What If Deku Was Transported To The Kingdom Of Lugunica

 The rain in Japan tasted of ash and copper. 

Izuku Midoriya, the ninth wielder of One For All, vaulted over the shattered remnants of a concrete overpass. His breath came in ragged, burning gasps, cutting through the heavy deluge that washed over the ruined city. His yellow cape—Gran Torino’s cape—clung to his shoulders like a lead weight, soaked with mud and the blood of a dozen minor skirmishes. Beneath his tattered, dark green cowl, his emerald eyes darted frantically, analyzing every shadow, every shift in the debris.

Danger Sense thrummed in his skull, a dull, ceaseless ache that had long since become his baseline reality. The Paranormal Liberation Front was relentless. Tartarus escapees roamed the streets. Shigaraki was out there, resting, growing stronger. 

I have to keep moving, Izuku thought, his scarred hands tightening into fists. Green lightning—the physical manifestation of the immense, borrowed power coursing through his veins—crackled over his skin, illuminating the dark alleyway he had ducked into. If I stop, they catch up. If they catch up, people get hurt. I have to—

The thought was violently severed. 

A spatial distortion, tearing through the air with a sound like ripping silk, bloomed directly in his path. It wasn't one of Kurogiri’s swirling purple warp gates, nor was it the grotesque, muddy sludge of All For One. This anomaly was jagged, a fracture in reality itself that bled blinding, prismatic light. 

Izuku dug his iron-soled boots into the asphalt, attempting to reverse his momentum. Fa Jin flared in his legs, ready to launch him backward, but the gravitational pull of the rift was absolute. It didn't just pull his body; it felt as though it was dragging his very soul. 

He didn't even have time to scream. The alleyway, the rain, the ash, and the ruined world of heroes and villains vanished in an instant.

Then, there was sunlight. 

Izuku hit the ground with the practiced grace of a seasoned combatant, rolling over his shoulder to disperse the kinetic energy before springing to his feet. He dropped into a low, defensive crouch, arms raised in a classic boxing guard, One For All humming at a steady five percent. 

His eyes scanned his surroundings with terrifying speed. 

Threat assessment. Unknown environment. Daylight. No rain. Air quality is... clean. Too clean. No smell of burning cordite or collapsed concrete.

He was in an alleyway, but the architecture was entirely wrong. Instead of the towering steel and glass of Musutafu or the brutalist concrete of Tokyo, he was surrounded by cobblestone and structures built of aged brick and timber. 

He tapped the earpiece hidden beneath his cowl. "All Might? Endeavor? Hawks, do you copy?"

Static. Absolute, dead static.

Izuku swallowed hard, fighting down the rising tide of panic. He closed his eyes for a fraction of a second, reaching inward. The vast, starry expanse of One For All remained, the comforting presence of the past users flickering like distant flames. He wasn't cut off from his power. Danger Sense was quiet—an unfamiliar, jarring silence that almost made his head spin. For the first time in months, no one within his immediate vicinity was radiating malice toward him.

Suddenly, a loud, startled gasp echoed to his right.

Izuku pivoted, his green lightning flaring brighter, ready to summon Blackwhip at a moment's notice. 

Standing a few feet away, blinking owlishly against the sudden sunlight, was a teenager. He wore an eccentric, matching black, orange, and white tracksuit. In one hand, he loosely gripped a plastic convenience store bag; in the other, a cup of instant ramen. He had sharp, somewhat intimidating eyes, but his posture screamed of a complete lack of martial training.

Izuku’s tactical mind processed the boy in an instant: Civilian. Unarmed. Poor spatial awareness. No visible Quirk mutations. Threat level: Zero.

The boy dropped his plastic bag. A bag of corn chips spilled onto the cobblestones. He rubbed his eyes, looked at the brick walls, looked up at the sky, and then finally looked at Izuku. 

"Whoa," the boy breathed, his voice tinged with a bizarre mix of awe and confusion. He pointed a trembling finger at Izuku. "Are... are you an NPC? Or did you get summoned too?"

Izuku blinked, the green lightning receding into his skin. He slowly lowered his guard, though his muscles remained coiled like springs. "Summoned?" Izuku asked, his voice rough and scratchy from disuse. He pulled down his metal mouth-guard to speak more clearly. "Are you a civilian? Were you caught in a villain attack? A warp Quirk?"

The boy laughed, a slightly hysterical sound. He slapped his own cheeks with both hands. "A Quirk? Bro, look around! We aren't in Japan anymore! This is it! The sacred event! The hallmark of modern light novels!" The boy struck a dramatic, exaggerated pose, pointing toward the end of the alley where a bustling street could be seen. "I, Subaru Natsuki, have been summoned to a fantasy world!"

Izuku stared at him. The exhaustion clinging to Izuku's bones made the boy's energetic outburst feel like a sledgehammer to the temple. 

Subaru Natsuki, Izuku filed the name away. Possible delusion brought on by shock from spatial displacement. I need to get him to a safe zone, find a local Pro Hero agency, and contact U.A.

"Stay behind me, Natsuki-san," Izuku said, his tone shifting into the calm, authoritative voice he had modeled after All Might. "We don't know the parameters of the Quirk that brought us here. I'm a Hero student, acting under provisional licensing. I'll ensure your safety."

Subaru blinked, looking Izuku up and down. Izuku knew he looked like a nightmare. His hero costume was shredded, stained dark with dried blood and soot. His arms were wrapped in compression sleeves that hid grotesque, jagged scars. The yellow cape around his neck was frayed, and the dark metal soles of his boots were heavily scuffed.

"Hero student?" Subaru echoed, sounding slightly disappointed. "Wait, so you're from Earth too? You're not a local knight or a dark rogue? Man, your cosplay is intense. But hey, if we're an isekai duo, I guess I'm the main protagonist and you're the edgy sidekick with the tragic backstory!"

Izuku didn't answer. He turned his attention to the mouth of the alleyway, taking cautious, measured steps toward the light. Subaru followed, rambling excitedly about magic elements and elf girls.

As they stepped out of the shadows and into the main thoroughfare, Izuku stopped dead in his tracks. 

It was a city unlike anything he had ever seen. The streets were teeming with people, but the sheer variety of physical forms defied logic. There were humans, yes, but walking alongside them were humanoid lizards in armor, men with the heads of dogs, and women with feline ears and tails. Carriages drawn by massive, reptilian beasts akin to earthbound dragons rumbled over the cobblestones. There were no power lines. No cars. No neon signs or glass skyscrapers.

"Heteromorphic type Quirks..." Izuku muttered, his eyes widening. His hand instinctively shot to his utility belt, pulling out a battered, water-damaged notebook and a ballpoint pen. He began to scribble furiously, his voice dropping into a rapid-fire murmur. 

"The population density of heteromorphic mutations here is staggeringly high, easily surpassing the global average of twenty percent. Wait, the infrastructure doesn't support a technologically advanced society. Pre-industrial architecture. No visible communication networks. Are we in an isolated, Quirk-dominated commune? Or a facility hidden off the grid? But the sky, the air pressure, the position of the sun—it doesn't align with Japan's current longitude and latitude..."

Subaru stared at the muttering, scarred teenager next to him, sweat-dropping. "Uh, dude? You're doing a really creepy chanting thing. And you're completely ignoring the obvious! We've been Isekai'd! This is a magical fantasy world!"

Subaru ran up to a nearby merchant stall. Izuku quickly followed, keeping a protective distance, his eyes constantly scanning the rooftops for snipers or aerial threats. 

The stall was manned by a burly man with a green bandana, selling red, apple-like fruits. 

"Hey there, good sir!" Subaru grinned, leaning on the wooden stall. "I'm new in town! Tell me, what kind of magic do you specialize in?"

The merchant, Kadomon, scowled. He crossed his thick arms, a prominent scar visible on his face. "Magic? What are you babbling about, kid? You gonna buy an appa or just waste my time?"

"Appa? You mean apple?" Subaru grabbed one of the fruits. "So, this is the currency of the realm, huh? Let's see..." Subaru pulled a coin purse from his pocket and slapped a modern Japanese 500-yen coin onto the wood. "Keep the change."

Kadomon picked up the coin, bit it, and spat in disgust. "What is this junk? This isn't a holy coin. Get lost before I call the guards. I ain't running a charity for broke weirdos in tracksuits."

"Wait, wait! It's real money!" Subaru panicked, looking at Izuku. "Hey, Hero-guy, back me up here! You got any local currency?"

Izuku stepped forward. He gently placed a hand on Subaru's shoulder, pulling him back a step to de-escalate the situation. "I apologize for the intrusion, sir," Izuku said, bowing deeply to the merchant. "My companion is disoriented. We will leave you to your business."

Kadomon’s scowl softened slightly at the boy's polite demeanor, though he eyed Izuku’s battered, imposing outfit with wariness. "Just keep moving. Don't need trouble."

Izuku steered Subaru away. "Natsuki-san, our currency holds no value here. Furthermore, observing the socio-economic interactions of the populace, the concept of 'Quirks' does not seem entirely synonymous with whatever this society is."

"Because it's magic!" Subaru groaned, dragging a hand down his face. "Come on, Midoriya—is that what you said your name was? Look at this place! The giant lizards! The dog-men! This is straight out of an RPG. We just need to figure out our stats and find the guild."

Izuku frowned, looking at his scarred hands. If this really is another world... what about Mom? What about U.A.? What about the war? A cold knot of dread formed in his stomach. Shigaraki was still out there. If Izuku wasn't there to stop him, Japan—no, the world—would burn. 

