto the concrete, gasping for air, his heart hammering against his ribs.

 

"That was incredibly reckless!" All Might scolded, though he suddenly coughed, bringing a hand to his mouth. "You could have been killed. Now, knock on the access door. I'm sure someone will let you down. I have to go."

 

"Wait, please!" Izuku squeezed his eyes shut, his fists clenching at his sides. This was it. The moment of truth. "I have to know!"

 

All Might stopped, his back turned to the boy. Steam began to slowly rise from the hero's muscular frame.

 

"Even without a Quirk!" Izuku yelled, his voice cracking with years of pent-up emotion. "Even if everyone tells me I'm useless! Even if I don't have a power... can I still be a hero? Can someone without a Quirk be like you?!"

 

Izuku waited. He waited for the booming laugh. He waited for the validation he had craved his entire life.

 

Instead, a cloud of thick smoke erupted, obscuring All Might. When the wind cleared the smoke away, the towering, muscular god of justice was gone. In his place stood a skeletal, emaciated man in baggy clothes, coughing up blood.

 

Izuku screamed. "What happened?! You deflated! Are you a fake?!"

 

The man wiped blood from his chin, sighing heavily. "I am All Might." He sat down against the railing, lifting his loose shirt to reveal a horrifying, jagged purple scar that covered half his torso. It looked like a starburst of mangled flesh.

 

"Five years ago, a villain did this to me," All Might explained, his voice quiet, stripped of its usual bombast. "My respiratory system was nearly destroyed. I lost my whole stomach. After countless surgeries, I can only do hero work for about three hours a day. The rest of the time, I look like this."

 

Izuku was horrified. "Five years ago... was it the Toxic Chainsaw fight?"

 

"You know your stuff, kid, but no. That punk couldn't scratch me. This fight was kept out of the papers. The Symbol of Peace cannot be seen to be vulnerable." All Might looked at Izuku, his sunken eyes heavy with sorrow. "You asked if you can be a hero without a Quirk. Pro heroes are always putting their lives on the line. Some villains simply cannot be beaten without power. So, no. I honestly don't think you can become a hero without a Quirk."

 

The words dropped like a lead weight in the silence of the rooftop.

 

"If you want to help people, become a police officer," All Might said softly, walking over to the access door and opening it. "They get mocked, but it's a fine profession. It's not bad to dream, young man. But you have to make sure your dreams are realistic."

 

The door clicked shut. Izuku was alone.

 

He didn't cry. The pain was too deep for tears. It was a hollow, empty void in his chest. The number one hero—the man who smiled through everything—had just looked him in the eye and told him he was worthless.

 

Deep within his psyche, however, the reaction was vastly different.

 

The water in the mindscape bubbled furiously. Kurama paced back and forth behind his golden bars, his massive claws gouging deep trenches into the stone floor. The fox wasn't angry for Izuku's sake. He didn't care about the boy's crushed dreams.

 

But Kurama’s pride was absolute.

 

"That skeletal, half-dead weakling," Kurama snarled, his chakra flaring hot and bright. "He dares to look down on my vessel? He dares to say a host of the Nine-Tailed Fox is powerless? The audacity! The sheer, unmitigated arrogance of these modern mortals!"

 

Kurama hated Izuku, yes. But Izuku was his property. His jailer. And no one insulted the Nine-Tails by proxy.

 

Izuku slowly walked down the stairwell, his mind a blank slate. He stepped out onto the street, his feet moving on autopilot. He didn't know where he was going. He didn't care. The notebook in his hand felt like a heavy block of lead, a monument to his own stupidity.

 

I should just give up, Izuku thought, his eyes dead. Kacchan was right. I'm just a stepping stone.

 

A massive explosion shattered his thoughts.

 

Izuku blinked, looking up. He had wandered into a shopping district. Plumes of black smoke were rising into the sky just a few blocks away. The smell of burning rubber and ozone filled the air. A crowd had gathered, kept back by a police barricade.

 

Curiosity—or perhaps a lingering, masochistic desire to see heroes at work—drew him forward. He pushed his way to the front of the crowd.

 

His breath hitched.

 

The alleyway was a warzone. Fires raged out of control. And in the center of the destruction was the Sludge Villain. The bottles must have fallen out of All Might's pocket when Izuku grabbed him. This was his fault.

 

Several pro heroes were on the scene—Death Arms, Kamui Woods, Mt. Lady, Backdraft—but none of them were engaging.

 

"I can't get close! My wood will catch fire!" Kamui Woods yelled.

 

"I need a two-lane road to get back there!" Mt. Lady complained.

 

"We just have to wait for someone with a suitable Quirk!" Death Arms grunted, shielding his face from the intense heat.

 

Izuku gripped the barricade, guilt gnawing at his insides. This is my fault. I distracted All Might. Now someone is going to pay the price.

 

He looked closer at the villain. The sludge was thrashing wildly, trying to consume a hostage. The hostage was fighting back fiercely, firing massive explosions from his palms, which only fueled the fires around them.

 

Then, the sludge shifted, revealing the hostage's face for a split second.

 

Fierce, terrified crimson eyes met Izuku's.

 

Kacchan.

 

Before Izuku's brain could process the danger, before he could remember that he was Quirkless, before he could recall All Might's crushing words, his legs moved.

 

He vaulted the police barricade and sprinted full-tilt into the blazing alleyway.

 

"Hey, kid! Stop! You'll get yourself killed!" Death Arms roared.

 

Izuku didn't stop. He couldn't. His mind was screaming at him to turn back, but his body wouldn't listen. He saw the terror in his childhood tormentor's eyes. Bakugo was suffocating, just like Izuku had been.

 

The Sludge Villain noticed him. "You again! I'll deal with you once and for all!"

 

A massive tendril of sludge whipped toward Izuku like a scythe.

 

In the mindscape, Kurama stopped pacing. He looked through Izuku's eyes at the approaching death. The boy was throwing his life away for the brat who had bullied him. It was illogical. It was stupid. It was exactly the kind of reckless, self-sacrificing idiocy that vaguely reminded the ancient demon of a certain blonde ninja from centuries past.

 

"Idiot," Kurama grunted. "Don't you dare die before you've mastered my power."

 

Kurama flicked his tail. A microscopic needle of pure, concentrated red chakra shot up through the seal, flooding into Izuku's legs and right arm.

 

Outside, Izuku felt a sudden, explosive surge of heat. The world seemed to slow down. The red mist that usually healed him flared to life, not as a gentle healer, but as a violent, crackling aura. It vanished almost as quickly as it appeared, but in that fraction of a second, Izuku's speed tripled.

 

He slid under the sweeping tendril of sludge, the concrete cracking under his sneakers. He ripped his ruined yellow backpack off his shoulders and, fueled by that momentary burst of demonic strength, hurled it like a cannonball.

 

The heavy metal zipper of the backpack struck the Sludge Villain directly in his unblinking eye.

 

"GRAAAAAH!" The villain shrieked, his grip loosening in pain.

 

Bakugo's mouth broke free from the sludge, allowing him to gasp for a desperately needed breath of air. He looked down, stunned, at the boy who had just saved him. "Deku?! What the hell are you doing?!"

 

"I don't know!" Izuku cried, his hands desperately clawing at the sludge, trying to dig Bakugo out. The red aura was gone, leaving his muscles screaming in protest. "My legs just moved on their own! You looked like you needed saving, Kacchan!"

 

Bakugo's eyes widened.

 

The Sludge Villain recovered, towering over them with murderous intent. "I'm going to crush you both!"

 

Izuku threw his arms up, ready to shield Bakugo with his own body. He braced for the impact, closing his eyes.

 

A hand grabbed his shoulder.

 

"I really am pathetic," a voice muttered.

 

Izuku opened his eyes. All Might was standing in front of him, having pushed past his limits, his muscular form rippling with steam and power. Blood trickled from his mouth, but his eyes burned with an indomitable blue fire.

 

"I told you the traits to make a great champion," All Might roared, grabbing Bakugo's arm and tearing him free from the sludge with ease. "But I wasn't living up to my own ideals! Pros are always risking their lives!"

 

All Might pulled his fist back. The air around him seemed to warp.

 

"DETROIT SMASH!"

