What if deku looked up to best jeanist?

 The fabric of society is held together by a million invisible threads. 

Most people never notice them. They walk through life admiring the bold patterns, the bright colors, the sweeping designs of heroism and villainy that paint the modern world. They look at the towering figures of Pro Heroes and see titans of strength, pillars of peace, gods among men who solve problems with earth-shattering punches and blinding flashes of light. They see the spectacle. 

But Izuku Midoriya, even at four years old, did not look at the spectacle. He looked at the seams.

The glow of the computer monitor illuminated the dark room, casting a pale, bluish light over the boy’s wide, emerald eyes. He was sitting cross-legged in his rolling chair, rocking slightly back and forth. His mother, Inko, stood in the doorway, a gentle, fond smile tugging at the corners of her lips. It was past his bedtime, but Izuku had begged to watch the video just one more time. 

It wasn't an All Might video. Inko had bought him the All Might action figures, the All Might pajamas, and the All Might posters, assuming her son would naturally gravitate toward the Number One Hero like every other child his age. But while Izuku respected All Might, the hero who captured his absolute, undivided fascination was someone entirely different. 

"Izuku, sweetie," Inko murmured, stepping softly into the room. "This is the tenth time today. Your eyes are going to get stuck like that."

"Mom, look," Izuku whispered, pointing a small, chubby finger at the screen. "Look at how he does it."

Inko sighed fondly, coming to stand behind his chair, resting her hands on his shoulders as they watched the grainy internet footage play out. 

On the screen, a chaotic scene was unfolding. It was archival footage of a hostage situation in a downtown bank, filmed by a news helicopter hovering above. Three villains with terrifying, mutant-type Quirks had barricaded themselves inside, threatening to bring the building down. The police were cordoned off, completely helpless. Panic was a palpable, frantic energy radiating through the pixels. 

Then, he arrived. 

There was no booming laugh. There was no crater-inducing leap that shattered the pavement. There was only a tall, unnervingly slender man dressed head-to-toe in immaculate, reinforced denim. A high collar covered his mouth and nose, his blonde hair was swept to the side with razor-sharp precision, and his posture was so perfectly straight it seemed as though a steel rod ran down his spine. 

Tsunagu Hakamada. The Fiber Hero: Best Jeanist.

The villains, enraged by his silent arrival, charged. One breathed a torrent of fire; another swung a fist the size of a boulder. To a four-year-old, it should have been terrifying. But Izuku wasn't afraid. He leaned closer to the screen, his breath hitching.

Jeanist didn’t flinch. He didn’t dodge. He simply raised his hands, his fingers moving in a fluid, mesmerizing rhythm, like a maestro conducting a symphony only he could hear. 

Zip. 

Thick cables of carbon-fiber thread shot out from the cuffs of his sleeves. In less than a second, the threads danced through the air, weaving between the fire, wrapping around the boulder-sized fist, moving with an eerie, beautiful sentience. 

Pull.

Jeanist flicked his wrists. The villain with the boulder fist was suddenly jerked off balance, the threads binding his arms to his torso, wrapping him in an inescapable cocoon. The villain breathing fire found his jaw clamped shut by an impossibly tight weave of denim fibers, his flames sputtering out harmlessly through his nose. The third villain tried to run, but a single thread whipped out, snaring his ankle and leaving him dangling upside down from a streetlamp.

The entire altercation took less than six seconds. 

There were no explosions. No shattered glass. No collateral damage. The street was as pristine as it had been before the villains arrived. The hostages were safe, the villains were completely immobilized without a single drop of blood spilled, and Best Jeanist hadn't even wrinkled his shirt.

On the screen, a reporter rushed up to the hero, thrusting a microphone into his face. "Best Jeanist! What an incredible display! Do you have anything to say to the viewers at home?"

Jeanist looked directly into the camera, his visible eye calm, calculating, and cold. "True heroism is not about how hard you can strike down evil. It is about how elegantly you can restrain it. A hero must be the needle that mends the frayed edges of society. Stay sharp, stay disciplined, and never lose your composure."

The video ended, freezing on Jeanist’s impeccably styled hair and high denim collar. 

Izuku let out a long, shaky exhale. His eyes were shining with a profound, quiet intensity that Inko couldn't quite understand. Other boys wanted to smash villains into the dirt. They wanted to roar and flex their muscles. Izuku wanted to control the chaos. He wanted to mend the frayed edges.

"He's so cool," Izuku breathed, his voice barely above a whisper. "He didn't hurt them. He just... stopped them. Everyone is safe, and nothing is broken."

"He is very impressive, Izuku," Inko said, smoothing his wild, curly green hair. "But it's time for bed. You have a big day tomorrow. We're going to the doctor to see what your Quirk is going to be!"

Izuku looked up at her, a wide, genuine smile spreading across his face. "Do you think I'll get a Quirk like Jeanist's, Mom? Do you think I'll be able to control threads?"

"Maybe," Inko chuckled. "With my telekinesis and your father's fire-breathing, who knows what you'll get? Maybe you'll be able to pull hot threads! Now, come on. Off to bed."

Izuku crawled into bed, his mind racing. He didn't dream of flying, or super strength, or lasers. He dreamed of strings. He dreamed of holding the world together with perfectly tied knots, of stopping bad guys with a simple, elegant flick of his wrist. He was going to be a hero who never lost his composure. 

The sterile smell of the doctor's office was something Izuku would never forget. It smelled like rubbing alcohol, old magazines, and disappointment.

He sat on the examining table, his small legs dangling over the edge, kicking nervously. Inko sat in the chair beside him, her hands wrung together in her lap. The doctor, an older man with a bushy mustache and a pair of goggles resting on his forehead, was staring at an X-ray pinned to the glowing light board. 

The silence stretched on, thick and suffocating. 

"You should probably give it up," the doctor finally said, his tone blunt, carrying the practiced apathy of a man who delivered bad news for a living. 

Inko gasped, her hand flying to her mouth. "Give... give it up? But, Doctor, isn't there some mistake? The other kids in his kindergarten class have all manifested their Quirks by now. Izuku is just a late bloomer, right?"

The doctor sighed, tapping the X-ray with a pen. "I'm sorry, Mrs. Midoriya. But the science is quite settled on this matter. You see this joint here? The pinky toe."

Izuku stared at the skeletal image of his own foot. 

"When Quirks first began appearing, researchers found a correlation between the absence of a Quirk and the presence of two joints in the pinky toe. It represents an older, unevolved stage of human anatomy. People with Quirks only have one joint. Izuku here has two." The doctor turned in his chair, looking directly at the four-year-old boy. "You're Quirkless, kid. You're never going to develop a power."

The room seemed to shrink. The air grew cold. 

Inko burst into tears, dropping to her knees beside the examination table and burying her face in Izuku's chest. "I'm sorry, Izuku! I'm so sorry! I'm so, so sorry!" she sobbed, apologizing as if she had committed a terrible crime, as if she had stolen his future with her own two hands.

If Izuku had idolized All Might, this would have been the moment his world shattered. All Might was a symbol of invincible power. To be like All Might, you needed a power that could crush mountains and weather storms. A Quirkless boy could never be a symbol of peace. A Quirkless boy could never punch a villain into the stratosphere. If he had worshipped strength, he would have cried.

But Izuku didn't worship strength. He worshipped control. 

"A hero must be the needle that mends the frayed edges of society. Stay sharp, stay disciplined, and never lose your composure."

Jeanist's words echoed in his mind, clear as a ringing bell. 

Izuku looked down at his mother, feeling the wetness of her tears soaking into his t-shirt. He looked at his own hands. They were small, unblemished, completely ordinary. They couldn't produce explosions like Katsuki's. They couldn't pull small objects like his mother's. They were just hands. 

But Jeanist used threads. Jeanist used tools. If a Quirk was just a tool, and Izuku didn't have one built into his body... then he would just have to make his own. 

Slowly, deliberately, Izuku placed his small hands on his mother's shaking shoulders. He didn't cry. His emerald eyes were dry, unblinking, and suddenly possessed an analytical depth that was entirely too old for a four-year-old.

"Mom," Izuku said softly. His voice didn't waver. 

Inko looked up, her eyes red and puffy. "Y-Yes, sweetie?"

"Please don't cry. It's okay," Izuku said, his voice terrifyingly calm. "But on the way home... can we stop at the craft store?"

Inko blinked, confused by his lack of tears, confused by the sudden, bizarre request. "The... the craft store? Why?"

Izuku looked at his hands again, flexing his small fingers, testing their joints, feeling the tendons pull beneath his skin. 

"I need some thick yarn," Izuku said, his voice flat, resolute. "And some knitting needles. I need to learn how to tie knots."

Ten years is a long time. It is enough time for a caterpillar to become a butterfly, for a sapling to become a tree, and for a Quirkless child to learn exactly how cruel the world can be. 

But Izuku Midoriya did not let the world break him. He simply wove himself a protective layer.

Aldera Junior High was a loud, chaotic place, filled with teenagers who were drunk on the hormones of puberty and the arrogant confidence that came with developing flashy Quirks. The classroom was a cacophony of shouting, laughter, and small, unauthorized uses of powers. A boy in the back was stretching his neck to look at a girl's phone; another was generating small sparks from his fingertips. 

Sitting in the middle row, perfectly still, was a fourteen-year-old Izuku Midoriya. 

He was a stark contrast to everything around him. While the other male students wore their black gakuran uniforms slouched, unbuttoned, or wrinkled, Izuku's was immaculate. It was ironed with knife-edge creases. The collar of his uniform was pulled up uncomfortably high, buttoned to the very top so that it brushed against his jawline, obscuring his neck completely. His posture was rigid, his spine perfectly straight, his hands folded neatly on his desk. He breathed in slow, measured counts—in through the nose for four seconds, hold for two, out through the mouth for six. 

Composure.

On his desk sat a thick, leather-bound notebook. It didn't read Hero Analysis for the Future. It read: Applied Restraint Mechanics & Tensile Material Analysis: Vol. 13. 

Inside, the pages were not filled with drawings of heroes flexing their muscles. They were filled with complex diagrams of villain physiologies, calculations on the breaking strain of various industrial cables, blueprints for grappling hooks, and psychological profiles on how to de-escalate hostage situations. There were meticulously sketched diagrams of the Constrictor Knot, the Bowline on a Bight, and the Zeppelin Bend. 

"Alright, settle down, everyone!" the homeroom teacher shouted, slamming a stack of papers onto his podium. "You're all third-years now. It's time to start thinking seriously about your futures! I'm passing out printouts for your desired career paths..."

The teacher paused, a smirk crossing his face as he grabbed the stack of papers and tossed them carelessly into the air. 

"But who am I kidding? You all want to be heroes, right?!"

The classroom erupted into cheers. Students leaped out of their desks, showing off their Quirks in a blatant violation of school rules. Arms elongated, eyes glowing, small bursts of water shooting into the air. 

"Yes, yes, you all have wonderful Quirks," the teacher sighed, though he looked amused. "But remember, using your powers in school is against the rules!"

"Sensei! Don't lump me in with these losers!"

The loud, arrogant voice cut through the noise like a chainsaw. From the front of the classroom, Katsuki Bakugo kicked his feet up onto his desk, leaning back with a smug, feral grin on his face. His ash-blonde hair spiked in every direction, mirroring his explosive personality. 

