what if Deku and all might Were Brothers

 

The smell of grilled mackerel, steaming white rice, and rich miso soup drifted through the cramped but cozy hallway of the Midoriya apartment. It was a familiar, comforting scent, the kind that promised a normal, mundane Tuesday.

 

Fourteen-year-old Izuku Midoriya sat at the small dining table, his thumbs flying across the screen of his smartphone. His green eyes were wide, reflecting the bright screen as he watched a shaky, amateur video of a villain fight in Tatooin Station.

 

"Wow," Izuku muttered under his breath, his free hand instinctively reaching for the scorched, dog-eared notebook sitting next to his chopsticks. "Kamui Woods has really improved his response time. If he leads with his Lacquered Chain Prison, he can minimize collateral damage to the surrounding infrastructure... but wait, if Mt. Lady intervenes, her size could disrupt the structural integrity of the overpass—"

 

"Muttering again, Izu?"

 

A raspy, incredibly fond voice broke through Izuku’s intense concentration.

 

Izuku snapped his head up, a bright, gap-toothed smile breaking across his freckled face. "Ah! Morning, Toshi-nii!"

 

Stepping out of the small guest room was a towering, skeletal figure. Toshinori Yagi, Izuku’s older half-brother, looked like a stiff breeze could knock him over. He wore a pair of oversized grey sweatpants and a white t-shirt that hung off his sharp, jutting collarbones like a sheet draped over a coat rack. His messy, spiky blonde hair defied all logic and gravity, two prominent bangs hanging over his sunken, shadowed face.

 

Despite his gaunt appearance, which often frightened strangers on the street, Toshinori’s piercing blue eyes were incredibly warm as they landed on his little brother.

 

The age gap between them was vast—more than two decades. They shared the same mother, Inko, though they looked nothing alike. Toshinori was the product of Inko’s brief, early first marriage, long before she met Hisashi Midoriya. Due to the massive gap in their ages, Toshinori had always been less of a traditional brother and more of a surrogate father to Izuku, especially after Hisashi took a permanent post overseas and drifted out of their lives.

 

Toshinori shuffled into the kitchen, his joints popping audibly. He reached out with a massive, bony hand and mercilessly ruffled Izuku’s unruly green curls.

 

"Hey! Toshi-nii, my hair!" Izuku laughed, batting at his brother’s wrist, though he leaned into the touch.

 

"It looks exactly the same as it did before I touched it," Toshinori teased, his voice a low, gravelly rumble. He pulled out a chair opposite Izuku and sat down heavily, releasing a long sigh.

 

From the stove, Inko Midoriya turned around, a spatula in hand and a deep frown creasing her forehead. "Toshinori, you sound terrible. Did you sleep at all last night?"

 

"I slept fine, Mom, really," Toshinori lied smoothly, offering a weak smile. "The couch is very comfortable."

 

"You shouldn't be sleeping on the couch! We have a perfectly good air mattress," Inko scolded, plating a piece of mackerel and setting it in front of her eldest son. She reached out, gently cupping his hollow cheek. "You’ve lost more weight. Are they feeding you at that agency?"

 

Izuku leaned forward, eyes sparkling. "Are you working on a big case, Toshi-nii? You said you do administrative work for the Might Tower! Have you seen All Might recently? Did he come into the office? Is he working on the Water Hazard case in Roppongi?"

 

Toshinori suddenly whipped his head to the side, bringing a paper napkin to his mouth as a violent, wracking cough seized his chest. His massive shoulders shook as he hacked, the sound wet and painful. When he finally pulled the napkin away, Izuku caught the faintest glimpse of a red stain before Toshinori crumpled the paper in his massive fist.

 

"Toshinori!" Inko gasped, rushing over with a glass of water.

 

"I'm fine, I'm fine," Toshinori wheezed, taking the glass with trembling fingers. He forced a smile, though it looked strained. "It's just that old ulcer acting up again. Too much coffee, not enough sleep. You know how office work is."

 

Izuku’s excitement instantly deflated, replaced by a heavy knot of worry. "You work too hard, Toshi-nii. You're always commuting, and you always come home looking so exhausted. You shouldn't push yourself just for paperwork."

 

Toshinori looked at his little brother’s genuine, anxious expression. A profound, aching guilt twisted in his chest. If you only knew, my boy, he thought. If you only knew the truth.

 

For his entire life, Toshinori had maintained a massive, intricate lie. His family believed he was a low-level secretary and administrative assistant at Sir Nighteye’s and later All Might's hero agencies. It explained his strange hours, his constant absences, and his encyclopedic knowledge of hero laws. It was a perfect cover.

 

He could never tell them the truth. He could never tell the gentle mother who worried over his every cough, or the starry-eyed little brother who worshipped heroes, that he was the Symbol of Peace. He was All Might.

 

The secret wasn't born of malice, but of absolute terror. Five years ago, his battle with the demon king of the underworld, All For One, had cost him his stomach, part of his respiratory system, and nearly his life. If his enemies ever discovered that Toshinori Yagi, a Quirkless nobody who inherited a god-like power, had a frail mother and a Quirkless, defenseless little brother... they would be slaughtered in a heartbeat. The villains would use Inko and Izuku to break him.

 

So, he remained just 'Toshi-nii'. The sickly, overworked, deeply loving older brother.

 

"I have to work hard, Izu," Toshinori said softly, his blue eyes softening. He reached into the pocket of his baggy sweatpants and pulled out a crisp 5000-yen note, sliding it across the table. "How else am I going to fund your endless supply of hero notebooks?"

 

Izuku’s face flushed a brilliant red. "T-Toshi-nii! I don't need—!"

 

"Take it," Toshinori insisted, his tone gentle but leaving no room for argument. "You told me last night you were on volume thirteen, right? Buy a nice one with a sturdy cover. And maybe treat yourself to a crepe on the way home."

 

Izuku looked at the money, then at his brother. He carefully folded the bill and put it in his uniform pocket. "Thank you, big brother."

 

"Anytime, kiddo." Toshinori picked up his chopsticks, forcing himself to eat a bite of the fish despite the nausea churning in his ruined abdomen. He needed the calories. He had three hours of hero work to squeeze in today before his time limit ran out entirely.

 

Izuku checked his phone and gasped. "I'm going to be late! I have to go!" He grabbed his yellow backpack, hastily shoving his notebook inside.

 

"Have a good day at school, Izuku!" Inko called out, untying her apron. "Be careful on the crossing!"

 

Toshinori stood up, his towering frame casting a long shadow in the small kitchen. He walked Izuku to the entryway, leaning against the doorframe as Izuku furiously tied his red sneakers.

 

"Hey," Toshinori said quietly.

 

Izuku looked up.

 

"Is... everything alright at school?" Toshinori asked, his brow furrowing slightly. He had noticed the way Izuku sometimes flinched, the occasional bruises he tried to hide under long sleeves, the burn marks on the shoulders of his uniform that Izuku blamed on 'chemistry class accidents.' Toshinori wasn't stupid. He knew what society thought of the Quirkless. He remembered it all too well from his own youth.

 

Izuku froze for a fraction of a second, his green eyes darting away. Then, he beamed, a perfect, practiced smile. "Everything is great, Toshi-nii! Just studying hard for the high school entrance exams!"

 

Toshinori’s jaw tightened, but he didn't press. He reached out and adjusted the collar of Izuku’s black uniform, smoothing out the fabric. "If anyone ever gives you trouble, you tell me, okay? I know I just push papers, but I can still come down there and give a teacher a piece of my mind."

 

Izuku’s heart squeezed. He knew his brother was sickly and frail. The thought of Toshinori trying to stand up to someone like Katsuki Bakugo was terrifying. I have to protect him from that, Izuku thought. He worries enough.

 

"I know, Toshi-nii. But I'm fine! Really!" Izuku opened the door, the bright morning sunlight flooding the entryway. "See you tonight! We can watch the All Might documentary that airs at eight!"

 

Toshinori chuckled, a genuine, warm sound. "I wouldn't miss it for the world. Stay safe, Izu."

 

Izuku waved, sprinting down the hallway of the apartment complex. Toshinori watched him go until he disappeared down the stairs. The moment the boy was out of sight, Toshinori slumped against the doorframe, a violent fit of coughing overtaking him. He pressed his hand against his left side, right over the grotesque, spider-webbing scar that covered half his torso.

 

I will protect that smile, Toshinori thought fiercely, closing his eyes against the pain. With the last drop of blood in my veins, I will keep him safe.

 

The warmth of the morning evaporated the moment Izuku stepped into the classroom of Aldera Junior High.

 

Here, he wasn't a beloved little brother. He wasn't 'Izu'. Here, he was a smudge on the bottom of a shoe. He was a mistake of genetics, a relic of a bygone era.

 

He was a Deku.

 

Izuku kept his head down as the teacher droned on about career paths, his pencil flying across the pages of his newly minted Hero Analysis for the Future, No. 13. He was currently sketching the water-manipulation Quirk of a new sidekick he’d seen on the news, trying to ignore the sinking feeling in his gut.

 

"Since you're all third years, it's time for you to think seriously about your futures!" the teacher announced, slapping a stack of career aptitude papers on his desk. "I would hand out these printouts, but..." The teacher suddenly grabbed the papers and threw them into the air, laughing as they fluttered down over the students. "Why bother?! You're all planning to go into the hero course anyway, right?!"

 

The classroom erupted. Students leaped from their desks, showing off glowing hands, stretching limbs, and minor telekinetic feats. The noise was deafening, a cacophony of pride and arrogance.

 

Izuku kept his head down, raising a single, timid hand. He didn't activate a Quirk. He had nothing to show.

 

"Yes, yes, you all have wonderful Quirks!" the teacher said over the noise. "But remember, using your powers in school is against the rules!"

 

"Hey, teach!"

 

The loud, arrogant voice cut through the noise like a knife. The classroom fell silent instantly.

 

Sitting in the back row, his feet kicked up on his desk, was Katsuki Bakugo. His ash-blonde hair bristled like an angry hedgehog, and a cocky, cruel smirk played on his lips. "Don't lump me in with this bunch of losers. I'm not gonna be stuck at the bottom with the rest of these rejects."

 

The class erupted in angry protests, but Bakugo just laughed, small explosions popping in the palms of his hands. "Bring it on, extras!"

 

"Ah, Bakugo, you're aiming for U.A. High, aren't you?" the teacher noted, looking at his clipboard.

 

A collective gasp swept through the room. "U.A.?! The national school? The acceptance rate is like, 0.2 percent!"

 

"That's exactly why it's the only place worthy of me," Bakugo declared, standing up and puffing out his chest. "I aced the mock test! I'm the only one at this crappy school who has a chance! I'm gonna surpass All Might and become the top hero, and I'll carve my name into the annals of history!"

 

"Oh, right," the teacher added, casually glancing at his notes. "Midoriya, didn't you also apply for U.A.?"

 

Izuku’s blood ran cold. He froze, his pencil snapping in his grip.

 

The entire classroom went dead silent. For one agonizing second, no one moved. And then, the room exploded into uproarious laughter.

 

"Midoriya? No way!"

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

"He's Quirkless! What's he gonna do, take notes at the villains?"

 

"Th-They got rid of that rule!" Izuku stammered, standing up defensively, his knees shaking. "There's no precedent, but I could be the first—!"

 

CRASH!

 

Izuku’s desk was blown backward. He fell to the floor, coughing as smoke filled his lungs. Looming over him was Bakugo, his hand smoking, his red eyes burning with absolute fury.

 

"Listen up, Deku," Bakugo snarled, stepping closer, casting a terrifying shadow over Izuku. "You're even worse than the rest of these rejects. You're Quirkless. You have no power. You think you can rub shoulders with me?!"

 

"N-No! Wait, Kacchan! It's not like I'm trying to compete with you!" Izuku scrambled backward until his back hit the wall. "It's just... it's been my dream since I was little. And... and there's no harm in trying, right?"

 

"Try?! What can you even do?!" Bakugo yelled. "You'll die in the exams! You're just a liability!"

