Heyo, everybody! Welcome to my first full length Hero Academia story (also I guess it's my first Devilman story as well)! This story was partly inspired by "The Immortal Hero" by QuirkQuartz (check it out, my dudes), an IzuMina fanfic that crosses over with Ajin: Demi-Human (which you should most definitely ALSO check out if you haven't already). I've been wanting to do a MHA story ever since I first started watching the show, but no idea seemed to click with me. That is, until I randomly thought to myself while partaking in a light snack consisting of burritos and french fries, "Hey, what if demons existed in MHA?"

And that's the amazing origin story of this fanfiction. Amazing, right? Anyway, I won't bore you any longer with my incoherent rambling, on with the story! I hope you all enjoy this first chapter!

...

Not everyone was born equal, that was just the hard truth of the world. Even if you were born with a quirk, there was no certainty that it would be of much use. Super strength? It had many uses: heavy lifting, paid protection, security, hero work...Some people would kill for that kind of power. Some people have killed with that power.

Being able to pull your eyes out of your sockets? Good luck making a career out of that! You couldn't even make your living as an oddity in the circus, a man with empty eye sockets blended in pretty well in a crowd full of horns, fangs, fur, tails, and any number of abnormal traits.

But sometimes, life carelessly tossed you into the bottom of the barrel, a mackerel floating lifelessly, buried beneath its kin. Rotting away, never to be touched, seen...Never to be heard crying for help.

In a world full of quirks, the quirkless suffered. To be normal was to be seen as an outcast, a black sheep. You were cast away, everyone looked down on you, at least at first. Eventually, people stop caring. The passing glances they give you are somehow even worse than the hateful glares. When someone looked at you with disgust, it hurt...but at least you knew you existed at that moment. But when the world passes you by like you're a boring bug they almost accidentally stepped on, it took its toll on your mind...

Izuku Midoriya was always that quirkless young boy who never existed. It was part of the reason he still tried to interact with Katsuki "Kacchan" Bakugo, despite his bullying and tormenting, because at least he existed in that boy's life. But other than his so-called "friend", he had no one. And the worst part is that he got used to it. Blending in with the crowd became routine, a specialty. Maybe he should've been born with an invisibility quirk, would've made life a lot easier...

Meaningless, Quirkless "Deku", as he was known by. An ordinary kid with no extraordinary gifts. Just a collection of notebooks filled with unfulfilled dreams. He was convinced this was to be his life forever.

So why the fuck was this happening?!

Izuku barely dodged the blow, tripping over his own two feet and face planting into the rough concrete. He groaned in pain, and scrambled to his feet as panic took over. 'Run!' he ordered himself. 'Run, dammit! Before you get killed!'

His feet wouldn't move. He was stuck in place!

"H-H-HELP!" he managed to cry out. "S-S-SOMEONE HELP ME!"

No one was coming to save him, he realized. He was on his own. Why was he so stupid?! Why had he agreed to come here?! WHAT THE HELL WAS GOING ON?!

Memories of the events leading up to him flashed before his mind, and he found himself collapsing on his knees, bile threatening to burst from his throat. 'No way...' he whimpered. 'This isn't happening, this CAN'T be happening!'

The blood, the screams...

The thrill.

'Mina...'

The dust cleared, revealing the hulking figure that had just tried to kill him. The man rose, his two blonde sprigs of hair poking out. His muscles bulged in a way no one else's could, because this wasn't an ordinary person who had attacked him.

This was wrong though...where was the smile? Why wasn't he smiling?

Cold blue eyes cut through Izuku's heart, and he felt a warm liquid run down his legs, darkening his pants.

"Damn demon," the man swore, clenching his fists. He gestured towards the concrete clearing behind him. "Was this YOUR doing?! Did you kill these people?!"

Izuku's mouth moved, but no sound came out.

"And to add insult to injury," the man continued, "you disguise yourself as a child...Have you no shame?!"

The man braced himself, as if he were preparing to perform a full sprint towards the young middle-schooler. "Forgive me, young man," he growled. "Though it pains me to say it, this is the only way to save you! Perhaps you'll find peace in another life..."

The blue eyes blazed with righteous fury.

"...ONCE I PURGE THE MONSTER WITHIN YOU!"

...

The Previous Day...

...

Another ordinary day, another meaningless blip on the world's radar.

