What If Deku's Quirk Was Airbending... and It Was Broken

 

 

 

 

The world, as Izuku Midoriya would later come to understand, was entirely held together by things that could not be seen.

 

Gravity anchored the planets, electromagnetic fields shielded the earth from the sun's wrath, and the delicate, invisible soup of nitrogen, oxygen, and argon cradled all biological life. Most people walked through this invisible sea without a second thought. They breathed it in, they breathed it out, and they complained when it was too hot or too cold. To the average person, the air was just empty space waiting to be filled by something more important.

 

For Izuku Midoriya, the air was not empty space. It was a canvas, a weapon, a shield, and a living, breathing extension of his own nervous system.

 

But before he understood the atomic weight of oxygen, before he could calculate the exact barometric pressure required to shatter steel, and long before the world would come to look upon him with a mixture of absolute awe and deeply rooted terror, he was just a four-year-old boy sitting in a sterile pediatrician's office, waiting for a miracle.

 

 The Awakening

 

Dr. Tsubasa’s clinic smelled sharply of rubbing alcohol and old paper. The walls were plastered with faded posters of popular Pro Heroes—Endeavor engulfed in flames, Best Jeanist posing stoically, and, of course, a massive, grinning All Might.

 

Izuku sat on the crinkly paper of the examination table, his short legs kicking back and forth. His mother, Inko, sat in the chair beside him, her hands nervously wringing the fabric of her skirt.

 

"Now then, Mrs. Midoriya," Dr. Tsubasa said, adjusting his round spectacles as he reviewed the x-rays on his glowing clipboard. "We've completed the preliminary scans. The genetic markers, the toe-joint test... everything."

 

Izuku stopped kicking. He leaned forward, his massive green eyes sparkling with the intensity of a thousand supernovas. This is it, he thought, his tiny heart hammering against his ribs. This is when I find out how I'm going to save people. He had spent the last year watching Katsuki Bakugo show off his explosive sweat, watching other kids stretch their fingers or levitate blocks. Izuku was late to the party, but he didn't care. He just wanted his invitation.

 

Dr. Tsubasa sighed, a heavy, tired sound that seemed to suck the joy out of the room. He set the clipboard down. "I'll be blunt. The boy possesses the extra joint in his pinky toe. Usually, this indicates that the evolutionary leap hasn't occurred. It is the universal biological marker for a Quirkless individual."

 

The word hung in the air. Quirkless.

 

It felt as though all the oxygen had suddenly been vacuumed from the small examination room. Inko gasped, her hands flying to her mouth, tears instantly pricking the corners of her eyes. Izuku just stared, his All Might action figure slipping from his small, trembling fingers to clatter against the linoleum floor.

 

"Q-Quirkless?" Inko stammered, her voice cracking. "But... but my husband breathes fire! And I can pull small objects! Surely there's a mistake, doctor. Surely..."

 

"Biology is rarely fair, Mrs. Midoriya," the doctor said, his tone sympathetic but clinical. "Sometimes the genetic lottery just doesn't pan out. I suggest you help him find a more realistic dream. He'll live a perfectly normal life, but hero work? It's out of the question."

 

Izuku didn't cry. Not at first.

 

Instead, a strange, overwhelming pressure began to build behind his eyes, radiating down his throat and into his chest. It felt like a physical weight, a suffocating, unbearable tightness. The injustice of it all, the sheer, absolute finality of the doctor’s words, began to curdle into a profound, child-like despair. The tears finally came, hot and fast, streaming down his freckled cheeks.

 

He squeezed his eyes shut, his tiny fists clenching so hard his knuckles turned white. His breathing hitched. He took a sharp, jagged inhale, sobbing openly now. The pressure in his chest was mounting, expanding, burning. The air in the room suddenly felt thick, heavy, like the atmosphere before a torrential thunderstorm.

 

"Izuku, sweetie..." Inko reached out, her heart breaking for her son.

 

But Izuku couldn't hear her. The pressure in his chest reached a critical mass. His nose tickled. His breath hitched one final time.

 

Izuku Midoriya sneezed.

 

It wasn’t a normal sneeze. It was a violent, concussive expulsion of force that defied all laws of pediatric biology.

 

BOOM.

 

The sound was akin to a cannon firing indoors. A shockwave of hyper-compressed air erupted from the four-year-old’s face. It tore through the clinic with the force of a localized hurricane. The medical charts flew into the air, instantly shredded into confetti. The examination table buckled. Dr. Tsubasa was thrown backward, his chair spinning wildly until he slammed into the wall.

 

But the force didn't stop there. The blast of air hit the ceiling of the clinic. The plaster cracked, the wooden support beams splintered with a deafening CRACK, and, in an instant, a ten-by-ten foot section of the clinic's roof was simply blown clean off its foundation, launched into the afternoon sky like a frisbee.

 

Silence descended upon the room, save for the gentle fluttering of shredded paper and the distant sound of car alarms going off in the street.

 

Sunlight poured into the examination room through the newly formed, jagged skylight. A gentle breeze wafted down, rustling Inko's hair. She sat frozen, her hand still reaching out, her jaw unhinged in absolute shock. Dr. Tsubasa lay against the far wall, his glasses askew, staring up at the blue sky visible through his ceiling.

 

Izuku blinked, his tears instantly drying up. He looked at his hands. He looked at the hole in the roof. He looked at the doctor.

 

Dr. Tsubasa slowly pushed himself up, wiping a piece of drywall from his shoulder. He looked at the x-rays scattered on the floor, then up at the four-year-old boy sitting beneath a pillar of sunlight.

 

"Well," the doctor squeaked, his clinical composure entirely shattered. "It appears... I may need to run those tests again."

 

When the updated registry forms were filed three weeks later, the extra toe-joint anomaly was officially classified as a rare, localized mutation that had no bearing on his Quirk factor.

 

The Quirk was officially registered under the name: Aerokinesis.

 

 The Science of "Broken"

 

Most children who received elemental Quirks treated them like toys. A child with a fire Quirk would roast marshmallows; a child with a water Quirk would splash in puddles.

 

Izuku Midoriya was not most children.

 

Endowed with a genius-level intellect and an almost obsessive need to analyze the mechanics of the world around him, Izuku didn't just want to blow wind around. He wanted to understand what he was controlling.

 

By the time he was eight years old, his bedroom looked less like a child's sanctuary and more like a university physics laboratory. The All Might posters were still there, of course, but they were now surrounded by corkboards pinned with meteorological charts, barometric pressure graphs, and detailed chemical breakdowns of the Earth's atmosphere. His famous "Hero Analysis for the Future" notebooks had evolved. They were no longer just observations of heroes’ fighting styles; they were advanced treatises on applied physics.

 

Izuku quickly realized that "controlling the wind" was an insultingly simplistic way to describe his Quirk. He didn't control wind. Wind was just the side effect of high-pressure air rushing to fill a low-pressure zone.

 

No, his Quirk was Atmospheric Manipulation. He had absolute, telekinetic dominion over the gaseous state of matter within a certain radius of his body.

 

Sitting on his bedroom floor on a rainy Tuesday evening, an eight-year-old Izuku held his hand out toward a heavy, hardcover dictionary resting on his desk. He didn't blow a gust of wind at it to knock it off. That was inefficient. Instead, he simply increased the air density underneath the book.

 

To his eyes—or rather, to his senses, as his Quirk gave him a unique, omnidirectional spatial awareness of the air around him—he gathered the scattered air molecules and packed them tightly together beneath the leather cover.

 

The dictionary trembled, then slowly hovered an inch off the desk, resting on an invisible pillar of solid, compressed air. Izuku smiled, a small, triumphant grin.

 

He opened his notebook, labeling the page: Experiment 42 - Density and Support.

 

Notes: By compressing the ambient nitrogen and oxygen molecules, I can create semi-solid constructs. The denser the compression, the harder the construct. Theoretically, if I compress the air tight enough, it could rival the tensile strength of concrete.

 

He dropped his hand, and the dictionary slammed back onto the desk.

 

But Izuku’s experiments went far beyond just lifting things. He began to explore the terrifying implications of his power.

 

If he could control the movement of air molecules, he could control friction. And if he could control friction, he could control temperature.

 

One winter, when the heating in their apartment broke, Inko came into his room with extra blankets, only to find it feeling like a warm summer day inside. Izuku sat in the center of the room, subconsciously agitating the air molecules around him, causing them to vibrate rapidly, generating ambient heat.

 

Experiment 88 - Thermodynamics.

Notes: Accelerating molecular vibration increases temperature. Decelerating it lowers temperature. I am not just a wind generator. I am an absolute climate control system.

 

Then came sound. Sound was nothing more than mechanical waves traveling through a medium—specifically, air. When Izuku realized this, he unlocked a new level of stealth. If he wanted to stay up late watching hero debuts on his computer without his mother hearing, he didn't turn down the volume. He simply created a localized vacuum bubble—a sphere of absolute emptiness—around his door. Without air to carry the vibrations, the sound simply ceased to exist beyond the threshold of his room.

 

But it was the concept of the vacuum that truly sobered Izuku.

 

When he was ten, he found a dying, aggressive hornet in his room. Instead of swatting it, he tested his control. He isolated the air immediately surrounding the insect and pulled it away.

 

The hornet dropped out of the sky instantly, suffocating in a localized void.

 

Izuku stared at the dead insect for a long time. The weight of what he had done, of how easily he had done it, settled heavily onto his young shoulders.

 

If I can do this to a bug, he thought, his stomach twisting into a cold knot, I can do it to a person.

 

Most Quirks had built-in limitations. Endeavor could overheat. Kamui Woods could catch fire. Best Jeanist needed clothing.

 

Izuku’s Quirk had no such restrictions. As long as he was on planet Earth, he possessed an infinite, inexhaustible supply of ammunition. He didn't need to generate the air; he just commanded it. He could rip the oxygen from a villain's lungs with a thought. He could compress the air in someone's ear canals and burst their eardrums. He could create a vacuum blade sharp enough to slice through a skyscraper.

 

His Quirk wasn't just strong. It was, from a biological and physics standpoint, entirely broken.

 

It was that realization that forged Izuku’s ultimate resolve. If he had the power of a god of destruction, he had to have the discipline of a saint. He could never lose his temper. He could never act out of malice. He had to be perfect, or he risked becoming a monster.

 

He would be a hero. A hero who saved everyone, a hero who restrained his terrifying potential behind a wall of absolute self-control.

 

 The Bakugo Dynamic

 

Katsuki Bakugo was a prodigy. He was born with a flashy, powerful Quirk, a sharp mind, and an ego the size of Musutafu. From the moment he manifested his Explosion Quirk, the adults in his life had crowned him the future number one hero.

 

In another universe, this relentless praise might have molded Katsuki into a vicious bully, one who preyed on the weak—specifically, a Quirkless Izuku Midoriya—to validate his own superiority.

 

But in this universe, Katsuki Bakugo’s superiority complex hit a brick wall of atmospheric pressure at the age of seven.

 

It happened at the local park. Katsuki and his lackeys were cornering a younger boy whose only crime had been accidentally bumping into Katsuki on the swings.

 

"Watch where you're going, extra!" Katsuki snarled, small, crackling explosions popping in the palms of his hands. The smell of burnt caramel filled the air. The younger boy whimpered, backing up against an oak tree.

 

"Leave him alone, Kacchan."