Focus. Panic helps no one. Assess the situation. Survive. Find a way back. 

"Let's gather more information," Izuku said, his voice hardening with resolve. "We need a vantage point, and we need to avoid drawing attention to ourselves."

"Avoid attention? Are you kidding?" Subaru grinned, puffing out his chest. "We're the summoned heroes! We're supposed to draw attention! Watch, I bet a beautiful girl is going to bump into me any second now and start my epic quest!"

Subaru confidently marched down the street, blindly turning back into a narrow, shaded alleyway. Izuku sighed, a sound that carried the weight of someone twice his age, and followed close behind. 

As they walked deeper into the alley, the ambient noise of the bustling street faded, replaced by the damp drip of water and the scuffling of rats. The light grew dim. 

Izuku’s Danger Sense suddenly flared—a sharp, stinging needle in the front of his brain. 

He stopped instantly. "Natsuki-san. Stop."

Subaru paused, looking back. "Huh? What's wrong?"

"We're surrounded."

From behind a stack of wooden crates, three figures stepped out. They were typical street thugs. One was huge and burly (Ton), one was lean with a mocking grin (Chin), and the last was short and twitchy, holding a pair of rusted knives (Kan). 

"Well, well," the lean one, Chin, sneered, slapping a crude shortsword against his palm. "Looks like a couple of lost nobles wandered into our territory. Hand over everything you've got, and maybe we won't gut you."

Subaru's eyes lit up. Instead of looking terrified, he looked utterly thrilled. "Yes! Here it is! The obligatory thug encounter to show off my overpowered starting abilities!" Subaru cracked his knuckles, stepping in front of Izuku. "Stand back, Midoriya. Let me handle this. I've been waiting for this moment."

Izuku’s brow furrowed beneath his cowl. "Natsuki-san, wait. Their stances are unrefined, but they are armed with lethal weaponry. If you don't have a combat-oriented Quirk—"

"I got this!" Subaru shouted. He charged at the burly thug, pulling back his fist. "Take this! The wrath of the summoned—!"

Ton simply swatted Subaru out of the air. A massive, heavy backhand caught Subaru squarely in the face. The sickening crack of a breaking nose echoed in the alley. Subaru hit the cobblestones hard, tumbling like a ragdoll. 

"Gah! Ahhh! My nose! It actually hurts!" Subaru screamed, clutching his face as blood poured between his fingers, his gamer fantasy shattering against the brutal reality of physical pain. 

"What an idiot," Kan giggled, twirling his knives. "Let's strip 'em. You," he pointed a blade at Izuku. "Take off that weird green costume and hand over any coin. Now."

Izuku looked at Subaru writhing on the ground. Then, he looked at the three thugs. 

A profound, chilling silence fell over the boy in green. The exhaustion and uncertainty that had plagued him since his arrival vanished, replaced instantly by the cold, calculated focus of a veteran of the Paranormal Liberation War. He had fought a god-like villain who could decay cities with a touch. He had fought an assassin with a sniper rifle that fired hyper-velocity bullets. 

Three men with rusty knives were less than nothing. 

"I strongly suggest you drop your weapons and surrender," Izuku said, his voice devoid of anger, but carrying an intense, atmospheric pressure that made the air in the alley feel heavy. 

Chin laughed, though it sounded slightly nervous. "Tough guy, huh? Kill him!"

The three of them lunged simultaneously. 

One For All: Full Cowling - 5%.

Emerald lightning erupted in the dim alleyway, illuminating the grimy brick walls in brilliant, strobing flashes of green. The air cracked like a whip.

To Subaru, peering through tear-filled, bloodshot eyes, it looked as though Izuku had simply teleported. 

Izuku vanished from his spot. In less than a tenth of a second, he appeared directly in front of the massive thug, Ton. Izuku didn't throw a full punch—the force of One For All would shatter the man's ribs and likely his organs. Instead, Izuku used an open palm, executing an open-handed palm strike to the man's solar plexus with pinpoint, surgical precision.

Ton's eyes bulged. All the air violently evacuated his lungs in a sharp whoosh. He collapsed instantly, unconscious before his knees hit the dirt.

"What the—!" Chin yelped, trying to swing his sword. 

Izuku ducked under the erratic, telegraphed swing with effortless grace. He grabbed Chin's wrist, applied pressure to the nerve bundle, forcing the thug to drop the sword, and used the man's own momentum to flip him over his shoulder. Chin slammed onto the cobblestones with a heavy, breath-stealing thud. Izuku swiftly delivered a precise chop to the side of Chin's neck. Two down. 

Kan, the knife wielder, shrieked in terror and thrust his twin blades toward Izuku's back. 

Izuku didn't even turn around. Danger Sense painted the trajectory of the knives in his mind. He simply sidestepped. The blades missed him by a millimeter. As Kan stumbled forward, off-balance, Izuku flicked two fingers against his thumb. 

Delaware Smash - Air Force.

He didn't use the full force of a 20% flick. He used just enough. A highly compressed bullet of air shot from Izuku's fingers, striking Kan squarely in the center of the forehead. It hit with the force of a rubber bullet fired from a shotgun. Kan's eyes rolled back into his head, and he crumpled into a heap alongside his comrades.

The fight had lasted precisely 2.4 seconds.

The green lightning faded, sinking back beneath Izuku's skin. The alley was dead silent, save for Subaru’s ragged breathing.

Izuku turned around, kneeling beside Subaru. He pulled a clean roll of gauze from one of his utility pouches—a standard first-aid supply he always kept on hand. 

"Hold still, Natsuki-san," Izuku said softly, his voice returning to the gentle, polite tone of a teenager. He expertly applied pressure to Subaru's nose, tilting the boy's head forward, not backward, to prevent blood from running down his throat. "It's a clean break. Painful, but manageable."

Subaru stared at Izuku, his mouth hanging open, completely ignoring the pain in his face. "You... what are you? Was that magic? You moved like a... like an anime character! You just took down three guys without even trying!"

"It's a Quirk," Izuku corrected gently, wrapping the gauze. "Superhuman physical enhancement. It's... it's a power passed down to me to protect others."

Before Subaru could press further, Izuku's head snapped up. Danger Sense gave a low, mild thrum. Not lethal danger. Just a warning of rapid approach.

A small blur of blonde hair and rags sprinted past the mouth of the alleyway, moving incredibly fast. A moment later, a voice rang out.

"Stop right there! Give it back!"

Izuku stood up, peering out of the alley. A girl with long, shimmering silver hair and striking amethyst eyes skidded to a halt near the alley entrance. She wore an elegant white and purple dress that seemed entirely out of place in the slums. 

She looked frantically in the direction the blonde girl had run, then her gaze drifted into the dark alley, locking onto the scene: Three unconscious, battered thugs, a bleeding Subaru, and a scarred boy in a ragged green costume radiating an aura of intense, suppressed power.

The silver-haired girl raised her hands. The air temperature in the alley instantly plummeted. Frost began to crystallize on the cobblestones, and several jagged, razor-sharp spears of ice materialized out of thin air, hovering defensively around her.

"Whatever you're planning, I won't let you," the girl said, her voice trying to sound stern, though Izuku could hear the underlying tremor of anxiety. "I don't have time to deal with ruffians. Hand over my insignia, right now."

Izuku’s eyes locked onto the floating ice. Cryokinesis. No, the molecular structure of the air didn't just freeze—she manifested the ice from an external energy source. A creation-type ability? Or elemental manipulation?

"Hold your fire!" Subaru yelled from the ground, scrambling to his feet despite his bloody nose. "We're not the bad guys! Well, he's not! Those guys attacked us, and my boy Midoriya here just went full Bruce Lee on them!"

The girl paused, her amethyst eyes darting from the unconscious thugs to Izuku. "You... you fought them?" 

A small, grey cat with a pink nose and an oversized tail suddenly materialized out of thin air, floating lazily beside the girl's shoulder. 

"Now, now, Lia," the floating cat spoke, its voice cheerfully masculine. "The boy in the tracksuit is telling the truth. These three have a nasty aura, but the green one? He feels... strange. Like a void. But he has no malice." 

Izuku’s notebook was instantly back in his hands. "A sentient familiiar? Telepathy? Or a manifestation of a secondary consciousness Quirk?" he muttered rapidly, writing so fast his pen was a blur. "And what did he mean by 'void'? Does he sense the absence of a Quirk factor? Or is he referring to the vestige realm?"

"He's doing it again," Subaru sighed, pointing at Izuku. "Don't mind him. He's got a mutter-habit."

The girl—Lia—lowered her hands, and the ice spears dissipated into sparkling mist. Izuku stopped writing, noting how cleanly the energy dispersed. 

"I... I see," the girl said, looking slightly embarrassed. She walked deeper into the alley, crouching beside the unconscious thugs. To Izuku's surprise, she placed her hand over Ton's chest. A soft, pale light emitted from her palm.

Healing Quirk, Izuku noted, his eyes widening. Healing abilities were incredibly rare in his world. Recovery Girl was one of the few.

"What are you doing?" Subaru asked, echoing Izuku's internal thoughts. "Those guys just tried to rob us!"

"They're still hurt," she said softly, not looking up. "I can't just leave them bleeding. But... I don't have much time. Something very precious was stolen from me. A little blonde girl ran this way. Did you see her?"