"I'm not gonna be stuck at the bottom with the rest of these rejects," Bakugo sneered, small explosions popping like firecrackers in the palms of his hands. "I'm the only one here who's got what it takes to make it to the big leagues. I aced all the mock tests, and I'm the only one from this crappy junior high who's going to U.A. High School!"

Whispers broke out across the room. U.A.? The national school? The acceptance rate is insanely low! 

"That's right," Bakugo gloated, standing up and puffing out his chest. "I'm going to surpass All Might and become the top-ranking hero! My name will be carved in history!"

"Oh, right," the teacher said, glancing down at a clipboard. "Midoriya, didn't you also apply for U.A.?"

The classroom froze. The silence was instantaneous and absolute. Then, a heartbeat later, the entire class erupted into hysterical laughter. 

"Midoriya?! No way!"

"You can't get into the hero course just by studying, man!"

"He doesn't even have a Quirk! What's he gonna do, polite a villain to death?"

Izuku didn't flinch. He didn't shrink down in his seat. He didn't stutter, and he certainly didn't cry. He simply blinked his emerald eyes, picked up a mechanical pencil, and continued taking notes on the shear strength of Kevlar blends. 

If Katsuki's explosions generate an average heat of 1,200 degrees Celsius, Izuku thought, the graphite scratching smoothly across the paper, a standard Nomex fiber suit would degrade within four seconds of sustained contact. I'd need a multi-layered silica weave to withstand a point-blank blast without losing structural integrity.

"Deku!"

A shadow fell over Izuku's desk. Bakugo was standing there, his face twisted into a snarl of absolute fury. The nickname "Deku" meant "useless," a cruel moniker Bakugo had given him years ago. In the past, Bakugo used it to make Izuku cry. Now, he used it because Izuku's lack of reaction infuriated him to his core. 

Bakugo slammed his hand down onto Izuku's desk. A sharp crack echoed through the room as an explosion detonated against the wood, instantly carbonizing the surface and catching the edge of Izuku's notebook on fire. 

"Listen to me, you Quirkless wannabe," Bakugo hissed, smoke curling from his palm. "You're worse than the rest of these rejects. You're completely unequipped. You think you can stand in the same ring as me? You think U.A. is gonna let a fragile little doll like you into their halls? You'll die in the entrance exam."

Izuku slowly lifted his head. His eyes met Bakugo's furious crimson gaze. There was no fear in Izuku's eyes. There was only a cold, clinical appraisal. 

"Katsuki," Izuku said, his voice smooth, quiet, and perfectly polite. "Your blast radius was exactly twenty-two centimeters. You damaged school property and jeopardized the structural integrity of my desk. Furthermore, you failed to account for the proximity of the window curtains. If the wind had drafted, you could have started a localized structural fire. It was a sloppy, inefficient use of energy."

Bakugo's eye twitched violently. A vein throbbed in his forehead. 

If Izuku had cowered, Bakugo would have laughed. If Izuku had yelled back, Bakugo would have hit him. But this... this unnerving, emotionless critique, delivered by a boy who was supposed to be completely beneath him, drove Bakugo utterly insane. It was like screaming at a brick wall that kindly corrected your grammar.

"Shut up!" Bakugo roared, grabbing Izuku by the collar of his pristine uniform, pulling him half out of his chair. "I don't need your damn analysis, Deku! I'm telling you to drop out of the U.A. exam! You're an embarrassment!"

Izuku stared at the hand gripping his collar. He analyzed the grip. Bakugo's thumb was improperly placed, relying entirely on bicep strength rather than leverage. With a simple, two-fingered strike to the radial nerve in Bakugo's forearm, Izuku knew he could force the blonde to release him in 0.8 seconds. He had spent the last ten years studying jujutsu, aikido, and anatomy, compensating for his lack of a Quirk with absolute, terrifying precision. 

But striking Bakugo would cause a scene. It would escalate the violence. It would be... inelegant. 

Instead, Izuku reached up and gently, firmly grasped Bakugo's wrist. He didn't squeeze. He just held it, a silent warning. 

"U.A. removed the rule barring Quirkless individuals from applying two years ago, Katsuki," Izuku said softly, his voice never rising in volume. "I am legally permitted to take the exam. If I am as unequipped as you say, the exam will filter me out. But screaming at me in a classroom will not change my application status. It only makes you look undisciplined."

Bakugo stared at him, breathing heavily, his teeth bared like a rabid dog. He wanted to blow Izuku's face off. But looking into those dead, calm green eyes, Bakugo felt a strange, sickening twist in his gut. It wasn't fear. It was an uncanny valley sensation. The boy in front of him wasn't acting human. He was acting like a machine. 

"Tch," Bakugo spat, violently shoving Izuku backward. Izuku caught his balance instantly, smoothly adjusting his uniform and smoothing out the wrinkles Bakugo had caused. 

"You're a creep, Deku," Bakugo sneered, grabbing Izuku's scorched notebook from the desk. "You want to be a hero so bad? I've got a time-saving idea for you." 

Bakugo tossed the notebook out the open window. It plummeted three stories down. 

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

The classroom went dead silent. The other students grimaced. Even for Bakugo, telling someone to kill themselves was crossing a massive line. They waited for Izuku's reaction. Surely, this would break his icy exterior. 

Izuku stood up from his desk. He brushed a small speck of ash off his sleeve. He looked Bakugo directly in the eye, his expression completely blank. 

"Encouraging suicide is a felony offense under Article 202 of the Penal Code, Katsuki," Izuku stated calmly. "If I were to follow your advice, you would be charged with instigation of suicide. A felony conviction permanently disqualifies an individual from obtaining a Pro Hero license. I highly recommend you control your temper before your lack of verbal restraint ruins your career."

With that, Izuku turned, slung his heavy reinforced backpack over his shoulder, and walked toward the classroom door. He didn't look back. 

Bakugo stood frozen in the middle of the room, his fists trembling with rage, his jaw slack. He had tried to crush an ant, and the ant had just read him his Miranda rights. 

"God, I hate him," Bakugo whispered vehemently to himself, sparks hissing uselessly from his palms. 

The afternoon sun cast long, golden shadows across the pavement as Izuku walked away from Aldera Junior High. 

He found his notebook in a small koi pond outside the school building. The leather cover was scorched, and the pages were soaked through, the ink bleeding into illegible smudges. Izuku sighed quietly. It was annoying, but not catastrophic. He had a photographic memory when it came to his restraint techniques. He could rewrite Volume 13 from scratch in a weekend. 

He carefully shook off the excess water, placed the ruined notebook into a waterproof sleeve inside his bag, and began the long walk home. 

As he walked, his hands were not idle. From the side pocket of his thick canvas backpack, Izuku withdrew a length of heavy-duty climbing rope. It was a half-inch thick, made of braided nylon, capable of bearing over two thousand pounds of weight. 

His fingers moved with blinding speed and unconscious muscle memory. Loop, twist, pull. A perfect Figure-Eight knot appeared. Undo, cross, under, over. A pristine Clove Hitch. Undo, wrap, tuck. A Timber Hitch. 

He tied and untied the knots repeatedly as he walked, his eyes staring straight ahead, his mind completely detached from the physical action. He had been doing this every single day for ten years. While other kids played video games, Izuku tied knots. While other kids practiced their Quirks, Izuku studied knot-tying manuals until his fingers bled and calloused. He could tie a restraining knot blindfolded, underwater, hanging upside down. 

His mother had worried, of course. She thought his obsession with threads, ropes, and bindings was unhealthy. But Izuku knew the truth. 

He lived in a world of monsters. Men who could turn into giant sharks, women who could level city blocks with a thought, criminals whose bodies were forged of steel or wreathed in fire. To stand among them without a Quirk was suicide—unless you knew exactly how to bind them. 

Best Jeanist is currently ranked Number Four, Izuku thought, a small, genuine smile finally ghosting across his face as he tied a complex Monkey's Fist knot. His approval rating has skyrocketed because he minimizes property damage. The public is getting tired of brawlers like Endeavor destroying infrastructure. The modern era of heroism requires surgical precision. It requires... elegance.

Izuku adjusted the high collar of his uniform, making sure it covered his neck. He liked the high collar. It felt like armor. It kept the world out, and it kept his composure locked in. 

His route home took him under a wide, concrete overpass. It was a shortcut, usually quiet and empty. The shadows beneath the bridge were deep and cool, offering a brief respite from the afternoon heat. 

Izuku was halfway through the tunnel, currently practicing a modified Handcuff Knot, when he heard it. 

Gurgle. Squelch. Schhhlluuck.

It sounded like thick, wet mud being forced through a drainpipe. Izuku stopped walking. His fingers froze on the rope. The hairs on the back of his neck stood up, a primal instinct warning him of immediate, catastrophic danger. 

He didn't panic. He didn't scream. He simply turned around, his posture remaining perfectly straight, his eyes scanning the environment, looking for the source of the anomaly. 

Behind him, from the manhole cover he had just walked past, a horrific mass of dark green slime was oozing upward. It poured out of the grate like an inverted waterfall, rising and expanding until it formed a towering, gelatinous mound of filth. It smelled of raw sewage and rotting garbage. Two massive, bulbous eyes floated near the top of the mass, along with a wide, jagged mouth filled with crooked teeth.

"Well, well, well," the Sludge Villain gurgled, its voice wet and guttural. "A medium-sized meat suit. Perfect timing. I need a place to hide. Don't worry, kid. It'll only hurt for about forty-five seconds... and then it'll all be over."

The villain lunged. 

A massive tendril of thick slime shot forward, aiming directly for Izuku's face. 

Most people would have frozen. Most people would have thrown their hands up, squeezed their eyes shut, and screamed for help. 

Izuku's heart rate spiked, but his mind went completely, terrifyingly blank. The world slowed down. 

Threat Assessment: Mutant-type or Emitter-type Quirk. Fluid composition. Highly viscous. Corrosive? Unknown. Weak points: Eyes, internal mouth structure. Physical strikes will be completely ineffective. Blunt force will be absorbed. Sharp force will pass through without permanent damage.

The slime tendril was less than two feet away. 

Izuku didn't run. Running was inefficient. He dropped his stance, bending his knees, and his hands moved with the speed of a striking viper. 

He whipped the heavy climbing rope he was holding upward. In a fraction of a second, he looped the rope over his own ears and bit down hard on the center of the cord, creating a makeshift, tightly tensioned barrier across the lower half of his face. 

SPLAT.

The sludge slammed into Izuku, enveloping his head and shoulders. The impact knocked him backward, his reinforced backpack taking the brunt of the fall as he hit the concrete. 

"Gotcha!" the villain laughed, forcing the slime down into Izuku's nose and mouth. "Just let me in, kid! Let me take over!"

But the villain couldn't get in. 

Izuku lay on the ground, his eyes wide open, staring up through the murky green sludge. The villain was trying to force the slime down his throat to suffocate him, but the thick nylon rope Izuku had clamped in his teeth and wrapped around his head was acting as a physical barricade. The slime pressed against the rope, but the nylon was too thick, the tension too tight. It bought Izuku an air pocket—a tiny, precious pocket of oxygen. 

He's trying to enter my respiratory system to drown me and pilot my nervous system, Izuku analyzed, the sludge pressing heavily against his eyes. I cannot out-wrestle a fluid. I need to disrupt his central mass.

Izuku didn't flail his arms. He didn't claw uselessly at the slime. He calmly reached into the side pockets of his cargo pants. 

