Sen looked up at UA's main building, the iconic H-shaped structure gleaming under the morning sun. It felt surreal, like stepping into a memory from another lifetime. He'd seen this view countless times, pixelated and framed by a screen, years and a reality ago. The weight of the moment was not lost on him—a quiet culmination of a second chance he'd never thought he'd get.
He spotted a familiar head of green hair near the entrance, vibrating with a nervous energy so intense it was almost a visible aura. Izuku Midoriya was muttering to himself, his eyes wide as he scanned the towering form of UA, his dream made manifest in concrete and glass. He looked exactly as Sen remembered from the screen, but infinitely more real, more fragile.
He found his assigned written exam room and took his seat. The written test was, as his father had predicted, a breeze. The questions on quirk theory, law, and ethics were elementary to someone who had spent years deconstructing the fundamental energy systems of the human body.
He finished with time to spare, spending the extra minutes simply observing the room. He watched the concentrated frowns, the bitten lips, the frantic scribbling. He saw Izuku a few rows over, muttering softly as he worked through a problem, his brow furrowed in intense focus. The fire was there, banked but burning. It made him smile.
Then it was time for the practical.
The crowd was funneled toward a massive auditorium. Giant screens dominated the front wall, currently displaying the UA emblem. Sen found a seat near the middle aisle, up near the back. He scanned the room. Hundreds of hopefuls buzzed with anticipation, fear, and bravado.
Suddenly the lights dimmed. A spotlight hit the stage, illuminating a figure that needed no introduction yet elicited gasps and awed whispers nonetheless.
"WELCOME, FUTURE HEROES!" Present Mic's voice boomed through the auditorium speakers, amplified by his Quirk to near-deafening levels. He struck a dynamic pose, blonde hair spiking wildly. "TO YOUR UA ENTRANCE EXAM... PRACTICAL TEST! CAN I GET A YEEEEAAAAH?!"
Silence. Stunned silence.
"TOUGH CROWD! NO WORRIES, LET'S GET DOWN TO BUSINESS!" Mic grinned, unfazed, launching into his rapid-fire explanation. "ROBO-RAMBLE TIME, LISTENERS!" Mic bellowed, pacing the stage. "THREE VILLAIN TYPES! ONE-POINTERS, BASIC NUISANCES! TWO-POINTERS, A BIT MORE MUSCLE! THREE-POINTERS, THE BIG BADS! SMASH 'EM, SLICE 'EM, BUTTON-MASH 'EM! POINTS ON THE BOARD! BUT!" He spun dramatically, finger pointed accusingly at the crowd. "LAY A FINGER ON ANOTHER EXAMINEE? INSTA-FLUNK! HEROES PROTECT, NOT POUND, EACH OTHER! GOT IT?!"
"YOU'LL BE ASSIGNED TO ONE OF SEVEN MOCK CITIES!" Mic continued, gesturing to a massive map projection. "BATTLE CENTERS A THROUGH G! YOUR ASSIGNMENT WILL BE ON THE BACK OF IDENTIFICATION CARDS IN FRONT OF YOU!"
A tense silence followed. Then, from the back of the auditorium, a rigid, dark-haired boy shot to his feet, hand chopping the air. "EXCUSE ME, SIR! BUT YOUR ANNOUNCEMENT CONTAINS A GLARING OVERSIGHT!" His voice was loud, sharp, cutting through the residual excitement. "You mentioned three villain types, but the printout shows four. If this is an oversight on UA's part, I have to say I'm disappointed. UA is the best hero school available in Japan, and we as students deserve better. And you with the green hair, stop muttering—it's bothering everyone."
Sen watched the scene unfold with an exhausted smile. The rigid boy's outburst was a perfect, almost comical example of a specific personality type: rule-bound, inflexible, and utterly lacking in social nuance. His public correction of a pro hero was a bold move, born more from a need for absolute order than any real desire to help.
And then he'd pivoted, singling out Izuku. Sen's gaze shifted to the green-haired boy, who immediately clamped his hands over his mouth, his face flushing a brilliant scarlet as he seemed to shrink into his seat. The muttering was a nervous tic, a sign of a mind working too fast for its vocal cords to keep up. To Sen, it was familiar, almost endearing. To this other boy, it was an infraction against decorum.
He's not wrong about the fourth robot, Sen thought idly, his mind accessing the information he'd scanned from his own card. The zero-pointer. A classic obstacle, designed to test for something other than sheer point accumulation. Evasion, rescue, self-preservation. But his delivery... needs work.
Present Mic, to his credit, took the interruption in stride. "A VALID POINT, EXAMINEE 7111! THE FOURTH TYPE IS MORE OF AN OBSTACLE! A ZERO-POINTER! NOT WORTH ANY POINTS, AND TRUTHFULLY, NOT WORTH YOUR EFFORT! IT'S MEANT TO BE AVOIDED! CONSIDER IT AN ULTRA-DIFFICULT STAGE HAZARD! NOW, LET'S MOVE ON, LISTENERS!"
Sen calmly retrieved the small card tucked into the holder on the back of the seat in front of him. He glanced at it.
"Battle Center E." He tucked the card into the pocket of his grey sweatpants. "So I don't have to worry about overshadowing Izuku or Bakugo... good."
The Battle Center loomed before Sen, a sprawling mock cityscape of concrete and steel, complete with towering buildings, narrow alleyways, and wide boulevards.
