What if Deku Was Trapped in the Backrooms and Gained Reality Warping Powers

The air in downtown Musutafu tasted of pulverized concrete, ozone, and copper.

 

Izuku Midoriya—hero name: Deku—wiped a streak of sweat and grit from his forehead, his breath coming in ragged, controlled gasps. Green lightning crackled in a chaotic halo around his body, the physical manifestation of One For All thrumming in his veins. All around him, the commercial district had been reduced to a hazardous labyrinth of shattered glass, overturned cars, and cratered asphalt.

 

"Deku! Don't just stand there, you damn nerd! Move!"

 

Katsuki Bakugo’s explosive roar echoed over the din of battle. A split second later, Bakugo rocketed overhead, propelled by a deafening AP Shot that sent him spiraling toward the center of the plaza. A massive plume of frost immediately followed, courtesy of Shoto Todoroki, who was desperately trying to freeze the battlefield to limit their opponent’s mobility.

 

Their target was a man calling himself ‘Fracture.’ He wasn’t a powerhouse with super-strength, nor was he a mastermind with a carefully laid plan. He was a petty thief whose Quirk had suddenly and violently undergone a Quirk Awakening due to trigger-drug exposure. His Quirk, originally a minor ability to bend light around small objects, had warped into a catastrophic spatial-distortion anomaly.

 

Every time Fracture panicked, he threw his hands out, and the fabric of reality tore open. Buildings twisted like taffy. Streetlamps were folded inside out. Cars were sheared perfectly in half, their front ends transported three blocks away while their rear ends remained parked. It was a nightmare scenario.

 

‘His activation time is getting shorter,’ Izuku’s mind raced, his analytical habits kicking in despite the adrenaline. ‘The spatial tears are random, but they radiate outward from his palms. He has no control over where the portals lead. Bakugo is trying to overwhelm him with light and sound to keep his hands down, while Todoroki is restricting his footwork. It’s a solid strategy, but Fracture is getting more erratic. If he releases a radial distortion…’

 

"Get away from me!" Fracture shrieked, his voice cracking with drug-induced hysteria. He swung his arms in a wide, frantic arc.

 

The air itself seemed to shatter like a mirror. A jagged, violet tear in space ripped across the plaza. Todoroki’s glacier was cleanly severed, the top half vanishing into the void. Bakugo was forced to abort his mid-air assault, using a blast to violently alter his trajectory, narrowly avoiding a pocket of space that instantly inverted a traffic light.

 

"He's panicking! His range is expanding!" Tenya Iida’s voice crackled through the comms in Izuku’s ear. "We need to evacuate the remaining civilians! There's a shelter under the bank!"

 

Izuku’s eyes darted across the battlefield. He had One For All active at 8% Full Cowl. He was ready to sprint, ready to incapacitate the villain, but then he saw it.

 

Near the shattered entrance of the First National Bank, pinned beneath a fallen piece of masonry, was a woman. Next to her, a little girl clutching a stuffed rabbit was crying hysterically. They were trapped against the solid, reinforced concrete wall of the bank.

 

And Fracture, blinded by Bakugo’s smoke and flailing wildly, was aiming both of his glowing hands directly at them.

 

‘He’s going to hit them!’

 

There was no time to yell. There was no time to formulate a multi-step plan. The hero’s instinct, the core of Izuku Midoriya’s very being, took over before his brain could even process the math.

 

One For All surged. Eight percent spiked to twenty. The green lightning flared violently, tearing the asphalt beneath his iron-soled boots as he launched himself forward.

 

"Smash!" Izuku roared, not as an attack, but to focus the power into his legs.

 

He moved faster than the eye could track, a blur of teal and green cutting through the dust. He saw the violent, violet distortion wave erupt from Fracture’s hands. It rippled through the air, completely silent, warping the light around it like a heat mirage. It was moving toward the mother and daughter at terminal velocity.

 

Izuku collided with the mother and child, wrapping his arms around them and pivoting his body. He threw them forcefully, yet safely, out of the distortion wave's trajectory, sending them sliding across the smooth marble floor of the bank’s lobby.

 

But Izuku had no momentum left to save himself.

 

He was flush against the solid, unyielding concrete exterior wall of the bank. He braced for impact, crossing his arms over his chest, expecting the spatial Quirk to slice him, crush him, or teleport him into the sky.

 

The violet wave hit him.

 

But it didn't hurt.

 

There was no explosion. There was no tearing of flesh or breaking of bone. Instead, there was a sensation that Izuku’s brain could not comprehend. It felt as if his body had suddenly become a phantom. The solid concrete wall at his back did not resist him.

 

He felt himself falling backward. Not through a hole in the wall, but into the wall.

 

For a fraction of a second, his vision was flooded with an impossible geometry. He saw the inside of the concrete, but not as stone and rebar. He saw a wireframe of reality, a digital void of static and non-existence. The sounds of Bakugo shouting, the roaring fires, the sirens—they were all instantly muted, as if someone had pulled a plug on the universe.

 

And then, he was falling.

 

It was a terrifying, stomach-dropping plunge through absolute nothingness. Izuku flailed, trying to activate Blackwhip, trying to grasp onto something, anything. But there was only the rushing sensation of vertigo.

 

THUMP.

 

Izuku slammed into the ground. Hard.

 

The wind was knocked violently from his lungs. He lay there for a moment, his vision swimming, his chest heaving as he gasped for air. He expected to open his eyes to the rubble of the city, or perhaps a dark alleyway miles from the fight, assuming the villain’s Quirk had simply teleported him.

 

He opened his eyes.

 

He was not outside. He was not in Musutafu. He was not anywhere that made sense.

 

Izuku slowly pushed himself up on his hands and knees. The first thing that assaulted his senses was the smell. It was a thick, overwhelming stench of old, moist carpet. It smelled like a basement that had flooded decades ago and had been left to fester. It was a stale, suffocating musk that immediately made his nose wrinkle.

 

The second thing was the sound.

 

Bzzzzzzzzzzzz.

 

It was a loud, aggressive, continuous hum. It sounded like a massive swarm of electric bees, or a poorly wired electrical transformer pushed to its absolute limit. Izuku winced, instinctively reaching up to cover his ears, but the sound seemed to penetrate his skull.

 

He stood up, his red boots squelching slightly against the floor.

 

He looked down. He was standing on a damp, sickeningly yellow carpet. It stretched out in every direction.

 

Izuku raised his head, and his emerald eyes widened in sheer, unadulterated confusion.

 

He was in a room, or rather, a series of partitioned spaces. The walls were covered in mono-yellow wallpaper, patterned with a faded, repeating floral design that looked like it belonged in a forgotten 1970s office building. The ceiling was low, made of cheap acoustic tiles, with recessed fluorescent light fixtures. Some of the lights flickered erratically, casting long, shifting shadows, while others blared with a harsh, surgical brightness.

 

"What... what is this?" Izuku whispered. His voice sounded flat, devoid of echo, swallowed immediately by the damp walls and the droning lights.

 

He tapped his earpiece. "Iida? Uraraka? Kacchan? Can anyone hear me? Aizawa-sensei?"

 

Static. Just a dead, flat hiss that blended perfectly with the hum of the lights above him.

 

Izuku took a deep breath, forcing down the sudden, icy spike of panic in his chest. ‘Calm down. Analyze the situation. This is a hero’s job. You’ve been hit by an unknown Quirk. You are trapped in an unfamiliar environment. Rule one: Assess your condition. Rule two: Assess your surroundings. Rule three: Formulate a plan of action.’

 

He checked himself over. His hero costume was dirty from the fight with Fracture, his iron soles scuffed, and his gloves slightly frayed, but he was uninjured. He summoned One For All, letting the familiar warmth pool in his chest. A faint green glow illuminated the sickly yellow wallpaper around him. His Quirk was intact. That was a relief.

 

‘Okay. So, what is this place? A teleportation Quirk? Did Fracture send me inside a building somewhere in Japan? An abandoned office complex?’

 

Izuku began to walk. His boots made a disturbing squelch-squish sound with every step. He rounded a corner, expecting to see a window, a door, a reception desk—anything that indicated human habitation.

 

Instead, he found another hallway. And another. And another.

 

The architecture made no logical sense. There were walls that jutted out at strange angles, creating blind corners and pointless alcoves. There were supporting pillars in the middle of hallways that blocked the path. There were rooms with no doors, accessible only through bizarrely shaped archways. Everything was uniform. Everything was yellow. Everything smelled of mold.

 

After ten minutes of walking, Izuku stopped. He unzipped one of his utility pouches and pulled out a small, battered notebook and a pen. It was a habit born of a lifetime of Quirk analysis.

 

‘Hypothesis 1: I am in a physical location in the real world. A very large, empty building. If I pick a direction and walk in a straight line, I will eventually find an exterior wall or a window.’

 

Izuku picked a wall to his left and marked an 'X' on it with a piece of charcoal from his pouch. He took a compass out of his belt. The needle was spinning wildly, completely useless.

 

‘Magnetic interference. Or maybe... this isn't Earth.’ He pushed that terrifying thought away. He couldn't afford to think like that yet.

 

"Okay. Straight line."

 

Izuku took a deep breath. Green lightning flared around him. “One For All: Full Cowl—Five Percent!”

 

He took off. He bounded down the yellow hallways, moving at roughly forty miles per hour. He was careful not to break the walls, weaving through the jagged, non-Euclidean architecture with the agility he had honed under Gran Torino and Endeavor.

 

He ran. And he ran. And he ran.

 

Room after room flashed by. Sometimes the hallways were narrow, forcing him to slide under low-hanging bulkheads. Sometimes they opened up into massive, sprawling expanses of empty carpet with hundreds of structural pillars. But the color palette never changed. The dampness never faded. The deafening hum of the fluorescent lights remained a constant, maddening companion.

 

He ran for what felt like an hour. In the real world, at his speed, he would have crossed an entire city.

 

Gradually, he slowed to a jog, and then a walk, his chest heaving, sweat pouring down his face. The ambient temperature of the place was uncomfortably warm, stiflingly so.

 

Izuku leaned against a yellow wall, panting. He looked ahead. Endless yellow. He looked behind him. Endless yellow.

 

"This... this isn't a building," Izuku muttered, his voice trembling slightly. "A building has limits. A building has structure. This is... an illusion? A mental landscape?"

 

‘Hypothesis 2: Fracture’s Quirk put me in a genjutsu-style mental prison. My physical body is unconscious on the battlefield in Musutafu, and my mind is trapped in a construct.’

 

"If it's an illusion, it has a breaking point. A shock to the system."

 

Izuku squared his stance. He looked up at the cheap acoustic ceiling tiles. If he couldn't find a way out horizontally, he would go vertically. He would break the simulation.

 

He planted his feet on the damp carpet. Power surged from his core, radiating outward in violent arcs of red and green energy. The air around him whipped into a miniature gale, the pressure pushing against the yellow walls.

 

“One For All: Forty-Five Percent!” Izuku shouted, the power vibrating in his vocal cords.

 

He coiled his legs like springs and launched himself straight up, his fist pulled back. “Manchester... SMASH!”

 

His knuckles slammed into the ceiling with the force of a falling meteor. He expected the ceiling to shatter. He expected the shockwave to rip the roof off the building, exposing the sky. He expected the illusion to crack like glass.

 

Instead, an impossible physical phenomenon occurred.

 

The moment his fist made contact, the acoustic tiles and the plaster behind them deformed. But they didn't break. They stretched. The material behaved like a non-Newtonian fluid, or memory foam. It absorbed the entire kinetic output of a 45% Smash—enough force to level a city block—and simply dimpled upwards, swallowing his arm up to the elbow.

