“What a stupid way to die, Kirishima,” A light-haired teen with light pinkish-purple highlights complained in a monotone voice. 

The blue-haired teen glared and growled at the teen beside him, “You’re going to die, too, dumbass!” he roared, smacking the other teen at the back of his head with his activated quirk.

The other teen winced and touched the back of his head, “Ow…” he whimpered, glaring back at Kirishima, “Go to hell.” 

“And leave you here all alone?” Kirishima retorted, rolling his eyes.

Before the light-haired teen could speak in return, the villain in front of them roared in rage, “DO YOU THINK SO LOWLY OF ME THAT YOU DON’T EVEN SEE ME AS A THREAT?!” he growled, activating his quirk directed to the teens.

A giant black hole started forming at his palms, the wind sucking them in ever so slightly. 

“Not really, I just find you troublesome,” the light-haired teen monotone, resting his chin on his palm with his other hand gripping on a loose metal from a fallen concrete, “Katsuki was supposed to end you earlier, but he was too useless that he can’t even do that right,” he answered, glancing at the quiet black-haired teen behind him. 

Katsuki flinched at his words, gripping the hem of his hero costume with tears threatening to fall from his eyes, “I’m sorry–”

“ENOUGH! IF YOU WON’T TAKE ME SERIOUSLY THEN DIE!” The villain roared and powered his quirk, throwing the black hole in their direction at a lightning speed before they could even react.

A dual-haired teen giggled, jumping between the black hole and the other teens in the last second. 

—

“Deku! Hurry the fuck up and open the door!” Bakugou Katsuki yelled while holding the bag of groceries they just bought. 

“Hold on,” Izuku sighed, holding the groceries with one hand and the other struggling to open the door. It took him a few seconds before the door budge and open. 

“Fucking finally!” the blonde teen huffed, entering their dorm with Izuku following suit.

“We’re back!”

Their classmates immediately glance in the doorway and stopped from whatever they were doing to help them with groceries.

“Welcome back!”

“I hope you didn’t run into villains this time.”

“Oh! My! God! Thank you for buying sweets!”

“Poptarts too!"

“Bakugou, Midoriya, you should refrain from buying groceries that are not on the list—”

“Shut up, Four-eyes!” 

Izuku smiled warily and sweatdropped, “It’s alright, Iida. We bought it with our own money, anyway, it’s for everyone,” he explained.

The robotic teen nodded with his hands moving up and down like a robot, “Alright, if you say so, Midoriya!” 

Izuku nodded and smiled, “Oka–”

He was brutally cut off when a black portal appeared in their ceiling and four figures fell with smokes surrounding them.

Class 1-A was immediately on alert, taking on both offensive and defensive stances.

“Is it the league?!”

“How did they get here?!”

“Iida, call Aizawa-sensei!” 

“I’m on my way! Please don’t engage in combat!”

With that, their class president left.

Izuku glared at the four figures, taking an offensive stance as well. He has to protect his friends and get away from here as soon as possible. But they were on UA property, who knows what these intruders will do once they leave them alone.

He just hopes that Iida gets the pro-heroes on time.

They waited for the smoke to clear, holding their breath while surrounding the four figures. 

“Ow… Kirishima, you’re heavy.” A whiny voice complained, “Get off.”

Kirishima? The class thought, their brows furrowed.

The red-haired teen himself blinked in confusion, Me?

“Oh, you’re still alive,” another one spoke, their voice husky and sarcastic.

“You sound so disappointed, I might think you hate me.”

“I do. Fuck yourself.” 

“Sweet, but you really should come up with new insults, dinosaur-shit.” 

“G-guys! W-we shouldn’t be fighting…” another voice spoke up, their voice raspy but quiet. 

“Cool! Guys, we’re not dead!” another one voiced in glee, their giggles filling the room.

“Why the hell are you even here?”

Finally, the smoke cleared up.

A blue-haired teen with his hair down showed up first, wearing a blue hero costume relatively close with the canon Kirishima’s hero suit. 

