What If Nezu Adopted Deku After the Sludge Incident

 

 

The smell of burning sugar and open sewage would forever be etched into the darkest recesses of Izuku Midoriya’s mind.

 

It was an impossible paradox of scents, sweet and putrid, thick enough to coat the back of his throat and make his eyes water. The alleyway in Tatooin Shopping District was a warzone of shattered concrete, licking flames, and suffocating despair. The heat of the fire rippled the air, distorting the panicked faces of the civilian crowd that had gathered behind the yellow police tape.

 

Izuku stood among them, his yellow backpack heavy against his shoulders, his hands trembling violently.

 

It’s my fault, the thought echoed in his skull, deafening and relentless. All Might dropped the bottle because I grabbed his leg. The villain escaped because of me.

 

Pro Heroes—the very idols Izuku had spent his entire life worshiping, analyzing, and scribbling into worn notebooks—stood helplessly on the periphery. Death Arms grimaced, his muscular arms crossing over his chest as he muttered about not having the right Quirk for a fluid villain. Kamui Woods was busy managing the crowd, his wooden branches keeping the civilians at bay. Mt. Lady was useless in a narrow alley. Backdraft could only focus on the fires.

 

They were waiting. Waiting for someone with the right Quirk. Waiting for someone else to step up.

 

And in the center of that hellscape, struggling against a mountain of dark, viscous sludge, was Katsuki Bakugo.

 

Izuku could see the terror in Katsuki’s crimson eyes. It was a look Izuku had never seen before on the face of his childhood friend-turned-tormentor. Katsuki was drowning. The sludge was forcing its way down his throat, muffling his explosive roars into desperate, wet gurgles. His explosions, usually so precise and devastating, were wild, panicked bursts that only fueled the fires around them.

 

Izuku’s breath hitched. Time seemed to slow to an agonizing crawl.

 

He didn’t have a Quirk. He had been told by a doctor, by his mother, by his teachers, by Katsuki, and just hours ago by All Might himself, that he was powerless. He was a spectator in a world of gods.

 

But as Katsuki’s eyes locked onto his, conveying a silent, desperate plea for help, something in Izuku’s mind violently fractured.

 

The fear evaporated, replaced by a sudden, hyper-focused clarity. The noise of the crowd, the roaring flames, the shouting heroes—it all faded into a dull, white hum.

 

Izuku’s emerald eyes flicked across the battlefield, no longer seeing a chaotic disaster, but a chaotic system of variables.

 

Target: Fluid villain. Weakness: Solid matter. Specifically, the eyes. Only solid points of anatomy visible.

Obstacles: Fire, debris, distance.

Distance: Approximately twelve meters.

Wind trajectory: Updraft from the thermal heat of Bakugo's explosions, shifting the smoke slightly to the left. Wind speed negligible, but thermal draft will alter a lightweight projectile's course by approximately four degrees upward.

 

Izuku’s legs moved before his conscious mind could give the order. He broke past the police line.

 

"Hey! Kid, stop! You'll die!" Death Arms roared, reaching out, but his fingers only grazed the fabric of Izuku’s school uniform.

 

Izuku was sprinting. The heat blistered his skin, but he didn't feel it. His right hand reached over his shoulder, unzipping his backpack in one fluid motion, his fingers wrapping around the thick, reinforced spine of his Hero Analysis for the Future No. 13 notebook. The very notebook Bakugo had exploded and thrown into a koi pond earlier that day. It was waterlogged, heavy, and dense.

 

Perfect projectile weight, his mind calculated coldly.

 

Velocity required: Moderate. Too fast, and the wind resistance catches the frayed pages. Too slow, and the villain dodges.

Angle of release: 42 degrees.

Adjustment for thermal updraft: Lower the angle by 4 degrees. Release at 38 degrees.

Aim for the left eye.

 

Izuku’s arm snapped forward. He didn't just throw the notebook; he launched it with a biomechanical precision born of desperation and an intellect that had spent ten years dissecting the physics of Pro Hero combat.

 

The wet, heavy notebook spun end-over-end, a blur of ruined paper and charred cardboard. It cut through the superheated air, unaffected by the flames, bypassing the wildly flailing tendrils of sludge.

 

Smack.

 

It was a wet, thoroughly satisfying sound. The sharp spine of the notebook struck the sludge villain precisely in the center of its massive, bulging left eye.

 

"AGH! YOU LITTLE BRAT!" The villain shrieked, the sludge violently recoiling as the creature instinctively brought a tendril up to its wounded eye.

 

The grip on Katsuki loosened. The blond boy gasped, tearing his mouth free from the muck, sucking in desperate lungfuls of oxygen. It was only a second of freedom, a microscopic window of opportunity, but it was enough.

 

Izuku was already there, his hands desperately clawing at the sludge. "Kacchan!" he cried out, the cold, calculating fog lifting for a moment, replaced by raw emotion.

 

"What the hell are you doing here?!" Katsuki coughed, coughing up foul-tasting muck.

 

"My legs moved on their own!" Izuku shouted, tears finally spilling from his eyes. "You looked like you needed saving!"

 

The villain recovered, a massive wave of sludge rising up to crush the Quirkless boy who had dared to injure him. Izuku squeezed his eyes shut, bracing for the impact, bracing for death.

 

But the impact never came.

 

Instead, a sudden, localized tornado ripped through the alleyway. The air pressure dropped so violently that Izuku’s ears popped.

 

"I really am pathetic," a deep, booming voice echoed through the clearing smoke.

 

Izuku opened his eyes to see a mountain of muscle standing before him, blood dripping from his mouth, steam rolling off his massive frame. All Might.

 

"I told you the traits that make a great champion... but I see now I wasn't living up to my own ideals!" All Might roared, pulling his fist back. The sheer kinetic energy gathering in his arm seemed to warp the air itself. "PROMINENCE... SMASH!"

 

The punch didn't just hit the villain; it hit the atmosphere. The concussive shockwave tore the sludge villain into a thousand microscopic droplets, instantly scattering them across the alleyway. The force of the wind extinguished the fires in a single, deafening boom, sending a localized rainstorm showering down upon the shopping district as the pressure change forced the clouds above to condense.

 

It was over.

 

 

 

The aftermath was a blur of flashing lights, rain, and shouting.

 

Izuku found himself sitting on the curb, soaked to the bone, staring blankly at the wet pavement. He was being yelled at. Death Arms and Kamui Woods were standing over him, their faces twisted in angry scowls.

 

"What were you thinking, kid?! That was suicidal!" Death Arms berated, waving a massive finger in Izuku’s face. "You don't have a Quirk! You could have gotten yourself and the hostage killed! Leave the hero work to the professionals!"

 

Izuku just nodded slowly, looking down at his hands. He felt hollow. The adrenaline had faded, leaving behind a bone-deep exhaustion and the crushing reality of his existence. He had moved on instinct. He had calculated a perfect strike. But to the world, he was just a reckless, Quirkless liability.

 

A few feet away, Katsuki was surrounded by medics and other Pro Heroes. They were praising him.

 

"What an incredible Quirk you have, kid!" one hero said, clapping Katsuki on the shoulder. "Holding out against a villain like that for so long! When you go pro, come to my agency!"

 

Katsuki didn't look happy. He sat with a towel draped over his shoulders, his eyes locked onto Izuku. There was no gratitude in his gaze, only a chaotic storm of fury, confusion, and wounded pride.

 

Izuku picked up his ruined, waterlogged notebook from the gutter. He bowed to the scolding heroes, apologizing profusely, before turning and walking away from the scene. The crowd parted for him, but no one offered him a word of comfort. Why would they?

 

As he walked the familiar route back to his apartment, the adrenaline completely drained from his system. The sky above was a bruised purple, the setting sun hidden behind the heavy clouds All Might had created.

 

Izuku’s mind was a mess. He replayed the day’s events. The sludge villain under the bridge. All Might’s terrifying true form. The crushing words on the rooftop: I cannot simply say, 'You can become a hero even without power.'

 

"He was right," Izuku whispered to the empty street. "I can't. I'm just... me."

 

He was so lost in his thoughts that he almost didn't hear the sirens.

 

At first, it was just a distant wail, easily dismissible in a city as large as Musutafu. But as Izuku rounded the corner of his neighborhood, the wails grew deafening. Two fire engines blew past him, their tires screeching on the wet asphalt. A police cruiser followed, its lights casting frantic red and blue shadows against the sides of the buildings.

 

Izuku stopped walking. The sirens were converging up ahead. Right where his apartment complex was.

 

A heavy knot formed in his stomach. His feet, which had felt like lead seconds ago, suddenly found a new burst of terrified energy. He began to run.

 

"Mom?" he whispered, his breath puffing into the cool evening air. "Mom, she was going grocery shopping... she should be home by now..."

 

He turned the final corner onto his street, and his world stopped spinning. It didn't just stop; it shattered into a million jagged pieces.

 

The middle section of his six-story apartment building was gone.

 

It looked as though a meteor had struck it horizontally. The third and fourth floors were completely caved in, a massive crater of jagged concrete, exposed rebar, and ruptured water pipes. Smoke billowed into the evening sky, thick and black. Dust covered the street like fresh snow.

 

Police had already set up a barricade. Civilians were gathered, murmuring in panicked hushed tones. Pro Heroes were on the scene, pulling rubble away.

 

Izuku couldn't breathe. His apartment was on the fourth floor. Unit 412. Right where the epicenter of the destruction lay.

 

"No," Izuku choked out. "No, no, no."

 

He pushed through the crowd, his small frame slipping between the onlookers. He reached the yellow police tape and tried to duck under it, but a heavy hand clamped down on his shoulder.

 

"Whoa there, kid! Back up, this is an active disaster zone," a police officer said firmly, pulling him back.

 

"My... my mom," Izuku stammered, his eyes wide and unblinking, fixed on the smoking ruin of his home. "My mom is in there. Unit 412. Please, let me go, I have to find her!"

 

The officer’s stern expression faltered, a flash of deep pity crossing his eyes. "Kid... what's your name?"

 

"Midoriya. Izuku Midoriya. My mom is Inko!" Izuku’s voice pitched upward into a hysterical shriek. He struggled against the officer’s grip, thrashing wildly. "Let me go! She might be trapped! She needs help!"

