What if deku was Principal nezu little brother

 

The rain did not care that he was a genius. 

It was a cold, unforgiving downpour, the kind that chilled a creature down to the very marrow of its bones. It turned the grease-stained asphalt of the Musutafu alleyway into a slick, freezing mirror, reflecting the flickering neon lights of a society that had no place for an anomaly like him. 

He huddled behind a rusted dumpster, shivering violently. His white fur was matted with mud, motor oil, and the copper-scented crimson of his own blood. A ragged, jagged gash stretched across his flank, a parting gift from the electrified fencing of the laboratory he had just managed to escape. His small, clawed hands—paws that possessed more dexterity than any human surgeon's—were wrapped tightly around himself, trying in vain to preserve whatever body heat remained.

They will be looking for me, the creature thought, his hyper-intelligent mind calculating the exact probability of his recapture. Given the response time of the facility's private security and the deployment radius of their tracking hounds, I have approximately fourteen minutes before this sector is locked down.

He closed his beady black eyes, a profound sense of exhaustion settling over him. He was an experiment. A fluke of genetics. An animal that had spontaneously manifested a Quirk—High Spec. It had granted him an intellect that vastly surpassed humanity's brightest minds. And what had humanity done with that revelation? They had locked him in a cage. They had run voltage through his nervous system. They had tested his pain threshold, his cognitive reasoning, his very right to exist. 

He hated humans. He hated their arrogance, their cruelty, their inherent belief that the world belonged solely to them. If he died here, freezing in an alleyway, at least he would die free from their sterile, white-tiled rooms.

Scuff. Splash.

Footsteps. 

The creature’s eyes snapped open, his ears swiveling. The footsteps were light, erratic, lacking the heavy, militaristic cadence of the facility's guards. But human nonetheless. He bared his sharp teeth, pressing his injured body further into the shadows. If they touched him, he would bite. He would fight until his heart gave out.

A silhouette appeared at the mouth of the alley. It was a woman, holding a clear plastic umbrella. She had plump, soft features and hair the color of fresh spring leaves. She was carrying a plastic grocery bag, the unmistakable smell of cheap ground beef and green onions wafting from it. 

The woman paused. She looked down at the puddle near her boots, and then her eyes tracked the faint, bloody paw prints leading into the darkness behind the dumpster.

The creature held his breath. Walk away, he projected the thought with every ounce of his willpower. Do what your species does best. Ignore the suffering in the shadows. Walk away.

The woman did not walk away. 

Slowly, carefully, she stepped into the alley. She knelt down, the knees of her sensible slacks soaking up the dirty water, completely heedless of the grime. She lowered the umbrella, tilting it so that the rain stopped pelting the creature's shivering form.

"Oh," she breathed, her voice carrying a timbre that the creature had never heard before. It wasn't the clinical detachment of a researcher. It wasn't the bark of a guard. It was... sorrow. Genuine, unadulterated sorrow. "Oh, you poor, poor thing."

The creature hissed, snapping his jaws. Stay back! he tried to communicate. I am dangerous. I am a monster.

The woman didn't flinch. She gently set her groceries on the wet ground. "It's okay," she whispered

The chalkboard at the front of the classroom was a smudged canvas of mathematical equations, but Izuku Midoriya wasn’t looking at it. His emerald eyes were fixed on the intricate sketch of the Pro Hero Mt. Lady he had just finished in his notebook, Hero Analysis for the Future No. 13. He was currently cross-referencing her gigantification quirk with the tensile strength limits of woven carbon-fiber hero costumes, mentally drafting a design that would prevent the structural tearing she seemed to suffer during rapid expansion.

It was high-level collegiate physics mixed with advanced support-gear engineering. It was the kind of work that would have earned him a nod of approval and a fresh pot of Earl Grey tea from his older brother. 

But Izuku wasn’t at home in the fortified, high-tech sanctuary of U.A.’s residential sectors. He was sitting at a chipped wooden desk in Aldera Junior High, surrounded by the suffocating mediocrity of an education system that viewed him as fundamentally broken. 

"You're all third-years now!" the homeroom teacher announced, his voice carrying the obnoxious, booming cadence of a man who enjoyed the sound of his own authority. "It's time to start thinking seriously about your futures! I would hand out these career aptitude tests, but who are we kidding? You all want to be heroes!"

The teacher threw the stack of papers into the air. The classroom erupted into a cacophony of flashing Quirks—elongated fingers, localized miniature rainclouds, popping sparks, and minor levitation. It was a chaotic display of genetic lottery winnings, none of which were particularly impressive to a boy whose older sibling could crash the Japanese stock market from a laptop before breakfast.

Izuku kept his head down, meticulously adding a footnote about aerodynamic drag coefficients to his notebook. He didn’t raise his hand. He didn’t activate a Quirk. He simply existed in his own quiet bubble, waiting for the bell to ring so he could escape.

"Yes, yes, you all have wonderful Quirks," the teacher chuckled, waving a hand to settle them down. "But remember, using them in school is against the rules. Now, let's see... Oh, Bakugo. You're aiming for U.A. High, aren't you?"

The temperature in the room seemed to spike. 

Katsuki Bakugo leaned back in his chair, his feet kicked up onto his desk. He exuded an aura of supreme, unearned confidence. "Don't lump me in with these crappy side characters," Bakugo scoffed, a feral grin stretching across his face. "I'm the real deal. I've aced the mock tests, and I'm the only one here with the raw power to even stand a chance. I'll surpass All Might himself and become the top hero! U.A. is just the first stepping stone!"

The class murmured in a mix of annoyance and awe. The teacher hummed in agreement. "Ah, yes. You do have the grades for it. Oh, and... Midoriya. You're applying for U.A. too, aren't you?"

The silence that fell over the room was absolute. It was the kind of silence that preceded an execution. 

Izuku froze, his pencil snapping loudly in his grip. He squeezed his eyes shut. Why did you have to say that? he thought, a familiar weariness washing over him. You know exactly what happens when you say that.

For a split second, nobody moved. Then, the entire class erupted into cruel, raucous laughter.

"Midoriya? Seriously?"

"The Quirkless wonder?"

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

Izuku kept his eyes glued to his desk, carefully brushing the graphite shavings from his notebook. He had long since stopped trying to defend himself. It was a waste of breath. Nezu had taught him that trying to reason with an irrational mob was a fool's errand. “Let them laugh, Izuku,” his brother had told him over a game of chess. “Lions do not lose sleep over the opinions of sheep. Or, in my case, the opinions of poorly-educated bipeds.”

"Hey, Deku!" 

Before Izuku could react, a hand slammed down on his desk. The smell of burnt caramel and ozone flooded his senses. Bakugo was standing over him, his crimson eyes blazing with an irrational, violent fury. 

"Listen up, you Quirkless wannabe," Bakugo hissed, small explosions popping in his palms, singeing the wood of Izuku's desk. "You're worse than the rest of these rejects. You're completely unblessed. You really think you can stand in the same arena as me? You think you can rub shoulders with the best when you don't even have a Quirk?"

"I-It's not a competition, Kacchan," Izuku said softly, his voice remarkably steady despite the proximity of the explosions. He had sat through interrogations with the Pro Hero Hound Dog just for practice; Bakugo’s intimidation tactics were loud, but fundamentally hollow. "The rules were changed a few years ago. There's no regulation stating a Quirkless person can't apply. I just... I want to try."

"Try?" Bakugo snarled, snatching the notebook right out from under Izuku’s hands. Hero Analysis for the Future No. 13. 

"Hey, give that back," Izuku said, a flicker of genuine alarm crossing his face. That notebook contained proprietary encrypted data on several active Pro Heroes. If it fell into the wrong hands—

Bakugo didn't even look at the cover. He slammed his explosive palms together, catching the notebook directly in the blast. 

BOOM.

The sound echoed through the classroom. Izuku flinched, the heat washing over his face. When the smoke cleared, the notebook was a charred, smoking ruin. 

"Hmph. 'For the future'," Bakugo mocked. He turned toward the open window and casually tossed the smoldering book out into the three-story drop. "Most top-tier heroes have stories about their school days. They always talk about how they were the only ones from their crappy middle schools to make it. I'm going to be the only one from Aldera. That's my origin story. So, do me a favor, Deku."

Bakugo leaned in close, his face twisted into an ugly, cruel sneer. He placed a smoking hand on Izuku's shoulder, burning a hole straight through his uniform blazer.

"Don't apply to U.A. If you really want a Quirk that badly, there might be another way. Just pray you'll be born with a Quirk in your next life, and take a swan dive off the roof of the building."

The classroom went dead silent. Even Bakugo’s lackeys looked slightly uncomfortable. The teacher, pretending he hadn't heard a thing, busied himself with the chalkboard.

Izuku sat perfectly still. 

He didn't tremble. His eyes didn't well up with tears. He didn't shrink back in fear. 

Instead, Izuku slowly turned his head to look at Bakugo. The look in his emerald eyes was not one of despair, nor was it anger. It was something that unsettled Bakugo so deeply that the blond boy instinctively took a half-step back.

It was pity. Cold, profound, overwhelming pity. 

Izuku looked at Bakugo the way one might look at a terminally ill patient who didn't yet know they were sick. He looked at him with the chilling realization of exactly who Bakugo had just threatened.

Bakugo had just told the little brother of Principal Nezu to commit suicide. 

"What are you looking at, damn nerd?" Bakugo barked, though his voice lacked its usual venom, replaced by a sudden, inexplicable defensive edge. 

Izuku blinked, the coldness vanishing, replaced by a weary sigh. He stood up, packing his remaining pens into his bag. He slung the strap over his shoulder.

"Nothing, Kacchan," Izuku said quietly. "Just... please be careful going home today."

Without another word, Izuku walked past him and out the classroom door, leaving Bakugo standing there, a strange shiver running down his spine.

The koi pond behind the school building was muddy and choked with algae. Izuku knelt by the edge, his uniform pants getting damp as he reached out to retrieve his notebook. It was floating among the aggressive, orange fish who were attempting to nibble at the charred edges. 

"Stupid fish," Izuku murmured, gently swatting one away. "That's not food. That's highly classified analysis on Kamui Woods' pre-ignition vulnerability limits."

He pulled the dripping, ruined notebook from the water. It was unsalvageable. The pages were fused together by heat and water, the ink bleeding into indecipherable blue and black smears. 

Izuku stared at it, a heavy knot forming in his chest. He wasn't crying over the notebook itself. He had all the data backed up on a secure, triple-encrypted server located in a sub-basement of U.A. He was mourning what the destroyed book represented.

He had stayed at Aldera Junior High because of a foolish, sentimental desire for normalcy. When his mother, Inko, had brought Nezu into their home all those years ago, their lives had fundamentally changed. They were no longer an average family. They were the legally protected kin of the smartest, most politically dangerous being on the planet. 

Nezu had offered to pull Izuku out of public schooling years ago. He had offered him private tutors, early admission to university-level engineering courses, or a permanent place in the U.A. ecosystem. But Izuku had begged to stay at Aldera. He had wanted to experience a normal middle school life. He had wanted to see if he and his childhood friend, Kacchan, could ever mend the bridge that Quirks had burned.