The air at Battle Center E crackled with a different energy than the auditorium. Here, the bravado had been stripped away, replaced by a raw, nervous tension. Examinees shifted their weight, cracked their knuckles, or stared with fixed intensity at the massive city gates. Sen found a spot near the periphery, away from the most jostling clusters. He closed his eyes for a moment, not in prayer but in focus. He took a single deep breath, feeling the vast, calm lake of his chakra within, the hotter, more turbulent current of the Nine-Tails' energy resting beneath it.
A loud buzzer blared.
"BEGIN!" Midnight's voice boomed over the speakers.
The massive city gates groaned open, and the sea of hopefuls surged forward like a single organism, a tsunami of desperation and ambition. Sen didn't join the initial rush. He stood still for a half-second longer, a rock in the chaotic stream.
He brought his hands together, forming the cross-shaped hand seal. "Multi-Shadow Clone Jutsu."
The sound wasn't loud, but it was pervasive—a series of soft concussive thumps that cut through the din of the charging examinees. Where there had been one silver-haired boy, there were now fifty. A hundred. The number kept climbing until a small army of Sen clones stood in a perfectly disciplined formation, completely blocking the entrance to the mock city.
The few stragglers who hadn't yet charged skidded to a halt, their jaws agape. The clones didn't even look at them. In perfect, terrifying unison, every single Sen turned and shot forward, a silver wave flooding into the city.
The silence that fell over the entrance to Battle Center E was absolute, broken only by the distant, echoing sounds of combat and destruction from within the city. The handful of examinees left standing outside the gate could only stare, their brains struggling to process the impossible sight that had just unfolded before them.
One of them, a boy with extendable fingers, finally found his voice. "Did... did he just... clone himself? An army?!"
Another girl, who could generate small crystals from her skin, simply nodded, her mouth still hanging open. "He's... he's gonna get all the points..."
Inside the mock city, the reality was even more staggering.
The army of Sen clones moved with a terrifying, silent synchronicity. They didn't communicate; they didn't need to.
The UA faculty watched the main screen, which was split into dozens of feeds. But nearly every eye was locked on the feeds from Battle Center E, specifically the ones tracking the silver-haired boy, Sen Yonori.
Present Mic, for once, was speechless. His mouth opened and closed, no sound emerging.
Vlad King grunted, his brow furrowed. "It's a mockery of the test's intentions. He's monopolizing all the points. The other students in that center don't stand a chance."
Ectoplasm, the cloning hero, leaned forward, his expression one of profound professional interest. "The precision... the coordination... they're not just simple duplicates. They're fully autonomous, yet operate with perfect tactical harmony."
"But the rules—"
Vlad started.
"Were to defeat villains and earn points," a new, high-pitched voice chimed in. Principal Nezu had climbed onto the console, a cup of tea held delicately in his paws. His black eyes gleamed with undisguised delight. "He is following the rules to the letter. Quite magnificently, I might add. Look at feed E-7."
They all turned. This feed showed a different scene. A girl with a hydrokinetic quirk had been cornered by two two-pointers, her water jets doing little more than slicking their metal hulls. Just as one raised a crushing arm, a Sen clone dropped from a rooftop above, driving a heel into the robot's optical sensor with enough force to crack the casing and send it stumbling back. The clone didn't finish it. It simply pointed to the dazed robot, then to the girl, gave her a thumbs-up, and vanished in a puff of smoke, leaving her to land the final blow and claim the points.
"It's not just about points for him," Nezu chirped, sipping his tea. "He's farming. He's identifying targets, softening them up, and then redirecting the finishing blow to other examinees who are in position to claim them. He's maximizing the point yield for the entire center while still maintaining an overwhelming lead. It's not a mockery, Vlad. It's a masterclass in tactical efficiency and... oddly, cooperative competition."
Aizawa, who had been watching with his chin buried in his capture scarf, finally spoke, his voice a low, tired rumble. "He's not even breaking a sweat. This is just another day for him." His eyes narrowed. "The question isn't if he passes. The question is what we're supposed to teach someone who walks in the door already like this."
Suddenly a massive tremor shook the mock city of Battle Center E. The ground rumbled, and a building at the far end of the center exploded outward.
The Zero-Pointer.
It was a monstrous behemoth of steel, a towering titan that dwarfed the surrounding buildings, its red eyes scanning the city as it began its slow, destructive march.
The reaction among the remaining examinees was instantaneous panic. They turned and fled, their quest for points forgotten in the face of the apocalyptic machine.
On the screens, the army of Sen clones stopped. As one, all two hundred of them turned their heads to look at the approaching titan.
And as one, they all smirked.
Then, in a series of synchronized puffs of smoke, they vanished. Every single one. The mock city, which had been teeming with silver-haired clones, was suddenly empty save for the fleeing examinees and the looming Zero-Pointer.
In the observation room, there was a collective intake of breath.
"He recalled them," Ectoplasm whispered. "All of them. Instantly. The mental fortitude to maintain that many and then dismiss them all at once..."
"What is he doing?" Midnight asked, leaning forward. "Is he running too?"
The answer came on a single feed, focused on the roof of a building directly in the Zero-Pointer's path. There stood the original Sen, alone now. He watched the approaching behemoth, his expression not one of fear but of calm assessment. He cracked his neck.
Then he leaped.
It wasn't a jump. It was a launch. He didn't use chakra to run up the side of the Zero-Pointer as he easily could have. He chose a more direct, more visceral approach. He met its charge head-on.
He flew through the air, a silver speck against the gargantuan machine. As he soared, a visible aura erupted around him, a shimmering, crimson cloak of raw energy that flickered with a bestial intensity. His Nine-Tailed Version One cloak.
