I just want to let you know, this is my first time publishing something M-rated or with cursing, so bear with me, please.

And without further ado, let's get into the story.

Ch. 1: Izuku Midoriya

At a playground, a toddler with green and black unkempt hair was trembling with tears in his eyes. Behind him was another toddler, who had chestnut hair, currently crying and curled up into a ball. "Why are you being so mean, Kacchan?" the green-haired boy asked, trembling as he got into a fighting pose. "If you keep on hurting him… Uh, I'll, uh… I'll stop you myself!"

Facing him were three boys, one with ash-blonde hair, Kacchan, who seemed to be the leader; another one who was chubby; and the last one who had brown hair and a purple cap.

Kacchan simply scoffed at this as the chubby kid grew red, bat-like wings while the cap kid grew his fingers to abnormal lengths.

"You wanna pretend to be a Hero?" Kacchan asked as he slammed his fist into his palm, setting off a small explosion. "You don't stand a chance without a Quirk, Deku." Kacchan and his two lackeys then ganged up on the green-haired boy.

Later, the boy looked up at the sky while lying beaten and battered on the ground. The kid that he tried to defend earlier tried to help him out, reaching out a hand, with violet eyes full of tears. "Are you okay?"

The boy, Izuku Midoriya, simply nodded, taking the hand.

"Here's the sad truth: All men are not created equal. When I was four years old, I learned that some kids have more powers than others."

Ten Years Later

Izuku, now 14 years old and a third-year at Aldera Junior High, sat in History class as he listened to the teacher go on and on about the Meiji Period, although he admittedly would prefer it if he was discussing the Era of Quirks, the debut of All Might in particular.

All Might, the No. 1 Hero of Japan and the world's Symbol of Peace. Every time he arrived to save the day, he always had a big smile on his face and let out a big laugh that announced his presence. The smile and laughter served to show citizens he was not afraid no matter what kind of danger he was getting into and to reassure them that everything was alright with him there.

No job was too big or small for All Might as he saved people, rescued kittens from trees, and fought dangerous criminals, with a smile the entire time.

Izuku then recalled the time when All Might was in Musutafu a few months ago, where he saved two teenagers from a Sludge Villain. What he wouldn't give to see All Might in person, the man that Izuku has looked up to his entire life. He wished he could have been there when he had the chance.

Then, as the bell rang, Izuku began packing his stuff. "All Might's so amazing, no matter what kind of opposition he goes up against, he always has that big smile on his face. I wonder if someday, I can become as amazing as he is an-"

"Hey, Deku!"

Izuku winced at the voice, recognizing it as the voice of his childhood friend, Katsuki Bakugo, sporting a scary scowl on his face as he crept toward Izuku.

"You know how bad that mumbling habit of yours is? I could hear you all the way from my desk, that's how bad! You need to learn to shut your mouth before I shut it for you!"

"Sorry, Kacchan! I'm not doing it on purpose, I swear!" Izuku apologized while trying to shield himself with his arms. He always had that mumbling habit since he was young, which many people have complained about or found creepy.

"And are you seriously obsessing over All Might like that'll do you any good?!" Katsuki asked, with a hint of contempt.

Izuku could hear their classmates talking to themselves.

"What is it, like the hundredth time?"

"I know Katsuki has an awesome Quirk, but he's got such a huge ego."

"At least he only takes it out on Midoriya…"

"Heh. True that. At least I've got a Quirk."

"Honestly, I just feel sorry for Midoriya…"

Izuku's heart began to sink as he overheard everything. "W-Well, what's wrong with wanting to gather information?"

"Puh-lease." Katsuki flicked Izuku on the forehead, knocking him to the floor. "You could know everything you want, but your results from Gym class speak for themselves. With those pathetic scores, what makes you think your scrawny ass stands a chance of passing the Entrance Exam, even when compared to any of these other losers?!"

Izuku wanted to argue, but he couldn't come up with a proper rebuttal. Kacchan was right. He wasn't exactly the most athletic.