His fingers closed around two wooden spools. Wound tightly around each spool was fifty feet of high-tensile steel wire—the kind used for garroting or slicing through heavy machinery. 

Izuku flicked his wrists. The spools shot out of his hands, unraveling rapidly. He caught the loose ends of the wires in his fingers. 

If he is a fluid, Izuku thought, his lungs beginning to burn as the air pocket slowly shrank, then he is subject to the laws of surface tension and displacement.

Izuku brought his hands together, crossing the steel wires, and then violently whipped his arms outward in a massive arc. 

Schhhnnk!

The steel wires sliced cleanly through the gelatinous mass of the villain. They didn't cause pain—the villain had no solid pain receptors—but they severely disrupted his structural integrity. The slime split into three separate sections for a brief moment, forcing the villain to retract the sludge from Izuku's face to pull himself back together. 

Izuku gasped, pulling in a massive breath of fresh air as the slime retreated from his nose. He rolled backward, springing to his feet and creating distance. 

"You little brat!" the Sludge Villain roared, the three pieces of slime reforming into a towering mass. The villain's eyes narrowed, glaring at the boy. "What the hell was that? You got a wire Quirk or something? Whatever! I'll just crush you!"

The villain reared back, preparing to drop its entire mass onto Izuku like a tidal wave. 

Izuku stood his ground. He spat the climbing rope out of his mouth. He gripped the steel wires, calculating the exact angle he would need to slice the villain's eyes—the only solid organs visible. He knew he couldn't win this fight. He was outmatched. But he wasn't going to die panicking. He was going to die with composure. 

He braced his legs, ready to throw the wires. 

Suddenly, the manhole cover behind the villain exploded upward, flying into the air and clattering loudly against the concrete ceiling of the tunnel. 

"HAVE NO FEAR, YOU ARE SAFE!" 

A voice boomed through the tunnel. It was a voice that Izuku recognized instantly. It was a voice that every single person in Japan recognized. It was deep, resonant, and echoed with absolute, unquestionable power. 

A massive shadow stepped out of the sewer drain. 

"BECAUSE I AM HERE!"

The Sludge Villain froze, its bulbous eyes widening in absolute terror. "A-All Might?!" 

The Number One Hero stood in the tunnel, his gigantic, muscular frame practically blocking out the light. He was wearing his classic white t-shirt and cargo pants, a grocery bag clutched in one hand. Even out of his hero costume, he radiated an aura of invincible strength. 

"TEXAS..." All Might pulled his right arm back. The air around his fist seemed to distort, groaning under the immense pressure of his coiled muscles. "...SMASH!"

All Might threw the punch. 

He didn't hit the villain. He didn't need to. The sheer force of the air pressure generated by the punch created a localized hurricane inside the tunnel. The wind howled, a concussive shockwave that ripped the breath from Izuku's lungs. 

The Sludge Villain was obliterated. The wind caught the fluid mass and violently scattered it across the walls, the ceiling, and the floor, tearing the villain apart on a molecular level. 

Izuku dug his heels into the concrete, crossing his arms over his face as the gale-force winds threatened to blow him away. His steel wires whipped wildly in the air. 

Then, just as quickly as it had started, the wind died down. 

Silence descended on the tunnel, broken only by the soft, wet plops of slime dropping from the ceiling. 

All Might stood up straight, letting out a booming laugh. He pulled two empty plastic soda bottles from his grocery bag and began rapidly scooping up the scattered pieces of the villain. 

"HA HA HA! APOLOGIES, YOUNG MAN!" All Might boomed, capping the bottles tightly. "I DID NOT MEAN TO GET YOU CAUGHT UP IN MY JUSTICE! THIS FIEND ESCAPED ME EARLIER, BUT THANKS TO YOU HOLDING OUT, I WAS ABLE TO TRACK HIM DOWN! EXCELLENT WORK!"

Izuku stood completely still. 

He looked at All Might. He looked at the crater in the concrete caused by the wind pressure. He looked at the slime splattered across the entire tunnel. It would take a hazmat team weeks to clean this up. 

Izuku reached up, meticulously adjusting his high collar, smoothing out the wrinkles in his jacket. He coiled his steel wires back onto their wooden spools, slipping them neatly into his pockets. He picked up his climbing rope from the ground, tying it back into a neat coil. 

All Might turned to the boy, expecting what he always expected. He expected awe. He expected stars in the boy's eyes. He expected a frantic request for an autograph. 

Instead, the green-haired boy simply bowed, a perfect, ninety-degree angle. 

"Thank you for your assistance, All Might-san," Izuku said, his voice terrifyingly calm, completely devoid of the adrenaline rush that should have been coursing through his veins. "However, your application of force was highly inefficient. By using a wind-pressure attack in a confined cylindrical space, you risked a ricochet effect that could have severely injured me with debris. Furthermore, completely atomizing the villain makes containment difficult and increases the risk of him reforming if you missed a piece."

All Might froze. The Number One Hero blinked, utterly utterly bewildered. 

"Next time," Izuku continued smoothly, looking up at the towering giant, "I would recommend a targeted strike to the villain's eyes to induce shock, followed by an immediate vacuum seal. It would save time and minimize collateral damage."

Izuku bowed again. "Have a good afternoon."

Izuku turned around and began walking out of the tunnel, his posture perfect, his breathing slow and measured. 

All Might stood in the tunnel, holding the two bottles of slime, staring at the back of the fourteen-year-old boy. The Number One Hero, the Symbol of Peace, the man who had faced down gods and demons... was completely speechless. 

What... All Might thought, a bead of sweat dropping down his temple. What is up with that kid?!

Izuku walked into the sunlight, his mind already recalculating the tensile strength of his wires. He had survived. He had kept his composure. He was one step closer to becoming a hero. 

The threads of his destiny had just collided with the Number One Hero, but Izuku Midoriya had no intention of becoming the next All Might. 

He was going to weave his own path.

The tunnel was quiet, save for the rhythmic, echoing footsteps of Izuku Midoriya walking away from the Number One Hero. 

He was already mentally cataloging the tensile stress his steel wires had endured. Sludge, by its nature, offered little resistance, but the rapid deployment and retraction mechanisms he had built into his wooden spools needed recalibration. The friction coefficient was slightly off. If he were to face a villain with a hardened carapace, the current gauge of the wire might snap. He needed to look into carbon-nanotube weaving. Best Jeanist used carbon-fiber threads for high-threat targets; perhaps Izuku could source something similar, though the cost would be exorbitant on a junior high student’s allowance.

Behind him, All Might stood frozen, still processing the clinical, devastatingly polite critique delivered by a middle schooler. 

"W-Wait, young man!" All Might called out, taking a step forward. "I appreciate your... ah... feedback, but—"

Izuku never heard the rest of the sentence. 

It was interrupted by a sickening, wet thud, followed by an explosive hiss of escaping steam. 

Izuku stopped. He didn't jump, and he didn't gasp. He simply pivoted on his heel, his posture perfectly erect, his emerald eyes scanning the space he had just vacated. 

The towering, invincible figure of All Might was gone. In his place, enveloped in a thick cloud of white vapor, stood a skeletal, emaciated man. His clothes hung off him like sails on a dead ship. His cheekbones protruded sharply beneath hollow, sunken eyes. He was coughing violently, a thick spray of blood splattering against the concrete floor. 

At the man's feet, the two plastic soda bottles containing the Sludge Villain had rolled out of a discarded grocery bag. 

Most people—especially a devoted hero fanboy—would have panicked. They would have screamed, assuming an imposter had attacked All Might, or they would have suffered a total psychological breakdown at the sight of their invincible idol reduced to a coughing, bleeding corpse of a man. 

Izuku did none of those things. His mind, trained for a decade to compartmentalize fear and prioritize control, immediately went into diagnostic mode. 

Massive instantaneous loss of muscle mass, Izuku observed, his eyes tracking the man's shuddering breaths. Transformation Quirk? Unlikely. All Might has been recorded in the public eye for hours at a time without shifting. The steam suggests a rapid expulsion of cellular energy. The blood is dark—pulmonary origin. He is holding his left side. The way his shirt hangs indicates a significant concavity in the abdominal wall. He's missing organs.

Izuku walked back toward the man, his footsteps calm and deliberate. 

The skeletal man looked up, his hollow blue eyes wide with panic. He frantically waved his oversized hands, wiping blood from his chin. "W-Wait! It's not what you think! I am... I am All Might! I swear! It's like... you know how guys at the pool suck in their gut to look tougher? It's like that!"

Izuku stopped two feet away. He stared at the man, unblinking. 

"A muscular expansion Quirk coupled with extreme adrenaline manipulation," Izuku stated softly, his voice echoing slightly in the tunnel. "Fascinating. But the blood and the physical deterioration are not side effects of your Quirk, All Might-san. They are the result of catastrophic trauma."

All Might stopped waving his hands. The frantic energy drained from him, leaving only a bone-deep exhaustion. He stared at the fourteen-year-old boy, utterly unnerved by the lack of emotion in the kid's voice. 

"You're... you're a very perceptive kid," All Might sighed, sliding down the curved wall of the tunnel until he was sitting on the concrete. He lifted his baggy shirt, revealing a massive, terrifying network of purple and red scar tissue radiating from a central crater on his left side. It looked like a localized meteor strike on human flesh. 

Izuku’s eyes analyzed the scar. Five years old, judging by the keloid formation. A piercing attack combined with immense thermal or concussive force. It corresponds to his drop in public appearances half a decade ago. 

"An injury I got from an enemy attack five years ago," All Might rasped, confirming Izuku's silent hypothesis. "Half my respiratory organs were destroyed. I lost my entire stomach. I've had repeated surgeries, but I'm wasting away. I can only do hero work for about three hours a day now."

"The Toxic Chainsaw incident?" Izuku asked politely. 

"No," All Might shook his head. "That punk couldn't scratch me. This fight was kept out of the papers. The public can't know. The Symbol of Peace must be a flawless, invincible idol. If the villains knew I was this weak, society would collapse. I smile to show the pressure of heroes, and to trick the fear inside myself." 

All Might looked at the boy, expecting to see a shattered illusion. He expected tears. He expected the kid to look devastated. 

Izuku simply nodded, pulling out a small notepad from his pocket—a spare, since his main one was ruined. He clicked a pen and jotted down a few lines. 

"Your dedication to the psychological maintenance of the public is admirable, All Might-san," Izuku said, his tone conversational, as if they were discussing the weather. "However, operating on a three-hour limit with compromised respiratory function is highly inefficient and dangerous. You are relying entirely on overwhelming physical force to compensate for your decaying stamina. It explains your sloppy execution with the wind pressure earlier. You were rushing."

All Might choked on a mouthful of blood. He coughed violently, wiping his mouth with the back of his hand. "Kid... do you have any filter?"

"I apologize if my analysis offends you," Izuku said, bowing his head slightly. "I merely prefer to deal in empirical data rather than sentiment. Which brings me to a question I would like your data on."

All Might sighed, resting his head against the concrete. "Go ahead. Ask."

Izuku stood straight, his hands clasped neatly behind his back. The shadows of the tunnel framed him perfectly, a small, immaculately dressed boy standing before a broken god. 