 

There was no sound of breaking stone. There was no shockwave. The kinetic energy was just... deleted.

 

Izuku hung in the air for a second, his eyes wide in disbelief.

 

Then, the ceiling pushed back.

 

With a sickening, wet sound, the ceiling forcefully expelled his arm and snapped back into its perfectly flat, undisturbed shape. The recoil sent Izuku plummeting back to the floor. He landed hard on his back, staring up at the ceiling.

 

There wasn't a single scratch on it. The fluorescent light next to the impact zone hadn't even flickered.

 

"No way," Izuku breathed, scrambling to his feet, a cold dread washing over him. "That was forty-five percent. I could have blown a hole through UA’s blast doors with that."

 

He reached out and touched the wall next to him. It felt like normal drywall covered in cheap wallpaper. It felt real. The damp carpet beneath his fingers felt real. The sweat on his brow felt real.

 

This wasn't an illusion. This wasn't a mental prison. The terrifying truth began to settle in his bones, freezing his blood.

 

He had fallen out of the world.

 

He was in a place where the laws of physics—conservation of mass, kinetic energy, Euclidean geometry—did not apply. The universe he knew had boundaries. This place... this place felt infinite. It was a glitch. The wrong side of the wall.

 

"Okay, Izuku. Breathe. Breathe," he whispered to himself, pacing in a small circle. "You're a hero. Heroes survive. Aizawa-sensei said spatial Quirks are the most dangerous because they rewrite rules. But every Quirk has a limit. Fracture's Quirk has to have a time limit, or a range limit. I just have to survive until the effect wears off, or until someone finds a way to pull me back."

 

He looked down at his notebook. He crossed out Hypothesis 1 and Hypothesis 2.

 

He was about to write Hypothesis 3: Extra-dimensional space when the lights flickered.

 

It wasn't the erratic flickering of a broken bulb. All the lights in the immediate vicinity dimmed simultaneously, plunging the hallway into a deep, sickly twilight, before buzzing back to full brightness.

 

Then, he heard it.

 

It was a sound that made every single hair on Izuku’s arms stand up. It came from a dark corridor to his right.

 

It started as a low, wet scratching sound. Like long, jagged fingernails dragging across the drywall. Then came the breathing. It was heavy, ragged, and wet, echoing unnaturally down the twisting corridors.

 

Finally, a howl tore through the air.

 

It was a guttural, terrifying sound. It sounded vaguely human—like a man screaming in unimaginable agony—but twisted, distorted, as if the vocal cords had been shredded and reassembled incorrectly. It carried a primal hostility that struck directly at the amygdala.

 

Izuku instantly dropped into a fighting stance. Green lightning enveloped him once more, casting sharp shadows against the yellow walls.

 

"Who's there?!" Izuku called out, his voice firm despite the ice in his veins. "I am a Pro Hero in training! Show yourself!"

 

The scratching stopped. The heavy breathing paused.

 

Then, the sound of galloping began. It wasn't the sound of boots running. It was the sound of heavy, bare hands and feet slapping against the wet carpet, moving at a terrifying speed.

 

‘It’s coming from the right. Fast.’

 

Izuku focused his eyes on the corner of the corridor. He prepared to dodge, to analyze the villain's Quirk, to subdue them without lethal force.

 

A creature rounded the corner, and the breath hitched in Izuku’s throat.

 

It wasn't a villain. It wasn't human. It barely looked like a Nomu, though it shared their grotesque horror.

 

It was a humanoid entity, but it crawled on all fours like a deranged canine. Its limbs were elongated and double-jointed, bending in sickening, unnatural ways. It was entirely naked, its skin a pale, sickly gray, stretched tight over emaciated bones. But its head... its head was a nightmare. A thick curtain of matted, greasy black hair obscured its face, but beneath the hair, Izuku could see a cavernous mouth filled with jagged, broken teeth, set in a jaw that unhinged far wider than any human’s.

 

It didn't have eyes. It just had smooth skin where the eyes should be.

 

It stopped ten feet from Izuku, its head twitching violently from side to side. It let out another distorted, human-like scream and lunged.

 

"Blackwhip!" Izuku yelled.

 

Dark, crackling tendrils of energy erupted from his right arm. The entity was fast—faster than a normal human—but Izuku had trained against the fastest heroes in Japan. He lashed out with Blackwhip, the tendrils wrapping securely around the creature’s torso and front limbs in mid-air.

 

Izuku anchored his feet, preparing to slam the creature into the ground.

 

But as Blackwhip constricted, the creature didn't behave like flesh and blood. It shrieked, thrashing wildly. Where the energy tendrils dug into its skin, there was no blood. Instead, the creature’s flesh seemed to fuzz, like static on an old television. It was glitching.

 

With a surge of terrifying, hysterical strength, the creature ripped its arms outward, tearing its own spectral flesh to slip through the gaps in Blackwhip. It hit the carpet, scrambled wildly, and lunged at Izuku’s throat.

 

Izuku ducked under the gnashing teeth, feeling a spray of foul, black saliva hit his cheek. He pivoted on his heel, driving a 20% One For All empowered elbow directly into the creature’s spine.

 

CRACK.

 

The sound of shattering bone echoed loudly. The creature was sent skidding across the wet carpet, slamming into the baseboards of the yellow wall. It lay there for a moment, twitching spasmodically.

 

Izuku breathed heavily, keeping his guard up. "Stay down," he warned.

 

The creature’s head slowly rotated. It turned a full one-hundred and eighty degrees, a sickening series of pops and cracks accompanying the movement. The cavernous mouth opened, and it let out a low, gurgling laugh.

 

Then, it stood up. On two legs this time. Its broken spine seemed to knit itself back together with a series of grotesque snaps. It towered over Izuku, nearly eight feet tall, its arms dangling past its knees.

 

Izuku’s tactical mind raced, but the variables were all wrong. ‘It doesn't feel pain the same way. It heals instantly, like a high-tier Nomu. But it doesn't have multiple Quirks... it feels like it belongs here. Like this place made it.’

 

The creature charged again, throwing a wild, elongated arm at Izuku like a whip.

 

Izuku dodged backward, but the space was too confined. The creature’s claws raked across his chest, tearing the fabric of his hero costume and drawing four shallow lines of blood. The sting of pain grounded him.

 

"Okay. You want a fight?" Izuku muttered, his eyes narrowing. The fear was receding, replaced by the indomitable will of a hero. "I don't know what you are, but I won't let you kill me."

 

He activated Float. He lifted off the ground by just an inch, removing the friction of the wet carpet. He engaged One For All at 30%, the green lightning illuminating the hallway like a strobe light.

 

The entity roared, charging forward.

 

Izuku didn't dodge this time. He stepped directly into the entity’s guard. He parried the clawed hand with his left forearm, ignoring the sting, and drove his right fist deep into the creature’s chest.

 

“St. Louis SMASH!”

 

The impact was devastating. The creature’s ribcage caved in completely. The force of the blow lifted the eight-foot monster off its feet and sent it rocketing down the hallway. It crashed through a freestanding architectural pillar, tumbling end over end until it came to a halt fifty feet away.

 

Izuku landed, gasping, waiting for it to get back up.

 

The creature didn't move. Its body lay in a broken heap. And then, something bizarre happened. The creature didn't bleed out. It didn't die in a conventional sense. Its body began to dissolve into black, tar-like static. It sank into the wet yellow carpet, leaving no trace behind except for the shattered pieces of the pillar it had hit.

 

The hallway fell deadly silent once more. Only the droning bzzzzzz of the lights remained.

 

Izuku touched the fresh claw marks on his chest. He looked at the blood on his fingers. Real blood. Real pain. Real danger.

 

"They aren't villains," Izuku whispered, the horrifying realization washing over him. "They're predators. And I'm in their territory."

 

He looked down the endless, winding maze of yellow walls. He realized that running randomly was a death sentence. He needed a base. He needed water. He needed to figure out the rules of this reality before it consumed him.

 

He turned around to head back to the intersection where he had fought the creature, hoping to retrace his steps to his original starting point. He wanted to find the ‘X’ he had drawn on the wall.

 

He took three steps and froze.

 

The intersection was gone.

 

Where there had been a four-way crossroad just moments ago, there was now a solid wall covered in mono-yellow wallpaper. Izuku stared at it, his mind refusing to process the visual information. He walked up to the wall and placed both hands flat against it. It was solid. Unyielding.

 

He hadn't heard anything move. He hadn't felt an earthquake. But while he was fighting, while his back was turned, the architecture of the space had shifted. It had rewritten itself.

 

His footprints on the damp carpet? Gone.

 

The ‘X’ he had drawn? Gone.

 

The path back to where he fell in? Gone.

 

He was locked in a labyrinth that shifted when he wasn't looking. A labyrinth populated by monsters that defied physics.

 

Izuku Midoriya stood alone in the suffocating silence of Level 0. He looked down at his trembling hands, the faint green glow of One For All feeling agonizingly small against the vast, crushing infinity of the Backrooms.

 

For the first time since he received his Quirk from All Might, Izuku truly felt powerless. He was completely, utterly, and hopelessly isolated. And as the lights above him flickered again, casting deep, reaching shadows down the corridor, Izuku realized that escaping this place wouldn't just require a hero.

 

It would require a miracle.

 

Or, a dark thought whispered in the back of his mind as his Quirk hummed in resonance with the fluorescent lights, it would require him to stop playing by the rules of reality altogether.

 

 

 

Time did not exist here. Not in any way that mattered.

 

Izuku Midoriya sat cross-legged on a rusted metal grate, his back pressed against a scalding iron pipe that ran the length of a claustrophobic, dimly lit tunnel. In his trembling, soot-stained hands, he held a dented aluminum canteen. He unscrewed the cap and took a slow, measured sip.

 

The liquid inside tasted faintly of almonds and vanilla water, sweet but with a sickly, artificial aftertaste that coated his tongue. It was the only thing keeping him alive. He had found his first bottle in the sprawling, foggy concrete warehouses of what he mentally designated as "Level 1," sitting perfectly centered on a wooden pallet like a cruel video game item. At first, he had refused to drink it, terrified of poison. But after what felt like five days of agonizing dehydration, his survival instinct had overridden his caution. It turned out the Almond Water healed him, soothing his frayed nerves and dulling the constant ache in his muscles.

 

Izuku swallowed, grimacing as the warm liquid slid down his raw throat. He capped the canteen and hooked it onto his utility belt.

 

He looked down at himself and let out a hollow, raspy exhale. He looked nothing like the Symbol of Hope he was training to become. His UA hero costume, once a vibrant teal, was stained gray with concrete dust and dark, rust-colored patches of dried blood. The left sleeve had been torn away entirely during a frantic escape from a horde of faceless creatures in Level 1. His iron soles were scratched and dented, and his gloves were little more than frayed rags wrapped around his knuckles.

 

He pulled out his notebook. The cover was waterlogged and peeling. He flipped past pages of meticulous Quirk analysis from a lifetime ago—notes on Bakugo, Todoroki, Uraraka. He flipped to the back, to the pages covered in frantic, jagged handwriting.

 

Level 0: The Yellow Rooms. Endless. Safe but maddening. Found stairs.

Level 1: Concrete warehouse. Foggy. Entities present. Hounds. Scratches heal fast with the Almond Water.

Level 2: (Current). Pipe dreams. Blistering heat. 110 degrees? Machinery noises. Very dangerous. DO NOT TRUST THE SHADOWS.

 

Next to the notes were tally marks. One hundred and forty-two tallies.

 

Did one tally equal a day? A shift in the lights? A time he had slept? Izuku couldn't remember when he started making them, only that the act of scratching ink onto paper proved he still existed.

