Hello my Hero Academia people! I have another fanfic I write called "His Reasons" and that will still be my priority but since I'm off for the rest of the month I thought I'd try something new as well. Warning, this is different then my other fanfic and things get a little more spicy, not too spicy but you'll see. Hope you enjoy and let me now if I should continue cause I'm not sure.

The first day Bakugo met her started out like any other.

He was forced by his mother to go to the store for some groceries on his day off even though the boy insisted that they still had plenty in the cabinets. But just like everything, his mother didn't listen in the slightest.

Stomping into the store, Katsuki groaned, not understanding why he had to do such a stupid thing. He had far enough on his plate as it was, seeing that his entrance exam for U.A. was coming up next week.

The boy shoved a couple items into the basket before aggressively crossing them off on his list as fast as possible. The sooner he got this done the sooner he could go 's all he cared about right now.

Moving to another aisle, the boy stopped when he found a display of his favorite spicy noodles a couple feet away from him. There seemed to be some kind of sale happening so the majority of the shelfs were barren and empty, with only one bowl on the center shelf. Perfect.

Bakugo stomped up to the display before licking his lips, already feeling the warm heat that the noodles would bring and reached forward, fully intending on grabbing the last pack.

Although as his hand touched the plastic coating, his fingers bumped into another who was reaching out as well. Frowning at the action, Katsuki looked up to find a girl staring back at him.

She was wearing a black oversized jacket with the hood covering her eyes, although Bakugo could just barely make out her long light purple hair hanging out of the sides in a half ponytail. It was like she was trying to hide her appearance, although Bakugo didn't really care about that now. This girl, she had a lot of nerve.

He expected her to pull back and apologize like most girls used to do at his middle school. It didn't help that Katsuki always wore an unpleasant expression which scared most of them away. It's not like he minded though, Katsuki had more important things to worry about then frivolous girls.

Although strangely enough, her reaction was not that at all, watching the girl instead grip tighter to the bowl and try to shake his hand off. Was this girl itching for a fight? "Hey! Hands off extra! I saw it first so get lost!"

He slapped her hand away only for her to clamp down on his arm before smirking under the hood. "Who are you to tell me what to do? I think it's you that should get lost."

Narrowing his brow in annoyance, Bakugo pulled back then, reaching for the noodles as the stranger blocked his advance. "What did you just say to me?! You wanna fight?!"

She only shrugged her shoulders though. "Bring it on angry porcupine boy."

Gasping at the insulting nickname, Katsuki felt his palms grow in heat as he threw an explosion in the middle of the store, causing the display behind them to explode. "Do you think I'm playing around? Just give me the goddamn noodles before I set you on fire!"

Although she only seemed amused. "Ooh touchy. Go ahead and try, if you can catch me."

Then before he could register it, the girl quickly grabbed the last bowl of noodles before running off through the store, causing Bakugo to shout. "What the...Get back here you little..!"

He set off then, chasing the girl through the aisles and throwing explosions in her direction as the other shoppers begged him to stop. Although Bakugo couldn't stop, he needed to show her who he was messing with. "Stay still so I can kill you!"

The girl stopped before jumping onto one of the displays and smirking. "Now what fun is that? You better step up your game porcupine boy. I'm not really impressed."

Growling in response, Bakugo put his hands out before letting off a giant explosion and blowing up the entire display she was standing on. "How's that for impressive?"

Although he couldn't help but be surprised as the girl jumped off the table before completing a backflip over his hand and landing gracefully with a light tap. "Nah, I've seen better. Ah well, see you. Thanks for the fun."

Not fully understanding, Katsuki raced forward only to be pulled back by one of the store owners, obviously very upset that the boy had destroyed everything. "Hey, you! Come with me! You better be willing to pay for this, you hooligan!"

Pulling against the man, the boy grumbled only to hear another employee grab the girl that was trying to escape. "And where do you think you're going?"

Bakugo smirked at that, knowing that girl would be in just as much trouble when he watched her lean toward the workers ear before whispering something out as his eyes grew dull for a moment.

Then a second later, the man loosened his grip and bowed as she headed towards the exit. "I'm very sorry about that. Have a nice day."

Katsuki's brow turned to confusion as the girl then waved him off before turning to meet his eyes, a knowing smirk now on her face. Wait, they were letting her go?! What the hell, she was responsible for all this!

Then to dig the knife in a little deeper, the girl pulled out the last bowl of noodles from her pocket before showing the boy and waving it around as if to heckle him. That bitch, she was messing with him!

Turning on her heels, she then walked out of the store causing Bakugo to go after her, only to be stopped by the employees. "Wait, let me go! She's the one that started all this bullshit! Don't let her go assholes!"

