What If Deku Had an Infinite Quirk That's Broken

 

The scent of sterile alcohol wipes, stale waiting-room coffee, and the faint, metallic tang of ozone always accompanied the memories of that day.

 

Izuku Midoriya was four years old. He sat on a crinkling paper sheet draped over a faux-leather examination table, his short legs dangling over the edge, kicking rhythmically against the cabinet below. Thump. Thump. Thump. He was wearing his favorite t-shirt, the one with All Might’s Golden Age silhouette emblazoned across the chest in vibrant reds and blues. To anyone else, Izuku looked like the quintessential modern child: bright-eyed, bushy-haired, and practically vibrating with the suppressed, nervous energy of someone about to receive the keys to their future.

 

In a world where eighty percent of the population possessed a superhuman ability known as a Quirk, reaching the age of four was a milestone akin to a second birth. It was the age of manifestation. The age of awakening. It was the moment a child discovered whether they would breathe fire, manipulate gravity, speak to animals, or possess the strength to lift a bus. For Izuku, whose entire existence revolved around hero analysis notebooks, All Might merchandise, and the fervent dream of standing in the sun with a fearless smile, today was supposed to be the best day of his life.

 

Beside him, his mother, Inko Midoriya, sat in a hard plastic chair, wringing her hands in her lap. She was a slender woman then, with soft green hair that matched her son’s, and eyes that constantly radiated a gentle, maternal warmth. Yet, beneath that warmth, a faint undercurrent of anxiety rippled. Most children showed signs of their Quirks by now. Katsuki Bakugo, Izuku’s best friend—or at least, his closest proximity companion—had already started popping tiny, caramel-scented explosions from his palms. Other kids at preschool were stretching their limbs, changing colors, or floating blocks.

 

Izuku had done none of that.

 

He hadn't breathed fire like his father, Hisashi, nor had he shown the ability to attract small objects like his mother. He was perfectly, concerningly mundane.

 

"Mom?" Izuku’s voice was a soft, melodic chirp in the quiet room. "Do you think my Quirk will be flashy like Kacchan’s? Or maybe I'll get super strength! If I get super strength, I can save everyone with a smile, just like him!" He pointed to the poster of All Might pinned to the back of the clinic door.

 

Inko offered a wobbly, encouraging smile, reaching out to brush a wild curl from his forehead. "I'm sure whatever your Quirk is, Izuku, it will be wonderful. But remember what we talked about? Even if it's not a flashy fighting Quirk, you can still be a hero in your own way. You have such a big heart, my sweet boy."

 

She was preparing him. A mother’s intuition, attempting to cushion the blow of a potential 'Quirkless' diagnosis.

 

The door handle clicked, turning downwards with a sharp metallic clack, and Dr. Tsubasa walked in. He was a rotund man with an impressive, bushy mustache and thick, round goggles that magnified his eyes, giving him the appearance of a perpetually surprised owl. He carried a clipboard tucked under his arm and offered a warm, practiced smile.

 

"Ah, the Midoriyas! Apologies for the wait," Dr. Tsubasa said, his voice booming in the small room. He moved to the sink to wash his hands. "So, young Izuku is here to find out why the fireworks haven't started yet, eh?"

 

"Yes, Doctor," Inko replied, her voice tightening slightly. "He hasn't shown a single sign. No fever, no accidental activations, nothing. We thought it best to bring him in for the joint x-ray and genetic screening."

 

"A wise choice, Mrs. Midoriya. It’s standard procedure," the doctor reassured her, drying his hands on a paper towel. "We usually check the pinky toe joint first. Evolutionary biology tells us that individuals who lack the extra joint in their pinky toe represent the next stage of human evolution—the Quirked population. It's a simple, painless x-ray. If the joint is missing, we know a Quirk is present, and it's just a matter of a late blooming or a psychological block. If the joint is there... well, we cross that bridge if we come to it."

 

He turned to Izuku, leaning down to meet the boy's wide, emerald eyes. "Are you ready, young man? We're going to take a special picture of your foot. It won't hurt a bit."

 

Izuku nodded eagerly, his curls bouncing. "I'm ready! I want to be a hero!"

 

Dr. Tsubasa chuckled, a rich, rumbling sound. "I love that spirit. Let's get you over to the machine."

 

The doctor guided Izuku to a corner of the room where a standard medical X-ray machine stood. It was a bulky, imposing piece of equipment, painted in dull medical gray. Dr. Tsubasa instructed Izuku to sit on the edge of the lead-lined table and place his bare left foot onto the designated plate.

 

"Now, just hold very still, Izuku. Don't wiggle your toes," the doctor instructed, stepping behind a protective lead-glass screen a few feet away. He adjusted the dials, calibrating the machine for a pediatric scan.

 

"Okay, Doctor," Izuku chirped, staring intently at his own foot, determined to be the best patient ever.

 

Behind the glass, Dr. Tsubasa pressed the activation button.

 

Click. Whirrrrrrr.

 

The machine powered up, the familiar hum of the generator filling the room. The cathode tube began to emit the brief burst of electromagnetic radiation designed to pass through the soft tissue and map the dense bone structure of Izuku’s foot.

 

Then, the world seemed to stutter.

 

It wasn't a physical sensation, but rather a profound, sickening drop in the atmosphere, like the sudden shift in cabin pressure on an airplane plummeting a thousand feet in a second. The fluorescent lights overhead flickered wildly, buzzing with an angry, aggressive static.

 

From the X-ray machine, a sound emanated that Dr. Tsubasa had never heard in his thirty years of medical practice. It wasn't the sound of a blown fuse or a mechanical failure. It sounded like... screaming metal. A high-pitched, harmonic whine that drilled into the eardrums.

 

BZZZZT—KRRK—POP!

 

Sparks showered from the back of the imaging console. The heavy, reinforced glass of the machine's emitter tube—designed to withstand immense heat and radiation—shattered inward, imploding with a violent crunch. A localized shockwave of displaced air blasted outward, rustling Inko’s dress and knocking the clipboard off the counter.

 

"Izuku!" Inko shrieked, bolting from her chair toward her son.

 

"Hold on, stay back!" Dr. Tsubasa yelled, scrambling out from behind the screen. He quickly hit the emergency power kill switch on the wall. The room plunged into the dim, natural light filtering through the window blinds, leaving only the smell of burnt copper and ozone hanging thick in the air.

 

Izuku hadn't moved. He sat perfectly still, his foot resting on the now-ruined imaging plate, his large green eyes blinking in confusion. He was entirely unharmed. Not a single shard of glass had touched him. In fact, if one looked closely, there was a perfect, microscopic ring of completely undisturbed dust circling his foot, as if the concussive force of the implosion had simply... decided not to exist in his immediate vicinity.

 

"I didn't wiggle, Doctor," Izuku whispered, his voice trembling slightly, fearful that he had done something wrong and ruined his chances.

 

Dr. Tsubasa stood frozen, his heart pounding in his chest. He looked from the boy to the smoking, twenty-thousand-dollar piece of medical equipment. "Are... are you hurt, son?"

 

"No," Izuku said softly.

 

Inko reached the boy, pulling him into a desperate hug, checking him over frantically. "Oh my god, Izuku, are you alright? Doctor, what happened?! Did the machine malfunction?"

 

Dr. Tsubasa pushed his goggles up, rubbing his forehead. He was a man of science. Machines broke. Fuses blew. But the way the emitter tube had imploded—it didn't look like a standard mechanical failure. It looked as though the radiation the machine had attempted to project onto the boy's foot had hit a wall of absolute, impenetrable density, and the resulting feedback loop had violently shoved the energy backward into the machine itself.

 

"I... I don't know," Dr. Tsubasa admitted, his voice shaken. "The power surge must have been massive. The entire localized grid in this room just shorted." He took a deep breath, trying to regain his professional composure. "Let's... let's move away from the machine. I'm so sorry, Mrs. Midoriya. It seems we won't be able to get an x-ray today."

 

Inko held Izuku tight against her side. "Then how will we know? About his Quirk?"

 

Dr. Tsubasa frowned, walking over to his desk and pulling open a drawer. "There is another way. It’s a bit more invasive, which is why we don't start with it for children, but we can do a genetic blood draw. By analyzing the boy's DNA sequence, the lab can identify the presence of the Plus Alpha gene, which is responsible for Quirk manifestation. If the gene is there, we know he has a Quirk, even if we don't know what it is yet."

 

He pulled out a sealed, sterile syringe, a rubber tourniquet, and an alcohol swab.

 

Inko looked down at Izuku. "Are you okay with a little poke, sweetie? It'll just feel like a pinch."

 

Izuku, still reeling from the exploding machine but desperate for answers, nodded bravely. "I'm okay, Mom. Heroes don't cry from needles."

 

Dr. Tsubasa smiled, though it was strained. "Brave boy."

 

He instructed Inko to hold Izuku in her lap. The doctor pulled his rolling stool over, snapping on a pair of fresh latex gloves. He took Izuku’s small, fragile left arm, expertly tying the rubber tourniquet around the bicep to make the veins in the crook of the elbow stand out. He swabbed the soft, pale skin with alcohol.

 

"Alright, Izuku. Look at your mother for me. Count to three," the doctor said smoothly, uncapping the syringe. The needle was thin, surgical steel, designed to slide seamlessly into the flesh.

 

"One," Izuku started, staring at his mother's worried face.

 

Dr. Tsubasa lined up the needle with the vein. He applied a gentle, practiced pressure, pushing the tip of the steel toward the boy's skin.

 

"Two," Izuku said.

 

The tip of the needle made contact with Izuku’s arm.

 

Or, rather, it didn't.

 

Dr. Tsubasa felt a strange sensation. The needle stopped. It didn't pierce the skin. It didn't even indent the flesh. It felt as though he had suddenly pressed the needle against a solid slab of diamond. Confused, he applied a fraction more pressure.

 

"Three," Izuku finished, waiting for the pinch.

 

It never came.

 

Dr. Tsubasa frowned, leaning closer. The tip of the needle was resting exactly one millimeter above the epidermis of Izuku’s arm. The doctor pushed harder. His knuckles turned white beneath the latex. The syringe trembled in his grip.

 

Nothing. The skin did not yield. The needle did not move forward.

 

"Doctor? Is something wrong?" Inko asked, noticing the man’s sudden, intense concentration and the slight tremor in his hand.

 

"Just a tough vein," Dr. Tsubasa muttered, though sweat was beginning to bead on his forehead. This was impossible. Human skin, even mutated skin hardened by a durability Quirk, would show signs of resistance—indentation, discoloration. This was different. The space between the needle and the skin felt... insurmountable.

 

Frustrated, and deeply unsettled by the lingering adrenaline from the exploding X-ray machine, the doctor made a mistake. He pushed with significant, forceful effort, driving the needle downward with the strength of his entire arm.

 

What happened next would haunt Dr. Tsubasa for the rest of his medical career.

 

He watched, through the magnifying lenses of his goggles, as the laws of physics shattered on the arm of a four-year-old boy.

 

The surgical steel needle, unable to pierce the invisible barrier resting a millimeter above Izuku’s skin, had nowhere to go. Under the doctor's force, the metal began to bend. But it did not snap. It did not buckle to the side.

 

Instead, the metal began to curl inward on itself. As the doctor applied kinetic energy, pushing forward, the space between the needle and the skin reacted by mathematically multiplying the distance. To the naked eye, the needle seemed to hit a wall, but on a microscopic level, the needle was traveling through an infinitely expanding fraction of space.

 

Because the tip could not move forward, the kinetic energy had to disperse. The steel of the needle began to compress. It accordioned, flattening, folding, and curling into a microscopic, infinitely dense spiral of metal.