 

The teacher did nothing. He just watched, slightly bored, as the class laughed. Izuku bit his lip, looking away. His chest ached. Toshi-nii... if you were here... you'd tell them to stop. You'd tell them I can do it.

 

But his brother wasn't here. It was just Izuku, alone in a world that despised him.

 

The rest of the day passed in a blur of humiliation. When the final bell rang, Izuku lingered behind, staring at the news feed on his phone. The Tatooin Station incident was over. Mt. Lady had stolen the credit. Izuku sighed, opening his notebook to finish his entry.

 

Suddenly, a hand snatched the notebook from his desk.

 

Izuku gasped. "Hey!"

 

Bakugo stood there, holding Hero Analysis for the Future, No. 13. Two of his lackeys flanked him.

 

"We're not done talking, Deku," Bakugo sneered, waving the notebook.

 

"Kacchan, give it back!" Izuku pleaded, reaching for it. That was the notebook his brother had paid for just this morning.

 

Bakugo slammed his palms together, sandwiching the notebook. A fierce, concussive explosion rattled the windows.

 

Izuku screamed.

 

When Bakugo pulled his hands apart, the notebook was charred, smoking, and ruined. With a cruel, dismissive toss, Bakugo threw it out the open window. It landed with a pathetic splash in a koi pond three stories below.

 

Izuku stared in horror. His notes. The gift from his brother. Destroyed in an instant.

 

"Most top-tier heroes have stories about their school days," Bakugo said, leaning in close, his voice a dangerous purr. "Stories about how they were the only ones from their mediocre middle schools to make it big. I'm a perfectionist, Deku. I want to be the only one from this garbage heap to get into U.A. It ruins my origin story if a Quirkless loser like you gets in too."

 

Bakugo placed a heavy, smoking hand on Izuku’s shoulder. The heat bled through his uniform, burning his skin. Izuku squeezed his eyes shut, trembling violently.

 

"So, forget about U.A., nerd," Bakugo whispered. He turned and walked toward the door, his lackeys snickering behind him.

 

As he reached the doorway, Bakugo paused, looking over his shoulder. A vicious, soulless smirk crossed his face.

 

"If you really want to be a hero that badly, there's a quick way to do it," Bakugo said smoothly. "Believe that you'll be born with a Quirk in your next life, and take a swan dive off the roof of the building!"

 

Izuku stopped breathing. The words hung in the air, venomous and lethal. He turned, his fists clenched, intending to say something, anything. But Bakugo just raised a hand, sparks crackling threateningly from his palm.

 

Izuku froze. The fight drained out of him. He was powerless.

 

He walked down to the courtyard in a daze. He waded into the koi pond, his shoes sinking into the mud, and pulled the soggy, ruined notebook from the water. He brushed a fish away.

 

"Stupid," Izuku whispered, tears finally spilling over his eyelashes. "Stupid, stupid, stupid. If I really jumped... that would be instigating suicide. You'd ruin your own chances, Kacchan."

 

He hugged the wet notebook to his chest. The image of Toshinori’s tired, smiling face flashed in his mind.

 

I'm sorry, Toshi-nii, Izuku thought, his tears mixing with the pond water dripping from the book. You gave me money for this, and I couldn't even protect it. How can I be a hero when I can't even stand up for myself?

 

Izuku took the long way home. He didn't want to go back to the apartment just yet. He didn't want Inko to see his tear-stained face, or his burnt shoulder, or his muddy shoes. He definitely didn't want Toshinori to see him like this. His brother already carried too much weight on his shoulders. He didn't need to add a pathetic, bullied little brother to the list.

 

He found himself walking under a massive bridge, the concrete underpass dark and echoing. He practiced his fake smile, forcing his lips into a wide, unnatural grin.

 

Ha... ha... ha... he forced a quiet laugh, trying to mimic the booming, fearless laugh of his idol, All Might. I'm fine. I'm totally fine. I'll just tape the notebook back together. Toshi-nii won't even notice.

 

He didn't hear the wet, squelching sound behind him until it was too late.

 

"A medium-sized invisibility cloak," a gurgling, wet voice hissed from the shadows.

 

Izuku spun around, his eyes widening in absolute terror.

 

Rising from the manhole cover was a monstrous mass of dark, foul-smelling sludge. It had no solid form, just a chaotic, shifting mass of mud and slime, with two massive, bulging eyes and a jagged set of teeth floating within the muck.

 

Before Izuku could scream, the villain lunged.

 

A heavy, suffocating mass of sludge slammed into Izuku, knocking him to the pavement. In an instant, the slime wrapped around his limbs, pinning his arms to his sides. The villain surged upward, forcing itself into Izuku’s mouth, down his throat, filling his nose.

 

"Don't worry," the villain purred, its voice echoing inside Izuku’s skull. "I'm just taking over your body. It'll only hurt for about forty-five seconds. Then, it'll all be over."

 

Izuku thrashed wildly, his fingers clawing at the sludge. It was like trying to grab water. His nails scraped uselessly through the muck.

 

I can't breathe! Izuku’s mind screamed. The foul taste of sewage and rot filled his mouth. His lungs burned, screaming for oxygen that wasn't there. He kicked his legs, trying to find purchase, but the villain lifted him entirely off the ground.

 

"You're my hero," the sludge villain laughed, tightening its grip. "I didn't think he'd track me down so fast. I need a disguise, kid. Just let it happen."

 

Izuku’s vision began to blur, black spots dancing at the edges of his sight. The pain in his chest was agonizing. He felt his consciousness slipping away.

 

Is this... it? he thought, his struggling growing weaker. Am I going to die here? Like this?

 

Faces flashed before his dying eyes. His mother, Inko, weeping at his funeral. And Toshinori.

 

Toshi-nii... Izuku’s heart broke. He's going to be so sad. He's going to blame himself. I never got to say goodbye. I never got to be a hero.

 

A tear slipped from Izuku’s eye, mingling with the sludge. He closed his eyes, surrendering to the dark.

 

Suddenly, a metallic clang echoed through the tunnel.

 

The manhole cover, completely detached from its rim, flew through the air and slammed into the ceiling of the underpass.

 

"HAVE NO FEAR, YOU ARE SAFE!"

 

A voice boomed through the tunnel. It wasn't the gurgling voice of the villain. It was a voice that Izuku had heard a thousand times on television, on his computer, in his dreams. It was a voice that commanded the very air around it, vibrating with absolute, unshakeable confidence.

 

"NOW THAT I AM HERE!"

 

Izuku forced his eyes open a fraction of a millimeter.

 

Standing at the entrance of the tunnel, backlit by the afternoon sun, was a colossus. A man built of pure, unadulterated muscle, wearing a simple white t-shirt and green cargo pants. His golden hair stood tall in two massive bangs.

 

All... Might? Izuku’s brain short-circuited. The Number One Hero? Here?!

 

The sludge villain screeched in panic. "Damn you!" The villain whipped a tendril of sludge forward like a spear, aiming straight for the hero's chest.

 

All Might didn't even flinch. He simply planted his feet, drew his fist back, and threw a punch at the empty air.

 

"TEXAS SMASH!"

 

The air pressure generated by the sheer physical force of the punch was apocalyptic. A localized hurricane exploded within the tunnel. The wind tore through the underpass, ripping the sludge villain apart on a molecular level. The slime was blasted off Izuku, splattering violently against the concrete walls.

 

Freed from the suffocating mass, Izuku gasped, inhaling a desperate, ragged breath of air. The force of the wind threw him backward, and he hit the ground, his vision spinning into total darkness.

 

Smack. Smack. Smack.

 

"Hey! Wake up! Hey!"

 

Izuku groaned, his eyelids fluttering. His cheek stung slightly. Someone was tapping his face. He blinked against the bright light, his vision slowly coming into focus.

 

Looming over him, casting a massive shadow, was a jawline carved from granite and a blinding, heroic smile.

 

"Ah! Good! You are awake!" All Might boomed, stepping back and placing his hands on his hips. "I was worried I had hit you too hard with the air pressure! Apologies for getting you caught up in my villain hunt! I don't usually make mistakes like this, but I'm in a new city and got a little turned around! HA HA HA HA!"

 

Izuku scrambled backward, his mouth hanging open so wide his jaw popped.

 

He was dreaming. He had died, and this was heaven. Or he was hallucinating from oxygen deprivation.

 

It's him! Izuku thought, his fanboy instincts overriding his shock. It's the real All Might! He looks completely different in person! He's so big! The physical presence is overwhelming!

 

"Well, I've safely contained the villain!" All Might said, holding up two large, plastic soda bottles filled to the brim with angry, shifting sludge. "Thanks to you, civilian!"

 

"Ah! I—I need an autograph!" Izuku scrambled, feeling the wet pavement around him. "Where is my notebook?!"

 

He spotted his ruined, soggy notebook lying a few feet away. He grabbed it, frantically flipping through the wet pages to find a blank one. But as he turned to the middle, his jaw dropped.

 

There, written in massive, bold, sweeping strokes across two entire pages, was All Might’s signature.

 

"HE ALREADY SIGNED IT!" Izuku shrieked, bowing repeatedly, his head nearly hitting the concrete. "Thank you! Thank you! It will be a family heirloom! I'll pass it down for generations!"

 

"HA HA HA! Excellent!" All Might gave a thumbs-up. Then, he turned away, stretching his massive legs. "Well, I must be off to turn this fellow into the authorities! Stay out of trouble, kid!"

 

"Wait!" Izuku gasped, scrambling to his feet. "Already? But... I have so many questions!"

 

"Pro heroes are constantly fighting time as well as enemies!" All Might called out over his shoulder. He crouched down, the concrete beneath his boots cracking under the sheer tension of his muscles. "Thanks for your support!"

 

No! Izuku panicked. I can't let him go! Not yet! I have to know! I have to ask him!

 

Before his rational brain could stop his body, Izuku sprinted forward. As All Might leaped into the sky with explosive force, Izuku lunged, wrapping his arms around the hero's thick, muscular calf.

 

The world vanished in a blur of speed and wind. The G-force nearly ripped Izuku's arms out of their sockets. He screamed in terror as the ground fell away, the city of Musutafu shrinking into a sprawling grid of toy blocks below them.

 

"Hey, hey, hey!" All Might yelled, looking down in absolute shock. "What are you doing?! Let go! Your fanaticism is too much!"

 

"If I let go now, I'll fall to my death!" Izuku screamed over the roaring wind, his eyes squeezed shut, tears streaming horizontally across his face.

 

All Might froze. "Right. Good point."

 

All Might reached down, grabbing the collar of Izuku’s uniform to ensure he wouldn't slip. As he did, a sharp, agonizing spike of pain shot through All Might’s left side.

 

Dammit, Toshinori thought, his heroic smile faltering for a fraction of a second. I've reached my limit. I have less than a minute left before the transformation breaks. I need to land, now!

 

Desperately scanning the skyline, All Might spotted a nondescript, empty commercial building with a flat roof. He altered his trajectory, the wind whistling past his ears, and brought them down fast.

 

They hit the roof with a heavy thud.

 

Izuku instantly collapsed onto the gravel, trembling violently. "My life flashed before my eyes..." he whimpered, clutching his chest.

 

"Good grief," All Might sighed, wiping a bead of sweat from his brow. His massive chest heaved, and he felt the familiar, ominous bubbling of blood in his throat. "That was incredibly reckless, young man! You should speak to the people downstairs and have them escort you out. I must be going!"

 

All Might turned toward the edge of the roof.

 

He's leaving, Izuku thought. The desperation surged back, thicker and heavier than before. Bakugo’s cruel laughter echoed in his ears. The pitying looks of his teachers. The apologies of the doctor who diagnosed him as Quirkless.

 

"Wait!" Izuku yelled, squeezing his eyes shut.

 

"No! I will not wait!" All Might yelled back, gripping the railing. I can't! I'm out of time!

 

"Even if I don't have a Quirk...!" Izuku screamed to the sky, his voice cracking with all the pain and longing he had carried for a decade.

 

All Might stopped dead in his tracks. The word 'Quirkless' acted like a physical blow. He froze, his hand tightening on the metal railing.