 

"Midoriya?" Another voice approached. It was a paramedic, her face smudged with soot, a clipboard in her hand. She looked at Izuku, then at the officer, and her expression crumpled. She slowly walked over and knelt down to be at Izuku's eye level.

 

"Izuku... I need you to listen to me, okay?" she said, her voice gentle, too gentle. It was the voice people used when the world had ended and they had to be the ones to break the news.

 

"Where is she?" Izuku demanded, his vision blurring with tears. "Did a hero save her? Is she in an ambulance?"

 

"Izuku..." The paramedic reached out, placing a hand over his. "There was a villain fight three streets over. A villain with a kinetic-enhancement Quirk... he was thrown off course by a hero's attack. He crashed into the building."

 

"I don't care about the villain!" Izuku screamed, his chest heaving. "Where is my mom?!"

 

The paramedic swallowed hard, a tear escaping her own eye. "Izuku... the structural collapse on the fourth floor was instantaneous. The sheer force of the impact... there was no time to evacuate." She squeezed his hand. "I am so, so sorry. She didn't make it. She didn't suffer, Izuku. It was instant."

 

The words hit Izuku harder than any punch Katsuki had ever thrown. They hit harder than All Might’s devastating rejection.

 

She didn't make it.

 

The world tilted on its axis. The roaring of the sirens, the shouting of the heroes, the murmurs of the crowd—it all vanished. A high-pitched ringing filled Izuku’s ears. He stared at the paramedic, but he didn't see her. He saw his mother’s warm smile. He felt her soft hands wiping away his tears when he was four years old and diagnosed Quirkless. He heard her sobbing apologies as she held him.

 

I'm sorry, Izuku! I'm so sorry!

 

His knees gave out. He collapsed onto the wet asphalt, his school uniform soaking in the dirty water. He didn't scream. He couldn't. His throat was locked, suffocating him. He just stared at the smoking crater where his life used to be, his mouth open in a silent, agonizing wail.

 

He was Quirkless. He was alone. And his world had just burned to the ground.

 

 

 

The bureaucratic machinery of the foster care system was a cold, unfeeling beast. It did not care for broken hearts or shattered dreams; it only cared for paperwork, signatures, and housing placements.

 

The funeral had been a blur. A few of Inko’s distant relatives had attended, offering hollow condolences to the shell-shocked boy in the black suit, before quickly making excuses as to why they couldn't take him in. They had their own families. They didn't have the space. And, though no one said it aloud, no one wanted the burden of a Quirkless teenager. In a society built on extraordinary abilities, Izuku was a liability, a genetic dead end.

 

Within a week, Izuku found himself sitting on a hard plastic chair in a drab, gray hallway of the Musutafu Prefectural Orphanage. His belongings were reduced to a single duffel bag containing a few changes of clothes, a framed photograph of him and his mother, and his charred, waterlogged hero notebook.

 

"Midoriya Izuku," a stern-looking social worker called out, flipping through a thick manila folder. She didn't look at him as he stood and walked into her office.

 

The office smelled of stale coffee and old paper. Izuku sat down, keeping his eyes fixed on his lap. He hadn't spoken more than a handful of words in seven days. The endless stream of analytical muttering that used to flow from his lips had dried up, replaced by a deafening, terrifying silence.

 

"Alright, Midoriya," the social worker said, adjusting her glasses. "Your temporary placement is here at the group home. You'll share a room with three other boys. Curfew is at eight PM. Meals are at set times. You will attend the local public middle school starting Monday."

 

She finally looked up, her gaze lingering on a specific line of red ink on his file.

 

"I see here you are registered as Quirkless," she said, her tone devoid of malice, but heavy with professional exhaustion. "I'll be frank with you, Midoriya. The group home environment can be... challenging. Children with strong Quirks often assert dominance. Since you lack one, I advise you to keep your head down, avoid conflict, and stay out of the way. We do not tolerate fighting."

 

Izuku slowly looked up at her. His emerald eyes, once bright and brimming with innocent optimism, were dull, flat, and chillingly empty.

 

"I understand," he said softly. His voice didn't crack. It was perfectly level.

 

He had realized something over the past week. Crying didn't change the past. Hoping for a hero didn't save his mother. The world was a chaotic, brutal system of cause and effect. A Pro Hero had made a mistake, miscalculated an attack, and a villain had been launched into a building. His mother was dead because of a mathematical error in a superhuman brawl.

 

If the world was a system, Izuku realized, then he needed to understand the rules of that system to survive it. He couldn't afford to be the emotional, crying Deku anymore. Deku was weak. Deku relied on others.

 

He took his duffel bag and walked to his assigned room. When he entered, the three other boys—all older, all radiating the arrogant aura of minor physical Quirks—sneered at him.

 

Izuku didn't flinch. He didn't cower. He simply looked at them.

 

Boy on the left: Enlarged forearms, likely a strength enhancement. Heavy footing, poor balance. Center boy: Minor pyrokinesis, scorch marks on his fingertips, breathing is shallow, asthmatic. Boy on the right: Scales on his neck, likely a defensive mutation, but the skin around the eyes is soft and unprotected.

 

He analyzed them in three seconds, mapped out their weak points, categorized their threat levels, and walked past them to claim the empty bottom bunk. The boys, unsettled by the dead-eyed stare of the new kid, said nothing.

 

For Izuku Midoriya, the world was no longer a place of heroes and villains. It was a chessboard. And he was tired of being a pawn.

 

 

 

Across the city, far removed from the bleak reality of the foster system, sat an institution of unparalleled prestige and power. UA High School.

 

Within the labyrinthine corridors of the main building, behind a heavily fortified door, lay the office of the Principal. It was a sprawling, immaculate room, lined with ceiling-high bookshelves filled with texts ranging from advanced quantum physics to classical literature, to the psychology of serial killers.

 

At the center of the room sat a massive mahogany desk. And behind that desk sat a creature that defied conventional classification.

 

He was a chimera of sorts—a blend of a mouse, a dog, and perhaps a bear. He possessed pristine white fur, a scar over his right eye, and a sharply tailored black suit that cost more than most cars. He was Nezu, the Principal of UA, and possessing a Quirk known simply as High Spec, he was arguably the most intelligent being on the planet.

 

Currently, Nezu was engaged in one of his favorite pastimes: drinking high-grade Earl Grey tea and ruthlessly critiquing the incompetence of local Pro Heroes.

 

Multiple holographic screens floated above his desk, replaying various news clips and security camera footage of recent villain attacks. Nezu was conducting his quarterly review of hero efficiency to update the UA curriculum.

 

"Appalling," Nezu muttered, taking a delicate sip from his teacup. He paused the footage of the Sludge Villain incident from a week prior. "Kamui Woods prioritizes crowd control over hostage retrieval, despite his arbor Quirk being perfectly suited for snaring the villain's solid mass. Death Arms relies entirely on brute force and gives up the moment he realizes physical strikes are ineffective. Zero critical thinking. Zero adaptability. And they call themselves professionals. How disappointing."

 

Nezu sighed, his small paws deftly typing on a keyboard to log the failures. He was about to close the file and move on to the next incident when a minor detail in the periphery of the security footage caught his eye.

 

He paused. He rewound the video by fifteen seconds. He zoomed in on the crowd.

 

A boy with unruly green hair. A middle schooler.

 

Nezu watched as the boy suddenly broke from the crowd and sprinted toward the raging fire and the sludge monster.

 

"Foolish," Nezu murmured, though his interest was piqued. Suicidal bravery was common, but rarely did it accomplish anything.

 

Nezu slowed the footage down to a quarter-speed. He watched as the boy reached over his shoulder and pulled a waterlogged notebook from his backpack.

 

And then, Nezu saw it.

 

The boy didn't just throw the book. Before the arm motion even began, Nezu’s hyper-intelligent eyes tracked the boy's micro-expressions. The boy’s eyes darted left, taking in the thermal updraft from the explosions. They darted right, calculating the distance. They locked dead onto the microscopic sliver of the villain's left eye.

 

The boy adjusted his stance, pivoting his hips to generate maximum torque despite his small, unmuscled frame. He altered his wrist angle at the very last millisecond before release.

 

Nezu watched the notebook fly. In his mind, numbers and vectors instantly materialized, painting a complex geometric web over the frozen image.

 

The weight of a soaked, 200-page notebook. The velocity of the throw. The 4-degree upward shift caused by the thermal draft. The exact viscosity of the sludge. The required blunt-force trauma to elicit a pain response and force a muscle spasm.

 

It was a one-in-a-million shot.

 

No. Nezu’s eyes narrowed, a slow, terrifyingly wide smile spreading across his animalistic face.

 

It wasn't luck. It was math.

 

"Computer," Nezu said, his voice laced with sudden, intense fascination. "Run a facial recognition on the green-haired boy. Cross-reference with the national student database."

 

A few seconds later, a file popped up on the screen beside the video.

 

Name: Midoriya Izuku.

Age: 14.

Quirk: None (Registered Quirkless).

Status: Orphaned. Ward of the State.

 

Nezu’s smile faded slightly as he read the boy’s recent history. The mother, Midoriya Inko, killed as collateral damage in a Pro Hero conflict just hours after the Sludge Incident. The boy was currently residing in a low-income group home in the industrial district.

 

Nezu tapped his claws against the mahogany desk, a rhythmic click, click, click echoing in the silent office.

 

Quirkless, Nezu thought. Shunned by society. Deemed worthless by a system that values genetic lottery over genuine capability. A mind capable of calculating advanced ballistic trajectories and fluid dynamics under extreme duress, trapped in the body of a vulnerable, grieving child.

 

Nezu looked at his own paws. He remembered a time, long ago, when he had been deemed worthless. When humans in white lab coats had looked at him not as a brilliant mind, but as a rat to be experimented on. They had tortured him. They had underestimated him.

 

He had made them pay for that underestimation. He had risen above them all to command the most powerful institution in the country.

 

Nezu looked back at the screen, at the frozen image of Izuku Midoriya throwing that notebook. He didn't see a helpless, Quirkless boy. He saw a diamond in the rough. He saw a mind that, if properly nurtured, honed, and weaponized, could outthink every single Pro Hero on the top ten billboard chart.