 

Dr. Tsubasa gasped, yanking his hand back as if he had been burned.

 

He stared at the syringe in his hand. The long, sharp needle was gone. In its place, at the plastic tip of the syringe, was a tiny, flat, perfectly smooth disc of steel, no larger than the head of a pin. The needle hadn't broken. It had been compressed—crushed by a spatial anomaly into a dense, solid mass.

 

The doctor dropped the syringe. It clattered against the linoleum floor with a heavy, unnatural thud.

 

Dr. Tsubasa stumbled backward, his rolling stool catching on the floor, sending him crashing onto his back. He scrambled away, pressing himself against the far wall of the examination room, his chest heaving, his eyes wide with a primal, instinctual terror.

 

"Doctor!" Inko cried out, completely bewildered by the man's sudden panic. She hadn't been able to see the microscopic distortion of the needle. All she saw was the doctor failing to draw blood and then collapsing in fear. "What is it?! What's wrong with him?!"

 

Dr. Tsubasa was hyperventilating. He looked at Izuku. The boy was looking back at him, head tilted, eyes wide with innocent concern. The boy was a void. A paradox sitting in a medical gown.

 

"What... what is he?" Dr. Tsubasa stammered, pointing a trembling finger at the four-year-old.

 

"He's my son!" Inko snapped, her maternal protective instincts flaring up, her voice sharp and angry. "What is wrong with you? Explain yourself!"

 

Dr. Tsubasa slowly pulled himself up, using the edge of the sink for support. He took off his goggles, wiping a thick layer of cold sweat from his face. His mind, trained in biology, genetics, and the varied, often bizarre nature of Quirks, raced to categorize what he had just witnessed.

 

Quirks fell into three categories: Emitter, Transformation, and Mutant. They operated on the laws of physics, even when they bent them. Fire required oxygen and fuel (usually lipids). Gravity manipulation required physical contact and drained stamina. Everything had a cost. Everything had an equivalent exchange.

 

But this... this was a violation.

 

The X-ray machine hadn't just broken. The radiation had hit a barrier of infinite density and reflected back. The needle hadn't just bent. It had traveled through an infinitely recurring space and compressed itself to the atomic level.

 

"Mrs. Midoriya," Dr. Tsubasa whispered, his voice hoarse. "I have seen thousands of Quirks. I have seen children who can sweat acid, who can manipulate time for three seconds, who can turn their skin into steel. But all of them... all of them obey a limit."

 

He swallowed hard, looking at Izuku, not with the warmth of a pediatrician, but with the cautious dread of a man standing before a live nuclear warhead.

 

"Your son... he doesn't have a biological Quirk. Not in the traditional sense."

 

"Then what does he have?" Inko demanded, clutching Izuku so tightly the boy gave a small squeak.

 

Dr. Tsubasa walked slowly toward his desk, keeping a wide berth around the boy. He pulled out a medical file, his hands shaking so violently he could barely hold the pen.

 

"I cannot officially diagnose this without a specialized, top-secret government facility," Dr. Tsubasa said, writing frantically. "But if my theory is correct... your son possesses a Conceptual Quirk. A reality-warping anomaly."

 

"A what?" Inko asked, her anger giving way to deep confusion and a rising, icy fear.

 

"I don't know what the trigger is. I don't know how it operates," Dr. Tsubasa said, looking up, his eyes grave. "But when I tried to pierce his skin, the space between the needle and his arm didn't just resist. It became infinite. The needle would have had to travel across an eternity of space just to touch his epidermis."

 

He set the pen down. "Your son’s Quirk... is the concept of Infinity."

 

The word hung in the air, heavy and suffocating.

 

Infinity.

 

"What... what does that mean?" Inko asked, her voice shrinking to a frightened whisper.

 

"It means," Dr. Tsubasa said slowly, "that there is no limit. If he generates heat, it might never stop heating. If he applies force, it might never stop pushing. The laws of thermodynamics, of spatial reality... they break around him."

 

The doctor took a step closer, his expression pleading. "Mrs. Midoriya. You must listen to me. This is not a gift. It is a mathematical paradox housed in a human body. He is four years old. If he throws a tantrum and accidentally applies infinite kinetic energy to the floor... he won't just break the floor. He could shatter the tectonic plate."

 

Inko stopped breathing. The color drained entirely from her face. She looked down at Izuku, her sweet, innocent baby boy, who was looking up at her with tears welling in his eyes. He didn't understand the big words, but he understood the tone. He understood that he was a monster in this man's eyes.

 

"Mom?" Izuku whimpered. "Am I bad?"

 

"No!" Inko sobbed, dropping to her knees and burying her face in Izuku’s shoulder, crying desperately. "No, Izuku, you're perfect. You're my perfect boy."

 

She stood up, hoisting Izuku into her arms, shooting Dr. Tsubasa a look of pure, venomous defiance. "We are leaving. We will not be returning to this clinic."

 

"Mrs. Midoriya, wait!" Dr. Tsubasa called out, but she was already out the door, her heels clicking rapidly down the hallway.

 

The doctor stood alone in the ruined examination room, the smell of ozone still lingering. He looked at the crushed needle on the floor, and a cold shiver ran down his spine. He walked over, picking it up with a pair of tweezers, and sealed it in a biohazard bag. He needed to make a phone call. The Hero Public Safety Commission needed to know that a god had just been born in Musutafu.

 

 

 

The drive home was suffocatingly quiet.

 

Usually, the small, boxy sedan would be filled with the sound of the radio, or Izuku chattering endlessly about whatever hero fight he had seen on the news that morning. Today, there was only the hum of the engine and the rhythmic thrum, thrum, thrum of the tires on the asphalt.

 

Inko gripped the steering wheel so tightly her knuckles were white. Her eyes were fixed rigidly on the road, though they were glossy with unshed tears. Her mind was a whirlwind of panic, denial, and fierce, primal protectiveness.

 

Infinity. A reality-warping anomaly. He could shatter the tectonic plate.

 

The doctor’s words echoed in her skull, a horrifying mantra. She glanced in the rearview mirror. Izuku was strapped into his booster seat in the back. He was looking out the window, his expression unusually vacant, his small hands resting flat on his knees. He looked so small. So fragile.

 

How could a boy who cried when he scraped his knee be capable of ending the world?

 

It was a mistake. It had to be a mistake. The doctor was a quack. The machine was faulty, and the needle was a cheap, defective product. That had to be it. Her Izuku was normal. He would grow up, get a normal, safe Quirk, maybe go to a regular high school, become a police officer or an accountant. He would be safe.

 

But deep down, in the pit of a mother’s soul, Inko knew the doctor was right. She had felt it. In that room, when the needle stopped, the air had grown heavy. The hair on her arms had stood up. It was the biological response of a mortal creature in the presence of something completely incomprehensible.

 

"Mom?"

 

Inko jumped slightly at the sound of Izuku’s voice. "Y-yes, sweetie? What is it?"

 

"The doctor said I have a Quirk," Izuku said softly, still staring out the window at the passing city.

 

"Yes, honey. He... he did."

 

"But he looked scared of me." Izuku turned his head, his wide green eyes meeting hers in the mirror. There was a depth in those eyes now, a sudden, jarring maturity that had not been there an hour ago. The innocence was fracturing, replaced by the terrifyingly sharp analytical mind that Izuku had always possessed, now turned inward. "Why was he scared of my Quirk, Mom?"

 

Inko choked on a sob, quickly rolling down the window to let the cold air hit her face. "He wasn't scared of you, Izuku. He was just... surprised. Your Quirk is very special. It's very strong."

 

"Like All Might's?"

 

The question broke her heart. "I... I don't know, Izuku. We're going to have to figure it out together, okay? But you have to promise me something."

 

"What?"

 

"You have to be very, very careful," Inko said, her voice dropping to a serious, pleading register. "You can't use it yet. Not until we know how it works. You can't use it when you're angry, or when you're playing. You have to keep it inside. Can you promise Mommy that?"

 

Izuku looked at his hands. Small, chubby, perfectly normal hands.

 

"I promise, Mom."

 

They arrived at their apartment complex. Inko rushed them inside, locking the door behind them as if trying to shut out the world. She told Izuku to go play in his room while she started making dinner. She needed a moment to breathe, to call Hisashi, to figure out what to do.

 

Izuku walked down the short hallway to his bedroom. He pushed the door open. The room was a shrine to his idol. Posters of All Might covered the walls. Action figures lined the shelves. A limited-edition Golden Age All Might bedsheet covered his mattress. Usually, walking into this room filled him with a bubbling, effervescent joy.

 

Today, it felt hollow.

 

Izuku walked over to his toy box. He reached in and pulled out his favorite action figure—the Silver Age All Might with the poseable arms and the built-in voice box. He held it in his hands, staring at the painted-on smile.

 

I am here! the voice box would declare if pressed.

 

Izuku didn't press it. He walked over to his small desk and climbed into the chair. He sat there in silence, a four-year-old trying to process the concept of Infinity.

 

He didn't fully understand the math, or the physics. But he understood the feeling. He remembered sitting on the examination table. He remembered the blinding flash of the machine. He remembered the feeling in his chest—a sudden, rushing sensation, like a dam holding back an ocean of pressure, completely under his subconscious control.

 

He had stopped the radiation because he hadn't wanted it to touch him. He had stopped the needle because he hadn't wanted the pinch.

 

It wasn't a physical action. It was a choice. He had willed the space to exist, and the universe had obeyed.

 

Izuku looked down at the All Might figure in his hand. He was holding it loosely. Too loosely.

 

His fingers slipped. The plastic toy tumbled from his grasp, falling toward the hardwood floor.

 

It was a mundane accident. A child dropping a toy. It happened millions of times a day across the world.

 

But Izuku Midoriya was not a normal child. And the trauma of the clinic had left his newly awakened Quirk humming just beneath the surface of his skin, raw and unregulated.

 

As the toy fell, Izuku’s mind reacted instantly. No, don't drop it. Stop it.

 

He reached out his hand, palm open, fingers splayed. He didn't physically catch the toy. He simply targeted the object with his will, accessing that deep, terrifying well of power within his chest.

 

He applied the concept of 'Halt'.

 

He wanted the toy to stop falling. He applied kinetic energy to counteract gravity, pushing upward against the toy to hold it in the air.

 

Click.

 

The sensation was instantaneous and nauseating. The air in the bedroom warped, a visible distortion rippling outward like heat haze off a summer road. A sound, low and resonant, vibrated in Izuku’s teeth. It was the sound of reality groaning under an impossible equation.

 

The All Might toy stopped mid-air, exactly halfway between Izuku’s hand and the floor.

 

It didn't bounce. It didn't sway. It froze, locked perfectly in spatial suspension.

 

Izuku gasped, a smile breaking out on his face. I did it! I have telekinesis like Mom!

 

But the smile lasted only a fraction of a second.

 

Izuku had not applied a specific amount of force to hold the toy. He did not know how to modulate his output. His Quirk was 'Infinity'. By engaging it, he had opened a floodgate that had no physical bottom.

 

He wasn't just holding the toy. He was pouring infinite kinetic energy into the plastic structure to oppose the force of gravity.

 

Gravity pulls at 9.8 meters per second squared. Izuku was pushing upward with an escalating force of ten, then a hundred, then a million, then a billion, then a trillion newtons of force, expanding endlessly every microsecond.

 

The toy could not move upward, because Izuku’s command was 'Halt', not 'Lift'. The energy had nowhere to go. It became trapped within the physical matter of the object.

 

The plastic All Might figure began to vibrate.