Today, Bakugo had taken an explosive to that bridge, and then told him to jump off it. 

"Normalcy is overrated," Izuku whispered to the wind. He squeezed the excess water out of the notebook, tucked it under his arm, and began the long walk home. 

The Midoriya residence was located in an upscale, highly secure apartment complex in Musutafu, a building entirely owned by a shell corporation that traced back to a holding company managed by U.A. High School. To the outside world, it looked like a nice place to live. To anyone with a background in security, it was a fortress. The windows were ballistic glass, the elevators required retinal scans, and the lobby concierge was a retired underground Pro Hero. 

Izuku bypassed the elevator and took his private biometric lift directly to the top floor. The doors slid open to reveal a spacious, warmly lit apartment that smelled of cinnamon, old paper, and highly expensive Darjeeling tea. 

"I'm home," Izuku called out, toeing off his red sneakers in the genkan. 

"Welcome back, Izuku!" 

From the kitchen, his mother, Inko, bustled out. She was wiping her hands on an apron, her face lighting up with a brilliant smile. She looked exactly as she always did—kind, warm, and utterly unbothered by the fact that her eldest "son" was currently sitting on the living room sofa, dismantling the Japanese Ministry of Defense's firewall for fun.

"How was school, sweetie?" Inko asked, coming over to inspect him. Her eyes immediately snagged on the scorched hole in his blazer shoulder. Her smile faltered. "Oh, Izuku. Did Katsuki have another... accident?"

"It's fine, Mom," Izuku said, giving her a reassuring hug. "Just a little collateral damage. I'll take it to the tailor tomorrow."

"If you say so," she sighed, though there was a knowing sadness in her eyes. She patted his cheek. "Dinner will be ready in an hour. Your brother is in the living room. Try not to interrupt him if he's doing that thing with his eyes, you know the one."

Izuku chuckled. "I know."

He walked into the sunken living room. Sitting in a custom-made, plush armchair was Principal Nezu. The chimera was dressed in an immaculate, tailor-made three-piece suit, a gold pocket watch chain draped across his vest. He was holding a delicate porcelain teacup in one paw, while the other manipulated a tablet at blinding speeds. 

At the sound of Izuku's footsteps, Nezu’s ears twitched. He set the tablet down, his black, beady eyes locking onto his little brother. The hyper-intelligent mammal’s face broke into a wide, impossibly sharp smile. 

"Ah! Izuku! Welcome back to our humble abode," Nezu chirped, his voice smooth and sophisticated. "I was just reviewing the yearly budget allocations for the Hero Public Safety Commission. Did you know they tried to hide a three percent reduction in U.A.'s support gear funding under the guise of 'municipal tax restructuring'? Oh, the lengths humans will go to for a few extra yen! I had to send them a very polite email detailing twelve different ways I could bankrupt their pension funds by Tuesday."

Nezu took a delicate sip of his tea. "They reinstated the funding within four minutes. Quite the personal best!"

Izuku smiled weakly, dropping his heavy backpack onto the floor. "That's great, Nezu. I'm glad you're keeping them on their toes."

Nezu’s keen eyes, capable of analyzing micro-expressions in a fraction of a second, immediately noticed the subtle droop in Izuku’s shoulders. His gaze flicked to the scorched, wet ruin of the notebook clutched in Izuku’s hand. He then noticed the distinct burn mark on the shoulder of the school blazer. 

The temperature in the room seemed to drop by ten degrees. 

Nezu placed his teacup onto its saucer. The porcelain made a sharp, definitive clink. 

"Izuku," Nezu said, his cheerful tone vanishing, replaced by something dangerously calm. "Sit down."

Izuku swallowed hard. When Nezu used that tone, it was best to obey. He walked over and sank into the sofa opposite his brother. 

"Your notebook," Nezu stated, his eyes locked onto the charred mass. "Volume Thirteen. The one detailing the structural weaknesses of active Pro Heroes. Destroyed by heat and explosive force. And your uniform. Singed. The burn radius and chemical residue—even from here, I can smell the oxidized glycerin."

Nezu interlaced his paws, resting his chin upon them. He looked less like a school principal and more like an apex predator contemplating its prey. 

"Katsuki Bakugo," Nezu deduced effortlessly. "He assaulted you."

"It wasn't an assault," Izuku tried to defend, though his voice wavered under his brother's intense gaze. "He just... he got mad. He found out I was still applying to U.A. for the hero course. He blew up the notebook and tossed it out the window into the koi pond."

Nezu’s ears flattened slightly. "He destroyed private property. He utilized a registered, lethal-grade Quirk outside of sanctioned zones. He directed a physical attack against an unresisting minor. Legally speaking, Izuku, that is three felonies." 

"Nezu, please, just leave it," Izuku sighed, running a hand through his messy green curls. "It's fine. I'm used to it. The teachers don't care, and if we make a big deal out of it, it's just going to cause more problems. I don't want to ruin his life."

"He ruined your notebook," Nezu pointed out, his tone perfectly level. "A notebook that I helped you compile. That is an insult to both your hard work and my tutelage."

"I have the backups. I just... I'm done with Aldera anyway. I was going to ask if I could finally take you up on that offer for online schooling. I don't want to go back there."

Nezu’s eyes narrowed to tiny, black slits. He leaned forward. "Izuku. Look at me."

Izuku looked up.

"You are my little brother," Nezu said, his voice dropping an octave, carrying a terrifying weight. "You are the son of the woman who pulled me from an alleyway, stitched my wounds, and gave me a name when the rest of humanity viewed me as a dissection subject. You are the most important human in my existence. If Katsuki Bakugo merely burned your book and yelled at you, I might have simply arranged for his U.A. application to be misplaced in a shredder. But there is something else. Your heart rate is slightly elevated. Your cortisol levels, judging by your micro-perspiration, spiked significantly today. What else did he say to you?"

Izuku froze. He knew he shouldn't say it. He knew exactly what it would unleash. But keeping a secret from High Spec was mathematically impossible.

"He... he was just trying to show off in front of his friends," Izuku mumbled, looking down at his lap. "He told me not to apply to U.A. He said... he said if I wanted a Quirk that badly, I should take a swan dive off the roof of the school and pray I'm born with one in the next life."

Silence.

Absolute, suffocating silence. 

Izuku dared to peek up. Nezu had not moved a muscle. His face was a blank, unreadable mask. But the aura radiating from the small creature was so densely packed with bloodlust that it felt as though gravity in the room had doubled. 

"I see," Nezu whispered. 

He didn't yell. He didn't throw his tea. He simply reached into his vest pocket, pulled out a sleek, black smartphone, and tapped the screen three times.

"Nezu, what are you doing?" Izuku asked, panic edging into his voice. "Don't kill him! Mom will be so mad if you kill someone!"

"I am not going to kill him, Izuku," Nezu replied, his thumb flying across the screen at inhuman speeds. "Death is a release. Death is a mercy. Katsuki Bakugo does not deserve mercy. He is a child who has been taught by a corrupt system that his Quirk makes him a god. I am simply going to remind him, and the institution that fostered his delusion, that there are beings in this world far above gods."

Nezu pressed the phone to his ear. It rang once. 

"Ah, Tsukauchi, my good friend!" Nezu said, his voice instantly reverting to its cheerful, polite cadence, though his eyes remained utterly dead. "Yes, good evening. I am going to need you to dispatch a team of financial auditors, three federal investigators, and your best Quirk-counseling psychologists to Aldera Junior High. Yes. First thing tomorrow morning."

Izuku buried his face in his hands. Oh, Kacchan. I told you to be careful.

"Why? Oh, simply put, I have reason to believe the institution is entirely compromised," Nezu continued happily. "Falsified grading for Quirk-favored students, gross negligence regarding bullying and Quirk misuse, and oh, look at this..." Nezu tapped on his tablet with his free hand. "It seems their Principal has been embezzling school funds to pay for a private mistress in Roppongi. Yes, I just hacked his bank accounts. I’ll send you the ledger."

Nezu paused, listening to the stunned detective on the other end. 

"I want the school shut down, Tsukauchi," Nezu said, his tone turning into cold steel. "I want the principal's license revoked. I want every teacher who turned a blind eye blacklisted from the education board. And I want Katsuki Bakugo placed under immediate psychological evaluation by the Hero Commission. Yes. I'll send over the paperwork in ten minutes. Thank you, Detective. Have a lovely evening."

Nezu hung up the phone and placed it gently on the table. He picked his tea back up, his cheerful demeanor completely restored. 

"Now," Nezu smiled at Izuku, "I believe Mom said dinner is in an hour. Katsudon, I hope! And tomorrow, we shall go shopping for a new laptop for you. If you are to begin your online schooling at U.A., you will need hardware capable of processing my encryption algorithms."

Izuku stared at his brother. In less than sixty seconds, Nezu had dismantled an entire school administration and derailed the life of his primary tormentor, all without spilling a drop of his tea.

"You're terrifying," Izuku said, a mixture of awe and exasperation in his voice.

Nezu chuckled, a soft, chittering sound. "I am simply protective, Izuku. The world will learn soon enough: they can try to test me, they can try to cage me, but if they touch my family, I will burn their society to the bedrock." 

Forty-Eight Hours Later

The morning news cycle was dominated by a single, explosive story.

"Breaking News: Aldera Junior High Shut Down Following Massive Corruption and Negligence Probe."

The news helicopter footage showed federal agents carrying boxes of files out of the school building. The Principal, sweating profusely and hiding his face behind a briefcase, was being escorted into a police car. Teachers were standing outside the gates, looking shell-shocked as officials handed them termination notices.

Izuku sat at the kitchen island of their apartment, eating a bowl of rice and natto, watching the television with morbid fascination. 

"Goodness," Inko said, pouring a cup of coffee. She glanced at the screen, then shot a knowing, slightly reprimanding look at the empty armchair in the living room where Nezu usually sat. "I suppose that's what happens when people forget their manners."

Izuku nearly choked on his rice. His mother’s ability to casually brush off her adopted son’s terrifying displays of power would never cease to amaze him.

Meanwhile, across town in a sterile, white-walled interview room at the local precinct, Katsuki Bakugo was experiencing the worst day of his life. 

He was sitting rigidly in a metal chair, his hands bound by specialized Quirk-suppressing cuffs. Across the table sat Detective Naomasa Tsukauchi, looking incredibly tired. Next to Tsukauchi, perched on a stack of phone books to reach the table's height, was a small white creature in a pristine suit. 

Bakugo stared at the rat, his mind reeling. He had been pulled out of bed at six in the morning by police officers. His parents were outside, arguing with lawyers. He had been told his school was shut down, his teachers were fired, and his permanent record was currently under review by the Hero Public Safety Commission. 

"I don't understand," Bakugo growled, his voice tight with barely contained panic and rage. "What the hell is going on? Why am I here?! I didn't do anything!"