 

The punch was infinitely more powerful than the one under the bridge. The resulting shockwave tore through the alley, extinguishing the raging fires instantly. The wind pressure blew the Sludge Villain into microscopic droplets, scattering him across the pavement. A massive updraft shot into the sky, tearing the clouds apart.

 

Seconds later, it began to rain.

 

The crowd was dead silent. Then, they erupted into deafening cheers. All Might had changed the weather with a single punch.

 

In the aftermath, the heroes took charge. While Bakugo was surrounded by pros praising his powerful Quirk and his resilience, Izuku was pulled aside by Death Arms and Kamui Woods.

 

"What were you thinking?!" Death Arms scolded, pointing a stern finger at Izuku. "You have no Quirk, no training, and you rushed an active villain! You could have gotten yourself and the hostage killed! Leave this to the professionals next time!"

 

Izuku bowed his head, looking at his scuffed red sneakers. "I'm sorry. I know. I just... I couldn't watch."

 

He walked home as the sun began to set, casting long, orange shadows over the city streets. He was exhausted. His muscles ached with a deep, burning soreness he had never felt before—a remnant of Kurama's forced chakra injection.

 

I really am an idiot, Izuku thought. I tried to play hero, and I just got in the way.

 

"Hey! Deku!"

 

Izuku stopped, turning around. Bakugo was jogging toward him, breathing heavily. The ash blonde boy stopped a few feet away, his fists clenched at his sides. He looked angry, embarrassed, and conflicted all at once.

 

"Listen to me, you Quirkless nobody!" Bakugo shouted, pointing an accusatory finger. "I didn't need your help! I had him right where I wanted him! Don't think you can look down on me! You didn't save me! Got it?!"

 

Bakugo spun on his heel and stomped away, his pride bruised but his message delivered.

 

Izuku managed a weak, exhausted smile. Same old Kacchan.

 

He turned to continue his walk home, but stopped dead in his tracks.

 

Standing at the intersection, leaning against a telephone pole in his deflated, skeletal form, was All Might.

 

"I am here!" All Might announced, though he quickly coughed into his hand, ruining the dramatic effect.

 

"All Might?! What are you doing here?" Izuku gasped, rushing over. "Did you shake off the reporters?"

 

"Hah! Shaking off reporters is child's play for me!" All Might boasted, before his face softened. He looked down at the green-haired boy. "I came to find you, young man. I have a correction to make. And a proposal."

 

Izuku blinked. "A... proposal?"

 

"On that rooftop, I told you that you couldn't be a hero. I was wrong," All Might said, his voice solemn and filled with a profound respect. "Today, when none of us pros acted, when we were paralyzed by fear or circumstance, it was you—a timid, Quirkless boy—who ran into the fire."

 

Izuku's breath hitched. His eyes began to well with tears.

 

"Most top heroes have a story about their school days," All Might continued, taking a step forward. "A story where their bodies moved before they had a chance to think. That is what happened to you today, isn't it?"

 

Izuku fell to his knees. He clutched the fabric of his pants, unable to hold back the floodgates. The tears he had suppressed in the doctor's office ten years ago, the tears he had held back on the rooftop, all of them poured out. He sobbed openly in the middle of the street.

 

"You can become a hero," All Might declared, his voice echoing with the weight of destiny.

 

It was the only thing Izuku had ever wanted to hear. The validation he had craved his entire life, delivered by the man he admired most.

 

All Might let the boy cry for a few moments before speaking again. "You are worthy to inherit my power."

 

Izuku snapped his head up, his tear-streaked face locked in an expression of utter confusion. "Inherit? Your power? What do you mean?"

 

"I am offering you my Quirk, young man," All Might said, a grin stretching across his skeletal face. "It's a power that has been passed down from generation to generation, cultivating strength, crying out for justice. It is called One For All. And I believe you are the perfect vessel for it."

 

Izuku stared at him, his mind reeling. A Quirk that could be transferred? It sounded like something out of a comic book. But this was All Might. He wouldn't lie.

 

"I... I accept," Izuku whispered, his voice trembling with newfound resolve. "I want to be a hero. I'll do whatever it takes."

 

All Might beamed. "Excellent! Your training begins tomorrow. We have ten months before the U.A. entrance exams. I will mold you into a vessel capable of holding my power!"

 

As All Might detailed the rigorous physical training ahead, Izuku felt a spark of hope ignite in his chest. He was finally going to get a Quirk. He was finally going to be a hero.

 

But deep within the recesses of his soul, down in the damp, dark sewer of his mindscape, the giant fox opened his crimson eyes.

 

Kurama listened to the blonde hero's speech, feeling the sheer, overwhelming, ghostly power that the man possessed. And he felt Izuku eagerly accept the offer to put that foreign, spectral energy inside his body. Inside Kurama's territory.

 

The fox bared his skyscraper-sized fangs in a terrifying, wrathful sneer.

 

"You think you can bring another power into this vessel?" Kurama rumbled, his voice shaking the very foundations of Izuku's mind. The water in the sewer began to churn into a violent whirlpool. "You think you can share space with the Nine-Tails? Try it, boy. Let's see how this 'One For All' holds up against my fire."

 

The die was cast. Izuku Midoriya was no longer just a Quirkless fanboy. He was about to become the battleground for two of the most powerful forces the world had ever seen.

 

 

The smell of Dagobah Municipal Beach Park was something that offended the senses on a molecular level. It was a pungent, rotting bouquet of rusted iron, decaying seaweed, stagnant seawater, and the lingering stench of forgotten household garbage. For years, the ocean currents had turned this particular stretch of coastline into an illegal dumping ground. Mountains of discarded refrigerators, crushed cars, and shattered CRT televisions blotted out the horizon.

 

It was here, amidst the towering monoliths of trash, that Izuku Midoriya’s path to becoming a hero truly began. And it was here that he quickly realized how monumentally ill-equipped his body was for the task.

 

"Hey, hey, hey! Is that all you've got, young Midoriya?!" All Might's booming voice echoed across the beach, cutting through the crash of the morning waves. The Number One Hero, currently in his skeletal, deflated form, sat comfortably atop a broken washing machine. He blew a sharp whistle. "The refrigerator isn't going to move itself! Put your back into it!"

 

Izuku strained against the heavy rope tied around his chest, the coarse hemp biting into his skin through his white t-shirt. His sneakers dug into the wet sand, slipping backward with every inch he tried to gain. Behind him, a massive, rusted, double-door refrigerator refused to budge. His arms felt like they were filled with molten lead, his lungs burning with every desperate gasp of salty air.

 

"I'm... trying... All Might!" Izuku wheezed, his vision swimming with black spots. He gave one final, agonizing pull, managing to drag the appliance perhaps a single centimeter before his legs gave out entirely. He collapsed face-first into the sand, groaning as the grit coated his sweat-drenched face.

 

All Might jumped down, his expression softening. He handed Izuku a water bottle. "You're doing well for your second week, my boy. But 'Aim to Pass: American Dream Plan' is designed to push you beyond your limits. One For All is a tremendous physical burden. If I were to pass it to you in your current state, your limbs would blow clean off!"

 

Izuku shivered, spitting out a mouthful of sand. "B-Blow clean off?"

 

"Indeed! The stockpile of power is too vast for an unconditioned vessel. We have ten months to turn you from a flimsy lawn chair into a heavy-duty steel bench!" All Might gave a thumbs-up. "Rest up. Tomorrow, we tackle the tires!"

 

That night, Izuku didn't even make it to his bed. He collapsed onto the floor of his bedroom, his muscles screaming in pure agony. Every joint ached, every fiber of his being felt as though it had been put through a meat grinder. As his eyes fluttered shut, the comforting darkness of sleep took him.

 

But rest did not come.

 

Drip.

 

Splash.

 

Izuku groaned, peeling his eyes open. He was lying in the shallow, lukewarm water of the sprawling, cavernous sewer system. The ambient red light pulsed faintly against the slick stone walls.

 

"Not this place again," Izuku muttered, slowly pushing himself to a sitting position. He flinched, clutching his shoulder. Even in his mindscape, the phantom pains of the beach training lingered.

 

"My thoughts exactly, meat-sack."