 

Izuku stood up, trembling, his hands clenched into fists at his sides. He kept his eyes locked on the broad, heroic back of his idol.

 

"Can someone without a Quirk be a hero like you?!"

 

The wind howled across the empty rooftop. The city traffic buzzed far below, indifferent to the boy baring his soul to the heavens.

 

"Because I don't have a Quirk," Izuku continued, his voice trembling, tears welling in his eyes. "I'm constantly mocked. Everyone thinks I'm a loser. Everyone tells me to give up. But... I think saving people is the coolest thing in the world. I want to save people with a fearless smile! I want to be the greatest hero, just like you!"

 

Izuku finally opened his eyes, expecting to see the towering figure of All Might looking down at him with an answer.

 

Instead, he saw a massive cloud of thick, white steam.

 

Izuku blinked, confused. The steam billowed wildly, obscuring the space where the Number One Hero had been standing just a second ago.

 

"H-Huh?" Izuku muttered. "An explosion? Where did All Might go? Is this a trick? A sidekick's Quirk?"

 

As the steam slowly dissipated, rolling away on the rooftop breeze, a figure emerged.

 

Izuku’s heart stopped.

 

He didn't see the towering colossus of muscle. He saw a man hunched over, coughing violently into his hand. The man was terribly skinny, dressed in baggy green cargo pants and a white t-shirt that hung off his skeletal frame. His messy, spiky blonde hair hung over his sunken face.

 

The man wiped his mouth, and Izuku saw the smear of bright red blood on his chin.

 

Izuku’s brain completely, utterly flatlined.

 

He knew that white t-shirt. He had seen it this morning, at his kitchen table. He knew that messy blonde hair. He had ruffled it. He knew that awful, hacking cough, the one his mother always tried to cure with tea and throat lozenges.

 

The skeletal man turned around, wiping the blood from his chin, his piercing blue eyes meeting Izuku’s wide, terrified green ones.

 

For ten seconds, neither of them moved. The silence was absolute.

 

Toshinori Yagi stared at the boy standing across the roof. His mind, usually sharp and tactical, went entirely blank.

 

Oh god, Toshinori thought, a wave of sheer, unadulterated horror washing over him. No. No, no, no.

 

Izuku took a step back, his hands flying to his mouth. "Y-You... you're fake. You're an imposter! You deflated! Where is All Might?!"

 

Toshinori opened his mouth, but only a raspy wheeze came out. He raised his bony hands in a placating gesture, his blue eyes wide with panic. "Izu—"

 

He stopped himself. He had almost called him by his nickname.

 

But Izuku heard it. The cadence. The raspy, gentle tone of the voice. It wasn't the booming baritone of the Symbol of Peace. It was the voice of the man who had bought him his hero notebook just eight hours ago.

 

"No," Izuku whispered, his legs giving out. He fell to his knees on the gravel, staring at the gaunt man in front of him.

 

The sharp cheekbones. The shadows under the eyes. The oversized clothes. The constant exhaustion. The 'administrative' job at the hero agency. The sudden 'ulcer' attacks whenever a major villain incident occurred on the news.

 

The pieces fell together with the force of a collapsing skyscraper.

 

"T... Toshi... nii?" Izuku choked out, the word tearing out of his throat like a sob.

 

Toshinori flinched as if he had been shot. His shoulders slumped, the last vestiges of his heroic posture vanishing completely. He looked small. He looked old. He looked terrified.

 

"Izuku," Toshinori whispered, taking a step forward. "Izuku, please, listen to me."

 

"You... you're All Might?" Izuku’s voice was barely audible over the wind. Tears spilled over his cheeks, his mind fracturing. The man who had saved him in the tunnel... the god-like figure he had worshipped since he could walk... the Number One Hero in the world... was his sickly, dorky older brother who slept on their couch during the holidays?

 

"Yes," Toshinori said, his voice breaking. He walked over and fell to his knees directly in front of Izuku. He didn't care about the gravel digging into his thin skin. He reached out, his trembling hands gently grabbing Izuku’s shoulders. "Izuku, I'm so sorry. I am so, so sorry."

 

"Why?" Izuku cried, staring at his brother's hollow face, finally seeing the crushing weight of the world in those familiar blue eyes. "Why didn't you tell me? Why didn't you tell Mom? You lied to us! My whole life, you lied!"

 

"I had to!" Toshinori pleaded, his grip tightening slightly, pulling Izuku closer. "You have to understand, Izu. The things I do... the enemies I have... if they knew about you. If they knew about Mom... they would kill you. They would tear you apart to get to me."

 

Toshinori suddenly let go of one shoulder and reached for the hem of his oversized white t-shirt. With a grimace, he pulled it up.

 

Izuku gasped, throwing his hands over his mouth to muffle a scream.

 

Covering the entire left side of Toshinori’s torso was a horrific, gnarled mass of scar tissue. It looked like a crater in his flesh, the skin purple and red, spider-webbing outward from a central, devastating impact point. It looked fatal. It looked like a corpse's wound.

 

"I got this five years ago," Toshinori said, his voice deadly serious, devoid of any warmth. "An enemy attacked me. A true monster. My respiratory system was nearly destroyed. I lost my whole stomach. All the surgeries have worn me down, and it can't be fixed. Right now, I can only do hero work for about three hours a day. The rest of the time... I look like this."

 

Izuku stared at the grotesque scar, a wave of nausea hitting him. Five years ago. That was when Toshinori had suddenly stopped visiting for six months. He had told Inko he was sent on a business trip to America. He had been lying in a hospital bed, dying.

 

"You were dying," Izuku whispered, reaching out with a trembling hand, stopping just inches from the ruined flesh. "You were dying alone, and we didn't even know."

 

"I wasn't alone, I had friends looking out for me," Toshinori said softly, pulling the shirt back down. He grabbed Izuku’s hand, clasping it between his two massive, bony ones. "But I couldn't drag you and Mom into this world. I am the Symbol of Peace, Izuku. The Symbol cannot have vulnerabilities. It cannot have a family. So I kept you in the dark. To protect you."

 

Izuku looked at his brother’s hands. They were cold, scarred, and trembling slightly. The hands of the greatest hero in history, holding onto him like a lifeline.

 

"I'm sorry I blew your secret," Izuku whispered, tears dripping onto their joined hands. "I'm sorry I was so reckless."

 

"You idiot," Toshinori breathed, pulling Izuku into a tight, desperate embrace. He buried his gaunt face into his little brother's messy green curls. "When I realized it was you holding onto my leg... my heart stopped. I thought you were going to fall. Don't you ever, ever do something so stupid again."

 

Izuku hugged his brother back, burying his face in the oversized t-shirt that smelled faintly of blood, sweat, and the grilled mackerel from this morning. For a moment, the world faded away. There was no All Might. There was no Number One Hero. There were just two brothers on a rooftop.

 

But then, reality clawed its way back into Izuku’s mind.

 

He remembered his question. He remembered Bakugo’s words. He remembered the sludge villain violating his lungs, telling him he was powerless.

 

Izuku slowly pulled back, wiping his nose with the back of his sleeve. He looked up at Toshinori, his green eyes burning with a desperate, agonizing vulnerability.

 

"Toshi-nii," Izuku croaked.

 

Toshinori swallowed hard, seeing the terrifying intensity in the boy's gaze. "Yes, Izu?"

 

"Before you transformed back..." Izuku took a shuddering breath. "I asked you a question. And... and I need the truth. Not a lie to protect me. I need the absolute truth from the Number One Hero."

 

Toshinori’s blood ran ice cold. He knew exactly what the boy was going to ask. And he knew, with horrific certainty, what his answer had to be.

 

"Can a Quirkless nobody like me," Izuku whispered, his lip trembling, "become a hero like you?"

 

The silence on the rooftop was suffocating.

 

Toshinori looked at his baby brother. He saw the burn marks on his uniform collar. He saw the waterlogged, ruined notebook sticking out of the yellow backpack. He remembered his own youth, the brutal beatings, the mocking laughter, the sheer, paralyzing helplessness of facing villains with nothing but bare fists and a dream.

 

He loved Izuku more than life itself. He would rip out his own heart and give it to the boy if it would make him happy.

 

But he knew the reality of this world. He knew the monsters that lurked in the shadows. He had just shown Izuku the scar that had nearly killed him—and he had the greatest power in the world. What would that villain have done to a Quirkless child?

 

If I say yes, Toshinori thought, a profound agony tearing through his soul, he will run out there, and he will die. I will bury my brother before he turns fifteen.

 

Toshinori closed his eyes, a single tear escaping his lashes and tracing a path down his hollow cheek. He hardened his heart, preparing to break the only thing he had sworn to protect.

 

He opened his blue eyes, looking straight into Izuku’s desperate green ones.

 

"No, Izuku," Toshinori said, his voice cracking, devoid of the Symbol of Peace's booming confidence, filled only with a brother's terrifying honesty. "Without a Quirk... you cannot be a hero."

 

Izuku stopped breathing.

 

The light in his bright, emerald eyes shattered, dissolving into a hollow, empty void. The tears stopped falling. He simply went numb.

 

The god he worshipped had just descended from the heavens, wearing the face of the brother he loved, to tell him his dream was dead.

 

Toshinori reached out, his heart fracturing at the look of absolute devastation on Izuku’s face. "Izu, please, you have to understand. It's too dangerous. The villains I face... they would tear you apart. I can't lose you. Mom can't lose you. You can be a police officer, or a doctor. You can save people without fighting. But pro hero work... it requires power you simply don't have."

 

Izuku slowly stood up. His movements were mechanical, stiff. He didn't look at Toshinori. He looked at the gravel beneath his feet.

 

"I see," Izuku whispered, his voice completely dead.

 

"Izuku—"

 

"I should get home," Izuku interrupted, his tone chillingly polite. He turned toward the rooftop access door. "Mom will be worried. And... and you need to rest, Toshi-nii. You've reached your limit."

 

Toshinori scrambled to his feet, reaching out, but Izuku had already opened the heavy metal door.

 

"Izuku, wait! Let me walk you home!"

 

"I'm fine," Izuku said, finally looking back. The smile on his face was identical to the one he had worn in the entryway that morning—practiced, fake, and utterly heartbreaking. "I'm sorry I bothered you at work, All Might. I'll keep your secret."

 

The door slammed shut, the heavy metallic clang echoing across the empty roof.

 

Toshinori Yagi stood alone in the wind. He stared at the closed door, the phantom sensation of his brother’s tears still wet on his scarred hands.

 

He had protected his little brother's life. He was sure of it.

 

So why did it feel like he had just committed murder?

 

Toshinori sank to his knees, burying his face in his hands, and for the first time in five years, the Symbol of Peace wept.

 

The stairwell was dark, smelling faintly of mildew and old cigarettes, but to Toshinori Yagi, it felt like descending into a tomb.

 

His boots dragged heavily against the concrete steps. Each footfall echoed in the oppressive silence, a rhythmic mocking of his own failure. He pressed his massive, bony hand against his chest, right over the grotesque scar that served as a constant reminder of his mortality. The physical pain, the sharp stabbing sensation of his missing organs and overworked respiratory system, was nothing. It was an ambient hum compared to the agonizing, tearing sensation in his heart.

 

I broke him, Toshinori thought, his vision blurring as tears stung his sunken blue eyes. I took the brightest, most beautiful part of that boy, and I crushed it with my bare hands.

 

He remembered the look in Izuku’s eyes just moments ago. The sheer, unfathomable devastation. It was a look Toshinori had seen on the faces of victims whose families had been crushed under rubble, or civilians who realized the heroes had arrived too late. It was the look of a soul losing its anchor to the world.

 

Toshinori leaned heavily against the cold metal railing, a wracking cough tearing through his frail body. He brought a handkerchief to his mouth, tasting the familiar, metallic tang of copper.

 

He was the Symbol of Peace. He had carried bridges on his back. He had stood against the darkest evils of the underworld and laughed in their faces. Millions of people looked at him and felt safe.

 

But as an older brother, he was an abject, miserable failure.