 

Katsuki paused, turning around. Izuku stood a few paces away. He wasn't trembling. He wasn't crying. His green eyes were calm, calculating, and intensely focused on Katsuki's hands.

 

"Deku," Katsuki scoffed, using the derogatory nickname he had coined years ago. "Mind your own business. Or do you want me to fry you, too?"

 

"You're being irrational, Kacchan," Izuku said, his voice terrifyingly steady for a seven-year-old. "He just bumped into you. There's no need for violence."

 

Katsuki’s pride flared hotter than his explosions. Being talked down to by the weird nerd who spent all day mumbling over notebooks was unacceptable. "Shut up! I'll show you who's irrational!"

 

Katsuki lunged. He reared his right hand back, sweat secreting rapidly from his nitroglycerin-like glands. He aimed a point-blank blast right at Izuku’s chest, intending to singe his shirt and teach him a lesson in the natural hierarchy of the world.

 

"Die!" Katsuki yelled, swinging his palm forward and igniting the sweat.

 

But the explosion never happened.

 

There was no deafening boom. There was no flash of blinding light. There was only a pathetic, wet hiss.

 

Katsuki blinked, stumbling forward as his momentum carried him. He looked down at his palm. It was smoking slightly, but the spark had died the exact millisecond it had ignited.

 

"What the...?" Katsuki muttered, staring at his hand in disbelief. He tried again with his left hand. Hiss. Nothing. Not even a spark.

 

"Combustion requires three things, Kacchan," Izuku said quietly, not having moved an inch. "Fuel, heat, and oxygen."

 

Katsuki looked up, his crimson eyes wide with confusion.

 

Izuku lifted his hand, his fingers slightly curled. "You have the fuel—your sweat. You have the heat—your ignition spark. But if I pull all the oxygen within a one-foot radius away from your hands... you have no fire."

 

Katsuki’s breath hitched. He looked at his hands, then at Izuku. The realization hit him like a physical blow. His Quirk—his invincible, ultimate, hero-making Quirk—was entirely useless against this boy. Izuku could literally turn him off.

 

Rage, hot and blinding, overtook Katsuki. "You bastard! Stop messing with my Quirk!" He abandoned his explosions, balling his hands into regular fists, and charged Izuku, aiming a right hook at the boy's jaw.

 

Izuku didn't flinch. He didn't even raise his arms to block. He simply shifted his stance and exhaled.

 

A wall of solid, highly pressurized air slammed into Katsuki’s chest. It wasn't a gust of wind; it felt like being hit by a mattress moving at fifty miles per hour. Katsuki was swept off his feet, thrown backward through the air, and deposited squarely on his backside in the sandbox, ten feet away.

 

The two lackeys staring in shock instantly bolted, abandoning their leader.

 

Izuku lowered his hand, his expression entirely devoid of arrogance or malice. It was just a statement of fact. He walked over to the younger boy, helped him up, and patted his shoulder. "You should head home," Izuku said softly. The boy nodded frantically and ran off.

 

Izuku turned his gaze back to Katsuki, who was sitting in the sand, trembling with a mixture of humiliation, fury, and a brand-new emotion he had never felt before: fear.

 

"I don't want to fight you, Kacchan," Izuku said, his voice carrying clearly over the empty playground. "Your Quirk is amazing. You're going to be a great hero. But if you try to hurt people for no reason, I will stop you."

 

From that day forward, the dynamic between them fundamentally shifted.

 

The bullying ceased entirely. Katsuki Bakugo never picked on another kid in Izuku’s presence again. How could he? How could he parade around acting like a god when the quiet kid in the back of the class held his leash?

 

But Katsuki didn't give up. The humiliation didn't break him; it forged him. If his explosions could be negated, he had to become faster than Izuku’s reaction time. If his blasts could be snuffed out, he had to learn to fight hand-to-hand. Katsuki threw himself into brutal physical training, mastering martial arts, endurance, and tactical combat.

 

Their relationship became a silent, intense rivalry. Katsuki glared at Izuku from across the classroom, not with the sneer of a bully, but with the predatory focus of a rival who was desperately trying to climb a mountain that seemed infinitely high. Izuku, in turn, respected Katsuki’s drive, quietly cheering on the explosive boy's relentless pursuit of perfection.

 

They weren't friends. But they were equals bound by a mutual, unspoken understanding: one was the unstoppable force, and the other was the immovable object.

 

 The Art of the Wind

 

As Izuku grew older, his control over his Quirk deepened, but so did his anxiety about accidentally hurting someone. His power was invisible; a single miscalculation in pressure could crush a classmate's windpipe instead of just pushing them back.

 

He realized that raw analytical intelligence wasn't enough to govern his power. He needed a physical outlet, a philosophy of movement that married his body to the element he controlled. He needed martial arts.

 

But standard karate or boxing was too rigid, too linear. They relied on stopping power and brute force. Izuku didn't need to punch hard; his Quirk did the heavy lifting. He needed a style that focused on evasion, redirection, and fluidity.

 

After months of research, studying ancient texts and watching old videos on the internet, Izuku found it: Baguazhang.

 

An ancient Chinese martial art, Baguazhang translated to "Eight Trigram Palms." It was the martial art upon which fictional airbenders in pre-Quirk era cartoons were based. It was characterized by circle walking, fluid footwork, and yielding to an opponent's force rather than meeting it head-on. It taught that the practitioner should move like a leaf caught in a gale—untouchable, drifting, always in motion, striking from unexpected angles.

 

Izuku adopted Dagobah Municipal Beach as his dojo.

 

The beach was a notorious illegal dumping ground, piled high with rusted refrigerators, broken trucks, and heaps of scrap metal. It was the perfect place to train away from prying eyes.

 

At the age of twelve, Izuku began his regimen. At sunrise, before school, he would stand among the towering mountains of trash. He started with the basics of circle walking. He learned to glide his feet across the sand without disturbing it, shifting his weight seamlessly.

 

As he moved, he extended his senses outward, feeling the microscopic currents of air flowing between the jagged edges of rusted metal. He synced his breathing to the natural ebb and flow of the ocean breeze.

 

Then, he began to integrate his Quirk.

 

He practiced moving gracefully among the junk, spinning and weaving. As he threw a palm strike into the empty air, a localized cyclone would burst from his hand, tearing the door off a broken microwave fifty feet away. As he pivoted on his heel, he would conjure a cushion of compressed air beneath his feet, allowing him to glide frictionless across the sand, moving at speeds that blurred the human eye.

 

He didn't just fight with the wind; he became it.

 

To increase his precision, he set up rigorous trials. He would stack twenty empty soda cans on a rusted steel beam. Standing thirty yards away, he would execute a complex Baguazhang form, sending out microscopic, razor-thin blades of high-pressure air.

 

Swish. Swish. Swish.

 

The air blades would slice cleanly through the exact center of each aluminum can, leaving the top half to fall perfectly onto the bottom half without knocking the stack over.

 

If he could slice aluminum from thirty yards without disturbing the balance, he could neutralize a villain without inflicting lethal damage.

 

By his fourteenth birthday, Izuku Midoriya was a master of his own element. His physique was lean, compact, and packed with the wiry muscle of a gymnast. His reflexes were preternatural, aided by his ability to feel changes in air pressure when an object (or a fist) moved toward him. He didn't even need to look to dodge; the displaced air warned him of incoming attacks before they arrived.

 

He was peaceful. He was polite. He still mumbled into his notebooks and blushed when girls spoke to him.

 

But beneath that mild-mannered exterior lay a sleeping hurricane.

 

 The Sludge Villain Incident

 

Aldera Junior High was as loud and chaotic as usual. It was the end of the school day, and the homeroom teacher had just thrown a stack of career aptitude papers into the air.

 

"You're all third years now! It's time to start thinking seriously about your futures!" the teacher yelled over the cheers of the students, who were showing off their Quirks. "But who am I kidding? You all want to be heroes!"

 

The classroom erupted. Students elongated their necks, fired water from their fingertips, and manifested glowing energy.

 

Izuku sat quietly at his desk in the back row, calmly writing in his notebook (Volume 13). He didn't join the cheering. He simply kept his head down, calculating the terminal velocity of Mt. Lady's giant form.

 

"Hey, teach, don't lump me in with these rejects!" a loud, arrogant voice cut through the noise.

 

Katsuki Bakugo leaned back in his chair, his feet propped up on his desk, a feral grin on his face. "They'll be lucky to end up as sidekicks to some busted D-lister. I'm going to UA High School. I aced the mock test, and I'm going to surpass All Might himself!"

 

The class murmured in awe. UA High was the most prestigious hero academy in the nation, boasting a microscopic acceptance rate.

 

"Ah, yes, Bakugo," the teacher said, looking down at his clipboard. "You are aiming for UA. But... oh, Midoriya, you're also applying for UA, aren't you?"

 

The classroom fell dead silent. Every head turned to look at the green-haired boy in the back.

 

In another life, this would be the moment the class erupted into mocking laughter, ridiculing the Quirkless boy for having an impossible dream.

 

In this life, nobody laughed.

 

They all remembered the time in first year when a senior student had tried to extort lunch money from Izuku. The senior had possessed a formidable hardening Quirk. Izuku hadn't even looked up from his book. He had simply snapped his fingers, creating a micro-vacuum in the senior’s inner ear, completely destroying his equilibrium. The bully had spent the next three hours vomiting into a trash can, entirely unable to stand up, while Izuku politely finished his bento box.

 

The students of Aldera Junior High didn't mock Izuku Midoriya. They were mildly terrified of him.

 

Katsuki didn't blow up Izuku’s desk. He didn't scream at him. Instead, the explosive blonde slowly turned his head, his crimson eyes locking onto Izuku’s green ones. Katsuki’s jaw clenched, a vein pulsing in his forehead.

 

"You better not hold back at the exams, Deku," Katsuki growled, his voice low and dangerous. "I'm going to crush you and prove I'm the best. No tricks this time."

 

Izuku looked up from his notebook, his expression serene. "I'll do my best, Kacchan. Good luck to you, too."

 

Katsuki scoffed, kicking his desk and storming out of the classroom as the bell rang.

 

Izuku packed his bag methodically. He took his time walking home, opting for the route that took him under a quiet overpass. He enjoyed the silence. The city was always so noisy, a cacophony of soundwaves that his Quirk constantly picked up on. Here, in the damp shade of the tunnel, the air was still and quiet.

 

He was reviewing his notes on Kamui Woods' tensile strength when his spatial awareness spiked.

 

The air pressure behind him had shifted dramatically. A massive, amorphous volume of matter had just displaced the oxygen near the manhole cover.

 

Izuku stopped walking. He didn't turn around.

 

"A medium-sized meat suit..." a wet, gurgling voice echoed through the tunnel. "Perfect. I need a place to hide. Don't worry, kid. It'll only hurt for about forty-five seconds."

 

A massive, sentient wave of putrid, dark green sludge erupted from the sewers, lunging toward Izuku’s back. The Sludge Villain intended to force himself down the boy's throat, hijacking his body to escape the pro hero pursuing him.

 

The sludge crashed down over Izuku, entirely engulfing his small frame.

 

The villain laughed, a sickening, bubbly sound. "Thanks for the body, kid! You're a real lifesaver!" He began to force his liquid form toward Izuku’s mouth and nose.

 

Inside the dark, suffocating mass of slime, Izuku didn't panic. His heart rate remained a steady sixty beats per minute. He closed his eyes and visualized the atmospheric pressure around him.