Izuku stared at the silver-haired girl. He saw the tension in her shoulders, the desperation in her eyes, and the fundamental, irrational kindness of stopping to heal the very people who would have gladly harmed her, simply because they were injured. 

In that moment, Izuku Midoriya saw something familiar. He saw a Hero. 

He didn't know where he was. He didn't know if he would ever see his mother, All Might, or his classmates again. He didn't know how to get back to his war-torn world. But staring at this girl, the heavy, suffocating anxiety in his chest loosened, just a fraction. 

The world had changed, but the mission hadn't. There was someone in front of him who needed help. 

Izuku stepped forward, pulling his yellow cape back over his shoulder. He stood tall, projecting the confident, reassuring presence of a Pro Hero. 

"I saw her," Izuku said, his voice steady and clear. "She went south, utilizing a high-speed traversal method. My name is Izuku Midoriya. I am a Hero. And if someone stole something precious to you, then I will help you get it back."

The silver-haired girl looked up at him, her amethyst eyes widening in surprise at the sheer, unshakeable conviction in the boy's battered face. 

Subaru wiped the blood from his upper lip, grinning widely. He threw an arm around Izuku's shoulder, wincing as he stretched his face. "And I'm Subaru Natsuki! We're a package deal. Consider this the start of our legendary party!"

The floating cat, Puck, chuckled, doing a small loop in the air. "Well, Lia? Looks like you've found yourself some peculiar knights."

The girl stood up, a small, genuine smile breaking through her worried expression. "My name... is Emilia. Just Emilia. And... thank you. Both of you."

Izuku nodded, his eyes glowing with a faint trace of emerald light. The Paranormal Liberation War felt a universe away. Right here, in this strange alleyway in a world of magic and monsters, a new mission had begun. 

And Izuku Midoriya, the Symbol of Hope, would not let her down.

The slums of the Royal Capital of Lugunica smelled of stagnation. It was a scent Izuku Midoriya was unfortunately familiar with—a mixture of rotting wood, damp earth, unwashed bodies, and the quiet, desperate sorrow of people who had been left behind by society. 

As the unlikely quartet—a Hero, a stranded teenager, a half-elf silver-haired girl, and a floating cat spirit—navigated the labyrinthine alleys of the lower district, Izuku’s mind was running a mile a minute. 

His emerald eyes, shadowed slightly by the tattered rim of his cowl, tracked the movement of the locals. He saw children with dirt-smudged faces peering at them from behind overturned crates. He saw demi-humans with hollow eyes sitting in the shade of dilapidated brick buildings. There were no Pro Heroes patrolling these streets. There were no police sirens wailing in the distance. This was a place where the law of the strong ruled absolute. 

It’s like Kamino Ward before the raid, Izuku thought, a familiar pang of anxiety tightening his chest. Or the back-alleys where Overhaul hid the Shie Hassaikai. Poverty and despair breed crime, no matter what world you're in. Emilia-san said the insignia stolen from her was vital to the nation's future. If the thief brought it here, they intend to fence it on the black market.

"Hey, Midoriya," Subaru whispered, jogging slightly to keep pace with Izuku's long, measured strides. The boy was holding a makeshift ice-pack—conjured by Puck—against his bruised and bandaged nose. "You're doing the scary glaring thing again. You look like you're about to punch a building."

Izuku blinked, the intensity in his gaze softening. "Ah, sorry, Natsuki-san. I'm just... mapping the area. If we get into an altercation, I need to know the structural integrity of these buildings. The wood is rotted, and the masonry is crumbling. If I use too much power, the collateral damage could collapse an entire block. I'd have to keep One For All below five percent, maybe restrict myself entirely to capture techniques."

Subaru stared at him, his jaw slackening. "Bro, you talk about destroying city blocks like you're deciding what to have for lunch. Just how overpowered are you? Are you the hidden boss of this tutorial stage?"

"It's not about being overpowered," Izuku said, his voice lowering, the weight of the Paranormal Liberation War bleeding into his tone. "It's about controlling what you have so you don't hurt the people you're trying to save." 

Ahead of them, Emilia glanced over her shoulder, her amethyst eyes filled with a mixture of gratitude and profound curiosity. "You two are very strange," she remarked, her voice carrying a melodic, yet melancholy cadence. "You don't wear the crests of any noble house, nor the armor of the Royal Guard. Yet, Midoriya, you carry yourself with the discipline of a seasoned knight. And Subaru... well, you are very brave, despite lacking any mana."

"I have the heart of a lion, Emilia-tan!" Subaru declared, puffing out his chest and striking a pose, completely ignoring the throbbing pain in his face. "And a lion doesn't need magic to protect a beautiful maiden!"

Emilia tilted her head, clearly entirely unfamiliar with the suffix '-tan' and the sheer audacity of Subaru's flirting. "Emilia... tan? Is that a title from your homeland?"

While Subaru launched into a frantic, comedic explanation of Japanese honorifics, Izuku felt a strange sensation near his ear. He glanced to his left to see Puck, the small grey cat familiar, floating mere inches from his face. Puck’s dark, fathomless eyes were staring intently into Izuku’s.

"You know," Puck said cheerfully, stroking his whiskers, "Lia is right. You are a very strange boy, Izuku."

Izuku stiffened slightly, wary of the sentient creature. "Strange how, Puck-san?"

"Just Puck is fine," the spirit replied, doing a lazy barrel roll in the air. "I'm a Great Spirit. I can sense the Od—the mana, the life energy—in every living thing. Even Subaru here has a tiny, sluggish little gate. But you?" Puck drifted closer, poking Izuku's cheek with a tiny paw. "You are completely, utterly empty. You don't have a drop of mana in your body. It's like looking at a rock, or a void."

Izuku filed that information away. So, mana is the power system of this world. And because I'm from Earth, I don't possess the biological organs or spiritual pathways to generate it.

"But," Puck continued, his cheerful voice dropping an octave, carrying an ancient, weighty timber that made the hairs on Izuku's arms stand up, "that's not the strangest part. You have no mana... but your soul is overflowing. I've never seen anything like it. It's like there are multiple, massive souls layered over your own, burning like suns. Six... no, seven other presences inside you. What exactly are you, Izuku?"

Izuku’s breath caught in his throat. His hand instinctively flew to his chest, right over his heart, where the core of One For All rested. 

He can sense the Vestiges? Izuku thought, his mind racing. Even All For One could only interact with them through direct contact or profound emotional resonance. This spirit can sense the past users just by looking at me!

Before Izuku could formulate a response that wouldn't reveal the deepest secrets of his Quirk, Emilia suddenly stopped.

"We're here," she said, her voice tight. 

They stood before a massive, looming structure. It was built of dark, stained wood and looked like a swollen, misshapen barn that had been grafted onto the ruins of a larger stone building. The windows were boarded up, and a heavy, iron-reinforced door stood as the only entrance. The sign above the door was faded, but the sheer oppressive aura of the place made its purpose clear.

"The Stolen Goods Storehouse," Subaru read, translating the vibe rather than the actual text. "A classic den of thieves. Alright, Midoriya, what's the plan? Do we kick down the door? Flashbang them with a magic crystal?"

Izuku stepped forward, his eyes narrowed. "We don't kick down anything. There might be civilians inside, or the thief might have hostages. We go in quietly. We negotiate. If negotiations fail, I will immobilize them."

He gently pushed the heavy wooden door open. The hinges groaned in protest. 

The interior was cavernous and dimly lit by a few scattered magic lanterns emitting a pale, sickly yellow glow. Dust motes danced in the stale air. The room was cluttered with mountains of stolen goods: rusted armor, crates of illicit spices, stolen tapestries, and broken weapons. It looked like a dragon's hoard made of garbage.

"Hello?" Emilia called out, stepping into the room, her hands slightly raised, ready to summon ice at a moment's notice. "Is anyone here? I am looking for a blonde girl. She took something that belongs to me."

From the shadows behind a massive, makeshift wooden counter, a colossal figure rose. 

Subaru yelped and took a step back. 

The man was easily over seven feet tall, built like a mountain of muscle, with a bald head, a thick white beard, and scars crisscrossing his massive arms. He glared down at the intruders with eyes like tempered steel. This was Old Man Rom, the giant of the slums.

"We're closed," Rom rumbled, his voice like grinding boulders. He reached behind the counter and casually lifted a wooden club the size of a tree trunk. "And we don't take kindly to nobles or their lapdogs wandering into the slums making demands."

"We aren't looking for a fight," Izuku said, stepping in front of Emilia and Subaru. He raised his hands in a placating gesture. "My name is Izuku Midoriya. We are looking for a young girl. She stole an insignia. If you have it, we are willing to negotiate for its return."

Rom sneered, hoisting the massive club onto his shoulder. "Negotiate? Kid, you're wearing rags, and your friend is bleeding on my floor. The half-elf might have some coin, but I don't deal with her kind. Now get out, before I swat you like flies."

Subaru, emboldened by having an overpowered anime protagonist by his side, stepped out from behind Izuku. "Hey, you big gorilla! You better watch your mouth! My buddy here just laid out three guys in less than three seconds! You don't want this smoke!"

Natsuki-san, please stop antagonizing the giant, Izuku groaned internally. 

Rom’s eyes narrowed. "Is that a threat, brat?" 

With a roar that shook the dust from the rafters, Rom swung the massive tree-trunk club. He didn't aim for Subaru; he aimed squarely at the center of the group, a sweeping horizontal strike meant to crush all three of them against the wall. The sheer kinetic force of the swing created a gust of wind in the enclosed space.