"Lie," Tsukauchi sighed, looking at his notes. "Katsuki, my Quirk is a lie detector. Please do not make this harder than it has to be."

"You blew up a peer's personal property, used a lethal Quirk to intimidate, and encouraged a fellow student to commit suicide," Principal Nezu said cheerfully, pouring himself a cup of tea from a thermos he had brought along. "I would hardly call that 'nothing', Mr. Bakugo."

"Who the hell are you?!" Bakugo snapped, straining against the cuffs. "Some kind of talking rat?!"

Tsukauchi flinched. "Bakugo, be quiet. That is the Principal of U.A. High School."

The blood drained from Bakugo’s face. He froze, his crimson eyes widening to the size of saucers. U.A. High. The dream. The goal. The only school that mattered. The Principal was sitting right in front of him. 

"P-Principal?" Bakugo stammered, his arrogance evaporating in an instant. "I... I'm applying to your school. I'm going to be the number one—"

"You are currently applying to a juvenile detention center, Mr. Bakugo," Nezu interrupted, his voice light but cutting like a scalpel. He took a sip of tea. "Let us be unequivocally clear. I despise bullies. I despise individuals who believe that genetic superiority grants them the right to trample upon the weak. You are a textbook narcissist with severe violent tendencies."

Nezu placed the teacup down and leaned forward, his black eyes locking onto Bakugo's. For the first time in his life, Katsuki Bakugo felt something he had never felt before: absolute, primal prey-fear. 

"And above all else," Nezu whispered, his voice dropping into a guttural, terrifying register, "I despise those who threaten my little brother."

Bakugo’s breath hitched. Little brother? His mind raced, flashing back to the green-haired, freckled face of the boy he had tormented for years. The boy who had looked at him with pity just two days ago. Deku. Deku is his brother?!

"You told Izuku Midoriya to jump off a roof," Nezu stated, the room’s temperature seeming to plummet. "For that comment alone, I could ensure you never step foot in a hero academy anywhere on the globe. I could ensure you spend the rest of your life flipping burgers, watching the people you deem 'extras' soar above you."

Bakugo was shaking. He couldn't stop it. The sheer, crushing weight of the creature's intellect and power was suffocating him. "I... I..."

"However," Nezu said, abruptly leaning back and smiling cheerfully, the oppressive aura vanishing in an instant. "Izuku is remarkably kind. He explicitly asked me not to ruin your life. He believes, for some unfathomable reason, that you have the potential to be a true hero. I disagree, but I will defer to his judgment. For now."

Nezu pushed a thick manila folder across the table. 

"Here are my terms, Mr. Bakugo. You are hereby placed on a strict probationary watch list. You will attend mandatory psychological counseling and anger management therapy three times a week. Your Quirk usage outside of heavily monitored, sanctioned training will result in immediate disqualification from any hero track. If you manage to complete these requirements, and if you can pass the U.A. entrance exam—which I assure you, will not be graded favorably for you—you will be allowed to enroll. But you will be on a zero-tolerance policy. One misstep, one display of your previous behavior, and you will be expelled. Do we have an understanding?"

Bakugo stared at the folder. His pride was shattered. His worldview, built upon the foundation of his own invincibility, had been utterly demolished by a creature that barely came up to his knee. He swallowed the lump in his throat, his eyes stinging with humiliating tears he refused to shed.

"Yes," Bakugo whispered, looking down at his lap. "I understand."

"Excellent!" Nezu clapped his paws together. "I look forward to seeing if you can rise above your own abhorrent nature. Have a pleasant day, Mr. Bakugo."

Nezu hopped down from the chairs, tipped an imaginary hat to Tsukauchi, and strolled out of the interrogation room, leaving a thoroughly broken bully in his wake.

Two Weeks Later

The massive gates of U.A. High School loomed tall and imposing, a testament to the prestige and security of Japan’s premier hero academy. 

Izuku Midoriya stood before the biometric scanners, dressed not in a middle school uniform, but in a comfortable green hoodie, dark jeans, and his signature red sneakers. He held a customized U.A. ID card in his hand. 

He swiped the card. 

"Identity Confirmed. Midoriya, Izuku. Security Clearance: Level 9. Welcome back, Prince of U.A." 

Izuku groaned, burying his face in his hands as the robotic voice echoed across the courtyard. "I told him to change that audio file," he muttered, stepping through the gates. 

Life had changed drastically in the past two weeks. With Aldera shut down and his online schooling approved, Izuku’s daily routine now consisted of spending his days within the fortified walls of U.A. He was given a permanent desk in the faculty office, a high-end customized laptop courtesy of the U.A. Support Department, and uninhibited access to the school's training facilities and libraries. 

He walked through the pristine halls, heading toward the staff room. As he passed the open door of a classroom, a loud, booming voice called out to him.

"Heeey! Little Listener!" 

Pro Hero Present Mic slid out into the hallway, striking a dramatic pose. "How's the coolest kid in the building doing today? Got those sick beats I asked you to analyze?"

Izuku smiled brightly. "Hey, Yamada-sensei. Yeah, I emailed you the file this morning. If you adjust the frequency output of your directional speakers by 2.4 kilohertz, you can induce temporary vertigo in villains without causing permanent eardrum damage. It's much more efficient for crowd control."

Mic pulled off his sunglasses, his eyes widening. "You figured that out just by looking at my support gear schematics?" He ruffled Izuku’s green hair. "You're a terrifying little genius, you know that? Just like your bro!"

"Don't inflate his ego, Hizashi," a tired, gruff voice muttered. 

Pro Hero Eraserhead, Shota Aizawa, slouched out of the staff room, holding a brightly colored jelly pouch. He looked as exhausted as ever, his capture weapon hanging loosely around his neck. He peered down at Izuku with half-open eyes. 

"Midoriya," Aizawa grunted. 

"Good morning, Aizawa-sensei," Izuku bowed politely. 

Aizawa sighed, leaning against the wall. "Your brother dumped the curriculum planning for the new first-years on my desk this morning. He said you helped him optimize the physical conditioning parameters. Tell me the truth, kid. Did you suggest the three-mile weighted run, or did he?"

Izuku rubbed the back of his neck sheepishly. "Well... technically, based on muscle-fiber degradation rates, a three-mile run is the most efficient way to build baseline stamina before Quirk training. So... I might have suggested it."

Aizawa stared at him for a long, agonizing moment. Then, surprisingly, a small, terrifying smirk tugged at the corner of his mouth. 

"Logical. Brutal, but logical. I like it," Aizawa said, taking a sip of his jelly pouch. "Just don't tell the other teachers. They already think I'm a sadist. If they find out the Principal's Quirkless little brother is the one designing the torture methods, they'll lose their minds."

"My lips are sealed, Sensei," Izuku promised. 

"Good kid," Aizawa muttered, turning to walk down the hall. "Go to the office. Nemuri baked cookies, and if you don't eat them, she'll force-feed them to me."

Izuku chuckled and made his way to the staff room. Pushing the door open, he was immediately greeted by the smell of vanilla and chocolate chips. Pro Hero Midnight, Nemuri Kayama, was sitting at her desk, painting her nails.

"Izuku!" Midnight cooed, abandoning her polish to rush over and pinch his cheeks. "There's my favorite boy! How are the online classes coming? Are you eating enough? You look skinny. Have a cookie." She shoved a massive chocolate chip cookie into his hand before he could even answer.

"Thanks, Kayama-sensei," Izuku mumbled through a mouthful of cookie. "Classes are fine. I'm finishing up the second-year college calculus module today."

"So smart," she beamed. "Nezu is in his office, by the way. He said he wanted to see you as soon as you arrived. Something about a special guest coming in for a meeting."

Izuku swallowed his bite of cookie, intrigued. "A special guest? Did he say who?"

"Nope," Midnight shrugged. "But he had me clear his schedule for the entire morning, and he ordered the imported Chinese Oolong tea. So it must be someone important."

Izuku nodded, thanking her for the cookie, and made his way to the back of the staff room, toward the large, imposing oak doors that led to the Principal's office. He knocked twice, a specific, syncopated rhythm that he and Nezu used to identify each other. 

"Come in, Izuku!" Nezu's cheerful voice called from within. 

Izuku opened the door and stepped into the massive, elegantly furnished office. Bookshelves lined the walls, filled to the brim with texts ranging from ancient philosophy to advanced cybernetics. Behind a large mahogany desk sat Nezu, currently pouring hot water into a delicate ceramic teapot. 

"Good morning, Nezu," Izuku said, taking his usual seat in the comfortable armchair opposite the desk. He pulled his laptop from his bag and set it down. "Midnight said you were expecting someone important?"

"Indeed I am," Nezu smiled, his eyes glinting with a secret amusement. "Someone very important. In fact, he should be arriving right about..."

Before Nezu could finish his sentence, the heavy oak doors of the office swung open. 

A massive, towering figure stood in the doorway. He was so large he had to duck his head to enter. He wore an oversized, pinstriped yellow suit, and his face was gaunt, with sharp, angular features and deeply sunken blue eyes. He looked sickly, frail, and entirely unassuming.

But Izuku Midoriya was not easily fooled. He had spent his entire life analyzing heroes. He had studied posture, bone structure, and the subtle ways people carried themselves. He had filled thirteen notebooks with data, and his brain, honed by the smartest creature on Earth, made the connection in a fraction of a second. 

Izuku dropped his cookie onto the carpet. 

"Oh my god," Izuku whispered, his emerald eyes wide with absolute shock. He looked from the frail, skeletal man, to his brother, and back again. 

The skeletal man coughed into his hand, a small spatter of blood appearing on his palm. He wiped it away with a handkerchief and offered a sheepish, apologetic smile. "Ah, apologies for the intrusion, Principal Nezu. I hope I am not interrupting."

"Not at all, Yagi-san!" Nezu beamed, gesturing to the empty chair next to Izuku. "Please, take a seat. I was just having morning tea with my little brother."

Izuku couldn't breathe. His mind was racing at a million miles an hour. Blonde hair. Blue eyes. The specific slump of the shoulders designed to hide massive muscle mass atrophy. The left-side injury reported during the toxic chainsaw fight five years ago... no, the timeline doesn't match, it must have been a covered-up fight. A fight with a villain capable of inflicting permanent, debilitating organ damage.

Toshinori Yagi sat down heavily in the chair, letting out a long, exhausted sigh. He glanced at the green-haired boy staring at him with wide, calculating eyes. 

"Ah, hello there, young man," Toshinori said kindly. "I didn't realize the Principal had a brother."

"Toshinori," Nezu said, pouring a cup of tea and sliding it across the desk. "Allow me to introduce you to Izuku Midoriya. Izuku, this is Toshinori Yagi. You may know him better by his professional title."

Izuku finally found his voice. It came out as a breathless, awed squeak. 

"All Might."

Toshinori flinched, looking panicked. He turned to Nezu. "Sir! I thought my true form was a closely guarded secret! You told him?!"

