The void came first. Izuku's heartbeat was a frantic drum in his chest, each thud amplifying the silence that rushed in as the light vanished. Gamma Field's sterile white snapped to black. His breath caught, his body instinctively tensing, as a piercing klaxon swallowed the ambient sounds, the climate hum and faint echoes of sparring.
Red strobes pulsed. The world stuttered, blood and shadow.
“PROTOCOL GAMMA: FACILITY LOCKDOWN. QUIRK SUPPRESSION FIELD ACTIVATED. ALL PERSONNEL PROCEED WITH NON-QUIRK-BASED EMERGENCY PROTOCOLS.”
The automated voice was calm. Chillingly calm. A counterpoint to the chaos in Izuku’s body. He dropped into a fighting stance. Instinct. He reached for the power under his skin. Lightning. Strength. One For All. Nothing.
Not a fade. An amputation. A cord snapped in Izuku's spine. A cold vacuum where a god had lived. Forgotten echoes of junior high fluttered in his mind: classmates' laughter as he stumbled, notebook clutched tight against his chest. The sneer of a teacher passed over him as if he were invisible. Fourteen again, Quirkless in a world of miracles. Small. Breakable. Alone. Panic clawed at Izuku's throat, cold and sharp. In the void of powerlessness, he felt the weight of every underestimated moment in the void of powerlessness, a lifetime condensed into a single heartbeat.
“Kacchan?” he yelled, his voice thin against the siren’s wail.
No answer. Opposite sides of the arena, mid‑drill. A system fault cascaded; a ceiling grid, weakened by one of Bakugo’s blasts, buckled.
Izuku fumbled at his utility belt, adrenaline making his fingers clumsy. He found the high-intensity flashlight and clicked it on. Its beam sliced through the swirling dust, illuminating wreckage. Izuku swept the beam back and forth, searching. His heart pounded as he finally spotted Bakugo, trapped under a heap of twisted steel and shattered plascrete.
Katsuki Bakugo, the explosion incarnate, was trapped. An I-beam crushed his left leg into an impossible angle. His costume was torn, with white bone visible through the holes.
He was conscious. Crimson eyes, usually blazing with arrogant fire, were wide with shock and pain. He shifted, a guttural sound ripping out of him. His hands in the debris fizzed, flint on wet stone. Useless. The suppression field was absolute. Powerlessness hurt more than the mangled leg.
Bakugo’s usual snarl was replaced by a whisper barely reaching Izuku over the din. "D-Deku, don't just stand there..." he managed, his voice a shadow of its former strength.
Izuku was already moving, his mind stripped of One For All, kicking into its oldest, most practiced gear: analysis. But as he reached the edge of the debris pile, a new sound joined the cacophony.
Heavy, rhythmic steps echoed, closing in. Izuku's beam caught it at the far end, not a typical entrance-exam fodder bot, but a Hunter-class unit: two meters tall, designed for riot control, and built for advanced drills. Its single red eye burned with a cold, menacing glow, and around it lingered a faint, unsettling aroma of ozone, like a storm barely contained. The lockdown had corrupted its programming, this was no longer a training tool; it was a predator.
Izuku looked from the approaching machine to the boy trapped beneath the steel. The boy who had tormented him, who had burned his notebooks, who had told him to take a swan dive off a roof. The boy who was now completely, utterly at his mercy. His mind wavered, caught between the instinct to aid and the weight of their history. Could he really save the person responsible for so much pain? But in that moment of hesitation, Izuku felt a familiar pull - the desire to be a hero, to rise above the past grievances and do what was right, not easy. His heroic instinct, the one genuine, unshakable part of him, left no room for choice. He had to save him.
“Get… off me,” Bakugo snarled, trying to shove Izuku away with one hand as he scrambled over the debris. “I don’t need your fucking help.”
“Your leg is trapped, Kacchan.” Izuku ignored the insults, his mind running numbers, assessing angles, load, and leverage. "Fulcrum's unstable. If I lift, the pile shifts and crushes you."