While the debut of Mt. Lady was quite stunning, and he had made sure to include it in his notes, Izuku Midoriya just wasn't feeling too keen. He had woken up on the wrong side of the bed, even though he had nothing to be upset about. Honestly, everything was okay, but since Izuku had woken up feeling like total crap, it was no longer okay. It was..mediocre. Yes, mediocre at best.

Standing in front of his junior high, Izuku felt hesitant to enter. This was a common occurrence, every day was just a little harder than the last, if he were to be completely honest with himself. The building loomed over the small, nervous boy, overpowering him with the sheer magnitude of itself. In truth, the middle school was one of the lowest ranking in the country, but Izuku was never concerned with that. As far as he knew, he was simply the lowest ranking of the pack.

He wondered how he would be treated by his classmates this time...They would most likely ignore him, as per usual, at least until homeroom. That's the one class he had with Kacchan, and the Explosion-user ran that small room with an iron fist. He was the boss, whether his classmates liked it or not. It was scary, how someone so scorned by his classmates could still rally them towards a common goal; that goal was making Izuku's time spent in there a living hell.

Taking a deep breath, Izuku walked through the school gates. 'Just get through the day, Izuku...' he told himself. 'It'll be over before you know it.'

The day passed by uneventfully, just like every other day. Izuku kept to himself, occasionally glancing at his phone to check the latest hero news. Mt. Lady's debut was blowing up crazy fast, she already had a dedicated fanbase. Though, Izuku had a feeling they weren't praising her for her hero work...

One story, however, gave him pause, and after a moment of consideration he clicked on the article.

'Serial Murders Rise Into Dozens, Suspect Still at Large'

Apparently, the victims had been found simply...torn apart. As if they were fought over by two wolves like a piece of meat. This wasn't unfamiliar news, and Izuku had admittedly visited forums dedicated to the mystery of the murders. People were comparing the killings to the death row inmate 'Moonfish', a villain whose quirk turned his teeth into deadly blades. Some said it was possibly the result of a crazed lunatic with an insanely strong strength enhancer quirk, but many disagreed.

The victims were always too...shredded.

"Hey, did you hear about the Sabbath Parties?"

Izuku perked his head up, glancing towards a desk a few feet to his right, where two of his classmates were having a hushed discussion.

"Sabbath?" one of them asked. "The hell's a 'Sabbath'?"

"It's crazy, man!" the first student exclaimed, throwing his hands into the air. "Apparently it's some weird Satanic shit disguised as a rave, you know? Police have been cracking down on these things for months!"

"Oh yeah, I remember those!" a third classmate joined in on the conversation. "I hear you get some reeeeally good drugs there!"

"Dude, is that ALL you ever talk about?"

"Fuck yeah, man!"

One of the boys leaned in real close, and despite his better judgement Izuku strained to hear.

"I heard that people get murdered at those parties..."

"What? No way! Why would they do that?"

One of them shrugged. "I don't know, maybe they, like, wanted to summon a demon or something."

He was immediately socked in the head by his buddy. "Idiot, demons aren't real!"

"You know what else I heard, guys?" A pause. "Apparently a pro hero was seen at one of those parties, when he came back...he changed, dude!"

"Changed? What do ya mean?"

"I don't know, but people say he's, like, totally different now! In, like, a REALLY weird way!"

At this point, Izuku returned his attention back to his phone, deciding that he had heard far more than enough. It wasn't his business, anyway...

Demons, huh? That was another common theory among the serial murder forums. Demons...those ancient monsters from folklore that terrorize humans for all sorts of varying reasons. Some history buffs claimed that the murders matched several old cases from way back when that were attributed with 'demons'...though back then everyone were quirkless religious fanatics. Nowadays demons were underground rumors few people whispered, and Izuku could see why. The thought of a terrifying monster hiding in the shadows, waiting for the perfect moment to take you away and do God knows what...

It was horrific.

But no, those were baseless rumors. Now that everyone, or almost everyone, had superpowers of their own, these murders could be easily explained. It wouldn't be too hard to imagine a maniac with a quirk that tore people apart when used on them...

"Ah...Midoriya, you're also planning to apply for U.A., yes?" the teacher inquired, suddenly bringing Izuku back to reality.

There was silence for the briefest moments, before the whole room exploded with horrible laughter. Izuku felt his face go red, and he glanced down at his lap, not wanting to meet his classmates' eyes...or let them see the tears beginning to form in his own.

Of course, he should've expected this result a mile away, and he did. The news had simply distracted him...

"Izuku?! In U.A.?! No way!"