"I told him nothing," Nezu said proudly, taking a sip of his tea. "Izuku figured it out all on his own. He is quite the analyst. In fact, Toshinori, he is the very reason I called you here today."

Nezu steepled his paws together, a predatory, calculating gleam in his eyes. 

"You are here because you are looking for a successor to your Quirk," Nezu stated bluntly. "And I believe, unequivocally, that the boy sitting next to you is the only logical choice."

Izuku’s jaw dropped. Toshinori choked on his tea. 

The game had begun. And in Nezu's office, the rat always played to win.

The silence that blanketed Principal Nezu’s office was absolute, save for the rhythmic, metallic tick-tick-tick of the chimera’s gold pocket watch. 

Toshinori Yagi, the man known to the world as the indomitable Symbol of Peace, sat frozen in his plush armchair. The teacup in his oversized, skeletal hand trembled slightly, a single drop of imported Chinese Oolong splashing over the porcelain brim and staining his yellow pinstriped trousers. He did not notice. His sunken, shadow-draped blue eyes were fixed entirely on the fourteen-year-old boy sitting across from him.

Izuku Midoriya looked equally petrified, though for entirely different reasons. His face was flushed crimson, and his hands were gripping his knees so tightly his knuckles were white. He had just dropped a cookie on the Principal’s antique Persian rug. 

"I... I..." Toshinori stammered, a thin trickle of blood escaping the corner of his mouth. He hurriedly wiped it away with the back of his hand. "Principal Nezu. Sir. Is this some kind of jest? Because if it is, I must admit, I find it highly irregular. My true form is a state secret, known only to a fraction of the Hero Public Safety Commission, my closest associates, and the faculty here at U.A. How could a middle schooler possibly know—"

"I didn't tell him, Toshinori," Nezu interrupted cheerfully, taking a slow, appreciative sip of his tea. "I assure you, I uphold my non-disclosure agreements with the utmost severity. Izuku deduced your identity, your condition, and the nature of your Quirk entirely on his own. In fact, he had it mapped out roughly... oh, when was it, Izuku? Last Tuesday?"

"Wednesday," Izuku squeaked, his voice cracking. He swallowed hard, trying to force his heart back down out of his throat. "It was Wednesday evening. After dinner."

Toshinori stared at the boy. "You... you deduced it. From what? A leak? A hacked database?"

"No," Izuku said softly, his natural, analytical instincts slowly overriding his sheer panic. His eyes darted to his backpack, where his newly started Hero Analysis for the Future No. 14 rested. "From video footage. Publicly available broadcasts. And physics."

Toshinori leaned forward, the skeletal frame creaking slightly. "Explain."

Izuku took a deep breath. Nezu gave him an encouraging nod. 

"Well," Izuku began, his voice gaining traction, the familiar rush of analytical hyper-focus pushing the anxiety to the back of his mind. "It started with your center of gravity. Five years ago, your combat posture shifted. You used to lead heavily with your left side, utilizing a southpaw stance for your Detroit Smashes to maximize torque. But after a completely undocumented absence of three months—which the media attributed to a 'secret overseas mission'—you returned and suddenly began fighting orthodox. You favored your right side. You subtly protected your left abdomen in close-quarters combat."

Toshinori’s eyes widened. "You noticed a slight change in my stance from television broadcasts?"

"It wasn't just the stance," Izuku continued, his hands moving as he spoke, tracing invisible diagrams in the air. "It was the atmospheric pressure. When you execute a Smash, the barometric pressure in a localized radius shifts dramatically due to the sheer kinetic force displacing the air. I wrote an algorithm to measure the wind velocity of your punches based on the structural damage of the surrounding debris. Five years ago, your output dropped by approximately fifteen percent. You compensated by smiling wider and acting more boisterous to distract the public, but the numbers don't lie. You suffered a catastrophic, debilitating injury to your left respiratory and digestive systems five years ago."

Silence returned to the room. Toshinori looked as though he had been struck by a physical blow. 

"And the Quirk?" Toshinori whispered, his voice hoarse. "How could you possibly know about the nature of my Quirk?"

"That... that was harder," Izuku admitted, rubbing the back of his neck sheepishly. "Your Quirk is registered as 'Superpower.' But that's a biological impossibility. A Quirk is a physical appendage or a localized genetic mutation. If you were born with a Quirk that granted you the raw power to change the weather with a punch, the secondary mutations required to keep your bones from shattering and your muscles from tearing would have been apparent from birth. But you didn't debut until you were eighteen. There's no record of you using your Quirk in junior high or early high school."

Izuku leaned forward, his emerald eyes burning with an intense, terrifying intellect that looked remarkably similar to the creature sitting behind the desk. 

"Energy cannot be created or destroyed, All Might. It can only be transferred," Izuku said softly. "Your power doesn't act like a biological mutation. It acts like a stockpiled reserve. A crystalline accumulation of kinetic energy. And given your current physical deterioration, you are running out of that energy. The vessel is broken, and the water is leaking out. Therefore, 'Superpower' is not an inherent trait. It is a transferable torch. And you are here at U.A. because your flame is going out, and you are desperately looking for someone to pass it to."

When Izuku finished speaking, the only sound in the room was the gentle bubbling of the hot water kettle on Nezu's desk. 

Toshinori Yagi sat back in his chair, completely devoid of words. He looked at the green-haired boy, really looked at him, and saw not just a fanboy, but a mind of terrifying, world-shaking caliber. He had spent years keeping his secrets, building a fortress of lies to maintain the Symbol of Peace, and this fourteen-year-old child had dismantled it from his living room sofa with a laptop and a basic understanding of aerodynamics. 

"I..." Toshinori ran a skeletal hand down his face, a hollow, breathless chuckle escaping his lips. "I am completely terrified of you, young man."

"Oh, he gets that a lot," Nezu chimed in happily. "High Spec is an incredible Quirk, you see, but it is entirely useless without a sponge to absorb the knowledge it produces. Izuku is my sponge. I have spent the last decade teaching him everything I know about tactics, physics, psychology, and analysis. He possesses a cognitive processing speed that rivals some of the most advanced supercomputers in I-Island."

Nezu hopped down from his chair and walked around the desk, standing beside Izuku. He placed a small, white paw on the boy’s knee. 

"Which brings us to the crux of this meeting, Toshinori," Nezu said, his cheerful demeanor hardening into a serious, business-like edge. "You came to my school to find a successor. You asked me to keep an eye on Mirio Togata in the third year, and while Mirio is an exceptional candidate with a wonderful heart, I have a counter-proposal. I want you to give your Quirk to my brother."

Izuku’s head snapped toward Nezu. "Wait, what?! Nezu, no! I can't—"

"Quiet, Izuku. Let the adults speak," Nezu said gently, though it brooked no argument. He looked up at the skeletal man. "Izuku has the mind of a master tactician. He possesses a heart that is unfailingly, almost irrationally, selfless. He has spent his entire life studying heroism from an objective, analytical standpoint. He knows the weight of power, because he has lived in the shadow of mine, and he has lived under the heel of those who abuse theirs."

Toshinori looked deeply conflicted. He gripped the armrests of his chair. "Principal Nezu... I do not doubt the boy's intellect. He is, frankly, a genius. But you know the requirements of One For All. It is a stockpiled power of immense, devastating physical weight. A vessel must be forged to hold it."

"Izuku can be trained. He is fourteen. The U.A. entrance exams are ten months away," Nezu countered smoothly. 

"But he is Quirkless!" Toshinori argued, his voice rising in distress. He looked at Izuku with a pained expression. "Young Midoriya, please understand, I am not saying this to be cruel. But the reality of villainy in this world is brutal. If you give a Quirkless body a power this explosive, the backlash alone could blow your limbs clean off! A Quirked individual already has baseline physical enhancements to accommodate their own power. A Quirkless body is a fragile thing. To step into the ring with villains... it's a death sentence. Mirio Togata already has a strong, hardened body and a Quirk that grants him evasion. He is safe."

"Safe," Nezu repeated, tasting the word as if it were a foul piece of meat. "Toshinori, do you honestly believe the Symbol of Peace was built on being safe?"

Toshinori flinched. 

"Mirio Togata is a fine hero. But he fights with instinct," Nezu pressed, stepping closer to All Might. "Izuku fights with calculation. If you give this boy your power, he won't just punch harder. He will punch smarter. He will revolutionize the very foundation of what it means to be a hero. He won't just be the Symbol of Peace, Toshinori. He will be the Architect of it."

Izuku sat perfectly still, his heart hammering against his ribs like a trapped bird. He felt a profound sense of whiplash. One moment, he was a Quirkless nobody whose only friend had told him to jump off a roof. The next, the smartest being on the planet was advocating for him to inherit the power of a living god. 

"I... I can't," Izuku whispered, the words tumbling out before he could stop them. 

Both Nezu and Toshinori looked at him. 

Izuku clenched his fists, staring down at his red sneakers. "All Might is right, Nezu. I'm... I'm Quirkless. I don't have the baseline durability. And even if I did, I don't have battle instincts. I just have notebooks. I write things down. I run numbers. But when a villain attacks... when people are dying... a hero has to act without thinking. They have to throw themselves into the fire. I'm just the guy who calculates the temperature of the flames."

Izuku stood up, grabbing his backpack. He couldn't look All Might in the eye. He felt overwhelmingly ashamed. He felt like a fraud sitting in this room, pretending he was worthy of a power that had safeguarded the world. 

"Thank you for considering me, All Might," Izuku bowed deeply, his voice trembling. "And Nezu... thank you for believing in me. But I need some air."

Without waiting for a response, Izuku turned and practically fled from the office, the heavy oak doors shutting behind him with a resonant thud. 

In the office, Toshinori let out a heavy sigh, running a hand through his messy blonde hair. "Principal Nezu... I am sorry. He is a brilliant boy, but he lacks the raw, unthinking drive. He thinks too much. A hero's body must move before their mind can process the danger."

Nezu simply walked over to the dropped chocolate chip cookie on the floor, picked it up, and tossed it into the wastebasket. He didn't look angry. If anything, he looked amused. 

"Toshinori," Nezu said softly, walking back to his desk and opening his laptop. "You are an exceptional hero, but a terrible judge of psychology. Izuku does not lack the drive. He simply lacks the catalyst. He has been told his entire life that his body is useless. Give him a situation where his mind alone isn't enough, and you will see exactly what my brother is made of."

Nezu typed a few commands into his terminal. A map of Musutafu appeared on the screen, detailing real-time police dispatcher frequencies and traffic cameras. 

"I am going to send Izuku on an errand into the city," Nezu said without looking up. "A mundane task. Picking up a specialized, custom-ordered ergonomic keyboard from a tech shop in the Tatooin Shopping District. I suggest you follow him, All Might. In your true form, of course."

Toshinori frowned. "Why?"

Nezu finally looked up, his black eyes glinting with a dangerous, omniscient light. "Because, according to the local police scanners, a minor villain made entirely of fluid sewage just evaded capture down the street from that very shopping center. The probability of an intersection is approximately eighty-two percent. Go, Toshinori. Watch my brother work."