“Then just fucking blast it!” Bakugo roared, voice cracking with pain. He smashed his fist into the beam; knuckles split, blood streaking the metal, pure, impotent fury.
Izuku didn’t argue. He grabbed a steel pipe and a concrete block and made a lever. He set the pipe under the beam and braced it to lift.
Izuku wedged the pipe, using the concrete block as a fulcrum. He braced and leaned in, pushing down with all his Quirkless strength. The massive beam groaned and shifted, rising a centimeter. As it moved, Bakugo screamed, his body convulsing from pain.
“Hold on,” Izuku gritted out, sweat stinging his eyes. “Almost there.”
The beam lifted just enough. Izuku kicked a smaller piece of debris under it to hold it in place, then scrambled forward, grabbing Bakugo under the arms. He dragged him free, the sound of scraping metal and Bakugo’s ragged, pain-filled breaths filling the air.
Izuku hauled Bakugo up and slung his arm over his shoulder. The weight of his friend was more than just physical; Bakugo hung like a sack of lead, his consciousness flickering in and out. Izuku could feel the pulse of his own heart racing, and could hear the ragged breaths tearing through Bakugo's throat. Each step was a battle, each moment stretched into eternity. A bead of sweat rolled down Izuku's temple, stinging his eye as it mixed with the dust in the air.
Bakugo mumbled something incoherent, his head lolling against Izuku’s shoulder. The oppressive air, thick with tension, pressed down on them both, yet Izuku pressed on.
"Control room, behind that reinforced door," Izuku panted as he staggered toward the arena wall. The goal loomed like a mirage, fifty meters away. "It's shielded. Manual overrides. We seal it." He could feel each shudder in his exhausted limbs, the aching reminder of how far they had to go.
Fifty meters of hell. Bakugo cursed through feverish mutters, volatile with pain. Izuku gritted his teeth and pushed on, Bakugo’s anger a hard ballast in the chaos.
They stumbled through the doorway just as the bot rounded the corner. Izuku slammed the emergency release, and a two-ton steel door hissed shut, the locking bolts thudding into place like gunshots. For a moment, there was blessed silence.
Izuku lowered Bakugo to the floor, back against dead monitors. Small, defensible room. Bakugo pale, sweat-slick, and breathing shallow. Fever was setting in.
“We need to barricade the door,” Bakugo rasped, his strategic mind still firing despite the pain. “Find something heavy. We wait for them to break through, then we jump them.”
“No,” Izuku said immediately, pulling a medkit from a wall compartment. “A direct confrontation is suicide. We have no Quirks, Kacchan. We have to use the environment.”
It exposed the fundamental schism in their philosophies: Bakugo’s unwavering belief in overwhelming force to achieve victory and Izuku’s focus on mitigation and survival, on saving, not just winning.
“You fucking coward,” Bakugo spat, but the insult lacked its usual heat. It was the reflexive jab of a cornered animal.
Izuku ignored him, hands steady: antiseptic wipes and sterile gauze. Bakugo’s leg, deep lacerations, active bleeding. Open, displaced tibia‑fibula fracture. Training surfaced: control bleeding, cover with sterile dressings, check distal pulse and sensation, reduce only if compromised, then splint.
“Kacchan… I have to set it.”
Bakugo’s eyes widened, a flicker of genuine fear cutting through the haze of pain. “Like hell you will. Don’t you touch me.”
“The bone is exposed. If we don’t clean it and stabilize it, you’ll get an infection, or you could sever an artery. You could lose your leg. Or bleed out.” Izuku’s voice was unnaturally calm, the detached tone of an analyst reciting data. Inside, though, chaos reigned. He fought to maintain his composure, to keep his focus from fracturing under the weight of the situation. The sheer urgency threatened to overwhelm him, but this detachment was the only way he could get through this.
He moved fast, before Bakugo could protest. Trauma shears whisked up the shredded pant leg, baring the wound. The intimacy hit like a jolt. Those hands, once weak, later dangerous, now worked steadily over his rawest wound.
“This is going to be the worst pain you’ve ever felt,” Izuku said, his voice soft. He unbuckled a thick leather strap from his own belt. “Bite down on this.”