 

It started as a low hum, then escalated into a violent, screeching blur. The painted smile distorted. The plastic began to glow, first a dull red, then a blinding, incandescent yellow as the friction of its own atoms, supercharged with infinite kinetic energy, generated impossible levels of heat.

 

The air around the toy ignited into plasma.

 

Izuku screamed, stumbling back from his desk, falling hard onto the floor. He squeezed his eyes shut and threw his hands over his head, screaming internally for it to stop, stop, stop!

 

He severed the connection. He slammed the mental floodgate shut.

 

CRACK.

 

A sound like a localized thunderclap shattered the silence of the bedroom. A shockwave of displaced, superheated air blasted outward, shattering the glass of Izuku’s bedroom window, blowing the posters off the walls, and knocking the wind out of the boy's lungs.

 

Inko burst into the room a second later, wielding a frying pan, her face pale with terror. "Izuku! What happened?! Are you hurt?!"

 

She stopped dead in her tracks.

 

The room was a mess. Papers were everywhere. The window was blown out, cold wind whipping the curtains. Izuku was huddled on the floor against the bed, trembling violently, his hands over his ears, tears streaming down his face.

 

And in the center of the room, just above the floor where the toy had been... there was nothing.

 

No, not nothing. There was a faint, glowing ember of ash drifting to the ground. A microscopic dusting of carbon. The hardwood floor beneath the spot was charred black in a perfect circle.

 

The All Might figure hadn't melted. It hadn't exploded. It had been subjected to so much energy in the span of two seconds that its molecular bonds had completely failed. It had been atomized. Erased from existence.

 

Inko dropped the pan. She fell to her knees and crawled to her son, wrapping him in her arms, rocking him back and forth as he sobbed uncontrollably.

 

"I'm sorry!" Izuku wailed, clutching his mother's shirt. "I'm sorry, Mom! I just wanted to catch it! I didn't mean to! I didn't mean to break it!"

 

Inko stared at the scorch mark on the floor. The terrifying reality of Dr. Tsubasa's words settled heavily onto her shoulders, a crushing, suffocating weight. Her son wasn't just powerful. He was a force of nature. A cosmic error housed in the body of a weeping four-year-old.

 

"Shh, shh," Inko hushed him, her own tears falling into his green curls. "It's okay, baby. It's okay. We just... we have to learn. We have to be so, so careful."

 

Izuku buried his face in her chest. Through his tears, his hyper-analytical mind was already processing the data. He hadn't felt tired. He hadn't felt strain. He had just wanted the toy to stop falling, and the universe had obeyed so violently it destroyed the object.

 

He realized, with the cold, horrifying logic that only a traumatized child can muster, that he was dangerous. He was fundamentally, irreparably broken.

 

He was a sledgehammer. And everything around him—his toys, his room, his mother—was made of the thinnest, most fragile glass.

 

 

 

Months passed.

 

The incident in the bedroom was never spoken of again, but it fundamentally altered the trajectory of Izuku Midoriya's life.

 

At four and a half years old, Izuku stopped being a child.

 

He stopped running. He stopped yelling. He stopped throwing tantrums. When he walked, he placed his feet on the ground with extreme, deliberate care, as if testing the floorboards to ensure they wouldn't collapse into a singularity beneath him. When he closed doors, he used precisely enough force to click the latch, terrified that a momentary lapse in concentration would send the door flying through the wall.

 

He became quiet. Withdrawn. He sat in the back of his preschool class, his green eyes constantly scanning the room, analyzing the trajectories of the other children, the structural integrity of the desks, the distance between himself and any potential accident.

 

He was building a mental fortress. A cage of absolute, unyielding control to house the infinite beast that slept in his chest.

 

This drastic change in personality did not go unnoticed, especially by the loud, brash, explosively arrogant king of the playground: Katsuki Bakugo.

 

Katsuki had gotten his Quirk early. Explosion. He could sweat nitroglycerin and ignite it on command. It was flashy, powerful, and perfectly suited for a future Number One Hero. Katsuki reveled in it. He thrived on the praise of the teachers and the awe of his peers. He was the apex predator of the sandbox.

 

And previously, Izuku—or 'Deku', as Katsuki had affectionately, then mockingly, dubbed him—had been his loyal shadow. Deku was supposed to be the awe-struck follower, the Quirkless loser who looked up to Katsuki’s brilliance.

 

But Deku had changed.

 

He didn't follow Katsuki around anymore. He sat on the swings, alone, watching the world with eyes that looked too old, too tired. It pissed Katsuki off. It felt like defiance. It felt like a challenge to his authority.

 

It was a crisp autumn afternoon. The playground was filled with the sounds of screaming children, crunching leaves, and the occasional pop-pop-pop of Katsuki showing off his Quirk to his lackeys.

 

Izuku was sitting on the edge of the sandbox, drawing in a notebook. He was cataloging the structural limits of concrete versus steel, a morbid hobby he had developed to distract his mind.

 

Katsuki stomped over, his two followers trailing behind him like remoras on a shark.

 

"Hey, Deku!" Katsuki barked, kicking sand onto Izuku’s shoes. "What are you doing sitting over here by yourself like a weirdo? Why aren't you watching me? I just blew up a whole pile of rocks!"

 

Izuku looked up. His expression was flat, completely devoid of the hero-worship Katsuki was accustomed to. "Hello, Kacchan. That sounds nice. I'm just reading."

 

Katsuki bristled. The casual, unimpressed tone was a slap in the face. "You think you're better than me now? Just because you finally got your Quirk? I heard your mom tell my mom. You got some weird, useless telekinesis thing, right? Bet it's nothing compared to mine!"

 

Katsuki wanted a reaction. He wanted Deku to cower, or to cry, or to try and fight back so Katsuki could put him in his place.

 

Katsuki raised his right hand, letting off a series of miniature explosions that crackled and smoked in his palm. He took a threatening step forward, intending to push Izuku off the edge of the sandbox with an explosive shove to the shoulder. Just a warning shot. To establish the pecking order.

 

"Watch it, Deku, or I'll blast you to—!"

 

Katsuki thrust his hand forward.

 

He never made contact.

 

As Katsuki’s palm moved toward Izuku’s shoulder, Izuku didn't flinch. He didn't blink. His mind, operating on a hyper-vigilant defense protocol he had spent months perfecting, reacted on pure instinct.

 

Danger. Threat incoming. Distance: 10 inches. Modulate space.

 

Izuku engaged his Quirk. He didn't apply kinetic energy this time. He applied a spatial concept. He took the ten inches of space between his shoulder and Katsuki’s hand, and he looped it.

 

To the outside observer, nothing happened. Katsuki thrust his hand forward, and his hand just... stopped in mid-air, an inch away from Izuku's shirt.

 

But Katsuki felt it.

 

He pushed against the air, hard. His arm strained, his muscles flexing. But his hand wouldn't move forward. It felt like he was pushing against a solid wall of invisible rubber. Frustrated, Katsuki triggered a larger explosion from his palm, right in Izuku’s face.

 

BOOM!

 

Smoke and fire erupted from Katsuki's hand.

 

But the fire didn't touch Izuku. The concussive wave didn't ruffle a single strand of his green hair.

 

Instead, the explosion hit the invisible spatial loop. The kinetic force and the heat of the blast traveled forward into the infinitely folded pocket of space, spiraling endlessly inward, traveling millions of miles within a microscopic boundary, until it simply dissipated into nothingness. The sound of the blast was muffled, instantly swallowed by the void.

 

The smoke cleared. Izuku was still sitting there, completely unharmed, staring up at Katsuki with those deep, ancient green eyes.

 

Katsuki froze.

 

The human brain is wired by millions of years of evolution to recognize predators. We fear the dark, we fear heights, we fear the roar of a lion, because our ancestors who feared those things survived.

 

When Katsuki Bakugo looked into Izuku Midoriya's eyes at that moment, an evolutionary alarm bell, buried deep in his primal lizard brain, began to ring with deafening intensity.

 

He didn't understand what he was looking at. He didn't understand the physics or the reality-warping math.

 

But he understood power. And he understood that the power sitting in front of him did not care about him. It did not care about his explosions, his arrogance, or his existence. It was a black hole wearing the skin of a five-year-old boy.

 

If Deku wanted to, Katsuki realized with a sudden, horrifying clarity, Deku could end him. Not beat him in a fight. Not burn him or punch him. Erase him.

 

The air around Izuku felt cold. Heavy. The static electricity raised the hair on Katsuki's arms.

 

Katsuki stumbled backward, yanking his arm away as if the air itself had burned him. He fell onto his backside in the sand, his breath hitching in his throat. His red eyes were wide with unadulterated, instinctual terror.

 

"K-Kacchan?" one of his lackeys stammered, confused by the sudden retreat. "What happened? Did he do something?"

 

Katsuki didn't answer. He couldn't take his eyes off Izuku. His hands were shaking. The explosive sweat on his palms felt completely, laughably inadequate.

 

Izuku slowly closed his notebook. He looked at Katsuki shivering in the sand, and he felt a profound, crushing sorrow.

 

He didn't want this. He didn't want to be feared. He just wanted to be a hero. He wanted to save people with a smile, like All Might.

 

But how could he save people when his mere existence terrified his best friend into silence? How could he be a symbol of peace when he was, by definition, a weapon of mass destruction?

 

"I'm sorry, Kacchan," Izuku said softly, his voice devoid of emotion, a necessity to maintain his mental cage. "I didn't mean to scare you. I won't hurt you. I promise."

 

Izuku stood up, brushed the sand off his shorts, and walked away, leaving Katsuki trembling in the dirt.

 

From that day on, the bullying ceased.

 

Katsuki Bakugo never pushed Izuku again. He never mocked him. He never called him useless. Instead, he avoided him. He gave Izuku a wide berth in the classroom, in the hallways, in the streets. When their eyes met, Katsuki would quickly look away, the phantom memory of that infinite void chilling his blood.

 

The rest of the children, sensing the shift in dynamics—seeing the fearless Katsuki Bakugo actively avoid the quiet, green-haired boy—followed suit. Izuku became a ghost in his own life. Untouchable. Unapproachable.

 

Alone.

 

 

 

That evening, a five-year-old Izuku Midoriya sat on the roof of his apartment building.

 

It was dangerous for a child to be up here, but Inko was exhausted from a double shift, asleep on the couch, and Izuku needed to see the sky. He needed to see space.

 

He sat with his legs dangling off the edge, looking down at the sprawling, glowing city of Musutafu. The streetlights twinkled like fallen stars. Cars moved like little blood cells through the concrete arteries of the city. People, tiny and insignificant, hurried about their lives.

 

Eighty percent of them had power. They could create water, manipulate shadows, harden their skin, fly. They thought they were gods in their own right. They built a society around their powers, creating a binary world of Heroes and Villains, good and evil, strong and weak.

 

Izuku looked down at his small hands.

 

He opened his right hand. He focused on a single, dead leaf resting on the tar-paper roof beside him.

 

Target. Isolate. Concept: Nullify Friction.

 

He didn't touch the leaf. He simply looked at it and altered the mathematical constant of the universe interacting with its surface.

 

A gentle breeze blew across the roof. The leaf, completely devoid of friction, did not simply blow away. Without friction to anchor it to the atmosphere or the ground, the microscopic kinetic energy of the breeze accelerated it instantly. The leaf shot off the roof at Mach 2, creating a miniature sonic boom that cracked like a whip in the night air, disappearing into the dark sky before the eye could even track it.

 

Izuku closed his hand. The sonic boom echoed faintly off the neighboring buildings.