 

What else could I do? he pleaded with the empty stairwell, his grip on the railing tightening until his knuckles turned white. If I told him yes, if I encouraged him... he would die. He is Quirkless. He is small, and fragile, and he has a heart that is too big for his chest. The villains in this world don't care about a pure heart. They would tear him to pieces.

 

He thought of Inko. He thought of his mother’s gentle smile, the way she worried over both of them. If Izuku went out into the field as a hero and came back in a body bag, it would kill her. The Midoriya family would be destroyed, all because Toshinori couldn't protect his baby brother from his own impossible dreams.

 

"It was for his own good," Toshinori whispered aloud, the raspy sound of his true voice echoing pathetically in the stairwell. "It was to keep him alive."

 

He reached into the deep cargo pocket of his pants, searching for the plastic soda bottles containing the sludge villain. He needed to hand the criminal over to the police, file his report as All Might, and then go home. He needed to go back to the apartment, buy Izuku his favorite katsudon, and somehow, miraculously, piece his little brother’s broken heart back together.

 

His fingers brushed against the fabric of his pocket. Nothing.

 

Toshinori froze. His breath hitched. He patted his other pocket. Empty.

 

Panic, icy and absolute, flooded his veins. He looked down at his hands, trying to retrace his steps. He had grabbed Izuku to keep him from falling. The G-force. The struggle in the air.

 

No. No, no, no...

 

Before the realization could fully solidify in his mind, a sound shattered the quiet afternoon.

 

BOOM.

 

The explosion was massive, rattling the very foundations of the building. The sound of shattering glass and screaming sirens instantly followed.

 

Toshinori scrambled down the remaining flights of stairs, his heart hammering against his ribs in a terrifying, erratic rhythm. He burst through the ground-floor exit and stumbled into the street.

 

A thick plume of black, acrid smoke was rising into the sky a few blocks away. The orange glow of an uncontrolled fire reflected against the glass windows of the surrounding skyscrapers.

 

I dropped him, Toshinori realized, absolute horror seizing his throat. When I caught Izuku... the bottles fell.

 

He forced his aching, emaciated legs into a run. Every step was agony, his lungs burning as if he were inhaling shattered glass. But he didn't care. The Symbol of Peace had made a mistake. A catastrophic, amateur mistake. And now, innocent people were paying the price.

 

 

 

Izuku Midoriya didn't know where he was walking.

 

His red sneakers carried him through the bustling streets of Musutafu on pure, thoughtless autopilot. The vibrant city around him—the flashing neon signs, the chattering crowds, the distant rumble of the train cars—was muffled, as if he were submerged underwater.

 

He clutched the straps of his yellow backpack so tightly his fingers ached. Inside the bag sat the ruined, waterlogged Hero Analysis for the Future, No. 13. It was heavy against his back. A literal burden.

 

No, Izuku. Without a Quirk... you cannot be a hero.

 

The words looped in his mind, a relentless, torturous mantra. It wasn't just the words; it was the voice that had spoken them.

 

Toshinori. Toshi-nii.

 

The man who had taught him how to ride a bicycle. The man who had sat by his bed and read him stories when he had a fever. The man who worked himself to the bone, who coughed up blood and hid his pain just to buy Izuku a notebook and a crepe.

 

His brother was All Might.

 

The revelation was too massive for Izuku's fourteen-year-old brain to process. His idol, the untouchable god of heroism, had been sleeping on their lumpy living room couch. All those times Izuku had excitedly shown Toshi-nii a video of All Might’s latest rescue... Toshinori had just smiled and nodded, carrying the weight of a secret that was slowly killing him.

 

He was dying, Izuku thought, a fresh wave of tears blurring his vision. Five years ago. That giant scar. He was dying, and he didn't tell us. He didn't want to worry us. He's suffering every single day.

 

And what had Izuku done? He had been a selfish, reckless, Quirkless burden. He had clung to All Might's leg, forcing his brother to overexert himself, forcing him to reveal his darkest secret, all for a pathetic validation Izuku was never going to get.

 

Bakugo was right, Izuku thought numbly, his gaze dropping to the pavement. I'm a Deku. I'm useless. I just make things harder for everyone. Toshi-nii is right. I can't be a hero. I'm just a liability.

 

He remembered Bakugo’s cruel smirk.

 

Take a swan dive off the roof of the building!

 

Izuku stopped walking. He looked up, his dead green eyes tracing the sleek, towering height of a nearby office building. The roof seemed so high up. So peaceful.

 

If he was gone... Toshi-nii wouldn't have to worry about him anymore. His brother could focus on his health, on his hero work. He wouldn't have to spend his hard-earned money on a Quirkless failure.

 

A loud explosion snapped Izuku out of his dark spiral.

 

He blinked, the morbid trance breaking. The smell of smoke drifted past his nose. A crowd was gathering at the end of the street, murmuring nervously and pointing down a commercial alleyway.

 

A villain attack? Izuku’s mind, trained by years of observation, immediately kicked into gear. Which heroes are on the scene?

 

He shook his head violently. No. Stop it. It doesn't matter anymore. You're not a hero. You're never going to be a hero. Walk away.

 

But his feet betrayed him. The ingrained habit was too strong. Before he realized it, Izuku was pushing his way to the front of the crowd, stopping just behind the police barricade tape.

 

The sight before him made his blood freeze in his veins.

 

The alleyway was a warzone. Fires raged on both sides of the street, licking up the walls of the shops and shattering windows. The heat was blistering, rolling over the crowd in suffocating waves.

 

And in the center of the destruction, laughing maniacally, was the Sludge Villain.

 

No, Izuku’s breath caught in his throat. His eyes widened in absolute horror. That's... that's the villain from the underpass! But... All Might captured him! I saw the bottles!

 

A sickening memory flashed in his mind. He remembered lunging at All Might's leg. He remembered the jolt in the air.

 

If I hadn't grabbed his leg... the bottles wouldn't have fallen.

 

Izuku clamped his hands over his mouth, suppressing a scream of pure agony. This is my fault. Everything happening right now is my fault!

 

"Why aren't the heroes doing anything?!" a man in the crowd yelled.

 

Izuku looked around frantically. Several pro heroes were on the scene. Death Arms, Kamui Woods, Mt. Lady, and Backdraft.

 

"I can't get close!" Death Arms grunted, shielding his face from a massive explosion that rocked the alley. "The heat is too intense!"

 

"I need at least a two-lane road for my Quirk!" Mt. Lady complained, standing uselessly at the intersection. "I'm too big for this alley!"

 

"My wood will catch fire if I get any closer!" Kamui Woods yelled, helping civilians evacuate a nearby store.

 

"We just have to wait for someone with a suitable Quirk!" another hero shouted. "Hold the line! Keep the fire from spreading!"

 

Izuku stared at them, uncomprehending. Wait? What are they talking about? Why are they waiting?

 

The Sludge Villain roared, whipping its muddy tendrils around, smashing a streetlamp. "I hit the jackpot with this kid! What a Quirk!"

 

Izuku looked closer, squinting through the thick smoke. The villain had taken a hostage. It was using the hostage's Quirk to create the explosions and keep the heroes at bay.

 

Through a gap in the swirling, foul-smelling sludge, Izuku saw a patch of spiky, ash-blonde hair. He saw a hand, desperately clawing at the muck, setting off wild, uncontrolled explosions in a panic.

 

And then, he saw a face.

 

Katsuki Bakugo’s eyes were wide. The cocky, arrogant superiority was entirely gone. His face was pale, his eyes bloodshot, his mouth open in a desperate, silent scream for oxygen.

 

Tears streamed down Bakugo’s face. He was suffocating. He was terrified. He was dying.

 

Izuku’s heart completely stopped.

 

 

 

Standing in the back of the crowd, hidden behind a telephone pole, Toshinori Yagi gripped the wood so hard his bloody fingernails dug into the bark.

 

He was trembling, his breathing ragged and shallow. He stared at the sludge villain, then at the captive boy, and finally at the pro heroes who were standing back and waiting.

 

Pathetic, Toshinori thought, a vicious, self-loathing venom flooding his mind. They are pathetic. But you... you are the most pathetic of all, Toshinori.

 

He reached deep inside himself, searching for the golden, roaring inferno of One For All. He begged his body to transform. He needed the muscle. He needed the power. He needed to be All Might.

 

But there was nothing. The well was dry. His body screamed in agony, the scar on his chest burning as if it were packed with dry ice. He had used up every single second of his limit. If he tried to force the transformation now, his body would literally tear itself apart.

 

I caused this, Toshinori thought, tears of ultimate shame tracking through the dirt on his gaunt face. I dropped the bottles. I lectured a child on what it takes to be a hero, and now I am standing here, hiding in the shadows, letting a middle schooler die because I am too weak to save him.

 

He was a hypocrite. He was a fraud.

 

He watched the sludge villain tighten its grip on the blonde boy. The boy's explosions were growing weaker. He was running out of air.

 

I'm sorry, Toshinori wept silently, unable to look away from his own failure. I'm so sorry.

 

And then, something shattered the paralysis.

 

A blur of dark black fabric and a bright yellow backpack shot out from the front of the crowd.

 

The pro heroes gasped. "Hey! Stop! Get back here, you idiot!" Death Arms roared, reaching out, but his fingers just brushed the boy's collar.

 

Toshinori’s blue eyes blew wide open, the breath violently expelled from his lungs.

 

Sprinting into the inferno, his red sneakers pounding against the burning asphalt, was Izuku Midoriya.

 

IZUKU! Toshinori’s mind screamed, panic seizing him with a force far more terrifying than any villain he had ever faced. NO! WHAT ARE YOU DOING?! YOU'LL DIE!

 

To Izuku, the world had gone entirely silent.

 

He didn't hear the heroes screaming at him. He didn't hear the roar of the fire or the manic laughter of the villain.

 

He only saw Kacchan’s eyes. The eyes of his childhood tormentor, pleading for help.

 

Why am I running? Izuku’s mind raced, completely disconnected from his body's actions. What am I doing?! I don't have a plan! I don't have a Quirk! I'm going to die!

 

"You're back!" the Sludge Villain roared, recognizing the boy from the underpass. "Come to join your friend?!"

 

The villain raised a massive, spiked tendril of sludge, bringing it down like a guillotine toward Izuku.

 

Izuku’s encyclopedic knowledge, honed by years of obsessive note-taking, hijacked his panic. Page 25. Combat tactics. Obstruct the enemy's vision!

 

Without breaking stride, Izuku ripped his yellow backpack off his shoulders. With a fierce cry, he swung it by the strap, hurling it straight at the villain's face.

 

The bag flew true. The zipper burst open mid-air, sending textbooks, pencil cases, and a heavy, metal-edged pencil box flying directly into the sludge villain's giant, bulging eyeball.

 

"GAAAH!" The villain shrieked, the tendril missing Izuku by inches and smashing into the pavement. The sludge around Bakugo loosened for a fraction of a second.

 

Izuku didn't hesitate. He dove straight into the muck, his bare hands clawing desperately at the foul-smelling sludge. It burned his skin, but he didn't care. He grabbed the sludge around Bakugo’s mouth and ripped it away.

 

Bakugo gasped, inhaling a massive, shuddering breath of air. He coughed violently, his red eyes locking onto the freckled, tear-streaked face of the boy he had told to jump off a roof just hours ago.

 

"Deku?!" Bakugo choked out, stunned disbelief overriding his terror. "What the hell are you doing here?!"

 

Tears were streaming down Izuku’s face. He was terrified. He was shaking so hard his teeth rattled. But despite the fear, despite the absolute certainty of his own impending death, a furious, blinding smile broke across his face.

 

"Kacchan!" Izuku screamed, his fingers digging deeper into the sludge. "I couldn't just stand there and watch you die! You looked like you were asking for help!"

 

In the crowd, Toshinori Yagi stopped breathing.

 

The words struck him like a physical blow, vibrating straight to the very core of his soul.

 

He watched his Quirkless, fragile, fourteen-year-old baby brother clawing at a monster that pro heroes were afraid to approach. He watched Izuku weeping with terror, yet smiling to reassure the victim.