Bakugo stared at him, his jaw tight, his pride warring with the terror in his eyes. He snatched the strap and shoved it between his teeth.
Izuku took a deep breath, placing one hand on Bakugo’s shin and the other on his thigh. “On three. One… two…”
He didn’t wait for three. He pulled.
Not a scream. A raw, inhuman sound, muffled by leather. His body arched off the floor. Fingers dug into concrete. Izuku held firm. He shook with effort. Tears streaked. He forced the bone back into alignment, a wet, sickening pop.
And then Bakugo went limp, his head slumping to the side. He’d passed out.
Silence returned. Hands shaking, Izuku irrigated and dressed the wound, then splinted the leg with a broken chair leg and undershirt ties.
Bakugo is out cold. Izuku moved. He knew U.A. systems. Yanked a high‑voltage conduit. Stripped the wire. Smashed a server coolant line, slick puddle by the door. Rigged a ceiling monitor on a tripwire. Not a hero-in-training. A survivor. He made the room a trap.
He was just finishing when a heavy thud echoed against the steel door. Then another. Bakugo stirred, his eyes fluttering open. He looked at the door, then at Izuku’s handiwork, a flicker of confusion on his face.
Metal screamed as the door buckled inward. Two Hunter bots stormed in. The first hit the coolant, feet skidding. It flailed into the live wire, 10,000 volts ripped through it. Sparks. Collapse. The second raised its weaponized arm. Izuku yanked the tripwire. The ceiling monitor slammed down, crushing head and torso.
It was over in seconds. Izuku stood panting, his heart racing. He looked at Bakugo.
For the first time since the lockdown began, Bakugo was utterly silent. He stared at the bots' smoking wreckage, then at Izuku. There was no praise, insult, or snarl of contempt. There was only a quiet, grudging, and utterly unmistakable flicker of acknowledgment in his crimson eyes.
The quiet didn’t last. It was replaced by a low, powerful hum that vibrated through the concrete floor. This sound spoke of a different class of machine, of power held in reserve.
A spot on the reinforced steel door began to glow cherry-red. Then white-hot. With a sound like tearing silk, a plasma torch sliced through the metal, carving a perfect circle. The section fell inward with a clang, and a new machine stepped through the opening.
It was sleek, black, and utterly menacing. Unlike the bulky Hunter bots, this one was built for speed and lethality, an Apex-class model designed to test the top ten Pro Heroes. It had no clumsy feet but a tri-track system that would ignore the slick floor. Its single, multifaceted optic glowed with cold, analytical intelligence. It scanned the room, its gaze passing over the destroyed bots and the makeshift traps and finally settling on the two boys huddled in the corner.
Their situation had gone from critical to hopeless.
The Apex bot advanced, its movements smooth and silent. Bakugo struggled to push himself up, his face flushed with fever. He looked at the machine, then Izuku, and his expression shifted. The anger, pride, and aggression seemed to melt away, leaving something raw and terrifyingly vulnerable behind. It was the clarity of a man who knew he was about to die.
“Deku,” he whispered, his voice so rough it was barely audible.
Izuku looked at him, his fear a cold knot in his stomach.
“I…” Bakugo started, then stopped, swallowing hard. The words seemed to pain him physically. “The things I did… to you.”
He wasn’t looking at Izuku, but at some point on the far wall, at a past only he could see.
“Your notebook… in the fountain. All the years… I was a monster.” His breath hitched. The bot was halfway across the room now, taking its time, assessing them. “For… for the roof.”
The words hung in the air, heavy and poisonous. Take a swan dive. The cruelest thing he had ever said, a scar on Izuku’s soul that had never truly healed.
He was sorry. And as those words reached Izuku, he felt the world had tilted on its axis. Shock prickled through him, chased by a wave of unexpected anger. After all this time, after everything, Bakugo's apology felt like a key turning in a lock. Yet, beneath the anger, relief bloomed. Relief that, finally, after years of torment, there was acknowledgment. Tears gathered in Izuku's eyes as he whispered, "For all of it. I’m so sorry."