The impact was not a collision. It was an annihilation.
A deafening shriek of tortured metal tore through the mock city, drowning out the panicked screams of the fleeing examinees. The Zero-Pointer's fist, a construct of solid steel larger than a truck, did not simply stop. It disintegrated. It exploded inward in a shower of shredded plating, shattered hydraulics, and sparking wires, as if a bomb had detonated from within.
Sen didn't stop. The force of his punch carried him through the obliterated fist, a crimson comet tearing a catastrophic path up the monster's arm. The Version One cloak flared around him, a contained, raging inferno that melted and vaporized the metal in his wake. He wasn't climbing; he was carving a canyon up its limb.
In the observation room, the silence was absolute. The only sound was the faint crackle of speakers transmitting the sounds of destruction.
Vlad King was on his feet, his chair clattering backward. "He's tearing it apart! That's a city-scale suppression robot!"
Sen reached the elbow joint of the Zero-Pointer. The machine, its programming likely unable to compute an attack of this magnitude, tried to swing its other arm around to swat him away. It was a futile gesture, a giant trying to catch a hypersonic hornet.
Sen didn't even break stride. As the other massive limb swung toward him, he simply raised his left hand. A shriek of a thousand birds sounded through the city as bright red lightning sparked violently around his hand.
The shriek of the Chidori was a sound that didn't belong in the mock city. It was the sound of a thousand furious birds of prey, a high-pitched, violent static that cut through the groaning of metal and the panicked shouts of fleeing examinees. The lightning that wreathed Sen's left hand wasn't the familiar blue of Kakashi's technique but a deep, ominous crimson, dyed by the chakra of the Nine-Tails.
The Zero-Pointer's other arm, a colossal limb of steel and wiring, swung toward him in a slow, powerful arc meant to pulverize buildings. Sen didn't dodge. He met its trajectory, his crimson-lightning-wreathed hand leading.
The impact was not a collision of two solid objects. It was a hot knife meeting butter.
The Chidori, amplified by the raw, volatile energy of the Nine-Tails' cloak, didn't just punch through the arm. It unmade it. The crimson lightning chewed through the metal, severing hydraulic lines, melting actuators, and vaporizing steel plating in a spectacular shower of white-hot sparks and molten droplets. The limb, severed cleanly at the midpoint between the elbow and shoulder, went dead and heavy, its momentum carrying it downward to crash into a mock office building below with a ground-shaking boom.
Sen didn't pause to admire the carnage. The Version One cloak flared around him, a tail of crimson energy lashing out as he used the force of his own destructive momentum to propel himself upward, a red blur shooting toward the Zero-Pointer's main body.
He landed on the broad, flat expanse of its chest, right between its two glowing red optic sensors. The metal beneath his feet was hot from the energy radiating off him. He could feel the immense machine's internal mechanisms straining, trying to compute a threat its programming had no protocol for.
He raised both hands. In his right, a Rasengan formed, a sphere of violently churning energy, its familiar whirring sound a counterpoint to the bestial growl of the crimson cloak. On his left, the crimson Chidori screeched back to life, the red lightning casting a hellish glow on his grinning face.
He drove both techniques forward, plunging them into the chest of the Zero-Pointer.
The effect was cataclysmic.
The Rasengan bored into the armor, grinding it into dust, while the Chidori speared inward, overloading and vaporizing everything in its path. The two techniques met deep within the robot's core, their opposing natures—the pure, chaotic rotation of the Rasengan and the piercing, focused annihilation of the Chidori—creating a critical failure.
For a split second, the Zero-Pointer's red eyes flashed erratically. Then the light in them died.
A deep, internal rumble shook the titan. Fissures of crimson light spiderwebbed across its chest plate from the point of impact. Then, with a final, deafening groan of surrendering metal, the entire upper torso of the Zero-Pointer exploded inward before the whole structure listed to one side and began a slow, inevitable collapse.
Sen backflipped off the falling giant, landing lightly on a nearby rooftop a hundred meters away as the titan crashed to the earth. The impact was seismic, sending a dust cloud rolling through the streets like a tidal wave.
The sudden silence that followed was almost as shocking as the destruction itself.
He stood there on the edge of the roof, his silver hair barely mussed, his grey sweats unstained. He watched the dust cloud settle over the husk of the zero-pointer. Around him, the mock city was eerily quiet. The other examinees had long since fled the area, and the remaining one- and two-pointer robots seemed to have deactivated with the fall of their command unit.
A loud buzzer blared, signaling the end of the exam.
On the rooftop, Sen let the crimson chakra cloak vanish, the raw, bestial energy receding into the calm lake of his own chakra. The red lightning of his Chidori and the swirling energy of the Rasengan dissipated from his hands. He took a deep, steadying breath. The air tasted of ozone, vaporized metal, and absolute victory.
A wide, unrestrained grin split his face.
"Wooo! I am fucking awesome!" he yelled, the words echoing across the suddenly silent battlefield. He pumped a fist into the air, a purely visceral, teenage reaction to having just single-handedly obliterated a skyscraper-sized robot. The giddy euphoria of unleashed power, of successfully executing techniques he'd only ever dreamed of in his past life, was a drug more potent than any he could imagine.
He stretched his arms overhead, rolling his shoulders. "Man, and that was just version one. Imagine if I'd gone all the way. They'd have to rebuild this entire city." He chuckled to himself, the sound loud in the eerie quiet.