 

"I'm still here," Izuku whispered to the empty, sweltering tunnel. His voice was a dry rasp, barely audible over the mechanical groaning of the pipes around him. "My name is Izuku Midoriya. I go to UA High School. My mom is Inko Midoriya. I like katsudon. I am a hero."

 

He repeated the mantra. He had to. The isolation was an invasive, living thing. It clawed at the edges of his sanity, whispering that the world above had never existed. It told him that there had never been a blue sky, or a laughing girl with gravity powers, or a blonde boy screaming explosions. It told him he had always been here, in the heat and the dark, a rat trapped in the walls of reality.

 

Izuku closed his eyes and tried to meditate, falling back on the one connection he thought was unbreakable. He slowed his breathing, ignoring the stifling heat of Level 2, and reached inward. He reached for the core of One For All, seeking the warm, roaring bonfire of power and the comforting presence of the past users. He needed to hear the gruff voice of Daigoro Banjo, or feel the gentle reassurance of Nana Shimura.

 

He opened his inner eye, expecting to see the vast, dark void illuminated by the glowing chairs of the vestiges.

 

Instead, his mental landscape was horrifying.

 

The void was gone. The thrones were gone. The warm, radiant bonfire of One For All had been snuffed out. In its place was a sky of infinite, sickly yellow acoustic tiles, stretching on forever. The ground was wet carpet. And where the bonfire should have been, there was a jagged, twisting tear in the air, glowing with violent, chromatic static—cyan and magenta tearing at the edges of his soul.

 

"Nana?!" Izuku shouted in his mindscape, panic seizing him. "First User?! Banjo?!"

 

There was no answer. Just a deafening, electrical buzz.

 

Bzzzzzzzz.

 

Izuku snapped his eyes open, gasping for air as if he had been submerged in ice water. He gripped his chest, his heart hammering against his ribs.

 

They were gone. The connection was severed.

 

Tears pricked the corners of his eyes, cutting tracks through the grime on his cheeks. One For All was a Quirk deeply tied to the living reality of his world. It was a network of human wills. But here, outside of reality, that network had no signal. He was completely cut off.

 

But One For All was not gone. It was just... changing.

 

Izuku looked at his right hand. He concentrated, calling on Full Cowl. Usually, this would manifest as a web of glowing, red energy veins beneath his skin, followed by the arcing discharge of green lightning.

 

This time, the energy that pooled in his palm felt cold. It didn't feel like a stockpiled physical strength; it felt like a pressurized vacuum, a void desperately trying to fill itself.

 

Suddenly, his hand flickered.

 

It was the only way to describe it. For a fraction of a second, the image of his fingers fragmented into horizontal blocks of color, shifting an inch to the left before snapping back into place, accompanied by the distinct crackle of audio feedback. It looked exactly like a tracking error on a corrupted VHS tape.

 

Izuku dropped his Quirk instantly, recoiling in horror.

 

"What... what is happening to me?" he breathed.

 

His analytical mind, though battered, began to put the pieces together. One For All was fundamentally a Quirk that stockpiled power. For decades, it had stockpiled the physical strength and willpower of its users. But now, it was separated from its native dimension. Nature abhorred a vacuum, and so did One For All. Cut off from the physical energy of Earth, the Quirk was beginning to gorge itself on the only ambient energy available.

 

It was stockpiling the Backrooms.

 

It was absorbing the anomalous, reality-bending frequency of the liminal space. The glitch. The non-Euclidean physics. It was all flowing into the empty bonfire inside his chest, rewriting the very DNA of his Quirk.

 

A sudden, violent hiss of steam from a nearby valve violently snapped Izuku out of his thoughts.

 

He stood up quickly, his bruised muscles protesting. The ambient temperature was rising rapidly. Level 2 was notoriously volatile. The cramped tunnels of pipes and grating would occasionally experience massive thermal spikes, forcing him to keep moving.

 

He slung his tattered backpack over his shoulder—containing his notebook, two more canteens of Almond Water, and a flashlight he had scavenged off a decomposing, faceless corpse days ago—and began to walk.

 

The heat grew oppressive, blurring his vision. The metallic clanging and groaning of the pipes grew louder, masking the sound of anything that might be stalking him in the shadows. He navigated a maze of right angles and dead ends, the metal grating burning through the cracked soles of his boots.

 

Eventually, he reached a dead end. But this one was different. Set into the floor was an industrial service hatch, propped slightly open. The heat emanating from the tunnel was becoming unbearable; the paint on the pipes was literally blistering and peeling before his eyes.

 

He had to go down.

 

Izuku gripped the heavy iron handle of the hatch and yanked it open. A blast of shockingly cold, stagnant air hit him in the face. It smelled of ozone, copper wire, and old dust. Without hesitation, he slipped through the opening and climbed down a rusted iron ladder into the pitch-black abyss below.

 

He climbed in absolute darkness for several minutes before his boots finally hit solid ground. It felt like cold concrete.

 

He unclipped the flashlight from his belt and clicked it on. The beam of light sliced through the oppressive gloom, illuminating a massive, cavernous space.

 

This was Level 3: The Electrical Station.

 

It was a sprawling, chaotic nightmare of industrial architecture. Massive electrical transformers, tangled webs of thick black cables, and humming generators stretched out as far as the beam could reach. The air was cold, but thick with a metallic tang that made Izuku’s teeth ache. The only illumination came from the sparse, flickering sparks of exposed wiring and the dim, ambient glow of gauge dials on the machinery.

 

It was a labyrinth of metal and shadow.

 

"Okay," Izuku whispered, his breath pluming in the cold air. "Keep moving. Find the breaker rooms. There might be an exit door."

 

He began to navigate the narrow paths between the towering electrical hummocks. The silence here was different from Level 0. It wasn't an empty silence; it was a heavy, expectant silence, layered over the low-frequency hum of the generators. It felt like walking through the belly of a sleeping beast.

 

Crunch.

 

Izuku stopped dead.

 

The sound had come from his left. He slowly panned his flashlight over.

 

There, lurking in the gap between two massive, humming transformers, was a face. It had no body. It was just a pair of wide, glowing, hyper-realistic white eyes and a massive, ear-to-ear grin filled with razor-sharp teeth, floating in the absolute darkness.

 

A Smiler.

 

Izuku knew about these. He had encountered one briefly in Level 2. They were drawn to light and movement.

 

Slowly, carefully, Izuku reached for the switch on his flashlight. He clicked it off.

 

Plunged into absolute blackness, Izuku held his breath. He didn't move a muscle. In the dark, the Smiler’s glowing eyes and teeth vanished, but he could hear it. A wet, clicking sound, like a predatory insect, echoing off the metal walls.

 

It was hunting.

 

Izuku took a silent step backward, sliding his foot across the concrete.

 

"Izuku...?"

 

The voice froze the blood in his veins.

 

It came from directly behind him. It was a girl's voice. Soft, sweet, and trembling with fear.

 

"Izuku, it's so dark... please, help me..."

 

It was Ochaco Uraraka’s voice.

 

For a fraction of a second, the hero’s instinct screamed at him to turn around, to reach out, to save his friend. But the cold, brutal logic of the Backrooms slammed the door on that hope. Uraraka wasn't here. She was safe on Earth.

 

This was a Skin-Stealer. A predatory entity that mimicked the voices of loved ones, pulled straight from the victim's own mind, to lure them in before wearing their flesh.

 

Izuku didn't turn around. Instead, he channeled the mutated, chilling energy of his altered Quirk into his legs.

 

"Smash," he whispered grimly.

 

He launched himself forward, diving into the narrow gap between the machinery just as a heavy, wet thud echoed right where he had been standing. He clicked his flashlight back on, sweeping it behind him.

 

Standing there was a nightmare of biology. It looked vaguely human, but its proportions were grotesquely stretched. It was covered in a patchwork of rotting human skin—some pale, some dark, clumsily stitched together with coarse black hair. Its face was a drooping, hollow mask of flesh, from which Uraraka's voice emanated in a sickeningly perfect mimicry.

 

"Why are you running, Izuku? I thought you were a hero..." the Skin-Stealer gurgled, its jaw flapping unnaturally.

 

"Shut up!" Izuku yelled, the psychological warfare tearing at his already fragile mind.

 

He didn't have time to fight. The sudden burst of light and noise had attracted the Smiler. Above him, on the ceiling, three more pairs of glowing, manic grins appeared in the darkness.

 

He was surrounded.

 

Izuku sprinted down the narrow industrial corridor, his flashlight bouncing erratically. The Skin-Stealer pursued him on all fours, its patchwork limbs slapping wetly against the concrete, surprisingly fast. Above, the Smilers glided through the shadows, their chittering clicking growing louder.

 

‘Think, think, think!’ Izuku’s mind raced. ‘I'm exhausted. I haven't slept in days. I can't outrun them forever. I need to fight, but physical blows barely work on these things!’

 

He rounded a corner and skidded to a halt. A massive, electrified fence blocked the path, sparking violently. It was a dead end.

 

He turned around. The Skin-Stealer was slowly blocking the only exit, rising to its full, eight-foot height. Its hollow, fleshy eyes stared at him. The three Smilers descended from the ceiling, their grinning faces illuminating the dark corridor with a ghostly, pale light.

 

"Don't worry, Izuku," the Skin-Stealer said, but this time, the voice shifted mid-sentence. It morphed from Uraraka’s sweet tone into the harsh, arrogant growl of Katsuki Bakugo. "You were always a useless, Quirkless Deku anyway. Give it up."

 

The psychological blow was staggering. Izuku backed up until his shoulders hit the electrified fence, the static making the hairs on his neck stand up.

 

"I'm not..." Izuku gasped, his chest heaving, his vision swimming with exhaustion. "I'm not useless."

 

The Skin-Stealer lunged, its massive, clawed hands reaching for Izuku’s face.

 

Izuku threw out his left arm. "Blackwhip!"

 

He expected the familiar, solid, dark tendrils to burst from his skin and bind the monster. Instead, what erupted from his arm was a violent, chaotic spray of digital static. It wasn't a physical whip; it was a stream of corrupted visual data, humming with the sound of a dial-up modem shrieking in agony.

 

The static lashed out and struck the Skin-Stealer’s arm.

 

The entity didn't recoil from physical force. Instead, where the static touched it, the creature’s arm simply... stopped existing. There was no blood, no severed flesh. The forearm and hand were perfectly, cleanly deleted, replaced by a localized blur of pixels that quickly faded into empty air.

 

The Skin-Stealer let out a horrific, garbled scream of confusion and agony.

 

Izuku stared at his arm in shock, the static retreating into his skin like liquid mercury. ‘What did I just do? That wasn't Blackwhip. That wasn't force. That was... erasure.’

 

Before he could process the impossible nature of his new power, the Smilers attacked. They darted through the air, massive jaws opening to consume him in darkness.

 

Driven purely by adrenaline and the absolute terror of death, Izuku abandoned all restraint. He didn't calculate percentages. He didn't worry about breaking his bones. He reached into the void in his chest, grabbed hold of the stockpiled, anomalous glitch energy, and pulled with everything he had.

 

“One For All: One Hundred Percent!”

 

There was no green lightning. There was no shockwave of wind pressure.

 

Instead, the world broke.

 

A localized dome of reality distortion expanded outward from Izuku’s body. The air around him turned into a violent kaleidoscope of cyan, magenta, and glaring white static. The deafening hum of the machinery was completely drowned out by the piercing, high-pitched squeal of audio feedback.

 

To Izuku, his own body felt weightless. He looked at his hands, and they were vibrating so fast they appeared transparent, overlapping with past and future positions of themselves.