 

He saw a kindred spirit.

 

"Well, well, Midoriya Izuku," Nezu murmured, his beady black eyes gleaming with a mixture of profound empathy and dangerous calculation. "It seems the universe has dealt you a terribly cruel hand. But I have always been quite fond of overturning the board."

 

Nezu hopped down from his oversized leather chair. He walked over to his custom-built coat rack and donned a small, elegant trench coat.

 

"Computer, cancel my afternoon meetings with the hero commission," Nezu commanded as he headed for the door. "And prepare my car. I have a visit to make."

 

 

 

The rain outside the Musutafu Prefectural Orphanage was relentless, a gray, oppressive sheet of water that matched the dreary interior of the building.

 

Izuku sat by the window in the recreation room, ignoring the blaring television and the roughhousing of the other orphans. He had a stolen stub of a pencil in his hand and a scrap of paper he had salvaged from the trash.

 

He wasn't drawing heroes. He was drawing architectural schematics. He had spent the last two hours analyzing the structural integrity of the group home from memory, calculating exactly where the load-bearing walls were, and hypothesizing how easily the roof would collapse in the event of a minor earthquake.

 

It was a morbid exercise, a trauma response to the collapse of his apartment, but it kept his mind occupied. It kept the memories of his mother at bay.

 

Suddenly, a sleek, jet-black limousine pulled up to the curb outside the window. It was a vehicle that belonged in the elite districts of Tokyo, not the slums of Musutafu. The tinted windows rolled up, obscuring the interior, but the sheer presence of the car silenced the entire recreation room.

 

A moment later, the front door of the orphanage burst open. The head social worker scurried out of her office, looking more frantic and terrified than Izuku had ever seen her.

 

Following closely behind her, flanked by two towering men in black suits, was a creature Izuku instantly recognized.

 

Principal Nezu of UA.

 

Izuku’s pencil paused mid-stroke. His analytical mind immediately kicked into overdrive.

 

Principal Nezu. Quirk: High Spec. The only known animal to manifest a Quirk. Intelligence surpasses human genius levels. Why is the head of the most prestigious hero academy in the country in a rundown foster home?

 

Nezu’s dark eyes swept the room. The other children shrank back, intimidated by the bizarre, suited animal and his menacing bodyguards. Nezu ignored them entirely. His gaze locked onto the boy sitting by the window.

 

Nezu raised a paw, dismissing the social worker, who bowed frantically and practically ran back to her office. He signaled his bodyguards to remain at the door.

 

With measured, deliberate steps, Nezu crossed the linoleum floor and stopped in front of Izuku.

 

Up close, Nezu was unnerving. He was undeniably cute, resembling a plush toy, but his eyes were ancient, cold, and possessed an intellect so sharp it felt as though he were dissecting Izuku’s soul just by looking at him.

 

"Midoriya Izuku, I presume?" Nezu spoke, his voice polite, refined, and perfectly modulated.

 

Izuku didn't stand up. He didn't bow. He simply held Nezu’s gaze, his own eyes devoid of the hero-worship they once held, replaced by a guarded, calculating stare.

 

"Principal Nezu," Izuku replied, his voice quiet but steady. "To what do I owe the honor?"

 

Nezu’s smile widened just a fraction. He noted the lack of panic, the lack of awe. He liked this boy already.

 

Without asking for permission, Nezu hopped up onto the chair opposite Izuku. He reached into his trench coat and pulled out a small, stainless-steel thermos and two porcelain teacups, setting them on the small table between them.

 

"I find that all important conversations are best had over a good cup of tea," Nezu said casually, unscrewing the thermos. A rich, bergamot-scented steam wafted into the air as he poured the amber liquid. He pushed a cup toward Izuku. "Earl Grey. Drink."

 

Izuku looked at the tea, then at Nezu. He didn't touch the cup.

 

"Why are you here?" Izuku asked again, ignoring the tea. "If this is a charity visit from UA, you're wasting your time. I'm Quirkless. I have nothing to offer an academy of heroes."

 

"Ah, straight to the point. Excellent," Nezu chuckled, taking a slow sip from his own cup. "I am not here for charity, Midoriya. I abhor charity. It implies pity, and pity is an insult to capability. I am here because of a video I watched this morning."

 

Nezu reached into his coat again and produced a small, flat tablet. He placed it on the table and tapped the screen. The footage of the Sludge Villain incident played.

 

Izuku’s breath hitched slightly, his eyes narrowing at the screen. The memory of the flames, the smell of the sludge, the terror in Katsuki’s eyes—it all rushed back, threatening to break his carefully constructed emotional dam. But he forced it down, burying it under logic.

 

Nezu paused the video exactly at the moment Izuku threw the notebook.

 

"A 38-degree release angle, compensating for a four-degree thermal updraft," Nezu said softly, his dark eyes never leaving Izuku’s face. "Targeting a surface area of less than ten square inches from twelve meters away, with a projectile whose aerodynamic properties are virtually nonexistent. A calculation made in under eight-tenths of a second, while under extreme psychological duress."

 

Izuku stared at the tablet. "I... I just threw it. I was trying to save my friend."

 

"Do not lie to me, Midoriya. And more importantly, do not insult your own intelligence," Nezu said, his tone suddenly hardening, losing its polite veneer and revealing the razor-sharp apex predator beneath. "The heroes at the scene called you reckless. They called you foolish. Because they are brute-force Neanderthals who rely entirely on their genetic lottery to solve problems."

 

Nezu leaned forward, resting his paws on the table.

 

"I do not see a reckless child," Nezu whispered, his voice intense. "I see a tactical genius. I see a mind that operates on a frequency few humans will ever comprehend. I see someone who looked at an impossible equation and solved it in an instant."

 

Izuku’s hands began to tremble. Not from fear, but from something entirely alien. Validation. For fourteen years, he had been called a useless Deku. He had been told his mind didn't matter because his body lacked a Quirk. And here, the smartest being on the planet was looking at him with undeniable respect.

 

"My mother is dead," Izuku said suddenly, his voice cracking, the raw grief finally bleeding through his stoic mask. He hadn't meant to say it, but the words tore themselves from his throat. "I solved the equation... I saved him... and the heroes... the heroes messed up... and she's dead. What good is my brain if I couldn't save her?"

 

Nezu’s expression softened, the dangerous edge fading into a profound, heavy sorrow. He reached out, his small, white paw gently resting over Izuku’s trembling hand.

 

"The world is a deeply flawed, agonizingly unfair system, Izuku," Nezu said, using the boy's given name for the first time. "It favors the strong, ignores the weak, and covers up its mistakes with flashy smiles and bright colors. The heroes who caused the collateral damage that killed your mother will likely face nothing more than a reprimand."

 

Izuku clenched his jaw, tears finally spilling over his eyelashes and tracking down his cheeks. He didn't wipe them away.

 

"You have two choices before you," Nezu continued, his voice a steady, grounding anchor in the storm of Izuku’s grief. "You can remain here. You can let the system crush you. You can let the world tell you that you are nothing but a Quirkless tragedy, a footnote in a police report."

 

Nezu withdrew his paw and picked up his teacup, taking another sip before offering a smile—not a warm, comforting smile, but a sharp, calculating, terrifyingly polite smile.

 

"Or," Nezu said softly, "you can come with me. I cannot bring your mother back, Izuku. But I can give you the tools, the resources, and the authority to dismantle the very system that allowed her to die. I can teach you how to make the world play by your rules."

 

Izuku stopped crying. He looked at the strange, chimera principal.

 

"I am offering to legally adopt you as my ward," Nezu stated clearly. "You will live at UA High School. You will be my personal student. I will train your mind until it is the most dangerous weapon on the planet. And when the time comes, you will prove to this society that a Quirk is nothing compared to absolute, unyielding intellect."

 

Nezu nudged the cup of Earl Grey closer to Izuku.

 

"So, Izuku Midoriya. How would you like to live at UA?"

 

The recreation room around them was completely silent. The rain beat heavily against the window glass.

 

Izuku looked down at the scrap of paper where he had drawn the structural weak points of the building. He looked at his scarred, Quirkless hands. Then, he looked at Nezu.

 

The boy who had cried over a ruined notebook, the boy who had worshipped All Might, the boy who had dreamed of a power he could never have—that boy had died in the rubble of apartment 412.

 

The boy who remained reached out. His hand was no longer trembling. He picked up the porcelain cup.

 

He brought it to his lips, took a slow, deliberate sip of the bitter tea, and set it back down on the saucer with a soft, decisive clink.

 

Izuku looked Principal Nezu in the eye, and for the first time in a week, the corners of his mouth twitched upward. It was a mirror image of Nezu’s own expression. A closed-eye, overly polite, deeply terrifying smile.

 

"I think I would like that very much, Principal Nezu," Izuku said quietly.

 

Nezu’s eyes gleamed with triumphant delight. "Excellent. Pack your things, Izuku. We have a great deal of work to do."

 

As the chimera and the boy stood up and walked toward the exit, leaving the stunned orphans and the drab reality of the foster system behind them, the trajectory of the future irrevocably shifted.

 

Society would soon learn a very harsh lesson. A Quirk was merely biology. But a brilliant mind, forged in trauma and mentored by a monster, was absolute power.

 

 

 

 

The gates of UA High School loomed like the entrance to a fortress, an imposing structure of steel, glass, and cutting-edge security that separated the elite from the ordinary. To the rest of the world, it was a beacon of hope, the very crucible where the Symbol of Peace had been forged.

 

To Izuku Midoriya, staring at it through the tinted windows of a sleek black limousine, it was something entirely different. It was a sanctuary. It was a laboratory. And, most importantly, it was his new home.

 

The rain that had started at the orphanage was still falling, washing the streets of Musutafu in a cold, gray blur. But as the limousine glided smoothly through the massive gates—which parted automatically at the vehicle’s encrypted proximity signal—the chaotic noise of the city seemed to instantly vanish, replaced by the hushed, almost reverent silence of the sprawling campus.