>>>>>
After the exam, Sen sat on the wall of UA's entrance. He was scrolling through his phone on what he had figured out was this world's version of Instagram when he spotted the mop of green he was waiting for.
Sen looked up from his phone, a faint, knowing smile touching his lips as he saw the familiar mop of green hair bobbing through the crowd of exiting examinees. Izuku Midoriya looked... different. There was still the lingering aura of anxiety, the hunched shoulders, the nervous wringing of his hands. But beneath it, banked like hot coals, was a new ember of resolve. His eyes, though wide with the aftermath of adrenaline, held a focus that hadn't been there before.
"Yo, Izu, how do you think you did?" he asked, landing next to the green-haired bundle of nervous energy.
Sen's sudden, silent landing beside him made Izuku jolt so hard he nearly stumbled over his own feet. His heart, already hammering from the residual adrenaline of the exam, tried to leap out of his throat.
"Y-Y/n— I mean Sen!" he squeaked, clutching his chest. "Don't do that!"
Sen just grinned, a sharp, easy expression that was both thrilling and mildly terrifying. "So? How'd it go?" he repeated, falling into step beside Izuku as they moved with the crowd leaving the campus.
Izuku's face cycled through a rapid series of emotions—panic, despair, a flicker of hope, then back to a deep, settling anxiety. "I... I don't know," he admitted, his voice barely above a mumble. "It was... a lot. There were so many robots, and everyone was so fast, and then the zero-pointer... I didn't get any points."
"Well, chin up. I'm sure everything will go as it's needed. One bad chapter doesn't define your story. Don't remember who said that, but it fits."
Sen's words, though casually delivered, seemed to settle over Izuku like a warm blanket. The frantic energy buzzing around him quieted slightly. He looked down at his shoes, scuffing the toe of one against the pavement. "One bad chapter... yeah. I... I just hope it wasn't the last chapter."
"It won't be," Sen said, his tone leaving no room for argument. He glanced back at the towering form of UA. "They're not just looking for points. They're looking for heart. And you've got plenty of that." He said it with such simple conviction that it sounded like an irrefutable fact of the universe, like gravity or the sunrise.
Izuku's head snapped up, a fragile hope blooming in his green eyes. "You really think so?"
"I know so," Sen stated. He didn't elaborate. He didn't need to. His own performance had been a spectacle of raw, undeniable power, a statement that would undoubtedly be the talk of the examiners' room. Yet here he was, waiting for the one kid who likely scored zero points, telling him he had what it took. The contradiction was so stark it felt like its own kind of proof.
They walked in silence for a moment, the crowd thinning around them as students went their separate ways, already dissecting their performances with friends or family.
When Sen's acceptance letter came, he was sparring with the twins. The dojo was a whirlwind of controlled chaos. The air hummed with the sound of impact, the sharp thwack of a practice staff meeting a hardened light-shield, the concussive thump of a sonic blast being deflected, and the whisper-quiet shuffle of feet on polished wood.
Sen moved between his siblings, a silver blur of effortless motion. He wasn't fighting to win; he was conducting a symphony of their growth.
Rin, her face a mask of fierce concentration, lunged. A solid, golden lance of light materialized in her hands, thrusting toward Sen's side. At the same time, Ren, from the opposite flank, clapped his hands together, unleashing a visible wave of distorted air, a concussive blast aimed to disorient.
Sen didn't block. He flowed. He pivoted on his back foot, the lance grazing the fabric of his shirt as he leaned away. The sonic wave passed through the space his head had just occupied. In the same motion, his foot hooked behind Rin's advancing ankle, not to trip her but to guide her momentum past him. His open palm met Ren's shoulder, not with force but with a precise push that sent the boy stumbling back two steps to regain his balance.
"It's a good combo," Sen said, his voice calm amidst their panting. "But you're telegraphing the timing, Ren. Rin, you commit too fully to the thrust. Leave yourself an exit strategy."
The twins nodded, sweat beading on their foreheads. They reset their stances, the determination in their eyes undimmed. These sessions were more than training; they were a language, the only way their prodigiously powerful brother knew how to show he cared.
The distant chime of the doorbell echoed through the house.
"Ignore it," Rin grunted, her light lance shifting into a circular shield.
"Focus," Ren agreed, rolling his shoulders and readying another clap.
But Hana's voice floated into the dojo, bright with a mixture of excitement and ceremony. "Sen! It's for you! It's... it's from UA!"
The twins froze mid-movement. The light-shield flickered and vanished. Ren's hands fell to his sides. All three of them turned to look at the dojo's entrance.
The family converged on him, a bubble of anticipatory silence surrounding them. Ken clapped a heavy hand on Sen's shoulder, his grin wide and expectant. Hana had her hands clasped under her chin. Rin and Ren jostled each other for a better view.
Sen turned the envelope over. There, in bold, unmistakable print, was the UA seal. He felt... a quiet thrum of satisfaction. It was the expected outcome, the logical next step. The true test had been the one he set for himself in that mock city. This was just paperwork.
He slid a finger under the flap and tore it open. A small, metallic disk fell into his palm. Before he could examine it, it clicked and whirred, projecting a holographic screen into the air above his hand.
The image resolved into the beaming, exaggerated features of Present Mic.
"YEEEEAH! HEY THERE, LISTENER! CONGRATULATIONS!" Mic's projected voice boomed, making Rin and Ren jump. "YOU ABSOLUTELY BLEW THE ROOF OFF THE PLACE! LITERALLY! WE HAVEN'T SEEN A PERFORMANCE LIKE THAT IN THE ENTRANCE EXAM'S HISTORY! THE RAW POWER! THE TACTICAL BRILLIANCE! THE SHEER AWESOMENESS!"