 

Sludge is a non-Newtonian fluid, Izuku thought calmly. It behaves like a liquid under low stress, but under high pressure, it acts like a solid. Let's test that.

 

Izuku took a shallow breath, grounding his stance.

 

Baguazhang Form 2: Expanding Lotus.

 

Izuku pushed his aura outward. He violently gathered the ambient air molecules from outside the villain's body, drawing them inward through the sludge, and rapidly compressed them into a perfect, spherical dome radiating outward from his skin.

 

He didn't just push the villain away; he weaponized the barometric pressure.

 

FWOOSH.

 

A dome of solid, hyper-compressed air expanded from Izuku with explosive force. The sudden, immense pressure hit the sludge from the inside.

 

"What the—?!" the villain gurgled, his eye stalks widening in absolute terror as he felt his liquid body being stretched to its absolute atomic limit. "What is this pressure?! I'm—I'm gonna—!"

 

POP.

 

The sound was exactly like a giant water balloon exploding.

 

Unable to contain the rapidly expanding atmospheric pressure, the Sludge Villain was literally blown apart from the inside out. Viscous green slime splattered violently against the walls, ceiling, and floor of the tunnel in a three-hundred-and-sixty-degree radius.

 

The dome of air dissipated. Izuku stood in the exact center of the tunnel, entirely untouched. Not a single drop of sludge had made it past his atmospheric shield. His uniform was perfectly clean.

 

He calmly opened his eyes and looked at the shivering, scattered globs of slime coating the tunnel. The villain's eyes and teeth were embedded in a puddle near the wall, entirely incapacitated and groaning in pain.

 

"Attempted possession," Izuku muttered, pulling a small, plastic grocery bag from his backpack. "I should probably bottle him up for the police."

 

"HAVE NO FEAR, CITIZEN!"

 

A booming voice shook the tunnel, rattling the dust from the concrete ceiling.

 

A massive figure landed at the entrance of the overpass, a silhouette of rippling muscle and golden hair. The Symbol of Peace, All Might, stood tall, a bright, confident smile plastered across his face.

 

"BECAUSE I AM—" All Might froze, his heroic pose faltering as he took in the scene.

 

He looked at the splattered, utterly defeated Sludge Villain coating the walls. Then he looked at the polite, green-haired middle schooler holding a plastic grocery bag.

 

"Ah," All Might blinked. "It seems... you handled it?"

 

For the first time all day, Izuku’s serene composure cracked. His eyes went wide. His jaw dropped. The notebook slipped from his hands.

 

"A-A-All Might?!" Izuku squeaked, his fanboy instincts entirely overriding his stoic martial arts discipline. "You're All Might! In the flesh! Oh my goodness, the pressure displacement of your landing was incredible, at least five hundred pounds of force per square inch, and your—!"

 

All Might let out a booming laugh, quickly gathering the incapacitated villain into two large plastic soda bottles. "You have a sharp eye, young man! And an incredibly powerful Quirk, it seems! To take down a villain like this on your own... you have the makings of a fine Pro Hero!"

 

Izuku blushed furiously, bowing repeatedly. "T-Thank you! Could you please sign my notebook?!"

 

All Might signed the book in a blur of speed. "There you go! Now, I must get this evildoer to the authorities! Stay safe, young man!"

 

With a mighty flex of his legs, All Might launched himself into the sky, leaving a gust of wind in his wake.

 

Izuku stood there for a moment, clutching his autographed notebook to his chest, grinning like a fool. He had met his idol. And his idol had praised him. It was the greatest day of his life.

 

He secured the notebook in his bag and continued his walk home, feeling like he was walking on air. (Technically, he could walk on air, but today, he was happy to use the pavement).

 

 The Vacuum

 

Ten minutes later, the illusion of a perfect day was violently shattered.

 

A massive explosion rocked the city, sending a plume of black smoke spiraling into the afternoon sky. Izuku felt the shockwave in his teeth. He felt the rapid change in air temperature, the sudden influx of carbon dioxide, and the chaotic, swirling wind patterns born from extreme heat.

 

A fire, Izuku analyzed instantly. A big one. Just a few blocks away.

 

Without thinking, he sprinted toward the smoke. He didn't run like a normal person; he utilized a technique he called Slipstream. He manipulated the air resistance in front of him, creating a localized aerodynamic tunnel that entirely removed drag, while simultaneously pushing a current of high-pressure air against his back. He moved with terrifying, effortless speed, covering three city blocks in a matter of seconds.

 

He arrived at the Tatooin Shopping District.

 

The scene was pure chaos. The alleyway was engulfed in roaring flames, the heat warping the air. A massive crowd of onlookers was held back by the police. Pro Heroes—Death Arms, Mt. Lady, and Kamui Woods—were standing helplessly on the sidelines.

 

"It's no good!" Death Arms shouted, coughing through the smoke. "I can't get close! The heat is too intense!"

 

"I need at least a two-lane road to maneuver!" Mt. Lady complained, shielding her face.

 

Kamui Woods was useless against the fire, and Backdraft was struggling to keep the flames from spreading to the adjacent buildings.

 

Izuku pushed his way to the front of the crowd, his eyes scanning the disaster.

 

And then, he saw him.

 

In the center of the inferno, the Sludge Villain had reformed. Somehow, he had escaped All Might. He was vastly larger now, engorged on the ambient sewage and trash in the alley. But that wasn't what made Izuku’s blood run cold.

 

Trapped inside the sludge, suffocating, thrashing with desperate, violent explosions, was Katsuki Bakugo.

 

Katsuki’s eyes were bloodshot, his mouth open in a silent scream as the sludge forced its way down his throat. He was drowning. He was dying.

 

Izuku heard the heroes talking.

 

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

 

"If only All Might were here!"

 

"We can't do anything!"

 

Wait? Izuku’s mind raced. He doesn't have time to wait. Three minutes without oxygen causes permanent brain damage. Four minutes causes death. He's already been in there for at least a minute. Waiting is murder.

 

Izuku didn't think. He didn't plan. The Baguazhang philosophy dissolved, replaced by a pure, unadulterated instinct to protect.

 

Before the police could stop him, Izuku stepped past the barricade.

 

"Hey! Kid! Get back here! Are you crazy?!" Death Arms reached out to grab him, but his hand closed on empty air.

 

Izuku was already walking into the inferno.

 

He didn't run. He walked with slow, deliberate, terrifying purpose. His green eyes glowed with an ethereal, predatory focus. He raised his hands, his fingers splayed.

 

"Fire," Izuku murmured softly to himself, "requires oxygen."

 

Izuku swept his arms outward in a broad, parting motion, like a conductor commanding an orchestra.

 

The results were instantaneous and god-like.

 

He forcibly ripped the oxygen molecules out of the air in a ten-foot corridor directly in front of him. Without oxygen, the roaring, towering flames simply vanished. They didn't blow out; they ceased to exist, winking out of reality and leaving behind nothing but smoking, scorched concrete.

 

The crowd gasped. The Pro Heroes stared in utter disbelief. A fourteen-year-old boy had just parted a sea of fire as easily as Moses parting the Red Sea.

 

The Sludge Villain looked up, his gloating turning to absolute horror as he recognized the green-haired boy walking toward him through the extinguished flames.

 

"YOU!" the villain shrieked. "You're the brat from the tunnel! Stay away from me! I have a hostage this time! You try that pressure trick again, and I'll crush this kid's neck!"

 

Katsuki, through the haze of suffocation, locked eyes with Izuku. Katsuki’s eyes were wide, filled with a mixture of desperate relief and absolute humiliation. Deku...

 

"You're right," Izuku said, his voice carrying clearly over the crackling embers. He didn't stop walking. Ten paces. Five paces. "An omnidirectional pressure blast would severely injure Kacchan. It's a blunt-force tactic. Inefficient."

 

Izuku stopped ten feet away from the monstrous sludge behemoth. He lowered his stance.

 

"Luckily for him," Izuku said, raising his right hand, his index and middle fingers extended like a gun. "I am not a blunt instrument. I am a scalpel."

 

Baguazhang Form 8: The Void.

 

Izuku didn't blast the villain. He didn't use wind. He used the most lethal, terrifying aspect of his Quirk.

 

He pinpointed the exact location of the Sludge Villain's central nervous system—the eyes and the teeth—and created a perfect, hermetically sealed, one-foot vacuum sphere around it.

 

Simultaneously, using his left hand, he gathered a condensed pocket of pure, oxygen-rich air and wrapped it securely around Katsuki’s face like an invisible scuba mask.

 

The effect was instantaneous and brutal.

 

The Sludge Villain's eyes bulged grotesquely. Inside the vacuum bubble, the pressure dropped to absolute zero. The moisture on the villain's eyes immediately boiled off in the vacuum. His vocal cords, trapped in the void, produced no sound as he screamed. Stripped entirely of oxygen, the villain's cellular structure collapsed rapidly.

 

The massive wave of sludge lost all cohesion. It turned back into a lifeless, non-Newtonian puddle, melting away from Katsuki’s body in a matter of seconds.

 

The villain's eyes rolled back into his head, and with a sickening splat, the core of the villain collapsed onto the pavement, completely unconscious, suffocated in less than ten seconds.

 

Katsuki dropped to his hands and knees, coughing violently, hacking up green slime as he gasped the rich, oxygenated air Izuku was feeding him.

 

The alley was dead silent.

 

The roaring fire was gone. The towering villain was defeated. And standing in the center of the destruction, looking entirely unfazed, was a middle schooler with a notebook in his backpack.

 

In the back of the crowd, hidden in his skeletal, un-muscled form, Toshinori Yagi—All Might—gripped a telephone pole, his blue eyes wide with shock. He had rushed here, cursing his own limitations, despising himself for running out of time. He had watched the heroes do nothing.

 

And then, he had watched this boy—the same boy from the tunnel—do the impossible. The boy hadn't just defeated the villain; he had dissected him with the clinical precision of a master surgeon, utilizing a level of Quirk control that defied logical explanation.

 

That boy... Toshinori thought, his heart hammering against his ribs. His power... it's terrifying. But his eyes... he didn't hesitate for a single second. He moved to save a life when no one else would.

 

The silence in the alley broke as Death Arms and Kamui Woods finally shook off their stupor and rushed forward.

 

"Kid!" Death Arms yelled, grabbing Izuku by the shoulder, spinning him around. "What the hell were you thinking?! You could have been killed! You interfered with official hero work! You—!"

 

Death Arms stopped. He looked into Izuku’s eyes. He expected to see the reckless adrenaline of a child who had made a stupid mistake.

 

Instead, he saw the calm, oceanic depth of someone entirely in control.

 

"The hostage had approximately thirty seconds before irreversible hypoxia set in," Izuku stated calmly, his voice polite but firm. "Your Quirks were incompatible with the thermal output of the fire. The logical course of action was immediate, targeted intervention. The threat is neutralized. The hostage is breathing. The fire is contained. You can proceed with the arrest, sir."

 

Death Arms opened his mouth to scold him again, but the words died in his throat. How could he reprimand a kid who had just done their job perfectly, flawlessly, in less than a minute?

 

Nearby, Mt. Lady was helping Katsuki up. Katsuki shoved her away, his legs shaking, his pride shattered into a million pieces. He looked at Izuku.

 

Izuku met his gaze. He didn't look smug. He didn't look down on Katsuki. He just looked relieved.