Although the workers didn't seem to listen, instead pulling the boy into their office so that they could call his mother.

All throughout the process, Katsuki had one thought in his mind. Who even was that girl, and how did she get out of this so quickly?

Katsuki one thing for certain though, she was going to pay for messing with him.

A couple hours and one long phone call later, Bakugo walked out of the store even more angry than ever. His mother was beyond pissed at him for destroying that store but every time he tried to mention that girl, the store workers didn't believe him for some reason. It was like she was never there in the first place.

Shoving his hands in his pockets, he made his way down a side street only for a soft chuckle to echo above him. "Took you long enough. What were you even doing in there?"

Widening his eyes at her voice, Bakugo looked up only to find that very same girl sitting above him on the fire escape ladder to one of the apartments, eating his noodles. "You..get your ass down here so I can kill you! How in the hell did you even get away, you brat?!"

She thought for a couple seconds before shrugging her shoulders and jumping down from the stairs. "Now that's a secret. Okay, I'm here now, so what are you going to do to me Mr. Scary porcupine man?"

At the sound of his nickname, Bakugo frowned before grabbing the girl by the collar and pushing her closer to him. He needed to show her who she was messing with. "How dare you try to make an ass out of me back there! Do you have a death wish?!"

Although the girl could only laugh though, obviously not intimidated in the slightest. "I hate to break it to you but I think you did that all on your own."

Her words only made his grip tighten though, already over her behavior. "Why you..!"

Suddenly a gust of wind tore through the space, causing the girl's hood to fly backwards as Bakugo locked eyes with her for the very first time, his own gaze growing large at the realization.

Her eyes looked so unique, so different from anything he had ever seen before. They seemed ominous yet somehow hypnotizing at the same time. They were light purple in color to match her hair although her pupils didn't look human. They were small thin black lines that only filled a quarter of her eyes, kind of like a snake or a lizard. Just staring at them brought a sharp shiver of uncertainty down his spine. It was like they stopped him into utter silence, drawing the boy into a trance. He had never seen anyone like her before.

Looking down at the floor, the girl spoke back, this time slower. It seemed she understood the power her eyes had. "You know it's rude to stare."

Blinking back in surprise, Katsuki felt his hands loosen of her collar before falling to his sides as she spoke again, desperate to change the subject now. "Say, are you always this touchy? Oh wait, I know who you are. You're that kid that got kidnapped by that sludge villain the other day, right? Talk about embarrassing.."

At her words, the boy's chest lit up again, his time in anger, snapping him out of his past delusions about her eyes. "Shut up! Who even are you anyways?"

Thinking about his question for a moment, the girl only smirked. "Oh come on, you're gonna have to do a whole lot more than that to get my name. How about we start with yours first?"

Katsuki noticed the deflection of the question and huffed. "No way in hell am I giving some random extra my name."

This caused the girl to frown though. "Alright then, I guess I'll just have to keep calling you angry porcupine boy then. Hey by the way angry porcupine boy, have you ever thought of anger management classes? I think they'd be good for you."

Bakugo balled his fists in annoyance then, shouting back. "Would you stop with that!"

Although she only kept going, knowing that the name was bugging him. "I'm sorry, you won't give me your name so angry porcupine boy it will have to be until then. I know it's a bit long but what can you do, right? Also I really was serious about those anger management classes. You know if you want, I know a guy that..."

Bakugo cut her off then, already reaching his boiling point as he shouted in her face without thinking. "Fine goddamn it. My name Bakugo Katsuki, aka the new future number one hero. You got that?!"

He then realized that he had just played into her hand, swearing back as the girl saddened for some reason. Katsuki thought she'd be happy to learn his name, so why did she look damn depressed all of a sudden?

Speaking back in utter boredom, the girl then turned from him "Oh, so you're one of those. How generic. I thought you were way more interesting than that."

Narrowing his eyes in confusion, Bakugo stepped forth. "What the hell, do you have something against heros or something?"

This caused the girl to stare down at her feet, thinking for a moment before bitterly laughing back. "Yeah, or something. Why on earth do you even wanna be something like that anyways? It's so boring."

Her words choice was strange, it was like she had some kind of hang up on heros for some reason. Too bad Bakugo wasn't going to be just any hero.

Puffing his chest out, Katsuki replied. "And what the hell is wrong with that? I'm not just going to be a hero, I'm going to be the best!"

Although she still didn't seem impressed, just waving him off and yawning. "Yeah yeah, like I haven't heard that one before. Well good luck with that. Lemme know how that works out for you."