"I do not possess a Quirk," Izuku stated calmly. "However, I have spent the last ten years studying restraint tactics, tensile physics, and human anatomy. I believe that pure strength is not the only metric of heroism. Best Jeanist, for example, operates entirely on control and precision. My question is this: Can a Quirkless individual, armed with absolute environmental control, psychological discipline, and tactical equipment, become a Pro Hero?"

All Might looked at the boy. He really looked at him. 

He saw the high collar, the rigid posture, the cold, calculating emerald eyes. He remembered how the boy had calmly deployed steel wires against a fluid villain instead of panicking. The kid was smart. Terrifyingly smart. But All Might knew the reality of the world. He knew the monsters that lurked in the dark. He knew the monster that had given him this scar. 

Threads and tactics wouldn't stop a Nomu. They wouldn't stop Him. 

"No," All Might said softly. His voice was heavy with sorrow, but firm with conviction. "I don't think you can."

Izuku didn't flinch. 

"Pro heroes are always putting their lives on the line," All Might continued, gesturing to his ruined stomach. "Villains out there have power that defies logic. Power that shatters concrete and melts steel. A tactical mind is good, yes. But without the power to back it up, one mistake means you die. If you want to help people with your mind, become a police officer. They get mocked, but it's a fine profession. It's not bad to dream, kid. But you have to make sure your dreams are realistic."

Silence stretched between them. 

All Might waited for the boy to cry. It was the hardest part of the job, shattering a child's dream. It always hurt. 

Izuku closed his notepad. He slid the pen into his pocket. He looked at All Might's scar, then up at his hollow eyes. 

"I see," Izuku said calmly. "Your assessment is based entirely on the paradigm of physical brawling. You operate under the assumption that a hero must physically clash with a villain's power to defeat it. You believe in the spectacle of force."

All Might frowned, confused by the boy's total lack of emotional devastation. "Kid, I'm just telling you the truth—"

"I accept your hypothesis based on your own lived experiences, All Might-san," Izuku interrupted smoothly, bowing deeply. "However, I respectfully disagree with your conclusion. If the current methodology of heroism requires power I do not possess, I will simply have to engineer a better methodology. One that relies on unravelling the villain before the clash ever happens."

Izuku straightened his collar. "Thank you for your time, and for saving me earlier. Please seek immediate medical attention for your hemoptysis. Relying on a depleted adrenaline cycle will only accelerate your cellular decay."

Izuku turned and walked out of the tunnel. 

All Might sat there, completely dumbfounded. He had just crushed a Quirkless kid's dream, and the kid had basically told him his data was flawed and walked away without shedding a single tear. 

"What... an incredibly strange boy," All Might muttered. He sighed, rubbing his face, trying to gather the energy to stand up. He reached blindly for the grocery bag. "Well, I better get this sludge guy to the police station before my time..."

His hand brushed against the plastic bag. It was flat. 

All Might looked down. The two plastic soda bottles were gone. 

He froze. His mind flashed back to the moment he had deflated. The sudden agony, the coughing fit, the explosive release of steam. He had dropped the bags. And just before the boy had started his psychoanalysis... there had been a slight rumble overhead. A truck passing over the bridge. A vibration. 

All Might scrambled to his hands and knees, ignoring the agonizing pain in his chest. He looked frantically around the tunnel floor. Nothing. 

"No... no, no, no!" All Might gasped. He must have dropped them. The bottles must have rolled out of the bag and into the drainage grates during his coughing fit. The villain was loose. 

And All Might was completely out of time. 

Izuku Midoriya walked down the bustling streets of Tatoin Shopping District, his mind a whirlwind of equations and anatomical diagrams. 

He was not depressed. He was not crushed by All Might's words. If anything, the encounter had validated his personal philosophy. All Might, the pinnacle of the "brawler" archetype, was secretly dying. His reliance on overwhelming force had resulted in catastrophic bodily failure. It was the ultimate proof that brute strength was an unsustainable model for long-term peace. 

Best Jeanist has been in the top ten for eight consecutive years without sustaining a single life-threatening injury, Izuku reasoned, stepping neatly around a group of chattering pedestrians. He maintains distance. He uses external fibers. He doesn't absorb impact; he redirects it. All Might's model is heroic, but fundamentally flawed. I will follow the threads, not the fists.

Izuku paused at a crosswalk. He pulled out a small piece of nylon cord from his pocket and absently began tying a complex Carrick Bend, his fingers moving in a blur. 

BOOM!

The ground shook beneath his feet. The sudden, concussive wave vibrated through the soles of his red shoes. 

Izuku stopped tying. He turned his head toward the source of the noise. A massive plume of thick, black smoke was rising into the sky a few blocks away, just past the shopping arcade. 

Explosion, Izuku analyzed. Not a gas line. The sound lacked the deep, sustained rumble of a structural ignition. It was sharp, crackling. Nitroglycerin-like.

Izuku frowned slightly. His mind instantly recalled a highly specific acoustic profile. 

Katsuki.

Izuku changed his trajectory. He didn't run—running wasted energy and raised the heart rate, clouding the mind. He walked briskly, his strides long and measured, navigating through the gathering crowd with fluid grace. 

As he approached the scene, the air grew incredibly hot. The smell of burning asphalt, melted plastic, and caramelized sugar filled his nostrils. He turned the corner into a wide alleyway connecting two main streets. 

It was a disaster zone. 

Fires raged out of control on both sides of the street. Storefronts were shattered, glass littering the pavement. A massive crowd of onlookers was held back by a thin line of police officers. Several Pro Heroes were on the scene: Death Arms, Kamui Woods, Mt. Lady, and a few others with water-based Quirks. 

But none of them were fighting. They were standing still, looking panicked and useless. 

Izuku slipped through the crowd, his small, unthreatening demeanor allowing him to weave to the front line without drawing attention. He analyzed the battlefield. 

In the center of the roaring flames stood a towering, undulating mass of dark green sludge. 

Izuku’s eyes narrowed slightly. The Sludge Villain. All Might must have lost containment when his form degraded. A gross oversight of basic protocol. He should have used a double-locking mechanism rather than standard plastic bottle caps.

But the villain wasn't alone. Embedded in the center of the sludge, thrashing wildly, was Katsuki Bakugo. 

Katsuki was firing explosions from his palms indiscriminately, roaring in panic and rage. But every explosion only fed the fires around them, creating a barrier of heat that kept the heroes at bay. The sludge absorbed the concussive force of the blasts, rippling but never breaking. Katsuki’s mouth was covered, the slime forcing its way down his throat. 

"It's no good!" Death Arms shouted, shielding his face from the heat. "I can't get close! There's no physical body to grab, and the fire is too intense!"

"My wood will ignite if I go in there!" Kamui Woods gritted his teeth, his wooden branches shifting uselessly. 

"I need a two-lane street to maneuver safely!" Mt. Lady cried, stuck in the narrow alleyway. "I can't squeeze in there without crushing the buildings!"

Izuku stood at the police tape, perfectly still. He listened to the heroes' excuses. He cataloged their failures. 

Death Arms relies on grappling and lifting. Useless against fluids. Kamui Woods possesses the optimal restraint Quirk, but his biological material is weak to thermal damage. Mt. Lady is a blunt instrument. They are all waiting for someone with a suitable Quirk to solve the problem for them. They lack tactical adaptability.

Izuku looked at Katsuki. 

The blonde boy's explosions were weakening. His eyes were bloodshot, bulging in absolute terror. He was asphyxiating. In less than two minutes, his brain would suffer irreversible hypoxic damage. 

Katsuki caught Izuku's eye through the crowd. In that single, desperate glance, all of Katsuki's arrogant pride was gone. It was a silent, suffocating plea for help. 

Most people would have charged in blindly, driven by adrenaline and emotion. 

Izuku Midoriya did not operate on adrenaline. He operated on physics. 

The villain is fluid, but he requires anchoring points to maintain his vertical structure against Katsuki's struggles, Izuku calculated, his eyes tracing the sludge. He has anchored himself to the asphalt and the surrounding debris. His only solid organs are his eyes. Last time, slicing him disrupted his mass, but Katsuki is inside him. Slicing might injure the hostage.

Izuku reached into his heavy canvas backpack. 

I need a Class-3 leverage system. I need to force a physiological shock to the villain's solid organs while simultaneously providing a secure extraction point for the hostage.

Izuku's hands moved with terrifying, practiced efficiency. He withdrew a heavy-duty climbing carabiner, a modified grappling hook made from reinforced steel rebar, and his two spools of wire. He quickly unclipped the heavy, reinforced nylon straps of his backpack, clipping the carabiner to his belt and feeding the wire through it, creating a makeshift pulley system on his own body. 

"Hey, kid! What are you doing?!" a police officer yelled, reaching out to grab him. "Get back behind the line!"

Izuku ignored him. He ducked under the tape, moving with a fluid, judo-like slide that slipped right past the officer's grasp. 

"Wait! Stop!" Death Arms roared, reaching for the boy. 

Izuku was already moving. He didn't sprint wildly. He darted into the inferno with a low, balanced run, his knees bent, his center of gravity close to the ground. The heat was immense, blistering his skin, but his high-collared, heavy denim jacket—which he had explicitly chosen for its thermal resistance—protected his neck and face. 

"What the hell is that kid doing?!" Kamui Woods shouted. "He's gonna burn to death!"

The Sludge Villain noticed him. "You again?! The little brat with the wires! I'm gonna kill you this time!"

The villain whipped a massive tendril of sludge toward Izuku, aiming to swat him into the burning buildings. 

Izuku didn't dodge backward. He analyzed the trajectory. Angle of attack: 45 degrees. Velocity: roughly 30 miles per hour. If I dive under, I lose momentum.

Izuku threw his grappling hook. 

The steel claws flew over the villain's head, wrapping securely around a wrought-iron balcony on the second floor of the burning building behind the villain. 

Izuku gripped the heavy nylon rope attached to the hook, planted his boots against the asphalt, and pulled. 

Using the rope and his momentum, Izuku swung his entire body into a horizontal slide, gliding under the massive sludge tendril with inches to spare. The sludge smashed into the ground where Izuku had just been, shattering the concrete. 

Izuku let go of the rope, using his slide to close the distance until he was directly beneath the towering mass of the villain. 

Katsuki looked down at him, his red eyes wide with shock. 

"Katsuki," Izuku said softly, though his voice cut through the roar of the flames with unnatural clarity. "Cease your explosions. You are consuming the localized oxygen."

Izuku didn't wait for a response. His hands were already moving. 

He gripped the two wooden spools. He needed the villain to loosen its grip. He needed a physiological shock. 

Izuku flicked his wrists upward. The high-tensile steel wires shot into the air like silver vipers. But instead of slicing, Izuku utilized the weighted ends of the wires, whipping them with absolute precision. 

Lasso trajectory: Intersecting arcs.

The wires snapped around the villain's two massive, bulbous eyes. 

With a rapid, complex twist of his wrists, Izuku tied a mid-air Clove Hitch around both eye stalks, pulling the slack taut in a fraction of a second. The steel wire bit viciously into the semi-solid tissue holding the eyes. 

"GRAAAAAAAAGH!" the villain shrieked in absolute agony. 

"Anchor set," Izuku murmured to himself. 

Izuku didn't just pull backward. That would require strength he didn't have. Instead, Izuku threw his arms in completely opposite directions, violently yanking the left eye to the right, and the right eye to the left, crossing the wires and creating immense, tearing tension on the villain's sensory organs. 