 

Katsuki gritted his teeth, tears of sheer frustration prickling his eyes. He didn't say thank you. He couldn't. He just turned and limped toward the paramedics, his hands clenched into fists so tight his palms bled. Dammit. Dammit! I was helpless. He saved me... again. He didn't even break a sweat.

 

As the police moved in to clean up the mess and officially arrest the unconscious slime, Izuku quietly slipped away. He didn't want the applause of the crowd that was just starting to cheer. He didn't want the media's cameras. He had done what was necessary, nothing more.

 

He walked out of the alley, the setting sun casting long, golden shadows across the pavement.

 

The air around him was calm.

 

"Young man! Wait!"

 

Izuku paused, turning around.

 

A gaunt, skeletal man with messy blonde hair was jogging toward him, coughing up a small amount of blood into a handkerchief. Izuku tilted his head, his analytical mind instantly noticing the man's recessed eye sockets, the baggy clothing, and the lingering, faint scent of ozone and... power.

 

"Can I help you, sir?" Izuku asked politely.

 

Toshinori Yagi stopped a few feet away, catching his breath. He looked at the boy, truly seeing him for the first time. He saw the intelligence, the restraint, and the quiet, undeniable strength.

 

"I saw what you did back there," Toshinori said, his voice surprisingly deep and commanding for a man of his frail stature. "The Pro Heroes were frozen. The crowd was frozen. But you... you stepped into the fire."

 

"He was dying," Izuku said simply, as if that were the only justification needed. "Someone had to act."

 

Toshinori smiled, a genuine, warm expression that reached his sunken eyes. "Yes. Someone did. Tell me, young man... what is your name?"

 

"Izuku. Izuku Midoriya."

 

Toshinori nodded slowly. "Izuku Midoriya. You have an incredible gift. But more importantly, you have the heart of a true hero. Ten months from now, the UA High School entrance exams will begin."

 

Izuku’s eyes widened slightly. "How did you know I was applying?"

 

Toshinori chuckled, wiping his mouth. "A hunch. I have a feeling, Midoriya, that when you walk through those gates... you are going to change the world. Keep training. Keep that restraint. Because power like yours... it can be a heavy burden."

 

Toshinori bowed slightly and turned to walk away, disappearing into the evening crowd.

 

Izuku stood on the sidewalk, the wind gently rustling his green hair. He felt a strange sense of validation, a profound shift in the atmosphere of his own life. The path ahead was clear.

 

He didn't just want to be a hero anymore.

 

He was going to be the storm that washed away the darkness, and the gentle breeze that guided people home.

 

He closed his eyes, took a deep breath, and let the air carry him forward.

 

 

 

 

The ten months leading up to the UA High School Entrance Exam were not spent cleaning a beach. Izuku Midoriya had already done that. Dagobah Municipal Beach was pristine, a quiet expanse of white sand and crashing waves where Izuku had spent the last three years perfecting his Baguazhang.

 

Instead, Izuku spent those ten months refining the most dangerous aspect of his Quirk: restraint.

 

He knew that the UA Entrance Exam involved destroying robots. The internet forums were full of rumors about it. But destroying a machine was dangerously easy for someone who could summon localized natural disasters. His true test was precision. He needed to ensure that when he unleashed his power, the shrapnel wouldn't hit other examinees. He needed to ensure that his air-pressure implosions wouldn't burst the eardrums of the kids running next to him.

 

He spent the winter on the peak of a secluded mountain, meditating in sub-zero temperatures. He wore only a t-shirt and shorts, relying entirely on his Quirk to rapidly vibrate the air molecules around his skin, creating a thermal barrier to keep himself warm. He learned to isolate his Quirk's effects to a millimeter above his epidermis, ensuring perfectly localized control.

 

By the time spring arrived, Izuku Midoriya was not just prepared. He was a finely tuned instrument of atmospheric physics, wrapped in the unassuming guise of a fifteen-year-old boy.

 

 Arrival at UA

 

The morning of the exam, the air was crisp and cool. The cherry blossoms were in full bloom, their pink petals dancing on the gentle morning breeze.

 

As Izuku walked up the sprawling, paved pathway toward the towering glass-and-steel monolith of UA High School, he didn't just feel the breeze; he saw it. Through his Quirk’s unique spatial awareness, he could feel the exact trajectory of every falling petal, mapping the invisible currents of wind that carried them.

 

He took a deep breath, the oxygen filling his lungs, calming his nerves. This is it. The proving ground.

 

He was so lost in his atmospheric calculations that he entirely forgot to monitor his own two feet. The toe of his red sneaker caught the lip of a raised paving stone.

 

Gravity took hold. Izuku pitched forward, his arms flailing slightly as the concrete rushed up to meet his face.

 

Whoops, he thought, entirely unbothered.

 

He didn't brace for impact. He didn't even close his eyes. In a fraction of a second, his brain made the necessary calculations. He forcefully drew the ambient air beneath his chest and compressed it. The molecules packed tightly together, forming a dense, invisible cushion of solid barometric pressure.

 

Izuku stopped falling. He hung in mid-air, suspended at a forty-five-degree angle, hovering six inches above the pavement like a mime performing a trick.

 

"Whoa! Are you okay?!"

 

A girl with a bob of chestnut hair and bright, round eyes stepped forward, her hand outstretched as if to catch him. But she blinked, her hand hovering in the empty space above his back, realizing he wasn't falling anymore.

 

Izuku shifted his weight, adjusting the air density beneath his feet to gently push himself back into a standing position. He turned to look at the girl, offering a polite, slightly embarrassed smile.

 

"I'm fine, thank you," Izuku said, brushing a stray cherry blossom petal from his shoulder. "I wasn't looking where I was going."

 

The girl stared at him, her jaw slightly dropped. She waved her hand under his feet, finding nothing but empty air. "How did you do that?! You were totally falling, and then you just... stopped! Are you floating? Is your Quirk like mine?"

 

"Not quite," Izuku replied, his analytical mind immediately catching her implication. "Your Quirk negates gravity? That's incredible. The applications for rescue operations and structural support are limitless."

 

The girl beamed, a bright blush dusting her cheeks. "Yeah! Zero Gravity! I'm Ochaco Uraraka. I was gonna catch you, but it looks like you caught yourself!"

 

"Izuku Midoriya," he replied with a small bow. "And I don't control gravity. I just increased the air density beneath my body to create a localized high-pressure cushion, effectively turning the atmosphere into a solid support structure."

 

Uraraka blinked, her smile freezing for a second as her brain tried to process the physics lesson. "Uh... wow. That sounds super complicated. But really strong! Well, it's nice to meet you, Midoriya! Let's both do our best today!"

 

She pumped her fist enthusiastically and jogged ahead toward the massive entrance doors.

 

Izuku smiled. The nerves were entirely gone. If the other applicants were as nice as Uraraka, UA was going to be a wonderful place.

 

 The Orientation

 

The written exam was trivial. Izuku finished it in half the allotted time, his mind easily processing the advanced calculus and hero-law questions.

 

The orientation for the practical exam took place in a massive, darkened auditorium. Pro Hero Present Mic stood on the stage, screaming into a microphone, desperately trying to hype up a crowd of highly stressed teenagers.

 

"CAN I GET A HEYYYY?!" Present Mic roared.

 

Silence.

 

Izuku sat in his assigned seat, his hands resting on his knees. To his right sat Katsuki Bakugo.

 

The explosive blonde hadn't said a word to Izuku all morning. In fact, Katsuki had been terrifyingly quiet for months. There was no arrogant slouch, no feet on the desk. Katsuki sat perfectly upright, his arms crossed over his chest, his crimson eyes locked onto the presentation screen with predatory intensity. He was radiating a silent, focused heat. Izuku could literally feel the air temperature rising around Katsuki as the boy’s nitroglycerin sweat glands worked in overdrive.

 

Present Mic explained the rules. A mock cityscape. Ten minutes. Four types of robots. Three of them awarded points based on difficulty—one, two, and three points respectively. The fourth robot was a Zero Pointer, an obstacle meant to be avoided.

 

Suddenly, a tall boy with glasses and perfectly combed blue hair stood up, rigid as a board. "Excuse me, sir! But you have made an error! The printout lists four types of villains, but you only explained three! If this is an error on UA's part, it is highly shameful for Japan's premier academy!"

 

The boy then turned around, pointing a stiff, accusatory finger directly at Izuku. "And you, with the unkempt hair! You have been sitting perfectly still, staring straight ahead without taking a single note! If you aren't taking this seriously, I suggest you leave!"

 

The auditorium went quiet. Hundreds of eyes turned to Izuku.

 

Katsuki’s eye twitched. He leaned slightly toward the blue-haired boy. "Hey, Four-Eyes," Katsuki growled, his voice a low, terrifying rasp. "If I were you, I'd shut my mouth and sit down before you embarrass yourself."

 

The blue-haired boy gasped, offended. "What crass behavior!"

 

Izuku, however, didn't look embarrassed. He calmly turned his head to look at the boy with glasses. His expression was serene, his voice carrying clearly without him needing to raise it.

 

"Notes are unnecessary when you possess eidetic memory recall, but I appreciate your concern," Izuku said politely. "Furthermore, Present Mic was just about to explain the fourth robot before you interrupted his cadence. As for the test's parameters... a true hero assessment wouldn't solely grade on destruction. There is undoubtedly a hidden metric we are meant to discover in the field. I suggest you focus on your own readiness rather than policing the crowd."

 

The blue-haired boy blinked, utterly thoroughly dismantled by the calm, polite logic. He flushed a deep red, bowed stiffly, and sat down in silence.

 

Present Mic coughed into his microphone. "Uh, right! Thank you, Examinee 7111! Like the kid said, the fourth robot is a Zero Pointer! Just a massive obstacle! Avoid it! Now, make sure you're ready to go PLUS ULTRA!"

 

 The Practical Exam Begins

 

The examinees were herded to Test Area B. It was a staggering sight—an entire, life-sized replica of a metropolitan city, complete with skyscrapers, roads, and alleyways, all walled off by a massive steel perimeter.

 

Dozens of teenagers stretched, bounced, and paced nervously in front of the giant gate. Izuku stood near the back of the crowd. He closed his eyes, sliding his left foot forward and his right foot back, sinking into a relaxed, grounded Baguazhang stance.

 

He pushed his awareness outward.

 

His Quirk, Atmospheric Manipulation, allowed him to feel the air. Right now, he could feel the nervous, shallow breathing of the fifty applicants around him. He could feel the heat rising from their skin. But he pushed further. He sent his senses over the towering gate, into the mock city.

 

He felt the heavy, rigid, metallic displacement of air. Hundreds of them. The robots were idling in the streets, waiting. He mapped their locations in his mind, feeling the subtle vibrations of their cooling fans and exhaust ports.

 

"START!"

 

Present Mic’s voice echoed from a massive speaker tower.

 

The other applicants froze. They looked at the gates, waiting for a countdown.

 

"WHAT ARE YOU WAITING FOR?!" Present Mic yelled. "THERE ARE NO COUNTDOWNS IN REAL BATTLES! RUN, RUN, RUN!"

 

The crowd panicked and surged forward as the gates slowly began to open.

 

Izuku didn't run.

 

He took a sharp breath in. He created a microscopic pocket of absolute vacuum directly in front of his body, entirely eliminating all air resistance and drag. Simultaneously, he gathered a massive volume of highly compressed air directly behind his back.

 

He released the compression.

 

BOOM.