His eye began to twitch then, held up on her words. "Hold on, are you saying I can't do it?! Screw you asshole, you watch. I'm going to be the best, even better than All Might!"

She stood there silent for a couple minutes before curling her lips into a small smile, laughing back, enjoying the declaration. "I take it back, turns out you are interesting Bakugo."

Taking a step closer then, Katsuki narrowed his eyes in confusion as she reached a hand up to touch his face. Did she want to fight again? "W-What the hell are you doing?"

Just then, his eyes locked onto hers and that uncomfortable hypnotizing feeling washed over him again, causing the boy to be unable to move as she shushed him.

Tracing her fingers across his face lightly, Bakugo shivered as she hummed back. "It's a shame you want to be a hero Bakugo, you could do so much more. Ah well, I guess it will still be fun to watch you struggle."

Not really understanding, the girl then placed her slender fingers to his lips before smiling. "This was fun, so let me give you a parting gift."

Then before he could register it, the girl leaned forward, pressing her lips against Katsuki's roughly as the boy gasped in surprise. What the hell was happening and why couldn't he pull away? No, it was like he didn't want to pull away.

Grabbing onto the sides of his face, she pushed deeper into him causing the boy to groan, her body brushing against his and causing a sharp shiver to course through him all at once, now somehow hungry for her touch and confused at the same time.

He gasped again when Katsuki felt her tongue brush the top of his mouth, a soft gasp of surprise echoing through him as his whole body began to shake with anticipation. His breath grew shallow as he reacted to her kiss, her tongue reaching a bit further and causing the boy to let out an unexpected moan. Suddenly it was like his body was begging for her, following her whims and desires with no resistance.

She pulled away then, Bakugo still completely in a daze as she licked her lips and winked seductively. "By the way, my name is Sienna. Maybe I'll see you around Katsuki."

Then, just as quickly as she arrived, that mysterious girl was gone, leaving Bakugo by himself, not really knowing how to process what had just happened.

Placing two fingers up to his lips, he could still feel the warm heat from her, Katsuki's nerves waking up all at once as he let out a loud and confusing scream. "...WHAT THE FUCK!"

The boy then paced back and forth as he ran his fingers through his hair in confusion. He was just kissed, that crazy ass girl just kissed him! What the hell even was that?! Who just kisses someone randomly without knowing anything about them?! That was his first kiss too..

Although he still couldn't stop himself from placing his fingers back to his lips, remembering the sensation and the feeling he had pressed against her. She said her name was Sienna? Who even was that girl? Katsuki knew he would be lying to himself if he said he didn't want to see her again though.

Shaking his head, Bakugo's confusion quickly turned to frustration, now balling his fists into the air and shouting. "I'm going to fucking kill you when I find you!"

The U.A. entrance exam came and went rather quickly although the only thing Bakugo could think of during the entire time was that crazy girl that kissed him. He wondered what the hell she was even thinking. It had been a week since then and every time someone that remotely passed by him, the boy couldn't help to turn, expecting it to be her.

Although he had no luck in his search and everyone around him didn't have the faintest idea the girl existed. It was like she wasn't real.

Sighing to himself, Katsuki roughly greeted his mom before slumping up the stairs to his room and slam open the door, fully ready for some damn peace and quiet.

Although that's not what he got.

Sitting at his desk was the very girl herself, swirling around on his black spinning chair like there was nothing wrong with the fact she was in his house. "Oh, there you are. Took long enough."

Widened his eyes in confusion, Bakugo slammed his door shut before shouting towards her. "What the hell are you doing?!"

Shrugging her shoulders, Sienna replied calmly. "Waiting for you."

Although the girl was missing the point. "I mean, what the hell are you doing in my house?! How the fuck did you even get in here?!"

Sienna thought for a moment before pointing to his open window, causing the boy to gasp. "You broke into my house by climbing through the window?! What is wrong with you?!"

Standing up from her spot on the chair, the girl shrugged again. "It's your fault you left it unlocked. You know, you should really do something about that. I mean, who knows what kind of crazy people could break in…."

Totally obvious to her own irony, Bakugo hissed. "You mean like you?!"

Sienna only frowned then. "Okay, now that's just rude. Do you know how long I waited for you?"

Although Katsuki wasn't amused, already grabbing the girl by the arm and pushing her back towards the window. "I don't care, get out of my house you damn woman!"

Moving her back a couple feet, Sienna pushed back only for the two to trip on their own feet and tumbling onto the bed roughly.

Grumbling, Katsuki propped himself up only to find them in a suggested position, now practically sitting on the poor girl. She didn't seem to mind though. "Oh how forward Katsuki. You know, if you wanted to do this all you had to do was ask."