"So stop muttering or lying to yourself. It's better for you to realize this now than too late," Katsuki said before heading out with his two friends. Then, most of the other students began leaving, all except one.

"Are you okay, Midoriya?" A soft voice asked from behind.

Izuku turned to face the speaker. She was named Chacha Akaninjin, one of the few girls, or anyone else for that matter, who didn't think of him in a negative way, and the only girl at school who actually interacted with him. Because of that, she was the only girl he knew he could talk to without getting nervous. She was very cute too, having waist-length blonde hair and brown eyes along with thick long black eyelashes. Her figure was slim and petite and she had a bust size that made most of the girls jealous. Due to her Quirk, she had a rabbit-like appearance, having white fur, along with rabbit ears and tail, which often earned her comparisons with the Rabbit Hero: Mirko.

"I-I'm fine, Akaninjin. Don't worry about me," Izuku reassured while getting up from the floor.

"Okay. But listen. Don't listen to what Bakugo says," Chacha said, passing Izuku his bag. "I'm sure that if an opportunity arises, you'll be an amazing Hero like All Might, I know it."

"Thanks, Akaninjin," Izuku took hold of his bag, and the two left the classroom.

'She's right. What Kacchan says doesn't matter. I'm sure there's a chance even someone like me can be a Hero!'

As Izuku walked home through the streets of Musutafu after school, Izuku thought back to what Katsuki said in the classroom.

'So what if I'm not athletic? Some Heroes rely more on their Support Items. I mean, rather than speed or brute strength, Snipe relies more on his marksmanship! Yeah! If I just study enough, maybe I can find a way I can put my other skills to use…'

Izuku stopped and noticed his reflection in a puddle on the sidewalk. 'But will it really work though?'

His entire life, Izuku had been told that for a Quirkless kid like him, his dream to be a Hero would be impossible. Even so, he refused to believe it and did anything he could that might help him reach his dreams.

'I still refuse to believe it!'

However, if he wanted any hope of making it past U.A.'s entrance exam, he would need training. But the exam was only in six months, and what could he do in that time to prove that his dream was possible?

'First, I need to get into U.A.,' Izuku sighed for what felt like the hundredth time. 'Though Kacchan might blow a gasket when he finds out…'

"Look, it's All Might!"

That announcement broke Izuku out of his long pondering, and in haste, he ran ahead, along with several other people, as they all tried to catch a glimpse of the Symbol of Peace.

"Th-There he is!" Izuku pointed out.

In the air, there was All Might, the Symbol of Peace. He wore his classic blue and red spandex that fit well his impressive muscles. In his arms, he carried a large man with mutant features, most likely a Villain, beaten unconscious. The Number One Hero let out boisterous laughter that bellowed through the air.

Izuku's green eyes glittered; one could almost see twinkling stars around him, as his admiration for the Pro Hero was evident. "A-Awesome. All Might… in the flesh… He's so much cooler in person…"

"Careful now. You might start drooling," someone, a girl based on the voice, pointed out with a small chuckle, glancing at Izuku from the side. "You're a fan of his, aren't you?"

"Of course! All Might is amazing in every sense of the word!" Izuku declared without hesitation, still looking to the sky to watch as the Hero continued to jump from building to building, his figure slowly shrinking in the distance. "Ever since I was little, I've always wanted to be a Hero just like… just like…" Izuku's grin finally began to disappear, his shoulders and pupils falling as he spoke. Harsh reality quickly evaporated what was left of his energetic stupor.

"Is something wrong?"

Izuku turned toward the person talking to him… and immediately froze upon realizing it was a girl. She was a young woman with cyan eyes and very long, flaming red hair with a cowlick, not to mention a voluptuous figure, which included breasts that a lot of girls would kill to have. She also wore the standard U.A. uniform.

Izuku's face began to turn the same shade of red as the girl's hair. "Uh,I'mfine!Sorrygottago!BYE!" Izuku then ran off, the redhead continued to watch him with interest.

"Izuku Midoriya, Class 3-C."