 

I am a sledgehammer, Izuku thought, his young mind solidifying a philosophy that would govern the rest of his life. And the world is made of glass.

 

If he swung, even a little, the glass would shatter. He couldn't afford to be angry. He couldn't afford to be careless. He couldn't afford the luxury of human error.

 

He remembered All Might’s debut video. The burning city, the screaming civilians, the roaring laugh of the Symbol of Peace as he carried a dozen people to safety on a single arm. Fear not! Why? Because I am here!

 

All Might saved people by being the strongest force in the room. He saved people by overpowering the disaster.

 

Izuku realized, with a heavy heart, that he could never be that kind of hero. He couldn't punch a villain to save a hostage, because his punch would obliterate the villain, the hostage, the building, and the city block. He couldn't catch a falling bridge, because the localized gravity manipulation would tear the earth's crust apart.

 

If he wanted to be a hero, he had to be a surgeon. He had to use tweezers to perform brain surgery, while holding a chainsaw.

 

He had to master his mind. He had to detach himself from the visceral, emotional reactions of fear, anger, and panic. He had to become a machine of pure logic and calculation, because if his emotions ever bled into his Quirk... there would be nothing left to save.

 

Izuku looked up at the stars, the vast, infinite expanse of the universe above him. He felt a strange kinship with the void.

 

"I won't break it," Izuku whispered to the empty roof, a solemn vow made by a god disguised as a boy. "I have the power to break everything. But I promise... I will spend my whole life making sure the glass stays in one piece."

 

He stood up, turning his back on the city, and walked downstairs to his room.

 

Tomorrow, he would start training. Not his body. His body was irrelevant.

 

He would train his mind. He would learn the limits of the world, so he could perfectly construct his own. He would become the quietest, safest, most contained entity in existence.

 

He was Izuku Midoriya. His Quirk was Infinity.

 

And he was going to save the world by choosing, every single second of every single day, not to destroy it.

 

To exist as Izuku Midoriya was to live in a state of perpetual, agonizing mindfulness.

 

For the average human being, movement was an autonomic process. You wanted to walk, so your brain fired electrical signals to your legs, and you simply walked. You wanted to open a door, so you grasped the handle, applied a generalized amount of torque, and pulled. You didn't calculate the tensile strength of the brass, the friction of the hinges, or the exact kinetic output of your bicep. You just lived.

 

Izuku could not afford that luxury.

 

He was fourteen years old now, a third-year student at Aldera Junior High, and his entire existence was a carefully choreographed performance of restraint. Every breath he took, every step he made, every word he spoke was filtered through a hyper-vigilant, continuously running mental algorithm.

 

He sat at his desk in the middle row of his classroom, a standard-issue, yellow No. 2 pencil held between his thumb and forefinger. He was writing notes on the whiteboard’s content—pre-quirk era world history—but his focus was entirely on the friction between the graphite and the paper. He applied precisely 0.4 Newtons of downward force. If his concentration slipped, if he allowed himself to become frustrated by the lesson or distracted by a bird outside the window, that 0.4 Newtons could instantaneously scale to infinity. The pencil would not break; instead, it would be driven with immeasurable force through the wooden desk, through the concrete floor of the school, tearing through the Earth’s crust and mantle, and potentially destabilizing the planet's core.

 

So, Izuku breathed in for a count of four, held it for a count of four, and exhaled for a count of four. He kept his face entirely blank, a mask of serene, almost clinical detachment.

 

This emotional quarantine was not born of apathy, but of profound, terrifying necessity. Joy could cause his power to flare. Sorrow could cause his power to isolate him. Anger—the most dangerous emotion of all—could cause his Quirk to erase whatever had offended him. He had spent the last ten years building a fortress of logic and mathematics around his soul. He viewed the world not as a teenager, but as a bomb disposal expert perpetually hovering over a ticking wire.

 

The classroom around him was loud, filled with the chaotic energy of adolescents boasting about their Quirks and their future plans. The homeroom teacher, a lanky man with a minor hair-lengthening Quirk, slammed a stack of career aptitude forms onto his podium.

 

"You're all third years now!" the teacher announced, his voice struggling to carry over the din. "It's time to start thinking seriously about your futures! I would hand out these career forms, but let's be honest..." He suddenly tossed the papers into the air, grinning. "You all want to be heroes, don't you?!"

 

The classroom erupted into cheers. Students activated their Quirks in a blatant violation of school rules—a boy stretched his neck to the ceiling, a girl generated a small cloud of sparkling dust, another student hardened his skin into rocky plates.

 

Izuku did not cheer. He didn't even look up. He carefully finished writing the date in his notebook, ensuring the curve of the '4' was perfectly symmetrical.

 

"Yes, yes, you all have wonderful Quirks!" the teacher laughed. "But remember, using them in school is against the rules! Now, let's see... Ah, Bakugo. You're aiming for U.A. High School, aren't you?"

 

The classroom instantly quieted. All eyes turned to the boy sitting in the row ahead of Izuku, slightly to the left.

 

Katsuki Bakugo was, by all conventional metrics, a prodigy. He was athletically gifted, academically brilliant, and possessed an incredibly versatile and powerful Explosion Quirk. In any other narrative, he would be the loud, brash center of attention, leaping onto his desk to declare his superiority over the "extras" in the room.

 

But not in this room. Not with the ghost sitting behind him.

 

Katsuki leaned back in his chair, his feet resting on his desk, but his posture was strangely stiff. He didn't turn around. He hadn't voluntarily made eye contact with Izuku Midoriya in a decade.

 

"Yeah," Katsuki grunted, his voice subdued, lacking its usual explosive bravado. "I aced the mock tests. I'm the only one from this crappy school who has a shot at the top."

 

It was a boast, but it felt hollow. It was recited out of habit, a script Katsuki felt compelled to read to maintain his own fragile ego. But he didn't trigger any explosions in his palms. His hands remained tightly stuffed into his pockets.

 

"Oh, right!" the teacher chimed in, oblivious to the heavy, oppressive tension that always settled over Katsuki whenever U.A. was mentioned. "Midoriya, you're also applying for U.A., aren't you?"

 

The silence that followed was absolute.

 

It was as if the air had been violently sucked out of the room. The cheering students froze. The boy with the stretched neck slowly reeled it back in. The girl with the sparkling dust let it clatter lifelessly to the floor.

 

Twenty pairs of eyes slowly, cautiously, slid toward the green-haired boy sitting perfectly still in the middle of the room.

 

Izuku finished writing a sentence. He placed the pencil down, ensuring it was parallel to the edge of the desk. He blinked slowly, his deep, emerald eyes looking up at the teacher. The teacher suddenly looked very pale, visibly swallowing a lump in his throat as if he had just realized he had poked a sleeping leviathan.

 

"Yes," Izuku said. His voice was soft, melodic, and entirely devoid of inflection. "I intend to take the U.A. entrance exam."

 

No one laughed.

 

In another world, a Quirkless boy declaring his intent to go to U.A. would have been met with uproarious, mocking laughter. Bakugo would have blown up his desk. The class would have ridiculed him.

 

But Aldera Junior High knew better.

 

They didn't know the exact nature of Izuku's Quirk. His official school registry simply listed his ability as 'Telekinesis (Anomalous)'. But children have a primal intuition that adults often suppress. They remembered the times a dodgeball had been thrown at Izuku’s head in gym class, only for the ball to simply stop in mid-air and disintegrate into a fine powder of rubber atoms. They remembered how, when a bully had tried to trip him in the hallway three years ago, the bully’s shoe had melted into slag upon entering a one-inch radius of Izuku’s leg.

 

They knew that Izuku Midoriya was not a student. He was a natural disaster holding its breath.

 

Katsuki Bakugo stared straight ahead at the chalkboard, a bead of sweat tracing its way down his temple. His jaw clenched so tight his teeth ached. If he goes to U.A., Katsuki thought, his heart hammering against his ribs, the whole damn country is going to find out what he is.

 

"W-well," the teacher stammered, shuffling his papers nervously, eager to move past the suffocating dread that had infected the room. "I'm sure... I'm sure you'll do your best, Midoriya. Moving on to the math syllabus..."

 

The bell rang a few hours later. The students filed out quickly, keeping a wide, respectful, and terrified distance from Izuku’s desk. Izuku packed his bag methodically. Notebook first, textbook second, pencil case third. He zipped the bag, stood up, and walked out of the classroom.

 

As he walked down the hallway, the seas parted. Students flattened themselves against the lockers to let him pass. Izuku kept his eyes forward, his face an impassive mask, but inside, a familiar, hollow ache thrummed in his chest.

 

Ten years, he thought. Ten years of silence.

 

He hated it. He hated the fear in their eyes. He hated that Katsuki, his childhood friend, looked at him like he was a monster waiting to snap. He understood it—logically, mathematically, their fear was completely justified. But the human part of his brain, the part that still loved All Might and wanted to make people smile, wept bitterly in the dark cage he had built for it.

 

Izuku left the school grounds and began his walk home. He took a longer, more secluded route. He preferred the quiet streets, away from the bustling crowds. Crowds meant variables. Variables meant a higher probability of an accident. Someone bumping into him, a car swerving onto the sidewalk, a villain attack—any sudden kinetic interaction required Izuku to consciously modulate his physical boundaries to prevent his Quirk from reflexively defending him with lethal force.

 

He walked with his hands in his pockets, his posture perfectly straight. His mind, as always, was running calculations.

 

U.A. High School Entrance Exam. Ten months away.

 

The physical portion of the exam was famously destructive—fighting giant robots in a faux city. The thought of it filled Izuku with a quiet, creeping dread. How could he possibly participate? If he punched a robot, the transfer of infinite kinetic energy would not stop at the robot. It would tear through the machine, through the ground, and likely crack the tectonic plate beneath Musutafu. If he used his spatial manipulation to crush the robot, the sudden vacuum created by the displaced matter would cause an implosion wave that would deafen every student within a five-mile radius.

 

He couldn't fight. He could only endure. He would have to find a way to neutralize the targets without applying active, escalating force. He had to be a surgeon.

 

His route took him under a long, concrete underpass. The shadows here were thick, the air cool and damp. Water dripped from a rusted grate above, echoing in the tunnel. Plink. Plink. Plink.

 

Izuku paused.

 

His hyper-analytical mind, finely tuned to the physics of his environment, registered an anomaly. The sound of the dripping water had changed. It was no longer striking the concrete pavement. It was striking something viscous. Something thick. Furthermore, the air pressure behind him had shifted. The scent of ozone, damp moss, and raw, fetid sewage flooded his olfactory sensors.

 

"A medium-sized invisibility cloak," a wet, gurgling voice echoed from the shadows behind him. "Perfect."

 

Izuku did not flinch. He did not gasp. He slowly turned around, his expression remaining perfectly blank, like a porcelain doll.

 

Rising from a manhole cover a few yards away was a nightmare. It was a massive, amorphous mass of dark green sludge, bubbling and shifting with a vile, semi-liquid consistency. Two enormous, bulbous eyes floated near the top of the mass, along with a jagged, chaotic mouth full of uneven, yellowed teeth. It was a Villain—a mutant-type, likely possessing extreme physical elasticity and immunity to standard blunt-force trauma.

 

"Don't worry, kid," the Sludge Villain rasped, his gelatinous body surging forward like a tidal wave of raw sewage. "It'll only hurt for about forty-five seconds. Then it'll all be over. I just need to borrow your body for a little while! I'm in a hurry!"

 

The villain lunged, a thick tendril of slime whipping through the air, aimed directly at Izuku’s face.

 

Most people would scream. Most people would throw their hands up in defense. Most people would turn and run.