He took a ragged breath, and the next word he spoke was with an effort that seemed to tear something from his very core. A word he hadn’t used since they were toddlers, a name buried under fifteen years of anger and resentment.
The name struck Izuku with the force of a physical blow. It was an earthquake, shattering the foundations of their entire history. It was an admission, a surrender, an acknowledgment of him as a person, not a pebble in his path. He couldn’t breathe.
The Apex bot raised a weaponized arm, a high-frequency blade humming to life.
Having unburdened himself, Bakugo’s expression hardened into a familiar, fierce resolve. His final heroism was the only way he could win this unwinnable fight. He pushed weakly at Izuku’s chest.
“Run, Izuku,” he commanded, his voice a low, urgent rasp. “Get out of here. Save yourself. That’s an order.”
It was the ultimate sacrifice for a boy built on a foundation of ego: to save the person he had tried so hard to break by offering up his own life. It was his redemption.
Izuku stared at him, the sound of the humming blade and Bakugo’s ragged breathing filling his ears. Run, Izuku. The words echoed in the vast, shocked silence of his mind. For a moment, his body wanted to obey. The instinct for self-preservation screamed at him to flee, to leave the broken boy and his too-late apology behind.
But leaving would be a rejection. It would mean that the impossible, world-altering Izuku's apology meant nothing. It would mean that the boy who had just laid his soul bare deserved to die alone.
He looked from Bakugo’s desperate, feverish face to the advancing machine. And in that moment, something inside him, forged in a lifetime of defiance, hardened into steel.
“No,” he said, his voice quiet but unshakable. He met Bakugo’s stunned gaze. “We get out together, Kacchan.”
He used the childhood name deliberately. It wasn’t the name of a victim anymore. It was a reclamation of their shared history, which he was now choosing to rewrite.
Bakugo stared at him, speechless. In his eyes, Izuku saw not just shock but also a flicker of something else, a fragile, desperate hope.
Galvanized, Izuku’s mind raced. His eyes darted around the room, taking in every detail, every potential weapon, every weakness. His gaze snagged on the ceiling. Running along the length of the control room was a massive, insulated pipe, part of the facility’s primary liquid nitrogen coolant system. He remembered seeing it on the facility schematics during their briefing. Highly pressurized. Extremely volatile.
A plan, insane and suicidal, bloomed in his mind.
He scrambled to his feet, grabbing a jagged piece of metal from one of the destroyed bots. “Hey!” he yelled, his voice cracking. “Over here, you piece of junk!”
The Apex bot’s optic swiveled to him. It had found its primary target.
Izuku didn’t wait. He ran, leading the machine on a desperate chase around the room's perimeter. A plasma blast sizzled past his ear, melting a wall patch into slag. He ducked under a swipe from its humming blade, the wind of its passage stirring his hair. He was using himself as bait, forcing the bot to follow his path and position itself directly under the main coolant conduit.
“Deku, what the hell are you doing?!” Bakugo screamed from the corner.
Izuku risked a glance back. The bot was right where he needed it to be. He planted his feet, pivoted, and threw the shard of metal with all the strength in his Quirkless body.
It flew true, a silver blur, and struck a pressure valve on the pipe with a sharp ping.
For a second, nothing happened. Then, with a deafening roar, the valve ruptured. A torrent of liquid nitrogen exploded downwards in a massive, billowing white cloud. The temperature in the room plummeted instantly. The Apex bot was engulfed. The supercooled fluid flash-froze its internal mechanisms, the sudden, extreme thermal shock causing its metal plating to contract and shatter. It froze solid in a grotesque statue of attack, then toppled over with the sound of a thousand breaking icicles.
The plan had worked. But the force of the rupture created a shockwave of cryogenic air. It slammed into Izuku, throwing him backward like a rag doll. He crashed hard against a steel console, a sickening crack echoing from his shoulder as it dislocated. The intense cold flash-burned his exposed skin before he collapsed to the floor in a heap.
The roar of the ruptured pipe died down to a steady, ominous hiss. The room was plunged into an eerie, freezing silence, broken only by two injured boys' pained, ragged gasps.