Emilia gasped, her hands glowing with pale light, but the club was moving too fast for her to form a solid ice barrier in time.

Izuku didn't blink. He didn't even shift into a combat stance. He simply exhaled. 

Blackwhip.

From Izuku's right arm, a torrent of thick, crackling black tendrils erupted. They didn't shoot out like ropes; they exploded outward like living, angry shadows, edged with a faint, volatile green luminescence. 

The black tendrils slammed into the descending wooden club. 

CRACK.

The sound of the impact was deafening. Rom's eyes widened in sheer, unadulterated shock as his massive, two-handed swing was stopped dead in its tracks. The club didn't budge an inch further. The black tendrils had wrapped around the wood like iron pythons, absorbing the kinetic energy completely.

Puck, floating near the ceiling, felt his jaw drop. No incantation. No mana gathered from the atmosphere. No fluctuation in his Od. He just... manifested raw, physical energy out of absolutely nothing?!

Before Rom could pull the club back, Izuku flicked his wrist. The black tendrils surged forward, moving like vipers. In the blink of an eye, they wrapped around Rom's massive wrists, his torso, and his ankles. With a sharp tug, Izuku hoisted the seven-foot giant off the ground, suspending him in mid-air. 

"What the—?!" Rom bellowed, struggling against the bindings. But the Blackwhip was born from the power of One For All; it possessed the tensile strength of steel cables. The more Rom struggled, the tighter they held. 

"I told you," Izuku said, his voice calm, but echoing with an unnatural resonance. He held his hand out, keeping the giant suspended with effortless ease. "We don't want to fight. Please, calm down."

"Gramps!" a panicked voice shrieked from the rafters.

A small blur dropped from the shadows above. It was Felt, the blonde thief. She landed nimbly on the counter, a small dagger drawn, her red eyes wide with terror as she looked at the giant suspended in the air by shadows. 

"Let him go!" Felt yelled, pointing the dagger at Izuku. "Let him go, or I'll cut you!"

"You're the girl from the alleyway," Emilia stepped forward, her voice laced with relief and stern authority. "You stole my insignia. Give it back to me. It's incredibly dangerous for you to have it."

Felt grit her teeth, looking between the glowing ice forming in Emilia's hands and the terrifying black tendrils sprouting from Izuku's arm. "I... I can't! I already promised it to a buyer! She's supposed to be here any minute! If I give it to you, she'll kill me!"

Izuku frowned. He released his grip, and the black tendrils dissipated into black smoke. Rom crashed to the floor, coughing and rubbing his wrists, staring at Izuku with a newfound, terrified respect. 

"A buyer?" Izuku asked, stepping closer to the counter. "Who hired you to steal it?"

"I don't know her name!" Felt yelled defensively. "She's just a lady in black. She offered me twenty holy coins for it. I live in the slums! I couldn't pass that up!"

"Twenty holy coins?!" Rom gasped from the floor. "Felt, you idiot! You stole from a noble candidate for twenty coins?!"

"We will match the price," Subaru suddenly interjected, stepping up to the counter and digging into his tracksuit pocket. "Look, we don't have your currency, but I have this!" He slammed his flip-phone onto the wood. "It's a metia! A magical device from my homeland that can capture moments in time! It's worth at least fifty holy coins!"

Felt and Rom looked at the plastic device with intense skepticism. 

"A metia?" Rom murmured, pushing himself off the floor. "I've heard of them. If it's real..."

Izuku let Subaru handle the haggling. His eyes were scanning the room. Something felt wrong. The air in the storehouse had suddenly grown cold. It wasn't the frosty chill of Emilia's magic. It was a damp, creeping chill. The hairs on the back of Izuku's neck stood up. 

Then, it happened. 

Danger Sense didn't just thrum. It exploded. 

It was as if a jagged, rusted nail had been driven directly through the center of Izuku's forehead. The pain was blinding, white-hot, and suffocating. It was a level of pure, concentrated malice that he hadn't felt since he stood across from Tomura Shigaraki on the floating coffin of U.A. 

Lethal threat. From the shadows. Targeting... Natsuki-san!

Time dilated. The world around Izuku slowed to a crawl. He saw Subaru grinning, holding up his cell phone. He saw Felt reaching out to touch it. And out of the corner of his eye, emerging from the pitch-black shadows near the entrance, he saw a blur of black fabric and the glint of a curved, metallic blade thrusting directly toward Subaru's stomach.

"Natsuki-san! MOVE!" 

Izuku didn't have time to use Blackwhip. He didn't have time to warn them. 

One For All: Full Cowling - 10%.

Green lightning shattered the gloom of the storehouse. The wooden floorboards beneath Izuku's iron soles exploded into splinters as he launched himself forward with terrifying velocity. 

Subaru only saw a flash of green. The next thing he knew, a force like a speeding truck slammed into his side. Izuku tackled him, throwing them both violently across the room, crashing into a pile of stolen tapestries. 

SHING.

The sound of metal slicing through air and fabric rang out. 

Where Subaru had been standing a millisecond prior, a woman now stood. She held a curved Kukri knife. The blade was gleaming, and on the very tip of the metal, a single, bright red drop of blood gathered before falling to the floor. 

Izuku scrambled to his feet, pulling Subaru up by his collar and shoving him behind his back. Izuku reached up and touched his left cheek. His finger came away red. The blade had grazed him in his desperate tackle. 

"Oh, my," a voice purred. It was a soft, sultry, and terrifyingly sweet voice. 

The woman stepped fully into the pale light of the lanterns. She wore a revealing black dress, a dark cloak, and had long, braided black hair. Her skin was incredibly pale, but it was her eyes that made Izuku's blood run cold. They were a vivid, piercing purple, and they held absolutely no human empathy. They were the eyes of a predator looking at a slaughterhouse. 

This was Elsa Granhiert, the Bowel Hunter. 

"I was aiming for the boy in the odd clothing," Elsa smiled, running her tongue over her lips as she looked at Izuku. "I wanted to see the color of his bowels. But you... you moved incredibly fast. And you bleed such a vibrant red."

"Who the hell are you?!" Subaru yelled from behind Izuku, clutching his chest, his heart hammering against his ribs. He realized, with a sickening drop in his stomach, that if Izuku hadn't tackled him, his guts would currently be spilling onto the floorboards. 

"Are you the buyer?" Felt asked, stepping back, her dagger trembling in her hand. "Hey! We had a deal! Why are you attacking us?!"

Elsa giggled, a chilling sound. "The deal was that you bring me the insignia, and you don't look into who hired me. But now, the owner is here. The employer's instructions are clear: leave no witnesses. That means everyone in this room has to die. Especially you, little thief. I think I'll open your stomach first."

Emilia stepped forward, her face pale but resolute. Sharp icicles formed in the air around her. "You are an assassin. I won't let you hurt anyone here."

"Oh, a spirit arts user?" Elsa's smile widened. "How delightful. But ice is so cold. Blood is much warmer."

Izuku slowly took a step forward, putting himself directly between Elsa and the others. The green lightning crackled across his skin, illuminating the dust in the air. 

He had fought villains before. He had fought Muscular, a man who loved violence. He had fought Overhaul, a man who saw humans as a plague. He had fought Stain, a zealot who believed he was culling a corrupt society. 

But as Izuku looked at Elsa, his analytical mind hit a wall. There was no grand ideology here. There was no twisted desire to reshape society. There was no trauma masking a cry for help. 

She just wanted to cut people open. She enjoyed it. It was pure, unadulterated, chaotic evil. 

"Emilia-san, Puck, get Natsuki-san, Rom, and Felt out of here," Izuku commanded, his voice dropping an octave, carrying the absolute authority of the Symbol of Peace. "Evacuate the building. Now."

"Midoriya, you can't fight her alone!" Subaru yelled. "She's crazy! She's got weapons!"

"I am a Hero," Izuku said, never taking his eyes off Elsa. "My job is to fight the crazy ones. Go!"

Elsa laughed, a melodic, psychotic sound. "A hero? How charming! Let's see if your bowels are as heroic as your words!"

She vanished. 

To a normal human eye, Elsa Granhiert simply ceased to exist. She moved with superhuman speed, a blur of black fabric and flashing steel. 

But Izuku wasn't a normal human. 

Danger Sense shrieked, a warning from his left blind spot. 

Izuku ducked. The Kukri knife cleaved through the space where his neck had been a fraction of a second prior, severing a few strands of his wild green hair. 

Izuku spun on his heel, channeling eight percent of One For All into his right leg. He unleashed a sweeping crescent kick, aiming for Elsa's ribs. The iron sole of his boot whistled through the air. 

CLANG.

Elsa blocked the kick with the flat of her blade. The sheer kinetic force of Izuku's blow sent a shockwave through the room, blowing the dust away and shattering a nearby lantern. Elsa was pushed back, her boots skidding across the wooden floorboards, leaving deep gouges in the wood. 

She looked at her trembling arm, her eyes widening in pure, ecstatic delight. "Oh! Oh, wonderful! Such incredible strength! What are you? A demi-human? A beast warrior? Your body is small, but you hit like a Ground Dragon!"

Izuku didn't answer. He couldn't afford to. He closed the distance in a heartbeat. 

He unleashed a flurry of punches. Detroit Smash - Rapid Fire. He kept the power low—around five to eight percent—to avoid killing her, aiming for pressure points and joints to disarm her. 