 

The voice hit him like a physical shockwave, vibrating through the water and rattling Izuku’s ribs. From the shadows of the colossal cage before him, the towering, terrifying silhouette of the Nine-Tailed Fox emerged. Kurama lowered his massive head, pressing his wet, leathery nose against the golden iron bars. The sheer size of the beast was incomprehensible; a single one of his teeth was larger than Izuku's entire body.

 

"Y-You!" Izuku scrambled backward, his heart hammering in his chest. "The giant fox! You're real! You were the one who saved me from the Sludge Villain!"

 

Kurama snorted, a plume of hot, sulfurous smoke billowing from his nostrils and washing over the boy. "Do not mistake self-preservation for altruism, brat. If that walking pile of filth had suffocated you, I would have perished with you. A humiliating end I refuse to accept."

 

Izuku stared, his initial fear quickly being overshadowed by his innate, obsessive curiosity. He scrambled to his feet, ignoring the ache in his legs, and splashed right up to the bars. "So you are my Quirk! A sentient mutation-emitter hybrid? Wait, no, the doctors said I don't have a Quirk factor. Are you an ancient parasite? A symbiotic organism?"

 

Kurama’s crimson eyes narrowed, his nine massive tails thrashing agitatedly in the darkness behind him. "Silence your incessant muttering! I am Kurama. The Nine-Tailed Fox. A being of pure chakra. And currently, I am suffering the indignity of feeling every pathetic, tearing muscle fiber in your appallingly weak body."

 

Izuku blinked. "You... you can feel my soreness?"

 

"We share a nervous system, you imbecile," Kurama growled, slamming a paw against the floor. "Your physical exhaustion bleeds into this seal. I cannot sleep because your body is screaming in agony over moving a rusted box of metal. It is pathetic. I am the pinnacle of demonic power, and my vessel is defeated by a kitchen appliance!"

 

"I'm sorry!" Izuku bowed deeply, though he felt a sudden spark of indignity. "But I have to get stronger! All Might is going to give me his power, and I need a strong vessel to hold it!"

 

At the mention of All Might's power, Kurama’s upper lip curled into a terrifying sneer. "That skeletal fool's borrowed energy? You think you need his power when you harbor me? The sheer disrespect..." Kurama scoffed, turning his massive head away. "Listen to me, boy. I cannot stand this agonizing weakness any longer. If you are going to train, you are going to do it correctly. I will not endure ten months of your physical incompetence."

 

Izuku looked up, eyes wide. "Are... are you offering to train me?"

 

"I am offering to make my own existence tolerable," Kurama corrected sharply. "Sit down. Cross your legs. Close your eyes."

 

Izuku hesitated, then quickly dropped into a cross-legged position in the shallow water.

 

"Your world relies on 'Quirks'—genetic lotteries that require no discipline," Kurama lectured, his deep voice taking on a begrudgingly authoritative tone. "Chakra is different. It is the fundamental energy of life, forged from the perfect harmony of physical stamina and spiritual energy. By pulling on cars, you are building the physical. But you are ignoring the spiritual. You are wasting energy."

 

"How do I use it?" Izuku asked eagerly.

 

"Focus on your stomach. Below your navel. That is the seat of your coils. Feel the heat there."

 

Izuku closed his eyes and concentrated. At first, there was nothing but the dull ache of his muscles. But slowly, guided by the oppressive, heavy presence of the ancient demon before him, he felt it. A tiny, flickering ember of warmth.

 

"Now, picture that warmth flowing through your veins like blood. Push it to your limbs. Let it reinforce your tearing muscles."

 

Izuku took a deep breath. He visualized the warmth spreading, carrying it through his chest, down his arms, and into his aching legs. In the real world, the microscopic red mist Izuku had always assumed was a weak healing Quirk flared to life beneath his skin. The agony in his joints instantly dulled, replaced by a thrumming, buzzing vitality.

 

"Do not let it out of your body," Kurama warned. "Keep it internal. Coat your muscles in it. It will give you the strength to move your garbage without disturbing my slumber. Now, get out of my sight."

 

A massive tail swept forward, the sheer wind pressure throwing Izuku backward.

 

Izuku woke up on his bedroom floor with a gasp. Sunlight was streaming through his window. He cautiously pushed himself off the floor. The agonizing pain from yesterday was gone, replaced by a tight, energetic springiness in his steps. He looked at his hands, clenching them into fists.

 

A slow, determined smile spread across his face.

 

The next few months on Dagobah Beach were a revelation. All Might watched in absolute bewilderment as his scrawny successor began to tear through the American Dream Plan. Izuku wasn't using explosive strength—he wasn't lifting cars over his head—but his stamina had skyrocketed. By unconsciously circulating the minuscule amounts of his own chakra (and the microscopic leaks from Kurama's seal), Izuku reinforced his muscles, preventing fatigue and minor injuries.

 

He pushed trucks, hauled heavy safes, and cleared massive swaths of the beach. The reluctant mentor dynamic between the boy and the beast deepened. Whenever Izuku slept, Kurama would bark criticisms at him. “Your stance is too wide! You are wasting kinetic energy!” or “Stop relying purely on your arms, you fool! Drive the chakra into your calves!”

 

Izuku never mentioned the giant fox to All Might. He feared the hero would think he was insane, or worse, that he already had a Quirk and was lying to him. Kurama was his secret. A grumpy, terrifying, ancient secret.

 

Finally, the ten months were up.

 

It was the morning of the U.A. Entrance Exam. The sun rose over a pristine, glittering Dagobah Beach. The mountains of trash were gone, revealing the pristine white sand and the crashing blue waves of the ocean.

 

Standing at the edge of the seawall, looking out at the horizon, was Izuku Midoriya. He had stripped off his shirt, revealing a physique that was entirely unrecognizable from the scrawny boy ten months prior. His muscles were lean, corded, and defined, built through excruciating labor and optimized by ancient energy control.

 

"Oh my... OH MY... GOODNESS!"

 

All Might stood behind him, in his fully muscled, heroic form, clutching a smartphone. "You actually did it! You cleared the entire beach! And you even had time to spare! Young Midoriya, you have exceeded my expectations!"

 

Izuku turned around, panting, a brilliant smile on his face. "I... I wanted to make sure I was ready, All Might!"

 

All Might stepped forward, placing a heavy, warm hand on Izuku's shoulder. "You have proven your physical grit. Your vessel is ready. It is time to bestow upon you the power of One For All."

 

Izuku’s heart leapt into his throat. This was it. The moment his life truly changed.

 

All Might reached up and plucked a single, golden strand of hair from his head. He held it out between his thumb and forefinger, the morning sun catching the blonde strand.

 

"Eat this," All Might said, his expression entirely serious.

 

Izuku froze. The dramatic tension shattered into a million pieces. "Huh?"

 

"To inherit the power, you must consume some of my DNA! A hair is the easiest way. Come now, chew it up and swallow! We don't have much time before the exam!"

 

Gagging slightly, Izuku took the hair, squeezed his eyes shut, and forced it down his throat. It felt awful, scratching all the way down.

 

"Excellent!" All Might beamed. "It will take a few hours to digest and integrate into your nervous system. By the time the practical exam starts, you should feel it!"

 

Izuku nodded, trying not to throw up. "R-Right. Thank you, All Might!"

 

But as Izuku turned to pack up his bag, a sudden, blinding spike of pain shot through his skull. He stumbled, gripping his forehead.

 

"Young Midoriya? Are you alright?" All Might asked, stepping forward.

 

"Just... dizzy," Izuku lied, his vision swimming.

 

The moment the strand of hair settled in his stomach, Izuku’s consciousness was violently yanked inward.

 

SPLASH.

 

Izuku hit the waters of the mindscape hard. But the sewer wasn't calm today. The water was boiling, hissing as thick clouds of steam rose into the air. The ambient red light was flashing violently, like a warning siren.

 

Above the cage, a tear in the sky of the mindscape ripped open. A brilliant, multi-colored ball of lightning—a wisp of pure, crystallized energy—descended into the cavern. It pulsed with a terrifying, overwhelming presence. Inside the orb, Izuku could faintly see the silhouettes of eight distinct figures. Ghosts. Vestiges of the past.