 

Izuku simply sighed. It was a quiet, profoundly exhausted sound.

 

Variable encountered. Threat level: Low. Action required: Subjugation via Spatial Lockdown.

 

Izuku did not move his hands. He did not activate a flashy aura. He simply looked at the rushing wall of sludge and imposed his will upon the mathematics of the space between them.

 

He engaged his Quirk: "Concept: Infinity."

 

He selected a specific parameter: Zeno's Dichotomy Paradox.

 

The theory was simple: to reach a destination, one must first travel half the distance. Then, half the remaining distance. Then, half of that. Because space can be divided infinitely, motion is an illusion, as you must cross an infinite number of midpoints, which is mathematically impossible.

 

For the rest of the world, this was a philosophical thought experiment. For Izuku Midoriya, it was an executable command.

 

The Sludge Villain was three feet away. He was moving at roughly forty miles per hour. He anticipated the satisfying, wet smack of his body engulfing the teenager, the brief struggle, and the inevitable silence as he seized control of the boy's nervous system.

 

He crossed the first foot and a half in a fraction of a second.

 

Then, he crossed the next nine inches.

 

Then, four and a half inches.

 

Then, the world broke.

 

To the Sludge Villain, the teenager suddenly appeared to be standing at the end of a long, stretching tunnel. The villain pushed harder, accelerating his mass, determined to close the tiny, insignificant gap of two inches. But the harder he pushed, the further away Izuku seemed to get.

 

What the hell is this?! the villain thought, his eyes widening in confusion. A repulsion Quirk? A wind barrier?

 

He surged with all his might, pouring every ounce of his strength into crossing that final inch.

 

And that was his mistake. By continuing to apply forward momentum against an infinite spatial loop, the villain triggered the glitch.

 

The air around Izuku’s body—in a perfect, spherical radius of precisely twelve inches—began to distort. It looked as though the universe itself was struggling to render the graphics of reality. The air flickered with violent, silent bursts of static. Colors inverted momentarily—the green slime flashing a neon magenta, the gray concrete flashing blinding white.

 

The villain realized, with a sudden spike of primal terror, that he wasn't just failing to move forward. He was trapped.

 

The front half of his sludge body was caught in the infinite spatial fold. He tried to pull back. He tried to reverse his momentum and retreat down the manhole.

 

But he couldn't.

 

Because to move backward, he had to cross the infinite space he had already entered. He was locked in a localized pocket of non-Euclidean geometry. His body was suspended in mid-air, frozen like a fly in amber, stretching endlessly into a microscopic void that existed only a millimeter from Izuku’s skin.

 

"W-what... what did you do to me?!" the villain gurgled, his voice distorted, echoing as if it were being played through a broken radio underwater. The sound waves themselves were struggling to escape the infinite loop, compressing and stretching into bizarre, agonizing frequencies. "Let me go! I can't move! I can't feel my body!"

 

Izuku stood perfectly still inside the glitching sphere of static. He looked at the villain's floating eyeballs, which were darting around in blind panic.

 

"I cannot let you go," Izuku said, his voice carrying perfectly clear through the distortion, untouched by the paradox he had created. "If I drop the spatial loop while you are exerting forward momentum, the sudden release of your kinetic energy will cause you to accelerate past the speed of sound. You would splatter against the far wall of this tunnel, and the resulting shockwave would severely damage my auditory organs and the structural integrity of the bridge above us."

 

The villain's mind simply could not process the words. He was experiencing sensory deprivation and sensory overload simultaneously. His nerves were stretching across eternity. He felt as though he were falling down a bottomless pit, yet he was completely immobile.

 

"You're a monster!" the villain screamed, his consciousness beginning to fracture under the weight of the mathematical impossibility he was trapped inside. "Let me out! Let me OUT!"

 

Izuku closed his eyes. The villain's panic was irritating, but irrelevant. Izuku calculated the amount of time it would take for the villain to exhaust his stamina and cease all forward momentum. Once the villain stopped pushing, Izuku could safely collapse the space.

 

"Please stop struggling," Izuku instructed gently. "You are only extending the distance. If you relax, the paradox will resolve."

 

Before the villain could comprehend the instruction, a new variable entered the equation.

 

CLANG!

 

The manhole cover that the Sludge Villain had originally emerged from was suddenly, violently blown off its hinges. It flew upward, shattering against the concrete ceiling of the tunnel like a frisbee made of tissue paper.

 

A massive, imposing figure burst from the sewer, landing with a ground-shaking THUD that cracked the pavement.

 

"FEAR NOT, CITIZEN!" a voice boomed, echoing through the underpass with the force of a localized hurricane. "FOR I AM—!"

 

Izuku’s eyes snapped open.

 

Standing ten feet away was a mountain of a man, clad in a white t-shirt and cargo pants. He was impossibly muscular, with golden blond hair swept back into two towering bangs that defied gravity. His smile was blinding, radiating absolute confidence and overwhelming power.

 

It was All Might. The Symbol of Peace. The Number One Hero. Izuku’s idol since he was old enough to comprehend the concept of heroism.

 

All Might had drawn back his massive right arm, his muscles bulging, preparing to unleash a 'Texas Smash' that would obliterate the Sludge Villain with pure air pressure.

 

But as All Might looked down the tunnel, his heroic proclamation died in his throat. His fist froze mid-swing. The trademark, unshakeable smile faltered, replaced by an expression of profound, unadulterated bewilderment.

 

He had expected to find the Sludge Villain—whom he had been chasing for twenty minutes—assaulting a civilian. He had expected panic, screaming, and a desperate struggle for survival.

 

Instead, he found a fourteen-year-old boy in a black school uniform, standing perfectly still, his hands casually resting in his pockets. And floating just inches from the boy's face was the villain, immobilized in a sphere of flickering, aggressive static that looked like a tear in the fabric of the universe. The villain wasn't fighting. The villain was weeping, his liquid eyes wide with a cosmic terror that All Might had never seen on a human or mutant face before.

 

"What... in the name of..." All Might muttered, lowering his arm, the wind pressure dying down.

 

Izuku looked at All Might. For a brief, microscopic fraction of a second, the iron-clad cage around Izuku's emotions trembled. All Might. He's really here. But the training held. The cage snapped shut. He could not afford to be a fanboy. Not while maintaining an infinite loop.

 

"Hello, All Might," Izuku said politely, bowing his head precisely ten degrees, ensuring he did not alter the spatial coordinates of the barrier. "Are you looking for this individual?"

 

All Might blinked, stepping cautiously closer. He was a veteran of thousands of battles. He had fought Villains who could manipulate gravity, Villains who could warp time, Villains who could shatter cities. But the energy radiating from this boy... it wasn't power. Power had a signature. Power had a feeling of heat, or pressure, or wind.

 

This felt like staring over the edge of the Grand Canyon in pitch darkness. It was a profound, horrifying emptiness.

 

"Young man," All Might said, his voice dropping from its booming, theatrical register into something much more serious. "What... what are you doing to him?"

 

"He attempted to merge his biology with mine," Izuku explained clinically. "I initiated a localized spatial paradox to halt his momentum without causing kinetic blowback. He is currently trapped between the distances of one inch and zero inches. He is unharmed, but he is experiencing significant psychological distress due to the non-euclidean nature of his confinement."

 

All Might stared at the boy. The words made sense individually, but assembled together, spoken by a middle-schooler with dead, exhausted eyes, they were chilling.

 

All Might looked at the villain. "Hey! Sludge Villain! Surrender, or... well, or I'll punch you!"

 

"HELP ME!" the Sludge Villain wailed, his voice a distorted, agonizing screech of static. "PLEASE! MAKE HIM STOP! HE'S ERASING ME! I'LL GO TO TARTARUS! JUST GET ME AWAY FROM HIM!"

 

All Might looked back at Izuku. "Can you... can you let him go, young man? I have empty soda bottles in my pockets. I can contain him safely."

 

"I can," Izuku said. "But he must cease struggling. If I collapse the infinity while he is applying force, he will explode."

 

"Hey! You heard the boy!" All Might barked at the villain. "Stop moving! Relax your mass!"

 

The villain, desperate to escape the incomprehensible torment of eternity, immediately went slack. His liquid body stopped surging forward.

 

Izuku registered the drop in kinetic pressure. Variables aligned. Deactivating concept.

 

Izuku blinked.

 

The static vanished. The air snapped back to normal reality with a sharp pop, like a vacuum seal being broken. The spatial loop folded back into standard geometry.

 

With the distance suddenly restored to normal, the Sludge Villain’s body collapsed. Without his forward momentum, he simply splashed onto the concrete floor of the tunnel, a quivering, whimpering puddle of foul-smelling goo. He didn't even try to run. He just lay there, traumatized, muttering incoherent strings of numbers and pleading for his mother.

 

Izuku took a deliberate step back, giving All Might room to work.

 

All Might, shaking off his shock, quickly moved into action. He pulled two large, empty, two-liter soda bottles from his cargo pants. With terrifying speed and precision, he scooped the catatonic villain into the bottles, twisting the caps on tight.

 

"There," All Might said, holding the bottles up to the light. He turned to Izuku, putting his hands on his hips and forcing his trademark smile back onto his face. "Well! That was certainly unexpected! Thank you for your assistance, young civilian! But you really shouldn't use your Quirk without a license. Leave the dangerous Villains to the Pros, alright?"

 

It was a standard line. A PR response designed to reassure a civilian and politely reprimand a vigilante act.

 

Izuku didn't smile back. He didn't ask for an autograph. He just stared at All Might, his emerald eyes boring into the Number One Hero.

 

"I did not use my Quirk offensively, All Might," Izuku stated calmly. "I merely stood my ground. If I had left it to the Pros, he would have killed me before you arrived. And if I had actively fought back..." Izuku paused, looking at the concrete walls of the tunnel. "You would be standing in a crater right now."

 

The smile slipped from All Might’s face. Usually, kids boasted about their Quirks. My fire is hotter than Endeavor's! I can lift a car! But this boy wasn't boasting. He was stating a fact, with the grim, weary certainty of an oncologist diagnosing a terminal illness.

 

Suddenly, a violent spasm wracked All Might’s massive frame. He coughed, a thick glob of blood splattering against the back of his hand.

 

Damn it, All Might cursed internally. My time limit. I pushed too hard this morning.

 

Steam began to radiate from All Might's body, his massive muscles twitching. He needed to leave. He needed to jump away before the transformation happened.

 

"Well!" All Might said loudly, wiping the blood from his mouth and crouching low, preparing to jump. "I must be off! I have to deliver this evildoer to the police! Stay safe, young man!"

 

"Wait," Izuku said.

 

It wasn't a shout. It wasn't a plea. It was a single, quiet word, spoken with just a fraction of Izuku's unyielding will.

 

All Might felt his legs lock. He couldn't jump. It was as if the gravity around his boots had suddenly increased tenfold, anchoring him perfectly to the pavement. He looked back at the boy in shock.

 

"You are severely injured," Izuku said, his eyes scanning All Might's left side. "Your respiratory rate is shallow. You coughed up blood, indicating severe pulmonary trauma or internal hemorrhaging in the gastric tract. If you jump now, the sudden change in atmospheric pressure combined with the extreme G-force of your acceleration could rupture your remaining lung tissue."

 

All Might's jaw dropped. How... how does he know that?

 

"I can assist you to a secure location where you will not be observed by the public," Izuku offered, entirely unfazed by the Number One Hero's distress. "There is a high-rise building three blocks from here with an inaccessible roof. We can walk there. I will carry the bottles."