 

A sonic boom shattered the morning air. A shockwave kicked up a cloud of dust that blinded the applicants at the starting line.

 

Before anyone could even blink, before the gates had even fully opened, Izuku Midoriya was gone. He shot through the gap in the doors at supersonic speed, moving so fast he was nothing but a green blur.

 

"What the... what was that?!" a boy yelled, coughing in the dust.

 

"Did he just fly?!"

 

Izuku rocketed down the main avenue of the mock city. The wind roared in his ears, but he controlled it, parting the air around his face so he could see perfectly. He approached the first intersection.

 

Target acquired.

 

Three 3-Point robots turned the corner. They were massive, tank-like treads rumbling against the asphalt, their mechanical red eyes locking onto Izuku. "TARGET SPOTTED."

 

Most applicants would stop, brace themselves, and prepare to fight.

 

Izuku didn't even slow down.

 

As he closed the gap, moving at seventy miles per hour, he swept his right arm horizontally through the air. He didn't generate a gust of wind. He generated a shear. He took the ambient air in front of the robots, compressed it to the width of a single atom, and accelerated it to Mach 3.

 

An invisible, crescent-shaped blade of pure atmospheric pressure tore through the street.

 

SHNK.

 

The sound was clean, like a katana slicing through wet bamboo.

 

Izuku skidded to a halt fifty feet behind the robots, his sneakers smoking slightly on the pavement.

 

For a second, nothing happened. The three 3-Pointers stood perfectly still.

 

Then, the top half of all three robots slowly slid off their chassis. The massive steel plates, thick hydraulic cables, and reinforced armor had been sheared perfectly in half on a horizontal axis. The metal groaned, and the top halves crashed onto the pavement, exploding in a shower of sparks and smoke.

 

Nine points, Izuku calculated mentally. Four seconds elapsed.

 

He didn't admire his work. He could feel more displaced air two streets over. He bent his knees and launched himself into the sky, riding a geyser of compressed air up to the roof of a five-story building.

 

He looked down into the courtyard below. A massive swarm of 1-Pointers and 2-Pointers—at least twenty of them—were rolling out, cornering several terrified examinees, including the blue-haired boy with glasses.

 

The boy—Iida—was kicking the robots with engines in his calves, but there were too many. "Fall back!" Iida shouted to the others. "We're outnumbered!"

 

From the roof, Izuku raised his hands, his palms facing each other. He began to move his arms in a slow, circular motion, like he was rolling a giant ball of dough.

 

In the courtyard below, the air began to spin.

 

"What the—?" Iida yelled, holding his arm up as a fierce gale picked up.

 

Izuku wasn't making a tornado to blow them away. He was creating a localized cyclonic vortex to group them together. The high-speed winds ripped the robots off the ground, tossing their heavy metal chassis around like children's toys, dragging all twenty of them into the exact center of the courtyard. The robots clanged and smashed against each other, a massive, tangled ball of machinery trapped in the eye of the storm.

 

Izuku stopped spinning his hands. He clasped them together, interlacing his fingers.

 

Implode.

 

Izuku drastically dropped the air pressure inside the tangle of robots, while simultaneously pulling the weight of the atmosphere down upon them.

 

The physics were undeniable. The pressure of the earth's atmosphere is roughly 14.7 pounds per square inch. But if Izuku multiplied that localized pressure by a factor of one thousand...

 

CRUNCH.

 

The deafening sound of shrieking metal echoed across the city block.

 

The twenty robots didn't explode. They were crushed inward. Steel beams buckled like tin foil. Camera lenses popped. Hydraulic fluid sprayed like blood as the entire mass of twenty robots was instantly compacted into a perfectly dense, spherical ball of scrap metal no larger than a compact car.

 

The crushed sphere dropped to the pavement with a heavy, earth-shaking THUD.

 

Down in the courtyard, Iida and the other examinees stared at the ball of scrap metal in absolute, paralyzed horror.

 

"Thirty points," a calm voice drifted down.

 

They looked up. Izuku was standing on the edge of the roof, his hands casually resting in his pockets. He gave them a polite nod. "The intersection is clear. Good luck," he said, before casually stepping backward off the roof and letting the wind carry him away.

 

 The Unseen Observer

 

Deep within the bowels of UA, in a dark, high-tech observation room, the faculty of UA High School sat in stunned silence.

 

The wall was plastered with dozens of monitors showing different feeds from the mock cities. But right now, almost every Pro Hero in the room had their eyes glued to Monitor 4, tracking Examinee Midoriya.

 

"Good god," breathed Vlad King, the Blood Hero. "Did you see the sheer tensile strength of that air compression? He crushed twenty tons of reinforced steel without moving a muscle."

 

Snipe adjusted his mask. "His reaction time is off the charts. He's moving faster than the cameras can pan. But it's not wild. Every move is calculated. He hasn't caused a single piece of collateral damage to the buildings."

 

Sitting in the front row, wrapped in his yellow sleeping bag, Shota Aizawa—Eraserhead—stared at the screen, his dark, tired eyes narrowed. Aizawa hated flashy, destructive Quirks. They usually came with arrogant, reckless personalities. But this kid... this kid was different.

 

"He's not fighting," Aizawa mumbled, his voice cutting through the chatter.

 

"What do you mean, Eraser?" asked Midnight.

 

"Look at his footwork. Look at his breathing," Aizawa pointed a bandaged finger at the screen. Izuku was currently gliding effortlessly between two buildings, using air currents to dodge laser fire from a 3-Pointer before casually decapitating it with a vacuum blade. "He's not throwing punches. He's performing martial arts. Baguazhang, if I'm not mistaken. He has perfectly married his Quirk to his physical movements. He's treating the robots like training dummies."

 

Nezu, the chimera principal of UA, sat on his elevated chair, sipping a cup of tea, his beady eyes gleaming with intense fascination. "Fascinating. A mutant-class elemental emitter Quirk with near-infinite scaling potential. If he wanted to, he could suffocate every applicant in that city in three seconds. But he's actively restraining himself. He is using precise, surgical applications of pressure to avoid causing sonic booms near his classmates."

 

Nezu turned to look at the skeletal, blonde man standing in the back corner of the room. Toshinori Yagi was gripping the railing, his eyes wide, a proud, knowing smile on his face.

 

"You've found an interesting one, All Might," Nezu chuckled. "He has already shattered the all-time combat score record. And there are still three minutes left."

 

Aizawa sighed. "Let's see how the boy handles an insurmountable obstacle. Release the Zero Pointer."

 

Nezu slammed his paw down on a big red button.

 

 The Zero Pointer

 

Back in Test Area B, Izuku landed lightly on a street light. He mentally checked his score.

 

Eighty-six points. That should be more than enough to secure a passing grade.

 

The exam was almost over. The other examinees were exhausted, panting, and frantically searching for scraps. Izuku hadn't even broken a sweat. His breathing was perfectly even.

 

Suddenly, the ground began to tremble.

 

It wasn't a small vibration. The asphalt cracked. Windows in the nearby buildings shattered. A shadow fell over the main avenue, blocking out the morning sun.

 

Izuku looked up.

 

At the end of the street, a monstrosity of metal and treads tore through two skyscrapers as if they were made of cardboard. The Zero Pointer. It was the size of a skyscraper itself, a towering, heavily armed juggernaut of destruction.

 

"Less than two minutes left!" Present Mic’s voice blared over the sirens.

 

The examinees screamed.

 

"Run!"

 

"Are they insane?! We can't fight that thing!"

 

The crowd of teenagers turned and sprinted in the opposite direction, absolute terror painting their faces.

 

Izuku prepared to jump away. There was no tactical advantage in fighting a Zero Pointer. It awarded no points. The logical move was retreat.

 

But as he shifted his weight, his Quirk picked up a soundwave.

 

It was faint, drowned out by the grinding treads of the behemoth, but the sound traveled through the air, directly to his eardrums.

 

“Ow... my leg... somebody, please help!”

 

Izuku snapped his head around. Near the base of the Zero Pointer, amidst the rubble of the destroyed buildings, a girl was trapped. A massive chunk of concrete had pinned her ankle.

 

It was the girl from the entrance. Uraraka.

 

The Zero Pointer raised a massive, hydraulic fist, preparing to smash the street into dust. Uraraka squeezed her eyes shut, crying out as the shadow fell over her.

 

The logical, analytical part of Izuku’s brain shut off. The Baguazhang philosophy of yielding and redirection vanished.

 

There was no yielding to a mountain. Sometimes, a hurricane just had to tear the mountain down.

 

Izuku leaped off the street light.

 

He didn't glide. He didn't float. He created a series of high-pressure kinetic explosions beneath his feet, rocketing into the air with the speed and violence of a surface-to-air missile.

 

The applicants running away stopped, turning back in shock as a green blur streaked past them, heading straight for the colossal machine.

 

"What is he doing?!" Iida screamed. "He's going to get himself killed!"

 

Izuku didn't hear them. He ascended rapidly, flying up to eye level with the Zero Pointer's massive, glowing red optical sensor, two hundred feet in the air.

 

He hovered there, dwarfed by the sheer scale of the machine.

 

He pulled his right arm back, his hand open, palm facing the robot. He closed his eyes and dug deep into the reserves of his power. He wasn't just pulling the ambient air now. He was pulling the atmosphere from a mile radius.

 

The winds began to howl.

 

Down below, the applicants had to shield their eyes as a massive gale swept through the city, funnelling upward toward the boy in the sky.

 

Izuku compressed the air into the palm of his hand. He packed the molecules so tightly, so densely, that the laws of thermodynamics began to violently assert themselves. As the gas compressed, the temperature skyrocketed.

 

A sphere of air materialized in Izuku’s palm. But it wasn't invisible. The sheer friction and heat of the compressed oxygen and nitrogen caused the air to ignite into plasma. The sphere glowed with a blinding, ethereal blue-white light, radiating a heat that warped the air around him.

 

Air Cannon, Izuku thought.

 

The Zero Pointer's sensors flared. "DANGER. DANGER. IMMINENT THREAT DETECTED." The massive robot swung its hydraulic fist toward the tiny boy.

 

Izuku opened his eyes. They were glowing with the fierce, unyielding light of a storm.

 

He thrust his palm forward and released the compression.

 

KRA-KOOOOOOM!

 

The sound was apocalyptic. It was louder than thunder. It was the sound of the atmosphere ripping itself apart.

 

A hyper-compressed, concentrated pillar of wind and plasma erupted from Izuku’s hand. The recoil alone created a shockwave that shattered every remaining window in a three-block radius.

 

The Air Cannon struck the Zero Pointer square in the center of its chest plate.

 

The reinforced armor, designed to withstand point-blank tank fire, didn't even slow the blast down. The pillar of wind punched through the steel as if it were wet tissue paper, traveling straight through the internal mechanics, tearing through the engine block, and bursting out the back of the robot in a shower of molten metal and debris.

 

The fist that was swinging toward Izuku stopped dead in the air.

 

The robot's red optical sensor flickered, then died.

 

For a single, agonizing second, the colossal machine hung in the air, a massive, gaping hole, thirty feet in diameter, blown completely through its torso.

 

Then, the internal explosions began. The decapitated top half of the robot blew off its hinges, and the massive machine began to slowly, spectacularly collapse backward, away from Uraraka, crashing into the ruined cityscape in a deafening avalanche of scrap metal.

 

Silence descended upon Test Area B.