 

The three Smilers hit the distortion dome. They didn't crash into a shield. They hit a spatial error. The grinning faces were stretched horizontally across space, smearing like wet paint across a canvas, before they fragmented into thousands of glowing pixels and vanished entirely from the code of the Backrooms.

 

The Skin-Stealer, missing an arm and frantic, threw itself at Izuku.

 

Izuku didn't throw a punch. He didn't have to. The anger, the isolation, the sheer desperation to survive culminated in a single, instinctive gesture.

 

He raised his right hand, his eyes glowing with a terrifying, hollow static light, and swiped his hand through the air as if dismissing a notification on a screen.

 

ZZZZZT-CRACK.

 

The space between Izuku and the Skin-Stealer ripped open, revealing a blinding, wireframe void beneath the floor of Level 3. The Skin-Stealer fell into the tear, its body instantly unraveling into ribbons of raw spatial coordinates. It didn't even have time to scream.

 

As quickly as it opened, Izuku clenched his fist, and the fabric of reality snapped shut, seamlessly welding itself back together.

 

The localized dome of static collapsed. The silence of the electrical station rushed back in, heavy and oppressive.

 

Izuku dropped to his knees, gasping for breath. The backlash of the power wasn't physical. His bones weren't broken. His muscles weren't torn. Instead, his brain felt like it was on fire, flooded with a sudden influx of impossible mathematical data—the spatial coordinates of every pipe, wire, and atom within a fifty-foot radius. He felt an intense wave of nausea, dry-heaving onto the cold concrete floor.

 

He knelt there for a long time, the adrenaline slowly draining from his system, replaced by a cold, hollow dread.

 

He slowly lifted his right hand.

 

It looked normal. Covered in dirt and soot, wrapped in a frayed glove. But as he focused his eyes, he saw it. The air around his fingertips was subtly rippling, like heat rising off asphalt on a summer day. Reality was warping around him, passively bowing to his presence.

 

He hadn't hit that monster. He hadn't fought it. He had hacked the physical laws of the space and edited the monster out of existence.

 

Izuku remembered the terrifying realization he had back in Level 0. This place doesn't play by the rules of reality.

 

He looked at his rippling hand, the weight of a terrifying truth settling heavily on his young shoulders.

 

One For All had adapted to save him. It had stockpiled the anomaly. He was no longer just a boy with super strength, trapped in an endless, liminal hell.

 

He was becoming the system administrator.

 

"I'm not just surviving anymore," Izuku whispered, his voice sounding subtly layered with a faint, metallic echo.

 

He stood up, his green eyes flashing momentarily with a burst of television static. The shadows in the electrical station seemed to recoil from him, the darkness pulling back to give him a wide berth. The hunter had become the apex predator.

 

Izuku gripped his flashlight, turning his gaze deeper into the labyrinth of Level 3. He didn't just want to find an exit anymore. He wanted to understand this power. He wanted to master the glitch. Because if he could warp this reality, he could force it to open a door back home.

 

And heaven help whatever entities stood in his way.

 

 

 

Absolute darkness is not merely the absence of light. In Level 6 of the Backrooms, the darkness was a physical entity. It was a heavy, suffocating fluid that pressed against the eardrums and coated the inside of the lungs. It swallowed sound, absorbed heat, and actively hunted the minds of anyone foolish enough to wander into its depths. Normal light sources—flashlights, flares, even the ambient glow of fire—were devoured within inches of their source, rendering vision entirely obsolete.

 

Izuku Midoriya stood in the center of the void, completely unbothered.

 

He didn't need a flashlight anymore. He didn't need his eyes.

 

A month ago—or perhaps a year ago, time was a fluid, meaningless concept now—the darkness of Level 6 would have driven him utterly mad. He would have been stumbling blindly, terrified of the silent, unseen predators that stalked the pitch-black corridors. But now, as he stood with his hands resting casually in the pockets of his shredded, soot-stained hero pants, the darkness was no longer a threat.

 

It was a canvas.

 

‘Everything is math,’ Izuku thought, his mind operating at a terrifying, hyper-accelerated frequency. ‘Matter, energy, space, time. In the real world, the math is rigid. It’s governed by strict, unyielding laws. But here… the math is just a suggestion. It’s a poorly written code, held together by sheer anomalous willpower.’

 

He closed his eyes, though it made no difference to his vision. Instead of looking with his retinas, he looked with his Quirk.

 

One For All had completely synchronized with the liminal glitch of the Backrooms. When he focused, the absolute blackness around him melted away, replaced by an intricate, glowing wireframe of neon-green and cyan geometry. He could see the structural mesh of reality itself. He saw the coordinates of the invisible walls, the floor beneath his boots, and the dense, algorithmic clusters of code that represented the entities lurking in the shadows.

 

About thirty feet to his left, an algorithmic cluster was moving toward him. It was an Insanity—a wretched, emaciated entity born from human wanderers who had completely lost their minds to the dark. It was crawling along the ceiling, preparing to drop on him and tear his throat out.

 

Izuku didn’t move into a fighting stance. He didn't summon a shockwave of wind.

 

He simply raised his right index finger and tapped the air, as if striking a key on an invisible piano.

 

Ping.

 

A localized ripple of distortion emanated from his fingertip. Izuku didn't attack the creature; he simply rewrote the gravitational constant in a ten-foot radius around it.

 

Instead of pulling down at 9.8 meters per second squared, the gravity in that specific pocket of space instantly inverted and multiplied by fifty. The Insanity didn't even have time to shriek. It was violently crushed against the ceiling by the sheer force of its own artificially multiplied weight, flattening into a harmless, two-dimensional smear of data that quickly dissolved into static.

 

Izuku lowered his hand, his expression entirely neutral.

 

"Too easy," he murmured. His voice sounded strange. The acoustics of Level 6 normally swallowed sound, but Izuku had subconsciously altered the air density around his head so he could hear himself perfectly.

 

He continued walking through the abyss. He was experimenting. Testing the boundaries of his apotheosis.

 

He looked at the invisible wall to his right. ‘Let’s try transmutation.’

 

He placed his palm against the cold, unseen drywall. He imagined the molecular structure of the gypsum and paper. He held the image of solid steel in his mind. He pushed a fraction of a percent of his glitch-stockpiled energy into the wall.

 

A wave of pixelated, chromatic static washed over the surface. The sound of shifting matter—like a thousand metallic puzzle pieces sliding into place—echoed in the dark. Izuku tapped the wall. It rang with the dull, heavy clank of reinforced titanium. He had fundamentally altered the atomic structure of the environment just by thinking about it.

 

He took a step forward, and suddenly, he felt a sharp, phantom pain in his chest.

 

It wasn't a physical wound. It was a deep, spiritual ache. It was the feeling of a tether snapping.

 

Izuku stopped dead in his tracks. He looked down at his hands. The skin on his fingers was constantly, subtly vibrating, blurring slightly at the edges like a low-resolution image.

 

‘I'm losing it,’ he realized, a spike of genuine, human terror piercing through his cold detachment. ‘I'm adapting too well. I'm becoming a part of this place.’

 

The power was intoxicating. It made him feel like a god looking down at an ant farm. When you can delete a monster from existence with a thought, when you can turn stone into steel, when you can walk on the ceiling, the fear of death vanishes. But without the fear of death, the value of life begins to erode.

 

"I am Izuku Midoriya," he said aloud, his voice trembling slightly, desperate to hold onto the humanity slipping through his fingers. "I am a hero. My hero name is Deku. I... I save people with a smile."

 

He forced himself to smile in the darkness, but his face felt stiff, foreign.

 

He needed an anchor.

 

Izuku crouched down and placed both hands flat on the invisible floor. He closed his eyes and summoned every ounce of memory he had of his life before the Backrooms. He thought of his dorm room at UA. The exact dimensions. The smell of the detergent his mother used on his sheets. The placement of his All Might posters. The clutter of his desk.

 

He fed the memory into the engine of One For All, and commanded the Backrooms to obey.

 

ZZZZZZZT!

 

A blinding flash of localized reality-warping erupted from his palms. The absolute darkness of Level 6 was violently pushed back by a rapidly expanding sphere of light and matter.

 

When Izuku opened his eyes, he was no longer standing in the void. He was sitting on the floor of his UA dorm room.

 

The sunlight streaming through the window was warm. The bed was unmade. The All Might figures were perfectly lined up on the shelves. Izuku gasped, a ragged sob tearing from his throat. He scrambled to the bed, burying his face in the blankets, breathing in the scent of home. For a minute, he let himself break. He wept, the tears hot and real against his grimy skin.

 

But as the initial wave of profound relief subsided, the uncanny valley set in.

 

Izuku sat up and wiped his eyes. He looked closer at the room. It was close, but it was wrong.

 

The sunlight outside the window wasn't moving; it was a static image burned into the glass. The books on his desk had covers, but when he opened them, the pages were entirely blank, filled only with the faint watermark of television static. He looked at the All Might poster on the wall. At first glance, it was perfect. But as he stared, he realized All Might’s smile was too wide, his eyes completely hollow, and his fingers were fused together in a bizarre, AI-generated blur.

 

It was a cargo-cult replica. The Backrooms could manifest his memories, but it didn't understand the soul behind them.

 

Izuku slowly walked over to the mirror attached to his closet door.

 

He stared at his reflection. He was battered, his hair wild and matted, his clothes in ruins. But that wasn't what terrified him.

 

His eyes, once a bright, vibrant emerald green, were now glowing with a soft, pulsing ring of digital cyan and magenta. And faint, jagged lines of static were slowly tracing their way up his neck, resembling circuit board pathways etched into his flesh.

 

He was mutating. The more he used the reality-warping, the more the Backrooms integrated into his biology. If he didn't find a way out soon, he wouldn't just be trapped here; he would become an entity himself. A guardian of the glitch.

 

"No," Izuku whispered, staring into his own glowing eyes. "I am not a monster. I am a hero."

 

He slammed his fist into the mirror.

 

It didn't shatter into glass. Instead, the entire dorm room instantly collapsed like a popped balloon, folding in on itself in a rush of wind and static, leaving Izuku standing once more in the oppressive dark of Level 6.

 

But he was done experimenting. He was done hiding.

 

Izuku looked down at his feet. Through the wireframe mesh of reality, he could see a bizarre, fluctuating cluster of code beneath the floorboards of the universe. It was a different level entirely. And it was emitting a massive amount of anomalous energy.

 

"Time to go," he said.

 

He stomped his foot. He didn't break the floor with strength; he simply deleted the floor’s collision mechanics.

 

He fell straight through the solid ground, noclipping out of Level 6 and plunging into the abyss.

 

 

 

The transition was violently jarring.

 

Izuku fell for ten seconds through a kaleidoscope of flashing colors before crashing hard onto a floor covered in thick, plush, sickeningly colorful carpet.

 

Instantly, his senses were assaulted.

 

The absolute silence of Level 6 was replaced by the tinny, distorted sound of upbeat 1980s pop music echoing from unseen, blown-out speakers. The pitch-black void was replaced by a blinding barrage of neon colors.

 

Izuku stood up, brushing confetti off his shoulder.

 

He was in a massive, sprawling room that looked like a twisted amalgamation of a children’s indoor play area and a cheap pizza arcade. The walls were painted in loud primary colors—reds, blues, and yellows—decorated with crude, painted smiles and balloons. Long folding tables were scattered around, draped in cheap plastic tablecloths and piled high with what looked like birthday cake and half-empty cups of Almond Water.

 

But the smell… the smell was atrocious.

 

Beneath the cloying scent of vanilla frosting and cheap plastic was the heavy, metallic stench of rotting meat and dried blood.

 

Izuku’s eyes locked onto the walls. Interspersed between the painted smiles were massive, dark crimson smears. Handprints. Bloody streaks leading toward dark, winding corridors that branched off from the main party room.