"Like he could ever be a hero!"

"U.A. is the toughest school out there! He'll never make it!"

"Besides, he's gotta have a quirk to apply!"

"A-Actually, they got rid of that rule..." Izuku meekly tried to inform his classmates, awkwardly twiddling his thumbs. "A-And because of that, I thought...I thought I could at least try-"

"You're so full of shit, Deku!" this one came from Kacchan, who had planted himself in front of Izuku's desk, spreading his arms wide to show off the small explosions created by his quirk. "You damn idiot, you quirkless bastard!"

Izuku shrank further into his seat, trying his best to repeat his mantra to himself. 'Deep breath...count to ten...deep breath, count to ten...'

It wasn't working.

"You really think they'd let someone like YOU in when they could have someone like ME?!" Kacchan roared, sneering down at the timid, quirkless student. "That's fucking rich! Listen up, Deku! I'm the only one in this crappy school WORTHY to attend U.A., GOT THAT?! You're not even worthy enough to kiss my fucking ass!"

The teacher, who had been choosing to ignore the exchange, suddenly glanced up from his papers. "Mister Bakugo, that is enou-"

"Quirkless, worthless Deku!" Kacchan continued to berate. "That's all you'll ever be, got that?!"

"MISTER BAKUGO!"

The classroom's laughter died down, and the students shifted their eyes from Kacchan to the teacher, then back to Kacchan.

Kacchan growled and turned around. "What?" he grunted.

"Sit. Down."

"..." Kacchan shoved his hands in his pockets and trudged back to his desk. "Whatever you say, Teach."

"Thank you, Mister Bakugo..." the teacher sighed. "Now, Midoriya-"

Izuku didn't stop to hear what the teacher was about to say. With tears streaming down his face, he sprinted out of the front door, stunning his classmates.

Bakugo stared after him apathetically.

'Goddammit!' Izuku cursed as he ran out of the school, wiping away his tears with his sleeve. 'God-fucking-dammit!'

Why did he let their words get to him? He had heard them over a million times before, what made today so different? He remembered the looks on each of their faces...the way they sneered and cackled, the way Kacchan's face contorted into something of pure, unrestrained malice.

He couldn't go back.

He wouldn't go back.

That was the final straw! He wasn't going to deal with those kids anymore! He could register in a new school, take a longer train ride...

'Quirkless, worthless Deku...' he thought as he continued to run, pushing past people without even realizing they were there. He wasn't sure how long he had been running, but eventually he stopped.

'Stop acting like this is something new,' he scolded himself. 'Come on, you knew you didn't have a chance from the start...your dream is just that...'

"A dream." he breathed.

Just before he heard the car's horn blare out. Izuku snapped his head up to see a car speeding towards him; he had unknowingly stopped in the middle of the road. And the car wasn't going to stop in time.

Everything slowed down, and Izuku was sure his life was going to end in that moment. Quirkless, worthless...dead Deku.

"Look out!"

He felt someone grasp his arm and yank him away just as the car blazed past, and the two stumbled on top of each other, Izuku on top. He groaned in minor pain, pressing his hand down to stabilize himself and push himself back up.

He touched something very soft...and squishy.

Glancing down, Izuku was face to face with a girl... She was, to be completely honest, breathtakingly beautiful, and Izuku felt his cheeks glow warm. Pink skin and pink, messy hair with two small horns poking out. Hypnotizing black eyes with yellow irises...the girl was exotic.

Wait, why were her cheeks turning lilac?

Izuku's eyes slowly crawled down, and he realized just what he was holding...

Immediately he leaped back and bowed over and over. "I-I-I'm so SORRY!" he frantically apologized, barely able to comprehend anything at this time. "I-I-It was an a-accident, I-I-I SWEAR! I-I promise, I'll m-make things right, j-just name your price!" He dug into his pocket, pulling out some spare change. WHAT?! he only had 500 yen?! Pathetically, he held the money out towards the girl as she slowly rose to her feet while still blushing.

A few moments passed, until the girl suddenly burst into a fit of giggles, leaving poor Izuku looking very confused. "Pfffft, oh my GOD!" she exclaimed, wiping her eyes and clutching her stomach. "No need, dude! T-That silly apology was more than enough to make my day!"

"E-Eh?" Izuku squeaked.

The girl calmed down and shook her head. "I mean, can't say I should be upset," she said with a lopsided grin. "I saved your life, you copped a feel, I say that's a fair deal."