 

"NO!"

 

The roar was so loud it physically hurt Izuku’s ears. Kurama slammed his massive body against the golden bars of his cage, shaking the entire foundation of Izuku’s soul. The fox’s eyes were wide with pure, unadulterated fury.

 

"Parasites! Intruders! In MY domain!" Kurama howled, his nine tails thrashing violently.

 

The orb of One For All floated innocently toward the center of the room, radiating a warm, heroic light that directly opposed Kurama's dark, heavy malice.

 

Kurama reached a massive claw through the bars, swatting at the orb of light. "I am the Nine-Tails! I do not share my vessel with the rotting ghosts of a bygone era! Begone!"

 

Kurama channeled a massive surge of dense, red chakra, wrapping it around the spark of One For All. He couldn't destroy it—the power was permanently etched into Izuku's DNA now—but he absolutely refused to let it flow freely. With a vicious snarl, Kurama dragged the orb of One For All into the furthest, darkest corner of the mindscape, wrapping it in thick chains of red chakra.

 

"Kurama! Stop! What are you doing?!" Izuku yelled, wading forward. "That's All Might's Quirk!"

 

"It is a foreign contagion!" Kurama snapped, glaring down at Izuku, his fangs bared. "It is filled with the residual consciousness of eight dead mortals! I will not allow them to pollute this space! This vessel belongs to YOU and ME, brat!"

 

"But I need that power for the exam!" Izuku pleaded.

 

"You need to master your own body before you rely on borrowed parlor tricks!" Kurama roared. "I have spent ten months teaching you to harness your own energy. If you tap into that chaotic stockpile of power now, with no understanding of its flow, it will shatter your bones to dust! I have quarantined it. You are forbidden from touching it until I deem you worthy, meat-sack!"

 

"You can't do that!" Izuku cried.

 

"I just did," Kurama sneered, turning his back and retreating into the darkness of his cage. "Survive on your own merits today, brat. Or die trying."

 

Izuku was forcefully ejected from the mindscape, gasping for air on the beach. All Might was looking at him with concern.

 

"I'm fine!" Izuku choked out, grabbing his backpack. "Just... nervous! I have to go to U.A. now!"

 

As he ran toward the train station, Izuku felt a deep, sinking pit in his stomach. He finally had a Quirk. The greatest Quirk in the world. And his internal, demonic roommate had locked it in a closet.

 

 

 

The towering gates of U.A. High School were intimidating enough to make Izuku’s knees knock together. He stood among hundreds of hopeful applicants, all boasting incredible Quirks and confidence. He took a step forward, tripped over his own scuffed sneaker, and braced for a face-plant.

 

Before he hit the concrete, he felt himself become weightless.

 

"Are you okay?" a cheerful voice asked. Izuku turned his head to see a girl with a brown bob and permanent blush on her cheeks. She pressed her fingertips together, releasing him from the anti-gravity effect. "It's my Quirk! Sorry for using it without asking, but it'd be bad luck to fall before the exam!"

 

Izuku, who had never spoken to a girl outside of his mother, turned the color of a ripe tomato. "I-Uh-Ah-Thank you!"

 

She beamed and walked into the auditorium. Izuku stared after her, his heart fluttering. I talked to a girl!

 

The written exam went smoothly—Izuku's obsessive note-taking habits paying off in spades. But the practical exam was what terrified him. He stood in front of the massive gates of Mock City Center B, clad in his green tracksuit. Around him, applicants were stretching, showing off their Quirks. Bakugo was in a different testing center, a small mercy.

 

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

 

The crowd surged forward. Izuku stood frozen for a second before sprinting after them.

 

Okay, Izuku thought, his breathing ragged. Kurama locked away One For All. But I still have the physical conditioning. I just have to circulate my chakra like he taught me.

 

Izuku focused on his stomach, pulling the warm energy through his limbs. He rounded a corner and came face-to-face with a massive, one-wheeled green robot—a One-Pointer.

 

The robot locked onto him. "TARGET ACQUIRED."

 

Izuku panicked. He ducked under a metal fist, his chakra-enhanced speed saving him from a concussion. He pulled back his fist, channeling as much internal energy as he could, and punched the robot's chassis.

 

CLANG.

 

His knuckles bruised. The robot merely dented. Izuku winced, jumping backward. He didn't have super strength. He just had enhanced human physicals. It wasn't enough to break solid steel with his bare hands.

 

Before the robot could counterattack, a laser blasted through its head. A blonde boy with a sparkling belt winked at Izuku as he ran past. "Merci, monsignor!"

 

"Six minutes left!" Present Mic announced.

 

Izuku’s heart hammered in his chest. Zero points. He had zero points. He ran through the streets, desperately looking for weaker robots, but the other applicants were tearing through them with explosive Quirks, acid, and super-speed. Every time Izuku found a target, it was stolen.

 

I'm going to fail, Izuku thought, despair clawing at his throat. After everything. After All Might believed in me. After moving all that trash. I'm just a Quirkless loser.

 

Suddenly, the ground beneath his feet shuddered violently.

 

A shadow fell over the mock city, blotting out the sun. Buildings began to crumble and shatter as a machine of apocalyptic proportions rolled down the main avenue. It was the Zero Pointer—an obstacle so massive it looked like a skyscraper on tank treads.

 

"Run away!" applicants screamed, turning tail and fleeing in terror.

 

Izuku froze, his legs trembling. The sheer scale of the machine was terrifying. Every instinct screamed at him to run. He turned, ready to flee with the others.

 

"Ow! Please... somebody!"

 

Izuku stopped dead. He looked back.

 

Trapped under a slab of concrete, dangerously close to the crushing treads of the approaching behemoth, was the nice girl with the gravity Quirk. She was clutching her ankle, tears streaming down her face, desperately trying to free herself.

 

The other applicants ran past her, focused only on their own survival.

 

Izuku didn't think. The same impulse that had driven him to save Bakugo hijacked his nervous system. He dug his sneakers into the pavement and sprinted straight toward the mountain of steel.

 

Deep within the mindscape, Kurama watched through Izuku's eyes.

 

"Fool!" Kurama barked. "What do you think you can do against that? Your body cannot handle that mass! Turn back, meat-sack!"

 

No, Izuku’s voice echoed in the mindscape, startling the fox. The boy’s mental projection appeared in the sewer, standing right in front of Kurama’s cage. Izuku’s eyes were blazing with a fierce, emerald determination. I will not run away while someone needs help!

 

Izuku ran toward the corner of the mindscape, where the glowing orb of One For All was wrapped in thick, red chakra chains.

 

"I forbid you!" Kurama roared, slamming a paw near Izuku. "Your bones will shatter! I will not spend the next month healing your mangled limbs!"

 

I don't care! Izuku yelled, grabbing the red chains with his bare (mental) hands. All Might trusted me with this! I have to use it!

 

Through sheer force of will, fueled by absolute selflessness, Izuku tore the chains away. He plunged his hands into the glowing, multi-colored orb of One For All.

 

In the real world, the change was instantaneous.

 

Izuku leaped into the air. But this wasn't a normal jump. Brilliant, glowing red veins traced up his legs as the sheer, unadulterated power of One For All flooded his unprepared nervous system. The concrete beneath him detonated into a massive crater, launching him hundreds of feet into the air like a ballistic missile.

 

He soared up until he was eye-level with the colossal head of the Zero Pointer.

 

The wind whipped his hair wildly. He felt the terrifying, electric static of One For All pooling in his right arm. The pressure was agonizing; it felt like his arm was packed with a thousand pounds of explosives.

 

"SMASH!"

 

Izuku threw the punch.

 

The impact was deafening. A shockwave of pure kinetic energy erupted from his knuckles, warping the air itself. The solid steel face of the Zero Pointer caved inward with a sickening crunch. The force of the blow traveled through the machine's entire structure, ripping it apart from the inside out. With a cacophonous groan of tearing metal, the behemoth toppled backward, exploding into a rain of debris.

 

Below, Uraraka and the fleeing applicants watched in stunned silence as the boy who had zero points obliterated the unstoppable obstacle with a single blow.

 

But gravity is a cruel mistress.