Elsa met his onslaught with terrifying grace. She pulled a second Kukri knife from her cloak. The dark storehouse erupted into a cacophony of sound. The heavy, meaty thuds of Izuku's fists meeting Elsa's forearms, the ringing clash of iron boots against steel blades, the crackle of green lightning, and the splintering of wood as their high-speed combat tore the room apart. 

She's fast, Izuku analyzed frantically, parrying a thrust that aimed for his liver. Faster than Stain. Almost as fast as Lady Nagant in close quarters. Her center of gravity is flawless. But her strength is lower than mine. I can overpower her, but those knives... if I miscalculate by a millimeter, I lose a limb.

"Beautiful!" Elsa panted, her face flushed with a sick thrill as she slashed wildly at Izuku's chest. "Dance with me! Let me see your insides! I want to feel your heat!"

"You're insane!" Izuku grunted. He leaned backward, avoiding a horizontal slash that tore through the fabric of his dark green shirt. 

As Izuku leaned back, Elsa saw an opening. She lunged forward, thrusting both knives downward in a crossed pattern, aiming to pin Izuku to the floor. 

It was a fatal strike. 

But Izuku Midoriya had more than one Quirk. 

Float.

Izuku suspended his own gravity. Instead of falling backward onto the floor, he simply stopped in mid-air, hovering parallel to the ground. 

Elsa's knives struck the wooden floorboards, embedding themselves to the hilts. She gasped in shock, staring down at the boy who was defying the laws of physics. 

"What?" she breathed. 

Taking advantage of her momentary shock, Izuku spun his body while floating, bringing his iron-soled boot around in a brutal, sweeping axe kick. 

Smash!

The kick connected solidly with Elsa's shoulder. There was a sickening CRUNCH of bone. Elsa was launched across the room like a cannonball, smashing through a solid oak support pillar and crashing into a pile of stolen armor. The roof of the storehouse groaned dangerously.

Izuku dropped back to the floor, panting. He wiped a trickle of blood from his cheek. He looked toward the entrance. Emilia and the others had retreated to the doorway, watching the battle with unadulterated awe and terror. 

"Midoriya!" Subaru cheered, pumping a fist. "You got her! You broke her arm!"

"Stay back!" Izuku roared. Danger Sense was still screaming. The malicious aura hadn't faded; if anything, it had grown more intense. 

From the pile of rubble, Elsa slowly stood up. Her left arm was hanging at a grotesque, unnatural angle. Her shoulder was clearly shattered. 

But she was smiling. 

She reached up with her right hand, grabbed her broken left arm, and with a sickening crack, snapped the bone back into place. A faint, dark mist seemed to emanate from the wound. In seconds, she rotated the previously shattered shoulder as if nothing had happened. 

Izuku's eyes widened in horror. Super-regeneration?! Like a High-End Nomu?! 

"That hurt," Elsa giggled, wiping dust from her black dress. "It hurt so wonderfully. You are full of surprises, flying boy. You possess no mana, yet you hit with the force of a giant and dance on the air. I must have your bowels. I simply must."

Izuku’s mind raced. Standard apprehension tactics are useless against regeneration of that caliber. If I hold back, she'll outlast my stamina and kill everyone here. I can't use 100%—the shockwave would destroy the building and kill Emilia-san and the others. I need a concentrated, overwhelming attack. Something that incapacitates her nervous system instantly without killing her.

He took a deep breath. The starry void of One For All swirled within him. He reached out to the third user, and the sixth. 

Fa Jin.

Smokescreen.

From Izuku's body, a massive, billowing cloud of thick, purple smoke erupted. It poured out of him like a geyser, filling the cavernous storehouse in seconds. The pale light of the lanterns was completely choked out. Visibility dropped to absolute zero. 

"Oh?" Elsa's voice drifted through the fog, sounding amused. "A smokescreen? Are you trying to hide, little hero? I can hear your heartbeat. I can smell your blood."

Outside the building, Emilia coughed, waving her hand. "Puck! Can you clear the smoke?"

"I wouldn't," Puck warned, hovering near Emilia's shoulder. "The boy is doing something in there. The air pressure is dropping. He's gathering energy. An unbelievable amount of it."

Inside the smoke, Izuku wasn't hiding. He was bending his knees, bouncing rapidly on his toes. Squat, jump, land. Squat, jump, land. With every movement, he was storing kinetic energy, building it up in his muscles through Fa Jin. 

Elsa moved through the purple fog like a phantom. She listened. There. The sound of rapid movement. She grinned, her purple eyes glowing in the dark. She lunged toward the sound, her Kukri knife raised for a lethal strike. 

But Izuku's Danger Sense allowed him to track her perfectly through the smoke. He didn't need to see her. He could feel her malice approaching. 

Kinetic energy stored. One For All: 20%. Plus Fa Jin!

Izuku stopped bouncing. He planted his left foot firmly on the ground, anchoring himself. 

Elsa burst through the smoke, her blade descending toward his neck. 

Izuku twisted his torso, generating maximum torque, and brought his right leg up in a devastating, high-angle roundhouse kick. The iron sole of his boot met the flat of Elsa's crossed blades. 

St. Louis SMASH!

The impact was cataclysmic. 

The kinetic energy of Fa Jin was released all at once, multiplying the 20% power of One For All into an attack equivalent to nearly 45%. 

The air itself shattered. A massive, concussive shockwave exploded from the point of impact. The purple smokescreen was instantly obliterated, blown away by the sheer force of the wind pressure. 

Elsa's Kukri knives shattered into a million silver fragments. The kick bypassed her guard entirely, sinking deep into her midsection. Her eyes bulged so wide they nearly popped out of her skull as the breath, the blood, and the fight were violently expelled from her body.

The shockwave didn't stop there. It tore through the storehouse. The massive wooden floorboards ripped themselves from the foundation. The heavy oak support pillars snapped like twigs. The roof of the Loot House was blown entirely off its hinges, sent spiraling into the night sky. 

Outside, Subaru, Emilia, Felt, and Rom were thrown to the ground by the gale-force wind, shielding their eyes from the debris. 

When the dust finally settled, the Loot House was gone. It had been reduced to a crater of splintered wood and broken stone, completely open to the starry night sky above the Royal Capital. 

In the center of the crater stood Izuku Midoriya. His right leg was still extended from the kick, green lightning violently sparking off his body. Steam was rising from his muscles, the strain of combining Fa Jin and One For All causing his skin to flush crimson. 

Buried in the rubble thirty feet away was Elsa Granhiert. She was embedded into a stone wall, her body mangled. Her black dress was torn, and she was coughing up copious amounts of blood. 

Izuku slowly lowered his leg, his chest heaving. He glared at the ruined assassin. "It's over. Surrender."

Elsa looked up at him. Through the blood and the pain, her psychotic smile returned. It was weaker, but just as terrifying. 

"Magnificent..." she wheezed, her purple eyes filled with a twisted, obsessive adoration. "Izuku... Midoriya. I will remember that name. Your heat... your power... it is exquisite. I must have it. I will have it."

With a sudden, violent burst of speed fueled by sheer, desperate survival instinct, Elsa tore herself from the rubble. She threw a handful of broken glass and dust into the air as a distraction, her vampire-like cloak billowing around her. 

Izuku lunged forward to pursue, but a sharp spike of pain shot up his right leg—the backlash of using Fa Jin without a proper warm-up. He stumbled, falling to one knee. 

By the time the dust cleared, Elsa was gone, swallowed by the shadows of the slums. 

Izuku slammed his fist into the dirt in frustration. Dammit! She got away. A villain that dangerous, with regeneration and no moral compass, is loose in the city.

"Midoriya!" 

Subaru scrambled over the rubble, completely ignoring his own injuries. He ran up to Izuku, looking at the boy, then looking at the absolute devastation of the building around them. 

"Dude..." Subaru breathed, his eyes wide as saucers. "You... you just blew up a building with a kick. You're not the sidekick. You're the whole damn anime."

Emilia and the others cautiously approached. Rom was staring at Izuku with pure, unadulterated fear. Felt was hiding behind the giant, her red eyes wide. 

Emilia walked up to Izuku. She looked at his bleeding cheek, the burns on his arms, and the utter exhaustion in his posture. Without a word, she knelt beside him. Her hands glowed with pale, soothing light, and she gently placed them on his chest. 

A cool, refreshing energy washed over Izuku. The burning ache in his muscles subsided. The cut on his cheek closed. 

"You saved us," Emilia said softly, her amethyst eyes shining with tears. "You destroyed the storehouse, but... you saved my life. You saved all of our lives. Thank you, Izuku."

Izuku looked at her. He thought of the war. He thought of the cities he had failed to save, the heroes who had fallen while he wasn't fast enough. 

"I'm a Hero," Izuku said quietly, giving her a weak, but genuine smile. "It's what I do."

Suddenly, the sound of slow, measured clapping echoed through the ruined courtyard. 

Izuku's head snapped up, Danger Sense pulsing—not with malice, but with an overwhelming, suffocating sense of power. 

Walking through the rubble with the casual grace of a king strolling through his garden was a young man. He had fiery red hair, piercing blue eyes, and wore the pristine, elegant white uniform of the Royal Guard. A beautifully crafted sword hung at his hip. 

Even without a Quirk, Izuku's combat instincts screamed at him. This man... he's in a completely different league. He feels like All Might.

"A spectacular display," the red-haired knight said, his voice polite, melodic, and completely devoid of fear. He looked at the crater, then at the scattered rubble, and finally, his blue eyes locked onto Izuku. "I felt a disturbance in the mana atmosphere. I hurried here expecting a disaster. Instead, I find a young man who wields the power of a tempest, yet possesses no Od."