On the screen, quick cuts showed highlights of his exam. A hundred clones moving in perfect sync. A clone dropping in to save another examinee. And then the main event: a crimson-blurred figure meeting the Zero-Pointer's fist and utterly annihilating it, followed by the spectacular, brutal dismantling of the giant robot.
A point tally appeared in the hologram: Villain Points: 121 – Rescue Points: 203
"NOT ONLY DID YOU SMASH THE VILLAIN POINT RECORD," Mic's voiceover continued, "BUT THE JUDGES WERE SO IMPRESSED WITH YOUR TACTICAL SUPPORT OF OTHER EXAMINEES THAT THEY AWARDED YOU THE HIGHEST RESCUE POINT TOTAL IN UA HISTORY! YOUR TOTAL SCORE OF 324 POINTS IS UNPRECEDENTED! WELCOME, SEN YONORI, TO YOUR HERO ACADEMIA! CAN I GET A—"
The projection cut off as Sen casually clicked the disk again, silencing Mic's impending "YEAH!" mid-word. The hologram vanished. The dojo was left in a ringing silence.
The silence in the dojo was absolute, thick enough to taste. The only sound was the faint hum of the now-deactivated projector disk in Sen's palm. The highlights of his absurd, record-shattering performance hung in the air like ghosts.
Rin was the first to break. Her jaw, which had gone slack, finally worked. "Three... hundred..." she whispered, the number too colossal to say at full volume.
"...and twenty-four," Ren finished, his voice equally hushed. He looked from the disk in Sen's hand to his brother's impassive face, his mind clearly short-circuiting.
Sen shrugged, the motion effortless under his father's heavy hand. He pocketed the disk. "Seems like overkill. A pass would have been sufficient."
"SUFFICIENT?!" Rin shrieked, finding her voice at last. She launched herself at him, not with a weapon but with a bone-crushing hug around his waist. "You blew up the zero-pointer with your bare hands and you call it SUFFICIENT?!"
Ren was right behind her, tackling Sen from the other side in a rare display of unrestrained excitement. "You had an army! A literal army of you! How are you even real?!"
Sen endured the dual tackle-hug with a long-suffering sigh, though a faint, almost imperceptible smirk played on his lips. He patted each of their heads awkwardly. "Yes, yes. It was adequate."
Ken finally threw his head back and laughed, a full, booming sound that echoed through the dojo. "Adequate! He calls the single greatest display of power and control in entrance exam history 'adequate'!" He pulled both twins and Sen into a massive bear hug, lifting all three of them off the ground for a moment. "That's my son! Welcome to UA, kid! You just rewrote the book on what's possible."
Hana joined the group hug, squeezing them all. "We have to celebrate! I'm making a cake!"
>>>>>
"This is it, 1-A. Now that I'm actually standing here, it kinda feels like a dream." The massive, imposing door of Class 1-A loomed before him, a slab of polished steel that felt more like a gateway to a fortress than a classroom. The hallway was quiet, the air smelling faintly of antiseptic and new building materials.
The massive door to Class 1-A slid open with a quiet hiss. Sen stood in the doorway for a moment, taking in the scene. It was exactly as he remembered from a hundred different screenshots and episodes, yet infinitely more real.
His eyes swept over them in a single, efficient glance, his mind automatically cataloging details. A tall boy with glasses was chopping his hand violently at a slouching blond who had his feet propped on a desk. Bakugo. Of course. The explosive blond's scowl was even more potent in person, a cloud of pure, undiluted fury.
Sen's entrance, and his cheerful, utterly casual greeting, sliced through the tense atmosphere like a knife.
"Hello, new friends!"
Every head in the room turned toward him. The chopping motions stopped. The muttering ceased. Bakugo's head snapped around, his crimson eyes narrowing as they landed on Sen. Recognition flashed in them, followed immediately by a fresh wave of rage. The memory of a deadened arm and public humiliation was clearly still raw.
The tall boy with glasses, Iida Tenya, adjusted his spectacles and marched over. "A well-mannered greeting is the foundation of a proper academic environment! However, introducing oneself before the homeroom teacher arrives is highly irregular! I am Iida Tenya from Somei Private Academy!"
Sen just smiled, easy and unbothered. "Sen Yonori. Nice to meet you, Iida." He gave a lazy two-fingered salute, his eyes already scanning the room for his designated desk. "Relax, man. The teacher's not here yet. We've got time to be irregular." He smiled, his eyes traveling to Bakugo.
A low, venomous growl emanated from the blond. "You."
Sen paused, looking down at him with an expression of mild curiosity, as if examining an interesting insect. "Me," he confirmed, his tone flat.
"I don't know what kind of trick you pulled at the exam," Bakugo snarled, his palms cracking with tiny, threatening sparks. "But that shit won't fly here. I'm going to prove you're nothing but a fucking cheater."
Sen's smile didn't falter at Bakugo's snarled threat. If anything, it widened a fraction, a silent, infuriating dismissal that made the blond's eye twitch. "I loathe you too," he said, his tone light and conversational, as if agreeing on the weather. He didn't wait for the inevitable explosion. He simply turned his back on Bakugo, a move of such profound, casual disregard it was more insulting than any counter-threat.