 

As Izuku began to fall from the sky, the adrenaline faded, replaced by absolute, blinding agony. He looked at his right arm. It was a mangled, purple, swollen mess, flopping uselessly in the wind. He tried to move his legs to prepare for a landing. Nothing. Both of his legs were shattered from the sheer force of the jump.

 

My arm and legs are broken, Izuku realized, panic finally setting in as the ground rushed up to meet him. I can't use One For All to cushion my fall. I'm going to hit the pavement. I'm going to die.

 

Tears leaked from his eyes. He squeezed them shut. I'm sorry, Mom. I'm sorry, All Might. I guess I really wasn't ready.

 

In the mindscape, Kurama was absolutely furious.

 

"I TOLD YOU, YOU STUPID BRAT!" Kurama roared, his voice shaking the very heavens of Izuku's soul. The fox slammed his massive paws against the cage bars, his chakra flaring with an intensity that boiled the sewer waters. "You shattered your vessel for a girl you met five minutes ago! But I am the Nine-Tailed Fox! I survived ancient wars! I survived the Uchiha! I AM NOT DYING AS A SPLAT ON A PAVEMENT BECAUSE MY JAILER IS A SUICIDAL IDIOT!"

 

Kurama didn't hold back this time. He couldn't afford to. The boy was seconds away from a fatal impact. The fox gathered a massive, dense pool of his corrosive, demonic chakra and violently shoved it through the seal.

 

To the applicants watching below, it looked as though Izuku was going to fall to his death.

 

But fifty feet above the ground, a terrifying sound ripped through the air. It wasn't an explosion. It sounded like the furious, guttural roar of a wild beast.

 

Suddenly, a thick, boiling cloak of crimson, translucent energy erupted from Izuku's pores. It didn't just coat his skin; it expanded outward, taking on the vague silhouette of a massive fox's head. The air around him superheated, distorting the light. Behind him, a single, massive tail made of pure, bubbling red chakra manifested, thrashing wildly.

 

"What... what is that?!" Uraraka gasped, shielding her face from the sudden wave of intense heat.

 

The red chakra cloak acted as a parachute and a thruster. The single tail slammed into the side of a mock building, slowing his descent drastically, melting the concrete upon impact. Izuku hit the ground, the red chakra cushioning the fall. The pavement beneath him hissed and melted into a glass-like slag from the sheer heat of Kurama's energy.

 

Izuku lay in the center of the molten crater, the red cloak bubbling around him. His eyes snapped open—not green, but glowing, slit-pupiled crimson. He let out a ragged, feral gasp as the red chakra immediately went to work. The demonic energy forcefully and brutally forced his shattered bones back into place. The sound of cracking, realigning bone echoed in the quiet street.

 

The pain of the rapid, forced healing was worse than the break. Izuku screamed, his vision going white, before his consciousness finally gave out entirely.

 

The red chakra immediately receded, sinking back into his skin as if it had never been there, leaving behind a boy with perfectly healed, albeit deeply exhausted, limbs.

 

"Time's up!" Present Mic's voice rang out, ending the exam.

 

Silence fell over the testing center. The other applicants slowly crept toward the crater, staring at the unconscious boy. They had just witnessed a kid use a Quirk that shattered his own body to fell a titan, only to manifest a second, terrifying, monstrous power to heal himself.

 

 

 

Several hours later, in a darkened, heavily secured room deep within U.A. High School, three figures sat around a glowing monitor.

 

Nezu, the principal of U.A., steepled his paws together, his beady black eyes reflecting the paused footage on the screen. Beside him stood Shota Aizawa, the underground hero Eraserhead, looking more tired than usual. To his right sat Chiyo Shuzenji, Recovery Girl.

 

"Fascinating," Nezu murmured, rewinding the footage for the fifth time.

 

On the screen, Izuku leaped, destroying the Zero Pointer. The camera zoomed in on his right arm, clearly showing the bone shattering under the internal pressure.

 

"The boy's registry file says he is Quirkless," Aizawa noted, his voice flat and analytical. "Clearly, the registry is wrong. But this is... highly irregular. The sheer output of that strength enhancement is staggering. It resembles All Might’s Quirk, but with absolutely zero biological limiters. It destroyed his body instantly."

 

"It's the foolishness of youth," Recovery Girl sighed, shaking her head. "A body must be conditioned for a Quirk. To manifest something that volatile... it's a miracle he didn't blow his arm entirely off."

 

"But that is not the most intriguing part, is it, Shota?" Nezu said, tapping a button.

 

The video skipped forward to the fall. They watched in frame-by-frame slow motion as the boiling, red energy erupted from Izuku. They saw the distinct shape of the fox's head, the single thrashing tail. They watched the concrete melt upon contact with the energy, and they watched the brutal, instantaneous realignment of his broken bones.

 

"Two completely distinct phenomena," Aizawa muttered, his eyes narrowing. He rubbed his chin beneath his scarf. "A self-destructive stockpile of kinetic energy, and a localized, sentient, highly corrosive mutation-emitter cloak that possesses rapid cellular regeneration capabilities. They don't match. They don't even look like they belong to the same species."

 

"When he was brought into the infirmary," Recovery Girl added, looking troubled, "I ran a scan. His bones were perfectly healed. But his cellular stamina was completely drained. Furthermore, there was a strange, dense residue in his bloodstream that my machines couldn't identify. It felt... ancient. Hostile."

 

Nezu leaned back in his chair, a small smile playing on his snout. "Izuku Midoriya. A boy with a body that breaks under its own power, and a beast inside him that refuses to let him die. I believe, gentlemen, that this year's roster is going to be incredibly entertaining."

 

Aizawa just scowled at the screen, looking directly at the glowing crimson eyes caught on the freeze-frame. "He's a liability. If he can't control whatever that monster is inside him, he's going to kill someone. Or himself."

 

"Then it is our job to teach him, Shota," Nezu replied cheerily. "After all, U.A. is the pinnacle of hero education. Let us see if we can tame the beast."

 

Far away from the school, in his bedroom, Izuku slept deeply. For the first time in months, the sewer in his mind was quiet. Kurama lay with his head on his paws, watching the small, glowing orb of One For All that Izuku had freed. The fox did not chain it again.

 

"You have spirit, boy," Kurama rumbled to the sleeping mindscape. "I will give you that. But you have much to learn before you can wield my fire."

 

 

The towering, H-shaped building of U.A. High School was a monument to modern heroics, a glass-and-steel fortress where dreams were forged into reality. For Izuku Midoriya, walking through its gates felt less like a dream and more like stepping onto a battlefield.

 

He found Class 1-A with relative ease, despite the door being comically oversized. Taking a deep breath, he slid the door open, hoping for a calm, professional environment.

 

"Take your feet off that desk immediately! It is disrespectful to our upperclassmen and the craftsmen who made it!"

 

"Hah?! What middle school did you go to, you extra?! I'll put my feet wherever I want!"

 

Izuku sighed. The stern, bespectacled Tenya Iida and the explosive Katsuki Bakugo were already at each other’s throats. It was like middle school all over again, just with a much nicer budget.

 

"Oh! It's you! The falling boy!"

 

Izuku turned to see the nice girl from the entrance exam—Ochaco Uraraka—beaming at him. Before he could string together a coherent sentence to greet her, a chilling, lethargic voice cut through the noise of the classroom.

 

"If you're just here to make friends, you can pack up your things and leave."

 

The entire class froze. A man wrapped in a bright yellow sleeping bag rolled into the doorway like a giant, heavily caffeinated caterpillar. He unzipped the bag and stood, revealing a scraggly, unshaven face, bloodshot eyes, and a tangled mess of black hair.

 

"I'm Shota Aizawa. Your homeroom teacher. Put these on and meet me on the P.E. grounds," he droned, pulling a blue and white gym uniform from his sleeping bag. "We're doing a Quirk Apprehension Test."

 

 

 

The sun beat down on the dirt field as Class 1-A stood in an anxious cluster. Aizawa, looking as though he would rather be anywhere else, held up a digital tracking device.

 

"Bakugo. You scored the most points on the practical exam," Aizawa said, tossing a baseball to the explosive blonde. "What was your farthest throw in middle school?"

 

"Sixty-seven meters," Bakugo grunted, catching the ball.