The streets of the Tatooin Shopping District were bustling with afternoon foot traffic. The sky was overcast, casting a gray pall over the neon signs of the electronics stores and arcades. 

Izuku walked with his head down, the hood of his green jacket pulled up. He had left U.A. shortly after the meeting, wanting nothing more than to lose himself in the anonymity of the crowd. Nezu had sent him a text message asking him to pick up a keyboard, a transparent excuse to get him out of the school and clear his head. 

I'm an idiot, Izuku thought, kicking a stray pebble across the pavement. I've dreamed of having a Quirk my entire life. I've studied All Might for years. And when he's sitting right in front of me, offering me the literal holy grail of Quirks... I run away.

But All Might’s words had struck a deeply insecure chord within him. A Quirkless body is a fragile thing. To step into the ring with villains... it's a death sentence.

Izuku knew he was smart. He knew he could out-think almost anyone his age, and most adults. But intellect couldn't stop a falling building. A mathematical formula couldn't punch a villain in the jaw. And if he took One For All and failed—if his body broke and he died—he wouldn't just be letting himself down. He would be extinguishing the Symbol of Peace. He would be dooming society because he was too selfish to accept his own limitations. 

"Hey, kid, watch where you're going!" a gruff voice snapped. 

Izuku blinked, snapping out of his thoughts just in time to avoid bumping into a large man carrying groceries. "S-Sorry!" Izuku squeaked, bowing quickly. 

He was about to continue toward the tech shop when a massive explosion rocked the street. 

The ground shuddered. Windows on the nearby storefronts shattered, showering the pavement in crystalline rain. Screams erupted from the crowd ahead as a massive plume of thick, acrid black smoke billowed into the gray sky. 

Izuku’s instincts—honed by years of analyzing disaster footage—kicked in instantly. He didn't run away. He ran toward the smoke. 

He pushed his way through the panicking throng of civilians, dodging fleeing pedestrians until he reached the edge of a hastily erected police barricade. Pro Heroes were already on the scene. Death Arms, Kamui Woods, and Mt. Lady were standing near the police tape, looking entirely helpless. 

Beyond them, the street was a war zone. Several buildings were on fire. And in the center of the intersection, thrashing wildly, was a massive, towering monstrosity made of foul-smelling, dark green sludge. 

"It's no good!" Death Arms shouted over the roar of the flames, punching his fists together. "I can't grab him! It's like trying to wrestle a river! I just slip right through!"

"I need at least two lanes for my Quirk!" Mt. Lady complained, looking at the narrow street. "If I grow here, I'll crush the surrounding buildings!"

"And my wood will just catch fire!" Kamui Woods added, shielding his face from the intense heat. "We need someone with a water Quirk, or someone who can blow this guy away!"

Izuku stared at the scene, his mind rapidly processing the data. Villain is comprised of a non-Newtonian fluid. Susceptible to extreme temperature changes or compartmentalization. Currently utilizing a hostage as a meat shield and a weapon source.

Izuku’s eyes zeroed in on the hostage struggling within the suffocating mass of sludge. 

Spiky ash-blonde hair. Crimson eyes wide with unadulterated, choking terror. A hand desperately reaching out, setting off localized, frantic explosions that only served to fuel the fires around them. 

Kacchan.

Izuku’s breath hitched. Bakugo was drowning in the middle of a burning street. And the Pro Heroes were doing absolutely nothing. They were waiting for someone with a 'better Quirk' to arrive. 

A hero's body must move before their mind can process the danger.

Izuku didn't realize he was moving until he felt the yellow police tape snap against his waist. He ducked under it, his red sneakers pounding against the hot asphalt. 

"Hey! Kid! Get back here! Are you crazy?!" Death Arms bellowed, reaching out to grab him, but Izuku was already out of reach. 

Izuku sprinted toward the towering mass of sludge. His mind, unburdened by fear, fell into the icy, hyper-calculated rhythm of High Spec’s tutelage. He wasn't acting on pure instinct. He was acting on accelerated tactical processing. 

Distance: 40 meters. Villain composition: Viscous liquid, likely highly flammable given the smoke output, but currently insulated by its own mass. Weak point: The eyes. The only solid matter on its body.

"What the hell?!" The Sludge Villain roared, its gelatinous eyes swiveling to look at the charging boy. "Another bug to squash! Get lost, kid, before I drown you too!"

Bakugo, half-submerged in the muck, managed to turn his head. His eyes widened in disbelief. "Deku...?" he gurgled, a mixture of shock and fury in his tone. 

Izuku didn't stop. As he reached the ten-meter mark, he swung his backpack off his shoulders. He didn't just throw it blindly. He unzipped the main compartment, reached in, and grabbed a thick, heavy, hardbound book—Hero Analysis for the Future No. 12. 

Using his momentum, Izuku pitched the book with the precision of a major-league pitcher. It wasn't aimed at the villain's mass. It was aimed perfectly, flawlessly, at the creature's massive right eye. 

SMACK.

The hardbound spine connected with a sickening squelch. The Sludge Villain howled in agony, its form rippling and destabilizing as it recoiled. 

"GAAAH! You little brat!"

The flinch loosened the villain's grip on its hostage. Bakugo’s mouth broke free of the sludge, allowing the blonde boy to suck in a desperate, ragged breath. 

Izuku closed the distance, sliding on his knees across the pavement to avoid a sweeping tendril of sludge. He popped up right in front of Bakugo. 

"What the hell are you doing here?!" Bakugo coughed, tears streaming down his face. "You're Quirkless! You can't do anything!"

"I couldn't just sit there and watch you die, Kacchan!" Izuku yelled back, his hands desperately clawing at the sludge surrounding Bakugo’s arms. It was like digging into wet cement. "And I'm not trying to pull you out! I'm trying to create a catalyst!"

"A what?!"

"Your Quirk!" Izuku shouted, dodging another swipe from the blinded, thrashing villain. "You secrete nitroglycerin sweat! The villain is made of a viscous fluid. If I can expose enough of your sweat glands to the open air and you ignite it, the concussive force in a localized bubble will blow him apart without igniting the entire street! But I need to clear your palms!"

Bakugo stared at Izuku, utterly stunned. In the middle of a life-or-death scenario, the "useless" Deku was doing collegiate-level fluid dynamics calculations. 

"Do it!" Bakugo roared, gritting his teeth. 

Izuku plunged his hands deeper into the muck, ignoring the burning, acidic sting on his skin. He found Bakugo’s wrists and hauled with all his might, using leverage and his lower body strength to pry the sludge apart. 

"I'm gonna kill you! Both of you!" the Sludge Villain shrieked, recovering its vision. A massive, tidal wave of muck reared up, casting a massive shadow over the two boys. It was preparing to crush them flat. 

Izuku looked up at the descending wave of death. He had cleared Bakugo’s hands, but he was out of time. The explosion wouldn't be fast enough. He was going to die here. 

But suddenly, a towering silhouette materialized between them and the falling sludge. 

A hand, large and heavily muscled, gripped the fabric of Izuku’s jacket, pulling him backward out of the danger zone. 

"I really am pathetic," a deep, resonant voice boomed, vibrating through the very pavement beneath their feet. 

Izuku gasped, looking up. 

Toshinori Yagi was no longer skeletal. The oversized suit was now stretched taut over a physique that defied human biology. Muscles bulged with terrifying, immense power. The sunken blue eyes were now shielded by heavy brows, radiating an indomitable, shining will. 

All Might had arrived. And he wasn't smiling. He looked furious—at himself. 

"I told you the requirements for being a hero, young man," All Might roared, blood dripping from his lip as he forced his broken body to hold the transformation. "But I failed to live up to my own ideals! Pros are always risking their lives! That is the true test of a hero!"

All Might reared back his right arm. The air around his fist began to warp and distort, pulling the surrounding flames inward like a vacuum. 

"DETROIT..." 

The Sludge Villain panicked, trying to flee. 

"...SMASH!"

All Might threw the punch. He didn't make contact with the villain. He didn't need to. The sheer kinetic force of the strike shattered the air itself. A localized tornado erupted in the middle of the street. 

The wind pressure was catastrophic. The Sludge Villain was instantly vaporized, blown into thousands of tiny, harmless droplets that splattered across the buildings. The fires in the immediate vicinity were snuffed out entirely, starved of oxygen by the vacuum. 

Izuku and Bakugo were sent tumbling backward, shielded only by the massive, immovable back of the number one hero. 

As the wind died down, the sky above them—previously choked with gray clouds and black smoke—split wide open. Sunlight poured through the gap, illuminating the destroyed street. 

It began to rain. All Might had changed the weather with a single punch. 

The silence that followed was deafening. The crowd, the Pro Heroes, and the police all stared in absolute, paralyzing awe. Then, the cheering started. A deafening roar of relief and adulation. 

Izuku sat on the wet pavement, his hands scraped and bleeding, his breathing ragged. He looked up at the towering back of All Might. The Symbol of Peace stood tall, raising a fist to the crowd, but Izuku could see the slight tremor in his legs. He was at his limit. 

"You..." Bakugo rasped, sitting a few feet away. He glared at Izuku, wiping soot from his face. "You didn't save me, Deku. You just got in the way. Don't think for a second I owe you anything. I could have handled it."

Bakugo stood up, ignoring the paramedics rushing toward him, and stomped away, his pride far more wounded than his body. 

Izuku watched him go, a tired, weary sigh escaping his lips. "Yeah. I know, Kacchan."

Before Izuku could stand, Kamui Woods and Death Arms descended upon him. They weren't cheering. They looked furious. 

"What were you thinking?!" Death Arms scolded, pointing a finger in Izuku's face. "You could have gotten yourself killed! There is absolutely no excuse for a civilian—especially a Quirkless kid—to charge into a hostage situation! You endangered yourself and the hostage!"

"He was suffocating," Izuku tried to explain, his voice quiet. "You guys were just standing there. The fluid dynamics of the villain meant brute force wouldn't work. I had to create a catalyst—"

"I don't care about your nerd physics!" Death Arms barked. "Leave hero work to the heroes! You're lucky All Might showed up when he did, otherwise they'd be scraping you off the pavement!"

Izuku looked down at his ruined, bloody hands. The adrenaline was fading, replaced by a cold, hollow shame. He was right. He had been reckless. He had run in without a plan to get out. He wasn't a hero. He was just a liability. 

"I'm sorry," Izuku whispered. 

He didn't stick around for the rest of the lecture. Once the paramedics cleared him of a concussion, Izuku grabbed his ruined backpack, slipped through the crowd, and began the long walk home. 

The sun was beginning to set, casting long, golden shadows across the quiet residential streets of Musutafu. Izuku dragged his feet, his muscles aching with a profound lethargy. He had failed. He had failed All Might’s test, he had failed his own logic, and he had probably embarrassed his brother. 

"I am here!" 

Izuku yelped, nearly jumping out of his skin as All Might suddenly slid out from a nearby alleyway, striking a dramatic pose. 