 

Izuku sat perfectly still in the plush leather seat, his yellow backpack resting on his knees. He didn't press his face against the glass in awe as he would have done just a week ago. He simply observed. He noted the exact placement of the security cameras hidden within the decorative masonry. He counted the patrol drones buzzing silently along the perimeter wall. He calculated the response time required for the automated defense shutters on the main building to deploy in the event of an aerial assault.

 

"Impressive, isn't it?" Principal Nezu’s polite, cultured voice broke the silence in the cabin. The chimera was sitting across from Izuku, casually stirring a small cup of tea that he had poured from his ubiquitous thermos. "The security system was entirely my design. It operates on a closed-loop network, immune to external cyber-attacks, and utilizes an algorithmic prediction model to identify threats before they breach the outer wall."

 

Izuku blinked, his emerald eyes shifting from the window to the principal. "It relies on thermal imaging and biometric scanning," Izuku stated softly. It wasn't a question. "But the patrol drones are operating on a fixed, staggered patrol route to conserve battery life in the rain. There's a blind spot."

 

Nezu paused, his spoon clinking gently against the porcelain. His beady black eyes locked onto the boy. "Oh? Do enlighten me, Izuku."

 

"Sector four, near the northern training grounds," Izuku said, his voice flat, devoid of the nervous stammer that had plagued him for fourteen years. "The trees are denser there. The drones elevate to avoid the canopy, but the thermal imaging struggles to penetrate the wet foliage. If a person with an average body temperature moved at a pace of less than two meters per second during a heavy downpour, they could slip beneath the drone's sensory cone for approximately forty-two seconds. Enough time to scale the wall if they possessed a mobility Quirk."

 

Silence hung in the cabin. The only sound was the rhythmic thrum of the rain against the roof of the car.

 

Slowly, Nezu’s lips curled upward into that terrifying, closed-eye smile. "Forty-two seconds," the principal murmured, his voice practically purring with delight. "I had calculated forty-five. It seems I failed to account for the specific interference caused by the density of the autumn foliage in this particular rainfall. Good catch, my boy. I shall have Power Loader update the drone firmware immediately."

 

The limousine rolled to a gentle stop outside a large, modern, multi-story building situated a short distance from the main academic blocks. This was the faculty dormitory, a highly secure facility designed to house the Pro Heroes who taught at the school.

 

"Come along," Nezu said, hopping down from his seat. "Let us get you settled in."

 

The interior of the teacher's dorms was a stark contrast to the dreary, depressing atmosphere of the orphanage. It was warm, brightly lit, and smelled faintly of expensive coffee and polished wood. Nezu led Izuku past a common area—where a massive, yellow sleeping bag currently lay abandoned on a sofa—and toward a private elevator at the end of the hall.

 

Nezu pressed his paw against a biometric scanner, and the elevator doors slid open. "My private suite is located on the top floor. It spans the entire level, providing ample room for my... eccentricities. And now, yours."

 

When the elevator doors opened on the top floor, Izuku stepped out into a space that defied all architectural logic.

 

The suite was a labyrinth of towering bookshelves, some reaching the ten-foot ceilings, packed with tomes in dozens of different languages. There were whiteboards covered in complex mathematical equations, geopolitical maps with various red strings connecting villain organizations, and an entire corner dedicated to a massive, multi-tiered tea station that looked more like a chemistry lab than a kitchen.

 

What was most jarring, however, was the juxtaposition of scale. There was human-sized furniture—plush leather armchairs, a large mahogany dining table—and right beside it, smaller, custom-built furniture perfectly proportioned for Nezu. It was a physical manifestation of a mind that bridged the gap between two worlds.

 

"Your room is down the hall to the left," Nezu said, gesturing with a paw as he walked toward a large desk. "I had the staff furnish it with the essentials before I arrived at the orphanage. We can acquire personal decorations at a later date."

 

Izuku walked down the hallway, his footsteps silent on the thick Persian runner. He opened the door to his left and stepped inside.

 

It was a large room, larger than his entire old apartment. It featured a queen-sized bed with crisp, gray linens, a massive oak desk situated in front of a window overlooking the campus, and a state-of-the-art computer setup.

 

But it was entirely empty of personality. There were no All Might posters. There were no action figures. There were no limited-edition bedsheets. It was a blank canvas.

 

Izuku dropped his yellow backpack onto the floor. He walked over to the edge of the bed and sat down. He stared at the blank white wall opposite him.

 

For the first time since the social worker had handed him his mother's death certificate, Izuku felt the crushing weight of reality threatening to break through his analytical defenses. The sheer quiet of the room was deafening. There was no sound of his mother humming in the kitchen. There was no smell of katsudon frying on the stove.

 

His chest tightened. His breath came in short, jagged gasps. He reached into his pocket and pulled out the crumpled, slightly charred photograph of him and Inko at the amusement park when he was four years old.

 

Izuku squeezed his eyes shut. A single, treacherous tear escaped, tracing a hot path down his cheek. He allowed himself exactly sixty seconds. Sixty seconds to grieve the boy who had died in the rubble, and the mother who had loved him unconditionally.

 

When the sixty seconds were up, Izuku opened his eyes. The warmth was gone from them, replaced by the cold, hard emerald of a sharpened blade. He carefully placed the photograph on the bedside table.

 

He was not Deku anymore. Deku was a victim.

 

Izuku stood up, smoothed out his uniform, and walked back out into the main living area.

 

Nezu was sitting at the low coffee table, two cups of tea already poured. Between the cups sat a pristine, handcrafted wooden chessboard, the pieces already set in their starting positions. Beside the board lay a thick stack of legal documents.

 

"Sit, Izuku," Nezu instructed.

 

Izuku sat on the floor opposite the principal, folding his legs beneath him.

 

Nezu pushed the stack of papers forward. "These are the final adoption papers, expedited by the highest courts in the Musutafu Prefecture. I utilized several legal loopholes regarding emergency ward placements for Quirkless minors in high-risk environments. By signing the bottom line, you will officially become my son in the eyes of the law."

 

Izuku looked at the documents. The legal jargon was dense, but his eyes quickly scanned the clauses.

 

"Why go through the legal trouble?" Izuku asked, his voice steady. "You could have just kept me here as a 'special student' without binding yourself to me."

 

"Because, Izuku, the world is a game of legal and political chess," Nezu replied, picking up a white pawn. "As a Quirkless orphan, you have zero rights. The Hero Public Safety Commission could scoop you up, throw you into a manual labor facility, and the public would not blink. But as the legally adopted son of Principal Nezu, you inherit my protections. My diplomatic immunity, my financial assets, and my authority on this campus. No Pro Hero, no police officer, and no politician can touch you without declaring war on me."

 

Nezu moved his white pawn forward two spaces. King’s Pawn opening. "Now. Sign the papers, and take your turn."

 

Izuku picked up the expensive fountain pen resting beside the documents. He didn't hesitate. He signed Izuku Midoriya in neat, precise strokes. Then, he looked at the board, picked up a black pawn, and mirrored Nezu's move.

 

"Are we playing a standard game?" Izuku asked.

 

"There is nothing standard about the life you are entering, my boy," Nezu said, moving a knight. "This game is your first lesson. Your mind is sharp, yes. But it is currently disorganized, operating entirely on instinct and grief. I am going to teach you how to weaponize it. I am going to teach you how to see not just the next move, but the next fifty."

 

For the next two hours, they played. And Izuku lost. Brutally.

 

Every time Izuku tried to build a conventional defense, Nezu dismantled it with a bizarre, seemingly nonsensical move that wouldn't pay off until six turns later, completely trapping Izuku’s pieces. Nezu didn't play to take pieces; he played to control the space, forcing Izuku into a corner where his only option was surrender.

 

"Checkmate," Nezu said softly, sipping his tea.

 

Izuku stared at the board, his brow furrowed in intense concentration. He replayed the entire game in his head, tracing back the exact moment he had lost control of the center of the board.

 

"You rely too much on protecting your high-value assets," Nezu observed, his tone analytical. "You kept trying to save your Queen, pulling your knights and bishops out of position to defend her. You view the Queen as your Symbol of Peace. You think that if she falls, the game is over."

 

Izuku looked up.

 

Nezu leaned forward, his black eyes boring into Izuku’s soul. "In the real world, Izuku, the Queen is just another piece of wood. The objective is to kill the enemy King. If you have to sacrifice your Queen, your rooks, and every single pawn on the board to corner the King, you do it. Sentimentality will get you killed. You must learn to be ruthlessly pragmatic."

 

Nezu reset the board with blinding speed. "Again."

 

They played five more times. Izuku lost the first four. But on the fifth game, something shifted.

 

Nezu moved to trap Izuku’s Queen, executing the exact same pincer maneuver he had used in game three. Izuku saw it coming. The old Izuku would have panicked and retreated the Queen.

 

Instead, Izuku picked up his Queen and moved her directly into the line of fire of Nezu’s bishop, intentionally leaving her completely exposed. In the same turn, this move cleared a diagonal path for his own bishop to align perfectly with his knight, pinning Nezu’s King behind his own pawns.

 

Nezu paused. His paw hovered over the board. He looked at Izuku’s exposed Queen, then at his own trapped King.

 

Izuku picked up his teacup, mirroring Nezu’s posture perfectly. He took a slow sip of the Earl Grey, offering the chimera a terrifyingly polite, closed-eye smile.

 

"Mate in three," Izuku said softly.

 

Nezu stared at the boy. Then, the principal threw his head back and let out a loud, genuine bark of laughter.

 

"Splendid!" Nezu cheered, clapping his paws together. "Absolutely splendid! You sacrificed the Symbol to win the war. You learn terrifyingly fast, my boy. Yes, indeed. We are going to have so much fun together."

 

 

 

The next morning, the UA staff room was its usual organized chaos.

 

The room smelled of stale coffee, expensive cologne, and exhaustion. Snipe was adjusting his holsters in the corner, Cementoss was quietly grading papers, and Hizashi Yamada—the Pro Hero Present Mic—was vibrating with too much energy for an 8:00 AM Tuesday.

 

"I'M TELLING YOU, SHOTA, THE NEW DJ DECK IS REVOLUTIONARY!" Hizashi boomed, leaning over a desk where a man looking like a homeless caterpillar was attempting to sleep inside a yellow sleeping bag.