The physiological shock was catastrophic. The villain's concentration shattered. The fluid mass holding Katsuki convulsed, loosening its iron grip as the slime thinned out in a desperate attempt to retract its eyes. 

Katsuki's face was exposed. He gasped violently, sucking in a massive breath of smoke-filled air. 

"Katsuki! Now!" Izuku ordered, his voice echoing with absolute authority. "Right palm! Twenty percent yield! Direct it at the ground, concussive force only, no thermal sustain!"

Bakugo, acting purely on instinct and the sheer, commanding tone of the boy he had bullied for years, didn't argue. He aimed his right hand downward, pointing his palm directly at the sludge pooling around his boots. 

BOOM!

A sharp, concentrated blast detonated. It wasn't a fireball; it was a shockwave. 

The localized concussion ripped the thinned sludge apart, completely dislodging Katsuki from the villain's mass. Katsuki tumbled out of the slime, coughing violently, falling toward the asphalt. 

Izuku released the steel wires. He stepped forward, grabbing Katsuki by the collar of his uniform, smoothly redirecting the blonde boy's falling momentum into a controlled roll across the pavement, dragging them both out of the villain's immediate strike zone. 

The entire sequence—from Izuku crossing the police tape to Katsuki hitting the ground—took exactly six point four seconds. 

The crowd was dead silent. The Pro Heroes stood with their mouths hanging open. 

They had just watched a Quirkless middle schooler execute a flawless, tactical extraction of a hostage from a superior villain without throwing a single punch, utilizing nothing but geometry, physics, and a few pieces of hardware. 

The Sludge Villain, blinded, agonizingly tangled in steel wire, and furious beyond comprehension, let out a demonic roar. It rapidly gathered its mass, towering three stories high, preparing to bring its entire weight down on the two boys. 

Izuku stood up, smoothing down his high collar. He had calculated this, too. He had saved the hostage, but he lacked the containment tools for a fluid mass of this size. He had bought them approximately ten seconds of survival. It was mathematically sound. 

He prepared to deploy his climbing rope for a defensive weave. 

But he didn't have to. 

"I REALLY AM PATHETIC!" 

A massive figure burst through the wall of flames. It was All Might. But not the skeletal, coughing man from the tunnel. He was fully expanded, his muscles bulging, blood dripping heavily from his mouth. 

All Might had been watching. He had seen the heroes stand by. He had seen the Quirkless boy—the boy he had just told to give up—rush into the fire with nothing but a cold mind and absolute control. The sight of Izuku's elegant, terrifying bravery had struck a nerve deep within All Might's soul. It was a stark reminder of what true heroism was. 

All Might grabbed the villain by its tangled eye stalks. 

"PRO HEROES MUST ALWAYS RISK THEIR LIVES!" All Might roared, drawing back his fist. The air pressure in the alleyway inverted, a massive vacuum forming around his arm. "DETROIT... SMASH!"

The punch was cataclysmic. 

The sheer force of the shockwave didn't just obliterate the Sludge Villain; it extinguished the fires entirely, blowing the flames out like candles. The wind tore through the alleyway, creating a localized updraft so intense that clouds began to form in the sky above. 

Seconds later, a gentle rain began to fall over the shopping district. 

All Might stood victorious, steam rising from his massive frame, breathing heavily. 

The crowd erupted into deafening cheers. "He changed the weather! All Might changed the weather with a single punch!"

Izuku stood there, the rain pattering against his immaculate denim jacket. He looked at All Might, noting the severe tremors in the hero's legs and the blood pooling in his mouth. He pushed past his absolute limit. Highly irrational. His cellular decay will accelerate by at least twelve percent. A foolish, heroic action.

The aftermath was exactly as inefficient as Izuku had predicted. 

The police cordoned off the area to collect the scattered slime. The paramedics descended on Katsuki, checking his vitals and treating him for minor smoke inhalation. The Pro Heroes surrounded the two boys. 

Mt. Lady and Kamui Woods were kneeling next to Katsuki, showering the explosive boy with praise. 

"That was incredible endurance, kid!" Death Arms clapped Katsuki on the shoulder. "With a Quirk like yours, and a pain tolerance like that, you'll make an amazing Pro Hero one day! What's your name?"

Katsuki didn't answer. He sat on the back of the ambulance, a towel draped over his shoulders, glaring furiously at the ground. He wasn't looking at the heroes. He was glaring at the boy standing a few feet away. 

Izuku was surrounded by Death Arms and another police officer. They were not praising him. 

"Are you insane, kid?!" Death Arms scolded, his face red with anger. "What you did was incredibly reckless! You don't have a Quirk suited for that! You could have gotten yourself and the hostage killed! Leave the hero work to the professionals!"

"Yeah!" the police officer agreed. "You violated civilian engagement laws! You're lucky All Might showed up when he did!"

Izuku stood perfectly straight, his hands clasped behind his back. He listened to them yell for exactly thirty seconds. Then, he raised his head, his emerald eyes locking onto Death Arms with a gaze so cold and calculating the large hero physically flinched. 

"Professionalism," Izuku said, his voice calm, clear, and perfectly polite, "implies a standard of tactical competence. You stood by for three minutes and twenty seconds while a civilian asphyxiated. You cited the fire as your primary deterrent, yet you failed to utilize the local fire hydrants to create a steam barrier. You failed to calculate the villain's structural dependency on surface tension. My intervention utilized a Class-3 leverage system that safely extracted the hostage in under seven seconds with zero collateral damage to the surrounding infrastructure."

The heroes stared at him, completely dumbfounded. 

Izuku reached into his pocket, retrieved his two wooden spools, and meticulously began to coil his steel wire. 

"If the legal definition of 'professional' requires me to stand by and watch a boy die because my Quirk doesn't punch hard enough," Izuku continued smoothly, "then the system is fundamentally flawed. I did not act recklessly. I acted efficiently. I suggest you review the tactical footage of the incident and recalibrate your hostage negotiation protocols. Good evening."

Izuku bowed a perfect ninety degrees, turned on his heel, and began walking away. 

Death Arms opened his mouth to yell, but no sound came out. He felt like he had just been reprimanded by a seasoned general, not a middle schooler. 

"Deku!"

Izuku paused. He turned his head slightly. 

Katsuki had shoved past the paramedics and was storming toward him, his face twisted in a mixture of profound humiliation, rage, and confusion. 

"Listen to me, you Quirkless freak!" Katsuki yelled, his fists clenched tight at his sides. "I didn't ask for your help! I didn't need you! I was fine! I would have blown that sludge bastard away myself! You didn't do anything! You just... you just tied some stupid strings! Don't you dare look down on me! I owe you nothing!"

Katsuki was panting, his chest heaving, waiting for the smug retort. Waiting for Izuku to gloat. 

Izuku looked at Katsuki. He didn't see a rival. He didn't see a bully. He saw an inefficient use of emotional energy. 

"I am aware you did not ask for help, Katsuki," Izuku said softly, his tone completely flat. "And you owe me nothing. My intervention was a logistical necessity based on the heroes' failure to act. Your survival was simply the most optimal outcome of the equation. Do try to control your breathing; smoke inhalation can severely damage the elasticity of your lungs over time."

Izuku turned back around and continued walking into the twilight. 

Katsuki stood in the street, his hands trembling violently. He wanted to scream. He wanted to blow something up. But more than anything, he felt a terrifying, icy realization creeping into his bones. 

Deku wasn't beneath him anymore. Deku was operating on an entirely different plane of existence. 

The sun had fully set by the time Izuku turned down the quiet residential street leading to his apartment. The adrenaline of the day—though he kept it tightly suppressed—was beginning to wane, leaving him with a quiet, analytical hum in his brain. 

He needed to re-evaluate his equipment. The steel wires were effective, but too heavy for rapid aerial deployment. If he were to emulate Best Jeanist's mobility, he needed fibers that could act as an extension of his own nervous system. Perhaps a specialized gauntlet with tension-release spools...

"I AM HERE!"

Izuku stopped walking. 

Out of an alleyway ahead of him, All Might suddenly leaped out, striking his signature pose, his muscular form casting a long shadow under the streetlights. 

Izuku blinked. He pulled out a stopwatch from his pocket, clicked it, and noted the time. 

"All Might-san," Izuku said politely. "According to my calculations, you exceeded your physical limit approximately twenty minutes ago. Your continued manifestation of this form is medically suicidal."

Just as he finished the sentence, All Might violently expelled a massive cloud of steam, shrinking instantly back into his skeletal form. He coughed up a terrifying amount of blood, collapsing against a brick wall. 

"You... you really don't hold back, do you, kid?" All Might wheezed, wiping his mouth. 

"Honesty is the most efficient form of communication," Izuku replied, putting his stopwatch away. "Are you here to reprimand me for my civilian interference, or did you require medical assistance?"

All Might looked at the boy. He took a deep, rattling breath, steadying himself. 

"I came... to apologize," All Might said softly. "And to thank you. And to correct a mistake I made earlier today."

Izuku stood completely still, his eyes locked on the gaunt hero. 

"I told you earlier that Pro Heroes must risk their lives, that it requires overwhelming power," All Might said, stepping away from the wall. "I was a hypocrite. The Pro Heroes on the scene today... they had power. They had Quirks. But they did exactly what I did. They stood there, making excuses, waiting for someone else."

All Might placed a hand over his chest, right where his heart was beating against his ruined ribs. 

"But you... you didn't have a Quirk. You didn't have power. But you had absolute, terrifying control. You analyzed the situation, formulated a flawless tactical extraction, and moved when everyone else froze." All Might smiled, a genuine, gentle smile that looked out of place on his skeletal face. "Top heroes have stories about them from their school days. Most of their stories have one thing in common: their bodies moved before they had a chance to think."

Izuku frowned slightly. "That sounds incredibly reckless and tactically unsound. Unconscious movement implies a lack of situational awareness."

All Might let out a bark of laughter, shaking his head. "God, you're a stubborn one. Fine. Let me rephrase it. True heroes act when there is a need, using everything at their disposal. Today, that boy was saved because your sharp mind and absolute control paved the way."

All Might stood up straight. He didn't transform. He didn't need to. He radiated a profound, heavy aura of authority. 

"I was wrong, young man," All Might said, his voice echoing in the quiet street. "You can become a hero."

For the first time in his life, Izuku Midoriya felt a crack in his armor. 

He didn't cry. The tears didn't flow like a waterfall. But his breath hitched. The rigid, perfect posture he maintained at all times slumped just a fraction of an inch. His emerald eyes widened, and he had to clench his hands into fists to stop them from trembling. 

Validation. It wasn't the blind praise of an idol; it was the empirical, hard-earned validation of a Pro Hero recognizing his tactical methodology. 

"Thank you, All Might-san," Izuku whispered, his voice incredibly soft. "I... I appreciate your data."

"But I'm not just here to validate you," All Might said, stepping closer. "I am here to make you a proposition. You see, you have the mind, the control, and the spirit. But you are correct in your earlier assessment. My brawling style is flawed. It broke my body. I am looking for a successor. Someone who can inherit my power, but use it... differently. Smarter."

Izuku’s mind went blank. Then, it rebooted at a million miles an hour. 

"Inherit... your power?" Izuku's voice returned to its analytical clip. "Are you implying your Quirk is transferable? That contradicts every biological axiom regarding Quirk genetics. Quirks are somatic cell mutations, inextricably linked to the host's DNA. Transferring a Quirk would require a total genetic rewrite or an entirely separate, parasitic metaphysical energy source."