The heat started to rise in his cheeks when suddenly, Katsuki's mother called up from downstairs loudly. "What the hell are you even doing up there Katsuki?! Quiet down would you!"

Sienna opened her mouth to speak when Bakugo gasped, clamping his hand down on her mouth before echoing back. "Shut up you old hag!"

They remained silent for a minute until his mother's voice was no more and Bakugo sighed. Who knows what kind of reaction she would have to seeing a woman in his bed like this? She'd totally misunderstand.

Now turning his gaze back at Sienna, Bakugo leaned closer. "Now tell me, why the hell are you in my house, and don't give me that kind of bullshit like before!"

She muffled underneath his hand causing Katsuki to let go, Sienna now staring up at him. "You had your entrance exam today, right? I wanted to see how it went."

Katsuki's eyes widened then, not expecting that response. "Why do you even care about that? We don't even know each other, you extra."

He sat up, allowing the girl to do the same as she brushed off her black dress. "I already told you Katsuki, you're interesting, that's why. You're not like any wannabe hero I've met before."

Narrowing his eyes in confusion, Bakugo replied. "Is that some kind of insult?"

Although Sienna just shook her head before smiling. "Not at all. In fact, very few people have caught my interest like you have. So you should feel special."

Yet Katsuki didn't feel special. "I should feel special that you broke into my house and attacked me? If that's the case, I don't wanna be goddamn special. I want you to leave me alone!"

Sienna frowned at that before crossing her arms over her chest. "Attack you? What are you talking about Katsuki? I thought we had a nice conversation before…"

This caused Bakugo's face to rise in heart, recalling the kiss. "You call punching my face with your face a nice conversation? Bullshit, that's harassment you crazy woman!"

Thinking about his words for a minute, Sienna then gave a sly smile, wrapping her arms around his shoulders. "What, do you want me to do it again? All you have to do is ask.."

He saw her lean forward only for Katsuki to panic, not knowing what he wanted. Then he pushed her backwards, his reply not sounding fully convincing. "No...Hell no! Get the hell away from me! This is what I'm talking about! Why did you even do that in the first place?!"

Falling into the mattress at the rejection, Sienna answered calmly. "Why did I kiss you? Simple, cause it was fun."

Although Bakugo couldn't accept that. "So you just go around kissing people for fun?! What the fuck is wrong with you?"

She thought about that for a minute before shaking her head. "You're wrong Katsuki. You're the first person I kissed like that. I just wanted to show you how entertained I was when we spoke. I wouldn't do that to just anyone, only those that interest me."

Her words were strange and broken. That wasn't how normal people were supposed to react. Well then again, breaking into someone's house wasn't how anyone was supposed to react. There was something strange about this girl.

Looking at her nails, Sienna spoke again. "So are you going to tell me how the entrance exam went or am I just going to have to assume?"

He knew he probably should've kicked her out of his house but somehow, Katsuki didn't want to, just sighing back and giving up. "What do you think happened? I dominated the competition of course. It's only a matter of time before I get my acceptance letter."

Sienna listened to his words before frowning. "Oh, that's nice. I was kind of hoping you'd fail and not go to that godforsaken school but also on the other hand, U.A. would be blind not to have you in the hero course, so I guess that's good. Congratulations."

It was almost like she was disappointed that he passed which was odd. It was obvious she had something against heros. "There is no way I'd fail. I already said it before, I'm going to be the number one hero and that's final! I won't let anyone else surpass me."

Blinking in surprise, the girl's expression then turned from sadness to amusement, now letting out a small laugh. "Of course you'd say that."

Then, he lifted her arms up in a long stretch before yawning. "Alright well. Now that I know I guess I should leave. Thanks for the chat Katsuki. Sorry I bothered you. I won't come back since that's what you want."

Standing from the bed, Sienna started to move towards the window when Bakugo realized that this may be the last time he saw her, and he still didn't know who this woman was.

Then, he did something expected, he grabbed her arm, causing the girl to freeze. "Sienna, hold on damn it…"

Blinking once, the girl turned around towards him in question. "Yeah?"

Not really knowing what to say or do, Katsuki spoke back. "Listen nerd, you can't just break into my house and leave when you feel like it! Who the hell even are you and how come no one knows who you are?"

Looking down at his arm, Katsuki swore he saw her eyes sadden a bit. "You don't need to know about that. I'm no one. I'm just curious about you, that's all. You can forget I was even here."

Although that's not what Bakugo wanted, desperate to know more about the mysterious girl. "Don't tell me what to do! I'll remember who I want to, damn it!"

Sienna's eyes widened at that, feeling her chest lighten just slightly as she reached forward. "Oh no, look what you did..."