 

The sirens had stopped. The wind died down. The only sound was the crackle of localized electrical fires from the ruined robot.

 

High above, Izuku let out a long exhale. He lowered his arm. It was slightly red from the thermal kickback of the plasma, but otherwise unharmed. He didn't break a single bone. He didn't even strain a muscle.

 

He calmly descended from the sky, floating down like a leaf until his sneakers touched the pavement right next to the trapped Uraraka.

 

The chestnut-haired girl was staring at him, her eyes wide with absolute, unadulterated awe. She looked from the boy, to the ruined mountain of metal, and back to the boy.

 

Izuku crouched down. He raised a finger and pointed it at the slab of concrete pinning her leg. He created a small, localized high-pressure zone beneath the rock and simply lifted it up, tossing it aside with a flick of his wrist.

 

"Are you alright, Uraraka?" Izuku asked, offering her his hand, his voice as calm and polite as it had been at the entrance gates.

 

Uraraka took his hand, letting him pull her up. "Y-Yeah. I... you... that was..." She couldn't form words.

 

"TIME'S UP!" Present Mic’s voice echoed across the devastated city.

 

The exam was over.

 

The other applicants slowly walked back toward the center of the street. They formed a wide circle around Izuku, staring at him as if he were an alien. Even Iida stood completely paralyzed, his jaw tight.

 

He saved her, Iida thought, his mind reeling. He threw away his chance to escape, faced down an impossible enemy, and destroyed it with a single attack. I... I completely misjudged him.

 

"Alright, alright, good work everyone!" A small, elderly woman with a syringe walking stick hobbled through the crowd. Recovery Girl. She handed out gummies and began assessing injuries.

 

She walked up to Izuku. "You're the one who caused that terrifying blast, aren't you, sonny? Let me see your arms. Usually, Quirk blowback like that shatters the bones."

 

Izuku rolled up his sleeves, presenting his perfectly intact arms. "No blowback, ma'am. Just a slight thermal burn on the epidermis from the plasma ignition, but my localized thermal barrier mitigated 99% of the damage. I'm completely uninjured."

 

Recovery Girl blinked, looking at his flawless skin, then up at his serene face. She chuckled softly. "Well, aren't you a terrifyingly competent young man. Have a gummy."

 

Izuku took the candy, bowed deeply, and turned to walk out of the gates.

 

He had done everything he could. The rest was up to the judges.

 

 The Result

 

One week later, Izuku sat at his desk in his bedroom, intensely analyzing the fluid dynamics of a hurricane forming off the coast of Kyushu.

 

"Izuku!" Inko Midoriya’s voice pierced the quiet. She practically kicked his bedroom door open, tears already streaming down her face, waving a thick, sealed envelope with the UA crest stamped in wax. "It's here! The letter is here!"

 

Izuku set his pen down. He took the envelope from his trembling mother. "Thank you, Mom."

 

She left the room to give him privacy, pacing nervously in the hallway.

 

Izuku opened the envelope. A small, metal disk slid out and clattered onto his desk.

 

A holographic projector clicked on, casting a massive, three-dimensional projection of All Might against Izuku’s wall.

 

"I AM HERE, AS A PROJECTION!" All Might boomed, wearing a sharp yellow suit. "Young Midoriya! I have been eagerly awaiting this moment! You see, I am not just the Symbol of Peace... I am the newest faculty member at UA High School!"

 

Izuku’s eyes widened slightly. All Might teaching at UA? That explained why he was in the city.

 

"Your written exam was flawless, Midoriya! A perfect score!" All Might continued, his holographic form leaning forward. "But the practical exam... my boy, you didn't just pass. You redefined the standard."

 

A scoreboard materialized next to All Might’s head.

 

"Eighty-six villain points! A staggering achievement!" All Might beamed. "But a hero course that only graded on destruction wouldn't be much of a hero course, would it?! How can we call ourselves heroes if we ignore those in need?!"

 

The video feed of Izuku blowing the Zero Pointer into the stratosphere played in the corner of the projection.

 

"You stepped up when no one else would! You faced an insurmountable threat to protect a fellow examinee! And for that, the judging panel awarded you... RESCUE POINTS!"

 

The scoreboard updated.

 

Examinee: Izuku Midoriya

Villain Points: 86

Rescue Points: 60

Total Score: 146

 

"One hundred and forty-six points!" All Might roared proudly. "You shattered the all-time UA record! You blew right past my own score from my youth!"

 

All Might reached a hand out, pointing directly at Izuku through the hologram.

 

"Come, Young Midoriya. This is your Hero Academia!"

 

The projection clicked off, leaving Izuku sitting in the quiet glow of his desk lamp.

 

He looked at his hands. The hands that could command the sky, crush steel, and suffocate monsters. He had the power of a god, but today, he was recognized for his humanity.

 

He clenched his fist, a genuine, blinding smile breaking across his face.

 

I'm in.

 

 

 

 

To Izuku Midoriya, a room was never just a room.

 

When he slid open the massive door to Class 1-A on his first day at UA High School, he didn't just see twenty desks, a blackboard, and a podium. He immediately registered the architectural volume of the space. He felt the steady, mechanical hum of the ventilation system pumping chilled air from the ceiling grates. He mapped the thermal blooms of nineteen other human bodies, the microscopic currents of air shifting every time someone breathed, spoke, or moved.

 

He was intimately connected to the atmosphere of the room before he even took his first step inside.

 

"Take your feet off that desk immediately!"

 

Izuku blinked, his focus snapping back to the visual spectrum. Tenya Iida, the blue-haired boy from the entrance exam, was chopping his arms aggressively at Katsuki Bakugo.

 

Katsuki was slouched in his chair, his feet propped up on his desk, his crimson eyes staring out the window with a look of intense, brooding concentration. He didn't even look at Iida.

 

"It is disrespectful to the upperclassmen who sat here before us, and to the artisans who crafted the desk!" Iida lectured, adjusting his glasses.

 

Katsuki slowly turned his head. His eyes were devoid of their usual explosive rage. Instead, they were cold, flat, and dangerously quiet. "Shut up, Four-Eyes. I'm thinking."

 

Iida recoiled slightly, taken aback by the sheer, suppressed intensity radiating from the blonde boy.

 

Izuku stepped into the classroom. The quiet swish of the door closing behind him was enough to draw the attention of the room.

 

"Ah! It's him!"

 

Iida spun on his heel and marched straight toward Izuku. To Izuku's mild surprise, the tall boy bowed perfectly at a strict ninety-degree angle. "I am Tenya Iida from Soumei Junior High! I must apologize! During the entrance exam, I entirely misjudged your character! You realized the practical exam had a hidden rescue metric, and you acted with true heroism while I fled! You are the superior candidate!"

 

"There's no need to apologize, Iida," Izuku said, waving his hands politely, his cheeks dusting with a faint pink. "You were acting logically based on the parameters we were given. And I didn't know about the rescue points. I just... couldn't leave her there."

 

"Deku!"

 

Ochaco Uraraka bounded into the room, her face lighting up with a radiant smile. "You made it! I knew you would! That punch—well, that weird air-blast thing—was amazing!"

 

Before Izuku could respond to the bubbly girl, his spatial awareness spiked.

 

Out in the hallway, inches from the door, the air displaced. It was a heavy, sluggish movement, accompanied by the faint rustle of thick fabric.

 

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

 

The voice was dry, raspy, and entirely devoid of enthusiasm.

 

The class froze. Out on the floor in the hallway lay a man wrapped entirely in a bright yellow sleeping bag, sipping from a juice pouch. He unzipped the bag, stood up, and stepped into the classroom. His hair was long, black, and unkempt. His eyes were bloodshot and bagged with exhaustion.

 

"I'm your homeroom teacher, Shota Aizawa. It took you lot eight seconds to quiet down. Time is a limited resource. You kids aren't rational enough."

 

Aizawa reached into his sleeping bag and pulled out a blue and white gym uniform. "Put these on and head out to the P.E. grounds. Immediately."

 

 The Quirk Apprehension Test

 

The P.E. grounds were a sprawling expanse of perfectly manicured dirt and grass. The morning sun was climbing higher, burning off the chill of the spring air.

 

Class 1-A stood in a loose cluster, murmuring in confusion.

 

"A Quirk Apprehension Test?!" the class shouted in unison.

 

"What about the entrance ceremony? The orientation?" Uraraka asked, clutching her gym shirt nervously.

 

"UA is a freestyle school. As a teacher, I run my class how I see fit," Aizawa said, turning his back to them. "In junior high, you did physical fitness tests, but you were barred from using your Quirks. That's irrational. The Department of Education is trying to standardize a world that is inherently unequal. Bakugo."

 

Katsuki stepped forward, his expression locked into a permanent, focused scowl.

 

"You finished first in the practical exam," Aizawa said. "What was your farthest softball throw in junior high?"

 

"Sixty-seven meters," Katsuki replied sharply.

 

"Try it with your Quirk. Stand in the circle. Anything goes, as long as you stay in the ring."

 

Katsuki walked into the chalk circle. He rolled his shoulder, stretching his neck. He didn't yell. He didn't boast. He just stared at the baseball in his hand. Deku crushed twenty robots by looking at them, Katsuki thought, his teeth grinding together. He blew a hole in the sky. If I want to beat him, I can't waste a single ounce of kinetic energy.

 

Katsuki wound up. As his arm snapped forward, he ignited a hyper-concentrated explosion directly against the leather of the ball, channeling the blast into a perfect, directional cone of force.

 

BOOM!

 

The shockwave rattled the teeth of the students watching. The ball vanished into the stratosphere, leaving a trail of black smoke.

 

Aizawa held up a digital tracker. It beeped. 705.2m.

 

"Know your maximum limit first," Aizawa said lazily. "That is the most rational way to form the foundation of a hero."

 

The class erupted into cheers.

 

"700 meters?! That's awesome!"

"We get to use our Quirks! This looks like fun!"

 

Aizawa’s eyes narrowed, his gaze darkening. "Fun? You have three years to become heroes. You think it's going to be games and playtime?" He smiled, a terrifying, predatory grin. "Right. Whoever comes in last place across all eight events will be judged as having no potential, and will be punished with immediate expulsion."

 

The class gasped. "Expulsion?! On the first day?!"

 

Izuku didn't gasp. He didn't even flinch. He simply stood in his relaxed, grounded Baguazhang stance, breathing deeply. He analyzed the threat. An expulsion on the first day is highly irregular, but within the legal rights of a UA instructor. However, statistically, removing a student who passed the grueling entrance exam implies a flaw in the school's own selection process. It is a logical ruse designed to draw out our maximum potential. But even if it isn't...

 

Izuku looked down at his hands. I won't be last.

 

Aizawa noticed the green-haired boy's utter lack of reaction. Midoriya, Aizawa thought. Let's see if your control is as perfect as Nezu thinks it is.

 

Test 1: 50-Meter Dash

 

Izuku stepped up to the starting line. Beside him was Tenya Iida.

 

"I look forward to seeing your capabilities, Midoriya!" Iida said, his calf engines revving up with a screeching whine. "But I will not lose on a track!"

 

"Good luck, Iida," Izuku said politely.

 

A robot with a camera stood at the finish line. "On your marks... Get set..."

 

Izuku took a breath. He didn't get into a sprinter's crouch. He stood perfectly upright.

 

He didn't need his legs to propel him. He needed aerodynamics. Drag is the aerodynamic force that opposes an object's motion through a fluid (in this case, air). At high speeds, air resistance becomes an insurmountable wall of friction.