All Might stared at him. He rubbed his temples. "I swear, kid, you're going to give me an aneurysm. Yes. My Quirk is a special, transferable power. It is called One For All. It is a torch, passed from generation to generation, cultivating power."

All Might held out his hand. 

"I want to give it to you. Not to make you the next brawler. But to see what a mind like yours can do with the power of a god. Imagine combining your absolute control, your tactical genius, and your physical tools with the power of One For All."

Izuku looked at All Might's outstretched hand. 

His mind instantly simulated the possibilities. He imagined his steel wires, reinforced not just by leverage, but by immense kinetic energy. He imagined his leaps, calculating trajectories with superhuman speed. He imagined a hero who possessed the terrifying, immovable power of All Might, wielded with the surgical, elegant precision of Best Jeanist. 

A hero with no frayed edges. 

Izuku Midoriya looked up, his emerald eyes burning with a cold, focused fire. He reached out and grasped All Might's hand, his grip firm and perfectly controlled. 

"I accept your proposition, All Might-san," Izuku said clearly. "I will take your power. And I will weave it into something perfect."

The scent of Dagobah Municipal Beach Park was an oppressive cocktail of oxidized iron, rotting kelp, and stagnant saltwater. For years, the ocean currents had treated this stretch of coastline as a dumping ground, a massive, illegal landfill where the city’s broken appliances, rusted vehicles, and discarded industrial waste came to die. 

It was a graveyard of human consumption. And to All Might, it was the perfect crucible to forge a hero. 

The early morning mist clung to the mountains of trash as the Number One Hero, currently in his deflated, skeletal form, stood atop a rusted refrigerator. He looked down at his newly minted protégé. 

"The 'Aim to Pass: American Dream Plan!'" All Might declared, dramatically waving a thick stack of stapled papers. "I have calculated a rigorous, ten-month regimen designed to tear your muscles down and rebuild them stronger! You will haul trash, you will run through the sand, and you will eat exactly what I tell you! By the time the U.A. Entrance Exam arrives, you will be an empty, reinforced vessel capable of holding the torrential power of One For All!"

Izuku Midoriya stood at the base of the trash pile. He was wearing a fitted black tracksuit, zipped all the way up to his chin, his posture flawlessly straight. He reached out and took the packet of papers from All Might’s skeletal hand. 

Izuku opened the packet. He read the first page. His emerald eyes flicked back and forth, scanning the caloric intakes, the deadlift requirements, and the cardiovascular milestones. 

He flipped to the second page. Then the third. 

The silence stretched on for two full minutes. All Might shifted uncomfortably on the refrigerator, coughing lightly into his fist. "Well? I know it seems daunting, young Midoriya, but—"

"All Might-san," Izuku interrupted softly, closing the packet with a crisp snap. "This regimen is fundamentally designed for a hyper-trophic brawler. It emphasizes sheer mass and explosive kinetic output. If I follow this, I will develop the physique of a powerlifter."

"Exactly!" All Might beamed, pointing a bony finger at the boy. "You need a large, robust frame! If a Quirkless body tries to wield One For All without the proper mass, your limbs will literally blow off! It’s a lot of power, kid!"

Izuku nodded slowly, turning his gaze to a massive, half-buried pickup truck weighing at least two tons. "I understand the necessity of physical reinforcement to prevent somatic catastrophic failure. However, mass does not equate to durability. A thicker rope is not always stronger than a thin one; it depends entirely on the weave of the fibers. If I build bulky, hypertrophic muscle, I will sacrifice flexibility, joint mobility, and fine motor control."

Izuku reached into his heavy canvas backpack, which sat neatly on the sand. He pulled out a large, heavy-duty sketchbook and a pencil. 

"Furthermore," Izuku continued, rapidly sketching a diagram, "hauling these items using raw bicep and lower-back strength is a gross misuse of kinetic energy. It teaches the body to fight resistance head-on. That is the opposite of my operational philosophy."

All Might blinked, utterly lost. "But... but the trash needs to be moved to the trucks. That's the training."

"The trash will be moved, All Might-san," Izuku said, tearing the sketched page out and handing it up to the hero. "But I will not move it with brute force. I will move it with physics."

All Might looked at the paper. It was a complex blueprint of the beach. Izuku had diagrammed a series of Class-1 and Class-2 lever systems, block-and-tackle pulley networks, and A-frame winches, utilizing the existing trash—steel girders, washing machine drums, and discarded cables—as the raw materials to build the machinery.

"Instead of deadlifting a refrigerator," Izuku explained perfectly calmly, pulling a pair of thick, leather rigger’s gloves from his pockets, "I will construct a compound pulley system. Pulling the rope will provide intense, sustained isometric tension for my core, forearms, and latissimus dorsi. I will build my body for grip strength, tensile endurance, and balance. I must be a tightly wound spring, not a sledgehammer."

All Might stared at the blueprint. Then he looked at the fourteen-year-old boy, who was already walking toward a rusted steel beam, measuring its length with a tape measure. 

The Number One Hero sighed, a fond, bewildered smile crossing his gaunt face. He realized right then that he wasn't training a student. He was providing funding and supervision for a prodigy. 

"Alright, young Midoriya," All Might chuckled, stepping down from the fridge. "Let's build your pulleys."

The next ten months were a masterclass in mechanical engineering and physiological tailoring. 

Dagobah Beach did not look like a traditional training montage. There was no screaming at the sky, no veins popping out of Izuku’s forehead as he tried to drag a truck through the sand. Instead, the beach transformed into a quiet, hyper-efficient industrial logging camp. 

By Month Two, Izuku had scavenged enough high-tensile wire and steel bearings to build his first compound pulley system. He attached it to the heaviest items on the beach. All Might watched in stunned silence as Izuku, a boy who weighed barely a hundred and twenty pounds, stood firmly in the sand, wrapped a thick nylon rope around his waist and forearms, and leaned back. 

Using perfect leverage, a low center of gravity, and the mechanical advantage of the pulley, Izuku moved a three-ton truck twenty feet across the beach. His face was entirely devoid of panic or strain; his eyes were closed, focused purely on his breathing and the tension in the rope. 

He’s not just working his muscles, All Might realized, watching the boy's flawless posture. He’s conditioning his mind. He’s teaching his nervous system to process extreme stress without breaking composure.

By Month Five, Izuku had shifted his focus to agility and environmental navigation. 

He realized early on that if he was going to rely on a capture weapon—a specialized rope or wire—he needed to be able to move in three dimensions. The mountains of trash became his parkour course. All Might threw discarded tires and tennis balls at him while Izuku navigated the unstable, shifting piles of scrap metal. 

Izuku didn't just dodge. He used lengths of heavy denim, which he had begun buying in bulk from industrial fabric suppliers, wrapping them around his wrists. He would whip the denim ropes out, snagging a protruding pipe, and swing his body out of the way of All Might's projectiles. He practiced his knots in mid-air. He learned how to tie a bowline with one hand while falling. He learned how to decelerate his body mass by increasing the friction of the rope sliding through his palms, resulting in thick, permanent calluses covering his hands.

By Month Eight, Izuku’s body had transformed. 

He hadn't bulked up like a bodybuilder. Stripped of his high-collared tracksuit, Izuku looked like an Olympic gymnast or a professional rock climber. His muscles were incredibly dense, corded, and defined, packed tightly against his frame. His core was a wall of iron, designed to withstand the immense torque of arresting a falling object. His forearms and fingers possessed a terrifying, vice-like grip strength. 

He was a vessel built not to contain an explosion, but to channel an electric current.

Month Ten. The morning of the U.A. Entrance Exam. 

The sun peaked over the horizon, casting a golden glow over Dagobah Beach. The beach was completely pristine. The mountains of trash were gone. The golden sand stretched endlessly toward the sparkling ocean. 

At the edge of the water stood a massive, perfectly symmetrical cube of crushed cars, refrigerators, and steel girders. Izuku had not only cleared the beach, but he had also used his pulley systems to compress and stack the remaining scrap into a structurally sound, geometrically perfect monument of trash. 

All Might stood before the cube in his muscular form, his jaw slightly slack. He had meant for the boy to clear the beach, but this... this was an architectural feat. 

Izuku stood beside him, breathing in the salty air. His dark green hair was slightly longer, blowing gently in the wind. He wore his pristine junior high uniform, the collar buttoned tightly against his neck. 

"You never cease to amaze me, young Midoriya," All Might boomed, though his voice was thick with genuine emotion. "You didn't just complete the task. You optimized it. You controlled the environment perfectly."

"The environment is simply a tool, All Might-san," Izuku replied calmly, turning to face his mentor. "When you control the variables, chaos becomes impossible. I am physically prepared. My vessel is ready for the transfer."

All Might nodded slowly. The smile faded from his face, replaced by a solemn, heavy gravity. The power of One For All was not a toy. It was a legacy of blood, tears, and unimaginable burden. 

All Might reached up and plucked a single strand of golden hair from his head. 

"This Quirk... it is the culmination of generations," All Might said softly. "It is the crystallized prayers of those who came before. It is not just power; it is duty. Are you ready to shoulder the threads of their legacy, Izuku Midoriya?"

Izuku looked at the golden hair. He didn't see magic. He saw DNA. He saw a biological key. 

"I am ready to weave their threads into my own," Izuku said firmly. 

"Good." All Might held out the hair. "Eat this."

Izuku blinked. For three seconds, his perfectly composed facade faltered. "Pardon?"

"Eat it!" All Might laughed, returning to his boisterous persona. "To inherit the power, you have to ingest some of my DNA! A hair is the easiest way! Come on, we don't have time, the exam starts in three hours!"

Izuku stared at the hair. His mind immediately ran through the biological implications. 

"Gastric acid will immediately begin to denature the protein structures," Izuku muttered, pulling a small, sterilized vial and a pair of tweezers from his pocket. "However, if the Quirk factor is carried in the metaphysical energy attached to the genetic material, ingestion should initiate the somatic integration process within the digestive tract’s mucous membranes."

Izuku used the tweezers to take the hair, snapped it into three smaller, easier-to-swallow pieces, placed them on his tongue, and took a precise sip from his water bottle. He swallowed. 

"Integration initiated," Izuku stated, closing the water bottle. 

All Might sweatdropped. "Right. Well. It'll take about two hours for your body to fully process it. You'll feel it right around the time the practical exam starts. Remember, young Midoriya: you have power now. But do not use 100% of it right away. Your body is strong, but using the full output of One For All without practice will shatter your limbs like glass."

"Understood," Izuku said, bowing deeply. "I have no intention of using one hundred percent. To use a sledgehammer to drive a thumbtack is inherently flawed."

The gates of U.A. High School were massive, imposing structures of glass and steel. Thousands of students milled about, their faces painted with a mixture of excitement, terror, and determination. 

Izuku Midoriya walked through the gates with the steady, measured pace of a metronome. 

He didn't look up at the towering H-shaped building in awe. He scanned it, analyzing the architectural load-bearing columns and the security camera placements. He wore his junior high uniform, but slung heavily over his shoulder was a thick, reinforced duffel bag containing his U.A.-approved support gear. 

As he walked, he felt a strange, foreign sensation deep within his gut. It wasn't nausea. It felt like a small, infinitely dense coil of heat, humming with a terrifying, latent electricity. 