 

He knew where he was. The notes he had scavenged from dead wanderers in Level 1 had warned him of this place above all others.

 

Level Fun.

 

"Such a cruel joke," Izuku muttered, his glowing eyes scanning the room.

 

"A wanderer! A new friend!"

 

The voice was bubbly, high-pitched, and entirely synthetic. It sounded like a cartoon mascot whose audio chip was degrading.

 

Izuku turned slowly.

 

Standing on the other side of a cake-laden table was a creature. It was humanoid, roughly the size of an adult, but its skin had the texture and color of smooth, yellow leather. It wore no clothes, save for a party hat strapped to its head. Its face was featureless, except for a wide, cartoonish smile carved deeply into its flesh, oozing a dark, syrupy fluid. Instead of hands, its arms ended in bloody stumps, though other variations he’d read about possessed human hands grafted onto their bodies.

 

It was a Partygoer. One of the most intelligent, sadistic, and dangerous entities in the entire Backrooms. They hunted for sport, torturing wanderers and turning them into 'cakes.'

 

"Come join the party =)" the Partygoer chirped, stepping out from behind the table. It pointed one of its bloody stumps toward a dark corridor. "We have so much cake! And games! It's so much fun here!"

 

Izuku didn't flinch. His reality-warping sight analyzed the creature. It was complex code. High intelligence, high physical strength, and a hive-mind connection.

 

"I'm not interested in a party," Izuku said, his voice cold, projecting perfectly over the obnoxious pop music.

 

The Partygoer paused. Its carved smile didn't change, but it tilted its head at an unnatural, ninety-degree angle. The bubbly facade dropped slightly.

 

"You don't want to play? But everyone plays. Those who don't play become the cake =)"

 

"You're covered in blood," Izuku stated flatly. "You hunt people. You torture them. I am a Pro Hero. That makes you a villain."

 

The creature let out a sound that resembled a giggle, but it sounded like a saw blade cutting through bone.

 

"Hero? There are no heroes here. Only guests. And hosts."

 

Suddenly, the upbeat music cut out, replaced by a low, rhythmic thumping.

 

From the dark corridors, from the plastic play tubes suspended from the ceiling, from beneath the tables, they emerged. Ten, twenty, fifty. Over a hundred Partygoers stepped into the neon light. Their leather-like yellow skin gleamed. Some held rusted knives; others simply flexed their elongated fingers or bloody stumps.

 

They formed a massive, enclosing ring around Izuku.

 

"So many friends to play with!" the hive-mind spoke, a hundred synthetic voices overlapping in a horrifying, dissonant chorus. "Let's see how long the hero can scream =)"

 

In the past, Izuku would have evaluated his odds. He would have looked for an escape route, calculated the structural integrity of the ceiling, or prepared to break his own bones to unleash a 100% Smash to clear a path.

 

Now, he just felt a profound sense of weariness.

 

"You think you're hunters," Izuku said quietly. He didn't raise his voice, but the localized acoustics amplified his words so they reverberated in the chest cavity of every entity in the room. "You think you control this level."

 

The Partygoers screeched, a deafening sound of predatory hunger, and lunged forward en masse. A wave of yellow leather, carved smiles, and bloody weapons descended upon him.

 

Izuku closed his eyes and took a deep breath.

 

‘I am a hero,’ he reminded himself. ‘I don't kill. Even monsters. If I slaughter them, I become the villain. I become the darkness.’

 

He opened his eyes. The cyan and magenta rings flared with blinding intensity. He spread his arms wide, unleashing the full, stockpiled force of One For All’s reality-warping engine.

 

“Override Command,” Izuku commanded.

 

He didn't unleash physical force. He unleashed a master-level code rewrite over the entirety of Level Fun.

 

The effect was instantaneous and absolute.

 

A dome of pristine, glowing, brilliant white light erupted from Izuku’s body, expanding outward at the speed of sound. Where the light touched the charging Partygoers, they did not burn. They did not explode.

 

They froze mid-air, caught in the grip of a god.

 

The light hit the blood-stained walls. The crude painted smiles and smeared handprints dissolved, washing away like chalk in a heavy rain. The neon red and blue paint peeled back, revealing a soft, impossibly clear sky-blue color.

 

The disgusting, plush carpet beneath Izuku’s feet unspooled, the synthetic fibers turning green, sprouting, multiplying. Within three seconds, the floor of Level Fun was transformed into a field of lush, vibrant, living spring grass.

 

Izuku walked forward. With every step, the folding tables and plastic play tubes melted down, reshaping themselves. Wooden trunks twisted upward toward the acoustic tile ceiling. Branches spread out, and thousands of delicate, pink cherry blossoms bloomed in an instant, raining down softly onto the grass.

 

The horrifying stench of rotting meat was entirely erased, replaced by the crisp, clean scent of fresh air and blooming flowers.

 

The Partygoers, suspended in the air, began to panic. Their hive-mind shrieked in terror as they realized their very existence was being edited. They tried to thrash, tried to attack, but their physical forms were melting.

 

"You don't get to hurt people anymore," Izuku said, walking among the frozen horde.

 

He snapped his fingers.

 

The heavy, leather-like flesh of the Partygoers began to thin out, becoming perfectly smooth and buoyant. Their dense muscles and bones evaporated into light gas. Their carved, bloody smiles morphed into printed, harmless, classic yellow smiley faces.

 

In a matter of seconds, the army of sadistic monsters was gone.

 

In their place, hundreds of ordinary, yellow Mylar balloons bobbed gently in the air, their strings trailing softly over the spring grass. Izuku had transfigured them completely. He hadn't killed them; he had simply removed their capacity for violence, turning their horrific aesthetic into a literal, harmless joke.

 

Izuku stood in the center of the cherry blossom grove he had created inside the Backrooms. The upbeat 80s music was gone, replaced by the gentle rustle of leaves and a soft, phantom breeze.

 

He had done it. He had completely conquered a level. He had overwritten the malicious code of the Backrooms with his own soul.

 

He looked around. The space felt different now. It didn't feel liminal. It didn't feel hostile. It felt anchored. It was no longer Level Fun.

 

It was Level Midoriya.

 

By claiming dominion over this space, Izuku could feel the edges of the simulation. Because he now owned the 'room,' he could find the door.

 

He sat down on the soft grass beneath a cherry blossom tree and closed his eyes. He didn't search for physical exits. He reached out with his mind, extending his awareness through the glitch, past the walls of his newly forged level, into the infinite, twisting architecture of the Backrooms.

 

He was looking for a specific vibration. A radio frequency in the cosmos.

 

He sifted through millions of empty, dead universes. He felt the terrifying, crushing weight of the Void. He felt the gaze of entities vastly older and more terrible than the Partygoers stirring in the deep levels, drawn to the massive beacon of power he had just unleashed.

 

But he ignored them. He kept searching.

 

‘Musutafu. UA. My mom. Kacchan. Uraraka.’

 

He visualized them. He tuned his frequency to the emotional resonance of his home.

 

And then, faintly, like a whisper across a canyon, he heard it. The chaotic, beautiful, buzzing hum of his native reality. The world of Quirks.

 

Izuku’s eyes snapped open.

 

He stood up, raising both hands in front of him. He grabbed the empty air as if it were a physical curtain. His fingers sank into the fabric of space, the air distorting and cracking like thick ice.

 

"I'm going home," Izuku declared.

 

With a guttural roar, channeling the absolute maximum output of One For All, Izuku pulled his hands apart.

 

The universe screamed.

 

A massive, jagged fissure ripped open in the center of the cherry blossom grove. Beyond the tear, there was no endless carpet or fluorescent lights. There was a swirling, chaotic vortex of violent spatial energy—a raw, unfiltered tunnel cutting directly through the dimensional barrier. At the very end of the tunnel, infinitely far away yet right in front of him, he could see a pinprick of natural, golden sunlight.

 

The portal was unstable. It was fighting him, trying to snap shut, but Izuku held it open with sheer willpower, his arms shaking, his body glowing with the chaotic static of a reality warper.

 

He took a step forward, leaving the Backrooms behind, and stepped into the swirling maelstrom to fight his way back to Earth.

 

 

 

The passage between realities was not a physical tunnel; it was an agonizing meat-grinder of sensory information.

 

When Izuku Midoriya stepped through the spatial tear in his newly forged cherry blossom grove, he didn't walk from point A to point B. He was dragged through the underlying source code of the multiverse. For an eternity that lasted only a fraction of a second, he saw the birth and death of stars, heard the absolute silence of dead dimensions, and felt the crushing weight of infinite, stacked probabilities pressing against his skin.

 

He held his form together through sheer willpower, wrapping himself in a cocoon of One For All’s stockpiled glitch energy. The green, cyan, and magenta static formed a protective halo around him, deflecting the chaotic radiation of the void.

 

With a deafening, vacuum-sealed pop, Izuku was forcefully spat out the other side.

 

He hit the ground in a crouch, his iron soles scraping violently against rough concrete. He skidded for a few feet before digging his fingers into the floor to arrest his momentum. He stayed low for a moment, his chest heaving, his breath pluming in front of his face in a cloud of white vapor.

 

The air here was freezing. It smelled of wet cement, rust, and ozone.

 

Izuku stood up slowly, the static aura around his body retracting back under his skin, though his emerald eyes continued to pulse with a faint, digital ring. He took stock of his surroundings.

 

He was standing in a tunnel.

 

It was a subterranean, cylindrical passage made of dull, grey concrete. It resembled a massive, brutalist sewer system or a forgotten subway line, but without any tracks or water. Bare incandescent bulbs hung from the curved ceiling by thin, frayed wires, casting pools of weak, sickly yellow light every twenty feet. The spaces between the lights were draped in heavy shadows.

 

But the most defining feature of the tunnel was the doors.

 

Embedded into the curved concrete walls on either side, spaced at perfectly regular intervals, were doors. Millions of them. They stretched down the tunnel in both directions until the curvature of the space and the gloom swallowed them. And none of the doors matched.

 

To his left was a heavy, rusted iron bulkhead with a nautical wheel. Next to it was a flimsy, wooden screen door that looked like it belonged on a suburban porch. Across the hall was a pristine, white sterile hospital door with a reinforced glass window, completely black on the other side.

 

This was the Hub. The crossroads of the Backrooms. The central terminal connecting the infinite, chaotic levels of the liminal space.

 

"I'm close," Izuku whispered. The acoustics of the concrete tunnel made his voice echo endlessly, bouncing off the millions of doors.

 

He knew one of these doors led back to his reality. Back to Musutafu. Back to his mother, his friends, and the fight against the spatial-villain Fracture. But opening them at random was suicide. Behind some doors were other levels of the Backrooms. Behind others were dead dimensions, vacuums of space, or realities governed by physics that would instantly unravel a human body.

 

He needed a compass.

 

Izuku closed his eyes. He didn't rely on sight or sound; he relied on the evolution of his Quirk. He extended his right hand, palm open, and gently tapped the frequency of One For All.

 

Hummm.

 

A subtle vibration rippled through the air, like a tuning fork struck in a quiet room. Izuku was broadcasting a sub-spatial ping, searching for the specific emotional and physical resonance of his native Earth. He was looking for the frequency of Quirks. The fiery, explosive energy of Bakugo. The weightless, floating gravity of Uraraka. The warm, radiant legacy of All Might.

 

He walked slowly down the center of the tunnel, his hand outstretched, feeling the invisible currents radiating from the doors.

 

He passed a door made of solid, unpolished obsidian. It radiated a feeling of absolute, crushing pressure. Ocean dimension. Millions of tons of water. He kept walking.

