Explosions CAN be Contained!

Hey guys, this is my second fanfic on here and I am sooooo excited to share it with you guys! I just recently got super into this show and have completely fallen in love with all of the characters, particularly Bakugo since he is such a wild card. The anime doesn't give him much background or a deep personality besides ANGER! So I thought it would be fun to write him as close to how he would normally talk and act as possible so that when he shows off his soft side, it's reallllly cute! Originally I wrote this pairing Bakugo with an OC who would challenge him and really put him in his place, making her a good candidate as someone Bakugo could fall for. But then I figured it would be more fun for you guys to be in the story and play the role of a character I've thought long and hard about, especially the quirk (Sorry in advance to those of you who may not identify with the role bc I wrote the fic in the perspective of a girl and realized it a little too late). There's also tons of Ochaco and Izuku action which I think is such an adorable pairing. I hope you guys like it!

CHAPTER 1

Class 1-A stood in an empty training ground waiting for something to happen. Their teacher, Mr. Aizawa had mentioned that a new student would be re-taking the entrance exam due to their lateness in entering the course. However, this entrance exam would be different from the typical one. A week ago, students from the class voted for the candidate most challenging for the new student to compete against in a battle, challenging and showcasing what kind of training they would need to catch up on for the remainder of the school year. Naturally, everyone voted for Katsuki Bakugo due to how exhausted they were from their last assignment. Bakugo didn't think twice when he was selected, reminding his classmates of how much better he was than them and how he was excited to put the new student in their place.

Bakugo now stood in the middle of a dirt clearing where Mr. Aizawa explained the fight would commence. It had been almost an hour with no sign of any new student showing up.

"Come on! What's taking so damn long?!" Bakugo exclaimed, kicking the dirt. "I thought I'd get to kick someone's ass, not wait for it to show up!"

Suddenly, you shouted something from the distance, running toward the confused group of students. Izuku Midoriya noticed first, and called out to you, "Hey! Over here!"

"Shut up you damn nerd, it's not like they can hear you all the way over—" Bakugo's snide remark was cut short when you, out of breath, held onto his shoulder for support.

"Sorry, I'm pretty sure my house had a blackout or something because my alarm did not go off when I wanted it to…" You didn't look very flashy. You wore a (f/c) unitard and matching mask as your costume and your long (h/c) hair was done up in a French braid. Everyone was curious nonetheless, especially the other girls who were largely outnumbered by the boys in their class. Bakugo grunted in annoyance and shrugged out of your grip, causing you to stumble forward.

"It's alright, it happens to the best of us." Aizawa said in his typical monotone voice. You nodded and looked up at Bakugo who was at least a foot taller than you.

"Is this the guy I'm fighting?" You asked, pointing to an annoyed Bakugo.

"Yes, this is Katsuki Bakugo. Do you want to introduce yourself or…" Aizawa watched as you slowly backed away from Bakugo, eyeing him up and down.

"Hmm… I'll introduce myself after I win." You said casually. Your words made everyone's jaw drop. No one had ever seen such confidence, especially in front of the most ruthless student in the class.

"What did you just say?!" Bakugo asked, seething with rage.

"Oh, I just said that I'll tell you my name after I win this battle." You said in a bored tone, looking down at the ground.

"Win? I think someone needs to be put in their place!" Bakugo growled, arms outstretched and ready to blow his opponent to smithereens.

"Now before you fight, just a reminder that, like the Sports Festival, you can only win by making your opponent either go out of bounds or knock them out." Aizawa stated, placing an arm on Bakugo to calm him down.

"How about I just knock her out right now?" Bakugo asked, making little explosions in his hand.

"Alright." You answered casually, and just like that you sprinted forward, faster than Bakugo anticipated, leaving him no time to react as the your fingernails became long and sharp, scratching his exposed arm and leaving a small cut. In the time it took for you to cut, you caught a single drop of blood on your steel-like nails and licked them clean, smirking. Bakugo fired an explosion but you dodged it quickly, backing away.

"What did you—" Bakugo stopped talking as you lifted your hand up to wave. His eyes grew wide with shock as he realized that he was waving too! You then jumped up and down, causing Bakugo… to jump up and down! It was like his entire body was under your control. He couldn't speak, it was like his lips were sealed shut.

"My name is (Y/N)," both you and Bakugo said in unison, "and believe I have just won this fight." Class 1-A watched in awe you punched herself in the face, making Bakugo punch himself and fall to the ground. Izuku was especially curious about your quirk, noticing that each blow you took to yourself only seemed to effect Bakugo. You saw that Bakugo's nose was bleeding like crazy, so you walked him over to the white line. Suddenly, as if you broke the spell, Bakugo was able to move at his own free will again, rubbing his nose and seeing the blood. Before he could yell you kicked him hard in the stomach, sending him stumbling over the line indicating that he was out of bounds. The class cheered wildly and ran up to you, beaming with pride.