 

He is afraid, Toshinori realized, a profound, earth-shattering awe washing over him. He is utterly terrified. He knows he has no power. He knows he has no chance of winning. And yet... his body moved before he even had time to think.

 

It was the one undeniable truth of the universe. The one fundamental law that governed every great hero in history.

 

There are stories about every great hero, Toshinori thought, stepping out from behind the telephone pole, the fires reflecting in his suddenly fierce blue eyes. How they became great. Most of their stories have one thing in common. Their bodies moved before they had a chance to think.

 

"I'M GONNA KILL YOU, BRAT!" the Sludge Villain roared, recovering from the blow to its eye. It raised two massive tendrils, rearing back to crush Izuku into a bloody smear on the pavement.

 

"Izuku, get out of there!" Death Arms yelled, finally charging forward, but he was too far away. He wasn't going to make it.

 

Izuku squeezed his eyes shut. He threw his arms over Bakugo, shielding the blonde boy with his own body.

 

I'm sorry, Mom, Izuku thought. I'm sorry, Toshi-nii. I couldn't be a hero. But at least I tried.

 

He waited for the crushing impact. He waited for the end.

 

But the impact never came.

 

Instead, a hand—massive, calloused, and radiating a heat hotter than the surrounding fires—grabbed Izuku by the back of his uniform collar and violently yanked him backward, pulling him and Bakugo out of the sludge.

 

Izuku tumbled across the asphalt, scraping his knees and elbows. He gasped, opening his eyes.

 

Standing between him and the monster was a mountain of muscle. The white t-shirt was gone, replaced by a massive, muscular back, steam rising off his golden skin. The two prominent bangs stood tall, defying gravity.

 

"Toshi..." Izuku whispered, the word barely escaping his lips.

 

All Might stood tall, coughing up a terrifying amount of blood, but his trademark smile was carved onto his face with absolute, unyielding fury.

 

"I really am pathetic," All Might said, his booming voice echoing in the alley, tinged with a deep, personal shame.

 

"All Might?!" the villain screeched, shrinking back.

 

"I TOLD YOU WHAT IT TAKES TO BE A HERO," All Might roared, looking back over his shoulder, his blue eyes locking onto Izuku. The look was not one of a hero to a civilian. It was the look of a fiercely proud, utterly terrified older brother. "AND YET, I WAS NOT LIVING UP TO MY OWN IDEALS!"

 

All Might turned back to the villain. He planted his boots into the asphalt, the ground spider-webbing beneath his weight. He crossed his arms over his chest, gripping his own forearms, pulling every single ounce of power left in his shattered body, drawing on years off his own life to force the Quirk to obey.

 

"PROS MUST ALWAYS PUT THEIR LIVES ON THE LINE!"

 

All Might threw his arms outward, breaking his own blood vessels, and brought his right fist back. The air around him distorted, a vacuum forming as the sheer kinetic energy gathered in his knuckles.

 

"DETROIT..."

 

The villain lunged, a desperate, final strike.

 

"SMASH!"

 

All Might threw the punch.

 

He didn't hit the villain. He hit the air.

 

The resulting shockwave was not a gust of wind. It was a localized natural disaster. A tornado of absolute, unstoppable force erupted from All Might’s fist. It tore through the alley, ripping the fire out of the air, extinguishing the flames instantly. The sludge villain was atomized, the mud blasted apart with such violence that it rained down across three city blocks.

 

The force of the wind hit the crowd, blowing pro heroes and civilians off their feet. Izuku grabbed onto a street sign, his body flying horizontal in the air, his eyes wide in absolute shock.

 

And then, silence fell over the alley.

 

All Might stood breathing heavily, his fist still extended. He looked up at the sky.

 

The sheer air pressure from the Detroit Smash had punched a hole straight through the atmosphere. The clouds above Musutafu swirled, gathering rapidly. A second later, a cold drop of water hit Izuku’s cheek. Then another.

 

"Rain?" Death Arms muttered, staring up in awe. "He changed the weather... with a single punch?"

 

The crowd erupted into deafening cheers. "All Might! All Might! All Might!"

 

All Might stood perfectly still, his massive chest heaving. He slowly turned his head, his eyes finding Izuku sitting on the wet pavement. He gave a small, exhausted nod, before turning away to address the press.

 

Izuku sat there in the rain, trembling. He had been saved again. His brother had pushed past his limits, risking his life, all because Izuku was too weak to do anything himself.

 

The guilt was crushing.

 

 

 

The aftermath was a blur.

 

The pro heroes immediately descended on Izuku. Death Arms and Kamui Woods dragged him away from the scene, practically pinning him against a police cruiser.

 

"Are you out of your damn mind?!" Death Arms yelled, his face red with anger. "There was absolutely no reason for you to put yourself in danger! You got in our way! If All Might hadn't shown up, you'd both be dead!"

 

"You have no Quirk, kid," Kamui Woods added, his tone softer but just as reprimanding. "That was incredibly foolish. Leave the hero work to the professionals. You're lucky to be alive."

 

Izuku kept his head bowed, staring at his muddy, torn sneakers. "I'm sorry," he whispered. "I know. I'm sorry."

 

Across the street, it was a completely different story. The heroes were crowding around Katsuki Bakugo, praising him.

 

"That Quirk of yours is incredible!" Mt. Lady beamed.

"Your endurance is amazing to hold out that long!"

"When you graduate, come to my agency! You have a bright future as a hero!"

 

Izuku watched them, a hollow, bitter feeling settling in his chest. They're right. Kacchan has a powerful Quirk. He's strong. I'm just a Quirkless nobody who gets in the way.

 

After taking his statement, the police finally let him go. Izuku retrieved his ruined yellow backpack from the debris, bowed deeply to the officers, and began the long walk home.

 

The sun was setting, casting a bloody, orange glow over the city. The evening air was cold, especially in his wet clothes, but Izuku didn't feel it. He felt numb.

 

"DEKU!"

 

Izuku stopped, his shoulders tensing. He turned around.

 

Katsuki Bakugo was marching down the street toward him, his fists clenched, his breathing heavy. He looked furious, but there was a strange, frantic edge to his anger.

 

"Kacchan?" Izuku murmured.

 

Bakugo stopped a few feet away, panting. He glared at Izuku, his red eyes burning with a mix of rage, humiliation, and something that looked dangerously close to gratitude.

 

"Listen to me, you Quirkless loser!" Bakugo yelled, his voice echoing off the brick walls of the residential street. "I didn't ask for your help! You didn't save me! Got it?! I was fine! I had it under control! I don't owe you a damn thing! Don't you dare think you can look down on me!"

 

Bakugo spun on his heel, aggressively marching away, leaving Izuku standing on the sidewalk in stunned silence.

 

Izuku let out a long, exhausted sigh. "Tough as ever, Kacchan," he muttered.

 

He turned to continue his walk home, dreading the moment he would have to walk through the front door. He didn't know if Toshinori would be there. He didn't know how he could ever look his brother in the eye again after what he had done. He had forced Toshi-nii to use his Quirk when he was already dying.

 

"I AM HERE!"

 

Izuku jumped, nearly dropping his bag, as All Might suddenly burst from a nearby alleyway, sliding across the pavement and striking a dramatic pose in front of him.

 

"A-All Might?!" Izuku gasped. "I mean... T-Toshi-nii?! What are you doing here?! How did you get away from the reporters?!"

 

"A hero must always be quick on his feet! I simply jumped away— BLLLGH!"

 

Toshinori didn't even get to finish his sentence before he deflated in a massive cloud of steam, violently coughing up a frightening amount of blood. He collapsed against a nearby telephone pole, sliding down until he was sitting on the curb, his skeletal chest heaving as he gasped for air.

 

"Toshi-nii!" Izuku cried in panic, dropping his bag and rushing over. He dropped to his knees, frantically patting his pockets for a tissue. "Are you okay?! Why did you push yourself?! You said you were out of time!"

 

Toshinori raised a trembling, bony hand, waving Izuku off. He wiped the blood from his mouth with the back of his sleeve. He looked exhausted, paler than death, but his blue eyes were sharp and focused entirely on his little brother.

 

"Izuku," Toshinori rasped, his voice incredibly quiet. "I... I came to find you."

 

Izuku’s hands fell to his lap. He looked down at the concrete. The guilt surged back, suffocating him.

 

"I'm sorry," Izuku whispered, tears instantly filling his eyes again. "I'm so sorry, big brother. I ruined everything. I dropped the bottles. I made you push past your limit. You're hurt because of me. And... and I know what you're going to say. The heroes already yelled at me. I was reckless. I got in the way. I'm just a Deku."

 

Toshinori stared at the boy. He listened to his little brother degrade himself, parrot the cruel words of a society that didn't understand what true heroism was.

 

Toshinori shifted, groaning as his scarred chest protested, and moved from the curb to sit directly in front of Izuku on the sidewalk. He reached out and placed his hands on Izuku’s shoulders.

 

"Izuku. Look at me."

 

Izuku slowly raised his head. His green eyes were swimming with tears.

 

"The pro heroes were wrong," Toshinori said firmly, his voice steady. "I was wrong. I came here to thank you, and to apologize."

 

Izuku blinked, confused. "Apologize? But I—"

 

"If you hadn't been there," Toshinori interrupted, his grip tightening gently on Izuku’s shoulders. "If you hadn't run into that fire... I would have stood in the crowd, hiding behind a telephone pole, and I would have let that boy die. I was making excuses. I was terrified of my own weakness."

 

Toshinori leaned forward, his blue eyes intense, piercing straight into Izuku’s soul.

 

"You, a Quirkless, defenseless kid, had more bravery in your little finger than every pro hero in that alley combined. You moved when no one else would. You inspired me to act. You saved my life, Izuku, and you saved my honor as a hero."

 

Izuku’s breath hitched. The tears spilled over, tracking through the dirt and soot on his face. He shook his head in denial. "No... no, I didn't do anything... I couldn't save him..."

 

"There are stories about every great hero," Toshinori said, his voice rising, carrying a profound, magical weight in the quiet evening air. "Most of their stories have one thing in common. Their bodies moved before they had a chance to think."

 

Izuku gasped. His hands flew to his chest, right over his heart. That was exactly what had happened. He hadn't thought. He had just run.

 

Toshinori smiled. It wasn't the boisterous, blinding smile of All Might. It was the gentle, deeply proud, impossibly fond smile of Toshi-nii.

 

"That was true for you today, wasn't it?" Toshinori asked softly.

 

Izuku broke. He collapsed forward, burying his face in his hands, and sobbed. The agonizing weight of a decade of bullying, of hopelessness, of being told he was worthless, finally cracked. He wailed, his small shoulders shaking violently, the sound echoing down the empty street.

 

Toshinori pulled his little brother into his chest, wrapping his long, thin arms securely around him. He rested his chin on top of Izuku’s messy green curls, letting the boy cry out all the pain he had kept bottled up for years.

 

"I am so sorry I told you that you couldn't do it," Toshinori whispered into Izuku’s hair, his own tears falling silently. "I was scared. I am still scared. I'm your older brother, Izu. My job is to protect you. And the thought of you getting hurt... it terrifies me more than anything in this world."

 

Toshinori pulled back slightly, forcing Izuku to look up at him.

 

"But I was wrong to project my fear onto you. I forgot what it meant to be a hero, and you reminded me. So, I need to tell you the truth. The absolute truth."

 

Toshinori took a deep breath.

 

"You can become a hero."

 

Izuku’s eyes widened. The world seemed to stop spinning. The wind died down. The setting sun cast a golden halo around Toshinori’s sunken face.

 

You can become a hero.

 

It was the only thing Izuku had ever wanted to hear. And hearing it from the greatest hero in the world, from his beloved older brother, was a catharsis so powerful it nearly knocked him unconscious.

 

"But," Toshinori continued, his expression turning deadly serious. "You cannot do it without power. The villains out there will not hesitate to kill you, and I cannot allow my baby brother to walk into a slaughterhouse unarmed."

 

Izuku wiped his eyes, confused. "But... you just said... I'm Quirkless. I can't grow a Quirk."