 

He passed a door covered in peeling, floral wallpaper. It whispered with the sound of a thousand overlapping, synthetic giggles. Level Fun. Or a Partygoer hive. He ignored it.

 

He walked for what felt like hours, though time in the Hub was completely stagnant. He passed thousands of doors. The mental strain of processing the ambient data from so many realities was immense. His nose began to bleed, a single drop of crimson trailing over his lip. He wiped it away, noticing that the blood flickered slightly with static before settling into liquid.

 

Then, he felt it.

 

It was faint, almost completely drowned out by the chaotic noise of the Backrooms, but it was there. A spike of localized, structured energy. It felt like home.

 

Izuku snapped his head to the right. He sprinted down the tunnel, his boots slamming against the concrete, the sound echoing like a drumline. He skidded to a halt in front of a cluster of doors.

 

He reached out and placed his hand on a heavy, steel security door. It was cold to the touch, and painted in a faded, familiar color: UA High School blue. In the center, barely visible under a layer of grime and rust, was the stencil of the UA logo.

 

A surge of pure, unadulterated relief washed over him. The tension that had kept him rigidly composed for an eternity finally cracked. A genuine, wavering smile broke across his face.

 

"Found you," he breathed, gripping the heavy iron handle.

 

Suddenly, the concrete beneath his feet violently shuddered.

 

Izuku stumbled backward, releasing the handle. The solitary incandescent bulb above him flared to a blinding, scorching white, and then exploded in a shower of sparks. Down the length of the endless tunnel, every single lightbulb shattered in a cascading wave of destruction.

 

The Hub was plunged into near absolute darkness, illuminated only by the emergency red lights that abruptly flared to life from hidden recesses in the ceiling.

 

A deafening, mechanical siren began to blare. It didn't sound like a fire alarm; it sounded like a massive, corrupted hard drive grinding against its reader head. It was the sound of a system detecting a fatal error.

 

The Backrooms had realized what Izuku was doing.

 

Izuku Midoriya was not just a lost wanderer anymore. By surviving, adapting, and ultimately overwriting Level Fun into Level Midoriya, he had become a virus. He had introduced foreign, unauthorized code into the liminal ecosystem. And now, the virus was trying to breach the firewall and escape.

 

The system was initiating an anti-virus protocol.

 

The concrete walls of the Hub began to warp and bubble like boiling wax. The doors surrounding the UA door violently shifted, moving away as if repelled by a magnet, isolating Izuku’s exit in a wide expanse of stretching concrete.

 

"No you don't!" Izuku yelled. He lunged for the UA door.

 

Before his fingers could touch the handle, the floor erupted.

 

It wasn't an explosion of stone. The concrete simply unraveled into a geometric wireframe, revealing a bottomless pit of television static. From the static, a colossal mass of shifting, chaotic matter rose up, cutting Izuku off from the door.

 

Izuku flipped backward, landing thirty feet away, his cyan and magenta aura flaring to life, casting harsh, colorful shadows against the red emergency lights.

 

He looked up at the entity blocking his path, and even his god-like detachment faltered for a second.

 

This was not a Hound. This was not a Smiler or a Partygoer. This was a Guardian. An apex manifestation of the Backrooms' immune system.

 

It had no defined shape. It was a Lovecraftian nightmare roughly four stories tall, composed entirely of shifting, intersecting liminal spaces. One of its "arms" was a twisted, non-Euclidean staircase that looped infinitely into itself. Its torso was a cluster of acoustic ceiling tiles, buzzing fluorescent lights, and peeling yellow wallpaper, all folding and unfolding like a hyper-dimensional tesseract. Where its head should have been, there was only a massive, swirling sphere of absolute, light-devouring void, surrounded by a halo of violent red static.

 

It didn't roar. It didn't make a sound. Its mere presence was so heavy that the gravity in the tunnel began to curve around it.

 

Izuku could feel his own skin beginning to glitch, the ambient reality-warping of the Guardian attempting to delete his physical form.

 

"You're not keeping me here," Izuku said. His voice was no longer that of a frightened teenager. It was layered with the terrifying, metallic resonance of his stockpiled power. "I'm going home."

 

He didn't wait for the entity to strike.

 

Izuku planted his feet and unleashed One For All at 50%. The green lightning mixed with the cyan static, turning him into a blur of chromatic energy. He launched himself forward, rearing his right arm back.

 

“Texas... SMASH!”

 

He threw the punch. The sheer force of the shockwave compressed the air in the tunnel into a solid projectile, firing toward the Guardian’s center of mass with enough power to level a skyscraper.

 

The shockwave struck the entity’s torso of yellow wallpaper and acoustic tiles.

 

But it didn't shatter. The moment the kinetic energy made contact, a door on the Guardian’s chest swung open. The inside of the door led to a pocket dimension of infinite empty space. The door simply swallowed the shockwave, absorbing the kinetic energy without a sound, and snapped shut.

 

‘It nullified the physics,’ Izuku realized instantly.

 

Before Izuku could adjust his trajectory, the Guardian retaliated. The entity didn't move its massive, cumbersome body. It simply bent space.

 

The Guardian’s staircase-arm, which was fifty feet away, suddenly occupied the exact space Izuku was flying through. It didn't travel the distance; the Guardian deleted the fifty feet of empty air between them.

 

Izuku slammed face-first into the concrete steps of the arm with bone-shattering force.

 

He was instantly caught in a fractal trap. Gravity inverted. The staircase pulled him downward, but "down" was constantly shifting. He fell up a flight of stairs, tumbled sideways through a hallway that suddenly sprouted from the steps, and was violently thrown out through a trapdoor, plummeting toward the floor of the Hub at terminal velocity.

 

Izuku twisted in mid-air. “Float!”

 

He caught himself ten feet above the concrete, hovering in the red emergency light. He wiped a streak of static-blood from his cheek.

 

"Physical attacks are useless. It just routes the kinetic energy into a dead level," Izuku muttered, his mind working a million miles a minute. "If I want to beat a glitch, I have to fight like a glitch."

 

The Guardian’s void-sphere "head" pulsed violently. The red static halo expanded, and suddenly, the concrete floor beneath Izuku turned into a liquid ocean of black mold and rot. Tendrils of heavy, dark matter shot upward, seeking to drag him into the depths.

 

Izuku didn't fly away. He dropped his physical fighting stance entirely.

 

He raised his hands as if gripping an invisible steering wheel. He flooded his entire nervous system with the localized reality-warping energy he had harvested from Level Midoriya. His eyes became blinding rings of digital light.

 

“Override Command: Architecture,” Izuku stated.

 

He forcefully twisted his hands to the right.

 

With a deafening, agonizing groan of bending reality, the entire cylindrical tunnel of the Hub rotated ninety degrees. The floor became the wall. The wall became the ceiling.

 

The Guardian, caught off guard by the sudden re-coding of the level's geometry, stumbled, its massive shifting bulk sliding down the newly formed wall. The liquid rot it had spawned poured harmlessly away into a nearby ventilation shaft.

 

Izuku walked effortlessly along what used to be the wall, gravity anchoring to the soles of his boots because he commanded it to.

 

He raised his right arm, pointing directly at the Guardian.

 

He didn't summon Blackwhip as a physical tether. He summoned it as a conceptual lasso. A stream of pure, screaming digital code erupted from his palm. The chromatic static lashed out and wrapped around the Guardian’s staircase-arm.

 

"You like deleting space?" Izuku yelled. "Let's see how you handle an isolation protocol!"

 

Izuku yanked his arm back. He wasn't pulling the creature; he was selecting its code and dragging it to a different directory.

 

He forcefully isolated the spatial coordinates of the Guardian’s arm, severing its connection to the main body. The air ripped with the sound of tearing metal and static. The massive, infinite staircase was brutally amputated from the Guardian. Izuku swung his arm, throwing the amputated geometry down the endless tunnel of the Hub, where it crashed and dissolved into a pile of harmless, non-anomalous concrete rubble.

 

The Guardian shuddered, an aura of violent red error-messages flashing across its form. It was furious.

 

The void-sphere at the top of its mass expanded rapidly. It stopped relying on liminal space and tapped directly into the destructive void of the Backrooms. A beam of absolute, light-devouring nothingness fired from the sphere, carving a path of pure erasure straight toward Izuku. Where the beam touched the concrete, the tunnel ceased to exist, leaving only a white, wireframe void behind.

 

Izuku didn't dodge. If he dodged, the beam would strike the UA door behind him, deleting his only way home.

 

He flew forward, directly into the path of the void beam.

 

He crossed his arms in an 'X' over his chest. “One For All: Reality Cowl—One Hundred Percent!”

 

Izuku didn't create a shield. He asserted his own existence so violently that the void could not consume him. He became an anchor point of absolute, undeniable reality.

 

The beam of nothingness struck him. The collision was completely silent, but the visual shockwave was apocalyptic. The red light of the Hub was blasted away, replaced by a blinding, strobing flash of clashing code. The void tried to unwrite Izuku's atoms; Izuku's Quirk forcefully wrote them back, frame by frame, in real-time.

 

His UA costume disintegrated into digital ash. The skin on his arms tore away, revealing not muscle and bone, but glowing, solid light—the pure essence of One For All. He was holding back a wave of erasure with his raw soul.

 

‘I am Izuku Midoriya!’ he screamed in his mind, his physical voice lost in the void. ‘I have a mother waiting for me! I have friends who need me! I am a hero! You are just empty space, and I refuse to be empty!’

 

He pushed forward. Step by agonizing step, he walked up the beam of nothingness, forcing the void back toward the Guardian.

 

The Guardian’s shifting architecture began to panic, thrashing wildly. It tried to spawn more limbs, tried to shift the geometry again, but Izuku’s localized field of absolute reality paralyzed it. Izuku was locking the physics of the Hub in place.

 

He reached the end of the beam, standing mere feet away from the swirling, red-haloed void sphere.

 

Izuku pulled his right fist back.

 

He wasn't going to use kinetic energy. He wasn't going to use a simple code override. He was going to use the core of One For All—the stockpiled wills of the past users, combined with the god-like architectural power he had forged in the Backrooms. He was going to inject the Guardian with something the Backrooms had never experienced.

 

Order. Logic. Empathy. Humanity.

 

He extended his thumb and middle finger, preparing for a flick, but folded it into a full-force punch.

 

“DELAWARE DETROIT SMASH: REALITY ANCHOR!”

 

Izuku drove his fist directly into the center of the void-sphere.

 

There was no explosion. There was no concussive shockwave.

 

Instead, a pulse of brilliant, pure, golden sunlight erupted from Izuku’s knuckles. It was the light of the real world. The light of a sunny afternoon at UA High. The light of All Might’s smile.

 

The golden light injected directly into the Guardian’s code. The reaction was instantaneous and cataclysmic.

 

The Backrooms was a system built on chaos, fear, and non-Euclidean nonsense. It could not process absolute, positive order. The golden light spread through the Guardian like a cure through a diseased bloodstream.

 

The shifting, maddening architecture of its body locked into place. The infinite staircases flattened. The yellow wallpaper burned away. The red static was overwritten by a calm, steady green glow.

 

The massive, Lovecraftian horror let out a single, final sound—not a roar of pain, but a long, mechanical sigh, like a computer powering down.

 

In a matter of seconds, the entire Guardian was transmuted. It turned from a creature of void and liminal horror into a colossal, beautifully carved statue of normal, solid marble. It was a monument to the defeat of the glitch.

 

Izuku floated backward, dropping out of Reality Cowl. His skin knit back together, his breath coming in heavy, exhausted gasps.

 

He looked at the marble statue. He reached out and tapped it with a single finger.

 

Tink.