One For All, Izuku thought, placing a hand over his stomach. The digestion process is complete. The energy is integrating into my nervous system. It feels... volatile. Uncontrolled.

Izuku closed his eyes for a fraction of a second, walking purely on muscle memory. 

He visualized his body. He didn't picture a raging fire or a bursting dam. Those were chaotic metaphors. Instead, Izuku visualized his nervous system as millions of delicate, microscopic threads. The power of One For All was a massive spool of heavy, raw energy. If he forced the entire spool through a single thread, the thread would snap. His arm would explode. 

I must not isolate the power, Izuku calculated. I must unravel the spool. I must take the energy and weave it evenly through every single fiber of my body, reducing the overall voltage in a localized area but raising my baseline kinetic output entirely.

It was a complex theoretical application of the Quirk—one that All Might had never even considered, having relied entirely on localized "Smashes." But for Izuku, who had spent ten years mastering the distribution of tensile stress across multiple ropes, it was the only logical approach. 

"Outta my way, Deku!"

Izuku stepped smoothly to the side, exactly two inches, without breaking his stride or his visualization. Katsuki Bakugo stomped past him, glaring furiously. 

"Don't stand in front of me," Bakugo snarled. "I'm going to crush this exam, and if you get in my way, I'll blow you to ash."

"Good morning, Katsuki," Izuku replied evenly, his voice betraying absolutely no emotion. "Your gait is off-balance. Your left heel is striking the pavement heavier than your right. You slept on your left side and slightly compressed your sciatic nerve. I recommend a light hamstring stretch before the practical, or your explosive pivoting will be compromised."

Bakugo stopped walking. He slowly turned around, his eye twitching so hard it looked like a medical emergency. 

"I... will kill you," Bakugo whispered, sparks popping violently from his palms. "I will literally murder you."

"Murder on school grounds results in immediate disqualification," Izuku noted flatly. "Good luck on the written exam."

Izuku walked past him, leaving Bakugo standing frozen in a state of apoplectic rage. 

As Izuku approached the main entrance, he heard a sharp gasp. A girl with a brown bob and permanent blush stickers on her cheeks tripped over an uneven paving stone. She was pitching forward, a cry of alarm escaping her lips. 

Izuku's peripheral vision caught the trajectory of her fall. 

He didn't dive to catch her—diving was inefficient and would result in both of them tumbling. Instead, he snapped his left arm out. 

From the cuff of his uniform sleeve, a length of heavy, weighted denim rope shot forward like a striking snake. Izuku flicked his wrist, sending a wave of kinetic energy down the rope. The weighted end seamlessly looped around the girl’s waist just before her face hit the concrete. 

Izuku pulled backward, applying perfect leverage, and gently hoisted her back onto her feet. With a second flick of his wrist, the rope unspooled from her waist and snapped back into his hand, disappearing up his sleeve. 

The girl blinked, looking down at the ground, then up at Izuku, completely bewildered. 

"Woah," she breathed. "Did you... did you just catch me with a lasso?"

Izuku stopped, maintaining a respectable distance of three feet. He bowed his head slightly. "I apologize for restraining you without your consent. However, the vector of your fall indicated a high probability of facial lacerations upon impact with the pavement. Are you uninjured?"

Ochaco Uraraka stared at the boy. He was dressed flawlessly, his collar practically suffocating him, and his posture was as straight as a ruler. He spoke like a textbook, but his eyes were sharp and incredibly observant. 

"Uh, yeah! I'm fine!" Ochaco laughed nervously, rubbing the back of her head. "I guess my Quirk would have saved me—I can make things float—but I panicked! That was an amazing move! What's your Quirk? Rope manipulation?"

"I am currently unclassified," Izuku replied smoothly, a half-truth that legally protected him while One For All settled in his system. "My capture weapon is an approved support item. I advise you to tie your left shoelace; the aglet is currently trapped under your heel, which caused the initial loss of balance."

Ochaco looked down. Her shoelace was exactly as he described. When she looked back up, the boy with the green hair was already walking through the double doors, a silent, solitary phantom. 

"Unclassified?" Ochaco muttered, completely intrigued. "Who is that guy?"

The written exam was trivial. Izuku finished the complex algebra, applied physics, and legal doctrine sections in half the allotted time, spending the remaining hour mentally refining the weave of his denim ropes. 

Then came the orientation for the Practical Exam. 

The auditorium was massive. Pro Hero Present Mic stood on the stage, screaming into the microphone, outlining the rules. Destroy the robots. One-pointers, two-pointers, three-pointers. And the Zero Pointer—the massive obstacle to be avoided. 

Izuku sat perfectly still, his eyes locked on the screen behind Present Mic. The screen displayed silhouettes of the robots. 

Wheeled propulsion systems on the one-pointers, Izuku noted rapidly in his sketchbook. Bipedal articulation on the two and three-pointers. The joints are exposed. Heavy armor plating on the chassis, but optical sensors and exhaust ports are unarmored. Brute force is the intended solution, but structural sabotage will be significantly faster and require less caloric expenditure.

"Excuse me!" 

A tall boy with glasses and perfectly combed blue hair stood up sharply, pointing rigidly at Present Mic. "On the printout, there are four types of villains! If this is a misprint, U.A., the top hero agency in Japan, should be ashamed of that foolish mistake! Furthermore!" 

The boy spun around, pointing directly at Izuku’s section of the seating. 

"You in the back with the curly hair!" Tenya Iida barked. "You have been writing in your notebook nonstop since the presentation began! If you are not taking this seriously, then leave immediately! You are distracting the rest of us!"

The entire auditorium turned to look at Izuku. Bakugo, sitting two rows ahead, grinned maliciously. 

Izuku didn't flinch. He slowly closed his notebook. He stood up, smoothing down the front of his jacket. 

"I apologize if the sound of my pencil disrupted your concentration," Izuku projected his voice perfectly, crisp and clear, carrying across the silent auditorium. "However, Present Mic-sensei provided only brief visual silhouettes of the target hardware. I was calculating the turning radius and the blind spots of the bipedal units based on the axle placement shown on the slides. Given that our physical safety is at risk, analyzing the enemies' mechanical weaknesses is a critical priority."

Izuku turned his gaze specifically to Iida. 

"Furthermore, the fourth robot was clearly designated on page three of the syllabus as an 'obstacle' worth zero points, intended to test situational awareness and evasion. I respectfully suggest you review the provided materials thoroughly before accusing the faculty of a misprint."

Izuku bowed respectfully and sat back down. 

Iida stood frozen, his mouth opening and closing like a fish. A deep, embarrassed flush crept up his neck. He bowed frantically toward the stage and sat down, completely chastised by a boy who hadn't raised his voice a single decibel. 

On the stage, Present Mic grinned behind his sunglasses, turning off his microphone for a second to whisper to the control room. "Hey, Eraser? Did you catch that kid in the back? The polite one?"

In the dark control room high above the mock cities, Shota Aizawa stared intently at the monitor displaying Izuku Midoriya. 

"Yeah," Aizawa grunted, taking a sip from a jelly pouch. "He didn't just read the pamphlet. He read the room. Let's see if his physical skills match his mouth."

Test City Beta. 

The massive gates stood closed. Hundreds of teenagers stretched, jumped, and activated their Quirks, hyping themselves up into a frenzy of adrenaline. 

Izuku stood at the very front of the crowd, mere inches from the gate. 

He was no longer wearing his school uniform. He had received permission to wear his custom support gear—a prototype of the costume he had designed. 

It was striking. He wore a dark, heavy, reinforced denim jumpsuit. It was incredibly fitted to prevent snagging, but woven with flexible, impact-resistant synthetic fibers. Thick, padded bracers covered his forearms. A wide, utilitarian utility belt rested on his hips. And true to his idol, a rigid, high denim collar extended all the way up to the bridge of his nose, hiding his lower face entirely, making his calculating green eyes the only visible feature. 

Slung across his torso and wrapped around his forearms were spools of heavy, dark indigo rope. The rope was made of compressed denim infused with carbon fiber, tipped with small, heavy steel weights. 

Breathe in, Izuku thought, his eyes locked on the gates. Four seconds.

Deep inside him, the dormant energy of One For All throbbed. 

Hold. Two seconds.

Izuku reached into his mind. He grabbed the "spool" of One For All. He didn't rip it open. He carefully, meticulously pulled a single, infinitesimally thin thread of energy, routing it through his nervous system, weaving it into the fibers of his muscles. 

Breathe out. Six seconds.

Faint, glowing red lines briefly pulsed under Izuku's skin, followed by a barely visible aura of green static electricity crackling around his boots. 

One For All: Five Percent Distributed Weave. Engaged.

Izuku felt a wave of absolute, terrifying power wash over him. His senses sharpened to a razor's edge. He could hear the hum of the hydraulics behind the gates. He felt lighter than air, yet anchored to the earth with the density of tungsten. He had contained the storm. 

"START!" Present Mic’s voice boomed over the speakers. 

Most of the students froze, waiting for a countdown. 

Izuku vanished. 

He didn't run. The five percent output of One For All turned his perfectly executed, mechanically efficient stride into a blinding blur. He crossed the threshold of the gates a full three seconds before anyone else even twitched. 

"What are you waiting for?!" Present Mic yelled. "There are no countdowns in real battles! The kid with the high collar has the right idea! Go, go, go!"

The crowd surged forward, but Izuku was already two blocks deep into the mock city. 

A One-Pointer rolled out from an alleyway, its single red optical sensor locking onto Izuku. "TARGET ACQUIRED."

Izuku didn't slow down. He didn't cock his fist back for a smash. 

As he ran past the robot, his hands flicked outward with the grace of a dancer. Two lengths of denim rope shot from his sleeves. The weighted ends whipped around the robot's left and right wheel axles. Izuku didn't stop running; he simply gripped the ropes tight and let his forward momentum and the five percent enhancement of One For All do the work. 

CRUNCH.

The sheer tensile force ripped the axles completely out of their sockets. The One-Pointer collapsed face-first onto the pavement, sparking violently as Izuku retracted his ropes, already moving to the next target. 

One point.

A Two-Pointer dropped from a rooftop directly in front of him, its bipedal legs absorbing the impact. Its tail swung like a club. 

Izuku slid on his knees, passing directly under the heavy tail swing. He looked up, his eyes locking onto the exposed hydraulic joint behind the robot's mechanical knee. 

Instead of using his ropes, Izuku decided to test his physical output. 

He planted his left hand on the pavement, using his momentum to pivot his body, and delivered a precise, surgical kick directly to the hydraulic joint. 

He didn't yell. He didn't put 100% of his power into it. It was a purely mechanical, five-percent strike aimed at a structural weak point. 

The kick shattered the reinforced steel joint like glass. The Two-Pointer’s leg buckled instantly, the heavy chassis tearing its own wiring apart as it crashed into the side of a building, completely immobilized. 

Three points.

In the control room, the Pro Heroes watched the monitors in stunned silence. 

"Who is the kid in the denim?" Midnight leaned forward, her eyes wide. "His movements... they're completely silent. He's dismantling them."

"Izuku Midoriya," Nezu, the principal, hummed, taking a sip of tea. "He requested a waiver for physical capture gear. Fascinating. He possesses an enhancement Quirk, but he's not relying on it to deal damage. He's using it purely for speed and leverage."