 

Shota Aizawa, the Pro Hero Eraserhead, cracked open one bloodshot eye. "If you don't lower your voice, I am going to strangle you with your own speaker wire."

 

Before Hizashi could respond, the heavy reinforced doors of the staff room slid open.

 

The room instantly quieted down out of habit as Principal Nezu strolled in. But the silence quickly turned to palpable confusion as a teenager in a pristine, perfectly tailored UA uniform—sans the traditional red tie, which had been replaced by a sleek black one—walked in silently, exactly one step behind the principal.

 

The boy carried a silver tray holding a steaming teapot and two porcelain cups. His expression was completely blank, his emerald eyes scanning the room, lingering on each hero for a fraction of a second.

 

"Good morning, esteemed faculty!" Nezu chirped cheerfully, hopping up into his elevated chair at the head of the central conference table. "I trust you all had a restful evening?"

 

Nemuri Kayama, the R-Rated Hero Midnight, leaned over her desk, her eyes wide as she stared at the boy. "Nezu, honey... did you kidnap a middle schooler?"

 

"Certainly not!" Nezu laughed. "Everyone, I would like you to meet Midoriya Izuku. He is my legally adopted son, my new personal ward, and as of today, he holds Level-4 security clearance on this campus. He outranks all of you in administrative matters save for myself and Recovery Girl."

 

Aizawa sat up in his sleeping bag, the zipper screeching loudly in the quiet room. His dark eyes locked onto Izuku. The underground hero instantly recognized the look in the kid's eyes. It was the thousand-yard stare of a veteran who had seen too much, poorly masked by a terrifyingly calm veneer.

 

"A kid?" Aizawa rasped, his voice dripping with suspicion. "You adopted a human kid? Nezu, this isn't a pet project. Why is he here?"

 

"I'm right here, Eraserhead," Izuku said.

 

The entire room flinched. The kid's voice wasn't loud, but it cut through the room with the precision of a scalpel. It sounded exactly like Nezu’s tone of voice—polite, cultured, and laced with an underlying threat.

 

Izuku smoothly placed the silver tray on the table. He poured a cup of tea, handed it to Nezu, poured a second for himself, and turned to face the scraggly hero.

 

"Shota Aizawa," Izuku began, taking a calm sip of his tea. "Quirk: Erasure. Capable of nullifying emitter and transformation-type Quirks by maintaining visual contact. Drawback: Dry eye, and the effect drops when you blink. You rely entirely on your carbon-fiber capture weapon to subdue villains who outmatch you in physical strength while their Quirks are disabled."

 

Aizawa’s eyes narrowed dangerously, his capture weapon beginning to subtly float around his neck.

 

"However," Izuku continued, unbothered by the threat, his eyes tracking the floating cloth, "your reliance on intimidation and stealth has left you with a distinct vulnerability to psychological profiling. You project an aura of apathy to keep people at a distance, but the callouses on your index and middle fingers suggest you spent an extra three hours on patrol last night, likely tracking the minor smuggling ring operating out of the Hosu docks. You are chronically sleep-deprived, meaning your blink rate has increased by approximately fifteen percent, giving an opponent a 1.2-second window to exploit your Quirk's downtime."

 

The staff room was dead silent. Present Mic’s jaw was literally hanging open. Midnight was staring at Izuku with a mixture of shock and profound awe.

 

Aizawa’s Quirk flared to life, his eyes glowing a menacing red, his hair standing on end as he tried to erase whatever analytical Quirk this terrifying child possessed.

 

Izuku didn't flinch. He just smiled, a closed-eye, perfectly polite Nezu smile.

 

"I am Quirkless, Eraserhead," Izuku said softly, savoring the shock that registered on Aizawa’s face. "Your Quirk is useless against me. Just as your intimidation tactics are."

 

Aizawa blinked. His hair fell flat. The glowing red faded from his eyes. He stared at the kid, then slowly turned his head to look at Nezu, who was currently beaming with the pride of a father watching his son take his first steps.

 

"God help us," Aizawa muttered, rubbing his temples. "You cloned yourself."

 

"Oh, he's so cute!" Midnight suddenly squealed, breaking the tension. She practically teleported across the room, wrapping her arms around Izuku and pulling his face into her chest. "He's like a little, dark, brooding genius! Can I keep him, Nezu? Can I?"

 

"He is not a toy, Nemuri," Nezu chuckled.

 

Izuku skillfully ducked out of Midnight's suffocating embrace, adjusting his collar. He calculated the exact trajectory to step out of her reach without seeming rude. "It is a pleasure to meet you all," Izuku said, bowing slightly. "I look forward to optimizing your hero protocols."

 

"Optimizing...?" Present Mic echoed, looking slightly terrified.

 

"Indeed," Nezu said, clapping his paws. "Izuku is currently undergoing a specialized curriculum under my direct tutelage. Speaking of which, Izuku, how goes the project I assigned you last night?"

 

Izuku pulled a sleek tablet from his blazer pocket. "I successfully bypassed the Level-2 firewall on the UA mainframe at 3:14 AM. The security architecture relies on an outdated AES-256 encryption for the student files. I found a vulnerability in port 443. I rewrote the access protocols and patched the backdoor so external hackers cannot replicate my entry."

 

Power Loader, who had been quietly working on a blueprint in the corner, suddenly choked on his coffee. "You bypassed the mainframe?! That takes a team of professional hackers weeks!"

 

"I utilized a Trojan script masked as an automated thermal-update ping from the external security drones," Izuku explained casually, sipping his tea. "The system recognized the drone's signature and let the script inside the firewall. It was quite elementary."

 

"And the second task?" Nezu asked, thoroughly enjoying the sheer terror radiating from his staff.

 

"I memorized the Hero Public Safety Commission's penal code volumes one through seven," Izuku replied, pulling up a document on his tablet. "I noted forty-seven distinct legal loopholes regarding the use of unregistered Quirks in self-defense scenarios. Specifically, Section 4, Paragraph 12, which states that any action resulting in property damage is entirely absolved if the civilian is acting under the 'Good Samaritan' doctrine to prevent lethal harm, provided the Pro Hero on scene fails to establish a secure perimeter."

 

Izuku looked up, his eyes locking onto Mount Lady, who was featured on a news broadcast playing on the staff room TV, currently destroying a bridge to catch a purse snatcher. "Most heroes are bleeding money in liability claims because they don't know the law. If Mount Lady had simply declared the bridge a 'lethal hazard zone' three seconds before destroying it, the city would be legally obligated to cover the repair costs, saving her agency approximately four million yen."

 

The staff room was silent once more.

 

"He's fourteen," Nezu told the room proudly. "And he's only been my student for twelve hours."

 

Aizawa slowly zipped his sleeping bag all the way up over his head. "Wake me up when the world ends. Because it's clearly starting today."

 

 

 

The next month was a blur of relentless, agonizing, glorious mental expansion for Izuku.

 

There was no physical training. There were no push-ups, no running, no weightlifting. Nezu argued that physical strength was entirely useless if the mind driving it was not sharper than a diamond.

 

Instead, Izuku’s training consisted of psychological warfare.

 

At 6:00 AM, they drank tea and played chess, usually with three boards simultaneously.

 

At 9:00 AM, Nezu would hand Izuku cold-case files of unsolved villain murders. Izuku had to deduce the killer’s Quirk, motive, and current location using only crime scene photos and autopsy reports. By the third week, Izuku had solved six cases, leading the police to arrest three fugitives who had been hiding for over a decade. The police department was terrified of the anonymous tips coming from UA.

 

At 1:00 PM, Izuku studied coding, mechanical engineering, and applied physics. He spent hours in the Support Studios, watching Power Loader work, analyzing how support gear could compensate for a lack of a Quirk.

 

At 5:00 PM, the real training began. Nezu called it "Hero Dissection."

 

They would sit in the principal’s office, watching footage of the top ten Pro Heroes.

 

"Endeavor," Nezu would say, freezing a video of the Number Two hero blasting a villain. "Analyze."

 

"Over-reliant on overwhelming firepower," Izuku would respond instantly, not looking up from the notebook where he was currently redesigning the aerodynamic fins of Snipe’s bullets. "He fails to regulate his core body temperature effectively during prolonged engagements. If an opponent with a high-mobility Quirk were to force him into a war of attrition, evading his blasts for exactly fourteen minutes, Endeavor’s cognitive functions would slow due to hyperthermia. A simple kinetic strike to his lower back—where his armor is thinnest to allow for heat venting—would paralyze him."

 

"Excellent. Hawks?"

 

"Arrogant. He relies on sensory feedback from his feathers. If you isolate him in a soundproof environment and use a high-frequency sonic emitter, the vibrations would disorient the spatial awareness of his feathers, grounding him completely."

 

Izuku was changing. The trauma of losing his mother was still there, a cold, heavy stone in his chest, but Nezu was teaching him how to use that pain as fuel for his intellect. Izuku’s posture straightened. He stopped looking at the floor. He began to carry himself with the quiet, terrifying confidence of someone who knew exactly how to dismantle every person in the room.

 

He was becoming a reflection of his mentor. He moved silently, often dropping down from the ventilation shafts to hand Aizawa a cup of coffee just to watch the underground hero flinch. He smiled politely when insulted. He spoke softly, knowing that a quiet voice forced people to lean in and listen, giving him psychological dominance over a conversation.

 

And then, one Tuesday afternoon, the final piece of the chessboard walked into the principal's office.

 

Izuku was standing by the large window, a teacup resting on a saucer in his left hand. He was wearing his black UA uniform, the jacket unbuttoned, analyzing the structural integrity of the newly constructed USJ facility on his tablet. Nezu was sitting at his desk, humming a cheerful tune.

 

A heavy, rhythmic knock sounded at the door.

 

"Enter," Nezu called out.

 

The door opened, and a skeletal man with sunken eyes, shaggy blonde hair, and clothes that hung off his emaciated frame stepped inside. He coughed, a small spatter of blood landing in his palm, which he quickly wiped away with a handkerchief.

 

"Ah, Yagi! Welcome, welcome!" Nezu greeted warmly. "Please, take a seat. I've been expecting you to finalize your teaching contract for the upcoming year."