Another teen appeared next amidst the smoke, they have a dual-haired color with black and blue split perfectly in the middle. He was wearing UA’s gym uniform with other accessories on his clothes. 

“Kirishima?!”

“Me?!”

“Todoroki without a scar?!”

“...What?”

The class roared in confusion, staring at the two intruders with wide eyes open. Some rubbed their eyes, pinched their cheeks, punched themselves, and whatever whatnots to prove themselves that they weren’t seeing a hallucination. 

Todoroki and Kirishima look baffled by the sudden appearance of their look-a-likes with different color themes.

“Alright, I don’t get enough sleep to give a fuck on what’s happening here.” Shinsou stood up and walked away with a cat mug in his hand, leaving their class stunned.

(TO make this easier, the canon characters’ names are written normally. While the inverted characters have “I.” written before their names.)

I.Kirishima frowned from the sudden commotion, finally noticing the people surrounding them. He immediately activated his hardening quirk in case of combat before analyzing the people in the room. 

To his surprise, they all looked too familiar.

His eyes flickered, recognizing some of them just a little… different.

“Wow!” I.Todoroki gasped, scrambling towards his look-a-like with an exaggerated smile, “You look just like me! But with trauma!” he giggled, holding Todoroki’s hands and shaking them up and down.

“No offense though! You just need to brighten up your life more!” the teen added with a cat-like grin on his lips.

Todoroki took a step back, taking sharp breathes from the sudden interaction before glaring at his look-a-like, “Who are you–”

“Oh! You have a nasty scar! That's pretty ugly!” I.Todoroki chuckled, tilting his head ever so slightly, “I’m so glad I’m not you!” 

The class was dumbfounded, not sure how to take in the situation. They were frozen in place, watching the weird interaction between the two Todorokis in the room.

The newcomer that looked too much like Todorki just insulted Todoroki backhandedly, one of the most handsome students in their class and the school by far.

Izuku gulped, itching for answers finally breaking the silence from his class, “Who are you guys? Why are you here? How did you get here?” he blurted out, taking the attention from the intruders.

I.Kirishima eyed him with a raised eyebrow, analyzing him inside-out making the poor teen uncomfortable.

The teen sighed, rolling his eyes as if he just realized something. “Not another one,” he groaned, ruffling his hair in annoyance.

“Another one?” Izuku asked, tilting his head in confusion, “What does that mean–”

“Ah, you must be me,” A monotone voice spoke up.

Their heads immediately turned to the light-haired teen wearing a hero costume similar to Izuku’s, except it was the color of between purple and magenta with white lines. 

“Me…?” Izuku sucked in his breath, scanning his look-a-like.

The newcomer has freckles similar to his, bright blue shoes vaguely similar to his shoes, and a—

I.Izuku sighed and turned around to face another teen, ignoring the questioning looks from the people around him when he heard a meek muttering behind him. “Katsuki, how long are you going to sit there?” he snarled weakly, but loud enough to instill fear into the black-haired teen still sitting on the floor with his knees on his chest. 

I.Katsuki looked up, meeting I.Izuku’s impassive and apathetic look that made him flinch. He doesn’t like that look, he never liked that look. He can never read I.Izuku whenever he’s like that, he'll– 

“I-I’m sorry!” he cried, getting out of his head before scrambling on his feet to stand up besides I.Izuku. 

“WHAT IS THE FUCKER APOLOGIZING FOR?!” Katsuki yelled across the room, finally connecting something dot to dot. 

I.Katsuki quivered and hid behind I.Izuku, tears dripping from his eyes, “I’m sorry, I d-didn’t mean to–” 

“WHAT THE HELL–”

“You’re such a crybaby, Katsuki,” I.Kirishima intervented, ignoring the explosive teen and glaring lowly at the quivering black-haired teen instead, “You’re embarrassing us from us, ” he grunted.

I.Katsuki nodded and pursed his lips, holding onto I.Izuku’s costume, “I didn’t mean to…” he muttered weakly, looking down with newly formed tears flowing down his cheeks.