"I-I didn't mean to..."

The girl waved it off. "Trust me, I can tell." She smirked and placed her hands on her hips. "Seriously, dude, calm down. I ain't gonna bite you, I promise. Now put the money away, okay?"

Izuku obeyed and pocketed his money, before gulping and staring at the girl, standing straight and rigid. 'Wow, she's super cute!' he thought. 'Should I say something? What would I even start with?'

"I'm Izuku!" he practically squawked, much to his embarrassment. "I mean..." He cleared his throat. "I-I'm Izuku Midoriya..." He extended his hand towards her.

"Mina Ashido," the pink girl chirped, raising her palm high into the air. "Don't leave me hanging!"

Izuku hesitantly raised his hand, and Mina happily slapped it with her own. "Alright!" she cheered.

'She sure is full of energy.' Izuku noted. "Um...Shouldn't you be in school right now?" he wondered.

"Shouldn't you?" Mina countered with a wink. She chuckled and shook her head. "Yeah, I should...but I felt like playing hooky, you know?"

"Um...I don't..." Izuku answered, scratching the back of his head. "Though that might be because I've never done that..."

"Aren't you doing that right now, Midoriya?" Mina pointed out, tilting her head.

Izuku went silent, and suddenly seemed very interested in his shoes. Mina observed this, and came to the conclusion that whatever it was he was doing...he didn't want to talk about it. She shrugged, then placed her hand on his shoulder. "Hey, you don't have to tell me if you don't want to." She frowned. "Bullies, huh?"

Izuku sniffed and nodded. "Yeah...Thank you, Ah..." He trailed off, not being able to remember her name. He felt himself grow warm again, and he thoughtg, 'Well this is just great!'

"Ashido," Mina replied, smiling gently. She looked her new acquaintance up and down, studying him.

He was nervous as heck, but he was also pretty cute, in a really dorky sort of way...He looked like he hadn't had a good time in forever, and Mina was wondering if she could change that...

"Uh...Ashido?" Izuku called out, growing self-conscious because of the pink girl's staring.

Mina blinked, then grinned widely. "Midoriya, I feel like doing something completely impulsive!" she announced.

Izuku gulped. "H-Huh?"

"When was the last time you went out with friends?" the girl asked suddenly.

"Oh! U-Um..." Thinking about it for a few moments, Izuku glanced away and said, "Uh...when I was four?"

"Okay...wow." Mina deadpanned, before going back to her springy self. "Well it's time to update that number, buddy! I'm inviting you to a party!"

"A...party?" Izuku was beginning to feel uncomfortable, but for some reason, he was beginning to feel intrigued.

"Yup!" Mina chirped. "There's gonna be this cool secret rave thing tonight, you should totally come!"

A rave? Izuku had heard about those...all the people dancing in a large crowd, no free space whatsoever...

"I...I don't know..." Izuku muttered, looking away. "Raves...aren't really my thing, to tell you the truth..."

"Ah..." Mina sighed, but then reached into her pack (which, as a big middle finger to Chekov, was never mentioned until now) and pulled out a pad and pen. She scribbled something down and then tore the sheet off, before handing it to Izuku. "Well, here's the address in case you change your mind," she offered warmly. "It could do you some good, getting out of your shell."

"I..." Izuku cut himself off and nodded. "Right, thank you, Ashido."

Mina leaned in, winked, and shook her head. "It's Mina, and you're welcome."

...

When he eventually returned home, Izuku retreated into his room after a quick greeting to his mom. Throwing his bag into the corner, he pulled out the piece of paper Mina had given him, looking over it over and over. He felt torn.

While it was true that he was a socially awkward hero nerd who didn't stick around in crowds, part of him was yearning to go. He told himself it was because he wanted to forget about what had happened today at school, and that was partially truthful.

But he knew the real reason.

He was totally puppy-crushing on that girl.

And at the end of the day, Izuku was a teenage boy, and teenage boys consistently did everything to spend time with a crush.

"Guess I gotta find something to wear..." he muttered.

Eventually he decided on a green t-shirt with black pants and shoes. It wasn't anything fancy or even casually appealing, but it was the best he had to work with. It wasn't everyday a girl invited him to a party...

...that felt weird just crossing his mind.

Izuku sighed and threw on his hoodie, exiting his room and heading towards the front door. "Mom, I'm going out!" he called over his shoulder.