"All Might?!" Izuku gasped, looking around frantically to see if anyone had noticed the number one hero lurking in an alley. "What are you doing here? How did you get away from the press?"

"Hahaha! Shaking off the press is child's play for me!" All Might boomed. But then, a sudden spasm racked his body. He doubled over, coughing violently. In a puff of steam, the massive, muscular hero deflated back into the skeletal, blood-spitting Toshinori Yagi. 

"Ah... blast it," Toshinori groaned, wiping his chin. "My time limit is getting shorter by the day."

Izuku immediately stepped forward, his analytical mind kicking in. "You pushed yourself too hard. The torque of the Detroit Smash requires your muscular form to brace the skeletal structure. If you force the transformation when your stamina is depleted, you risk micro-fractures in your spine!"

Toshinori looked at the boy, a soft, incredibly fond smile gracing his gaunt features. 

"You really don't stop analyzing, do you, young Midoriya?" Toshinori chuckled. He leaned back against a brick wall, catching his breath. "I came here to find you. To apologize. And to correct a grave mistake I made earlier today."

Izuku looked down. "You don't have to apologize. You were right. I'm Quirkless. I ran in there and almost got killed. The Pros scolded me, and they were right to."

"The Pros are fools," Toshinori said sharply, his tone holding no room for argument. 

Izuku looked up, stunned. 

"If I had not been there, young man, that boy would have died. The Pros stood by and waited for a better opportunity. You—a Quirkless, terrified boy with nothing but a backpack and a brilliant mind—you were the only one who acted." 

Toshinori stepped forward, his blue eyes locking onto Izuku’s emerald ones. The air around them seemed to still. The Symbol of Peace was no longer putting on a show. He was speaking from the very core of his soul. 

"Top heroes have stories about their school days. Most of their stories have one thing in common: their bodies moved before they had a chance to think." Toshinori placed a skeletal hand over his heart. "Today, that happened to you."

Tears pricked the corners of Izuku’s eyes. He had waited his entire life to hear those words. He had analyzed thousands of heroes, read millions of words, and endured endless torment, all while hoping that someday, someone would validate his existence. 

"Your brother was right," Toshinori said, his voice dropping to a reverent whisper. "You do not lack the drive. You simply needed the fire. You didn't just run in blindly, Midoriya. You analyzed the enemy's composition, identified the hostage's Quirk potential, and attempted to orchestrate a tactical extraction under extreme duress. You fought like a tactician. You fought like a true hero."

Toshinori knelt down, bringing himself eye-level with the crying boy. 

"Izuku Midoriya. You can become a hero. I deem you worthy of my power. Will you inherit One For All?"

Izuku couldn't hold it back anymore. The tears spilled over, tracing tracks down his soot-stained cheeks. He fell to his knees, clutching the fabric of his ruined jacket over his chest. He cried for the years of bullying. He cried for his mother's apologies. He cried for the immense, crushing relief that he wasn't useless after all. 

He looked up at the frail man who held the power of a god, and nodded. 

"Yes," Izuku choked out, his voice thick with emotion. "I accept."

Toshinori smiled brightly. "Excellent! It will be a long, arduous road, my boy! Ten months of hellish physical conditioning to forge your body into a vessel capable of holding this power! We will start tomorrow at the municipal beach park—"

"Actually, Toshinori, we will start right now. In the conference room."

Both All Might and Izuku jumped. 

Standing at the entrance of the alleyway, holding a sleek black briefcase and a thermos of tea, was Principal Nezu. He was smiling his terrifying, cheerful smile. 

"Nezu?" Izuku sniffled, wiping his eyes. "How long have you been standing there?"

"Long enough to witness a very touching passing of the torch," Nezu chirped, trotting over to them. He looked up at Toshinori. "I must say, All Might, you made the correct choice. I am very proud of you. And I am incredibly proud of you, Izuku."

Nezu patted Izuku's knee affectionately. Then, he unlatched his briefcase. 

"Now," Nezu said, pulling out a massive stack of papers that looked thick enough to stop a bullet. "As the legal guardian of the minor you are about to bequeath a highly classified, bio-hazardous Quirk to, there are some formalities we must attend to."

Toshinori stared at the stack of papers, a sudden sense of dread washing over him. "Formalities?"

"Oh, yes!" Nezu beamed, pulling a fountain pen from his vest pocket. "This is a fifty-page, legally binding contract detailing your obligations as my brother's mentor. It includes clauses on medical liability, nutritional provisioning, educational integration, and a very specific stipulation regarding your teaching methods. Namely, that I will be overseeing your curriculum to ensure you do not break him."

Nezu handed the heavy stack of papers to the number one hero. 

"Clause 4, subsection B, stipulates that if you cause permanent, debilitating damage to my brother due to reckless training regimens, I am legally entitled to liquidate your hero agency's assets and donate the funds to an animal shelter of my choosing. Sign on the dotted line, please!"

Toshinori Yagi, the Symbol of Peace, the man who had stared down the most terrifying villains in history without blinking, looked down at the smiling white chimera and felt a genuine, cold sweat break out on his neck. 

He had just sold his soul to a rat. 

"I'll... I'll just read this over tonight," Toshinori swallowed hard. 

"Take your time!" Nezu said happily. "We have ten months, after all. Come along, Izuku. Mom is making Katsudon for dinner, and we have a training regimen to optimize!"

Izuku wiped the last of his tears away, a genuine, radiant smile breaking across his face. For the first time in his life, he didn't feel like a side character in his own story. He was Izuku Midoriya. He was the successor to One For All. And he was the little brother of the smartest being in the world. 

He looked at All Might, who was currently reading page three of the contract with a look of mounting horror. 

"Don't worry, All Might," Izuku offered helpfully. "He usually doesn't enforce the asset liquidation clause unless you really mess up."

Toshinori groaned. "What have I gotten myself into?"

"The future," Nezu answered cheerfully, leading Izuku out of the alley. "And I promise you, Toshinori, it is going to be spectacular."

The alarm clock did not stand a chance. 

At exactly 4:00 AM, the digital device on Izuku Midoriya’s nightstand clicked, preparing to emit its shrill, waking buzz. But before the first soundwave could even properly form, a hand shot out from beneath the warm covers. It was not the soft, unblemished hand of a timid middle schooler. It was a hand wrapped in pale, faded scars, the knuckles calloused, the forearms corded with dense, lean muscle. 

Izuku hit the snooze button with the exact amount of pressure required to silence the machine without cracking the plastic casing—a precise 3.2 pounds of force. 

He sat up in the darkness of his bedroom, the cool morning air washing over his bare shoulders. He took a deep, measured breath, letting the oxygen flood his system. Ten months. It had been ten months since the incident with the Sludge Villain. Ten months since All Might had deemed him worthy. Ten months of absolute, unadulterated hell. 

Toshinori Yagi’s "Aim to Pass: American Dream Plan" had been grueling enough on its own—hauling refrigerators, clearing tons of illegal dumping from Dagobah Municipal Beach Park, and physically tearing his muscles down only to rebuild them stronger. But that was only half of the equation. 

Principal Nezu had taken one look at All Might’s training regimen, laughed his terrifying, chittering laugh, and added his own addendum: "The High Spec: Tactical Supremacy Plan." 

While All Might forged Izuku’s body, Nezu weaponized his mind. Izuku had spent his evenings running combat simulations, learning advanced computer cryptography, studying structural engineering, and mastering the psychological art of misdirection. Nezu had taught him how to read a battlefield not as a brawler, but as a grandmaster looking at a chessboard. 

Izuku stood up and walked over to his mirror. He flicked on the light. 

The boy looking back at him was fundamentally different from the one who had cried in an alleyway. He was taller, his posture straight and grounded. The baby fat in his cheeks had burned away, leaving a sharp, focused jawline. But the most significant change was the faint, emerald-green lightning that occasionally sparked across his skin when he flexed his fingers. 

One For All. 

He had only ingested the hair—the DNA vessel of the Quirk—two weeks ago. The sheer, terrifying power of it had nearly blacked him out. Under Nezu’s strict observation, Izuku had bypassed the foolish notion of treating the Quirk like a localized super-move. Nezu had recognized immediately that funneling a century’s worth of stockpiled kinetic energy into a single limb was a mathematical guarantee for shattered bones. 

"A river cannot flow through a straw, Izuku," Nezu had said, watching the boy struggle to channel the power. "You must widen the banks. Do not call upon the power to strike. Call upon it to exist. Wrap it around yourself like a garment."

It had taken weeks of agonizing trial and error, but Izuku had found the sweet spot. Five percent. A full-body distribution of five percent of One For All’s maximum output. He called it Full Cowling. It wasn’t enough to change the weather with a punch, but it was enough to give him superhuman agility, enhanced durability, and a reaction time that paired flawlessly with his hyper-analytical mind.

"Today's the day," Izuku whispered to his reflection. 

He quickly showered, dressed in his customized middle-school uniform—tailored slightly to accommodate his new musculature—and walked out into the living room. 

The smell of freshly grilled salmon, miso soup, and white rice filled the air. Inko Midoriya was already at the stove, humming softly. Sitting at the kitchen island, nursing a cup of Earl Grey tea and reading the morning financial reports on a holographic tablet, was Nezu.

"Good morning, Izuku!" Nezu chirped without looking up. "Your resting heart rate is hovering at a steady sixty-two beats per minute. Excellent. No pre-exam anxiety?"

"A little," Izuku admitted, taking a seat and accepting a bowl of rice from his mother. "But statistically speaking, given my mock exam scores and the physical parameters of the U.A. robotics, my probability of failure is less than 0.04 percent. The anxiety is mostly biological, not logical."

Inko sighed fondly, placing a piece of salmon on his plate. "You boys and your numbers. I'm just so proud of how hard you've worked, Izuku. Just... please don't get hurt. I know your brother is the Principal, but I still worry."

"I'll be fine, Mom. I have my gear."

Nezu tapped his tablet, and the hologram vanished. He reached down beside his stool and lifted a sleek, brushed-steel briefcase, placing it on the counter. It bore the U.A. Support Department insignia. 

"Ah, yes. The gear," Nezu smiled, his black eyes glinting. "Under standard U.A. regulations, examinees are prohibited from bringing outside support items unless they have a registered Quirk handicap. However, since your Quirk status is legally registered as 'Late Bloomer,' and I am the Principal who rewrites the rules as I see fit, your requisition forms were approved."

Nezu pushed the briefcase toward Izuku. "Majima in the Support Lab followed your blueprints to the letter. I must say, incorporating localized electromagnetic dampeners into the gauntlets was a stroke of genius. You are going to give the other examinees quite a complex."

Izuku ran a hand over the cool metal of the case. "I just don't want to rely solely on One For All. All Might hits things. I want to control things."

"And control them you shall," Nezu said, taking a final sip of his tea and hopping down from his stool. "I must be off. I have to oversee the observation room and ensure Shota actually stays awake through the practical. Good luck, little brother. Show them the might of the Midoriya family."