"Congratulations, you have passed the re-take." Mr. Aizawa stated in his usual monotone voice, writing something down on a clipboard. "You can go to the dorms and unpack or what have you. As for the rest of you, seeing as you all just had an exhausting retreat yesterday and our new student needs to get settled, I think it's safe to say that you all have the rest of the day off."

"Thank you!" Izuku said, seeing as he was the only one who heard anything Aizawa said. He quickly joined the rest of his classmates who were all surrounding you.

"It's so great that there's going to be another girl! I've been getting so sick of dealing with these crazy boys, I thought I might die!" Ochaco Uraraka exclaimed, jumping up and down.

"Yeah, your quirk is so powerful! The only other person who's ever defeated Bakugo was Midoriya and it was a crazy battle." Momo Yaoyorozu added, pointing to the awkward green-haired kid standing behind the large crowd.

"Wha… me?" He asked, suddenly being pulled toward the girls as Momo grabbed onto his shirt.

"Tell her about your fight with Bakugo!" Toru Hagakure yelled, shaking his shoulders.

"Alright… It was super hard and I had to use my quirk on him which I didn't want to do in the first place, but yeah… Anyways, can you explain to me what your quirk is? I was trying to figure it out as I watched you fight, but from what I understand I think you need a person's blood to control them, and after that you can hurt them or make them do anything you do, but it doesn't seem to affect you… why is that? And how did you stop controlling Bakugo at the end of the fight?"

"Well, when I drink another person's blood it takes a while for it to leave my system, so hypothetically, I could still control Bakugo until tonight, but I can decide when I want to control someone easily, it's like an on and off switch for me. My nails, if you noticed at the beginning of the fight, grew extra long because of how much iron I can store up in my body, it allows me to make nails strong enough to cut through clothing if I wanted to."

"That's so cool! What's your hero name? Have you picked one out yet?" Ochaco asked.

"No, not yet. I'll probably just use my regular name to—"

"HEY! WHAT THE FUCK WAS THAT?!" An angry voice called from behind the crowd. Izuku stepped forward to see where the voice was coming from.

"Oh, hey Bakugo… nice fight out there, huh?" Izuku nervously greeted, trying to stop him as Bakugo angrily walked towards you. He was holding a white, blood-soaked rag up to his nose.

"That was a dirty trick you asshole! You can't expect me to walk away from a fight that didn't happen!"

"It did happen. You shot your weird fire quirk at me, I dodged it, and then the fight ended because I won. You can't call my quirk a dirty trick just because you weren't ready for me." You stated, looking up at the seething blonde.

"You- I want a re-match! Your quirk is—"

"Awesome?" You cut in, smirking. This caused the other girls to laugh as Bakugo became flustered.

"FUCK THIS!" Bakugo was so angry he didn't know what to do, so he let off a giant explosion in the air and was about to punch Izuku before Kirishima stepped in and moved him away from the laughing crowd.

"Wow, he really has a bad temper." You noted, laughing. Everyone nodded in agreement.

"Hey Ochaco, I know this is last minute, but can you help me stock up the fridge?" Izuku asked nervously, still getting over the slight heart attack he got when Bakugo almost punched him. This caused Ochaco to blush and awkwardly nod. Izuku smiled and left, following an enraged Bakugo and a worried Kirishima. Everyone slowly dispersed too, leaving you and Ochaco who was still blushing.

"Wanna walk back with me? I'm not too sure where the dorms are from here." You asked, breaking Ochaco from her trance.

"Oh yeah, sure." You both began to walk back to the dorms.

"He's cute." You stated as you two walked.

"Uh what?!"

"The green-haired guy… can't remember his name… anyways, he's cute! Sorry, I just noticed you blushing earlier so I figured you maybe liked him."

"No! Don't be silly, I could never be into such a nerdy, cute, funny, sweet, attractive… AH!" Ochaco buried her face in her palms in embarrassment.

"Well he seems to like you too, right?"

"No way! He never even notices me!"

"He literally just invited you to hang out with him."

"It's just stocking up a fridge! It means nothing to him."

"If I were a guy and I wanted to hang with a girl I liked, I'd take any chance I get to hang out with them… even if it is just stocking a fridge." You chuckled. Ochaco's blush seemed to have gone down and she smiled a little bit as she thought of this.