His mother, Inko Midoriya, poked her head out of the kitchen, looking really confused. "At this time of night?" she wondered.

"A...A friend invited me out..." Izuku said, nodding. "Is...Is that alright?"

Inko hesitated, but then sighed and gave an encouraging smile. "Go get them, sweetie."

Izuku smiled back. "Thanks, Mom. I won't be gone too long!"

...

Finding the warehouse the party was being held at was pretty hard, the building was quite a ways off the beaten path. In the end the address Mina gave him did jack-shit at helping him, and he ended up finding his way by listening to the distant sound of EDM. There was a bouncer at the entrance, an intimidating man with large moose antlers growing out of his head. He glared at Izuku as he passed by, but didn't stop him from entering.

"Not enough meat," he heard the bouncer muttering to himself. "Just skin and bones..."

That set Izuku on edge, but that was quickly overwhelmed by the sheer amount of energy that sucker-punched him.

The place was really loud and really colorful. The dance floor was filled with men and women from all walks of life, and the bar area was just as lively. He noticed that one of the walls was aligned with huge mirrors, lights bouncing off of them to create a pseudo-hypnotizing effect. Izuku tried his best ignore all of that as he scanned the crowds for a head of pink hair with horns. Izuku felt a knot twist in his stomach when he caught no sight of her. Was she not here? Did he come all this way just for nothing. However, before Izuku could decide to leave, a pair of hands came from behind and covered his vision.

"Guess who?" came a familiar voice.

Izuku smiled. "Ashido," he sighed in relief.

The pink-skinned girl stepped away and pouted playfully as Izuku turned to face her. "It's Mina, remember?" she reminded him. Wow, she looked...just wow. She wore a loose black tank top with the word "Pinky" written in pink font. She wore white leggings that really showed off just how attractive she was. Even her hair looked like it had been tweaked a bit.

Izuku blushed and nodded. "R-Right..."

"I'm really happy you decided to come!" Mina cheered, throwing her arms around Izuku, catching him entirely off guard. "To be honest I don't know anybody here, so it's nice to have a friend to spend time with!"

"A...A friend?" Izuku repeated, scarcely able to believe it.

"Of course!" Mina chirped as if it were the most obvious thing in the world. She then gave him a teasing smirk. "Unless...you wanna be more than just friends~"

"W-W-W-Whaaaaaa?" Izuku moaned, his whole face turning red. Mina burst out laughing and shook her head.

"I'm kidding!" she assured him, hugging his arm and leading him towards the dance floor. "Now c'mon, let's dance!"

"I've, um...never danced before..." Izuku admitted, coughing.

Mina shrugged. "That's okay, the best way to learn is to just try!"

As they approached the dance floor, they passed by a couple publicly engaging in intercourse. Izuku's eyes widened and he turned to Mina, huddling closer to her. "Mina, what the hell was that?!" he whimpered.

Mina shrugged and looked just as embarrassed. "Honestly, dude, I'm just as lost as you," she admitted. "All I know is that these parties are all the rage lately, so I just HAD to attend at least one!"

"All the rage..." Izuku repeated, lost in thought. Suddenly, realization dawned on him, and he gulped before turning to Mina once again. "Oh, God...is this one of those Sabbath parties?!"

"Heh heh..." Mina didn't meet his gaze. "Maybe?"

"M-Mina!"

"Just chill, okay?" Mina begged, the two of them finally reaching the dance floor. "Just focus on me, m'kay?" She began swaying her hips to the music, placing her hands on Izuku's shoulders. "It's just you and me here, alright? Just feel the music flow through you and do what comes naturally."

"I'll...I'll try..." Izuku muttered.

It was undeniably awkward at first, but Mina was patient with the quirkless boy, happily guiding him along until he got the hang of it. Eventually, Izuku was catching onto the the beats and rhythms, and within the next half hour he was dancing just as freely as Mina. For the first time in forever, he felt himself cutting loose and having fun. All his problems about being quirkless, getting ridiculed or ignored, they were all gone. He didn't even mind the other people he was constantly bumping shoulders with, he didn't even notice they were there. It was just him and Mina.

The pink girl was twisting her body to the music, and Izuku was hypnotized. She caught him staring several times, and giggled and winked whenever he blushed. The night couldn't be going better.

Eventually they found themselves sitting at the bar. The bartender clearly didn't give a shit about their age, he took one look at them and handed them two glasses of something blue and sweet. The two talked about several things, including their schools, their hobbies, their home life...