 

Toshinori Yagi—the true form of All Might, the Symbol of Peace—smiled weakly, stepping into the room. "Thank you, Principal Nezu. I appreciate the opportunity. My... time limit... has been decreasing rapidly since the incident last month. Teaching seems to be the logical next step."

 

"Indeed," Nezu agreed. "Allow me to introduce you to my personal ward and assistant. He handles all my confidential paperwork."

 

Toshinori turned toward the window.

 

Izuku slowly turned around. He took a sip of his tea, the saucer perfectly balanced. His face was entirely devoid of the absolute panic and hero-worship that had consumed him the last time they had met on that rooftop.

 

Toshinori’s hollow blue eyes widened in shock. The memory of the sludge villain incident flashed in his mind. The Quirkless boy. The one he had told to be a police officer. The one who had thrown a notebook and saved young Bakugo when Toshinori himself had been too weak to move.

 

"You..." Toshinori gasped, pointing a bony finger. "You're the boy from the alleyway! The... the Quirkless boy!"

 

Izuku offered a slow, chillingly polite smile, his eyes curving into half-moons exactly like Nezu’s.

 

"It is a pleasure to meet you properly, All Might," Izuku said, his voice smooth and steady. He walked over to the desk, poured a cup of tea, and handed it to the stunned hero. "Drink. Chamomile. It will help soothe your inflamed respiratory tract, given the severe trauma to your left lung and missing stomach."

 

Toshinori nearly dropped the cup. He whipped his head around to stare at Nezu. "How... how does he know about my injury?! That is an S-class state secret!"

 

Nezu laughed, a bright, cheerful sound that echoed menacingly in the large office. "My dear Yagi, Izuku deduced the nature of your injury three weeks ago by cross-referencing the shifting micro-expressions of pain on your face during public appearances with the timeline of your battle against Toxic Chainsaw—which, of course, was a cover story for your battle with Him."

 

Toshinori slumped into the chair, clutching the teacup like a lifeline. He looked at Izuku, seeing not a helpless fanboy, but a calculating, unnervingly calm young man who exuded an aura of absolute control.

 

"I don't understand," Toshinori whispered. "Why is he here?"

 

"Because, Yagi, you are dying," Nezu said bluntly, the cheerfulness vanishing from his voice, replaced by cold, hard reality. "Your flame is going out. You came to UA to find a successor for your Quirk. You came to find a vessel for One For All."

 

Toshinori flinched as if struck. "You... you know about One For All?"

 

"I know everything, Yagi. And I know that your search for a successor has been flawed from the start," Nezu stated, intertwining his paws on the desk. "You are looking for a clone of yourself. You are looking for a symbol of brute strength and blind, smiling optimism. But that era is over. The villains are evolving. They are becoming smarter, more organized. If you give One For All to a brute, they will be outmaneuvered and killed."

 

Nezu stood up on his chair, pointing a paw directly at Toshinori.

 

"One For All requires a new kind of wielder. It does not need a smiling idiot who punches first and thinks later. It needs a tactician. It needs a commander. It needs someone who can dismantle the enemy’s mind before ever throwing a punch."

 

Toshinori looked back at Izuku. The boy was calmly sipping his tea, his eyes fixed on the Symbol of Peace, utterly unbothered by the gravity of the conversation.

 

"You... you want me to give One For All to him?" Toshinori asked, his voice trembling. "But... he's Quirkless. And... respectfully, Nezu, he terrifies me."

 

"He should," Nezu smiled, his teeth glinting in the light. "Because if you give him that power, Yagi, he will not be your carbon copy. He will not be a Symbol of Peace."

 

Izuku set his teacup down. He walked forward, standing right in front of the Number One Hero. The boy who had once cried on a rooftop, begging for a chance, now looked down at his idol with the calculating gaze of an apex predator.

 

"I will be a Symbol of Victory, All Might," Izuku said softly, his voice echoing with absolute, terrifying certainty. "Because I don't just want to save people. I want to ensure the villains who hurt them never walk again. I want to break the board."

 

Toshinori stared into the emerald eyes of the boy before him, realizing with a sudden, bone-deep certainty that Principal Nezu had not just adopted a child.

 

He had forged a weapon.

 

And now, Nezu was asking All Might to give that weapon the power of a god.

 

 

 

 

The silence in the principal’s office was absolute, thick enough to be sliced with a katana.

 

Toshinori Yagi, the Symbol of Peace, sat rigidly in his chair, his skeletal hands gripping his kneecaps so tightly his knuckles were white. He stared at the fourteen-year-old boy standing before him, the teacup in the boy’s hand perfectly still, not a single ripple disturbing the surface of the amber liquid.

 

"A Symbol of Victory," Toshinori repeated, the words tasting foreign on his tongue. He looked back at Nezu. "You want him to inherit One For All. You want me to pass the torch of the Ninth to a boy who... who talks like you."

 

"I am merely suggesting the most statistically optimal vessel for your Quirk, Yagi," Nezu replied cheerfully, hopping down from his chair and pouring himself another cup. "Your current trajectory has you dead within three years. You need a successor. Izuku possesses a heroic drive, a profound understanding of societal mechanics, and an intellect that surpasses anyone in your Rolodex of potential meathead candidates. The choice, ultimately, is yours."

 

Toshinori looked back at Izuku. The boy’s emerald eyes were unnerving. When Toshinori had looked into the eyes of his master, Nana Shimura, he had seen warmth, love, and unwavering hope. When he looked at Izuku Midoriya, he saw a supercomputer actively compiling data, calculating Toshinori’s pulse rate, oxygen intake, and muscular decay.

 

"Young Midoriya," Toshinori started, his voice rasping slightly. "Do you even know what One For All is? It is not a Quirk to be taken lightly. It is a sacred torch, passed down from generation to generation, accumulating power to defeat a great evil."

 

"A stockpiling Quirk merged with a transference Quirk," Izuku stated calmly, taking a slow sip of his chamomile tea.

 

Toshinori choked on his own saliva. "H-How—"

 

"It is the only logical conclusion," Izuku said, setting his cup down on his saucer with a soft clink. He walked over to a whiteboard, picked up a dry-erase marker, and began drawing a complex genetic diagram. "Your Quirk allows you to output kinetic energy that defies the laws of thermodynamics. However, your physique prior to UA—as documented in early medical records Nezu allowed me to review—was entirely unremarkable. Therefore, your Quirk is not an inherent mutation. Furthermore, your power level has demonstrably increased compared to your debut, implying an accumulation factor. Couple this with your frantic search for a 'successor,' a word you use literally rather than figuratively, and it necessitates a genetic transfer mechanism."

 

Izuku capped the marker and turned back to Toshinori, offering a perfectly polite, closed-eye smile.

 

"You possess a crystalline accumulation of power passed down through at least seven prior hosts, assuming an average tenure of ten to fifteen years per host based on the emergence timeline of Quirks. Am I incorrect, All Might?"

 

Toshinori stared at the whiteboard, then at the boy. He felt a cold sweat break out on his neck. "Eight," he whispered. "I am the Eighth."

 

"Fascinating," Izuku mused, his eyes flashing with genuine, terrifying curiosity. "And the 'great evil' you mentioned? I hypothesize it is an underground kingpin. Someone ancient. Someone with a Quirk capable of stealing and distributing other Quirks, which would necessitate the creation of a counter-Quirk like One For All."

 

Toshinori literally fell out of his chair. He scrambled backward, his skeletal frame hitting the floor with a thud. He pointed a trembling finger at Nezu. "Nezu! You told him about All For One?!"

 

"I assure you, Yagi, I did not," Nezu laughed, a bright, chiming sound. "He deduced the existence of the Boogeyman of the Underworld entirely on his own three days ago while analyzing the unnatural Quirk pairings in the Hosu City yakuza syndicates. I merely confirmed his hypothesis."

 

Toshinori pulled himself back up, his breathing shallow. He looked at the boy. Izuku wasn't gloating. He wasn't acting arrogant. He was simply stating facts, viewing the deepest, darkest secrets of the hero world as equations to be balanced.

 

"You..." Toshinori swallowed hard. "You really are Nezu’s son."

 

"I am Izuku Midoriya," the boy replied smoothly. "And I am willing to accept your Quirk, All Might. However, I require full disclosure on its cellular impact. If I am to act as a battery for eight generations of stockpiled kinetic energy, my current physical vessel is grossly inadequate. Without proper muscular and skeletal conditioning, the sudden influx of power would likely cause catastrophic tissue rupture, localized explosive dismemberment, and total central nervous system failure."

 

Toshinori just nodded numbly. "Yes. Your limbs would blow off."

 

"Then we have a great deal of work to do," Izuku said, adjusting his black tie. "When do we begin?"

 

 

 

The smell of salt, rotting kelp, and rust permeated the early morning air.

 

Dagobah Municipal Beach had once been a beautiful stretch of coastline. Now, it was a graveyard of broken appliances, rusted cars, and illegally dumped industrial waste. The sun was just beginning to peek over the horizon, casting long, jagged shadows across the mountains of trash.

 

Toshinori, in his skeletal form, stood on the pavement overlooking the beach. He held a thick stack of papers bound in a blue folder, his chest puffed out with a sense of traditional mentorly pride.

 

"This, Young Midoriya, is the American Dream Plan!" Toshinori announced, presenting the folder to Izuku. "I have calculated a ten-month physical conditioning regimen. By cleaning this beach, lifting these heavy appliances, and running through the sand, you will forge your body into a vessel capable of handling One For All!"

 

Izuku took the folder. He opened it. His emerald eyes scanned the first page, his pupils darting back and forth at a speed that made Toshinori slightly nauseous to watch.

 

Izuku flipped to the second page. Then the third.

 

By the fifth page, Izuku’s polite smile had vanished, replaced by a deep, disappointed frown. He closed the folder and handed it backward, not even looking.

 

A small, white paw reached out from inside Izuku’s oversized yellow backpack and took the folder. Nezu poked his head out of the bag, holding the American Dream Plan.

 

"Yagi," Nezu sighed, pulling a silver Zippo lighter from his trench coat.

 

Flick.

 

The flame ignited. Nezu casually set the American Dream Plan on fire, dropping the burning folder onto the concrete.

 

"Hey! My plan!" Toshinori squawked, waving his arms as the meticulously drawn schedules turned to ash.