 

"No, you can't," Toshinori said. He slowly extended his right hand, holding it palm up between them. "But what if I told you... a Quirk could be given to you?"

 

Izuku stared at Toshinori's hand. "Given? That's impossible. Quirks are genetic anomalies. They're biological functions. They can't just be transferred like a—"

 

"I am living proof that they can," Toshinori interrupted gently.

 

Izuku stopped muttering. He stared at his brother.

 

Toshinori looked down at his own hand, a profound reverence in his eyes. "The media debates constantly about the true nature of my Quirk. Super strength? Durability? A physical enhancement? I dodge the questions with jokes and catchphrases because the truth is far more dangerous."

 

Toshinori looked back up at Izuku.

 

"My Quirk was given to me. I inherited it, like a sacred torch passed down from one generation to the next. The true name of my power... is One For All."

 

"One... For All?" Izuku repeated, testing the words on his tongue.

 

"Yes," Toshinori nodded. "One person cultivates the power, and passes it on to another. The next person cultivates it further, and passes it on. It is the crystalline crystallization of power, born from the voices of those who cry out for help. A power meant to save people."

 

Izuku was trembling, his brilliant mind racing to comprehend the sheer scale of what he was being told. "But... why? Why give it to someone else? And why you?"

 

Toshinori smiled, a bittersweet, nostalgic expression. "Because, Izuku... before I received this power, forty years ago... I was exactly like you."

 

Izuku gasped. "What?"

 

"I was Quirkless," Toshinori admitted, his voice quiet. "I was a scrawny, helpless kid with a dream that was too big for my body. I wanted to be a Symbol. A pillar that society could lean on so they wouldn't have to be afraid. Everyone laughed at me. Except for one person. My master. She saw something in me, just like I saw something in you today."

 

Toshinori moved his hand, gently pressing his palm against Izuku’s chest, right over his heart.

 

"I have been looking for a successor for a long time, Izuku. My body is failing. My time as the Symbol of Peace is coming to an end. I thought I had to look among the brightest, strongest students with powerful Quirks. But I was wrong."

 

Toshinori’s blue eyes blazed with a sudden, overwhelming intensity. It was the fire of All Might, burning brightly within the frail vessel of Toshinori Yagi.

 

"I don't want a successor who was born with power and doesn't understand the pain of the weak. I want someone who knows what it means to be helpless, and chooses to stand up anyway. I want someone with the heart of a true hero."

 

Toshinori leaned in, his voice dropping to an emotional, trembling whisper.

 

"I want you, Izuku. I want my brother to inherit my legacy."

 

Izuku couldn't breathe. The weight of the offer was astronomical. The Number One Hero, the Symbol of Peace, his older brother, was offering him the key to his dreams. He was offering him his own, personal power.

 

"Me?" Izuku choked out. "But... Toshi-nii, I'm just... I'm a Deku. I'm clumsy, and I cry all the time, and I..."

 

"You are Izuku Midoriya," Toshinori said firmly, his thumb gently wiping away a fresh tear from Izuku’s cheek. "You are my brother. And today, you were the greatest hero I have ever seen. So, I will ask you one last time, and I want you to think carefully before you answer. This power is a heavy burden. It will put a target on your back. It will break your bones and test your soul. But if you take it... you will never be powerless again."

 

Toshinori held out his hand again.

 

"Will you accept my power, Izuku?"

 

Izuku looked at the scarred, calloused hand extended toward him. He thought of the years of bullying. He thought of Bakugo’s explosions. He thought of his mother’s worried tears.

 

He thought of Toshinori, bleeding and coughing, carrying the weight of the entire world on his shoulders, entirely alone.

 

I won't let him carry it alone anymore, Izuku thought, a fierce, unbreakable resolve igniting deep within his soul. I will be strong. I will stand by his side. I will protect my brother, and I will protect everyone else.

 

Izuku reached out. His small, trembling hand met Toshinori’s massive, scarred one. He gripped it with every ounce of strength he possessed.

 

He looked his brother dead in the eye, the tears of sorrow replaced by a burning, brilliant determination.

 

"Yes," Izuku said, his voice steady for the first time all day. "I accept, Toshi-nii. I'll do it. I will make you proud."

 

Toshinori’s face broke into a massive, blinding smile, tears streaming freely down his gaunt cheeks. He pulled Izuku into another fierce hug, burying his face in the boy's shoulder.

 

"I know you will, Izu," Toshinori laughed, the sound wet and emotional. "I already am."

 

The two brothers sat on the sidewalk as the streetlights flickered to life around them. The pact was made. The torch was ready to be passed.

 

"Now then," Toshinori suddenly groaned, pulling back and holding his stomach. "We should probably get home. Mom is going to kill us for being out this late. And... my ulcer is genuinely killing me."

 

Izuku wiped his eyes, a genuine, bright laugh escaping his lips. "I'll help you up, Toshi-nii. We can get katsudon on the way home."

 

Toshinori smiled, leaning on his little brother as they slowly stood up. "Katsudon sounds perfect. You're going to need the calories, kiddo."

 

Izuku paused, throwing his arm around his brother's waist to support him. "Why?"

 

Toshinori looked down at Izuku, a distinctly sadistic, trainer's gleam suddenly appearing in his blue eyes, completely replacing the weeping brother from a moment ago.

 

"Because, my boy," Toshinori said, his voice taking on a hint of All Might's booming cadence. "The U.A. Entrance Exams are in exactly ten months. Your body is a fragile twig. If I give you One For All right now, your limbs will violently explode and you will die instantly."

 

Izuku froze. The color rapidly drained from his face. "E-Explode?"

 

"Violently!" Toshinori confirmed with a cheerful thumbs-up. "So, starting tomorrow morning at 5:00 AM, we begin your training! I am going to push you to the absolute brink of death, Izuku! It will be a living hell! HA HA HA HA!"

 

Toshinori began to cough violently again, hunching over.

 

Izuku stared at his brother, terror rapidly replacing his heroic resolve. "Toshi-nii... you're scaring me."

 

"It's tough love, Izu!" Toshinori wheezed, patting Izuku on the back. "Now, let's go home. I need to figure out how to explain to Mom why you look like you wrestled a sewage pipe."

 

As they walked down the street, leaning on each other under the glow of the streetlights, Izuku felt a strange, terrifying, exhilarating warmth blooming in his chest. His dream wasn't dead. It had just begun.

 

And he wasn't doing it alone. He had the Number One Hero in his corner.

 

He had his brother.

 

The alarm clock on Izuku Midoriya’s desk did not gently beep. It screamed.

 

At exactly 4:30 in the morning, the harsh, electronic blare shattered the peaceful silence of his bedroom. Izuku’s hand shot out from beneath his All Might themed duvet, slapping blindly at the nightstand until he hit the snooze button.

 

The silence that followed was heavy, broken only by the sound of his own exhausted breathing and the distant rumble of a train somewhere in Musutafu. It was still pitch black outside. The rest of the city was asleep.

 

Izuku groaned, rolling onto his back. Every single muscle in his fourteen-year-old body was singing a chorus of agonizing, unfamiliar pain. His shoulders throbbed, his calves burned, and his lower back felt as though it had been beaten with a sack of doorknobs.

 

It had been exactly three days since he had accepted Toshinori’s offer. Three days since his older brother had promised to pass down the legendary Quirk, One For All.

 

Izuku forced his eyes open, staring at the ceiling. The exhaustion was overwhelming, pulling at him like gravity, begging him to go back to sleep. But then he remembered the look in his brother’s blue eyes—the fierce, unyielding belief that Izuku could be a hero.

 

With a sharp exhale, Izuku threw off the covers. He didn't have a Quirk to rely on yet. He only had his grit, and a ten-month ticking clock before the U.A. Entrance Exams.

 

He quietly dressed in his middle school gym uniform—a dark blue tracksuit with white stripes—and grabbed his worn-out red sneakers. Tiptoeing out of his room, he navigated the hallway with practiced precision, avoiding the creaky floorboard near the bathroom.

 

He didn't need to be stealthy for Toshinori, who was already awake, sitting on the lumpy living room sofa and tying the laces of his oversized combat boots.

 

Toshinori looked up as Izuku entered. The gaunt man was dressed in his usual baggy cargo pants and an absurdly large, white long-sleeved shirt that practically swallowed his skeletal frame. Dark bags hung under his piercing blue eyes, a testament to his own failing health, but he offered a warm, raspy chuckle at the sight of his little brother.

 

"Morning, Izu," Toshinori whispered, keeping his voice low so as not to wake Inko in the master bedroom. "You look like a zombie. If you’re too sore, we can do light stretching today."

 

"I’m fine, Toshi-nii!" Izuku whispered back, perhaps a little too loudly, before wincing as a sharp pain shot up his hamstring. He quickly forced a bright smile, puffing out his chest. "I’m perfectly fine! 100 percent! Ready to go!"

 

Toshinori raised an incredibly skeptical, thin blonde eyebrow. He slowly reached into a plastic grocery bag sitting on the coffee table and pulled out a meticulously wrapped bento box.

 

"I made this for your post-workout," Toshinori said, holding it out. "Steamed chicken breast, broccoli, brown rice, and three hard-boiled eggs. A perfectly calculated balance of macros. I also packed those little octopus wieners you like, just because."

 

Izuku took the box, his stomach giving a loud, embarrassing rumble. He felt a rush of affection. Even while planning a brutal training regimen, Toshinori couldn't stop being an overprotective older brother.

 

"Thanks, big brother," Izuku beamed, carefully placing the bento in his bag.

 

"Don't thank me yet, kiddo," Toshinori said, standing up, his joints popping audibly in the quiet apartment. A sadistic, terrifyingly serious glint flashed in his eyes. "Once we step out that door, I am no longer just 'Toshi-nii'. I am your instructor. And I am going to push you harder than you have ever been pushed in your life."

 

Izuku swallowed hard, nodding firmly. "Yes, sir."

 

They slipped out the front door, the cool, salty morning breeze hitting them instantly. The walk to their destination was quiet, the sky slowly shifting from pitch black to a deep, bruised purple.

 

Ten minutes later, they stood at the edge of the municipal Dagobah Beach Park.

 

Or, at least, it used to be a beach park.

 

Izuku stood at the top of the concrete stairs, his jaw dropping in sheer horror. The sand was completely invisible, buried beneath a literal mountain range of illegal dumping. Refrigerators, rusted washing machines, tires, shattered dressers, and broken electronics formed towering, precarious spires of garbage. The smell of rotting seaweed mixed with rust and stagnant water was eye-watering.

 

"What... what is this?" Izuku breathed. "I knew Dagobah Beach was bad, but... this is a disaster."

 

"Because of the ocean currents, anything dropped in the water tends to wash up here," Toshinori explained, standing beside him with his hands in his pockets. "And because people are fundamentally lazy, they take advantage of the mess to illegally dump their heavy appliances to avoid disposal fees. It’s a blemish on our local community."

 

Toshinori suddenly turned to Izuku, reaching into his cargo pocket and pulling out a massive, heavily stapled stack of papers. He dramatically slapped the packet into Izuku’s chest.

 

Izuku fumbled to catch it, looking at the bold, hand-drawn title page.

 

"THE AIM TO PASS: AMERICAN DREAM PLAN!"

 

"I stayed up all night finalizing the calculations!" Toshinori announced, his raspy voice filled with pride. "This is a ten-month, minute-by-minute schedule designed to take your frail, noodle-like body and forge it into a vessel capable of holding One For All! We are going to clean this entire beach, young Midoriya!"

 

Izuku stared at the endless ocean of trash, then down at his own scrawny arms, and finally back at the packet. He flipped to a random page.

 

06:15 AM - Haul four tires to the disposal truck while reciting the Pro Hero Code of Ethics.

07:00 AM - Eat precisely 45.6 grams of protein.

07:15 AM - Cry if necessary, then stretch.

 

"Toshi-nii..." Izuku’s voice trembled. "This... this is literally impossible. There are tons of garbage here! And a lot of it is heavier than I am! If I try to lift that refrigerator, my spine will snap!"