"Sooo...You're basically the biggest All Might fanboy out there, right?" she asked, a little tipsy.

Izuku nodded. "Yeah...and someday, I want to be a hero just like him! Someone who saves people with a smile on his face!"

Mina smiled and nodded. It certainly was a noble dream. "I, uh...hope you don't mind me asking, but..." Mina tapped her chin. "What's your quirk?"

Izuku went silent, and opted to stare at his drink.

"Me?" Mina shrugged. "My quirk allows me to secrete acid from my skin." She demonstrated by letting a little drop onto the counter top, leaving a small burn. "I can control its acidity too."

"That's amazing!" Izuku gushed, unable to hold back his thoughts about that quirk. "If you became a hero, that would give you a lot of options! Combat, rescue, support..."

"Hey, Midori-" Mina paused. "No, Izuku...you know what?"

"Um...What?"

Mina leaned in and grinned. "You're actually really cute."

Izuku's face went beet red again in an instant. "O-Oh, uh...th-th-thank you, Mina! I, uh...um..." He cleared his throat. "You're really cute too..."

Mina beamed. "Awww, really?"

"R-Really!" Izuku repeated. "I-In fact, you're beautiful!"

"Izuku..."

Izuku stopped and gulped. "Y-Yeah...?"

Mina was awfully close. "This is the part where you kiss me."

"I-It is..?"

"Mmmhmm," she hummed, puckering her lips slightly. "Now hurry it up, will ya?"

Izuku gulped and considered his options. Had he not been drinking, he would've gotten the hell out of there a long time ago...But her lips...they looked super inviting. Before he could stop himself, he was leaning in, getting ready to kiss the girl he had only met today. Their lips were only an inch apart when suddenly-

"AUUUUUUUUUUUUUUUGH!"

The two yanked themselves away and turned towards the dance floor, where the screaming was coming from. They froze, because what they saw...

"What the fuck?!" Mina shrieked, unable to believe her own eyes.

A monster. A real monster. Not some guy with an ugly mutation quirk, but an actual monster that came straight from hell. It was avian in shape, standing over twelve feet tall, its wings spread out. Feathers shot out and pinned people to the dance floor, killing them instantly. Its beak contained razor sharp teeth that it used to bite down on its helpless victims. Two grotesque, large breasts hung from its chest, swinging back and forth as it trudged around looking for prey.

Another monster appeared not soon after, covered in an array of tentacles. It grabbed the couple that had making love earlier, swinging them wildly into the air. They screamed and pleaded for help, but the monster bashed them against a wall, a sickening CRACK silencing their screams. The tentacled horror then opened its gaping maw and stuffed the two corpses inside. Monster after monster appeared, and more and more people were dying. They were being torn apart, just like it described in those articles. Blood sprayed everywhere, a small monster tearing into a poor patron not too far away. The young man's blood burst from his body, splashing onto Izuku's clothes. It smelled awful, and with the din echoing everywhere in the warehouse, it was nauseating.

Izuku was completely frozen, unable to move and inch. Mina was desperately tugging on his shoulder, shouting that they had to get out of here, but Izuku could barely hear her. One of the monsters, the bird, made eye contact with him, and he found himself drowning a horrible death in its eyes.

A harsh SLAP knocked him back to reality.

"We need to get the FUCK out of here, Izuku!" Mina screeched. "NOW!"

Izuku nodded, and the two bolted for the exits, the monsters bloodcurdling screams right behind them. Mina slammed herself against the doors, but it didn't budge. "SHIT!" she cried. "I think it's locked from the outside!" She began banging on the door. "HELP! SOMEBODY HELP US!"

"Not enough meat...just skin and bones..." was the only reply they received.

Izuku turned around, searching for anyway they could escape. He spotted a window high above their reach, but if they could somehow get up there...

"Follow me!" Izuku cried out, taking Mina's hand. The two sprinted towards the windows, Izuku explaining his plan as the remaining humans were being torn apart. "When we get there, I need you to use your acid to melt rungs for us to grip onto! We'll climb up to the window and get out of here!"

"I've never done that before!" Mina panicked, screaming as a demon rushed past her, tackling a young woman and tearing through her stomach to pull out her organs.

"You have to!" Izuku insisted.

"There's not enough time, Izuku!"

She was right, the demons would tear them apart long before they could make it.

He was scared. Scared shitless out of his mind.

But he had to keep Mina safe.

Like a hero would!