"Yeah… maybe you're right! I dunno… guys can be pretty clueless though…"

"That is a very true statement, but just try flirting and see what happens."

"Flirting… yeah I'm not very good at that." Ochaco admitted, rubbing her neck.

"Well just try and if you need any help, just ask me. I've helped my friends with stuff like this in the past and it always works… but it's more of like a last resort thing so just try flirting and only ask me for help if you're super desperate."

"Okay…" Ochaco answered, curious as to what you meant. You guys finally made it to the dorms and Ochaco lead you to your room which was bare except for your suitcase and an empty bed.

"Well, wish me luck!" Ochaco joked as she left the room in search of Izuku. You gave her a thumbs up and then went straight to unpacking.

(Time Skip)

It took a few hours, but after various trips to your house and the store, you finally had your room the way you wanted it. All that was left to do was unpack clothing into the closet and dresser. As you began to unpack you heard a knock at your open door. You turned around and sighed as you saw an all too familiar face.

"Hey Bakugo." You greeted tiredly, you already had him figured out.

"I feel like we got off on the wrong foot. You see, I'm not used to being beaten by my own peers, especially when their costume makes them look like they just came back from gymnastics." Bakugo teased, he was obviously just trying to get under your skin and make you mad so that you'd want to fight him again, but you saw right through this.

"You know, I'm not scared of you." You stated, standing up with a pile of clothes to put into your dresser.

"Maybe that's the issue here. What can I do to change that?" He growled, his hands began to spark.

"I'm not scared of you because I have you all figured out. I've even dated guys like you before… Let me guess, you're from a decent home with annoying parents and you constantly need validation in order to feel like your life has meaning. It's kind of sad, but I'll give you validation if you really want it that badly."

"What the fuck are you talking about?!" The blonde asked angrily.

"I'm just addressing the fact that you felt the need to come into my room and ask me for a re-match when it's perfectly obvious that you just can't handle the fact that someone might be better than you. So here's your validation, if you were like twenty-percent nicer and had a less annoying voice then maybe I'd consider dating—"

"SHUT UP! All I want is a damn re-match!" Bakugo's cheeks were slightly pink from your last remark.

"And I said no! Besides, if we fought again you'd definitely beat me." You noted, grabbing another pile of clothes.

"So you admit I'm better than you?" Bakugo smirked, leaning against the doorframe.

"Sure, I've seen what your quirk can do and it's way more powerful than I thought, but that's not the point! When you fight against villains you typically have no idea what their quirks are, so in order to be a great hero you have to be prepared to fight anything. If we fought again it would only prove that you know what my quirk is and how to defend against it. It's not going to change the fact that you lost to me because you weren't prepared for it. Now can you let me unpack please?" You asked, looking up at Bakugo with your bright (e/c) eyes.

"Whatever." Bakugo muttered, leaving. He didn't know how, but somehow you made him feel weak and stupid. You definitely had him figured out, but it still annoyed the crap out of him. He'd get back at you one day though.

You rolled your eyes as you slammed the door shut and finally finished unpacking. The very thought of Bakugo made your blood boil. How dare he tell you that you have no right to beat him! You took a deep breath and pushed him out of your mind, it was time to finally relax now that your room was in order. You walked over to your wooden desk and picked up your laptop, bringing it back to the bed and looking up Netflix to watch some good ol' Parks and Recreation. You played the episode and sat comfortably on your bed until you heard another knock at your door. You paused the episode, grumbled curses to yourself, and prayed that Bakugo didn't come back… for his sake. You opened the door, but were surprised to find a sharp-toothed red-head standing in front of you.

"Hi…?" You asked, unsure as to who this was and why he was here.

"Heh… sorry," He rubbed the back of his neck and chuckled awkwardly, showing off a cute sharp-toothed smile. "I'm Eijiro Kirishima, Bakugo's one and… well only friend."

"Oh lord." You sighed, knowing fully well what was about to happen. "If this is about him wanting a rematch, I swear to fuck I'm gonna—"

"No! Ha! It's nothing like that. I actually came up here to like… compliment you? Sorry, I know that sounds weird, but literally no one at this school has the guts to tell Bakugo to, you know, fuck off." The red head chuckled. You breathed a sigh of relief and smiled warmly back.

"Yeah, he's a huge dick. An attractive dick, I'm not gonna lie, but a huge dick! Not sure why you'd be friends with him… why are you friends with him?" You asked, raising an eyebrow.

"Ha! Remember when I said I was his one and only friend? That's why. The guy has no friends, and everyone should have at least one friend, dontcha think?"

"Yeah, but how do you put up with it?"