 

Izuku simply removed the wall.

 

He manipulated the atmospheric pressure directly in front of his body, carving out a perfect, cylindrical vacuum tunnel stretching from the starting line to the finish line. Inside this tunnel, there was zero air. Zero drag. Zero resistance.

 

Simultaneously, he gathered a dense pocket of highly compressed air behind his back.

 

BANG! The starting gun fired.

 

Iida exploded off the line, his engines flaring blue as he rocketed down the track in a blur of speed.

 

But Izuku didn't run. He released the compressed air behind him while standing inside his vacuum tube.

 

With a concussive CRACK that displaced the dust in a twenty-foot radius, Izuku was shot out of an invisible atmospheric cannon. Because there was zero air resistance to slow him down, his acceleration was instantaneous and frictionless.

 

He crossed the finish line before Iida was even halfway there. He used a reverse-pressure cushion against his chest to immediately decelerate, dropping his velocity from supersonic to zero in a single footstep, perfectly balanced.

 

"1.21 seconds!" the robot announced.

 

Two seconds later, Iida crossed the line. "3.04 seconds!"

 

Iida skidded to a halt, panting, staring at Izuku in sheer disbelief. "H-How did you... I didn't even see your legs move!"

 

"I didn't run, Iida," Izuku explained gently. "I utilized a pneumatic propulsion technique by creating a pressure differential. It's essentially the same physics as a vacuum tube."

 

On the sidelines, a boy with half-white, half-red hair—Shoto Todoroki—narrowed his mismatched eyes. He didn't just move fast. He controlled the exact stopping distance. He didn't kick up dirt at the finish line. Absolute kinetic mastery.

 

Test 2 & 3: Grip Strength and Standing Long Jump

 

For the grip strength test, Izuku held the device lightly in his palm. He didn't squeeze with his muscles. He isolated the air immediately surrounding the metal grips and compressed it inward. He layered the barometric pressure until it reached the density of titanium. The machine groaned under the invisible vice before the digital screen shattered.

 

Score: Error / Overload.

 

For the long jump, Izuku simply stepped into the air. He laid down a ramp of solid, compressed wind and casually walked across the sky, passing over the sandbox entirely and landing gently on the grass on the other side.

 

The class was no longer cheering. They were watching him with a mixture of profound awe and mild terror. He wasn't sweating. His breathing hadn't elevated. He was treating the physical limits of the human body as mere suggestions.

 

Test 5: The Ball Throw

 

It was the final test. Uraraka had just scored an 'Infinity' by removing the ball's gravity.

 

"Midoriya. You're up," Aizawa called out.

 

Izuku stepped into the chalk circle. He held the small baseball in his hand. He looked up at the sky. It was a clear day, a few cumulus clouds drifting lazily at thirty thousand feet.

 

Aizawa watched him like a hawk. He hasn't shown a single flaw. No blowback, no strain. But throwing a projectile without direct physical force or a containment barrel is incredibly difficult. Let's see how you handle trajectory.

 

Izuku didn't wind up like Katsuki. He held the ball out in front of him, letting it rest on his open palm.

 

To achieve maximum distance, Izuku calculated, I need a frictionless environment, combined with rotational velocity to maintain stability, and an initial burst of hyper-compressed kinetic energy.

 

Izuku closed his eyes.

 

The air in the P.E. grounds suddenly dropped in temperature. A massive, swirling vortex of wind began to gather around Izuku's extended arm. But it wasn't a chaotic tornado. It was perfectly structured. Rings of highly compressed air stacked on top of one another, forming an invisible, rifled barrel extending from his palm into the sky, angled at exactly forty-five degrees.

 

Izuku released the ball from his hand. It didn't fall. It hovered in the center of the invisible barrel.

 

"What is he doing?" whispered a boy with red, spiky hair, Eijiro Kirishima. "The air is... vibrating."

 

Aizawa’s eyes widened slightly. He recognized the technique. It was a theoretical physics concept. A railgun. He's building an atmospheric railgun.

 

Izuku opened his eyes, flashing a serene, focused green.

 

Fire.

 

Izuku collapsed the hyper-pressurized air directly behind the ball.

 

The sound was not a boom. It was a sharp, ear-splitting CRACK that sounded like the sky itself tearing in half. A visible shockwave ring expanded from the tip of the invisible barrel.

 

The ball didn't just fly; it vanished. It ignited into a streak of red-hot plasma as it broke the sound barrier instantly, piercing through the atmosphere and punching a perfectly round hole through a cumulus cloud miles above.

 

The silence that followed was deafening, save for the wind slowly settling back into its natural state.

 

Aizawa stood perfectly still. He looked down at the digital tracker in his hand. The screen was glitching, flashing a series of numbers before finally settling on a single, undeniable symbol.

 

∞

 

Aizawa turned the screen around to show the class.

 

"Infinity," Kaminari choked out.

 

"He matched Uraraka without using gravity manipulation," Momo Yaoyorozu noted, her dark eyes wide. "He simply applied so much velocity and rotational stability that the ball escaped the earth's gravitational pull before the friction burned it up. That level of micro-calculation... it's beyond genius."

 

Izuku lowered his arm, bowing slightly to Aizawa. "Was the trajectory satisfactory, sir?"

 

Aizawa stared at the green-haired boy. He had intended to use his Erasure Quirk today to humble someone, to show them they relied too much on their power. But how could he humble a boy who was acting with such terrifying restraint and precision?

 

"It was... rational," Aizawa muttered, slipping his tracker into his pocket.

 

When the final scores were tallied, Izuku Midoriya sat comfortably at Rank 1. Katsuki Bakugo was Rank 2, Momo Yaoyorozu at 3, and Shoto Todoroki at 4.

 

"By the way, the expulsion was a logical ruse," Aizawa said flatly, ignoring the collective shriek of betrayal from the class. "It was meant to draw out your best. We're done here. Handouts are in the classroom."

 

As the class dispersed toward the locker rooms, Katsuki walked past Izuku. Their shoulders brushed.

 

"Don't get cocky," Katsuki whispered, his voice trembling slightly with suppressed adrenaline. "A track meet isn't a fight. You haven't proven anything yet."

 

Izuku didn't look at him. "I'm not trying to prove anything, Kacchan. I'm just doing my best."

 

 The Costumes

 

The afternoon sun cast long shadows across Ground Beta.

 

Class 1-A stood at the entrance of a massive, simulated urban district, waiting for their instructor. They were no longer wearing gym uniforms. They were clad in their official Hero Costumes.

 

"THEY SAY THE CLOTHES MAKE THE PRO!"

 

All Might emerged from the shadows of an access tunnel, striking a flexed pose, his booming voice echoing off the buildings. "AND YOU ALL LOOK ABSOLUTELY MARVELOUS! TRULY, THE NEXT GENERATION OF HEROES!"

 

The class marveled at each other's designs. Katsuki stood out in his aggressive black and orange suit, complete with massive, grenade-shaped gauntlets. Uraraka wore a sleek, pink and black astronaut-inspired suit. Iida looked like a walking engine block in full plate armor.

 

Then, Izuku stepped out of the tunnel.

 

His costume was a masterclass in aerodynamic efficiency, deeply inspired by his Baguazhang martial arts. It was a form-fitting, sleeveless tunic of deep, forest green, made from a specialized, frictionless compression fabric. The pants were loose around the thighs for maximum mobility, tapering to tight bindings at the ankles.

 

He didn't wear heavy boots. He wore specialized, lightweight martial arts slippers with thin soles, allowing him to feel the vibrations of the ground. He wore open-fingered gloves, leaving his palms bare to maximize his sensory connection to the air.

 

Around his neck was a simple, high-collared cowl, meant to protect his throat from windburn, but he didn't wear a mask. His face was entirely visible, his eyes bright and alert. Embedded in the trim of his suit were tiny, microscopic metallic scales that chimed faintly when the wind caught them, acting as localized barometers to help him gauge ambient pressure at a glance.

 

It wasn't flashy. It was elegant, deadly, and entirely practical.

 

All Might caught sight of Izuku and felt a swell of pride. The boy looked like a true martial artist.

 

"NOW THEN!" All Might shouted. "IT'S TIME FOR COMBAT TRAINING! THE SITUATION: VILLAINS HAVE HIDDEN A NUCLEAR WEAPON IN A STRONGHOLD! THE HEROES MUST INFILTRATE AND EITHER APPREHEND THE VILLAINS OR SECURE THE WEAPON WITHIN FIFTEEN MINUTES!"

 

All Might drew lots from a box to determine the teams.

 

"TEAM A: IZUKU MIDORIYA AND OCHACO URARAKA! YOU WILL BE THE HEROES!"

 

Izuku turned to Uraraka, offering a polite smile. "It seems we'll be working together, Uraraka. I look forward to it."

 

"Yeah! Let's do our best!" she cheered.

 

"AND YOUR OPPONENTS..." All Might reached into the villain box. "TEAM D: KATSUKI BAKUGO AND TENYA IIDA!"

 

The atmosphere in the group instantly shifted.

 

Katsuki didn't cheer. He didn't say a word. He slowly turned his head, his crimson eyes locking onto Izuku with the intensity of a dying star. His fists clenched so tightly his leather gloves creaked.

 

Izuku met his gaze. The air between them seemed to grow heavy, the ambient pressure dropping as Izuku’s Quirk subconsciously reacted to the tension.

 

So, Izuku thought, his expression remaining perfectly serene. It's time.

 

 The Strategy

 

Team D (The Villains) was given five minutes to enter the building and set up their defenses.

 

Izuku and Uraraka stood outside the front entrance of the multi-story complex, waiting for the buzzer. Izuku had his eyes closed.

 

"So, Midoriya, what's the plan?" Uraraka asked, bouncing on her toes. "Bakugo seems really intense. And Iida is super fast. Should we sneak in? Try to find them before they find us?"

 

Izuku didn't open his eyes. He raised his bare hand, his fingers delicately tracing the empty air in front of him.

 

"There's no need to search," Izuku said softly.

 

"Huh?"

 

"I have already mapped the building's interior," Izuku explained. "A structure this size relies on a central HVAC—Heating, Ventilation, and Air Conditioning—system. By tapping into the air currents escaping the vents, I can feel the architectural layout. I can also feel the thermal displacement of two human bodies."

 

He pointed up to the fifth floor. "The bomb is in the north room on the fifth floor. Iida is pacing back and forth around it. His breathing is steady, but elevated. He's nervous."

 

Izuku lowered his hand, pointing at the main entrance directly in front of them. "Kacchan, however, is not with the bomb. He is waiting in the lobby. He intends to ambush us the moment we walk through the door."

 

Uraraka stared at him, her mouth agape. "You can... you can see all that? Just from the air?"

 

"The air touches everything, Uraraka," Izuku said, opening his eyes. "Here is the strategy. Kacchan is entirely focused on me. He won't let us pass. I will engage him. While I have him distracted, I will provide you with a direct route to the bomb room. Once there, you just need to tap the weapon."

 

"But how do I get past Bakugo without him noticing?" she asked.

 

Izuku smiled, a small, reassuring expression. "Leave that to me. You just need to hold your breath when I tell you to."

 

A loud buzzer echoed across the training grounds.

 

"HERO TEAM, YOU MAY ENTER!" All Might's voice rang over the intercom.

 

Izuku and Uraraka stepped through the main doors into the dimly lit lobby of the building. It was a maze of concrete pillars and shadowed corridors.