 

All Might looked at the boy. Then he looked at his own shaking hands. The steam was thickening. He couldn't hold the form for much longer. He was supposed to be the pillar, the untouchable god of heroism. Yet here he was, being calmly, clinically managed by a middle-schooler.

 

"...Alright," All Might grunted, his voice tight. "Lead the way."

 

 

 

Ten minutes later, the heavy metal door to the roof of the commercial high-rise clicked shut.

 

The roof was expansive, covered in gray gravel, dotted with humming HVAC units and ventilation shafts. The afternoon sun was beginning to dip, casting long, melancholic shadows across the cityscape.

 

As soon as the door closed, All Might’s massive body violently convulsed. A massive cloud of white steam erupted from his pores, obscuring him completely.

 

Izuku stood patiently near the edge of the roof, the two soda bottles resting on the gravel at his feet. He watched the steam clear.

 

When the fog dissipated, the towering, 6'2", five-hundred-pound mountain of muscle was gone. In his place stood a skeletal, emaciated man with sharp, sunken features, hollow blue eyes with dark sclera, and limbs so thin they looked like they might snap in a strong breeze. The white t-shirt hung off him like a tent.

 

Toshinori Yagi spat a fresh glob of blood onto the gravel, wiping his mouth with a bony wrist. He looked up, expecting the boy to be screaming, or running, or at least displaying profound shock.

 

Izuku's expression remained completely unchanged.

 

"A severe respiratory and gastric injury," Izuku deduced aloud, analyzing Toshinori's sunken left side. "Sustained approximately five years ago, based on the scar tissue formation and the corresponding timeline of your reduced public appearances and the shift in your patrol patterns. A villain fight you kept hidden from the media. Toxic Chainsaw?"

 

Toshinori let out a dry, raspy laugh, leaning heavily against the railing. "You're a sharp kid. No, not Toxic Chainsaw. A much... darker villain. I lost my stomach, and a good chunk of my respiratory system. I can only do hero work for about three hours a day now. The rest of the time, I look like this."

 

Toshinori waited for the pity. The disappointment.

 

Instead, Izuku simply nodded. "That is highly inefficient, but mathematically sound. You are burning a tremendous amount of cellular energy to artificially inflate your muscle mass and hold your organs together to project an image of invulnerability."

 

"Project an image..." Toshinori sighed, sliding down the railing until he was sitting on the gravel. "That's a cold way to put it. I'm a Symbol of Peace, kid. People need to believe that I'm invincible, or the crime rate skyrockets. Fear is the enemy."

 

"Fear is a biological necessity," Izuku countered, sitting down cross-legged a few feet away. "It prevents organisms from engaging in actions that lead to their destruction."

 

Toshinori looked at the boy. Really looked at him.

 

Toshinori had spent his life searching for a successor. He was looking for someone with a heroic heart. Someone who rushed in blindly to save others, even when they didn't have the power to do so. He had met thousands of kids who wanted to be heroes. They were all loud, passionate, and fiercely determined.

 

This boy... this boy was none of those things. He was quiet, clinical, and completely devoid of passion. He spoke like a supercomputer.

 

Yet, when Toshinori looked into those emerald eyes, he didn't see a machine. He saw an ocean of profound, crushing sorrow. He saw a child who had built a prison out of logic to contain something terrifying.

 

"What is your name, young man?" Toshinori asked gently.

 

"Midoriya Izuku."

 

"Midoriya. You said earlier... if you had actively fought that villain, I would be standing in a crater. And the way you trapped him... I've never seen a Quirk like that. What exactly is your power?"

 

Izuku looked down at his hands. For the first time, a flicker of hesitation crossed his stoic features.

 

"My Quirk is called Infinity," Izuku said softly.

 

"Infinity," Toshinori repeated. "You mean, you have a vast reserve of energy?"

 

"No," Izuku corrected. "I mean the mathematical concept. I do not have a physical limit. If I output energy, it does not stop. If I alter space, it folds forever. I am an anomaly. A glitch in the physics of reality."

 

Izuku slowly uncurled his hand. He looked at a small pebble resting on the gravel.

 

"When I was four," Izuku said, his voice dropping to a near whisper, the clinical detachment finally showing cracks, "I accidentally applied infinite kinetic energy to an action figure. It ceased to exist. I vaporized it. If I had applied that energy to the floor, I would have destroyed my apartment building. If I apply it to a person... they will be erased."

 

Toshinori’s breath caught in his throat. He stared at the boy in absolute horror. He understood power. His Quirk, One For All, was the culmination of eight generations of stockpiled strength. It was enough to level a city.

 

But it had a limit. Toshinori could measure his punches. He could hold back.

 

This boy was telling him that his baseline, his default state, was absolute destruction.

 

"You..." Toshinori swallowed hard. "You live with that? Every day?"

 

"Every second," Izuku replied, looking up, his eyes shining with unshed tears that he brutally forced back down. "If I get angry, I could kill everyone in my city. If I panic, I could shatter the earth. I have to be perfect, All Might. Every single day, I have to calculate every step, every word, every breath. Because if I make a mistake, people die."

 

The silence on the roof was deafening, save for the hum of the air conditioners.

 

Toshinori realized, with a sickening jolt, why the boy was so detached. It wasn't arrogance. It was a desperately constructed psychological dam. This fourteen-year-old boy was carrying a burden heavier than the entire hero society combined. Toshinori carried the weight of public expectation; Izuku Midoriya carried the weight of the planet's continued existence.

 

"And yet," Toshinori said, his voice thick with emotion, "you still want to go to U.A. You still want to be a hero. Why? With power like that, the safest thing for you to do would be to hide away. To do nothing."

 

"Because I want to save people," Izuku said, a raw, desperate honesty bleeding through his logical facade. "I watch you on the news. You save people with a smile. You make them feel safe. But everywhere I go, people look at me and they feel fear. My best friend won't speak to me. My teachers are terrified of me. I want... I want to prove to the world, and to myself, that I am not a monster. That I can use this... this error inside me, to protect the glass."

 

"The glass?"

 

"The world," Izuku explained. "It's made of glass. And I am a sledgehammer. I want to learn how to be a hero without breaking the glass."

 

Toshinori stared at the boy.

 

For months, Toshinori had been agonizing over his legacy. He needed to pass on One For All. He needed to find someone to bear the torch.

 

But looking at Izuku Midoriya, Toshinori realized something profound. This boy didn't need power. Giving this boy One For All would be like pouring a cup of water into a bottomless ocean. It would be meaningless.

 

What this boy needed was something much rarer, and much more difficult to provide.

 

This boy was a god. And gods, without humanity to tether them, become destroyers. Izuku had tethered himself through cold logic, but logic was brittle. It would eventually crack under the emotional strain of adolescence and isolation.

 

Izuku didn't need a Quirk. He needed a father figure. He needed a mentor. He needed someone strong enough, emotionally and physically, to stand next to him and not be afraid.

 

Toshinori slowly pushed himself up from the gravel. He walked over to Izuku and, despite the boy's immense, terrifying power, Toshinori did something no one had done to Izuku in ten years.

 

He placed a hand firmly, warmly, on the boy's shoulder.

 

Izuku flinched, his eyes widening in shock. He instinctively calculated the distance, the threat, the kinetic potential—but then he stopped. It was just a hand. A warm, heavy hand.

 

"Young Midoriya," Toshinori said softly, his hollow blue eyes filled with an immense, paternal compassion. "You are not a monster. You are a boy who has been given an impossible hand, and you are playing it with more bravery than any Pro Hero I have ever met."

 

Izuku’s lower lip trembled. The logical cage he had built shuddered violently under the sudden influx of genuine, unconditional empathy.

 

"You want to be a hero," Toshinori continued. "You want to learn how to save people without breaking the glass. I cannot teach you how to use your Quirk. I do not understand the math. I do not understand the physics."

 

Toshinori smiled—not the booming, theatrical smile of the Symbol of Peace, but the genuine, exhausted, beautiful smile of Toshinori Yagi.

 

"But I can teach you how to smile," Toshinori said. "I can teach you how to connect with the people you are trying to save. I can teach you martial arts, so you can fight without needing to use your power. You have spent your life isolating yourself to protect the world. Let me help you rejoin it."

 

Toshinori stepped back, looking the boy in the eye.

 

"I am not offering you my power, Midoriya. You have more than enough of your own. I am offering you my guidance. I am offering to be your anchor. Will you let me train you?"

 

Izuku Midoriya, the boy who held the concept of infinity in his chest, the boy who could erase cities with a thought, looked at the skeletal, broken man standing before him.

 

For the first time in a decade, the mental algorithm shut down. The calculations ceased.

 

Izuku broke.

 

He collapsed forward, burying his face into his hands, and he wept. He wept with the loud, ugly, desperate sobs of a child who had been holding his breath for ten years and was finally, finally allowed to exhale.

 

Toshinori didn't flinch. He simply knelt down, wrapping his thin arms around the shaking boy, holding him tight as the sun set over Musutafu.

 

The Symbol of Peace had not found a successor that day.

 

He had found a god. And he had decided to teach him how to be human.

 

The alarm clock on Izuku Midoriya’s bedside table did not ring.

 

It didn't have the chance. At precisely 4:59:59 AM, one millisecond before the digital hammer was programmed to strike the electronic chime, Izuku reached out and pressed the button, plunging the room back into the heavy, expectant silence of the pre-dawn morning.

 

He lay in bed for exactly one minute, staring at the ceiling. He was breathing in a measured, four-count rhythm. Inhale. Two. Three. Four. Hold. Two. Three. Four. Exhale. Two. Three. Four.

 

Today was the U.A. High School Entrance Exam. It was the culmination of his childhood dreams, the first step across the threshold into the world of professional heroes. Yet, as he threw off his covers and placed his bare feet on the hardwood floor, his heart rate remained a perfectly steady sixty beats per minute.

 

There was no nervous flutter in his chest. There was no adrenaline spike. Adrenaline was a chemical designed to trigger the fight-or-flight response, to bypass logic and engage primal instinct. Izuku had spent the last ten months meticulously training his body and mind to burn that instinct out of his system.

 

He walked to the bathroom and splashed cold water on his face. As he looked up into the mirror, the reflection that stared back was fundamentally different from the terrified, isolated boy who had cried on a rooftop ten months prior.

 

He was still lean, but the soft, unassuming lines of his adolescence had been forged into something resembling high-tensile steel. His shoulders were broader, his posture impeccably straight. Scars dotted his knuckles and forearms—not from his Quirk, but from the brutal, unyielding physical labor he had subjected himself to.

 

Toshinori Yagi had kept his promise. He had become Izuku’s anchor.

 

But Toshinori had not trained Izuku’s Quirk. They had both agreed, implicitly, that trying to "train" Infinity was like trying to train a hurricane. Instead, Toshinori had trained Izuku’s humanity.

 

For ten months, Izuku had spent every afternoon at Dagoba Municipal Beach. But he hadn't used his powers to clear the mountains of illegal trash. Toshinori had forbidden it. “If you use your power, you do not feel the weight of the world, Midoriya,” Toshinori had told him, standing amidst the rusted refrigerators and blown-out tires. “You need to feel the weight. You need to know what a hundred pounds feels like in your arms, so your mind respects it. You need to sweat. You need to bleed. You need to understand the physical limits of the human body, so you can appreciate the fragility of the people you will save.”

 

And so, Izuku had lifted. He had pulled trucks. He had carried appliances until his muscles tore and his hands blistered. He had learned martial arts, sparring with the emaciated but fiercely skilled former Number One Hero. He learned how to block, how to parry, how to shift his weight to neutralize momentum.