"To be completely honest, he's not that bad of a guy once you really get to know him. He's definitely rough around the edges, but deep down he's got a soft side, you just have to keep bothering him until he gives in!" Kirishima laughed, causing you to chuckle too. You liked this kid, whoever he was and you knew it was always a good idea to make friends, especially on your first day when you knew no one.

"I can't imagine him being nice, but I'll take your word for it. I'm (Y/N) by the way." You stated, holding out a hand.

"Nice to meet you. I kinda already knew your name because you announced it in front of everyone while simultaneously taking down one of the top students in the Academy. Pretty badass if I do say so myself!" He shook your hand, smiling. "So how are you settling in? Hopefully Bakugo didn't traumatize you too much."

"Oh no, he just harassed me about how he wants a rematch despite me telling him no." You explained, rolling your eyes, but smirking.

"Yeah… I heard about that. He was using my punching bag for a while, yelling about how pissed he was. Typical Bakugo stuff, nothing to worry about. He's wanted to kill Izuku Midoriya for a while now, but Izuku still lives so…" Kirishima scratched the back of his neck again, trying to think of a different topic to talk about.

"Have you ever heard of a show called Parks and Recreation?" You asked, breaking the silence.

"I think so, I heard it's really funny."

"I'm watching it right now on my computer if you want to watch it with me? I'm not sure if you're very busy." You asked, opening the door more for him to come in.

"Sure! Got nothing else to do except train, but I do that every day, and it's not like we get days off very often," Kirishima explained, walking into your room. You leave the door open, just so that no one got the wrong idea when passing by and hearing the two of you laughing. Kirishima plopped on your bed and waited before you sat next to him to press play. You binge watched a full season before you realized it was getting late, got bored, and stood up to leave. Kirishima agreed and left with you, saying he needed to check to make sure Bakugo hadn't destroyed his room while he was gone. You laughed and made your way down to the main floor where you knew you'd find the refrigerator since that's where Ochaco said it was. You glanced around and rounded a corner until you saw something that made you want to squeal. Ochaco was sitting next to Izuku on a couch, talking and eating popsicles. Had they been talking this entire time? You were so happy and didn't want to ruin their moment, but also really wanted a popsicle now that you saw how good they looked. You decided to just go get one and walked to the fridge. Ochaco noticed you and gave a little wave. You tried to contain your excitement as you waved back, grabbing a popsicle from the fridge and popping it in your mouth.

"You can sit with us if you want." Izuku offered, taking notice of you and motioning to the couch across from them. You looked over at Ochaco to make sure she was okay with it and she nodded, letting you take a seat.

"So how was stocking the fridge? Sounds pretty exciting." You joked. They both awkwardly laughed, making you want to laugh because of how weird they were acting.

"Yeah, pretty crazy." Ochaco added.

"I heard you talked to Bakugo again, how'd that go?" Izuku asked, popsicle still in his mouth.

"It went fine. Told him to fuck off, got complimented by Kirishima, and then watched an entire season of Parks and Rec. All in all, an interesting evening. How's your guys' evening been going?" You asked, prying to get more info on what they did. There was little to no response, just awkward pauses as both tried to respond at the same time, got flustered, and then tried again.

"Well, I'm gonna head to bed because I am tired." Izuku said, clearly giving up and slowly backing away before running to his room. You and Ochaco watched with an eyebrow raised until he was gone.

"What's with him?" You asked Ochaco who was looking at the ground sadly.

"The same thing that's with me… we're both just too awkward around each other. Sometimes it's like we're best friends, but if I get too close or say something that indicates me liking him, he completely closes up. Maybe he doesn't like me."

"You just described what an awkward boy looks like when he has a crush. Izuku, based on the other guys I've seen here, is like the most awkward man I have ever met. He definitely likes you girl." You said reassuringly.

"Really?"

"Totally! What did you guys even talk about for so long?"

"You, Bakugo, All Might, and how he's nervous about what's going to happen with you and Bakugo. Lots of talk about you and Bakugo. That's gotta be annoying since that's all people are ever going to ask or talk to you about. Hopefully he'll just keep to himself and not bother you anymore since it would only hurt his reputation."

"He has a reputation?" You snorted.

"He wishes!" Ochaco burst out laughing. You both laughed for a while, making fun of the angry blonde until he walked past. You both watched in suppressed silence and he walked by, glancing over, glaring, but continuing to walk. You both breathed a sigh of relief as he walked away.

"At least he seems to be over the whole re-match thing." You said quietly.

"Yeah, no kidding." Ochaco added. You finished your popsicle before getting up and heading in for the night.