The morning sun reflected off the massive glass towers of U.A. High School. To the thousands of hopeful teenagers streaming through the front gates, it looked like an insurmountable fortress of dreams. To Izuku, it was just the place he had spent every afternoon for the last ten months. 

He navigated the crowd with practiced ease, his briefcase gripped firmly in his right hand. He didn't strut, but he walked with a quiet, undeniable presence that caused people to subconsciously step out of his way. 

"Outta the way." 

A low, gruff voice sounded behind him. Izuku didn't flinch. He recognized the cadence, the heavy footfalls, and the faint smell of burnt sugar. 

Izuku stepped to the side, allowing Katsuki Bakugo to pass. Bakugo looked entirely different from the arrogant boy at Aldera Junior High. The wild arrogance had been beaten down into a simmering, hyper-focused intensity. The probationary rules Nezu had placed upon him, combined with intense anger-management therapy, had not extinguished Bakugo’s fire, but rather compressed it into a laser. 

Bakugo didn't yell. He didn't pop explosions in his palms. He didn't even look Izuku in the eye. He just walked past, his jaw clenched tight enough to crack his teeth. 

He's terrified of making a mistake, Izuku analyzed silently. His cortisol levels are spiking. He knows Nezu is watching his every move. 

Izuku felt a brief pang of sympathy, but he quickly compartmentalized it. Today was not about Kacchan. Today was about passing the exam. 

As Izuku turned his attention back to the massive entrance doors, his foot caught the edge of an uneven paving stone. He stumbled, his center of gravity pitching forward. Instinctively, he sparked One For All to catch himself, but before he could activate it, his body suddenly lost all its weight. 

He floated in mid-air, his limbs flailing slightly in zero gravity. 

"Oops! Sorry about that!" 

Izuku turned his head to see a girl with short, bobbed brown hair and permanent pink blush on her cheeks. She had her hands clasped together, looking slightly panicked. 

"I caught you with my Quirk," she smiled, pressing her fingertips together. Izuku immediately dropped to the ground, landing lightly on his feet. "It's bad luck to fall right before the exam, right? I'm Ochaco Uraraka! Nice to meet you!"

Izuku blinked, his brain immediately categorizing the interaction. Tactile-triggered localized gravity negation. Five pads on each fingertip. She requires all five to make contact for activation. A highly versatile rescue and capture Quirk, though likely hindered by a severe weight limit or nausea drawback given her slight frame.

"Oh, uh, thank you," Izuku bowed politely, his social skills still slightly lagging behind his combat algorithms. "I'm Izuku Midoriya. That's a highly efficient Quirk for debris clearing and vertical mobility."

Uraraka beamed, clearly entirely unbothered by his analytical tone. "Thanks! You look really calm, Midoriya. I'm a nervous wreck! Good luck in there!"

She waved and jogged off toward the auditorium. Izuku watched her go, a small, genuine smile on his face. She's nice.

The written portion of the exam was, frankly, an insult to Izuku’s intelligence. It covered standard high school curriculum—mathematics, Japanese history, English, and basic physics. For a boy who spent his weekends debating quantum mechanics with a hyper-intelligent chimera, it was a warm-up. Izuku finished the two-hour exam in fourteen minutes. He spent the remaining hour and forty-six minutes redesigning the school's HVAC system on the back of his test booklet to optimize airflow in the gymnasium. 

When the bell finally rang, the students were ushered into the massive, stadium-style auditorium for the practical exam orientation. 

Pro Hero Present Mic stood at the DJ podium, attempting to hype up the crowd of thousands of silent, nervous teenagers. 

"WELCOME TO MY LIVE SHOW, EVERYBODY! SAY HEEEY!" 

Silence. 

"Tough crowd! That's fine, I'll just skip to the main event!" Present Mic shouted, pointing at the massive screen behind him. "As your applications stated, you listeners will be conducting a ten-minute urban combat simulation! You can take whatever you want with you! After this presentation, you'll head to your specified battle centers!"

Izuku looked down at his printed ticket. Battle Center B. He glanced subtly to his left, where Bakugo was sitting a few seats away. Bakugo had Battle Center A. Nezu made sure we were separated, Izuku noted. A logical precaution to prevent interpersonal conflict from skewing the grading metrics.

Present Mic continued, explaining the point system. "There are three types of faux villains in every center! They are worth one, two, or three points based on difficulty! Your goal is to use your Quirks to dismantle them and rack up a high score! But remember, no attacking other examinees! That's a red card, baby!"

Suddenly, a tall, broad-shouldered boy with glasses and perfectly combed blue hair stood up from the front row. His arm shot into the air with robotic stiffness. 

"Excuse me! I have a question!" The boy practically shouted. 

"Hit me, examinee number 7111!" Mic pointed. 

"The printout states there are four types of villains, not three!" The boy gestured to the pamphlet. "If this is a misprint, then U.A., the premier hero academy in Japan, should be ashamed of such a careless error! We are here to receive top-tier guidance, not to be subjected to sloppy administration!" 

The boy then turned around, his stern eyes scanning the crowd before locking onto Izuku. 

"And you! The boy with the green hair and the silver briefcase!" 

Izuku blinked, pointing to himself. 

"You have been muttering under your breath this entire time! It is highly distracting!" The boy scolded loudly. "If you are not taking this seriously, then you should leave immediately!"

Several students turned to glare at Izuku. Bakugo, sitting nearby, physically cringed and looked away, recognizing the exact same scenario from Aldera, but knowing precisely how this was going to end. 

Izuku didn't flinch. He didn't cower. He simply pressed a button on the latch of his briefcase, the metallic clack echoing sharply in the quiet auditorium. He stood up, meeting the bespectacled boy's gaze with calm, piercing emerald eyes. 

"I apologize if my cognitive processing was audible and caused you distress, examinee 7111," Izuku said, his voice projecting clearly across the room, carrying the distinct, authoritative cadence of Principal Nezu. "However, if you had properly cross-referenced the tactical layout of the faux villains with standard U.A. testing parameters, you would have already deduced the answer to your question."

The boy with glasses bristled. "Excuse me?"

Izuku raised a finger, stepping out into the aisle. "The printout shows a fourth silhouette. It is significantly larger than the one, two, and three-pointers. Logically, given that this is a test of heroic aptitude, the fourth robot is a field hazard. An obstacle designed not to test our combat prowess, but our situational awareness and threat-avoidance. It is worth zero points because engaging it yields no tactical advantage."

Izuku turned his gaze from the stunned boy up to Present Mic, who was currently grinning like a maniac. 

"Furthermore," Izuku continued smoothly, "questioning the administration's competence before allowing the presiding Pro Hero to finish his presentation is incredibly disrespectful to Present Mic, who has spent the last month carefully calibrating the acoustic dampeners in this very auditorium to accommodate the varying hearing sensitivities of thousands of Quirks." Izuku bowed deeply to the podium. "Please continue, Yamada-sensei."

The entire auditorium was dead silent. The boy with glasses turned beet red, stammered a frantic apology, and practically threw himself back into his seat. 

Present Mic threw his head back and laughed, pointing double finger-guns at Izuku. "EXACTLY RIGHT, LISTENER! YOU NAILED IT! The fourth villain is the Zero Pointer! It's a massive obstacle that goes crazy in narrow spaces! My advice? Run away from it! Now, go beyond! PLUS ULTRA!"

As the students filed out toward the buses, Bakugo walked past Izuku. "Show-off," Bakugo muttered, though there was no real heat in it. 

"Just stating the facts, Kacchan," Izuku replied, a small smirk on his face. 

Battle Center B - The Starting Gates

The towering doors of the mock city loomed over the crowd of examinees. Most of the teenagers were stretching, psyching themselves up, or showing off their Quirks to one another. 

Izuku stood near the back of the pack. He had opened his briefcase and donned his support gear. It wasn't flashy. It was highly utilitarian. He wore a dark green, impact-resistant tactical vest over his uniform. On his forearms were sleek, matte-black gauntlets with small holographic interfaces built into the wrists. Clipped to his belt were several metallic discs and a grapple-line launcher. 

He saw Uraraka nearby, trying to take deep breaths to calm her nerves. He considered approaching her to offer a tactical alliance, but before he could move, the booming voice of Present Mic echoed from the watchtower. 

"START!" 

The examinees hesitated. 

"WHAT'S WRONG? THERE ARE NO COUNTDOWNS IN REAL BATTLES! RUN, RUN, RUN!" 

The crowd surged forward, a stampede of Quirks and adrenaline, rushing straight down the main avenue. 

Izuku didn't run with them. That was a tactical error. Following the herd meant competing for the same limited pool of targets. 

Instead, Izuku calmly walked over to the towering concrete wall enclosing the city. He aimed his wrist, fired his grapple line, and let the motorized winch rip him thirty feet into the air. He landed silently on the roof of a three-story mock apartment building. 

From the high ground, the entire battlefield lay bare before him. 

Green lightning sparked around his body. One For All: Full Cowling - 5%. 

Izuku’s vision sharpened. His brain went into overdrive. He could hear the grinding gears of the faux villains echoing down the alleyways. He could see the dust trails of the one and two-pointers moving toward the sounds of the examinees. 

"Phase One," Izuku whispered. "Establish control."

He leaped off the roof, bounding across the gap to the next building with superhuman grace. He dropped down into a narrow alleyway, landing perfectly behind a squad of three Two-Pointers that were rolling toward the main street. 

The robots spun around, their red optical sensors locking onto him. "TARGET ACQUIRED."

Izuku didn't punch them. He raised his left gauntlet. His fingers danced across the holographic interface at blinding speed, executing a brute-force decryption algorithm he had written himself. The gauntlet emitted a localized electromagnetic pulse. 

The three Two-Pointers froze, their red eyes flickering to a docile blue. 

Izuku tapped his gauntlet. "Override successful. Command authorization: Midoriya. Directives: Engage all hostile units bearing red optical sensors. Defend all biological entities."

The three robots whirred to life and immediately rolled past Izuku, heading into the fray to fight their own kind. 

"Six points," Izuku noted, launching his grapple line and swinging up to the fire escape. 

For the next seven minutes, Izuku Midoriya did not fight a single battle. He orchestrated a war. 

He moved like a ghost through the upper echelons of the city. He used his explosive speed to outflank groups of robots, utilizing his hacking gauntlets to turn Three-Pointers into his own personal artillery. He set up tripwires in narrow chokepoints, funneling dozens of One-Pointers into dead ends where his hijacked robots would decimate them. 

When he encountered other examinees struggling, he didn't swoop in for the kill-steal. He used his captured robots to draw aggro, allowing the other students to score points while he silently moved on. 

He was treating the U.A. Entrance Exam like a real-time strategy game. And he was winning by a landslide. 

The Observation Room

Deep within the bowels of the U.A. administration building, a wall of massive, high-definition monitors displayed the chaos of the various battle centers. 

The faculty of U.A. High School sat in comfortable leather chairs, analyzing the hopefuls. 

Pro Hero Snipe nodded approvingly at a screen showing Bakugo violently dismantling robots. "That kid in Center A is a powerhouse. Raw instinct. A bit aggressive, but his combat viability is off the charts."