The knight stopped a few feet away and bowed gracefully. 

"I am Reinhard van Astrea, of the Royal Guard," the Sword Saint said, smiling warmly. "And I must ask... just who, and what, are you?" 

Izuku slowly stood up, brushing the dirt from his tattered yellow cape. He looked at the Sword Saint, then up at the alien, starry sky of Lugunica. 

"My name is Izuku Midoriya," he replied, his voice ringing clear in the quiet night. "And I think... I have a lot to explain."

The mattress was too soft.

That was the very first thing Izuku Midoriya realized as his consciousness clawed its way out of the dark, exhausted abyss of sleep. For the past several months—ever since he had left U.A. High School, ever since he had taken up the mantle of a solitary vigilante in a ruined Japan—he had slept on concrete rooftops, in abandoned subway stations, or, on rare occasions, on a stiff cot in an All Might statue’s shadow. He was accustomed to waking up to the smell of ash, the distant wail of sirens, and the bone-deep ache of cold dampness.

Here, he smelled lavender. He felt crisp, clean linen. And the air was perfectly, peacefully quiet. 

Izuku’s eyes snapped open. The emerald irises contracted as his pupils adjusted to the morning sunlight streaming through a large, ornate bay window. 

In a fraction of a second, his mind booted up from zero to a hundred, years of brutal combat training taking over. He didn't sit up slowly; he launched himself backward, performing a seamless backhandspring off the plush mattress and landing in a low, defensive crouch in the corner of the room. Green lightning—One For All at a controlled five percent—crackled over his skin instinctively, illuminating the unfamiliar room in brief, strobing flashes. 

Where am I? Threat assessment. Single point of entry: the wooden door. One large window. Third story, maybe fourth, judging by the angle of the sunlight and the tops of the trees outside. No visible hostiles. No immediate malicious intent detected.

Danger Sense was quiet. It wasn't the dead, terrifying silence of being quirk-erased; it was just a dull, ambient thrum, like the low hum of a refrigerator. It meant he was alive, his Quirks were intact, and no one within a several-mile radius actively wanted to kill him. 

Izuku slowly exhaled, the green lightning receding beneath his skin. He stood up, wincing slightly as a dull ache radiated from his right leg—a lingering reminder of the massive Fa Jin enhanced kick he had delivered to the Bowel Hunter, Elsa Granhiert. Emilia’s healing magic had repaired the torn muscle fibers, but the phantom fatigue remained.

He looked down at himself and his breath hitched in his throat. 

He was no longer wearing his ragged, blood-stained hero costume. Gran Torino’s cape was gone. His iron-soled boots were gone. Instead, he was dressed in a simple, oversized white cotton shirt and a pair of loose gray trousers. The compression sleeves that hid the grotesque, jagged scars covering his arms had been removed. 

Panic, cold and sharp, pierced his chest. My gear. My notebooks. 

He scanned the room frantically. It was a lavish guest bedroom, decorated in rich mahogany and emerald greens, with a massive chandelier hanging from the ceiling. There, neatly folded on a polished wooden desk near the window, was his hero costume. It had been scrubbed clean. The bloodstains were gone, the fabric stitched up where Elsa’s blades had torn it. Next to the costume sat his utility belt, and resting perfectly in the center were his burned, water-damaged notebooks. 

Izuku rushed to the desk, running his scarred fingers over the cover of his "Hero Analysis for the Future" notebook. A profound sigh of relief escaped his lips. The secrets of One For All, his notes on Shigaraki, on his friends... they were safe. 

He pulled Gran Torino’s yellow cape over his shoulders, letting it drape over the white cotton shirt like a makeshift shawl. The familiar weight of the fabric grounded him. 

Think, Izuku. Organize the data, he commanded himself, pacing the floor. I was pulled through a spatial anomaly. I arrived in a medieval-level society with a high density of heteromorphic traits and widespread use of energy manipulation dubbed 'magic'. I met Subaru Natsuki, another displaced person from Earth. I encountered Emilia-san, who was targeted by an assassin. We fought. I destroyed the building. A Pro-Hero equivalent—Reinhard—arrived.

He remembered the aftermath in a hazy blur. Reinhard had been incredibly polite, recognizing Emilia's royal crest. The Sword Saint had commended Izuku’s strength but questioned his origins. Emilia, stepping in as a mediator, had claimed Izuku and Subaru as her personal guests, placing them under her protection. Exhaustion had finally claimed Izuku on the carriage ride away from the slums.

"So, I'm in Emilia-san's residence," Izuku muttered, bringing a hand to his chin. "Given the opulence of this room and the architectural style I can see outside, this is an aristocrat's manor. A noble's estate. That means politics. That means I need to be incredibly careful. I don't know the laws here. I don't know the societal structure."

He walked over to the window and pushed it open. A warm breeze ruffled his wild green hair. Below him spread a vast, immaculately manicured garden, leading out to a dense, ancient-looking forest. There were no skyscrapers. No cell phone towers. No hum of electricity. 

A profound sense of isolation washed over him. The sky was blue, but it wasn't his sky. 

Mom... All Might... Uraraka... Todoroki... Bakugo... 

Izuku gripped the wooden windowsill so hard the wood groaned. Are they still fighting? Did Shigaraki wake up? Are they okay? I have to get back. No matter what, I have to find the source of the anomaly and reverse-engineer it. But until then... I have to survive. And I can't let my guard down.

A sharp, sudden knock at the door pulled him from his thoughts. 

Izuku pivoted, falling perfectly into a martial arts stance. "Come in," he called out, his voice steady and guarded. 

The heavy oak door swung open, and two girls stepped into the room in perfect synchronization. 

Izuku’s analytical eyes swept over them instantly. They were twins, dressed in identical, stylized maid outfits with pristine white frills and black dresses. One had hair the color of spun sugar and pink roses, with a single eye visible, carrying an air of haughty indifference. The other had hair like a clear blue sky, her single visible eye serene but meticulously observant. 

Identical twins. Maids. But their footwork... Izuku's eyes narrowed imperceptibly. They walk heel-to-toe, perfectly silent. Their center of gravity is low. Calluses on the index fingers and palms—weapons training. The blue-haired one’s shoulders are tense, coiled. They aren't just servants. They're security.

"Good morning, esteemed guest," the pink-haired maid said, her voice dripping with a polite but cutting sarcasm. She curtsied flawlessly. "I am Ram, a maid of the Mathers household. It is a miracle you have awoken. I had assumed the barbaric snoring emanating from the adjacent room was a shared trait of your bizarre lineage."

"And I am Rem, the younger sister," the blue-haired maid added, mirroring the curtsy. Her voice was softer, but Izuku’s Danger Sense gave a tiny, almost microscopic twitch. It wasn't an active threat to his life, but a profound, deep-seated suspicion radiating from her towards him. "We have come to assist you in preparing for the day, and to inform you that Lord Mathers requests your presence for breakfast."

Izuku stood up straight, bowing deeply in the traditional Japanese style—a gesture that made the twins blink in mild surprise. 

"Thank you for your hospitality. I am Izuku Midoriya," he said politely. He gestured to his folded costume. "May I ask who cleaned my equipment?"

"Rem took the liberty of laundering your strange garments," Rem replied, her blue eye locked onto his scarred arms with a mixture of curiosity and thinly veiled wariness. "The materials are quite peculiar. They resisted most conventional cleaning spells. And... if I may be so bold, Midoriya-sama, your body bears the marks of extensive, brutal trauma. Was your previous master exceptionally cruel?"

Izuku looked down at his arms. To anyone else, the mangled, twisted flesh looked like the result of medieval torture. How could he explain that he had done this to himself, shattering his own bones over and over again to wield a power meant for a god? 

"I... I wasn't tortured," Izuku said softly, pulling the long sleeves of the white shirt down to his wrists. "These are from my own actions. Mistakes I made while learning to protect others. But thank you for the care you took with my uniform. It means a great deal to me."

Ram scoffed lightly. "A boy who mutilates himself for others. How dreadfully heroic. Do hurry and dress, Midoriya-sama. The half-elf has been anxiously pacing the halls, and the loud one in the atrocious orange garments is already causing a nuisance in the kitchen."

"Natsuki-san is awake?" Izuku asked, relief flooding his chest. At least he wasn't entirely alone. 

"Unfortunately," Ram deadpanned. "He possesses the volume of a banshee and the grace of a drunken earth dragon. We shall wait outside. Please, do not take too long, or Ram will assume you have perished from sheer incompetence."

With another synchronized bow, the twins exited the room, closing the door behind them.

Izuku stood alone for a moment. He quickly stripped off the borrowed sleepwear and slipped back into his freshly cleaned hero costume. The reinforced pants, the utility belt, the iron-soled boots. He slid the metal mouth-guard up around his neck and secured the dark green cowl. Finally, he wrapped Gran Torino’s cape around him. 

He didn't look like a guest. He looked like a soldier ready for war. 

Let's go meet the lord of the manor, Izuku thought, taking a deep breath. 

Navigating the Mathers mansion was like walking through a museum of opulence. The hallways were lined with exquisite tapestries, suits of decorative armor, and massive, arched windows. Izuku walked quietly, his iron soles making no sound against the plush carpet—a stealth technique he had perfected while evading the Pro Heroes during his vigilante stint. 

As he turned a corner, he heard a loud, bombastic laugh that could only belong to one person. 