Within a small club building at U.A.'s more public school grounds, there was one room that had a very gothic atmosphere. There were some couches surrounding a small table that held a chess set in the middle and a desk table sitting at the end of the room. The redhead from earlier sat at the desk, looking through Izuku's profile in a folder.

"That's right," a blond girl with blue eyes said, standing in front of her. "I got all the info I could. It probably helps I'm in a neighboring class."

"Says here he's Quirkless," she said, closing the folder and setting it down.

"There isn't anyone at the school who doesn't know. His classmates, Katsuki Bakugo in particular, bully and belittle him because of that, the only exception being Akaninjin. And Bakugo used to be his friend from what I heard."

The redhead, for a brief moment, looked angry before calming down. "Even if he's Quirkless, I can feel that there's something oddly special about him. I just can't put my finger on it."

"You mean he has a Sacred Gear?" A petite girl sitting on a couch, eating ice cream, asked. She was rather short, with white hair and hazel eyes. At the front, her hair had two long bangs going past her shoulders and several loose bangs hanging over her forehead, while the back had a short bob cut. She also wore a black cat-shaped hair clip on both sides of her hair.

"Possibly," the redhead answered, folding her arms, "For now we should keep a close eye on him. We don't want to miss our opportunity."

Then, another girl came into the room. She had purple eyes and long black hair tied into a ponytail with an orange ribbon, two hair strands that resembled antennae and drooped backward, wore a U.A. uniform like the redhead, and an athletic and shapely body with breasts even bigger than the redhead's. "Buchou, we have another notice for a Stray."

Hearing this, the redhead put the folder aside to deal with more pressing matters. "Alright. Everyone, we're moving out."

Meanwhile, Izuku's mind was still on the encounter with the red-haired U.A. student as he approached an overpass.

'I talked with a girl that's not Akaninjin! I talked with a girl that's not Akaninjin! I talked with a girl that's not Akaninjin! I talked with a girl that's not Akaninjin! I talked with a girl that's not Akaninjin!'

These eight words seemed to be the only thought in his mind as he robotically marched forward before finally calming down enough to think properly.

With a sigh, Izuku looked up into the sky with the setting sun. After seeing All Might, he lost track of time. 'Akaninjin is the only person I know who believes in me, but without a Quirk… No, I have to believe in myself. And I'll keep smiling, just like him!'

Izuku then laughed like All Might's as he made his way below the overpass. However, as he walked he didn't notice the presence of another soul.

"Finally… sustenance… Bit scrawny… but plenty…"

Izuku froze upon hearing the ominous voice. He looked around his surrounding, but he didn't see anything.

However, just when he thought that he was hearing things, he was snatched right out of the air by a claw.

The attacker had the upper body of a young woman, but she also had many inhuman features such as compound eyes on bugs such as flies, a sharp, needle-like proboscis of a mosquito's, four long segmented legs, and a scorpion tail.

"A Villain?" Helpless and trapped in the monster's grasp, Izuku could only say those two words, not only that, something about this Villain didn't seem human. Sure it might be her Quirk giving her such a monstrous appearance, but still, Izuku felt like he was staring at some monster that would fit right in a Stephen King novel rather than a human.

"Haven't eaten… long time…" The creature muttered as it stabbed Izuku's stomach with its proboscis.

Izuku felt unimaginable pain, nothing like he ever felt before as the creature began injecting him with venom, adding to the pain. 'My body… getting weak… I-I-I think I'm dying… No way, this can't be the end… Somebody, help…'

"Don't worry… be over… soon enough…" The monster raised its claw to tear Izuku apart, but before it could, in a flash of red light, the red-haired girl and her companions appeared on the scene.

The monster was startled by the new arrivals as it dropped Izuku to the side to confront the new guests.

"Don't interrupt… Unless you… would rather… eaten by me…!"

The white-haired girl was the first to charge at the creature, who tried to impale her with its long scorpion tail, but the white-haired girl managed to catch it barehanded before tugging it hard, throwing the abomination off-balance. Then, the blonde girl revealed a longsword and sliced off the stinger from the tail, causing the beast to cry out in pain.

"Well, this Stray was weaker than expected," the black-haired girl commented.