 

Most importantly, he learned that he could interact with the physical world without shattering it. He learned that pain was a grounding force. It reminded him that he was mortal, even if the entity resting in his chest was not.

 

Izuku dried his face, pulled on his Aldera Junior High uniform, and walked into the kitchen. His mother was already awake, frying eggs and bacon, her face a mask of poorly concealed anxiety.

 

"Morning, Izuku," Inko said, her voice trembling slightly as she set a plate down. "Did you sleep well?"

 

"I achieved REM sleep for the optimal four cycles, yes," Izuku replied gently, sitting at the table. He picked up his chopsticks, applying the exact necessary pressure to hold them. "Thank you for the meal, Mom."

 

Inko watched him eat. She loved her son more than life itself, but watching him was sometimes like watching a beautifully crafted android. She missed the smiles, the frantic muttering, the joyous fanboying. But she knew this was the price of his survival.

 

"Izuku," she said softly, reaching across the table to place her hand over his. "Please... be careful today."

 

Izuku stopped chewing. He looked at his mother's hand resting on his. He felt the warmth of her skin, the slight tremor in her fingers. He closed his eyes, accessing the emotional reservoir Toshinori had helped him begin to thaw.

 

He turned his hand over and gave hers a gentle, measured squeeze. He allowed the corners of his mouth to lift into a small, but entirely genuine, smile.

 

"I promise, Mom," he said softly. "I won't break the glass."

 

 

 

The gates of U.A. High School were monolithic. Towering pillars of metal and glass arched into the sky, forming a colossal 'H' that seemed to pierce the morning clouds. Hundreds of students were pouring through the entrance, a chaotic sea of varied uniforms, strange mutations, and nervous chatter.

 

Izuku walked among them, an island of perfect stillness in a raging river.

 

He analyzed the structural integrity of the archway, calculating the wind resistance of the glass panels. He cataloged the Quirks of the students passing him—a boy with engine pipes in his calves, a girl with pink skin and black sclera, a boy with a crow’s head. He processed their threat levels and adjusted his physical boundaries accordingly.

 

"Out of the way, Deku."

 

The voice was low, devoid of its usual explosive volume, but laced with a tense, vibrating anxiety.

 

Izuku paused. Walking past him, his hands shoved deep into his pockets, his shoulders hunched as if trying to make himself smaller, was Katsuki Bakugo.

 

Katsuki did not look at him. He stared fixedly at the pavement, accelerating his pace to put as much distance between them as possible. For the last ten months, Katsuki had treated Izuku like a live landmine. The fear had not faded; it had fermented into a deep, psychological avoidance.

 

"Good morning, Kacchan," Izuku said evenly, his voice barely carrying over the crowd. "Good luck today."

 

Katsuki visibly flinched. He didn't respond, merely breaking into a jog to disappear into the crowd. Izuku watched him go, feeling a familiar twinge of sorrow.

 

He resumed his walk toward the main auditorium. As he approached the steps, his hyper-vigilant senses caught a sudden shift in the auditory landscape. The sound of a shoe scuffing sharply against the pavement. The intake of a startled breath. The shifting of a center of gravity.

 

Three feet to his right, a girl with short, bobbed brown hair had tripped over her own feet. She was pitching forward, her hands flailing instinctively to brace for an impact with the unforgiving concrete stairs.

 

Time, for Izuku, did not slow down. He simply thought faster.

 

Variable encountered. Civilian falling. Distance: three feet. Velocity: increasing at 9.8 meters per second squared. Action required.

 

His instinct, the terrifying, slumbering god in his chest, immediately offered a solution: Target the girl. Apply Concept: Nullify Gravity.

 

Ten months ago, Izuku would have done it. He would have altered the laws of physics to suspend her in the air.

 

But Toshinori’s voice echoed in his mind. “You are human, Midoriya. Use your hands.”

 

Izuku did not engage his Quirk. Instead, he engaged his body.

 

His right foot pivoted, driving into the pavement with precise, calculated force. His leg muscles, hardened by pulling tons of garbage across the sand, fired instantly. He crossed the three feet in a fraction of a second, his movements a blur of martial efficiency.

 

Before the girl's face could meet the stairs, Izuku slid his right arm under her chest, bracing his stance. His left hand gently caught her flailing wrist. He absorbed her downward momentum entirely with his core, bending his knees to cushion the sudden stop.

 

The girl gasped, her eyes tightly shut. But the pain never came.

 

She opened her eyes, blinking rapidly. She was suspended an inch above the stairs, held securely in the arms of a boy with messy green hair and intense, incredibly focused emerald eyes.

 

"Are you unharmed?" Izuku asked, his voice calm, entirely devoid of exertion.

 

The girl stared at him, her face flushing a deep, sudden red. She scrambled to her feet, instinctively pressing her fingertips together. "Oh my gosh! I'm so sorry! I'm so clumsy, I just tripped over my own feet, and—wow, you move really fast! Thank you! That would have been a terrible omen, falling right before the exam!"

 

Izuku released her arm, stepping back to re-establish a safe physical boundary. He analyzed her. She was vibrating with nervous energy. Her cheeks were flushed. Her heart rate was elevated.

 

She is afraid of the exam, Izuku realized. She needs reassurance.

 

Izuku remembered what Toshinori had taught him. A hero’s job was not just to save the body, but to save the heart.

 

Izuku took a breath, letting his clinical mask slip just a fraction. He allowed a soft, reassuring smile to touch his lips. It felt entirely foreign, but it felt right.

 

"There are no such things as omens," Izuku said gently. "Only variables we can control, and those we cannot. You are safe now. That is a good start to the day. I wish you the best of luck."

 

The girl’s nervous rambling died down. The calm, unshakeable certainty in his voice acted like a soothing balm on her frayed nerves. She smiled back, a bright, sunny expression that momentarily made Izuku’s heart skip a beat.

 

"Thank you!" she beamed. "I'm Uraraka Ochaco! Let's both do our best!"

 

She waved and jogged up the stairs. Izuku watched her go. He looked down at his right arm. He had caught her. He had touched her. He had absorbed her kinetic energy, and he hadn't broken her.

 

He clenched his fist, a profound sense of accomplishment blooming in his chest. I am learning to be human.

 

 

 

The orientation in the auditorium was a sensory assault.

 

The Voice Hero, Present Mic, stood on the stage, projecting his voice at decibel levels that made Izuku’s highly tuned eardrums ache. The presentation outlined the practical exam: a massive, faux-city battleground where students would earn points by destroying robotic villains. There were 1-Pointers, 2-Pointers, and 3-Pointers.

 

"And then there's the Zero Pointer!" Present Mic screamed, striking a pose. "An obstacle! A massive gimmick that will rampage through the tight spaces! My advice? Run away from it! It's not worth the trouble, listeners!"

 

A tall, bespectacled boy with engine pipes in his legs—Izuku recognized him from the gate—stood up, robotically chopping his hand in the air. He began a loud, intense diatribe about U.A.'s prestige, the error in the pamphlet regarding the four robots, and even turned to scold Katsuki Bakugo for slouching in his seat.

 

Izuku ignored the interruption. His mind was already rendering a 3D model of the battlefield, calculating the parameters of the test.

 

Objective: Destroy robotic targets. Method: Unspecified. Constraint: Collateral damage must be mitigated.

 

The problem was fundamental. If Izuku punched a robot, he could not guarantee the kinetic transfer would stop at the machine's back plating. A traditional strike carried the risk of the energy piercing the robot, traveling as an invisible shockwave through the air, and obliterating the buildings behind it, or worse, another student.

 

He could not use raw force. He could not use standard spatial compression, as a large-scale vacuum collapse would shatter eardrums.

 

He needed a surgical tool. He needed to alter reality on a microscopic scale, localized entirely within the footprint of the targets.

 

By the time the students were loaded onto the buses and transported to Battle Center B, Izuku had finalized his algorithm.

 

The massive gates of the faux city loomed before them. The other students were stretching, hyperventilating, charging their Quirks. Uraraka was taking deep breaths, slapping her cheeks. The boy with the engines was jogging in place.

 

Izuku stood at the absolute back of the crowd. He closed his eyes.

 

Engage mental quarantine. Lock emotional receptors. Isolate analytical processing.

 

When his eyes opened, the soft, human warmth he had shown Uraraka was gone. The emerald irises were cold, calculating, and infinite. He was no longer a teenager taking a test. He was an executioner stepping up to a block.

 

"RIGHT, LET'S GO!" Present Mic's voice boomed from a speaker tower. "THERE ARE NO COUNTDOWNS IN REAL BATTLES! RUN, RUN, RUN!"

 

The crowd surged forward, a tidal wave of screaming teenagers rushing into the city. Explosions echoed almost immediately as Bakugo blasted his way down a main thoroughfare. Lasers flashed. Concrete crumbled.

 

Izuku did not run. He walked.

 

His pace was measured, perfectly even. He bypassed the main street, turning down a narrower alleyway to avoid the unpredictable variables of the other students.

 

He walked for precisely thirty seconds before he encountered his first targets.

 

Rolling around the corner of a building were three 2-Pointers. They were hulking, tread-bound machines with dual arm cannons, their red optical sensors swiveling mechanically. As soon as they registered Izuku, their targeting lasers locked onto his chest.

 

"TARGET ACQUIRED," a synthesized voice droned. "INITIATING TERMINATION PROTOCOL."

 

Izuku stopped. He analyzed the machines.

 

Mass: Approximately two tons each. Armor density: Standard reinforced steel. Distance: Twenty feet.

 

The robots raised their cannons.

 

Izuku did not raise his fists. He simply crouched down, placing his right index finger gently onto the asphalt beneath his feet.

 

He visualized a sphere, exactly one inch in diameter, located perfectly beneath the center of mass of the lead robot.

 

Target defined. Concept: Infinite Mass. Execution: Localized Gravity Well.

 

Izuku tapped the asphalt.

 

What happened next produced no explosion. There was no flash of light. There was no theatrical shockwave. In fact, it was the sheer, terrifying absence of sound that made the event so profoundly disturbing.

 

For exactly one-tenth of a second, the one-inch pocket of space beneath the robot gained infinite mass. It became, for all physical intents and purposes, a microscopic black hole.

 

The laws of physics screamed in agony, but they obeyed.

 

The lead 2-Pointer did not explode outward. It imploded inward. The two tons of reinforced steel, the treads, the arm cannons, the internal circuitry—all of it was subjected to an infinitely powerful, localized gravitational pull.

 

With a sickening, high-pitched shhhhhnk that sounded like reality tearing, the robot was instantly ripped from the three-dimensional plane and violently crushed into the singularity.

 

It took less than a blink of an eye.

 

Izuku immediately lifted his finger, severing the concept. The black hole evaporated.

 

Where a towering, two-ton machine had stood a second prior, there was now only a perfect, golf-ball-sized sphere of impossibly dense, compressed metal resting quietly on the asphalt. The air around it was perfectly still. Not a single pane of glass on the adjacent buildings had cracked. Not a speck of dust had been displaced outside the immediate target zone.

 

The other two 2-Pointers froze, their rudimentary AI completely failing to process the instantaneous deletion of their unit leader.

 

Izuku walked forward. He tapped the asphalt again.

 

Shhhhhnk.

 

Another robot vanished, replaced by a dense marble of scrap.

 

He took two more steps. Tap.

 

Shhhhhnk.

 

The alleyway was empty. Three small spheres of metal lay on the ground.

 

Izuku stood up, dusted off his trousers, and continued walking.

 

"Six points," he murmured softly. "Thirty-four required for a mathematically secure passing grade. Continuing patrol."