 

"That is exactly why you need to build muscle!" Toshinori countered cheerfully. Then, a massive cloud of steam erupted around him.

 

Izuku coughed, waving the steam away. When it cleared, All Might stood there, a towering colossus of muscle, striking a dynamic pose in the morning light.

 

"DO NOT FEAR, YOUNG MIDORIYA!" All Might boomed, his voice echoing over the trash heaps. "I WILL BE WITH YOU EVERY STEP OF THE WAY! NOW, GRAB THAT RUSTED MICROWAVE AND MARCH!"

 

Izuku gulped, terrified but undeniably inspired by the sheer presence of the Number One Hero. "Yes, All Might!"

 

Izuku scrambled down the concrete steps, his sneakers sinking into the small patch of exposed sand. He ran over to a discarded, waterlogged microwave sitting at the base of a trash pile. He bent his knees, gripped the sides, and pulled.

 

It didn't budge.

 

Izuku gritted his teeth, his face turning a brilliant shade of crimson as he pulled with all his meager strength. His arms shook violently, his sneakers sliding backward in the sand. With a pathetic, squeaking groan, the microwave shifted exactly two inches.

 

All Might stood at the top of the stairs, hands on his hips. "COME ON, YOUNG MIDORIYA! PUT YOUR BACK INTO IT! HEROES DO NOT LET KITCHEN APPLIANCES DEFEAT THEM!"

 

Izuku strained harder, managing to lift the microwave to his knees before his grip slipped. The heavy metal box slammed down, the jagged metal edge scraping violently against Izuku’s shin.

 

"AGH!" Izuku cried out, falling backward into the sand, clutching his bleeding leg. "Oww..."

 

"GET UP! PAIN IS JUST WEAKNESS LEAVING THE—!"

 

All Might froze. His heroic, unyielding smile dropped instantly. He stared at the trickle of blood running down Izuku’s shin.

 

POOF.

 

The steam returned, instantly deflating the Symbol of Peace into a panicking, skeletal older brother.

 

Toshinori practically threw himself down the concrete stairs, his long legs taking them three at a time. "Izu! Oh my god, are you okay?! Let me see!"

 

"I'm fine, Toshi-nii, it's just a scratch—"

 

"Don't move! You could get tetanus! There's rust everywhere!" Toshinori frantically reached into his deep pockets, producing an All Might-themed first aid kit, a bottle of antibacterial spray, and a packet of wet wipes.

 

Before Izuku could protest, Toshinori was on his knees in the sand, expertly cleaning the small cut with the precision of a surgeon. He sprayed it, wiped it, and slapped a brightly colored All Might band-aid over the tiny scratch.

 

"Does it hurt?" Toshinori asked, his blue eyes wide with absolute, maternal panic. "Do we need to go to the clinic? I have Recovery Girl on speed dial, I can call her right now—"

 

"Toshi-nii!" Izuku interrupted, his face burning with embarrassment. "It's literally a paper cut from a microwave! I'm fine! You said you were going to be a strict instructor!"

 

Toshinori blinked, looking at the tiny band-aid on Izuku’s leg, and then at the rusted microwave. He cleared his throat loudly, a blush creeping up his gaunt cheeks.

 

"Right. Yes. Ahem." Toshinori stood up, awkwardly brushing the sand off his baggy pants. He reached into his pocket and pulled out a red megaphone. He raised it to his mouth, even though he was standing exactly two feet away from Izuku.

 

"GET BACK TO WORK, MAGGOT!" Toshinori yelled through the megaphone, his voice cracking violently. "AND... AND MAKE SURE YOU LIFT WITH YOUR LEGS, NOT YOUR BACK! HYDRATE FREQUENTLY!"

 

Izuku couldn't help it. A small giggle escaped his lips, which quickly evolved into full-blown laughter. Toshinori looked entirely ridiculous, standing there looking like a sickly scarecrow holding a megaphone, desperately trying to play the tough guy while simultaneously hovering like a mother hen.

 

Toshinori lowered the megaphone, a small, fond smile breaking through his stern facade. "It's not funny, kiddo. If you don't take this seriously, you're going to get hurt."

 

"I am taking it seriously," Izuku promised, pulling himself up. He looked at the microwave, a new fire in his eyes. "I just need to figure out the leverage."

 

And so, the grueling ten-month hell began.

 

 

 

By the end of the first month, the dynamic between them had settled into a bizarre, heartwarming, and utterly exhausting routine.

 

Every morning at 5:00 AM, they were on the beach. Toshinori would sit on top of a rusted pickup truck in his muscle form, shouting encouragement and terrifying threats, holding Izuku strictly to the American Dream Plan. Izuku hauled tires, dragged dressers across the sand with ropes tied around his waist, and ran miles along the shoreline carrying cinder blocks.

 

But the moment the clock struck 7:00 AM, the muscle form would drop. Toshinori would deflate into a coughing, fretting mess. He would wrap Izuku in a towel, aggressively hand him electrolyte drinks, apply cold packs to his bruised shoulders, and force-feed him the meticulously packed bento boxes.

 

The physical toll on Izuku was astronomical. He was perpetually sore, constantly falling asleep in class, and his hands were covered in a permanent layer of blisters and callouses.

 

But the toll on their cover story was proving to be just as difficult.

 

"So," Inko Midoriya said, her voice eerily calm as she set a massive bowl of rice on the dinner table. "Would either of my sons care to explain why my washing machine is currently clogged with exactly three pounds of beach sand?"

 

Izuku and Toshinori froze.

 

They were sitting at the dining table, both looking like absolute wrecks. Izuku was covered in dirt, his hair sticking up at odd angles, nursing a sore shoulder. Toshinori looked even worse; he had spent the afternoon doing administrative hero work, fighting a minor villain, and then running back to the beach to supervise Izuku’s evening reps.

 

Izuku slowly lowered his chopsticks, panic flaring in his green eyes. He looked at Toshinori for help.

 

Toshinori, the Symbol of Peace, the man who had stared down All For One without blinking, began to sweat profusely under the gaze of a short, plump, green-haired woman.

 

"Well, Mom," Toshinori started, his voice a raspy squeak. "It's... it's a volunteer program."

 

Inko raised an eyebrow, crossing her arms over her apron. "A volunteer program. At six in the morning. Every single day. That requires you to come home looking like you were dragged behind a garbage truck."

 

"Yes!" Izuku chimed in quickly, desperate to back up his brother. "It's for school! Community service! We're cleaning up Dagobah Beach! It looks great on high school applications, especially for U.A.!"

 

Inko narrowed her eyes, stepping closer to the table. She looked at Izuku's arms. The baggy middle school uniform couldn't completely hide the fact that her son's previously stick-thin forearms were suddenly developing lean, hard muscle. She then looked at Toshinori, who was nervously tapping his long fingers against the table.

 

"And why," Inko asked, her gaze boring into Toshinori, "are you going with him, Toshinori? You have an ulcer. You work exhausting hours at the agency. You look like you're about to collapse into your soup."

 

Toshinori swallowed hard. He hated lying to her. He had lied to her for years about his Quirk, his injuries, his very identity. And now, he was dragging her youngest child into his dangerous world, forcing Izuku to lie to her too. The guilt twisted in his ruined stomach.

 

"I'm helping him," Toshinori said, his voice dropping its frantic tone, becoming soft and genuinely sincere. He looked at Izuku, a fond smile touching his lips. "Izu told me he was getting picked on at school. He wanted to get stronger. I couldn't just let him do it alone, Mom. It's a bonding thing. A brother thing. I'm just acting as his personal trainer."

 

Inko's harsh expression instantly melted. The anger vanished, replaced by a deep, maternal sorrow. She looked at Izuku, her eyes welling with tears.

 

"Oh, Izuku," she whispered, walking over and wrapping her arms around her youngest son's head, pressing him against her apron. "Are those boys bothering you again? Why didn't you tell me? You don't have to push yourself so hard just to appease bullies."

 

Izuku hugged his mother back, burying his face in her stomach, deeply ashamed of the deception. "I'm okay, Mom. Really. Toshi-nii is taking great care of me. And... I really want to get stronger. For myself."

 

Inko sniffled, pulling back and looking at Toshinori. "You're making sure he doesn't overdo it, Toshinori? You promise me you're keeping him safe?"

 

Toshinori's blue eyes softened. "With my life, Mom. I promise. I won't let anything happen to him."

 

Inko sighed, a small, watery smile appearing on her face. "Alright. But you are both doing your own laundry from now on. I am not digging rusted nails out of your pockets anymore."

 

As Inko walked back to the kitchen, Izuku and Toshinori let out a synchronized, massive sigh of relief.

 

Toshinori leaned across the table, whispering, "That was too close. We need to start patting you down for sand before we come inside."

 

"Agreed," Izuku whispered back, shoveling rice into his mouth. "But Toshi-nii... what happens when I actually get the Quirk? Mom's going to know I wasn't a late bloomer. Quirks don't just appear at fourteen."

 

Toshinori frowned, leaning back in his chair. "We cross that bridge when we come to it. For now, the secret must be absolute. The less she knows, the safer she is."

 

 

 

By the time autumn rolled around, the air at Dagobah Beach had turned bitterly cold. The biting wind whipped off the ocean, chilling Izuku to the bone despite the sweat pouring down his face.

 

It was month five. Halfway there.

 

Izuku’s progress was phenomenal. A noticeable chunk of the beach was now visible, the sand cleared of the massive appliances that had cluttered it for years. Izuku’s body had transformed; his shoulders were broader, his chest held a firm layer of muscle, and his stamina had skyrocketed.

 

But the mental toll was beginning to show.

 

It was 2:00 AM on a Tuesday. The beach was pitch black, illuminated only by the faint glow of the streetlights on the road above.

 

Izuku was alone. He was currently hauling a rusted, waterlogged sofa by himself, a thick rope tied around his waist, the coarse fibers digging painfully into his skin. His breathing was ragged, his hands bleeding through his gloves.

 

"Just... a little... further..." Izuku gasped, his boots digging into the sand.

 

I'm behind schedule, Izuku’s mind raced, fueled by anxiety and a desperate need to prove himself. Toshi-nii's cough is getting worse. He coughed up so much blood yesterday. His time limit is dropping. He's dying faster, and I'm not ready yet. I have to hurry. I have to take the burden from him so he can rest!

 

With a furious cry, Izuku yanked the rope. The sofa moved three feet, hitting a buried rock and stopping dead. Izuku lost his footing, collapsing face-first into the freezing, wet sand.

 

He lay there, too exhausted to move, tears of frustration stinging his eyes. I'm too weak. I'm just a Deku.

 

"What the hell do you think you're doing?"

 

Izuku flinched. He rolled over, wiping the sand from his face.

 

Standing a few feet away, illuminated by the moonlight, was Toshinori. He wasn't in his muscle form. He was in his skeletal form, bundled up in a thick winter coat, a scarf wrapped tightly around his neck. He looked furious, but beneath the anger, there was a profound, terrifying concern.

 

"T-Toshi-nii!" Izuku stammered, scrambling to sit up, instantly wincing as his over-strained back spasmed. "I... I was just... putting in some extra reps..."

 

"Extra reps?" Toshinori snapped, stepping closer, his long shadow falling over Izuku. "I designed the Aim to Pass plan specifically for your body type. Rest is mathematically factored into your muscle growth. By overworking yourself, you are literally tearing your muscles down faster than they can repair! You are destroying your own body!"

 

"I have to!" Izuku yelled back, the frustration finally boiling over. "I'm behind schedule!"

 

"You are precisely on schedule!" Toshinori countered.

 

"Not for you!" Izuku cried, pointing a trembling, blistered finger at his brother's chest. "I see you, Toshi-nii! I see how much pain you're in when we're at home! I see the blood in the bathroom sink that you try to wash away before I notice! You're running out of time! If I don't get strong enough quickly, you'll have to keep pushing yourself, and... and it's going to kill you!"

 

The wind howled across the empty beach.

 

Toshinori froze. The anger instantly vanished from his gaunt face, replaced by a look of sheer, heartbreaking realization.