 

The statue fractured. A million hairline cracks spread across the marble. And then, it shattered. The Guardian collapsed into millions of harmless, perfectly normal glass marbles that rained down onto the concrete floor with a deafening, musical clatter.

 

The Hub fell perfectly silent.

 

The red emergency lights faded out, and one by one, the normal incandescent bulbs along the ceiling flickered back to life, casting their weak yellow light over the sea of glass marbles.

 

The Backrooms had thrown its ultimate defense at him, and he had broken it. The system was temporarily stunned. The firewall was down.

 

Izuku landed heavily on the concrete. The god-like detachment, the cold, algorithmic processing power that had possessed him, began to recede like a retreating tide. The cyan and magenta rings in his eyes faded back to their natural, vibrant emerald green.

 

The sheer physical and mental toll of what he had just done hit him like a freight train. His knees buckled, and he fell to the floor, coughing violently. His muscles screamed in agony, mimicking the feeling of 100% full-body blowback, even though the damage was entirely spiritual.

 

"I did it," he wheezed, staring at the floor. "I survived."

 

He forced himself back to his feet, his legs shaking violently. He turned around.

 

There, standing alone in the restored concrete wall, untouched by the devastation, was the steel door with the UA logo.

 

Izuku limped toward it, his boots crunching over the glass marbles. Every step felt like lifting a mountain, but the magnetic pull of home dragged him forward.

 

He reached the door. He placed his bare, bruised hand against the cold steel. He could feel the vibration again. The chaotic, beautiful, living hum of his universe. He could almost hear the sirens in Musutafu. He could almost smell the smoke of Bakugo’s explosions.

 

Izuku gripped the heavy iron handle.

 

He paused, looking back over his shoulder down the infinite, echoing tunnel of the Hub. The Backrooms stretched out forever, a prison of endless yellow rooms, dark pipes, and sadistic entities. It had tried to consume him, to break his mind, to turn him into a monster.

 

Instead, it had forged him into something transcendent. He was leaving as the Architect.

 

"Goodbye," Izuku whispered to the void.

 

He turned the handle. The heavy locking mechanism clicked with a satisfying, real-world thud.

 

Izuku pushed the door open, stepping out of the fluorescent gloom and into a blinding flash of natural, chaotic sunlight.

 

 

 

 

Time is a subjective measurement, anchored entirely by the gravity of the reality in which it is observed.

 

For Izuku Midoriya, he had lived an eternity. He had walked through infinite yellow corridors, battled eldritch abominations in the suffocating dark, mapped the architecture of non-Euclidean voids, and fundamentally rewritten the source code of his own soul. He had aged in ways the human body was never designed to endure, his mind expanded to process the raw, algorithmic data of the multiverse.

 

But on Earth, in the commercial district of Musutafu, the digital clock on a shattered bank marquee ticked over from 3:14 PM to 3:15 PM.

 

Exactly four minutes and fifty-two seconds had passed since Izuku Midoriya was swallowed by a concrete wall.

 

For Katsuki Bakugo, those four minutes and fifty-two seconds had been a waking nightmare of fire, blood, and screaming adrenaline.

 

"Keep him boxed in! Don't let him drop his hands!" Bakugo roared, his voice cracking from the ash and smoke clogging his throat.

 

He fired off a massive, consecutive string of Stun Grenades, the blinding flashes of light and deafening concussive blasts illuminating the ruined plaza. His arms were screaming in agony, the muscles tearing from the recoil of overusing his Quirk, but he couldn't stop. If he stopped, they died.

 

Ten yards away, Shoto Todoroki was on one knee, gasping for air. The entire right side of his body was covered in a thick layer of frost, his core temperature dropping to dangerous levels. He had created a massive, towering glacier to shield a group of trapped civilians, but the villain, Fracture, had simply carved a spatial anomaly right through the center of the ice, leaving perfectly smooth, impossible voids in the frozen structure.

 

"It's no use, Bakugo," Todoroki panted, forcing his left side to ignite in a desperate attempt to regulate his body heat. "His activation speed is increasing. The Trigger in his system is making his Quirk mutate further. He's not even aiming anymore."

 

"I don't give a damn!" Bakugo snarled, propelling himself sideways with a localized explosion as a jagged, violet tear in space ripped through the asphalt exactly where he had been standing. The streetlamp behind him was cleanly bisected, the top half teleporting three blocks away while the bottom half crashed to the ground.

 

Fracture was no longer a man; he was a conduit of chaotic energy. The petty thief’s eyes were completely rolled back into his head, black veins bulging against his temples from the lethal overdose of the Trigger drug. He was screaming uncontrollably, throwing his hands out in wild, spasming arcs.

 

With every movement, reality shattered.

 

"Aizawa-sensei! Can you get an angle on him?!" Tenya Iida shouted through the comms, his voice laced with uncharacteristic panic as he sprinted in a blur of exhaust fumes, carrying an unconscious police officer out of the danger zone.

 

"I can't lock on!" Shota Aizawa’s frustrated voice cracked back. The underground hero was perched atop a half-crumbled billboard, his capture scarf whipping violently in the wind. "The spatial distortions are bending the light around him! I can't establish a direct line of sight to erase his Quirk! If I get any closer, I'll be pulled into a void!"

 

‘Where the hell is the nerd?’ Bakugo thought frantically, landing heavily on the roof of an overturned sedan. ‘He took a direct hit from that spatial wave. Did he get teleported? Did he get crushed? No. Deku doesn't just die. He's out there. He has to be.’

 

But the grim reality of the situation was settling over the battlefield. The heroes were losing.

 

Suddenly, Fracture let out a blood-curdling shriek. The Trigger in his blood reached its absolute peak, pushing his Quirk beyond its breaking point. His body began to levitate slightly off the ground, lifted by the sheer gravitational anomaly he was generating.

 

A massive, pulsing sphere of violet energy formed between his outstretched hands. It wasn't a tear. It was a localized black hole of spatial distortion. It was expanding rapidly, the gravitational pull ripping the shattered asphalt, glass, and cars into its center, where they simply ceased to exist.

 

"He's going critical!" Aizawa yelled. "Fall back! Everyone, fall back immediately! It's going to consume the whole block!"

 

Bakugo turned to run, but his eyes caught a flash of pink beneath the rubble of the bank's entrance.

 

It was Ochaco Uraraka. She had pushed herself past her weight limit floating debris off the civilians Midoriya had saved five minutes ago. She was on her hands and knees, violently dry-heaving, completely immobilized by her Quirk's nausea backlash.

 

And she was directly in the path of the expanding spatial anomaly.

 

"Round Face!" Bakugo screamed.

 

He didn't think. He didn't calculate. He ignited his palms, preparing to launch himself directly into the gravitational pull to blast her out of the way, knowing full well he wouldn't have the momentum to escape himself.

 

Fracture unleashed the sphere.

 

A massive, silent wave of violet distortion rolled across the plaza. It moved with terrifying speed, warping the air, tearing the molecular bonds of everything in its path. It was a tsunami of absolute destruction, seconds away from hitting Uraraka and Bakugo.

 

Bakugo threw his hands out, bracing for the end.

 

And then, the universe blinked.

 

 

 

It wasn't a sound. It was an absence of sound.

 

For a single, agonizing microsecond, the roaring fires, the sirens, the screaming villain, and the collapsing buildings were completely muted, replaced by the deafening, electrical drone of a fluorescent light bulb.

 

The air itself ten feet in front of Uraraka cracked open.

 

It didn't tear like Fracture’s violet portals. It shattered like a pane of thick glass, revealing a blinding, pure white wireframe of nothingness behind the fabric of the world.

 

From the tear, a heavy, steel door swung outward into the plaza.

 

A figure stepped out.

 

The heavy steel door slammed shut behind him and instantly dissolved into digital static, vanishing into the air.

 

Katsuki Bakugo froze, his explosions dying in his palms. Ochaco Uraraka looked up, her tear-filled eyes widening in absolute disbelief. Aizawa stopped mid-swing on his capture tape.

 

It was Izuku Midoriya.

 

But it wasn't the boy they knew.

 

He stood up straight, his posture completely devoid of his usual nervous tension. He looked taller, though his physical height hadn't changed. His hero costume was completely annihilated—reduced to tattered, ash-stained pants, his iron soles scraped down to the bare metal, and the shredded remnants of his shirt hanging from his shoulders. His arms were heavily scarred, not just with the old surgical scars of his Quirk, but with bizarre, geometric burns that looked like circuit board pathways etched into his flesh.

 

But it was the aura surrounding him that paralyzed the battlefield.

 

Izuku was bathed in a terrifying, ethereal glow. Faint, overlapping rings of cyan, magenta, and green static pulsed beneath his skin. The air around him didn't just heat up; it warped, bowing to his physical presence. The debris falling from the sky around him—chunks of concrete and glass—hit an invisible, ten-foot radius around him and simply stopped, freezing in mid-air, ignoring the laws of gravity completely.

 

Izuku slowly opened his eyes. They were not normal. The irises were glowing with an intense, digital emerald light, and the pupils were expanding and contracting like the aperture of a camera lens processing infinite data.

 

The chaotic, deafening noise of Musutafu hit his eardrums. It was overwhelming. The screaming, the sirens, the wind.

 

‘Too loud,’ Izuku’s mind processed with algorithmic coldness. ‘Audio levels exceed optimal parameters. Adjusting.’

 

He didn't cover his ears. He simply commanded the soundwaves to dampen. Within a hundred-yard radius, the decibel level of the world dropped to a soft, manageable murmur.

 

He looked forward. The violet tsunami of spatial distortion from Fracture was bearing down on him, only yards away, threatening to annihilate him, Uraraka, and Bakugo.

 

Izuku didn't drop into a fighting stance. He didn't summon the green lightning of One For All. He didn't brace for impact.

 

He looked at the apocalyptic wave of spatial energy and sighed. A soft, weary sigh of a god looking at a child’s messy finger painting.

 

‘Sloppy code,’ Izuku thought. ‘Unstable algorithmic generation. Poor structural integrity.’

 

He raised his right hand. He didn't ball it into a fist. He gently pressed his thumb against his middle finger.

 

Izuku snapped his fingers.

 

The acoustic sound of the snap was impossible. It wasn't loud, but it echoed directly inside the skulls of everyone present. It sounded like a massive, heavy lock tumbling into place.

 

The moment his fingers sparked, the reality-warping energy of the Backrooms—the power he had stockpiled, refined, and mastered as the Architect of Level Midoriya—was injected directly into Earth's atmosphere.

 

The violent, violet tsunami of spatial distortion hit Izuku’s localized field of absolute reality.

 

It didn't explode. It didn't bounce off.

 

It transmuted.

 

The lethal, reality-tearing energy instantly fragmented into millions of harmless, iridescent spheres. The violet anomaly was completely overwritten.

 

Soap bubbles.

 

Millions upon millions of shimmering, perfectly spherical soap bubbles cascaded over Izuku, washing gently over a stunned Uraraka and a completely paralyzed Bakugo. They floated peacefully into the sky, catching the sunlight, popping with tiny, wet pinks against the ruined asphalt.

 

The catastrophic attack was entirely gone.

 

Silence fell over the plaza. Not a magical silence, but a genuine, terrified silence of awe. Even the fires seemed to stop crackling.

 

Fracture, floating in the air, his eyes wide with drug-fueled madness, stopped screaming. He looked down at his hands, then up at the boy surrounded by floating concrete and soap bubbles.

 

"What..." Fracture gasped, his voice trembling. "What did you do? Where did my space go?!"

 

Izuku didn't answer. He took a step forward.

 

He didn't walk normally. When his foot lifted, the space between him and Fracture seemed to fold. A distance of fifty yards was compressed into three steps.