 

"Try doing it with your Quirk. Anything goes, just stay in the circle."

 

Bakugo stepped into the chalk ring, a feral grin stretching across his face. He wound his arm back, his muscles tensing. "DIE!" he roared, blasting a massive explosion from his palm as he released the ball. The shockwave rattled Izuku’s teeth.

 

The ball rocketed into the sky, leaving a trail of smoke. Aizawa held up the tracker. 705.2 meters.

 

The class erupted into excited murmurs, marveling at the sheer freedom and power allowed at U.A.

 

"Awesome! This looks like fun!" a girl with pink skin cheered.

 

Aizawa's eyes narrowed. His dark hair seemed to writhe for a fraction of a second. "Fun? You have three years to become heroes. You think it's all going to be fun and games? Fine. Whoever scores the lowest across all eight events will be judged hopelessly lacking... and will be expelled."

 

A collective gasp echoed across the field. Expelled on the first day?

 

Izuku’s stomach dropped. Eight events. Sprints, grip strength, standing long jump... these are pure physical tests.

 

Deep within the dark, watery expanse of Izuku’s mindscape, a massive, slit-pupiled eye snapped open.

 

"Expulsion?" Kurama’s voice echoed in Izuku’s subconscious, dripping with derision. "This sleep-deprived vagrant thinks he can dismiss my vessel? Use my chakra, boy. Reinforce your muscles. Don't let me down."

 

I will, Izuku thought back, focusing on his breathing. But I need to be careful. If I leak too much, everyone will see the red energy. I need to keep it internal, like we practiced.

 

Throughout the first few tests, Izuku did exactly that. During the 50-meter dash, he circulated a microscopic amount of Kurama’s chakra into his calves, netting a respectable 5.5 seconds. For the grip strength test, he pulsed the chakra into his forearms, squeezing the machine to an impressive 150 kilograms. It wasn't enough to beat the multi-armed Shoji or the engine-legged Iida, but it kept him comfortably in the middle of the pack.

 

But as the events progressed, the physical toll began to mount. The internal circulation was exhausting his natural stamina. By the time they reached the softball throw, Izuku was panting heavily, his muscles trembling.

 

"Midoriya. You're up," Aizawa called out, his tone utterly bored.

 

Izuku stepped into the circle, the baseball feeling heavy in his sweaty palm. He looked at the horizon. Internal chakra isn't going to cut it here. I need explosive power. I have to use One For All. But I can't break my arm again. Recovery Girl said my body still isn't ready for a full 100% output.

 

Izuku squeezed his eyes shut. He visualized the glowing, multi-colored orb of One For All locked away in the corner of his mind. He didn't need the whole thing. He just needed a fraction. He imagined drawing a single, sparking green thread from the orb and wrapping it around his right arm.

 

He opened his eyes. Faint, red glowing lines traced across his skin.

 

Aizawa watched from the sidelines, his bloodshot eyes unblinking behind his capture scarf. The kid with the self-destructive Quirk and the healing monster. Let's see which one he tries to use.

 

Izuku wound his arm back. The power of One For All rushed into his bicep, surging toward his fingertips. He threw his arm forward with everything he had.

 

FWIP.

 

The ball left his hand with a pathetic, hollow thud, landing a mere 46 meters away.

 

Izuku blinked, staring at his hand. The sparking power was completely gone. "Huh? But I felt it..."

 

"I erased your Quirk," Aizawa's voice rang out, cold and sharp.

 

Izuku turned. Aizawa’s goggles were raised, his dark hair floating defying gravity. His eyes glowed a furious red. But Aizawa wasn't just using his Quirk—he was grimacing, a thin bead of sweat rolling down his temple.

 

What the hell is this? Aizawa thought, fighting the urge to rub his burning eyes.

 

When Eraserhead looked at a person with an Emitter or Transformation Quirk, he essentially paused their Quirk factor. It was a sterile, clinical process. But looking at Midoriya was like staring directly into a solar eclipse. He had easily severed the boy's connection to the stockpiling Quirk (One For All). But behind it...

 

Behind it, Aizawa felt a presence. A dark, suffocating, ancient malice that made the hair on his arms stand up. His erasure could not touch it. It was like trying to put out a forest fire by glaring at it. The sheer density of the foreign energy was physically stinging Aizawa's eyes.

 

"You..." Aizawa gritted his teeth, forcing through the discomfort. "From what I saw on the entrance exam tape, you have two powers. A destructive one and a monstrous one. And you can't control either. If you rely on that self-destructive power again, you will be incapacitated, and someone will have to save you. You are a liability. You cannot become a hero with that power."

 

Aizawa blinked, his hair falling flat. He let out a harsh breath, the burning sensation in his eyes finally fading. "I've returned your Quirks. Take your final throw. Get it over with."

 

Izuku stood frozen in the circle. The words cut deep, echoing All Might's original rejection on the rooftop. He's right. If I use 100% of One For All, I'll break my arm. If I rely fully on Kurama, I might lose control of the red chakra like at the exam. I have to combine them. I have to find the balance.

 

Down in the mindscape, the water boiled.

 

"That insufferable mortal dared to try and erase ME?!" Kurama roared, his tails whipping the sewer water into a frenzy. "Show him, brat! Let my chakra loose! Burn his pathetic scarf to ashes!"

 

No, Izuku replied, his mental voice calm but firm. If I let it all out, I'll hurt someone. But I need your help, Kurama. Just a little. A cloak. Just enough to absorb the recoil.

 

Kurama paused, his massive eyes narrowing. The boy was asking, not demanding. "Hmph. Do not make a habit of this. I will give you a sliver. But you must force that ghostly, foreign power to do the heavy lifting."

 

Izuku took a deep breath. He looked down at his hand. He channeled One For All, but instead of his whole arm, he focused the sparking, green lightning entirely into his right index finger.

 

At the exact same time, he pulled on the seal.

 

The air around Izuku suddenly warped. A heavy, oppressive heat washed over the field. Class 1-A collectively took a step back, shivering despite the warm day.

 

FSHH.

 

A thin, bubbling layer of translucent red energy erupted from Izuku's skin. It didn't form a massive fox head this time; it was tightly compressed, clinging to him like a second skin. One single, thin tail of red chakra swayed lazily behind him.

 

"What the..." Bakugo whispered, his red eyes widening. That's the monster from the exam.

 

Aizawa readied his capture scarf, every instinct screaming at him that a lethal threat had just entered the field.

 

Izuku didn't hesitate. He wound his arm back. As his arm whipped forward, he unleashed the 100% One For All smash localized entirely in his index finger.

 

The dual forces clashed and synergized. The concussive, explosive wind pressure of One For All detonated from his fingertip, rocketing the ball into the stratosphere with a sonic boom that shattered the glass of the gymnasium windows.

 

Simultaneously, the recoil—the bone-shattering backlash that would have normally turned his finger into a mangled pulp—was violently absorbed by the One-Tail chakra cloak. The red energy hissed, violently repairing the micro-tears in his muscle and bone the millisecond they occurred.

 

The wind cleared. The red cloak sank back into Izuku's skin, vanishing without a trace. Izuku stood there, his index finger bruised a deep purple, throbbing with pain, but unbroken.

 

He turned back to Aizawa, clutching his hand to his chest. "Mr. Aizawa... I'm still standing."

 

Aizawa stared at the tracker in his hand. 705.3 meters.

 

A feral, terrifying smile tugged at the corner of the underground hero's mouth. "This kid..."

 

The class went wild. "He threw it over 700 meters! And did you see that red aura?! What was that?!"

 

But one person wasn't cheering.

 

Katsuki Bakugo stood paralyzed, his mind racing. He has a Quirk. Two Quirks? No, that's impossible. He's been Quirkless his whole life. We went to the same doctors! We grew up together! Did he lie to me? Did he hide this monstrous power for ten years just to look down on me?!

 

"DEKU!" Bakugo roared, pure, unadulterated fury overtaking his reason. Small explosions popped from his palms as he sprinted full-tilt toward Izuku. "You bastard! Tell me how you did that! WHAT DID YOU HIDE FROM ME?!"