“Hey! Don’t talk him down like that!” Kirishima finally spoke, taking the blue-haired teen’s attention away from the black-haired teen. “That’s not very manly!”

Ah, must be me.  I.Kirishima thought.

I.Kirishima shook his head from his look-a-like and waved his hand off, “Doesn’t matter,” he huffed before turning his attention to the class. 

I.Todorki was beside him at his right giggling to himself, I.Izuku on his left with an impassive look on his face, and I.Katsuki behind them holding onto Izuku’s costume like his life depended on it. 

He took a step forward and bowed with his hand on his chest, “Greetings, I am Kirishima Eijiro,” he started and stood up straight, a smile growing on his lips as he notice everyone hold their breath, “And it seems like we’re brought onto your dimension.” 

As if on cue, All Might barge in their dorm.

“HAVE NO FEAR, STUDENTS! I AM HERE!” All Might boomed, now standing in front of Aizawa and the rest.

“I will—” the number one hero stopped midway from his sentence when he was pulled in by a force coming from his successor’s look-a-like. Baffled, he turned to the boy, “What–”

“All Might!” the students screeched, witnessing the dreaded hostage situation of the number one hero in front of them.

I.Kirishima’s quirk activated with his hand pointed directly at the hero’s neck. His other hand holding the hero’s arm to refrain him from moving. He was glaring at the hero, ready to cut off his limbs with his hardening quirk acting as a sharp knife. “Move and I’ll slash your neck, asshole.” the teen threatened.

I.Todoroki covered the hero’s lower legs in place with ice and his hand igniting blue fire dangerously near the hero’s face, a smile still stretched on his lips. His smile was mischievous, yet still holds the killing intent he was radiating.

I.Katsuki was no longer quivering, he was on top of the hero in a swift motion while grabbing a fistful of hair and his legs in the pro-heroes shoulder to remain in place. His other hand popping sparks as a warning, his eyes empty and his cheeks stained with tears. 

Izuku activated his quirk, green lightning spreading from his body, ready to jump in the situation. Kirishima activated his quirk, along with Bakugou, Todoroki, and the rest of the class to engage in combat.

"Let our teacher go!"

"Don't engage in combat!" Their teacher yelled along with pro-heroes with their quirks pre-activated, glaring at his students, especially towards his problem child.

The students looked at their homeroom teacher with pleading eyes, "But-"

"No buts!" their teacher snapped.

The students gritted their teeth, their hands growing pale from gripping their hands. They looked at the situation at hand, forcing themselves to watch the situation helplessly. 

I.Izuku stared at the number one hero before looking back from the crowd.

Aizawa was using his quirk on I.Izuku if his glowing eyes and floating hair were any indications. The teacher glared in their direction, especially towards the light-haired teen, “Let him go," the pro-hero ordered, but the intruders didn't reply. They didn't budge.

"What do you want?” he asked, trying to remain calm about the situation, trying to take another approach.

They can't engage in combat easily, not with the number one hero as a hostage and the kids in their field of combat.

I.Izuku opened his mouth, his face stoic and his voice in monotone.

What left his lips next stunned them.

“We want to know why you have the number one supervillain with you.” 

Chapter Text

“We want to know why you have the number one supervillain with you.” I.Izuku monotone, his pale fingertips gesturing at the hero in their hands. 

The crowd was dumbfounded by the sudden remark.

I.Kirishima scanned the room with his quirk still active near the hero’s neck.

Everyone was frozen in place. Some were terrified, stunned, furious, and had the look of helplessness. The class wasn’t good at hiding their thoughts and expressions.

They’re going to get themselves killed if they’re easy to read like that. He thought, mildly disappointed at their counterparts. The thought caused his heart to ache from the familiarity, but he shook the feeling off. 

The students were trying their hardest to refrain from using their quirks. The heroes were alert; glaring daggers in their direction with their offensive stances.