"Yeah, but at least it makes our job easier," the redhead charged up a ball of dark and red energy in her hands before firing it at the monster, obliterating it completely.

Then, the blonde glanced aside, and she blanched when she spotted the injured Izuku. "Buchou, over here!"

Everyone looked over, and they were too horrified by the sight of Izuku's body. In his stomach, was the hole made by the beast stabbing him, blood flowing out through the wound and also from his mouth.

"Oh no!" The redhead covered her mouth as she checked the boy's condition. "He won't make it at this rate. Even so, I won't let him die!" She then took out a red chess piece.

"Morning is here! Morning is here! Morning is here! Morning is-!"

Izuku groaned as he reached out from under his bed to turn off his All Might alarm clock. He groaned some more before sitting straight up in bed causing his blanket to fall off.

"Ugh, what a nightmare," Izuku groaned as he felt his head. He then looked down at his torso and lifted his undershirt seeing there was no hole in his abdomen, "But… why did it feel so real?" He got out of bed, still feeling drowsy, and he also realized he didn't remember coming home last night. "And how and when did I get home?"

However, he didn't really have much time to think it over as he had to get ready for school.

On his way to school, Izuku could feel something was different about himself, the main difference being that the sunlight seemed to drain the energy right out of him. When he got to class, he took his seat and prepared his school notebook.

"So tired…" he groaned. 'I don't know why, but it's like the sun's draining the life outta me. Is this someone's Quirk at work? Also, that dream… I still remember it so vividly…'

Then, the teacher came in, causing everyone to head to their seats.

'Maybe class will help me clear my head…'

While the classes and lectures did help him focus on other things, Izuku was still left with plenty of questions, but not enough answers. And the entire ordeal with the sunlight sapping him of strength did not do him any favors as he sat by himself under the shade of a tree as he dug in to the lunch prepared by his mom.

"I'm starting to think that wasn't a dream," Izuku stated, then he realized something else. "But then what happened?! I remember that Villain stabbing me, and while I'm not one to judge people by appearances, even with the most bizarre Mutant Quirks, something about her didn't really seem human… As a matter of fact, how am I still alive right now? And I think I saw a red light and heard some voices before I lost consciousness…" He mumbled on and on about his situation.

Later, after school was over, Izuku walked back home, still feeling lethargic under the sun. "The sun's still making me feel weird. Should I consider going to a hospital?" Izuku asked himself.

The sky was already dark with the sun setting on the horizon by the time Izuku made it back to his neighborhood. However, now in the darkness, his body seemed to have the opposite reaction as not only did he feel his strength coming back, his senses also seemed sharper than ever. He could see clearly in the dark, better than in daytime even. In addition, even from a block away, he could accurately hear people's conversations. "It's like the reverse of what's been happening to me today. Light makes me weak, but darkness rejuvenates me. What's happening?"

Before Izuku could go off on another mumble storm, he felt a chill up his spine. "Is someone there?"

Izuku cautiously turned around, and in the direction of the setting sun, he noticed a shapely figure approaching him. It was a woman, apparently a young adult. She was dressed in some sort of leather dominatrix suit, consisting of nothing more than a black bra and panties. She had broad shoulder pads with three spikes and black gloves covering her arms, matching with black boots which went up her knees and black straps around her thighs. She was a very attractive woman with flawless pink skin, large breasts, long and smooth black hair that went past her firm butt, and pinkish eyes.

"Well, lookie here. I take my eyes off you for one day, and during that time you just had to go get yourself reincarnated as a Devil," she said.

'Who is this lady?!' With his guts warning him of danger, Izuku slowly took a step back, or at least, that's what he intended. Instead, he ended up making a leap. 'I meant to back up a little, not jump!'

"Looking for a way out?" the woman asked. "Tell me, who is your master?"

Izuku turned around and ran as fast as he could, not daring to look back. As he ran, he suddenly noticed black feathers falling from the sky and looked up to see the woman flying, supported by a pair of black bird-like wings. 'She has wings?! Are they from her Quirk? She looks like a demon with those wings!'