 

Before Bakugo could reach him, Aizawa’s capture scarf whipped out, wrapping around Bakugo’s torso and pulling him taut. Aizawa’s eyes flared red, erasing the explosions. "Stand down. Don't make me use my Quirk more than I have to. I have dry eye."

 

Bakugo struggled, glaring at Izuku with a hatred so deep it chilled Izuku to the bone.

 

Kacchan... he thinks I tricked him, Izuku realized, swallowing hard.

 

 

 

The tension from the Apprehension Test carried over into the afternoon. The foundational Heroics class, taught by All Might himself, was supposed to be a fun, exciting introduction to combat.

 

Clad in his new, green rabbit-eared hero costume (courtesy of his mother), Izuku stood in the monitoring room of Ground Beta. Beside him stood Uraraka in her pink and black suit.

 

"The rules of the indoor Battle Trial are simple!" All Might announced, his booming voice echoing in the concrete room. "A villain team is guarding a nuclear weapon indoors! The hero team must infiltrate and secure the weapon or capture the villains! And our first matchup is... Team A as the Heroes, against Team D as the Villains!"

 

Izuku looked up at the screen. Team A: Midoriya and Uraraka. Team D: Bakugo and Iida.

 

Izuku felt the blood drain from his face.

 

"Oh! We're up against Bakugo!" Uraraka noted, punching her fists together. "He seems super intense, but we can take him!"

 

Izuku stared at the monitor. Bakugo wasn't just intense. Bakugo was a powder keg, and Izuku was the match.

 

Ten minutes later, Izuku and Uraraka slipped through a first-floor window of the mock building. The interior was dark, a maze of concrete pillars and tight hallways.

 

"Keep your eyes peeled, Uraraka," Izuku whispered, slipping into a defensive stance. "Kacchan won't wait for us to find the weapon. He's going to come straight for me."

 

"Are you sure?" she whispered back.

 

"Positive. He's..."

 

BOOM.

 

A massive explosion shattered the wall to their right. Concrete shrapnel and smoke flooded the hallway. Izuku reacted purely on instinct, diving and tackling Uraraka out of the blast radius. He rolled to his feet, coughing as the smoke began to clear.

 

Stepping through the rubble, his gauntlets shaped like massive grenades clanking against his forearms, was Bakugo. His hero costume was aggressive, intimidating, and perfectly suited for him. His crimson eyes locked onto Izuku, burning with a lethal intensity.

 

"Deku," Bakugo growled, his voice low and dangerous. "Don't dodge."

 

"Uraraka, go!" Izuku yelled, taking a fighting stance. "Find Iida and the weapon! I'll hold him off!"

 

"But Deku—"

 

"Go!"

 

Uraraka hesitated, then nodded, using her Quirk to make herself light and sprinting down the opposite corridor. Bakugo didn't even look at her. His target was set.

 

"So you really thought you could play me for a fool, huh?" Bakugo sneered, raising his right hand. Sparks crackled in his palm. "All those years, following me around, acting like a Quirkless loser. And all the while, you had this hidden power? You were laughing at me the whole time!"

 

"That's not true, Kacchan!" Izuku pleaded, backing up slightly. "I didn't have a Quirk! I got this power recently! It's—it's borrowed!"

 

"Borrowed?!" Bakugo roared, launching himself forward with a blast from his left hand. "Stop lying to my face!"

 

Bakugo swung a vicious right hook. Izuku, relying on his ten months of physical conditioning and martial arts studies, ducked under the blow. He grabbed Bakugo’s extended arm and used the blonde's own momentum to throw him over his shoulder, slamming him hard into the concrete floor.

 

Bakugo gasped as the wind was knocked out of him, but the shock quickly shifted back to rage. He twisted his body, firing an explosion directly into the floor to launch himself back to his feet.

 

"You read my moves!" Bakugo snarled, rubbing his back.

 

"I've been writing notes on you for years, Kacchan!" Izuku yelled back, his fists raised. "I know how you fight! You always lead with a right hook!"

 

"Then try and read this!"

 

The fight escalated into a brutal, close-quarters brawl. Bakugo was a prodigy of combat, his reflexes and instincts honed to a razor's edge. He used micro-explosions to change his trajectory mid-air, making his movements unpredictable.

 

Izuku couldn't use One For All. Even a flick in these tight quarters could collapse the building or kill Bakugo. He tried to rely purely on his physical stamina and the internal circulation of Kurama's chakra to reinforce his blocks. He deflected a kick, blocked a palm strike, but an explosion grazed his shoulder, sending him crashing through a wooden door into an abandoned office room.

 

Izuku groaned, his costume singed. He rolled to his feet just as Bakugo stalked through the doorway.

 

"You're not using it," Bakugo whispered, his voice trembling with a terrifying mix of anger and hurt pride. "You used that red monster on the entrance exam. You used it to throw the ball. But you won't use it against me. Am I not worth it, Deku? Am I too weak for you to go all out?!"

 

"No! Kacchan, you don't understand!" Izuku backed up against the far wall, his hands up in surrender. "The red power... it's dangerous! I can't control it! If I use it, I might kill you!"

 

The words hung in the air.

 

To Izuku, it was a desperate warning. To Bakugo, it was the ultimate insult.

 

He thinks he can kill me. He pities me.

 

Bakugo's face contorted into a mask of absolute, unhinged fury. He reached up, his hand gripping the pin of his massive, grenade-shaped gauntlet.

 

"Kacchan... what are you doing?" Izuku's eyes widened in terror.

 

"These gauntlets store my nitroglycerin sweat," Bakugo said, his voice eerily calm as his knuckles turned white. "When I pull this pin, it unleashes a concentrated, localized blast. If you really think you can kill me, Deku... prove it. Survive this."

 

In the monitoring room, All Might grabbed the microphone. "Young Bakugo, stop! Are you trying to kill him?! If you fire that, the match is over!"

 

Bakugo didn't even blink. "He won't die if he dodges."

 

He pulled the pin.

 

Time seemed to dilate. Izuku watched as a blinding, apocalyptic sphere of orange fire and kinetic force erupted from the gauntlet. The heat was instantaneous, vaporizing the moisture in the room. The blast wave tore up the concrete floor, heading straight for him like a tidal wave of death.

 

There was no time to dodge. There was no time to channel One For All.

 

Pure, primal terror seized Izuku’s heart. I'm going to die. He's actually going to kill me.

 

Deep within the mindscape, the massive golden cage violently shuddered.

 

Kurama had been watching the fight with mild amusement, enjoying watching the explosive brat beat some sense into his vessel. But when the gauntlet fired, the sheer lethality of the attack triggered the seal's deepest, most ancient defense mechanism.

 

The threat of imminent death forcibly cracked the seal wide open.

 

"MORTAL FOOL!" Kurama roared, his voice layered over Izuku's own as it ripped out of the boy's throat.

 

Izuku didn't raise his arms to block. He didn't cower.

 

Instead, a geyser of boiling, malevolent, blood-red chakra erupted from his core. It was ten times thicker and denser than what he had used during the ball throw. The chakra rapidly expanded, forming a massive, bubbling dome around Izuku.

 

The explosion slammed into the chakra dome. The force was enough to blow out the entire side of the building, shattering the exterior wall and sending a massive plume of smoke into the sky.

 

In the monitoring room, the students screamed. "Midoriya!"

 

The smoke in the room began to clear. Bakugo stood panting, his arm smoking from the recoil. A maniacal, breathless grin was plastered on his face. "You see that, Deku? That's what a real hero..."

 

Bakugo's voice died in his throat.

 

The smoke parted, revealing Izuku. The boy was standing, but he was no longer human.

 

The green costume was scorched, but Izuku himself was completely unharmed. He was enveloped in a thick, vibrating cloak of pure red energy. The silhouette of a demonic fox's head hovered over his own, the jaws parted in a silent scream. And behind him, thrashing violently, were not one, but two massive tails of solid red chakra.

 

Izuku's head snapped up. His eyes were entirely red—no pupils, no irises. Just glowing pools of pure malice. His lips pulled back over teeth that had elongated into jagged fangs. The fingernails on his hands had grown into dark, sharp claws.

 

The air in the room was suffocating. It smelled of sulfur, burning blood, and ancient, unadulterated rage.