"It's terrifyingly efficient," Aizawa noted, his tired eyes locked on Izuku's screen. "He's not fighting the robots. He's executing them. He goes straight for the mobility joints, the optic sensors, or the power cables. He hasn't wasted a single calorie of energy on a flashy attack. He moves like a Pro who’s been doing this for ten years."

Down in the mock city, Izuku was a ghost of indigo and green lightning. 

He bounded off a wall, using his ropes to grapple onto a streetlight, swinging himself over a pack of three Three-Pointers. As he passed over them, he dropped three small, weighted loops of denim. The loops perfectly snared the protruding exhaust pipes on the backs of the robots. Izuku yanked the ropes upward as he landed on the roof of a building, forcefully crushing the exhaust pipes shut. 

Within seconds, the three robots overheated, their engines stalling out in a cloud of black smoke. 

Thirty-two points, Izuku counted internally. Based on historical data, the cutoff for the hero course is roughly forty points. A safety margin of fifty points is optimal.

He breathed deeply, maintaining his five percent weave. His body ached slightly—a dull throb in his muscles, protesting the foreign energy—but there were no broken bones. The distribution was holding. 

Suddenly, the ground shook. 

It wasn't a localized tremor. The entire mock city vibrated violently, the windows of the fake buildings shattering from the acoustic resonance. 

Izuku stood on the edge of the rooftop, looking down the main avenue. 

A shadow fell over the city. The Zero Pointer. 

It was a monstrosity of steel and gears, towering higher than the skyscrapers. Its massive treads crushed the pavement to dust, and its singular, glowing red eye swept the street below. 

Panic erupted. The other examinees screamed, abandoning their fights, turning and sprinting in the opposite direction. 

"It's the obstacle! Run!"

"That thing is massive! We're gonna die!"

Izuku watched the machine. His mind remained icy. 

Zero points. No tactical advantage to engaging. Time remaining: three minutes. Optimal strategy: evacuate the immediate sector and secure remaining straggler points.

Izuku turned to leave. 

"Ow! Help! My leg is stuck!"

Izuku froze. 

He looked down at the street level. Through the thick cloud of dust and debris kicked up by the Zero Pointer's advance, he saw her. The girl with the bob haircut—Uraraka. 

She was trapped under a massive slab of concrete that had fallen from a destroyed building. The Zero Pointer was advancing slowly, its massive treads less than fifty meters away. She was directly in its path. 

The other students ran past her. Even the boy with the glasses, Iida, hesitated, his face pale with terror, before the sheer survival instinct forced him to retreat. 

In the control room, All Might gripped the edge of the console, his knuckles turning white. Midoriya! What will you do? Your control is perfect, but this requires power! You cannot stop that thing with ropes!

Izuku stood on the roof. 

He looked at the girl. He looked at the massive treads of the robot. 

Most people would have panicked. Most people would have deactivated their restraints, flooded their arm with 100% of One For All, and leaped into the sky to deliver a catastrophic, self-destructive punch. 

Izuku's emerald eyes narrowed above his high collar. 

The chassis is too heavily armored for a blunt force strike at a safe output percentage, Izuku calculated, his mind working in microseconds. If I use 100%, my limbs will shatter, rendering me incapable of evacuating the civilian if the robot falls forward. Punching the robot is mathematically unacceptable.

He analyzed the robot's structure. 

Every machine requires a central processing unit to coordinate bipedal or tread-based articulation. U.A.'s patents for large-scale robotics house the CPU behind the primary optical sensor, protected by a blast shield. However, the blast shield must periodically open to vent excess thermal energy from the core.

Izuku checked his equipment. He had forty feet of high-tensile denim rope remaining. 

Calculations complete. Commencing surgical strike.

Izuku leaped off the building. 

He didn't jump toward the robot. He jumped sideways, aiming for a towering skyscraper adjacent to the Zero Pointer. 

"What is he doing?!" Midnight gasped in the control room. "He's not running away, but he's not attacking it!"

Izuku hit the glass facade of the skyscraper. He channeled his five percent weave into his boots, sprinting vertically up the side of the glass building, defying gravity through pure kinetic speed. 

He reached the top of the skyscraper, now parallel with the Zero Pointer's massive head. 

Below, the robot raised its colossal arm, preparing to smash the street where Uraraka was trapped. 

Izuku didn't hesitate. He whipped his right arm forward, deploying his heaviest, thickest length of carbon-infused denim rope. 

The rope shot across the gap between the building and the robot. The weighted end lashed out, wrapping securely around the massive, antenna-like protrusion on the side of the Zero Pointer's head. 

Izuku gripped the rope with both hands. He stepped off the edge of the skyscraper. 

He became a pendulum. 

Swinging on the seventy-foot arc of the rope, Izuku hurtled through the air, accelerating at a terrifying velocity directly toward the face of the massive machine. The wind roared past his ears. 

Wait for it, Izuku thought, his eyes locked on the robot's glowing red eye. 

The Zero Pointer's internal temperature spiked as it prepared to bring its fist down. 

Hiss. 

A heavy steel plating directly above the red optical sensor slid backward, revealing a glowing blue exhaust port—the thermal vent for the CPU. 

Target acquired.

Izuku reached the apex of his swing, hurtling directly toward the open vent. 

He didn't need 100%. He didn't need to break his arm. 

One For All Weave: Localize to right leg. Output: Ten Percent.

Izuku let go of the rope. He spun in mid-air, a fluid, beautiful crescent kick, and drove his right boot directly into the glowing blue exhaust port. 

"Release," Izuku whispered behind his collar. 

The impact wasn't a booming explosion. It was a sharp, localized, devastating transfer of kinetic energy directly into the robot's delicate internal circuitry. 

CRACK-ZZZT!

The ten percent output shattered the cooling fans, driving the shrapnel deep into the motherboard. 

The Zero Pointer froze instantly. Its massive, raised fist stopped mid-air. The glowing red eye flickered, sparked violently, and went pitch black. The internal generators whined, a cascading series of electrical failures ripping through the chassis. 

Slowly, the massive machine tilted backward, away from Uraraka, and crashed onto the empty street behind it with a deafening, earth-shaking roar. 

Silence descended upon the mock city. 

In the sky, Izuku was now in freefall, plummeting two hundred feet toward the concrete. 

He had localized ten percent to his leg. His calf muscle was screaming, slightly torn from the sudden burst of energy, but the bone was intact. He was fully conscious, completely aware of his trajectory. 

Terminal velocity approaching. Deceleration required.

Izuku didn't panic. As he fell past the adjacent buildings, his hands moved in a blur. He deployed two lengths of rope from his bracers, firing them at the rooftops on either side of the street. 

The ropes caught. 

Izuku gripped the ends tightly. He didn't lock his arms—that would dislocate his shoulders. Instead, he let the ropes slide through his heavily calloused palms, using the intense friction to bleed off his downward momentum. 

Smoke literally rose from his leather gloves as he slid down the ropes. 

He came to a stop, suspended upside down, exactly three feet above the pavement, right in front of the stunned Uraraka. 

Izuku calmly released the ropes, executing a flawless backflip, and landed silently on his feet. 

He stood up, adjusting his high denim collar, brushing a speck of dust from his sleeve. He walked over to the concrete slab pinning Uraraka. 

"Ten percent output should suffice," Izuku murmured to himself. He gripped the edge of the slab, engaged his distributed weave, and lifted the massive piece of concrete effortlessly, tossing it to the side. 

Izuku offered his gloved hand to the girl on the ground. 

"The structural threat has been neutralized," Izuku said politely, his breathing perfectly even, betraying no sign of the physical exertion he had just endured. "Are your lower extremities functional?"

Uraraka stared at the gloved hand. She looked past him at the smoking, decapitated ruin of the Zero Pointer. She looked back at the boy in the denim suit who hadn't even broken a sweat. 

"You... you swung," Uraraka stammered, taking his hand as he pulled her up. "You swung like a spider... and you just... kicked it."

"Brute force is inefficient against heavy armor," Izuku replied simply. 

"TIME'S UP!" Present Mic's voice echoed through the city, signaling the end of the exam. 

The other examinees slowly crept back out from their hiding spots, staring at Izuku with a mixture of absolute awe and terror. 

"He took down the Zero Pointer..."

"He didn't even use a flashy Quirk! He just used those ropes!"

"Who the hell is this guy?!"

In the control room, the silence was absolute. 

All Might let out a breath he didn't know he was holding. He covered his face with his hand, a massive, proud smile stretching across his face. You didn't just survive the transfer, my boy. You reinvented the Quirk entirely.

Aizawa unzipped his sleeping bag, his eyes completely wide. 

"He assessed the armor," Aizawa muttered, staring at the screen. "He found the one micro-second window where the vent opened. He used physical gear to achieve aerial dominance, and applied localized concussive force to the CPU. He completely neutralized a Class-A threat without causing a single point of collateral damage to the city or himself."

Nezu, the principal, giggled softly, pouring a fresh cup of tea. 

"Gentlemen, and ladies," Nezu smiled, his eyes gleaming. "I believe we have just witnessed the debut of an entirely new species of hero."

One week later. 

Izuku sat perfectly still at the small desk in his bedroom. His room was pristine, devoid of clutter, meticulously organized. 

Inko Midoriya slowly cracked the door open, holding a heavy envelope stamped with the wax seal of U.A. High School. Her hands were shaking violently. 

"I-Izuku," Inko whispered, tears already forming in her eyes. "It's here."

Izuku stood up, walked over, and took the envelope. "Thank you, Mother. Please, do not distress yourself. Whatever the outcome, it is simply data to inform my next trajectory."

Inko nodded, stepping out of the room to let him open it in private. 

Izuku walked back to his desk. He took a silver letter opener, sliced the seal with perfect precision, and emptied the contents. 

A small metal disc fell onto the desk. 

A holographic projection flickered to life. All Might, in his yellow suit, pointed directly at the camera. 

"I AM HERE AS A PROJECTION!" All Might boomed. 

Izuku sat down, his hands folded neatly in his lap. 

"Young Midoriya!" All Might's hologram smiled warmly. "You performed exceptionally well on the written exam! A perfect score, in fact! But the practical exam... my boy, you gave the judges quite the shock! You scored thirty-five villain points!"

Izuku calculated rapidly. Thirty-five. Lower than my estimation of forty. The baseline cutoff is usually higher. Did I fail? His face remained perfectly impassive. 

"However!" All Might continued, gesturing to a video screen that appeared beside him in the hologram. It showed Izuku leaping off the building to save Uraraka. "A hero course does not grade solely on villain destruction! How could we reject someone who risks their life to save others? We have a hidden metric! Rescue Points!"

The screen flashed, showing the judges' scores. 

"Izuku Midoriya! Sixty Rescue Points! For a grand total of ninety-five points! You have achieved the highest score in the history of the entrance exam!"

All Might reached his hand out, as if offering it through the hologram. 

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

The hologram faded out. 

The room was silent. 

Izuku sat at his desk for a long time. He looked down at his calloused hands. He closed his eyes and breathed in, feeling the faint, controlled hum of One For All resting beneath his skin. 

He had done it. He had taken the most volatile, destructive power in the world, and he had woven it into his own design. 

A small, imperceptible smile tugged at the corner of Izuku's mouth. 

He reached out, grabbed his sketchbook, and turned to a blank page. 

U.A. High School Curriculum Analysis, he wrote neatly at the top. Preparation for tactical engagement.

The threads were set. Now, it was time to weave a masterpiece.