Suddenly, the bird demon took flight, swooping towards them, and it swiftly snatched Mina by her shoulders. The pink girl shrieked in fear as it carried her high up. It dropped her, but caught her again, letting out a cackle that suggested it was simply playing with its food!

"MINA!" Izuku cried out, before he felt something pulse inside him. He froze in place as he felt...something trying to get inside him. It was an odd feeling he couldn't pin down. He heard something, a voice? Time slowed to a crawl, and his vision began to turn...red...

"What's...What's happening...?" he gasped, feeling unable to breath. He collapsed to his knees, clutching his chest tightly. It hurt! It fucking HURT!

"WHAT'S GOING OOOOOON?!" he screamed as he felt something TEAR its way through his body, the pain was unbearable.

And suddenly, it was gone.

And it was replaced with a new feeling.

"I'm going..."

Some of the demons stopped what they were doing, including the one holding Mina. The pink girl was staring at Izuku with complete shock and awe, and...maybe fear?

"I'm going..."

Izuku stood up, breathing heavily. His whole vision was red, he was shaking...

And then he grinned.

"I'M GOING TO KILL ALL OF YOU!"

With a burst of speed, he rushed towards the nearest demon, his fingernails extending into grotesque claws. They cut through the demon's throat like butter, and the monster collapsed with its blood spraying everywhere. The demons stared at their fallen comrade, completely dumbstruck. Then they turned to look at Izuku, and one demon finally stepped forward.

"Damn trai-"

His head was torn clean off before he could finish. Izuku roared and charged at the demons, slashing through them like nothing. One bit his leg, he crushed its spine. Another sliced open his belly, Izuku tore him in half. The tentacled demon shot its appendages towards him, two stabbing through his flesh. Izuku grunted but caught the remaining tentacles, holding them in place.

"Let go of me, you bastard!" it bellowed.

Izuku snarled in response, and with a roar of defiance he tore the tentacles apart, the demon howling in pain. Izuku rushed in, and the demon, in a last ditch effort to take down its attacker, opened its mouth in an attempt to swallow the formerly timid boy whole. Its wide maw was a black hole lined with rows upon rows of teeth, enough to deter even the most hardened of heroes.

But not Izuku.

He caught the creature by its jaws, preventing it from devouring him. It moaned and struggled to close its mouth, but Izuku's arms remained strong. Izuku grinned maliciously, and the demon felt something stirring in its belly it never thought itself capable of feeling.

Fear.

Izuku, with all the strength he could muster, ripped the monster's jaws apart, followed by the rest of its body. Sticky, greasy, yellow blood coated his body, but he paid no heed to it as he slammed the two halves onto the ground. Panting heavily, the crazed young man looked around for more lambs to slaughter.

"Izuku!"

Izuku heard Mina crying out to him, and he saw that the bird demon was flying towards the roof, towards the skylight.

"MINA!"

Izuku felt something tear through his back, blood pouring out onto the floor, but he didn't care. With a flap of his newly granted wings, he gave chase to the bird demon, right as it broke through the skylight. The demon cackled and began to escape, calling over its shoulder, "Just try to catch me, false one!"

"I'm right here, dammit!"

Izuku came from above, slamming his foot into the demon's skull with enough force to split it open. The demon began its crash course back to the ground, taking Mina along with it.

"HEEEELP!" she cried out. Izuku, with another flap of his wings, dove down. Reaching out, he just managed to grasp Mina's hand, pulling her safely into his arms. He landed gently on the ground, carrying Mina bridal style as he waded through the pools and pools of demon blood.

"Are you okay.." he asked, almost meekly.

"Izu...ku..." Mina muttered, closing her eyes. "Thank...you..."

She had passed out, most likely due to the shock of it all. Izuku stared at her as she naturally buried herself into his chest. He felt his cheeks grow warm and he glanced away. "I...I guess I should find a place to put you down..."

It was then that he caught sight of himself in the mirrors.

The first thing he noticed was that he was now easily eight feet tall, at the very least. He noticed he wasn't wearing anything, his legs covered in black fur while his skin were shaded green. A tail curled itself around his waist, and two large, pitch black wings folded themselves against his body.

And his face...It was almost identical to all those stereotypical depictions of the devil, horns and all.

Izuku brought a hand up and ran it over his cheek. His eyes were wide and his mouth was twisted into a pained snarl. "Am I...one of them..?" he wondered out loud.

And then, without warning, everything went black.

...