His eyes landed on the source of the frantic muttering in the hallway. Izuku Midoriya was frozen in the doorway, his face pale as he stared at the scene he'd just walked in on: Bakugo seconds from detonating, and the silver-haired exam phenomenon seemingly encouraging it.
"Ah, Izu! You made it," Sen said, his voice shifting into something genuinely warmer. He walked over, completely ignoring the volatile atmosphere he'd just left behind. "Told you it would work out. See? No need to worry." He clapped a hand on Izuku's stiff shoulder, guiding him further into the room as if he were shepherding a nervous kitten.
Izuku stammered, his eyes darting between Sen's calm face and Bakugo's apoplectic one. "S-Sen! What was— I mean, Kacchan, he—"
"Just exchanging pleasantries," Sen replied.
Bakugo's rage finally boiled over. The disrespect of being turned away from, the easy camaraderie with "Deku"—it was too much. "DON'T YOU FUCKING IGNORE ME!" he roared, lunging from his desk. His right hand swung forward, palm already sparking with a building explosion aimed directly at Sen's unprotected back.
The class gasped. Iida shot to his feet, ready to intervene. A brown-haired girl near the front let out a small shriek.
Instead of hitting Sen or Izuku, they both vanished in a puff of smoke, being replaced by chairs and appearing at the front of the class. "That wasn't very hero-like." All heads swiveled. Sen stood there, one hand casually patting the back of a very green-looking Izuku Midoriya, who was hunched over, gagging slightly from the disorienting, high-speed movement. "Pretty cool, right? That was my Substitution Jutsu."
The class erupted.
"Whoa! He just vanished!"
"Did he teleport?!"
"He swapped places with chairs?!"
"How is that even a Quirk?!"
"He saved that green-haired guy!"
Bakugo slowly straightened up, his shoulders trembling. The initial shock was melting away, replaced by a rage so pure and incandescent it seemed to make the air around him waver. He had been made a fool of. Again. In front of everyone. His hands clenched into white-knuckled fists, tiny popping sparks dancing across his palms.
"You... you..." he seethed, the words barely audible over the class's murmuring. His head snapped up, his crimson eyes burning with murderous intent. "YOU BASTARD! I'LL KILL YOU!"
He took a step forward, a deeper, more dangerous explosion building in his palm.
"Enough."
The voice was low, tired, and utterly devoid of warmth. It wasn't loud, but it cut through the noise of the classroom and Bakugo's fury like a scalpel.
Lying on the floor just inside the doorway, wrapped in a bright yellow sleeping bag, was a disheveled, scruffy-looking man. None of them had even seen him arrive. He was like a caterpillar that had suddenly manifested from the shadows. He unzipped the bag just enough to reveal his face, his dark, tired eyes scanning the room with an air of profound disappointment.
"It took ten seconds for you all to shut up after the bell. That's unacceptable. Illogical." His eyes lingered on Bakugo, whose explosive hand was still smoking, and then on Sen, who met his gaze with placid curiosity. "And starting a fight on the first day, before introductions? Don't make me expel you before the opening ceremony."
He fully unzipped the sleeping bag and stepped out, revealing a shabby black jumpsuit and a long, gray capture weapon looped around his neck. "My name is Shota Aizawa. I'm your homeroom teacher."
He tossed the empty juice pouch into a trash can by the door without looking. It went in perfectly.
"Now," he said, his dead-eyed gaze sweeping over them, "because of that pointless display of aggression, we're behind schedule. Everyone, put these on and meet me on the P.E. grounds in ten minutes." He pulled a stack of blue and white P.E. uniforms from his sleeping bag and dropped them on a desk by the door. "No exceptions. Be quick."
Without another word, he turned and walked out, the door sliding shut behind him with a definitive clunk.
The class remained frozen for another second, processing the whirlwind of bizarre events and the terrifying aura of their new teacher.

When 1-A finally arrived at the P.E. grounds, Aizawa was already standing with his usual dead eyes.
"Took you long enough. From here on out, you're only on time if you're early." He grumbled, his voice like gravel. His bloodshot eyes swept over them. "This is a Standard Quirk Apprehension Test. Eight tests: 50-meter dash, grip strength, standing long jump, repeated side steps, ball throw, seated toe-touch, endurance run, and sit-ups."
He listed them off with the monotone of someone reciting a grocery list. "Same standard tests you did in middle school, only this time you'll be using your Quirks." A faint, almost cruel glint entered his tired eyes. "I need to know your limits. What you're capable of. The potential UA saw when it let you in here." His gaze hardened, sweeping across the group. "The one who places last overall in these assessments will be judged to have no potential... and will be expelled."
"That's not fair! We just got into UA—you can't kick us out!" The girl with brown hair and a perpetual blush, Uraraka, had exclaimed.
"And you think natural disasters and villain attacks are? Newsflash: life isn't fair. Get used to it."
The air on the P.E. grounds grew heavy with a mix of excitement and dread. Aizawa's threat of expulsion hung over them like a guillotine, his dead-eyed stare leaving no doubt he was serious.
"Alright," Aizawa droned, holding up a sleek device. "Sen, you scored the highest on the entrance exam. What was your furthest throw in middle school?"
"How the hell would I know?" Sen shrugged.
Aizawa sighed, exhaustion evident. "Just use your quirk and get the ball as far as you can."
Sen caught the ball Aizawa tossed him. It felt light, almost insignificant in his palm. He rolled it on his finger, his expression one of mild contemplation. The rest of the class watched, a mix of curiosity and anxiety on their faces. This was the guy who had obliterated the entrance exam. What would he do with a simple softball?