 

Fracture panicked. The villain screamed, drawing a heavy, metallic support-item blaster from a holster on his hip. He aimed it directly at Izuku’s chest and pulled the trigger. A massive blast of concentrated plasma erupted from the barrel.

 

Izuku didn't even blink. He just kept walking.

 

As the plasma beam struck the ten-foot radius around Izuku, it didn't burn him. The energy’s molecular state was forcefully re-coded by Izuku’s presence. The searing hot plasma instantly cooled and solidified into a stream of fine, white sand, cascading harmlessly onto the street in front of Izuku’s boots.

 

Fracture shrieked in absolute terror. He threw the gun away and frantically tried to open another spatial portal, throwing his glowing hands toward Izuku.

 

Izuku stepped directly into the villain’s personal space.

 

He looked up at Fracture. For a fleeting second, the human facade of Izuku Midoriya slipped. The traumatic, god-like horror of the Backrooms bled into the real world. His eyes flared with violent, television static. The shadows behind Izuku seemed to elongate, stretching into infinite, twisting, yellow hallways that weren't really there.

 

Fracture looked into Izuku’s eyes, and his mind broke. The villain saw the infinite void. He saw a realm where he was less than a speck of dust. He saw the Guardian shattered into glass.

 

Fracture’s spatial Quirk instantly deactivated, sputtering out like a dying candle. The villain fell to his knees on the asphalt, sobbing hysterically, unable to bear the sheer weight of the existential dread radiating off the boy.

 

Izuku looked down at the weeping, hyperventilating man. The cold, algorithmic detachment of the Administrator analyzed the threat.

 

‘Target: Hostile. Status: Mentally unstable. Chemical imbalance detected in the prefrontal cortex and adrenal glands. Solution: Recode neurochemistry.’

 

Izuku reached out with his right hand. He didn't throw a punch. He gently, almost tenderly, pressed his index and middle fingers against Fracture’s forehead.

 

A tiny, microscopic spark of cyan light passed from Izuku’s fingertips through the villain’s skull.

 

Izuku didn't use force. He used his reality-warping to perform localized biological editing. In a fraction of a millisecond, he lowered Fracture’s adrenaline levels to zero, flooded his brain with melatonin and serotonin, and gently severed the chemical pathways of the Trigger drug.

 

Fracture’s sobbing stopped mid-breath. His eyes rolled back, his body going completely limp. He fell forward, snoring softly, plunged into a deep, unbreakable, peaceful sleep.

 

The battle was over.

 

Izuku stood over the unconscious villain. The debris that had been floating around him gently settled to the ground as he released his hold on the localized gravity.

 

The silence in the plaza was suffocating.

 

Slowly, agonizingly, Katsuki Bakugo lowered his hands. His crimson eyes were wide, the pupils blown out in shock. He looked at the soap bubbles resting on the ground. He looked at the pile of sand. He looked at the god-like, glowing entity standing where his childhood rival used to be.

 

"Deku...?" Bakugo whispered, the nickname sounding hollow and unsure in the vast silence.

 

Izuku didn't turn around immediately. He was struggling.

 

The transition back to reality was tearing at his mind. The Backrooms had required him to abandon his humanity to survive. It required him to view the universe as raw math, to feel no fear, to hold dominion over physics. Standing here, in the sunlight, the urge to simply rewrite the entire ruined city—to instantly fix the buildings, heal the wounded, and wipe the trauma away with a snap of his fingers—was overwhelmingly strong. He had the power to do it. He could be a god.

 

But as the cyan and magenta static flared in his vision, he heard a sound.

 

Sniff.

 

He turned his head. Ochaco Uraraka was looking at him. She was trembling, tears streaming down her dirty cheeks. She wasn't looking at him with awe. She was looking at him with terror.

 

She didn't recognize him.

 

That look, more than anything else, pierced through the cold, algorithmic armor he had built in the Backrooms. It hit the core of Izuku Midoriya—the boy who just wanted to save people with a smile.

 

‘I am not a god,’ Izuku thought desperately, violently pushing the Administrator persona back into the depths of his mind. ‘I am not the Backrooms. I am a hero.’

 

Izuku closed his eyes and took a deep, shuddering breath of normal, polluted, beautiful city air.

 

He forced the energy down. He pulled the reality-warping static back into the core of One For All, locking the door on the void. The cyan and magenta rings in his eyes slowly faded, dissolving back into his warm, human emerald green. The faint glow of his skin dimmed, and the terrifying, heavy pressure he exerted on the environment vanished completely.

 

He was just a boy in a shredded hero costume again.

 

Izuku turned to face his classmates. His legs suddenly felt incredibly heavy. The adrenaline of survival was crashing, replaced by a profound, bone-deep exhaustion.

 

He looked at Uraraka. He looked at Bakugo, who was staring at him like he was a ghost. He saw Aizawa dropping down from the billboard, his scarf unraveling, his tired eyes filled with a mixture of immense relief and profound suspicion.

 

Izuku’s lips trembled. The corners of his mouth twitched upward. He forced the stiff muscles of his face to remember how to convey warmth.

 

He smiled. It wasn't the manic, carved smile of a Partygoer. It wasn't the hollow, manufactured smile of the cargo-cult All Might he had created in Level 6. It was genuine, soft, and heartbreakingly human.

 

"I'm back," Izuku said, his voice cracking, devoid of the metallic, overlapping echoes. "I'm sorry I worried you."

 

Uraraka let out a sob, scrambling to her feet and throwing her arms around him. The impact nearly knocked Izuku over. He winced, his bruised ribs protesting, but he slowly raised his arms and hugged her back, burying his face in her shoulder. She felt warm. She felt real.

 

Bakugo stalked forward, stopping a few feet away. He looked at the sleeping villain, then back at Izuku.

 

"What... what the hell did you just do, you damn nerd?" Bakugo demanded, his voice shaking slightly despite his aggressive tone. "Where did you go? It's been five minutes! What was that?!"

 

Izuku looked over Uraraka’s shoulder at Bakugo. He thought of the infinite yellow halls. He thought of the endless years of isolation, the Almond Water, the crushing darkness of Level 6, and the shattering of the Guardian.

 

"Five minutes," Izuku whispered, a single tear escaping his eye, tracking through the soot on his cheek. "Yeah. It... it was a really long five minutes, Kacchan."

 

Aizawa approached, his hand resting cautiously on his capture scarf. He looked at the perfect, geometric burns on Izuku’s arms. He looked at the soap bubbles. He had seen powerful Quirks in his life, but he recognized an anomaly when he saw one. He knew, inherently, that the boy standing in front of him had just done something that broke the fundamental laws of the universe.

 

"Midoriya," Aizawa said softly, his tone unusually gentle. "Are you... are you still you?"

 

Izuku pulled back from Uraraka gently. He looked his teacher in the eye. He felt the terrifying, infinite power of the Backrooms humming quietly in the depths of his soul, a chained beast waiting to be called upon. He knew he could never go back to being just a boy who punched hard. He was forever changed.

 

But he nodded.

 

"I am, Sensei," Izuku said, his voice steady. "I'm still a hero."

 

Aizawa studied him for a long moment, then let out a long breath, releasing his scarf. "Good. Because you have one hell of a debriefing ahead of you."

 

 

 

Two Days Later - UA High School, Class 1-A Dormitories

 

The official story fed to the media was that Izuku Midoriya had experienced a secondary Quirk Awakening during the fight, allowing him to neutralize Fracture’s spatial anomalies with a localized energy pulse. It was a neat, digestible lie that prevented mass panic.

 

The reality behind closed doors was much messier.

 

In the medical wing of UA, Recovery Girl had nearly suffered a heart attack while examining him. When she tried to draw his blood, the needle phased through his skin in a burst of television static. His internal biology was fundamentally altered. His cells were constantly regenerating and shifting, maintaining an impossible state of perfect equilibrium. His heart didn't just beat; it pulsed with a faint, electrical hum.

 

When questioned by Aizawa, All Might, and Detective Tsukauchi, Izuku had tried to explain. He told them about the clipping. About the yellow rooms, the hum of the lights, the entities. He told them he had been trapped there for years.

 

Tsukauchi’s lie detector Quirk had nearly short-circuited. It registered Izuku’s statements as absolute truth, yet impossible.

 

All Might had wept, holding Izuku’s hand, realizing the boy he had passed One For All to had endured a hell he couldn't even conceptualize. But Izuku had simply smiled and reassured him. He didn't feel traumatized in the way they expected. He felt old. He felt calm.

 

They realized, with a mixture of awe and quiet terror, that Izuku Midoriya was no longer bound by Quirks. He had evolved into a cosmic failsafe.

 

Now, back in his dorm room, the silence of the night was heavy.

 

Izuku sat cross-legged on the floor, wearing a loose t-shirt and sweatpants. The room was dark, illuminated only by the moonlight filtering through the window. It was the real moon. He had spent hours just staring at it, making sure it didn't glitch or repeat its pattern.

 

He looked around his room. It was exactly as he had left it. It was exactly as he had recreated it in the void of Level 6. But this time, the All Might posters were real. The books on his desk had words in them.

 

He breathed in the scent of normal, fresh air, devoid of the smell of damp carpet.

 

But the peace was interrupted.

 

Bzzzt.

 

Izuku’s eyes snapped open. The sound was incredibly faint, but to his hypersensitive ears, it was deafening. It was the sound of a fluorescent light buzzing.

 

He stood up silently and walked over to the wall near his closet.

 

There, near the baseboard, the plaster was shifting. A small crack had formed in the drywall. But behind the crack, there was no insulation or wood. There was a sickly, glowing yellow light. The faint smell of moist, old carpet wafted into the room.

 

The Backrooms.

 

It was a naturally occurring spatial tear. The universe was flawed. Glitches happened. Before, a tear like this might have swallowed an unsuspecting civilian, dropping them into the eternal hell of Level 0. The Backrooms were always there, lurking just behind the wallpaper of reality, waiting for a clip.

 

Izuku didn't panic. He didn't activate One For All’s full power.

 

He knelt down in front of the crack. He looked into the yellow light. He could feel the vast, infinite emptiness on the other side. He could feel the entities shifting in the dark, miles away.

 

But they didn't reach for him. As Izuku looked into the void, the void recoiled. The yellow light flickered in fear. The Backrooms remembered him. It remembered the boy who had conquered Level Fun, shattered its Guardian, and rewritten its laws.

 

Izuku raised his hand. His fingertips glowed with a soft, warm, golden light.

 

He gently pressed his hand flat against the cracked drywall.

 

"Not here," Izuku whispered softly. "This world is protected."

 

He channeled a fraction of his power. He didn't use it to destroy. He used it to heal.

 

With a smooth, seamless motion, he dragged his hand over the crack. The reality-warping energy welded the fabric of space back together. The sickly yellow light was snuffed out. The smell of damp carpet vanished. The drywall became perfectly smooth and solid, devoid of even a scratch.

 

Izuku pulled his hand back and stood up in the quiet dark of his room.

 

He looked out the window at the sleeping city of Musutafu. He knew there would be more villains. He knew Shigaraki, All For One, and countless other threats were out there. But for the first time in his life, Izuku wasn't afraid.

 

He was no longer just preparing to be the Symbol of Peace.

 

A Symbol was something people looked up to for hope. A Symbol fought the villains on the surface.

 

But Izuku Midoriya was something deeper now. He was the one who held the walls of the world together. He was the barrier between the light of reality and the crushing infinity of the glitch.

 

He turned away from the wall and climbed into bed, pulling the covers up. He closed his eyes, and for the first time in what felt like a lifetime, he didn't hear the hum of fluorescent lights.

 

He just heard the quiet, beautiful hum of home.

 

And the Anchor of Reality finally went to sleep.