 

Total silence.

 

Three... two... one... Izuku counted in his head.

 

"DIE, DEKU!"

 

From behind a concrete pillar to their right, Katsuki Bakugo launched himself through the air. He didn't use a normal explosion. He used a massive, concussive blast from his gauntlets to propel himself forward at blistering speed, a right hook aimed directly at Izuku’s face, his palm sparking with a lethal ignition.

 

"Midoriya!" Uraraka screamed.

 

Izuku didn't flinch. He didn't even shift his stance.

 

As Katsuki’s fist closed within inches of Izuku’s face, Izuku casually raised his left hand, placing his open palm lightly against Katsuki’s wrist.

 

Izuku didn't push. He yielded.

 

Utilizing Baguazhang's core principle of redirection, Izuku used Katsuki’s own immense forward momentum against him. Izuku pivoted smoothly on his right heel, guiding Katsuki’s arm past his face. Simultaneously, Izuku created a micro-slick of frictionless air beneath Katsuki’s boots.

 

With zero friction to ground him, Katsuki’s momentum carried him wildly out of control. He flew past Izuku, spinning helplessly through the air, and slammed back-first into a concrete wall with a heavy thud.

 

"Gah!" Katsuki grunted, dropping to one knee. He looked up, his eyes burning with fury. "You bastard! Stop dodging!"

 

"You're relying too much on linear attacks, Kacchan," Izuku said, his voice echoing calmly in the lobby. "Your blasts make your trajectory entirely predictable."

 

In the monitor room, the class was watching the screens in stunned silence.

 

"He didn't even use his Quirk offensively," Kirishima gasped. "He just... slipped right past him. That's a pro-level martial arts throw!"

 

All Might gripped the console tightly. Incredible. He possesses absolute power, yet he relies on technique and redirection first. He's minimizing damage to the building and his opponent.

 

Back in the lobby, Katsuki slowly stood up. His pride was bleeding. He had trained for years. He had bled, sweated, and pushed his Quirk to its absolute limits, all to surpass the boy standing in front of him. But Izuku wasn't even breaking a sweat. He was looking at Katsuki not as a threat, but as an equation to be solved.

 

"I'm not playing your games, Deku," Katsuki growled. He raised his right arm, pointing his massive, grenade-shaped gauntlet directly at Izuku and Uraraka.

 

He reached his left hand over to the pin on the gauntlet.

 

"Bakugo, wait!" All Might's voice crackled frantically over the intercom. "Are you crazy?! A blast that size indoors will destroy the structural integrity of the building! You'll kill him!"

 

"He won't die if he dodges!" Katsuki roared.

 

"Uraraka," Izuku said softly, not taking his eyes off Katsuki. "Cover your ears."

 

Uraraka clamped her hands over her ears.

 

Katsuki pulled the pin.

 

The gauntlet, filled to the brim with highly concentrated, explosive nitroglycerin sweat, ignited. The chamber glowed a blinding, hellish orange.

 

In the monitor room, students screamed. All Might reached for the abort button.

 

But Izuku Midoriya was faster than a button press. Time seemed to slow down for him.

 

Combustion requires fuel, heat, and oxygen, Izuku analyzed in a fraction of a millisecond. He has provided the fuel and the heat. I simply deny the third variable.

 

As the explosion erupted from the gauntlet, expanding outward in a terrifying wave of fire and kinetic death, Izuku snapped his fingers.

 

He didn't just pull the oxygen away. He created an absolute, spherical vacuum around Katsuki and the expanding blast radius.

 

The results defied logic, but obeyed physics perfectly.

 

First, the sound. The roar of the explosion, which should have shattered the eardrums of everyone in the building and blown out the cameras, hit the wall of the vacuum and died instantly. Sound cannot travel through empty space. The monitor room went dead silent.

 

Second, the fire. The blinding inferno surging toward Izuku hit the oxygen-less void and instantly choked. It didn't blow back; it just vanished, collapsing into a pathetic, harmless puff of black smoke that dissipated harmlessly in the air.

 

Third, the kinetic force. Deprived of the rapid expansion of gases caused by combustion, the concussive shockwave died before it could even ripple Katsuki’s clothes.

 

Katsuki stood there, his arm extended, his gauntlet smoking.

 

There was no explosion. There was no destruction.

 

Katsuki stared at his gauntlet, his crimson eyes wide with an emotion bordering on despair. He had fired his ultimate move, a blast capable of leveling a city block. And Izuku had snuffed it out like a cheap candle, without taking a single step.

 

"I told you when we were seven, Kacchan," Izuku's voice broke the silence, soft but echoing with finality. "Combustion requires oxygen. Inside this building, I control every single molecule you breathe. Your Quirk belongs to me here."

 

Katsuki let out a scream of pure, visceral frustration and charged, abandoning his gauntlets, throwing a wild, desperate haymaker.

 

Izuku sighed. He raised his hand.

 

He didn't hit Katsuki. He didn't even touch him.

 

Izuku compressed the air around Katsuki’s body, solidifying the atmosphere into a dense, invisible pillar. He lifted the pillar into the air, carrying a struggling Katsuki with it, and slammed it upward against the ceiling of the lobby.

 

Katsuki was pinned flat against the concrete ceiling, fifteen feet in the air. He thrashed, cursed, and tried to ignite his sweat, but Izuku had created a micro-vacuum over his palms. He couldn't move. He couldn't blast. He was entirely, helplessly immobilized by empty air.

 

"Let me go! Fight me, you coward!" Katsuki screamed, thrashing against the invisible restraints.

 

"You are restrained, Kacchan," Izuku said politely, looking up at him. "Attempting to struggle will only exhaust you."

 

Izuku turned his back on the furious boy and looked at Uraraka, who was staring at the ceiling in absolute shock.

 

"Right," Izuku said, dusting off his hands. "Phase two. Uraraka, take a deep breath."

 

"Huh? Okay!" She inhaled deeply, puffing her cheeks out.

 

Izuku raised his hand. A sphere of compressed, solid air formed around Uraraka, enclosing her completely in a transparent bubble.

 

"Hey! What's going on?!" she mumbled, her voice muffled through the air shield.

 

Izuku pointed his other hand toward the massive, industrial ventilation grate on the wall of the lobby. He flicked his wrist. A razor-thin blade of vacuum pressure sheared the bolts off the grate, sending it clattering to the floor.

 

"Iida is on the fifth floor," Izuku explained, walking over to the vent. "Walking up the stairs would take two minutes, and we'd have to navigate the corridors. However, this ventilation shaft runs vertically up the building, intersecting directly with the bomb room."

 

Uraraka, floating inside her bubble, went pale as she realized what he was suggesting.

 

Izuku gently guided her bubble into the gaping maw of the ventilation shaft.

 

"The bubble will protect you from the sheet metal, and it contains enough oxygen for two minutes," Izuku said, offering a bright, reassuring smile. "It's going to be a bit fast. See you at the top."

 

Before she could protest, Izuku clapped his hands together.

 

Pneumatic Launch.

 

Izuku forced a massive, hyper-compressed volume of air into the bottom of the ventilation shaft.

 

FWOOSH!

 

Uraraka was fired up the shaft like a bullet in a pneumatic tube. She screamed (though nobody could hear her), shooting up through the floors at thirty miles per hour, safely cushioned by Izuku’s indestructible air bubble.

 

 The Victory

 

On the fifth floor, Tenya Iida paced nervously around the papier-mâché nuclear bomb.

 

"Bakugo has engaged them!" Iida muttered to himself, adjusting his villain mask. "But I must remain vigilant! Midoriya is a cunning tactician! I have removed all the items in this room so Uraraka cannot use her Zero Gravity! I am perfectly prepared!"

 

Iida struck a dramatic villain pose, laughing evilly. "Mwahahaha! Come, heroes! I will defend this payload with my—"

 

CLANG!

 

The massive metal grate of the room's ventilation shaft blew off its hinges, rocketing across the room and embedding itself in the far wall.

 

Iida jumped back in shock. "What in the name of villainy?!"

 

Out of the shaft shot a transparent bubble containing a very dizzy, very green-looking Ochaco Uraraka. The bubble hit the floor, bounced twice over Iida’s head, and landed squarely on top of the nuclear bomb.

 

With a soft pop, Izuku dissolved the air bubble from the lobby on the first floor.

 

Uraraka tumbled out, gasping for air, and flopped directly onto the bomb. Her hand slapped against the surface of the weapon.

 

"Secure..." she groaned, her head spinning.

 

Iida stood frozen, his hand still raised in his dramatic pose, staring at the girl who had just been violently expelled from the HVAC system directly onto the objective.

 

"HERO TEAM WINS!" All Might's voice blared over the speakers.

 

Down in the lobby, Izuku released his hold on the ceiling. Katsuki dropped to the floor, landing on his feet, but his legs gave out. He fell to his knees, panting, staring at the concrete floor.

 

He hadn't been beaten. He had been dismantled. Izuku hadn't even viewed him as an opponent; he had viewed him as a minor traffic delay on the way to the objective.

 

Izuku walked over to Katsuki, offering his hand.

 

"Good match, Kacchan," Izuku said, his voice entirely genuine, lacking any hint of mockery.

 

Katsuki looked at the offered hand. He didn't smack it away. He didn't yell. He just looked at it, his eyes wide and trembling. For the first time in his life, Katsuki Bakugo felt truly, utterly small.

 

He ignored the hand, stood up on his own, and walked silently out of the building.

 

 The Aftermath

 

When Izuku and Uraraka returned to the monitor room, the class parted for him like the Red Sea.

 

Nobody spoke. Even Momo Yaoyorozu, the class genius, was staring at Izuku with a look of profound apprehension.

 

"WELL!" All Might boomed, clapping his hands together, trying to dispel the heavy atmosphere in the room. "THAT WAS... AN INCREDIBLY EFFICIENT DISPLAY! CAN ANYONE TELL ME WHO THE MVP OF THIS MATCH WAS?!"

 

Momo raised her hand slowly. "It was Midoriya, sir."

 

"AND WHY IS THAT, YOUNG YAOYOROZU?!"

 

"Because," Momo analyzed, her eyes darting to Izuku, "he displayed absolute battlefield control. He neutralized a highly destructive threat without inflicting a single injury. He completely mitigated collateral damage to the stronghold. And he utilized the environment to secure the objective in less than three minutes without ever setting foot on the target floor."

 

She swallowed hard. "He essentially solved the scenario perfectly. It wasn't a fight. It was a mathematical equation."

 

All Might nodded slowly. She's right, he thought, looking at the green-haired boy who was politely apologizing to Uraraka for making her dizzy in the vents. He is perfect. Perhaps... too perfect. He has walled off his emotions entirely to control that Quirk.

 

"EXCELLENT ANALYSIS!" All Might cheered. "LET'S MOVE ON TO THE NEXT MATCH!"

 

As the class turned their attention back to the screens, Shoto Todoroki stood in the back of the room, his heterochromatic eyes locked onto Izuku.

 

He suffocated an explosion, Todoroki thought, clenching his left fist, feeling the heat of his fire Quirk bubbling under his skin. Fire is useless against him. If I fight him, I'll have to rely on ice. But... can you freeze someone who controls the air itself?

 

Izuku felt the cold gaze from across the room. He didn't turn around. He simply reached out with his senses, feeling the subtle drop in temperature radiating from Todoroki.