He didn't adopt a dramatic stance. He didn't channel any visible, overwhelming energy. He simply cocked his arm back, his movements relaxed, almost lazy.
Then he threw it.
There was no grand wind-up, no roar of power. It was just a throw. But the moment the ball left his fingertips, it vanished.
It didn't sail through the air. It didn't arc. It was just gone, disappearing from his hand with a soft crack of displaced air.
A second of stunned silence hung over the field.
Then Aizawa's device in his hand beeped. He looked down at the screen, and for the first time his deadpan expression flickered. A single, tired eyebrow twitched upward almost imperceptibly. He held up the device for the class to see.
The screen read: ∞
A collective, sharp intake of breath swept through the students.
"Infinity?!" Several of them gasped in unison.
"How is that possible?!" Iida chopped his hand through the air, his brain struggling to compute the violation of physics.
"It never landed," Aizawa stated flatly, his voice cutting through the murmurs. He pocketed the device, his eyes narrowing slightly as he regarded Sen. "You propelled it with enough force to achieve escape velocity. Or it burned up in the atmosphere. Either way, it's not coming down."
"This is the metric. I don't expect anyone to score the same as him, but I do expect you to give it your all."
For the 50-meter dash, Sen simply used a basic Body Flicker, appearing at the finish line in a blur before the automated timer could even register a full second. The device spat out a time of 0.02 seconds, a number that made Iida's engine-powered run look like slow motion.
For the standing long jump, he channeled chakra into his feet and cleared the whole sandbox with a chakra leap.
For grip strength, he squeezed the dynamometer with chakra-enhanced strength, destroying the device.
For the seated toe-touch, he simply leaned forward, his movement fluid and effortless. His palms pressed flat against the soles of his shoes, his torso resting comfortably against his thighs. It was a perfect, textbook toe-touch. The most normal thing any of them had seen him do all day.
For sit-ups, Sen was paired with the kid with multiple arms, Shoji. Sen stopped at 250 sit-ups, not because he was tired but because Aizawa said stop.
For repeated sidesteps, the sidestepping test was a blur of motion. Sen didn't just move side to side; he became a phantom, his form flickering across the marked line so fast it was like watching a strobe light. The counter in the measuring device whirred and clicked, its mechanical brain struggling to keep up before finally giving up with a pathetic sputter. A small plume of smoke drifted from its sensor.
Aizawa stared at the smoking device, then at Sen, who had come to a perfect, sudden stop, not even breathing heavily. The teacher's expression was a masterpiece of weary resignation. He simply wrote "a lot" on his clipboard with a sigh that seemed to carry the weight of the world.
Finally it was time for the endurance run. Aizawa pointed to the track. "Distance run. Until I say stop. Use your Quirks if it helps. The goal is to outlast everyone else."
This was a test of stamina, of the depth of one's power. For most, it would be a grueling marathon.
For Sen, it was a stroll.
As the others took off at various speeds—Iida with his engines, Bakugo with explosive bursts, Momo creating a bicycle—Sen simply set off at a light, steady jog. But with every step, a fraction of his chakra flooded into his legs, enhancing his muscles, making the motion impossibly efficient. He wasn't running; he was a perpetual motion machine. Lap after lap, his pace never faltered, his breathing never hitched. He was a metronome of effortless motion in a sea of increasingly gasping, sweating classmates.
One by one they dropped out. Bakugo, fueled by rage rather than endurance, eventually stumbled to a halt, chest heaving. Iida's engines began to overheat, forcing him to stop. Momo just stopped after a while.
Until only two were left: Sen, jogging as calmly as he had on the first lap, and Izuku Midoriya, who was somehow, through sheer, terrifying force of will, still putting one foot in front of the other, his body screaming in protest.
Sen fell into step beside him on the next lap. Izuku was drenched in sweat, his face pale, each breath a ragged gasp. He looked like he was minutes from cardiac arrest. "That's the spirit, Izu. Right, left, right, left. Go go go go!"
Izuku's world had narrowed to a tunnel of agony. Each breath was a ragged, fire-filled gasp, scraping against his raw throat. His legs were blocks of lead, his muscles screaming with every torturous step. The track stretched ahead of him, an infinite, mocking loop of suffering. The world was a blur of green grass and the distant, uncaring figure of Aizawa-sensei.
And then there was Sen.
The silver-haired boy jogged beside him, his breathing even, his face a mask of placid calm. He wasn't even sweating. His presence was a paradox, a beacon of impossible ease in Izuku's personal hell.
"I... can't..." Izuku wheezed, the words tearing from his lungs.
"Sure you can," Sen said, his tone light and conversational, as if they were discussing the weather and not the absolute limits of human endurance. "Your heart's still beating, isn't it? Your lungs are still pulling in air. That's all you need. Just keep the machine running. Don't think about the pain. Think about the next step. And then the one after that."
It was madness. It was the simplest, hardest advice Izuku had ever received. He focused on Sen's voice, on the steady, rhythmic sound of his own feet hitting the track. Right. Left. Right. Left. He wasn't running a race anymore. He was just executing a command. Go.
From the sidelines, Aizawa watched, his capture scarf pulled up to his nose. His dark eyes, usually heavy with exhaustion, were sharp and analytical. He watched Sen, the picture of infinite, untapped stamina, an engine that showed no sign of ever idling, let alone stopping. And he watched Midoriya, the boy who was running on fumes, on sheer, illogical, and frankly concerning willpower alone.