 

 

 

High above the battlefield, in a darkened, heavily fortified observation room, the teachers of U.A. High School sat before a massive bank of monitors.

 

Nezu, the principal—a creature resembling an amalgamation of a bear, a mouse, and a dog—sat in a high-backed leather chair, delicately sipping tea from a porcelain cup. To his left sat Snipe, the sharpshooting hero. To his right, the R-Rated Hero Midnight.

 

Standing in the back, shrouded in his capture weapon, was Shota Aizawa, the Erasure Hero. His bloodshot eyes were scanning the dozens of screens, looking for potential, looking for arrogance, looking for liabilities.

 

"We have a strong crop this year," Midnight purred, tapping a manicured nail on the console. "The explosion boy is incredibly aggressive, but his combat instincts are terrifyingly honed. And the girl with the gravity Quirk is showing excellent situational awareness."

 

"I like the kid with the engines," Snipe drawled, adjusting his cowboy hat. "Clean, efficient strikes. Good mobility."

 

Nezu nodded, taking a sip of his tea. "Indeed. The practical exam is designed to weed out those who cannot apply their abilities under pressure. It's a test of rapid decision-making and raw output."

 

Aizawa wasn't looking at Bakugo, or Uraraka, or Iida. His eyes were locked onto Screen 7, a feed displaying a narrow alleyway in Sector C.

 

"Hey," Aizawa grunted, his voice rasping like sandpaper. "Who is the kid on screen seven?"

 

Nezu raised an eyebrow, typing a command into the console. The main screen shifted to display the feed Aizawa was watching. A holographic profile popped up beside it.

 

"Midoriya Izuku," Nezu read aloud. "Aldera Junior High. Quirk Registry: Telekinesis (Anomalous). Written exam score: 100%. Flawless."

 

"Telekinesis?" Snipe asked, squinting at the screen. "That ain't telekinesis."

 

On the screen, Izuku was walking into a courtyard currently occupied by five 3-Pointers. He didn't break stride. As the robots charged him, he simply crouched, touched the ground, and stood back up.

 

One by one, the massive machines violently crumpled inward, letting out that terrifying, muffled shhhhhnk sound, leaving behind only tiny, hyper-dense spheres of metal.

 

The observation room fell dead silent.

 

"What... what did he just do?" Midnight whispered, sitting up straight, the playful demeanor entirely gone. "Did he crush them? I didn't see any energy emission. I didn't see any kinetic shockwaves."

 

Aizawa stepped closer to the screen, his eyes narrowing. As an underground hero, his entire life depended on analyzing and erasing Quirks. He knew how power worked. Emitters generated energy. Transformers altered their biology. Everything had a tell.

 

This boy had no tell. He wasn't sweating. He wasn't panting. He was walking through a warzone with the casual, disconnected demeanor of someone strolling through a park.

 

"Look at the environment," Aizawa said, his voice tense. "Look at the pavement where the robots were standing."

 

Nezu zoomed the camera in.

 

Beneath the tiny spheres of metal, the asphalt was completely undisturbed. There were no crater impacts. There were no scorch marks.

 

"Precision," Nezu murmured, his beady eyes widening in utter fascination. "Absolute, terrifying precision. He isn't just crushing them. He is collapsing their mass into a localized singularity. He's creating micro-black holes."

 

Snipe choked on a breath. "Black holes? Nezu, if he loses control of a black hole, he'll swallow the whole damn city!"

 

"But he isn't losing control," Nezu noted, leaning closer to the screen. "He's opening them for exactly the amount of time required to compress the target, and shutting them before they can affect the surrounding atmosphere. The mental calculation required to perform that once is staggering. He is doing it continuously."

 

Suddenly, the scoring algorithm on the right side of the main screen began to chime frantically. A red error box popped up over Izuku’s point total.

 

"What's wrong with the system?" Midnight asked, tapping the screen.

 

"The sensors inside the robots are designed to register kinetic impact, heat, or structural failure," Nezu explained, typing rapidly. "But Midoriya isn't destroying them conventionally. He is instantaneously compressing their mass to a sub-atomic level. The sensors aren't registering destruction. They're registering sudden, inexplicable non-existence. The algorithm can't calculate points for an object that simply drops off the physical plane."

 

Aizawa watched the boy on the screen. He felt a cold sweat prickle the back of his neck.

 

Telekinesis, Aizawa thought grimly. That's a cover-up. A government-level redaction. That boy is altering reality.

 

"Let's see how he handles the final test," Nezu said softly, a dark, manic gleam in his eye. He reached forward and flipped a heavy, red switch covered by a glass case. "Let's introduce the obstacle."

 

 

 

Izuku was standing in the center of a wide intersection. His internal counter read forty-five points. It was an adequate score. He had completed his objective without breaking a single pane of glass in the faux city.

 

He prepared to initiate his shutdown sequence and walk toward the exit.

 

Then, the ground beneath his feet heaved violently.

 

It wasn't a localized tremor. It was a massive, tectonic shift that sent shockwaves rippling through the asphalt. Buildings swayed, glass shattering and raining down like deadly hail.

 

A shadow fell over the intersection, blotting out the morning sun.

 

At the far end of the street, a monstrous hand, easily the size of a three-story building, slammed into the pavement. Concrete buckled and exploded under its weight.

 

Pulling itself from the depths of the facility was the Zero Pointer.

 

It was a leviathan of steel and circuitry, towering over the faux city like a mechanical god. Its massive treads crushed entire city blocks as it rolled forward. Its single, glowing red eye swept over the fleeing students, radiating an aura of apocalyptic destruction.

 

Panic erupted. Students screamed, abandoning their fights and sprinting desperately in the opposite direction.

 

"It's huge!"

 

"Run! Time's almost up!"

 

Izuku did not run. He stood in the center of the street, looking up at the colossal machine.

 

Threat level: Extreme. Mass: Unquantifiable. Potential for civilian casualties: High.

 

He calculated the distance. If the Zero Pointer continued its current trajectory, it would trample several students who had tripped in the panic.

 

He prepared to act. He would need a larger Micro-Infinity. Perhaps a ten-foot radius beneath its treads to swallow it into the earth.

 

"Ow! Help!"

 

The cry was weak, pained, but it pierced through the roar of the crumbling buildings.

 

Izuku’s head snapped to the right.

 

Fifty yards away, near the edge of the destruction path, Uraraka Ochaco was trapped. A massive slab of concrete from a ruined building had fallen, pinning her leg to the ground. She was struggling desperately to push it off, tears streaming down her face, but she was exhausted.

 

The Zero Pointer raised its massive foot, preparing to stomp down exactly where she was trapped.

 

Izuku’s eyes widened.

 

The mental algorithm shattered. The emotional quarantine he had maintained for ten months collapsed in an instant.

 

He didn't see a variable. He saw the girl who had smiled at him. He saw the girl who had thanked him. He saw a human life about to be extinguished, and a white-hot, terrifying surge of pure, unadulterated will flooded his veins.

 

He didn't run to her. There was no time.

 

Izuku looked up at the Zero Pointer. The sky-scraping machine was mid-step, thousands of tons of steel plummeting toward the earth.

 

Izuku raised his right hand, pointing his index and middle finger at the robot’s massive head. He pressed his thumb against his middle finger.

 

He did not use a black hole. A black hole of that size would drag Uraraka into the event horizon.

 

He needed to edit the machine out of existence, instantly, without a shockwave.

 

Izuku Midoriya stared at the mechanical titan, and he imposed an absolute, unbreakable mathematical law upon it.

 

Concept: Zero Spatial Distance.

 

Parameter: The Z-axis between the apex of the machine and the ground.

 

Execution.

 

Izuku snapped his fingers.

 

The sound was sharp, entirely mundane, lost in the roaring chaos of the battlefield.

 

But the universe heard it.

 

The Zero Pointer did not explode. It did not crumple.

 

It simply... ceased to be three-dimensional.

 

In the span of a single nanosecond, the infinite spatial distance that comprised the robot's height, width, and internal volume was violently, inexplicably reduced to zero.

 

To the terrified students watching, it looked as though the giant robot had been hit by a pause button, and then instantly compressed by an invisible, godly steamroller.

 

The colossal machine flattened. The thousands of tons of steel, wires, engines, and armor plating were crushed into a perfectly flat, two-dimensional plane upon the asphalt.

 

There was no debris. There was no explosion.

 

Where the towering monster had stood, there was now only a massive, perfectly detailed, 2D decal of a robot burned seamlessly into the pavement, completely flush with the ground.

 

The sudden displacement of millions of cubic feet of air created a massive, silent vacuum. Air rushed in from all sides to fill the void, creating a sudden, howling gale that swept through the street, blowing the dust away and whipping the students' hair wildly.

 

Then, absolute, terrifying silence fell over the faux city.

 

The students stood frozen, their mouths hanging open, their eyes wide with incomprehensible shock. They stared at the flat, 2D image of the robot on the street. It defied every law of physics, biology, and common sense.

 

Izuku lowered his hand. He took a deep, shuddering breath, violently forcing the emotional dam back into place. His hands were trembling. He had nearly lost control. He had nearly flattened the city block.

 

He ignored the stares of the terrified students. He walked quickly over to Uraraka.

 

She was staring at him, her face pale, her jaw trembling.

 

Izuku didn't speak. He knelt beside her, bracing his hands under the massive concrete slab pinning her leg. He didn't use his Quirk. He used the muscles Toshinori had forced him to build.

 

With a grunt of physical exertion, Izuku heaved the slab up, throwing it to the side.

 

"Are you broken?" Izuku asked, his voice returning to its clinical, measured cadence, though a slight tremor betrayed his lingering adrenaline.

 

"I... I..." Uraraka stammered, looking from Izuku, to the 2D robot on the street, and back to Izuku. "What... what are you?"

 

"THE EXAM IS OVER!" Present Mic’s voice echoed, breaking the spell.

 

Izuku stood up, offering his hand to Uraraka. She looked at his hand for a long moment, terrified. But then, she remembered his gentle smile at the gate. She remembered that he had saved her. She took his hand, and he pulled her up.

 

 

 

In the observation room, the silence was suffocating.

 

None of the teachers were speaking. None of them were moving.

 

Nezu’s porcelain teacup lay shattered on the floor, the hot tea seeping into the expensive carpet. The principal’s paws were shaking.

 

Snipe had pulled his gun halfway out of its holster, a purely instinctual reaction to witnessing an act of godhood.

 

Midnight was gripping the console so tightly her knuckles were white.

 

Aizawa stood perfectly still, his eyes wide, his Erasure Quirk flaring uselessly. He had seen it. He had watched the boy snap his fingers and turn a million-ton machine into a shadow.

 

"He... he deleted the Z-axis," Nezu whispered, his voice trembling with a mixture of absolute awe and primal terror. "He didn't destroy it. He altered the geometric reality of its existence."

 

Suddenly, the main scoring monitor let out a harsh, screeching tone.

 

The entire system, attempting to calculate the point value of a target that had been mathematically compressed into a two-dimensional state, suffered a catastrophic logic failure.

 

The screens flickered wildly, lines of code racing down the monitors in a desperate attempt to resolve the paradox.

 

Then, the screens went completely blue.

 

A single line of text appeared in stark, white lettering.

 

Examinee 7111: Midoriya Izuku.

Villain Points: Error ∞

Rescue Points: Error ∞

SYSTEM FATAL EXCEPTION.

 

Nezu stared at the screen. He slowly reached down and pressed the intercom button.

 

"Aizawa," Nezu said softly. "I want that boy's file. All of it. And call the government. We need to know exactly what we just let into our school."