"And so I told the guy, 'Listen buddy, in my world, we don't need magic to fly! We have metal birds that carry hundreds of people across the sky!'" 

Izuku entered a wide corridor to find Subaru Natsuki enthusiastically gesturing to a bewildered Emilia. Subaru was wearing his trademark black and orange tracksuit, a fresh bandage taped over the bridge of his nose. Emilia was wearing a stunning, elegant dress of white and purple, her silver hair shimmering in the morning light. Puck was floating lazily on her shoulder, grooming his whiskers.

"Midoriya!" Subaru cheered, spotting him. Subaru ran over and clapped Izuku on the shoulder. "My man! The MVP! The boss-slayer! Look at you, suited up and ready to go! Did you sleep well? I slept like a rock! A rock that got punched in the face by a giant, but still!"

Izuku managed a small smile. "I slept fine, Natsuki-san. How is your nose?"

"Healed to perfection, courtesy of Emilia-tan!" Subaru struck a pose, pointing at the half-elf. "Her magic is like a warm, angelic hug for my face!"

Emilia smiled gently, though her amethyst eyes carried a serious weight as she looked at Izuku. "Good morning, Izuku. I want to thank you again for what you did last night. If you hadn't intervened... Subaru and I would have surely perished."

"You don't need to thank me, Emilia-san," Izuku replied earnestly, bowing his head slightly. "Saving people is... it's just what I'm supposed to do. Though, I must apologize for the structural damage I caused to the storehouse."

Puck floated closer, circling Izuku's head. "Structural damage is an understatement, kid. You vaporized a building without a single drop of mana. The Sword Saint is still scratching his head over that one." The spirit paused, hovering right in front of Izuku's eyes. "You're still an empty void. It's so fascinating. I'd love to dissect your Od sometime."

Izuku took a step back, instinctively raising a hand. "I-I'd prefer you didn't dissect anything, Puck-san."

"Come along, you three," Ram's voice echoed from down the hall. She was standing by a set of massive, ornate double doors, her posture rigid. Rem was standing silently beside her. "Lord Roswaal does not appreciate being kept waiting. And Ram does not appreciate her schedule being ruined by lingering."

Emilia took a deep breath, her demeanor shifting from relaxed to regal. "Let's go. Roswaal is... eccentric, but he is my sponsor for the Royal Selection. Please, just be polite."

The double doors swung open, revealing a dining hall that could rival a five-star hotel. A long, mahogany table was set with exquisite silverware and crystal glasses. But Izuku barely registered the room. 

His eyes were locked onto the man sitting at the head of the table. 

Danger Sense didn't scream. It didn't spike with immediate, murderous intent like Elsa’s had. Instead, it hummed with a profound, oppressive weight. It was the feeling of standing next to a dormant volcano, knowing it could erupt at any second. 

The man was tall, exceptionally lean, and dressed in clothing that defied all logic. He wore a jester-like outfit of vibrant purples, pinks, and yellows, complete with a high collar and a flowing cape. But the most striking feature was his face. He wore thick, white clown makeup, with mismatched eyes—one yellow, one blue. 

He looked ridiculous. But Izuku Midoriya knew better than to judge a threat by its costume. 

His posture is completely relaxed, yet there are no openings, Izuku analyzed, his muscles tensing instinctively. The air around him feels thick, almost viscous. It's like the atmospheric pressure is warping. Is he using an emitter-type Quirk constantly? No, it's mana. The energy Puck talked about. This man is a powerhouse.

"Weeeell, nooow," the man sang out, his voice a bizarre, drawn-out lilt that made the hairs on Izuku's arms stand up. "What a faaascinating group of guests we have this mooorning. Please, please, do take a seeeat."

Emilia took a seat near the head of the table. Subaru eagerly sat next to her, completely oblivious to the oppressive aura the man emitted. Izuku chose a seat opposite Subaru, ensuring he had a clear line of sight to the doors, the windows, and the eccentric lord. 

"Allow me to introduce myyyyyself," the man smiled, resting his chin on his hands. "I am Roswaal L. Mathers, the lord of this domain, and the sponsor for Lady Emilia's bid for the throoone. And you must be the brave, mysterious heroes who saved my precious candidate."

"I'm Subaru Natsuki!" Subaru announced proudly. "Just a regular guy who got summoned to save the day!"

Roswaal's mismatched eyes drifted slowly over to Izuku. The yellow and blue irises seemed to pierce right through Izuku's cowl, analyzing the scars, the tension, and the absolute lack of mana. 

"And yooou?" Roswaal purred. "Reinhard sent a rather... frantic bird this morning. He claimed a boy wrapped in green lightning defeated the Bowel Hunter with physical strength alone, generating a shockwave that cleared the slums' fog. Yet, looking at yooou... I sense absolutely nothing. No Od. No magic. An anomaly wrapped in an enigma."

Izuku met the Margrave's gaze. He had stared down the Symbol of Evil. He wasn't going to flinch at a clown. 

"My name is Izuku Midoriya," Izuku said, his voice calm, respectful, but incredibly firm. "I am a Hero-in-training from U.A. High School. Like Natsuki-san, I am not from this world. I was pulled through a spatial warp during a... a battle in my homeland."

The room fell silent. Even Subaru stopped buttering his bread to look at Izuku.

"A battle?" Roswaal tilted his head, his smile remaining fixed. "How intriguing. You call yourself a 'Hero', yet you wear no knight's crest. You wield power, yet possess no mana. Tell me, Midoriya-kun, what kind of world produces a warrior like you?"

Izuku placed his scarred hands on the table. He knew he had to be careful. Information was currency. But he also knew that if he lied, a man like Roswaal would see right through it. 

"I come from Earth, like Subaru," Izuku began carefully. "But a different timeline or reality, perhaps. In my world, magic does not exist. Instead, roughly eighty percent of the global population is born with a unique genetic mutation called a 'Quirk'. Some people can breathe fire. Some can manipulate gravity. Some have the physical attributes of animals."

Emilia gasped softly. "Eighty percent? An entire world of magic users...?"

"They aren't magic," Izuku corrected gently. "They are biological functions. Like a muscle. But... because so many people have power, society had to adapt. Those who use their Quirks to harm others are called Villains. And those who are authorized to use their Quirks to stop them, to protect the public, are a government-sanctioned profession. They are called Heroes."

Rem, standing by the wall, narrowed her eyes. "A profession? You are paid to save lives?"

"Pro Heroes earn a living, yes," Izuku looked at the blue-haired maid. "But for many of us... it's a calling. It's a duty."

Roswaal’s eyes gleamed with intense, predatory interest. "Fascinating. Truuuly fascinating. And what is your 'Quirk', Midoriya-kun? How did you shatter a building without mana?"

Izuku hesitated. The secret of One For All was the most guarded truth in his world. He couldn't tell them it was a transferable power. He couldn't tell them about All For One. 

"My Quirk is called Superpower," Izuku lied smoothly, using his standard cover story. "It is an extreme physical enhancement ability. It allows me to stockpile raw kinetic energy and release it. The lightning you heard about is just the excess energy bleeding off my body."

Roswaal stared at him for a long, agonizing moment. The silence was thick enough to cut with a knife. Izuku’s Danger Sense thrummed a slow, steady beat. 

Then, Roswaal clapped his hands together, breaking the tension instantly. 

"Woonderful! Simply woonderful!" Roswaal laughed. "A warrior from a society of supermen! And you, Subaru-kun, a boy with no power but boundless courage! You both saved Emilia, and for that, the Mathers domain owes you a debt. Name your rewaaard. Gold? Land? A title?"

Subaru’s eyes lit up. He stood up from his chair. "Actually, I don't want money! I want to work here! Let me be a butler! I want to stay close to Emilia-tan and help her win this Royal Selection thing!"

Emilia blushed, looking flustered. "Subaru, you don't have to do that! You're a guest!"

"I insist!" Subaru grinned. 

Roswaal chuckled. "Very weeell. Subaru-kun shall be employed as a servant. And you, Midoriya-kun? Do you also wish to sweep my floors?"

Izuku thought rapidly. He needed a safe haven. He needed food, shelter, and access to a library or magical scholars to research spatial anomalies. But more importantly, his Hero instincts wouldn't let him walk away. Emilia had been targeted by a highly trained assassin. In Izuku's experience, assassins were just pawns. There was a mastermind. There was a 'League of Villains' in this world, and they were hunting this kind girl. 

"I respectfully decline a servant's position," Izuku said, sitting up straighter. The aura of the Vestiges, the sheer, undeniable weight of the ninth wielder of One For All, seemed to bleed into his posture. Even Ram blinked, taken aback by the sudden shift in the boy's presence. "I have no experience as a butler. My skills lie entirely in threat assessment, combat, and civilian protection."

Izuku looked directly into Roswaal's mismatched eyes. 

"Lady Emilia was targeted by a professional killer," Izuku stated, his tone shifting into the analytical cadence he used during strategy meetings with Endeavor and Hawks. "The Bowel Hunter mentioned an employer. That means the threat is ongoing. Your mansion is isolated, making it defensible, but also vulnerable to a siege. You have two maids for security. While I suspect Rem and Ram are highly capable combatants—" the twins both stiffened slightly at being read so easily "—they cannot cover all blind spots 24/7."

Roswaal’s smile vanished, replaced by an expression of sharp, calculating intellect. "Gooo on."