Then, the woman came down to the ground, right in front of Izuku.

"So let's see, it appears as though your friends and master are nowhere to be found. You show no signs of disappearing, nor any magic circles being deployed. Therefore I will assume you are nothing but a Stray, is that correct?"

Then, red light flashed from her hand, forming into a spear. "How convenient, since I was planning on killing you anyway. Just makes things a whole lot easier!"

Izuku, realizing what was going to happen, tried to run-

*SHINK!*

Only to collapse to the ground, with a light spear impaling his torso. "It burns… this is the worst pain I've ever felt!" Izuku gagged in pain. When he touched the spear, his hand felt like it was on fire.

"Hurts, doesn't it? Light is a deadly poison to your kind, it burns you from within," the woman taunted. "I thought I finished you off, but it seems you're quite the tough one." The spear of light was then yanked out of Izuku's body and back into the woman's hand. "Don't worry. I'll put you out of your misery shortly."

'I'm done for! Someone, help me please!'

Then, a wave of dark energy was fired at the spear, destroying it.

"What did you just do, you little shit?!" The woman questioned. Then she noticed a red light. "And what the hell is that?"

On a red glowing circle, there stood the red-haired U.A. student whom Izuku recognized.

"Keep your hands off of him," the girl warned.

"That hair… You're from the House of Gremory!" the woman said.

"My name's Rias Gremory," the girl introduces herself. "And who are you, other than a Fallen Angel?"

"Rias… Gremory…? Did she come to save me?" Izuku groaned, looking behind him.

"So then he's a part of your household, I take it?" the woman asked.

"If you bring any harm to him, you'll get no mercy from me," Rias warned.

"Sure, fine. My bad," the woman apologized as she unfurled her wings. "But it's unwise to let your servants run loose like this. Next time he's out for a stroll, he might run into someone who'd prefer to hunt him down."

"I appreciate the friendly advice. Bear in mind, if anything like this happens again, I'll make you regret the day you crossed paths with the House of Gremory, my friend," Rias said as she smiled like a fox.

"No offense to your noble household, but you should bear in mind that the same thing can be said to you," the woman then flew off into the night sky. "My name is Raynare. Remember it."

After getting some distance away, Raynare scowled in frustration.

'Damnit! Not only did I fail to keep an eye on that brat, but now he's been recruited by those filthy Devils! If word gets out of this… No, wait! There's still a way I can redeem myself!'

Back with Izuku, he could barely register the events happening around him thanks to the burning hole in his stomach. The woman was apparently a Fallen Angel and somehow, this Rias person managed to drive her off. What was happening? He couldn't think anymore as he fell on his face and darkness enveloped his vision.

"Morning is here! Morning is here!"

Izuku was aroused from his rest once again by his All Might alarm clock. As his eyes adjusted to the morning sun, he sat up and turned the alarm off.

Snorting in irritation, he rubbed his eyes as his sight adjusted to the morning sun. He slowly sat up and slammed his alarm shut. "Huh? I'm still alive?" Izuku muttered to himself groggily. "I thought that woman with the black wings was trying to kill me, then that red-haired girl saved my life." He gave out a tired yawn. "I guess it really was just a bad dream…"

Izuku flipped the sheets off his body, only to look down to realize something very, very wrong. "Hold on, what happened to all my clothes? Why am I naked?!"

Then he noticed something else. There was something else in bed with him, covered by the sheets. Izuku cautiously grabbed the covers and pulled them up. Underneath the blanket, was Rias Gremory, sleeping peacefully in the nude.

And there's the first chapter. So I tried making it more unique by having a Stray Devil be the one to fatally attack Izuku, instead of Raynare. I thought about having the Sludge Villain be the Stray that would attack him, but then I figured I wanted to use him later in the story (also with him finally returning in canon and all).

Another thing, something you might've missed, I'm genderbending Yuuto Kiba, so it's Yumi Kiba instead. Right now, the only mention of it is a "blonde girl with blue eyes." I don't want anyone getting confused, so I figured I should say it.

See you next time. Go beyond! Plus Ultra!