He would’ve laughed if they were in a different situation, but the situation right now was no laughing matter. The situation is too ironic, he thought.

He doesn’t know why the number one supervillain was with their look-a-likes if they were in UA, he assumed from the similar scenery of their dormitory.  

He clicked his tongue, ‘We’re in real trouble if our other halves are villains though.’ 

“Supervillain?” Izuku’s frowned, “All Might’s not a villain, he’s the number one hero.” 

“Yeah! Let him go!”

“Let our teacher go!”

“How can he be a villain when he’s the number one hero anyways?!”

“I agree! This behavior is unbecoming of heroes-in-training such as yourselves!”

The class erupted with the pro-heroes trying to calm them down.

I.Kirishima blinked and shakes his head, turning his attention to his white-haired companion, “I just did not hear that bullshit coming from their mouths, please tell me I’m hearing that shit wrong,” he pleaded. 

There was no way that One For All, the person who killed their peers, injured their mentors beyond repair, and the person who broke them into pieces in their countless battles, left them to pick the pieces the asshole left , was the number one hero in this dimension. 

“But it’s true!” 

He looked at the brown-haired girl and raised an eyebrow, the girl looking too familiar with their Uraraka from their dimension, “You must be Ochako Uraraka, no?” he asked.

The girl nodded quickly, “I am! And we’re telling the truth, so please let All Might go,” the poor girl begged. Her eyes were pleading and her teeth gritted in anticipation. 

“Wow! Uraraka begged, I never saw that before!” I.Todoroki chimed in, “I might never see that again, but still!” he added making the poor girl quirk her eyebrows in confusion.

“They’re saying the truth, young ones! I am All Might, the symbol of peace!” the hero in their grasp beamed, laughing as if he wasn’t being threatened by four hero-in-training teens from another dimension. 

I.Izuku raised his brow, his eyes suspecting the hero’s whole being, analyzing him inside-out carefully. Finding holes that may imply that the hero was lying is no easy feat, after all. Especially with their peers that specialized in lying and deceiving people around them. Trust and emotions, after all, were fickle little things.

However, the people here were open as an open book, too open for his liking. 

“He’s not lying,” he finally announced. 

“Figures,” I.Kirishima huffed. 

The three immediately lets go of the number one hero, deactivating their quirks quickly as they appeared earlier. 

The students sighed in relief, their shoulders slumped with the tension leaving their shoulders. The pro heroes, however, were still on guard. 

I.Katsuki jumped off from the hero’s shoulder, muttering anxious apologies as he settles down. Quivering once again and clutching the hem of his hero costume.

I.Todoroki only hummed to himself as he melts the ice in the hero’s legs, “What a twist! Who would’ve thought that the bastard is a hero in this world!” he grinned, clapping his hands in astonishment. 

All Might winced, “What do you mean by bastard, young man?” he questioned.

I.Kirishima snickered from the crowd’s confused faces, “I meant what I said earlier, I told you that we’re more or less brought into your dimension,” he said and pointed at his three companions before pointing at himself, “That means that we’re not from here and the shit we go through might be a little different.” 

“What does that mean?” the girl with black hair tied in a high ponytail frowned. 

He was about to speak when I.Izuku sighed and glanced to the side where the class stood. 

He took a deep breath and glared ever-so-slightly at their counterparts, clearly getting impatient with the idiots around them. “We just explained the gist of it. What can’t you understand about us coming from another world?” he grumbled, clicking his tongue in annoyance. 

I.Kirishima smirked at the other teen’s bitter expression. It’s not everyday that they get a reaction from the white-haired teen aside from his whiny yet impassive personality. 

“So you’re really me! ” the red-haired teen grinned in amusement while pointing towards him.

He rose his brow, not quite sure if he’s supposed to feel happy or disappointed about his counterpart. He wasn’t expressive with his true emotions, which makes him hard to fight against. He may be snarky but it was a form of distraction for the others.

His counterpart, on the other hand, was the complete opposite .