He'd seen the results. He'd seen the infinity symbol. The destroyed grip-strength tester. The sidestep counter that had literally burned out. This wasn't a test for Sen Yonori. It was a formality. A demonstration. The boy was in a league of his own, and the gap between him and the rest of the class wasn't just wide—it was a chasm. But it didn't make him rude or overtly arrogant; he was even taking the time to encourage a poorer-performing student.
"Enough," Aizawa's voice cut through the air, flat and final. "The test is over."
The words were a guillotine dropping. Izuku's body instantly gave out. His legs buckled, and he pitched forward, too exhausted to even put his hands out to break his fall.
He didn't hit the ground.
Sen was there in an instant, a hand under his arm, holding him upright with effortless strength. "See?" Sen said, his voice still infuriatingly calm. "You did it. You didn't stop."
Izuku could only gasp, his vision swimming, his whole body trembling with the aftershock of extreme exertion. He was vaguely aware of Sen half-guiding, half-carrying him back toward the rest of the class, who were all staring with a mixture of awe and horror.
Aizawa waited until the two of them had rejoined the group. The class was silent, the threat of expulsion now feeling incredibly real and immediate.
"Now," Aizawa said, his voice low, "I'll reveal the results."
Aizawa stood before the panting, anxious group of students, the holographic scoreboard flickering to life beside him. The air was thick with tension, each of them mentally calculating their performances, wondering if their best had been enough.
"The results are final," Aizawa stated, his voice devoid of any drama. "The totals are a combination of all eight assessments, weighted for both performance and the creative application of your Quirks."
He tapped the device, and the list appeared in the air:
1. Sen Yonori
2. Momo Yaoyorozu
3. Shoto Todoroki
4. Katsuki Bakugo
5. Tenya Iida
.
.
.
20. Izuku Midoriya
A collective wave of relief washed over most of the class, followed by muttered congratulations and sighs. But all eyes eventually drifted to the bottom of the list. To Izuku Midoriya.
Izuku stared at his name, his face pale. His whole body, still trembling from the endurance run, seemed to shrink. He'd known it was bad.
Aizawa's dead-eyed gaze swept over the class, lingering for a moment on the devastated form of Midoriya before moving to the impossibly calm figure of Sen at the top of the list.
"The results are as you see them," Aizawa stated, his voice flat and final. "I said the student in last place would be expelled, but that wasn't true. It was a logical ruse to make you go all out."
The silence that followed Aizawa's declaration was heavier than any threat could have been. It was the silence of pure, unadulterated emotional whiplash.
For a moment, no one moved. No one breathed. The relief was so sudden, so absolute, that it was physically stunning.
Then the dam broke.
"A... a ruse?!" Iida exclaimed, his hand-chopping motion returning with a vengeance, though now it was fueled by bewildered outrage. "That is highly unorthodox for a pedagogical institution!"
"You mean... we're not expelled?" Uraraka whispered, her hands flying to her mouth as the color slowly returned to her face.
The class erupted into a chorus of overlapping reactions: gasps of relief, nervous laughter, and angry mutters about the emotional turmoil they'd just endured.
Izuku Midoriya simply sank to his knees on the grass, his body finally giving out completely. A ragged, shuddering sob escaped him, a release of the unbearable pressure that had been crushing him. He wasn't expelled. He was still here. He wiped his face with his sleeve, his shoulders shaking.
Aizawa turned and began walking back toward the school building. "We're done here. Change back into your uniforms and return to the classroom. Your syllabus and curriculum packets are on your desks. Read them."
With that, he was gone, swallowed by the shadow of the school, leaving twenty stunned students on the field.
"Alright, go team 1-A! We're awesome—nobody was expelled."
Into this fragile quiet, Sen's voice cut through, cheerful and utterly unconcerned with the psychological torment they'd just endured.
"Alright, go team 1-A! We're awesome—nobody was expelled."
He clapped his hands together once, the sound sharp and final, as if officially closing the matter. He looked around at his shell-shocked classmates, a faint, easy smile on his face. "Alone, you feel nothing but insecurity. That's why we form groups. That's why we have friends. We walk together in order to live a strong life. Makarov Dreyar."
He let the quote hang in the air for a moment. It was an odd, almost whimsical sentiment to drop into the tense atmosphere, a piece of philosophy that felt imported from a completely different, more optimistic story.
"It means we're a team now," Sen translated, his tone matter-of-fact. "So stop looking like you're at your own funeral. We passed. That's the point." He reached down and offered a hand to the still-kneeling Izuku. "Right, Izu? Still in the game."
Izuku stared at the offered hand, then up at Sen's placid face. Slowly a tremulous smile broke through his tear-streaked exhaustion. He took the hand, and Sen pulled him to his feet with effortless strength. "R-right. A team."
The simple act, the casual kindness, seemed to break the spell. The tension began to bleed away, replaced by a dawning sense of collective relief and camaraderie. They had faced their first trial together, and they had all, miraculously, survived.
"Yeah! He's right!" Uraraka chimed in, her voice gaining strength. "We all made it! That's what matters!"
"Indeed!" Iida chopped his hand, though the motion was less rigid than before. "While the method was highly unorthodox, the result is that our class remains intact! We must use this as a foundation for mutual improvement!"
A general murmur of agreement spread through the group. They began to move, heading back toward the locker rooms as a loose cluster, already starting to talk amongst themselves, comparing performances, and marveling at the more spectacular displays they'd witnessed—most of which involved the silver-haired enigma at the front of the pack.