When he had awoken, the sun was beginning to rise. The first thing he noticed was that he was covered in blood...Not human blood, human blood was red. This blood was a sticky, mustard yellow, and Izuku was quick to turn around and empty his stomach. A flash of pink entered his vision, and when he turned around he noticed Mina was propped against the wall, unconscious. Izuku stood up, his legs wobbling like Jell-O. He took a few cautionary steps towards Mina and knelt down to inspect her from up close.

She was safe...Thank God, she was safe.

He stood up again and began walking around the warehouse, trying to remember how he ended up here. 'What's going on?' he wondered. 'Why am I having a hard time remembering what happened?'

He tapped his chin in thought. "Mina invited me to go dancing, so I did, and-"

Something was approaching, FAST! He didn't know how, be he could sense it. Izuku rolled out of the way just in time as someone came crashing down with the clear intent to kill him.

"Perhaps you'll find peace in another life," All Might, the Symbol of Hope and Peace, grimly snarled, "ONCE I PURGE THE MONSTER WITHIN YOU!"

He lunged at Izuku, his hand preparing to strike. "Missouri...SMASH!"

Instinctively, Izuku raised his arms to defend himself, and ended up taking the full force of the blow. It hurt, like fucking hell! Izuku felt all his air and energy leave as he went skidding back until he slammed against the wall so hard it began to crack. But...he was still standing!

All Might seemed just as surprised. "I held back because you took the form of a child," he explained. "But even so...That attack should've knocked you straight off your feet!"

"T-This isn't what it looks like!" Izuku pleaded, collapsing on his hands and knees. Tears cascaded down his cheeks, he was totally afraid that he was going to die right now. "I'm not one of those monsters, I'm human!"

All Might wiped something from his mouth and grimaced. "I don't have time for your tricks, demon!" He started winding up his arm. "I promise I'll make this quick, I'll end you with full power!"

"P-Please, All Might!" Izuku sobbed, not being able to even comprehend what's going on. He pointed towards where Mina rested. "That girl, I was trying to save her, I swear!"

All Might didn't speak, and now he was right in front of Izuku. The world's greatest hero cocked his arm back, and Izuku knew that he was going to die.

The fist came crashing down.

"I want to be a hero!"

Izuku had his eyes closed, and when he opened them, he saw that All Might had stopped his punch mid blow, a few inches from the quirkless boy's face. Realizing this might be his only chance, Izuku gulped and continued. "I...I've looked up to you ever since I was a little kid, I wanted to be a hero just like you, I wanted to be able to save people with a smile...I still do..." He glanced away, more tears coming out. "But I'm quirkless, I'm nothing special. But, I still kept hanging on to my dream, because all I want to do is save people...Even if my dream is impossible, I want to keep striving towards it." He gestured at Mina. "That girl, she's a friend of mine. I saved her from those monsters, I don't know how but I did! I...I want to keep saying people, n-no matter the cost!" He stood up and stared into All Might's eyes. "B-Because...that's what you would do, All Might!"

Slowly, a smile began to appear on the symbol of peace's face, that oh so familiar smile...That smile that inspired hope in so many people. All Might took his fist, and beat it against his heart. "My apologies, citizen!" he cried out, his entire tone changing. "You have nothing to worry about anymore...Because I am here-"

Suddenly, steam began to rise from the hero's body, much to his seeming panic and Izuku's confusion. "Um...All Might?" Izuku asked hesitantly, reaching towards the number one hero. "Are you-"

The steam cleared, and in All Might's place stood...

A friggin twig.

Izuku wanted to scream, he really did, but the toll of everything had taken him, and he couldn't even muster a sound.

The scrawny guy sighed and shook his head. "I suppose you're looking for an explanation, huh?" he assumed, before smirking. His voice was somber, much more melancholy than All Might's usual boisterous speech.

"I..I.."

"What's your name, kid?"

"Oh, um..." Izuku gulped. "Izuku Midoriya..."

"Izuku Midoriya..." the man repeated, before offering something akin to a smile. "So you wanna be a hero, huh?"

...

And that's the first chapter! I know it's a lot to unwrap but it'll get easier as time goes on, trust me. I hope Izuku's Devil form didn't seem "too edgy" (even though that's probably the point...), and I know at least a few of you are gonna be so confused... But I promise, this is just a set up to basically all the other plot threads, you know? Mina, All Might, Devil form, etc...

Don't forget to review! And remember, stay wykkyd!