“Woah! Really?!”

“That’s so cool!”

“It’s like having a twin, so cool!”

“WHY IS MINE SUCH A FUCKING WIMP?!”

“Kaachan!”

“Now, now, everyone,” A small figure appeared behind Aizawa, “Let’s all settle down, it appears that our guests do not impose a threat to us, why not continue this conversation in my office?” the White– Mouse? Bear? Spoke. 

“Cool! You have your own psychopath too!” I.Todoroki gushed out.

The school principal only cackled at the remark, “It seems that you know me already, so I won’t waste more time on introductions,” the principal grinned, “Come now, let’s discuss the matter at hand. Follow me,” the rat turned around and left the dormitory.

The pro-heroes were dumbfounded, as well as the class. 

The four figures followed the rat without question.

Kirishima glanced at his counterpart before leaving the dorm. He’s going to need to talk to the guy, after all. 

—

“Now, I’m assuming you’re Midoriya, Todoroki, Bakugou, and Kirishima, correct?” Nedzu questioned before taking a sip from his tea.

They were now in his office. Aizawa and All Might were behind the teens for safety measures if ever the teens try to act out on their own. 

I.Izuku was sitting down on one of the couches in the principal’s office. His eyes were empty and his lips were in a thin line. The teen was clearly disinterested in what’s currently happening, the principal assumes. It was as if the teen accepted life as it is. Quite relatable, one might say.

The blank teen replied, “Right.”

I.Todoroki was looking around the office in amusement. Glitters were in his eyes, observing the furniture and frames attached to the walls. “Cool, I don’t know who’s the painter but they’re pretty good!” 

Nedzu settled his teacup down, a curious smile stretched to his face. “I’m quite curious, how did you get here? Appearing directly at Class 1-A’s dormitory nonetheless.” 

I.Kirishima, who was sitting at the edge of the couch spoke, “We were fighting One For All’s minions, or well, one of his former minions,” he said cooly, watching the mentioned hero flinch. 

“Would you please elaborate? How did the battle turn out?” Nedzu mused. 

I.Todorki’s ears perked and in an instant, he was standing in front of the principal with his hands slammed on the table, “Oh! I can tell you that part!” he beamed, the principal nodding for him to continue.

“So you see, we were fighting the bastard’s minions because the bastard wants to take over Japan and then the world. We’re heroes-in-training so of course, we have to stop him!” he grinned before his eyes glowed with anger and so much killing intent that made Aizawa shiver. 

No student– No, no child should ever radiate that kind of killing intent, even if they were training to be a hero. What kind of living environment do these kids have to be like that? 

“Of course, to avenge our fallen comrades too,” the teen added, the enthusiasm leaving his voice in exchange with a spiteful tone. 

The room went cold. The teachers were not quite sure if it’s the young teen’s quirk at work or just the heavy atmosphere in the air. Nonetheless, they took immediate notice when the teens clicked their tongue, avoided eye contact with furious and solemn looks on their faces. 

I.Katsuki, for one, was starting to tear up again and grit his teeth as if he was reminded of something. This caught the heroes’ interest. “He killed them…” the said teen muttered weakly, looking down with his hands pressed at his knees. His hands were growing pale, but he didn’t care. 

“Bakugou,” Aizawa called, but he didn’t mind him.

When blood dripped from his palms, his nails digging deeper just to distract himself from the memories flashing before his eyes just like it was yesterday, he didn’t care. 

—

"Hey! Who made Bakugou cry  like shit again?!"

"He was cutting onions, stupid! Of course, he'd be crying!"

"There, there. Here, a napkin for your tears and snots. We don't want that in our dinner tonight."

"Mineta! You're making him cry harder!"

"But I was only being a gentleman!"

I.Katsuki laughed, wiping the tears from his cheeks with the napkin he was given, "I'm fine, guys." he assured them.

The class smiled back, others scoffed but he was used to it. 

—

He misses it.

Their smiles, their jokes, their times together; he remembered all of them. He remembered all of it that he wishes he could just die. 