 

"Your plan, All Might, is a fast track to muscular atrophy, micro-fractures in the skeletal structure, and severe caloric deficit," Izuku said, his voice flat. He stepped up to the railing, overlooking the trash. "You factored in my basal metabolic rate, but you completely failed to account for the exponential increase in caloric expenditure during the recovery phase of micro-tears in the muscle fibers. If I followed your meal plan while moving this tonnage, my body would cannibalize its own muscle tissue for energy by month three."

 

"But... but that's how I trained!" Toshinori protested weakly.

 

"You possessed a unique genetic anomaly that allowed your body to naturally adapt to the Quirk," Izuku countered, adjusting his sleeves. "I do not. I must engineer my body."

 

Nezu hopped out of the backpack, landing gracefully on the railing next to Izuku. He pulled out a thermos and two cups, pouring the morning tea.

 

"Furthermore, Yagi," Nezu added, handing a cup to his son, "simply picking up trash is a waste of Izuku’s intellect. Mindless physical labor is for grunts. Izuku is going to clear this beach, yes. But he is going to do it my way. The High Spec Optimization Plan."

 

"What does that entail?" Toshinori asked, feeling a migraine forming behind his eyes.

 

"Efficiency," Izuku answered. He took a sip of his tea, surveying the beach not as a chore, but as a resource. "I am going to use the beach to clear the beach."

 

Toshinori blinked. "I don't follow."

 

Izuku pointed a finger toward a rusted, half-buried pickup truck fifty yards away. "To move that truck by hand would require approximately 4,000 Newtons of continuous force. I currently max out at roughly 300 Newtons. Therefore, attempting to lift it is illogical. However, beside that truck is an abandoned commercial refrigerator containing intact compressor coils. Ten yards to the left is a pile of high-tensile steel cables from a collapsed suspension bridge. And right here..." Izuku kicked a rusted washing machine at his feet. "...is a functional electric motor."

 

Izuku turned to All Might, his eyes gleaming with the manic, terrifying light of a mad scientist.

 

"I am going to disassemble the garbage, All Might. I am going to build a pneumatic exoskeleton, a localized pulley nexus, and a motorized winch system. I will train my body by forging the tools required to conquer the environment, rather than letting the environment conquer me. I will be combining mechanical engineering with extreme weight training."

 

Toshinori looked at the fourteen-year-old. Then he looked at the smiling rat-bear-chimera sipping tea on the railing.

 

"You two," Toshinori whispered, deeply disturbed, "are absolute monsters."

 

"Thank you, All Might," Izuku smiled warmly. "I will require a welding torch, an angle grinder, and an uninterrupted supply of Earl Grey. I begin immediately."

 

 

 

The first four months were a grueling, bizarre spectacle that Toshinori could only watch in horrified fascination.

 

He had expected to mentor a boy crying through pushups. Instead, he found himself mentoring a teenage Tony Stark who operated on zero sleep and a terrifying amount of caffeine.

 

Izuku didn't just move trash; he systematically dismantled it.

 

On a blistering Tuesday in Month Two, Toshinori arrived at the beach in his muscle form, carrying a case of sports drinks. He found Izuku shirtless, covered in grease, sweat, and soot. The boy’s physique was already changing. The soft, rounded edges of a middle-schooler were melting away, replaced by the lean, tightly coiled muscles of a gymnast and a mechanic.

 

Izuku was currently strapped into a terrifying contraption. He had salvaged hydraulic pistons from a destroyed forklift and strapped them to his arms and legs using reinforced seatbelts and heavy leather straps. A small, loud generator sputtered on his back, belching black smoke.

 

"YOUNG MIDORIYA! WHAT IN THE NAME OF JUSTICE IS THAT?!" All Might boomed, dropping the sports drinks.

 

Izuku didn't flinch. He turned his head, his face obscured by a heavily tinted welding mask he had modified. "It is a rudimentary kinetic enhancer, All Might. The servos are wired to pressure plates in my boots and gloves. When I exert physical force, the hydraulics multiply my output by a factor of 4.5."

 

"Is that safe?!"

 

"Statistically? No," Izuku replied calmly. "There is a 34% chance the left elbow joint will fail and violently rupture my bicep. Which is why I am currently applying a counter-torque to the primary valve."

 

Izuku turned toward a massive, waterlogged sofa that easily weighed five hundred pounds. He squatted low, the hydraulics hissing and screaming in protest. His own organic muscles strained, veins popping on his forehead and shoulders.

 

"Calculated lift," Izuku muttered, his voice echoing mechanically from inside the mask. "Engaging."

 

With a sudden, violent hiss of compressed air, Izuku thrust upward. The heavy sofa flew into the air, traveling ten feet before crashing perfectly into the bed of a nearby rusted dump truck.

 

Izuku let out a sharp exhale, immediately reaching down to manually vent the pressure from the suit. Steam poured off his body. He unlatched the heavy machinery, letting the exoskeleton drop to the sand with a heavy thud, and grabbed a towel to wipe the grease from his face.

 

Toshinori was speechless. He deflated into his skeletal form in a puff of steam, coughing up blood. "Young Midoriya... you built a Quirk out of garbage."

 

"Support gear is merely the equalization of the biological playing field," Izuku said, taking one of the sports drinks and downing it mathematically, in three precise gulps to maximize hydration without causing stomach cramps. "Heroes rely too much on their biology. If your Quirk is erased, or if you reach your physical limit, what are you left with? I am ensuring that when I receive One For All, it is merely my primary weapon, not my only weapon."

 

Toshinori sat down on a nearby microwave, rubbing his eyes. "You know, when Nana trained me, she just had me punch a lot of trees."

 

Izuku paused, looking at Toshinori with a blank expression. "You punched trees."

 

"Yes. To build knuckle density."

 

"All Might," Izuku sighed, a sound that sounded painfully identical to Nezu dealing with a slow student. "Punching wood causes micro-fractures in the metacarpals. While it calcifies the bone, it severely damages the cartilage and nerve endings in your hands. Is that why you occasionally lose feeling in your pinky and ring fingers during cold weather?"

 

Toshinori froze. "How did you know that?"

 

"Because your grip strength on your left side diminishes by 8% when the ambient temperature drops below ten degrees Celsius. I noticed it when you signed the contract in the principal's office," Izuku said matter-of-factly. He picked up his welding torch. "I am building a pressurized hyperbaric chamber in my dorm to sleep in. It will increase oxygen saturation in my blood by 30%, accelerating my muscle recovery and bone density without destroying my joints. Now, if you'll excuse me, I have to recalibrate the winch. The tide is coming in, and I need to pull an engine block out of the surf."

 

Toshinori watched the boy walk away. He pulled out his phone and dialed a number.

 

"Hello?" Nezu’s cheerful voice answered.

 

"Nezu," Toshinori whispered into the receiver. "He's building a hyperbaric chamber out of a washing machine and an oxygen tank. I'm scared."

 

Nezu’s terrifying laughter echoed through the phone. "Isn't he magnificent, Yagi? He takes after his father!"

 

 

 

While his body was being forged on the beach, his mind was becoming a lethal instrument in the halls of UA.

 

By Month Six, Izuku was a known, and highly feared, entity among the faculty. He didn't act like a teenager. He acted like a phantom.

 

Shota Aizawa was walking down the empty corridor of the third floor late one Friday evening, his capture weapon loose around his neck, looking forward to a jelly pouch and three hours of uninterrupted sleep in his sleeping bag.

 

Clank.

 

Aizawa stopped. He slowly looked up.

 

The grate of the ceiling ventilation shaft was unscrewed. A split second later, a teenage boy dropped silently from the ceiling, landing in a perfect, shock-absorbing crouch directly in front of the underground hero.

 

Izuku stood up, dusting off his pristine black UA blazer. He was holding a file folder.

 

"Evening, Eraserhead," Izuku said politely.

 

Aizawa didn't flinch. He just stared at the boy with exhausted, bloodshot eyes. "Midoriya. Why are you in the vents?"

 

"Principal Nezu requested I optimize the airflow to his office. I found a dead pigeon in sector G-4, which was restricting HVAC efficiency by 4.2 percent. Also, the vents are the fastest route across campus without engaging in small talk with Present Mic."

 

Aizawa actually nodded at that. "Logical. I approve."

 

"I have a file for you," Izuku said, holding out the manila folder.

 

Aizawa took it, opening it warily. "What is this?"

 

"I was reviewing your patrol logs from the past three weeks," Izuku explained, clasping his hands behind his back. "You have been tracking a serial mugger in the Naruhata district. The local police believe his Quirk is localized teleportation because he vanishes from closed alleys. They are wrong."

 

Aizawa’s eyes narrowed, looking at the complex maps and algorithms Izuku had drawn in the file. "Explain."

 

"If he had a teleportation Quirk, there would be a sudden displacement of air pressure at his point of exit, which would register on the city's barometric sensors. There are no such spikes," Izuku stated smoothly. "The alleys he vanishes from all share a common architectural feature: old, pre-Quirk era sewage drainage pipes that connect directly to the subterranean maintenance tunnels. His Quirk isn't teleportation. It's a skeletal-compression mutation. He dislocates his own joints and slides down the drains."

 

Aizawa stared at the page, the realization hitting him like a truck. The kid had solved a three-week manhunt without ever leaving the campus.

 

"I've mapped out his likely trajectory based on the drainage flow," Izuku continued, offering a terrifyingly innocent smile. "If you wait at the outflow pipe on 4th Street at exactly 2:00 AM tonight, he will literally drop into your lap."

 

Aizawa closed the folder. He looked at Izuku. The boy’s posture was relaxed, but underneath the blazer, Aizawa could see the terrifying physical gains the kid had made. His shoulders were broad, his neck thick. He looked like a miniature, extremely polite assassin.

 

"You and Nezu," Aizawa muttered. "You're going to give the Hero Commission an aneurysm."

 

"That is the eventual goal, yes," Izuku nodded. "Have a pleasant patrol, Eraserhead."

 

Izuku turned, bent his knees, and leapt. With a terrifying display of pure, Quirkless leg strength, he grabbed the edges of the open vent ten feet above him, pulled himself inside with zero effort, and vanished into the darkness.