 

He hadn't realized Izuku noticed. He thought he had been hiding his deterioration well. But his brilliant, observant little brother had seen everything. Izuku wasn't overtraining for his own sake. He was doing it out of a desperate, panicked need to save his older brother's life.

 

Toshinori let out a long, heavy sigh. His shoulders slumped, the weight of the world seeming to press down on him.

 

He walked over to the rusted sofa Izuku had been dragging. He brushed off some of the dirt and slowly sat down on the cushions. He patted the spot next to him.

 

"Sit with me, Izu," Toshinori said quietly.

 

Izuku hesitated, then unclipped the rope from his waist and trudged over, sitting down next to his brother. He pulled his knees to his chest, shivering in the cold air.

 

Without a word, Toshinori unzipped his heavy winter coat, pulled it off his shoulders, and draped it over Izuku, wrapping the boy in the oversized, warm fabric. Toshinori was left in just his thin t-shirt, shivering slightly, but he didn't seem to care.

 

"I am a terrible older brother," Toshinori whispered, staring out at the dark, rolling ocean waves.

 

"No, you're not," Izuku said instantly, his voice muffled by the collar of the oversized coat.

 

"I am," Toshinori insisted, a bitter smile on his face. "I gave you an impossible task. I placed the weight of the entire world on your fourteen-year-old shoulders, and I didn't even stop to consider how it would affect your heart."

 

Toshinori reached into his pocket and pulled out a small, worn photograph. He stared at it for a long moment before holding it out to Izuku.

 

Izuku took the photo. It was old, the edges frayed. It showed a younger, slightly healthier-looking Toshinori, crying and smiling at the same time, standing next to a beautiful woman with dark, floating hair. She was smiling brightly, wearing a hero costume with a white cape, her hand resting affectionately on Toshinori's shoulder.

 

"Who is she?" Izuku asked softly.

 

"That is my master," Toshinori said, his voice thick with emotion. "Her name was Nana Shimura. She was the seventh wielder of One For All. She is the one who found me, a Quirkless nobody, and told me I could be a hero. She gave me this power."

 

Izuku traced the woman's face. "She looks... really kind."

 

"She was," Toshinori nodded, a tear slipping down his cheek. "She taught me everything. How to fight, how to smile in the face of fear... how to be a Symbol. But..." Toshinori’s voice cracked. "I couldn't save her. When the villain who gave me my scar attacked us... she stayed behind to fight him so I could escape. She died so that I could live, and pass the power on."

 

Izuku gasped, looking up at his brother in horror. "Toshi-nii... I'm so sorry."

 

"I tell you this not to frighten you," Toshinori said, turning to look Izuku in the eyes. "I tell you this because you need to understand the true burden of One For All. It is not just super strength, Izuku. It is a legacy of sacrifice. It is a curse just as much as it is a blessing."

 

Toshinori reached out, placing his massive, calloused hand on top of Izuku’s head, gently running his fingers through the messy green curls.

 

"When I chose you... I was terrified. I am still terrified. You are my baby brother. The thought of placing you in the crosshairs of the monsters that killed my master... it keeps me awake at night. I watch you tear your body apart on this beach, and part of me wants to stop you. Part of me wants to take the power back and tell you to just be a normal kid."

 

Izuku’s heart stopped. "You're... you're taking it back?"

 

"No," Toshinori said firmly, his grip on Izuku's hair tightening slightly in reassurance. "No, I am not. Because I also see the fire in your eyes. I see a boy who runs into the flames when pro heroes stand back. You have a heroic spirit that I could never extinguish, even if I tried."

 

Toshinori leaned closer, his blue eyes intense and pleading.

 

"But you must listen to me, Izuku. You are not a replacement for me. You do not need to rush to take my place so that I can die in peace. I am not going anywhere. I am going to live, if only to see the hero you become. You are not alone in this. We are brothers. We share this burden together."

 

Izuku stared at Toshinori. The frantic, anxious knot that had been winding tighter and tighter in his chest for months suddenly snapped, unspooling into a wave of profound, overwhelming relief.

 

He didn't have to be All Might immediately. He just had to be Izuku. And Toshinori wasn't going to leave him.

 

Tears welled up in Izuku’s eyes again, but this time, they weren't tears of frustration. He launched himself forward, burying his face into Toshinori’s chest, wrapping his arms tightly around his brother's frail waist.

 

"Okay," Izuku sobbed, gripping the fabric of Toshinori's shirt. "Okay, Toshi-nii. I'll take it easy. I'll follow the plan. Just... promise me you won't push yourself either. Promise me you'll stop doing overtime at the agency."

 

Toshinori returned the hug fiercely, resting his chin on Izuku’s head. "I promise, Izu. We pace ourselves. Both of us."

 

They sat there on the rusted sofa for a long time, the Symbol of Peace and his Quirkless successor, holding onto each other in the dark, the ocean waves providing a soothing, rhythmic background to their silent vows.

 

Eventually, Toshinori cleared his throat. "Now, having said that..."

 

Izuku looked up, sniffling.

 

Toshinori’s face morphed into a terrifying, demonic scowl. "If I ever catch you doing unauthorized nighttime reps again, I will personally double your tire-hauling quota and confiscate all of your hero notebooks."

 

Izuku paled instantly. "Y-Yes, sir!"

 

"Good," Toshinori smiled, standing up and pulling Izuku to his feet. "Now, let's go home. I need to sneak you past Mom, or she'll think I'm making you bury bodies."

 

 

 

The final months passed in a blur of sand, sweat, and profound transformation.

 

Winter thawed into spring. The cherry blossoms began to bloom around Musutafu. And on Dagobah Beach, a miracle was taking place.

 

It was the morning of the U.A. Entrance Exams. February 26th.

 

The sun was just beginning to peek over the horizon, casting a brilliant, golden glow across the ocean.

 

Toshinori Yagi drove his beat-up pickup truck toward the beach, a cup of black coffee in one hand, his fingers tapping anxiously on the steering wheel. He was nervous. Today was the day.

 

According to the American Dream Plan, Izuku should have just finished clearing the designated zone—a massive quadrant of the beach that Toshinori had marked with flags. It was enough physical labor to ensure Izuku's body was ready to receive One For All.

 

Toshinori parked the truck near the seawall. He grabbed his jacket, stepping out into the crisp morning air. He expected to see Izuku finishing up the last pile of tires.

 

Instead, he saw nothing.

 

Toshinori stopped dead in his tracks, dropping his coffee cup on the pavement.

 

The beach... was entirely gone.

 

No, not the beach. The trash.

 

Toshinori walked to the railing of the seawall, his jaw hanging open in absolute shock. As far as the eye could see, from the concrete steps all the way to the water's edge, there was nothing but pristine, golden sand. The rusted cars, the refrigerators, the towering spires of garbage—every single piece of it was gone.

 

"He didn't just clear the zone..." Toshinori whispered, his heart hammering against his ribs. "He cleared the entire beach. He completely surpassed my calculations..."

 

A sudden, primal scream shattered the morning silence.

 

Toshinori whipped his head up.

 

Standing on top of the final, massive pile of junk that had been dragged to the edge of the street waiting for the city trucks, was Izuku Midoriya.

 

But it wasn't the scrawny, trembling boy from ten months ago.

 

Izuku stood shirtless in the morning sun, his chest heaving with exertion. Sweat gleamed on his skin, highlighting a physique carved from pure, unadulterated willpower. His arms were thick with corded muscle, his shoulders broad, his core defined. He looked strong. He looked heroic.

 

Izuku threw his head back and screamed at the ocean. It was a scream of triumph, of ten years of pent-up frustration, a roar of a boy who had finally, truly earned his place in the world.

 

He tipped his head forward, exhausted, his legs giving out. He began to fall off the top of the junk pile.

 

Before he could hit the ground, a massive, muscular arm caught him.

 

Izuku gasped, looking up.

 

All Might stood there in his magnificent muscle form, holding Izuku gently by the waist. The Number One Hero looked down at the boy, his blue eyes shining with an immense, overwhelming pride. It wasn't just the pride of a mentor. It was the pride of a brother who had just watched his sibling conquer the impossible.

 

"Excellent work, young Midoriya," All Might said, his booming voice surprisingly soft, trembling with emotion.

 

Izuku smiled, a bright, gap-toothed grin that reached his eyes. "I did it, Toshi-nii. I actually did it."

 

All Might set him down gently on his feet. Izuku swayed slightly, but managed to stand tall.

 

"You didn't just do it, Izu," All Might said, reaching out and clapping a massive hand on Izuku’s bare shoulder. "You went beyond. Plus Ultra. You are more than ready."

 

Izuku’s eyes widened. He knew what this meant. The ten months of hell were over. The Entrance Exams were in a few hours. It was time.

 

All Might reached up, his face taking on a deadly serious, dramatic expression. The wind whipped around them, the golden sunlight framing the Symbol of Peace like a god descending from the heavens.

 

"You have proven yourself worthy," All Might intoned, his voice echoing with the weight of generations. "You have forged your body into a vessel. You have demonstrated the heart of a hero. Now, it is time to inherit the legacy."

 

Izuku stood at attention, his heart pounding in his ears. He imagined a brilliant, glowing light transferring from his brother's chest to his own. He imagined a spiritual connection, a surge of power coursing through his veins.

 

All Might reached up to his head. He gripped one of his golden, spiky hairs. With a sharp tug, he plucked it out.

 

He held the single strand of hair out to Izuku, his dramatic face completely unmoving.

 

"Eat this!" All Might commanded.

 

Izuku stared at the hair. Then he stared at his brother.

 

The grand, epic tension of the moment shattered like cheap glass.

 

"Huh?" Izuku squeaked, his voice cracking.

 

"Eat it!" All Might repeated, thrusting the hair closer to Izuku’s face. "To inherit the Quirk, you have to ingest some of my DNA! It doesn't matter what it is! A hair, a fingernail, blood—but hair is the most sanitary!"

 

Izuku took a step back, his face twisting in absolute disgust. "Are you serious?! I just spent ten months hauling garbage, and the climax is me eating your hair?!"

 

"It's how the power works!" All Might defended, breaking his stoic persona and blushing slightly. "Look, we're on a tight schedule! You need to digest it before the exam starts! Just swallow it down like a pill!"

 

"This is disgusting!" Izuku whined, reluctantly taking the golden hair between his thumb and forefinger. He stared at it as if it were a radioactive spider.

 

"Don't chew it, it'll get stuck in your teeth," All Might advised helpfully.

 

Izuku closed his eyes, pinched his nose, and threw the hair into his mouth. He dry-swallowed it, gagging violently, his face turning green. He coughed, thumping his chest.

 

"Did you get it down?" All Might asked anxiously.

 

"Y-Yes," Izuku coughed, shuddering. "I think so. I don't feel any different. Shouldn't I feel super strong right now?"

 

All Might suddenly deflated in a cloud of steam, Toshinori standing there in his baggy clothes, checking his watch. "It takes about two to three hours to digest and integrate into your nervous system! By the time you sit for the written exam, you should feel the spark."

 

Toshinori reached into his truck and threw a clean white t-shirt at Izuku. "Get dressed. We need to go home, shower, and get you into your uniform. Today is the day you take your first step toward U.A."

 

Izuku pulled the shirt over his head. The fabric stretched tight over his newly developed muscles. He looked at his hands, clenching them into fists. He didn't feel the power yet, but he felt the potential.

 

"Toshi-nii," Izuku said, looking up at his older brother.

 

"Yeah, kiddo?"

 

"Thank you." Izuku’s voice was resolute, carrying a maturity that hadn't been there ten months ago. "For believing in me. For giving me this chance. I swear, I won't let you down. I'll pass that exam, and I'll become a hero you can be proud of."

 

Toshinori smiled, walking over and aggressively ruffling Izuku’s green hair, ruining the dramatic moment. "I'm already proud of you, you little nerd. Now hurry up, Mom is making celebratory pancakes and if we're late, she'll kill us both."

 

As the two brothers walked away from the pristine beach, the sun fully crested the horizon, casting long, triumphant shadows behind them.

 

The training was over. The real test was about to begin.