All Might frowns and grabbed the teen’s shoulder, “Young Bakugou, what do you mean by that—”

I.Katsuki abruptly stood up, pushing away the hero’s hand away from him, he felt disgusted by being touched by the said hero. “You bastard killed them before we could even react!” he lashed out, glaring daggers at the pro-hero with tears flowing down his cheeks. “We were still students back then, we can’t fucking defend ourselves just yet and it’s so– It’s not fair– I– “ he choked, falling into his knees in defeat. “We were so hopeless!” he cried out.

The teen's cries rang around the office. Silence took over with his cries only heard. 

All Might’s body grew cold. He wasn’t seeing the full picture, but he understood enough that his counterpart had killed people they care about dearly. He knew that he never did such a thing, not in this universe, no– But he still did it in another. He bowed his head in shame, “I’m sorry, young Bakugou.”

The said teen just kept crying, the pain in his voice so heart-aching that they could not help but feel pity for the boy. As well as for the other teens who remained quiet from the sudden outburst.

Aizawa remained quiet, he could sympathize with the kid. He wasn’t quite sure who are the people that their villain killed, but he has a hunch. 

The kid was suffering, not physically but mentally. But it seems that the mental torture might as well hurt as much as physical pain. They were used to their Bakugou being loud and obnoxious but never have they seen this kind of Bakugou that looked so broken, an exception to the time he broke down about being All Might’s downfall. 

I.Kirishima grumbled and pulled I.Katsuki from the floor back to the couch, the sobbing teen clutching onto his clothes desperately, afraid that he was going to be gone too. I.Kirishima scoffed, placing an arm around I.Katsuki for a sense of comfort, "You're such a crybaby," he muttered.

I.Todoroki sat in front of them, crossing his legs comfortably to take a closer look at the black-haired teen. He placed his hand on the crying teen’s lap, refusing to say another word. His face was now solemn, but somehow blank. 

Nedzu’s eyes softened from the small interaction before eyeing the other teen who hasn’t yet made a move to comfort their crying companion. 

I.Izuku pursed his lips as he glances at I.Katsuki, his eyes flickered with emotions. But the emotions in his eyes disappeared as quickly it appeared, he sighed. “Continuing with the story, we defeated his minions, but only one remained.” he started. 

The heroes’ attention turned to him. 

“That person has a quirk that ables him to bring other people into other dimensions, I assume. He was the only one remaining so we let our guards down, and besides, we thought he would flee already since he’s the only one left.” 

“But obviously we were wrong, we were too tired to fight. The adrenaline in our veins stopped the moment we let our guards down. Some of our peers are already down so no one can really move to fight the villain,” he breathed out, “And I don’t even know if they’re already dead or not to even help us.”

Nedzu nodded, “If you don’t mind, who are these peers that you talk of?”

I.Izuku’s eyes flickered once again, this time, his emotion was more evident, “In this dimension, it’s only year 2XXX, right?” he asked.

“Correct.” the principal answered. 

“Then we’re a year ahead of you,” he muttered.

Aizawa’s brows furrowed, “What does the year have to do with that?” 

I.Izuku played with his fingers before muttering, “You still have time to save your students from dying then,” he answered solemnly, pain flashing before his eyes.

Aizawa’s eyes twitched, his hunch was right. He didn’t like that he was right. He gritted his teeth, his hands clutched into a fist into his sides. A year from now, his students may suffer the same fate as these kids went through. He couldn't even imagine— No, he was already seeing it. How much these kids broke from losing their friends, the pain they've dealt, and the burden they carry.

“If your peers are the same ones as our students in Class 1-A, how come you were indifferent with the class here upon meeting them?” Nedzu asked. 

A broken smile made it’s way up to I.Izuku’s lips, a lone tear falling down his cheek before quickly wiping it away. “Because we’re not stupid, and we’re not that delusional either,” he said before letting out a weak laugh.

“They’re not our friends, ours are already gone.”