 

"Deku...?" Bakugo whispered, taking an involuntary step back. His instincts, honed by years of combat, were screaming at him to run. Predator.

 

Izuku let out a sound that did not belong in the human throat. It was a guttural, multi-layered roar that shook the dust from the ceiling.

 

Then, he moved.

 

He didn't run; he dropped to all fours and launched himself forward with explosive, feral speed. The concrete beneath him cratered. Before Bakugo could even raise his hands to fire a defensive blast, Izuku was upon him.

 

A clawed hand, wreathed in boiling chakra, slammed into Bakugo's chest. The sheer kinetic force lifted the explosive blonde completely off his feet and sent him flying backward. Bakugo crashed into the concrete pillar behind him with a sickening crack, coughing up a spatter of saliva.

 

"Gah!" Bakugo gasped, his vision swimming. He tried to raise his gauntlet, to fire at point-blank range.

 

A red chakra tail whipped out like a serpent, wrapping around Bakugo’s right wrist. It squeezed, the intense heat singing the hero costume and burning the skin beneath. Bakugo cried out in pain, his fingers involuntarily opening, unable to ignite his sweat.

 

Izuku pinned Bakugo against the pillar. He straddled him, one clawed hand pressing heavily against Bakugo’s chest, the other raised high into the air.

 

Inside Izuku’s mind, there was nothing but a sea of red. The fear was gone. The anxiety was gone. It had been replaced by a violent, intoxicating, euphoric anger. It was Kurama's rage bleeding into his psyche.

 

Tear him apart, a dark voice whispered in Izuku’s mind. He tormented you. He tried to kill you. Show him what happens to those who challenge the Nine-Tails. Rip his throat out.

 

Izuku's claws sharpened. He looked down at Bakugo.

 

For the first time in his life, Katsuki Bakugo looked up at Izuku Midoriya... and he was terrified. He was completely at the mercy of a monster.

 

Izuku brought his clawed hand down.

 

"MIDORIYA, STAND DOWN! THE HERO TEAM WINS!"

 

All Might's voice exploded from the PA system, desperate and panicked.

 

At the exact same moment, the building shook. On the fifth floor, Uraraka had managed to secure the fake nuclear weapon while Iida was distracted by the explosion.

 

The words 'Hero Team Wins' pierced through the thick, bloody fog in Izuku's mind. The voice of his idol. The realization of what he was about to do.

 

Izuku’s claws stopped inches from Bakugo’s face. The glowing red eyes widened, a sliver of green returning to the center.

 

Izuku looked down at his own hand. He looked at Bakugo, who was trembling, his face pale and burned.

 

What am I doing? Izuku thought, the horror of his own actions crashing down on him. I was going to kill him. I was actually going to tear him apart.

 

"No..." Izuku gasped, his voice returning to normal, though it sounded incredibly frail. He forcefully ripped his hands away from Bakugo, stumbling backward.

 

He gripped his head, squeezing his eyes shut. Go back! Get back inside!

 

He fought the feral instinct, using every ounce of his willpower to push the dense, heavy chakra back into his core. The two tails thrashed in protest, resisting his command. But Izuku imagined the seal in his mind, wrapping chains around the red energy, and pulled.

 

With a final, hissing screech of steam, the red cloak vanished.

 

The sudden absence of the demonic energy hit Izuku's body like a freight train. The forced, rapid cell division required to maintain the Two-Tail state had completely ravaged his stamina. His skin was blistered and red from the intense heat of his own power. First-degree chakra burns covered his arms and chest.

 

Izuku let out a weak groan, his eyes rolling back in his head. He collapsed onto the ruined concrete floor, unconscious.

 

Bakugo slid down the pillar, his breathing ragged. He stared at the unconscious boy, his pride utterly and completely shattered.

 

 

 

Drip.

 

Splash.

 

Izuku awoke slowly. The familiar scent of rust and moss filled his nose. He didn't open his eyes immediately. He just lay in the shallow water, the phantom heat of the Two-Tail cloak still prickling his skin.

 

He slowly sat up.

 

Kurama was waiting. The colossal fox was not resting. He was sitting upright behind the golden bars, his nine tails swaying in a slow, hypnotic rhythm. His crimson eyes stared down at the boy, unreadable.

 

"I almost killed him," Izuku whispered, his voice trembling. He looked at his hands, expecting to see claws. Just human fingers. "I felt it. I felt the urge to just... tear him apart. It felt good. It felt so good to finally hurt him back."

 

Izuku hugged his knees to his chest, shivering. "Am I a monster?"

 

"You tapped into my chakra to save your own miserable life," Kurama said, his voice unusually subdued, lacking its typical venom. "When you draw upon my power forcefully, you also draw upon my consciousness. My hatred. My rage. It is a potent weapon. But it is poison to a mortal mind."

 

Kurama lowered his massive snout until it was level with Izuku. "Listen to me, brat. That anger is a crutch. If you rely on my rage to fight your battles, it will consume you entirely. You will lose your mind, and you will become nothing more than a rabid beast. A puppet for my power."

 

Izuku looked up at the giant, terrifying demon. He didn't see a monster. He saw a prisoner who knew the exact cost of unchecked power.

 

Slowly, Izuku stood up. He walked toward the cage, splashing through the water, until he was just inches from the golden bars.

 

He didn't yell. He didn't cry. Instead, he placed his hands on his knees and bowed deeply, a perfect, ninety-degree angle of absolute respect.

 

Kurama blinked, taken aback. "What are you doing, fool?"

 

"I'm thanking you," Izuku said softly, remaining bowed. "You saved my life again. You gave me your power when I was about to be blown up. And... I'm sorry."

 

"Sorry for what?"

 

Izuku stood up, looking directly into the giant red eyes. "For pulling on your power without asking. For treating you like a tool when I panicked. You're right. Your anger isn't mine to use. I promise... I will communicate better. I won't demand your power. I want us to work together."

 

Kurama stared. In the centuries he had lived, since the days of the Sage of Six Paths, humans had only ever viewed him in two ways: as a natural disaster to be feared, or as a weapon of mass destruction to be enslaved. Even the previous vessels of his bloodline had treated him with either terror or greed.

 

Never, not once, had a human bowed to him in genuine gratitude. Never had a human apologized for using him.

 

"You are an anomaly, meat-sack," Kurama finally muttered, turning his head away to hide the slight shift in his demeanor. "Do not mistake my warnings for care. I merely do not wish to be sealed inside a mindless beast."

 

Izuku smiled warmly. It was a genuine, bright smile that seemed to slightly illuminate the dark mindscape. "I know. But we're stuck together. So we might as well be partners. Oh, by the way... I can't keep calling you 'giant fox' or 'monster' in my head. You said your name before, but I was so tired I barely remember."

 

Izuku placed a hand against the cold, golden iron of the cage. "What's your name?"

 

Kurama looked back at the boy. He saw the green eyes, completely devoid of fear, malice, or greed. Just pure, heroic sincerity.

 

The giant fox huffed, a small puff of smoke escaping his lips.

 

"Kurama," the ancient beast rumbled. "My name is Kurama. Remember it, brat. Because one day, I will make you beg for my power again."

 

"Kurama," Izuku tested the name on his tongue. He smiled wider. "It's nice to officially meet you, Kurama."

 

Izuku began to fade from the mindscape, the real world pulling his consciousness back to the infirmary bed.

 

As the boy vanished, the sewer fell silent once more. Kurama rested his chin on his paws, looking at the spot where the boy had stood.

 

"A partner, huh?" Kurama mused quietly to himself. The colossal tails swished slightly in the water. "We'll see, Izuku. We'll see."

 

In the U.A. infirmary, Izuku opened his eyes to the sterile white ceiling. His body ached terribly, coated in burn salve and bandages. But as he looked at his right hand, he felt a strange sense of peace.

 

He had the incredible, bone-breaking power of the Number One Hero in his right arm. And he had the terrifying, ancient, furious power of a demonic fox coiled in his stomach.

 

Two absolute, overwhelming powers. Two massive responsibilities.

 

I'm not Quirkless anymore, Izuku thought, clenching his bandaged fist. I'm the vessel for the two strongest powers in the world. And I'm going to master them both.