"I ask to be hired as Lady Emilia's personal bodyguard and the estate's security consultant," Izuku offered. "In exchange for room, board, and access to your archives to research a way home, I will provide round-the-clock protection. My Quirk allows me to sense malicious intent. If anyone approaches this mansion with the intent to harm, I will know before they even breach the tree line."

Subaru whistled low. "Damn, Midoriya. You make my butler request sound really lame."

Emilia looked at Izuku, her eyes wide. "Izuku... you don't have to fight my battles. You want to go home to your family. I can't ask you to risk your life for me."

Izuku turned to her, and the stern, soldier-like expression melted away, replaced by the warm, earnest smile of a boy who simply wanted to help. "You aren't asking, Emilia-san. I'm offering. Where I'm from, we don't turn our backs when someone is in danger. Meddling when you don't need to... is the essence of being a Hero."

A profound silence settled over the dining hall. 

Roswaal L. Mathers stared at Izuku Midoriya. For the first time in centuries, the Margrave felt a genuine thrill of the unknown. 

"Agreed," Roswaal said, his voice losing its sing-song quality entirely, settling into a smooth, dangerous baritone. "Izuku Midoriya. You shall be a guest of honor, and the guardian of this estate. Let us see if the 'Hero' of Earth can withstand the demons of Lugunica."

Later that afternoon, while Subaru was suffering through his first torturous lesson in laundry folding under Ram's tyrannical supervision, Izuku found himself wandering the massive, labyrinthine halls of the mansion. 

He was conducting a perimeter check. He had his notebook out, mapping the layout, noting the structural weak points, the lack of modern security cameras, and the potential choke points in the corridors. 

As he walked down the west wing, his Danger Sense gave a bizarre, erratic pulse. It wasn't malice. It was more like... static electricity. A spatial distortion. 

He stopped in front of an unassuming wooden door. To his trained eye, the air around the doorframe seemed to shimmer slightly, like heat waves rising off asphalt. 

A spatial Quirk? A warp gate? Izuku's heart hammered. Could this be a way back?

He reached out and turned the brass handle, pushing the door open. 

He didn't find a closet. He found an impossibly massive library. 

The room was vast, stretching far beyond the physical dimensions of the mansion. Bookshelves towered into the darkness above, packed tightly with ancient, leather-bound tomes. The air smelled of old paper, dust, and ozone. 

Sitting in the center of the room, on a small stepping stool, was a young girl. She wore a lavish, pink frilled dress adorned with ribbons. Her blonde hair was styled into intricate twin drills. She held a heavy book in her lap, her blue eyes glaring at Izuku with an expression of profound irritation. 

"You have quite the nerve, barging into Betty's library without knocking, I suppose," the little girl said, her voice haughty and aristocratic. 

Izuku immediately stepped back, bowing in apology. "I'm so sorry! I was just mapping the mansion, and I noticed a spatial distortion around the doorframe. I didn't mean to intrude on your private space."

The girl blinked, lowering her book slightly. "You noticed the spatial distortion? That is the Door Crossing. It is an advanced application of Yin magic. A commoner shouldn't be able to perceive it, much less track it, in fact."

She closed her book with a snap and stood up. "You are the one Bubby mentioned. The anomaly."

"Bubby?" Izuku asked, confused. 

"Puck, you ignorant boy," she huffed, walking towards him. Her small shoes tapped softly against the wooden floor. "I am Beatrice. The caretaker of the Forbidden Library. And I find your existence incredibly offensive, I suppose."

Izuku sweatdropped. "Offensive? I apologize if my clothes—"

"Not your clothes," Beatrice snapped, stopping a few feet away from him. She raised a small, delicate hand and pointed it directly at his chest. "Your very nature. You are a void in the Od Laguna. To exist in this world without mana is an affront to logic. Let Betty see just how empty you truly are."

Before Izuku could react, Beatrice's hand glowed with a dark, violet light. 

Mana Drain, Beatrice commanded internally. It was a spell designed to siphon the magical energy of anyone she touched or focused on, neutralizing threats instantly. 

The violet light hit Izuku's chest. 

Nothing happened. 

Beatrice frowned. She increased the output. The violet light flared brighter. 

Still, absolutely nothing happened. Izuku just stood there, looking slightly concerned. "Um, Beatrice-san? Are you trying to use a Quirk on me?"

Beatrice’s eyes widened. She wasn't just getting nothing; it was like trying to drink water from an empty stone. But then, as her magical senses reached deeper, past his physical form and into his very soul, the spell backfired violently. 

She didn't find an empty void. She found an ocean. 

Beatrice gasped, stumbling backward as her consciousness was momentarily dragged into the depths of Izuku Midoriya's mind. 

The Forbidden Library vanished. Beatrice found herself floating in a dark, infinite expanse, illuminated by swirling clouds of stardust and vibrant, shifting colors. 

What... what is this place, I suppose? she thought, her aristocratic facade crumbling into pure terror. This isn't a soul. This is a realm.

Suddenly, the stardust parted. 

Looming before her were massive, towering figures. They were made of light and shadow, sitting upon thrones of sheer, raw power. 

She saw a bald man with goggles, radiating kinetic energy. 

She saw a man with jagged scars on his face, his aura crackling with black, volatile whips. 

She saw a massive, hulking man whose very presence felt like an immovable mountain. 

She saw a beautiful woman with dark hair and a cape, floating gently, emanating a warm, maternal, yet terrifying strength. 

There were seven of them. Seven immense, ancient souls, all anchored to the boy standing in front of her. 

And then, the First User—a man with long, white hair and piercing, sorrowful eyes—looked down at Beatrice. He didn't speak. He simply stared, a silent guardian warning an intruder to step away from his successor. 

Get out. 

The sheer pressure of the Vestiges' combined willpower slammed into Beatrice. 

With a shrill shriek, Beatrice was violently ejected from Izuku's mind space. She fell backward onto the floor of the Forbidden Library, panting heavily, her blue eyes wide with absolute, primal horror. 

Izuku rushed forward, dropping to one knee beside her. "Beatrice-san! Are you alright? Did you use too much energy?"

"Don't touch me!" Beatrice screamed, scrambling backward until her back hit a bookshelf. She hugged her knees to her chest, trembling like a leaf. 

She looked at Izuku Midoriya. He looked like a polite, scarred, slightly awkward teenager. But Beatrice now knew the terrifying truth. 

"You..." Beatrice whispered, her voice shaking. "You aren't a human. You aren't a void. You are a vessel. You carry the spirits of ancient monsters inside you, I suppose."

Izuku froze. His emerald eyes widened in shock. She saw them. She actually saw the Vestiges. 

Before Izuku could explain, Beatrice pointed a trembling finger at the door. 

"Get out!" she cried. "Leave Betty's library! You are an anomaly that should not exist! Get out, get out, get out!"

A powerful wave of invisible force slammed into Izuku's chest. He didn't fight it, not wanting to harm the terrified girl. He allowed himself to be thrown backward, skidding through the doorway and out into the hallway. 

The wooden door slammed shut with a thunderous BANG. 

Izuku stood in the quiet hallway, staring at the closed door. He slowly placed a hand over his heart, feeling the steady, rhythmic beat beneath his ribs. The Vestiges were quiet, returning to their slumber. 

Magic in this world isn't just physical, Izuku realized, pulling out his notebook and writing with a shaking hand. It interacts directly with the soul. If the villains in this world can target the soul... I need to be more careful than ever.

Deep within the hidden, soundproof study of the Mathers mansion, lit only by the flickering glow of a single candle, Roswaal L. Mathers sat at his grand desk. 

The clown makeup seemed stark and terrifying in the shadows. His usual eccentric smile was entirely absent. His face was a mask of cold, calculating obsession. 

Resting on the desk before him was a book. It was ancient, bound in black leather, radiating an aura of profound, unnatural magic. This was his Gospel—a flawed, yet potent copy of the Tome of Wisdom. It was the script of the world, detailing the exact path of the future he needed to follow to achieve his ultimate, singular desire: the resurrection of Echidna, the Witch of Greed. 

Everything had been going according to the script. Emilia had been targeted. A boy named Subaru Natsuki had been summoned to save her, bound by a power that the Gospel vaguely hinted at. 

But Roswaal slowly turned the worn parchment pages of the book, his mismatched eyes scanning the cryptic text. 

Subaru Natsuki arrives. The Bowel Hunter strikes. Emilia survives. 

The script remained. But the details were blurring. 

Roswaal ran a gloved finger over a section of text that was aggressively rewriting itself, the ink bleeding and morphing into unrecognizable shapes. 

There was no mention of a boy in green. There was no mention of a shockwave that leveled the slums. There was no mention of a quirkless, mana-less vessel housing the strength of an army. 

Izuku Midoriya did not exist in the Tome of Wisdom. 

"An anomaly," Roswaal whispered to the empty room, his voice devoid of its usual lilt. 

A variable outside the script was incredibly dangerous. It could derail centuries of meticulous planning. By all logic, Roswaal should eliminate the boy tonight while he slept. 

But Roswaal remembered the absolute, unshakeable conviction in the boy's eyes at the dinner table. He remembered the reports of a power that could shatter buildings without a single incantation. 

If this 'Hero' could be manipulated... if that monstrous, unrecorded power could be harnessed for his own goals... 

Roswaal's lips curled into a slow, chilling smile. 

"Let us see, Midoriya Izuku," the Margrave whispered, closing the Gospel with a heavy thud. "Let us see if your heroic heart can survive the cruelty of my script. Or if you will break, like all the rest."