Remaining silent, the girl placed two fingers on his cheek as her eyes locked onto his, that familiar hypnotizing sensation returning all at once. "Shit, I really want to kiss you right now..."

Then, she leaned in closer and instead of pulling away like he probably should have, Katsuki remained still as her body pushed into him, her lips now laying claim once again.

Grabbing onto his shirt, Sienna ran her lips across his own as the boy groaned back, welcoming back that familiar sensation like a couple days ago. He really shouldn't be doing this but it was like he couldn't say no to her movements.

She bit down on his bottom lip before using her hands to shove him down onto the mattress below them and continuing her claim on his lips, the girl groaning as well from her own pleasure.

Running her hands up his chest, he felt her tongue brush the inside of his mouth as he let out a quick moan and Sienna smiled through the kiss, happy with the result, now playing with his spiky hair and running her smooth fingers across the top.

She then ran her mouth across his bottom lip, slowly pulling it up as Katsuki groaned underneath her. "Sienna..fuck.."

The sound of her name brought a shiver to her own spine, casting her eyes towards the boy playfully. "God, I love my name coming from your lips. Why do you drive me so crazy Katsuki? I wish I knew.."

Feeling the hot breath in her ear, Katsuki shuttered at the sensation when suddenly, her phone began to ring in her back pocket, shaking the girl out her delusion and pulling away sharply. "What the hell.."

She then looked at the surface before frowning as Bakugo spoke in short breaths. "What is it?"

Choosing to stay silent for a moment, he saw Sienna sigh heavily before throwing her phone onto the bed and changing her attitude into something more calm. "I'm sorry, looks like I got carried away. Seems like I'm going to have to end this now. What a pity.."

Bakugo turned his eyes in confusion as the girl then leaned back towards himself pressing her lips together. "Don't worry, after this you won't remember a thing.."

The boy tried to stand up then, only for Sienna to push him back down before letting her voice return in the form of a beautiful melody. Her song traveled across him as he processed the words, now feeling numb in his entire body.

Listen to my song and sink

Deeper into the ocean deep

Have your memories wiped away

But still to live another day

A girl with no face and no song

A girl that will never belong

Little hero, don't you see

You have been bewitched by me

So don't you yell and don't you shriek

For now you will go to sleep

With every word, Katsuki's mind dragged further and further into her lyrics, his body complying to her wishes all at once and forgetting about the girl that had befallen his life so suddenly.

Once he was unconscious, Sienna sighed before looking down at her phone. What was wrong with her? She shouldn't be so caught up in a hero. That would just be really bad for her later.

That boy Katsuki was only a plaything, a means to fool around. She needed to stop thinking so much about him and get head on straight.

Sienna already had far too much to do as it was.

Walking into the old abandoned bar, Sienna threw herself onto one of her barstools before slamming her fists onto the counter. "One on the rocks."

Kurogiri looked at her in confusion before sighing. 'Aren't you underage? You shouldn't be drinking.."

Although the girl only frowned as she hissed back. "I had a bad day, alright? So give me the damn alcohol Kurogiri. What are you, my mother?"

He was just about to reject her again when another voice stopped him. "Give it to her, we want her to join us, don't we? We should be welcoming hosts."

Kurogiri sighed in defeat and started to get to work as Shigaraki came up behind her. "What took you so long? I thought you were only going to surveillance the school?"

Sienna rolled her eyes in response. "Shut up, I did what you asked, I just got a little distracted that's all."

This caused the villain to smirk. "Oh, and what boy toy did you pick up this time? I hope you played around with him well."

Sienna smiled at that, nodding her head in approval and thinking what that wannabe hero. "Of course, who do you think I am? How else would I spend my time?"

Shigaraki seemed satisfied with that, now pulling out a large map and showing the girl. "Speaking of which, now that you finished checking the area, we can finalize our plan to kill All Might. I assume you're still in?"

Staring down at the plans, Sienna couldn't help but smile. "Of course, why the hell do you think I'm here anyways?"

As his eyes grew darker, Shigaraki replied. "Oh I remember exactly why you're here. You are a villain after all. My little Sienna, or should I say, Enchantress?"

Hello and welcome to the chaotic couple that is Sienna and Bakugo. So first off, she's a villain. That's a big oop. Also as you realized this is going for a different tone then my other fanfic. I just wrote this for fun during the whole "out of work" thing for the rest of the month.

Maybe I'll continue it but I'm not sure.. Lemme know what you think.

I really enjoy the quailing conversation between the two for some reason. It's really fun to write.

Next Chapter: (If there is one heh) Bakugo meets Sienna during the USJ attack and he's got some questions for her.