 

Aizawa stood in the hallway alone. He looked at the folder, then up at the vent.

 

"I need a raise," Aizawa sighed.

 

 

 

Despite his rapid ascent into terrifying competence, Izuku was still human. He was still a fourteen-year-old boy who had lost everything.

 

In Month Eight, on a rainy Sunday afternoon, Nezu found Izuku sitting on the floor of his room. The computer monitors were off. The blueprints for support gear were pushed aside. Izuku was just sitting there, staring at the charred photograph of him and his mother.

 

Nezu didn't announce his presence. He walked in silently, carrying a tray with a single cup of tea. He set it down on the desk and hopped onto the edge of Izuku’s bed.

 

For a long time, neither of them spoke. The sound of the rain lashing against the window was the only noise in the room.

 

"Today is her birthday," Izuku finally said. His voice wasn't shaking, but it was incredibly hollow. "She would have been forty-two."

 

Nezu folded his paws in his lap. "Do you miss her, Izuku?"

 

"Every second of every day," Izuku answered immediately, his eyes locked on the smiling face of Inko Midoriya. "I calculate what she would be doing right now. I imagine her making katsudon. I imagine her worrying about my scraped knuckles. It is a highly inefficient emotional loop."

 

"Grief is not an equation to be solved, my boy," Nezu said softly, his voice devoid of its usual manic cheer. "It is a permanent alteration of your psychological baseline. It changes the variables of your life forever. You cannot optimize grief, Izuku. You can only harness it."

 

Izuku slowly lowered the photograph. He looked at his hands. They were calloused, scarred from welding burns and lifting rusted steel. They were the hands of a warrior, not the soft hands of the boy his mother had known.

 

"I remember the day I was taken from my cage," Nezu spoke, his dark eyes looking out the window, staring into a past only he could see. "The scientists who experimented on me... they thought I was just an animal. They inflicted unimaginable pain to test the limits of my intelligence. When I finally outsmarted their security systems and broke free, I stood in the rain, much like today. I was entirely alone. I hated humanity. I wanted to burn their society to the ground."

 

Izuku looked up at his adoptive father. He had never heard Nezu speak of his past so openly.

 

"But I realized something," Nezu continued, looking back at Izuku. "Burning the world is easy. Any villain with a fire Quirk can do it. Rebuilding the world, taking control of the board and forcing the system to bend to your will... that requires true power. I did not let my trauma break me. I forged it into a weapon. I became the principal of the very institution that produces the heroes who once looked down on me."

 

Nezu hopped down from the bed and walked over to Izuku. He placed a small, warm paw on the boy’s shoulder.

 

"Your mother loved you, Izuku. She loved the kind, gentle boy you were. But the world took her away because the world is careless. You do not honor her memory by remaining weak. You honor her by becoming so strong, so intelligent, and so terrifyingly capable that no one will ever be careless around you again."

 

Izuku felt a warmth spread through his chest, thawing the cold, heavy stone that had resided there for eight months. He looked at Nezu. He saw the scars on the principal's face, mirrored by the unseen scars on his own heart.

 

Izuku carefully placed the photograph in his desk drawer, right next to a pristine, polished silver pocket watch Nezu had given him.

 

"I am ready for the final phase of training, Principal Nezu," Izuku said, his voice ringing with absolute, unshakeable resolve. "I will not let her death be a meaningless statistic."

 

Nezu smiled—a genuine, soft smile. "I know you won't, my son. Now, drink your tea. We have a beach to finish."

 

 

 

Month Ten.

 

The morning of the UA Entrance Exam.

 

Toshinori Yagi stood at the top of the concrete stairs leading down to Dagobah Beach. The sun was just cresting the horizon, painting the sky in brilliant hues of gold and violet.

 

The beach was unrecognizable.

 

The mountains of trash, the rusted cars, the rotting appliances—they were entirely gone. In their place was a pristine expanse of white sand, untouched by human negligence. The ocean waves crashed gently against the shore, clean and clear.

 

But Izuku hadn't just removed the trash. He had repurposed it.

 

At the far end of the beach sat a massive, highly organized staging area. Izuku had used the scrap metal to build a series of complex recycling compactors, sorting the garbage into neat, perfect cubes of raw materials that were currently waiting to be picked up by a municipal salvage company. It was a marvel of mechanical engineering and logistical planning.

 

And standing atop the highest cube of compacted steel, silhouetted against the rising sun, was Izuku Midoriya.

 

Toshinori walked down the stairs, his breath catching in his throat.

 

Izuku jumped down from the ten-foot cube, landing with a heavy, powerful thud that kicked up sand, absorbing the impact with flawlessly bent knees.

 

He was wearing a black tank top and dark cargo pants. The fourteen-year-old boy was gone. In his place stood a young man forged in iron and intellect. Izuku’s arms were thickly muscled, defined by heavy, corded veins. His shoulders were broad, his chest solid. He moved with a predatory grace, his balance perfect, his center of gravity flawlessly aligned.

 

But it wasn't just his body that had changed. It was his aura.

 

When Izuku looked at Toshinori, the Number One hero felt a primal shiver run down his spine. The boy’s emerald eyes were sharp, calculating, missing absolutely nothing. He didn't exude the warm, blinding light of All Might. He exuded the cold, unstoppable pressure of a tidal wave.

 

"Good morning, All Might," Izuku said politely, wiping sweat from his brow with a towel. "I have completed the High Spec Optimization Plan. The beach is clear, the materials are sorted for municipal resale, and my body fat percentage is currently sitting at an optimal 7.2 percent. My skeletal density has increased by forty percent due to the hyperbaric conditioning."

 

Toshinori stared. He literally couldn't find the words. He remembered training for One For All. He had just moved fridges. This kid had optimized a city's waste management system to build a superhero physique.

 

"Young Midoriya," Toshinori finally managed to say, his voice thick with profound awe. "You... you have exceeded every possible expectation. You didn't just clear the beach. You conquered it."

 

Izuku offered a small, terrifyingly calm smile. "I merely applied logic to a physical problem. Brute force is useless without direction."

 

Toshinori suddenly felt incredibly inadequate as a mentor. He had taught this boy nothing about physical combat. Nezu had taught him everything. All Toshinori was doing was handing over a battery.

 

But as he looked at Izuku, Toshinori realized Nezu had been right. If One For All was given to a traditional hero, they would fight the League of Villains and All For One with their fists.

 

Izuku Midoriya would fight them with his mind. And he would tear them apart.

 

Toshinori stood up straight, his skeletal form suddenly bursting into a massive cloud of steam. The muscular, towering form of All Might emerged, his golden hair catching the morning light, his trademark smile plastered across his face.

 

"You have proven yourself, Young Midoriya!" All Might boomed, his voice echoing across the empty beach. "Your body is a perfect vessel! Your mind is a fortress! It is time for you to receive the sacred power of the Ninth!"

 

Izuku stood at attention, his hands clasped behind his back, waiting. He expected a grand ceremony. He expected to be handed a glowing orb of energy, or perhaps an intricate blood ritual.

 

All Might reached up, his massive fingers plucking a single, thick strand of golden hair from his bangs. He held it out toward Izuku, his smile unwavering.

 

"EAT THIS!" All Might declared dramatically.

 

Izuku stared at the hair.

 

He stared at All Might’s smiling face.

 

The ocean breeze blew softly, rustling the nearby palm trees.

 

Izuku didn't move. His analytical mind, capable of hacking national mainframes and solving cold-case murders in his sleep, ground to a violently abrupt halt.

 

"I beg your pardon?" Izuku asked, his voice entirely flat.

 

"Eat it!" All Might repeated, thrusting the hair closer. "To inherit my power, you must consume my DNA! That's how the Quirk transfers!"

 

Izuku slowly brought his hands from behind his back. He pinched the bridge of his nose, closing his eyes. For a brief, fleeting second, Toshinori saw the ghost of the exasperated underground hero, Aizawa, superimposed over the boy.

 

"All Might," Izuku sighed deeply, his voice laced with the infinite patience of a scientist dealing with an absolute moron. "Are you telling me that the pinnacle of heroic power, the sacred torch passed down through eight generations to combat the ultimate evil... is transmitted via oral ingestion of keratin and dead skin cells?"

 

"Uh... yes?" All Might faltered, his smile twitching.

 

"Do you have any idea how unhygienic that is?" Izuku asked, his eyes snapping open, glaring at the hero. "Hair is notoriously difficult to digest. Furthermore, if DNA transfer is the only requirement, a sterile blood transfusion or a mucosal swab would be vastly safer and have a higher absorption rate."

 

"Listen, kid, I don't make the rules!" All Might sweatdropped, looking incredibly uncomfortable. "Just eat the hair! The Entrance Exam starts in three hours! You need time to digest it!"

 

Izuku stared at the hair for another long moment. He sighed again, a sound of profound suffering.

 

"Fine. But I am chasing it with tea."

 

Izuku snatched the hair from All Might’s fingers. He pulled a thermos from his backpack, popped the hair into his mouth like a pill, and took a massive swig of Earl Grey, swallowing hard.

 

He stood there for a moment, blinking.

 

"I feel absolutely nothing," Izuku reported. "Aside from a mild texture aversion."

 

"It takes a few hours to metabolize!" All Might laughed nervously, shrinking back down into his skeletal form. "You should feel it kick in during the exam."

 

Izuku picked up his backpack, slinging it over one massively muscled shoulder. "Let us hope so. I have engineered several support items for the exam, but having a kinetic battery will drastically expand my tactical options."

 

He turned and began walking up the stairs, leaving the Symbol of Peace standing on the pristine beach.

 

Toshinori watched him go. The boy didn't look back. He was already pulling out a tablet, his fingers flying across the screen as he calculated his final strategies for the UA Entrance Exam.

 

Toshinori pulled out his phone. He dialed Nezu.

 

"He ate it," Toshinori said weakly.

 

"Excellent!" Nezu cheered over the phone. "The board is set, Yagi. The pieces are moving. Now, we get to watch my son completely break the UA exam protocols."

 

Toshinori hung up. He looked out at the ocean, a profound sense of both hope and terror washing over him.

 

The Symbol of Peace had just given the power of a god to the mind of a rat.

 

God help the villains.