"He lacks finesse," Midnight commented, crossing her legs. "But that explosion Quirk is undoubtedly flashy."

In the center of the room, sitting on a custom-built high chair, Principal Nezu was happily sipping his tea. Standing right beside him, wrapped in his yellow sleeping bag, was Eraserhead. 

"Shota," Nezu purred, not taking his eyes off a specific monitor. "What do you think of examinee number 7112?"

Aizawa unzipped his sleeping bag slightly, his bloodshot eyes narrowing as he looked at the screen Nezu was pointing at. It was the feed for Battle Center B. 

The other teachers eventually followed their gaze, and a stunned silence fell over the room. 

The screen showed Izuku Midoriya standing on a rooftop. Below him, a literal army of hacked U.A. robots were forming a defensive perimeter around a group of exhausted examinees, fighting off a wave of Three-Pointers. Izuku was directing them with precise hand signals, his face calm, analytical, and completely unbothered. 

"What in the world..." Pro Hero Ectoplasm muttered. "Is his Quirk technopathy? He's completely overridden the mainframe of our robots. The firewalls on those machines are military-grade!"

"No," Nezu chuckled, his tail swishing behind him. "His Quirk is not technopathy. He simply wrote a better decryption code than Majima did. And he did it on a Tuesday afternoon while watching a documentary on honey badgers."

Aizawa groaned, pinching the bridge of his nose. "Nezu. Tell me you didn't."

"Didn't what, Shota?" Nezu asked innocently. 

"Tell me you didn't train a successor," Aizawa said, a profound weariness in his voice. "We already have to deal with you hacking the government for fun. Now you've created a Mini-Nezu who also has... what is that? Enhanced mobility? Super strength?"

"Oh, he's much more than a Mini-Me," Nezu smiled, his eyes glinting with immense pride. "He is Izuku Midoriya. My little brother."

The collective gasp from the faculty was audible. Midnight nearly dropped her clipboard. "Wait... the kid you're always talking about? The one who redesigned my costume's weave structure to be tear-resistant? That's him?!"

"The very same," Nezu beamed. "And look at him go! Seventy-four villain points, and an estimated forty rescue points from providing covering fire for his peers. He hasn't thrown a single punch."

"He's terrifying," Snipe whispered, adjusting his mask. "He's not fighting the exam. He broke it. He's commanding the battlefield."

"Indeed," Nezu placed his teacup down. He reached forward and slammed his paw onto a large red button on the console. "But true heroes do not merely command from the shadows. Let us see how he handles a disruption to his perfectly laid plans. Deploy the hazards."

Battle Center B

"TWO MINUTES REMAINING!" Present Mic's voice blared across the city. 

Izuku was currently re-wiring a downed Three-Pointer's optical sensor to act as a wide-range radar ping when the ground beneath his feet violently lurched. 

It wasn't an explosion. It was a localized earthquake. 

Izuku dropped his tools, his eyes snapping toward the center of the mock city. The towering skyline of fake buildings was suddenly eclipsed by something far larger. 

The Zero Pointer. 

It was a mechanical titan, a towering behemoth of steel, treads, and red glowing eyes. It crushed a four-story building beneath its tracks as if it were made of wet cardboard. A massive shockwave of displaced air and dust swept through the streets, knocking several examinees off their feet. 

Panic immediately set in. The teenagers, who had been confidently smashing smaller robots seconds ago, turned and fled in absolute terror. 

"Run! That thing's huge!"

"It's the Zero Pointer! Mic said to avoid it!"

Izuku stood his ground on the trembling street. His analytical mind immediately began running threat assessments. 

Zero Pointer. Height: Approximately 50 meters. Weight: Estimated 3,000 tons. Weapons: None visible, relying purely on kinetic mass. Weaknesses: Joint articulation, specifically the neck servo-motors and the central thermal exhaust.

Logically, engaging it was a waste of energy. He had more than enough points to pass. The most mathematically sound decision was to retreat, preserve his stamina, and wait for the clock to run out. Nezu would have approved of the logical retreat. 

Izuku turned to run. 

"Ow! Help! My leg is stuck!"

Izuku froze. The cry was faint, barely audible over the grinding treads of the approaching titan, but his Full Cowling-enhanced senses caught it. He spun around, his eyes piercing through the settling dust. 

Near the base of the Zero Pointer’s destructive path, a girl was trapped beneath a slab of concrete. It was Uraraka. The girl who had stopped him from falling. 

The Zero Pointer raised a massive, hydraulic fist, preparing to crush the debris—and Uraraka along with it—into powder. 

There was no time for a plan. There was no time to hack. There was no time to deploy tripwires. 

A hero's body must move before their mind can process the danger.

Izuku Midoriya moved. 

He didn't just run. He exploded forward. The green lightning of Full Cowling surged, cracking the pavement beneath his red sneakers. He crossed the street in a fraction of a second, his eyes locked onto the towering machine. 

Five percent won't dent that armor, Izuku’s brain calculated at lightspeed. I need to destroy it. But if I use 100% on my arm without preparation, the hydrostatic shock will shatter my humerus, radius, and ulna, rendering me unable to pull her out of the rubble.

He needed maximum output, but he needed a vector to channel it safely. 

Izuku fired his grapple line. The hook shot upward, wrapping tightly around a steel rebar protruding from the Zero Pointer’s chest plate. The winch screamed as it ripped Izuku off the ground, hauling him directly toward the robot's face. 

As he flew through the air, Izuku pulled his right arm back. He channeled One For All, pushing past the 5% limit. The power surged like a caged sun, screaming through his veins. Red, glowing lines etched across his skin as the sheer kinetic energy stockpiled in his right arm. 

Focus the kinetic discharge! Don't hit the armor! Hit the core!

Izuku brought his left gauntlet up, aiming it at the seam of the Zero Pointer’s neck plating. He fired a micro-EMP pulse directly into the servo-lock. The locking mechanism stuttered, the heavy steel plate popping open slightly, exposing the glowing, superheated exhaust port of the robot's central core. 

Izuku swung perfectly into the opening. 

He didn't throw a traditional punch. He extended his right arm, aligning his bone structure to perfectly distribute the recoil through his shoulders and down into his center of gravity. He locked the electromagnetic dampeners on his support brace to maximum density. 

"DETROIT..." 

Izuku drove his fist directly into the exposed, glowing core of the Zero Pointer. 

"...SMASH!"

The impact was cataclysmic. 

The 100% burst of One For All didn't just dent the machine. It detonated the core from the inside out. A shockwave of golden air pressure erupted from the robot's neck, blowing the entire head clean off its shoulders. The concussive force echoed across the battle center, shattering the remaining glass windows for three blocks. 

The massive body of the Zero Pointer seized, sparks showering from its decapitated stump, before it slowly, agonizingly tilted backward and crashed into the mock city with the force of a meteor. 

Mid-air, Izuku gasped in pain. His right arm was entirely purple, the sleeve of his jacket shredded, but his bones—thanks to the support brace, the perfect posture, and striking a soft internal target rather than solid armor—were miraculously not shattered. They were severely bruised, his muscles torn and screaming, but the limb was intact. 

He plummeted toward the ground. He couldn't use Full Cowling to catch himself with a bum arm. 

"Release!" 

Suddenly, a soft hand slapped his cheek. The overwhelming pull of gravity vanished. Izuku floated gently, inches above the asphalt, right next to Uraraka, who had managed to crawl halfway out from under the rubble. 

She pressed her hands together. "Release!" 

Izuku dropped the remaining three inches, landing on his back with a heavy thud. He panted, staring up at the clear blue sky, his right arm throbbing violently. 

Uraraka, looking pale and exhausted, stared at him in absolute awe. "You... you saved me. You destroyed that thing..." 

"TIME'S UP!" Present Mic’s voice echoed. 

The remaining examinees slowly crept out of their hiding spots, staring at the smoking, headless ruin of the Zero Pointer, and then at the green-haired boy lying on the street. 

"Did he... did he just one-shot the Zero Pointer?"

"But he spent the whole match using gadgets! He had a strength Quirk this whole time?!"

"He saved that girl. He jumped right in..."

Izuku didn't hear them. He closed his eyes, the adrenaline fading, leaving him utterly exhausted. He had done it. He had passed the physical, and he had saved someone. 

A few minutes later, the gentle, scolding voice of Recovery Girl approached. "Oh, dear me. Look at this mess. You boys and your destructive Quirks." 

She planted a kiss on Izuku's forehead. A wave of immense fatigue washed over him as his torn muscles rapidly knit themselves back together. 

"Thank you, Chiyo-san," Izuku mumbled sleepily. 

"Hush now, Midoriya," Recovery Girl chided gently. "Your brother is going to have an absolute fit when he sees this bruising. Now, let's get you up. You have a very bright future ahead of you."

One Week Later

The Midoriya apartment was quiet. 

Izuku sat at his desk in his bedroom, staring intensely at a blank wall. His right arm was still slightly sore, wrapped in an elastic bandage. A small, sealed envelope with the U.A. wax seal rested ominously on his desk mat. 

The door creaked open. Inko peeked her head in, her hands wringing nervously. "Izuku? Your brother is here. He said you got your letter."

"I did," Izuku said, taking a deep breath. 

"Well, open it!" Inko urged. 

Izuku tore the wax seal. A small, metal disc slid out onto the desk. 

The disc whirred to life, projecting a high-definition hologram into the center of the room. But it wasn't a pre-recorded message. It was a live feed. 

The hologram showed All Might, wearing his obnoxious yellow suit, sitting awkwardly behind a desk. 

"I AM HERE AS A PROJECTION!" All Might boomed, coughing slightly. "Young Midoriya! You did brilliantly on the written exam! A perfect score, in fact! And on the practical... well!"

The screen shifted, showing a leaderboard. Izuku Midoriya was at the very top. 

"Seventy-four villain points! An incredible display of tactical ingenuity and technological prowess!" All Might praised. "But that wasn't all! The entrance exam isn't just about fighting! How could a hero course reject someone who risks their life to save another?"

The board updated. 

Izuku Midoriya: 74 Villain Points, 60 Rescue Points. Total: 134 Points. (1st Place).

Izuku felt the breath leave his lungs. He had beaten Kacchan. He had beaten everyone. 

"Young Midoriya," All Might said softly, his booming persona dropping to reveal the genuine, proud mentor beneath. "You have proven that a hero is not measured by the power they are born with, but by the strength of their mind and the courage of their heart. Welcome..."

Suddenly, the hologram flickered. 

A small, white, furry head popped into the frame, completely blocking All Might’s face. 

"Welcome to your Hero Academia, Izuku!" Principal Nezu cheered, holding up a cup of tea to the camera. "I expect you in my office on Monday for your new administrative access codes! We have a school to run, little brother!"

Izuku let out a sound that was half-laugh, half-sob. He buried his face in his hands, the tears of absolute joy finally falling. 

He was going to U.A. High School. 

And heaven help anyone who stood in his way.