Izuku pushed himself up, his left arm hanging uselessly at his side, his body screaming in protest. He crawled to where Bakugo was propped against the wall, slumping beside him. The adrenaline was gone, leaving only a deep, throbbing agony and a profound, shared exhaustion.
They sat there for a long time, not speaking, just breathing in the freezing air.
Finally, Izuku broke the silence. “Why?” he whispered, the word a puff of white in the cold. “Why now?”
Bakugo didn’t look at him. He stared at the shattered remains of the bot, his expression unreadable.
“Because I was going to die,” he said, his voice flat and raw. “And I couldn’t… I couldn’t die with that being the last thing. With you thinking…” He trailed off, struggling for the words.
“I always knew you were strong,” he admitted at last, the confession costing him everything. “Even when you were a Quirkless nobody. You had that stupid, reckless look in your eyes, the same one All Might has.” Bakugo finally looked at Izuku; pain showed in his eyes. “You were always ahead of me, right from the start, and it made me feel weak. So I had to make you feel weaker.” He looked down at his broken leg. “Pathetic, huh?”
Izuku just shook his head, a fresh wave of tears blurring his vision. It wasn't about forgiveness. Not yet. It was about understanding. After a lifetime of violence and anger, he finally saw the scared little boy behind the monster. "I see you now, Kacchan," he said softly, his voice a gentle acknowledgement. And I'm still here."
Hours crept by in a frozen haze. They huddled together against the wall, sharing what little body heat they had left, the hissing of the coolant pipe a constant companion. Izuku’s shoulder was a universe of fire and ice, and Bakugo had drifted into a fitful, feverish sleep.
Then, a flicker. The strobing red emergency lights died, replaced by the steady, clean glow of the primary power grid. The automated voice returned, calm and clear.
“Protocol Gamma lockdown disengaged. System rebooting. All fields returning to normal.”
A moment later, they heard it: the heavy, reassuring thud of hero boots in the corridor outside, followed by the familiar, tired voice of their teacher.
“Problem children? Are you in there?”
The last thing Izuku remembered was the screech of the damaged door being forced open and the silhouette of Eraser Head filling the frame.
He woke to the smell of antiseptic and a heart monitor's soft, rhythmic beep. He was in the U.A. infirmary, the afternoon sun streaming through the window. His left arm was in a sling, his shoulder tightly bound, and the burns on his skin had been treated and bandaged. The pain was a dull, manageable ache, thanks to whatever Recovery Girl had given him.
He turned his head. In the bed next to his sat Katsuki Bakugo. His leg was propped up on a pillow in a reinforced cast. An IV line snaked into his arm. His fever was gone, and a quiet, unnerving calm had replaced the wild, delirious look in his eyes. He was awake, and he was watching Izuku.
The air between them was thick with everything that had happened, with everything that had been said in the frozen dark of the control room. Izuku’s heart was hammered in his chest. He expected another apology, maybe a gruff, half-hearted one. Or maybe, more likely, he expected Bakugo to pretend none of it had ever happened, to retreat behind his walls of anger and pride.
Bakugo did neither. He simply held Izuku’s gaze, his expression uncharacteristically serious, stripped of all its usual bluster. The silence stretched, heavy and meaningful.
Then, he spoke. His voice was low, steady, and held the weight of a vow.
The name should have been an insult. It should have stung, a regression to their broken past. But it wasn’t. The way he said it, it wasn’t the sneering pejorative of their childhood, nor the impossibly intimate “Izuku” of his confession. It was something new. It was a title. His name for his rival. His equal.
The words weren’t a threat of more fighting. They were a promise. A promise of a new beginning, a rivalry re-framed not by hatred and fear, but by a hard-won, brutal, and undeniable respect. A promise that this, whatever this was now, was just the start.
And as Izuku looked into Katsuki Bakugo’s steady crimson eyes, he didn’t feel fear. He felt the first, tentative rays of hope. A slow, dawning understanding spread through him, and for the first time in a very long time, he felt the corners of his mouth lift into a genuine smile.
