Eimi's POV

I woke up to my alarm and quickly turned it off. I sat up and stretched my arms before I heard a satisfying pop. I sighed only to quickly stop. I then opened my eyes and looked around. Wait a second. This isn't my room, and I don't remember sleeping in Katsuki's room last night.

I then looked at my hand and paused.

"What the-" I started but quickly covered my mouth with my hands. That was Katsuki's voice. Oh my god, am I in his body? I quickly got up to run to the bathroom but stopped and looked down. Looking back up at an imaginary camera I blinked.

"Yep. I'm in his body."

I still continued to the bathroom anyways and looked in the mirror. Spiky blonde hair, ruby-red eyes, defined muscles, and a strong jawline that can turn into the cutest chubby-cheeked face in a matter of seconds. Yep, I was now in Katsuki's body. Does that mean he's in mine as well? Most likely.

I walked out of the bathroom to hear a knock on the door. I stepped over and unlocked it before opening it. I looked down to see me, or well, probably Katsuki, standing right in front of me. A scowl on my face was a weird sight to see, but I pushed my way into the room and past me. No, Katsuki, gotta remember it's Katsuki, not me. Don't start talking in some weird and slightly wrong version of Third Person, me.

I turned around after shutting the door to see Katsuki sitting on his bed. My hair, or well, I guess now his hair, was in a neat long braid down the center of his back. He was always good at doing hair, I bet he could become a hairdresser if he didn't want to be a hero. He turned to look up at me and I opened my mouth only to get stopped by him.

"How are we gonna do this?" He said as I looked up in thought.

"I don't know, tell Dadzawa?" I replied before I found myself bursting out in laughter. "Sorry, it sounds so weird for your voice to say Dadzawa-pfttttt-- I can't, I'm sorry!"

I bent over trying to get myself together while I heard a huff of annoyance. I calmed myself down from my laughing fit to look back up at Katsme. That was the new way I was going to identify Katsuki now. Katsme. Get it, because Katsuki mixed with me- I'll stop now.

He stared down at me before falling back on his bed. I tilted my head at him in question before he brought his hands up and held my boobs up slightly.

"How do you even function with these, my back hurts so fucking much and it hasn't even been twenty minutes." He complained and my eyes trailed down to his chest. 

I put my hands up to his chesticles before cupping them lightly. I looked at him while my hands stayed in place and stared at him blankly.

"Yours aren't that much smaller than mine so you should be used to it already, so I don't see the problem here."

"What did you just say?!" He screeched and I covered my ears. Is my voice really that high-pitched when I scream?

We then heard a knock on the door and I backed away from Katsme and to the door. When I opened it I was surprised to see Kiri and Mina.

"We have a slight problem..."

Kiri then pushed in while dragging Mina through the door. I didn't think much of it as they both are pretty similar in personality and are both in the self-proclaimed Bakusquad. The only difference I saw when they sat down was the fact that Mina sat where Kiri would usually sit and Kiri sat where Mina would usually sit.

"Whadda want?" Katsme growled and I quickly smacked him up the side of the head. Which in turn made me cringe because I would definitely be feeling that when we changed back. My usual hit wasn't that bad but I'm not used to all this muscle, so I'm not too sure how that 'small smack' went.

Kiri's eyebrow went up before he exhaled and laughed.

"What?" Both me and Mina questioned before Kiri waved his hand until he stopped laughing.

"Sorry, I should clear this up first. I'm Mina, actually, we got body switched and I'm guessing you did too?" Kiri who I now knew was Mina explained. My eyes lit up and I quickly hugged her.

"I'm not the only one!" I whined and Kiri who was in Mina's body looked scared.

"It's so weird seeing Bakubro's being do that." He mumbled while Mina hugged me back.

We heard a groan and pulled away from our hug to see Katsme sitting up while rubbing his back. He stood up roughly which caused his braid to come back and whip him in the face.

"How do you deal with this shit!" He yelled and I flattened myself to the floor to hide from him.

Kiri then jumped up and held him back with a sigh.

"We should probably go tell Mr. Aizawa about this." He said and Mina quickly nodded before pulling me off the ground. She had a look of surprise before she quickly looked at her arms.

"Damn, even though you're in Bakubabe's body, I can still lift you up so easily."

"Wait, I wanna try!" I jumped excitedly in my spot and quickly grabbed Mina by her shins before hoisting her up and onto my shoulders. I stood there for a second and basked in the glory of wide shoulders.

"What a difference..." I trialed off and Mina laughed.

"Since I'm up here, might as well go!"

"Aye, sir!" I smiled before opening the door and skipping out. (Any Happy stans out there?)

Shoto's POV

Izuku and I were walking down the stairs to the main floor to tell Mr. Aizawa about our predicament when Bakugo came jumping down the stairs with Kirishima on his shoulders. Izuku paused and horror was in his eyes.

"W-what happened to Kacchan?" He asked with a shaky voice while pointing forward at the boys running down the hallway while laughing. I turned my head and looked up at him before shrugging my shoulders. It was a little strange to look up at him, considering our normal height difference, but something I could learn to get used to for a day. At least I hoped it was only going to last a day.

Just as we were going to continue our way down the stairs, Eimi came crashing into the wall with an ice trail behind her. She swore before Mina came and crashed into her while the ice trail melted because of her acid. Izuku and I looked at them questionably before Eimi made eye contact with me and scowled. I swallowed my spit and looked at Izuku before looking back at Eimi. Did something happen between them that is making Eimi look so... Bakugo?  I mean, they are dating so maybe she's picked up some traits from him.

"Hurry up slowpokes!" I heard Bakugo yell from down the stairs as Eimi groaned and pushed Mina off of her before stomping down the stairs while mumbling profanities left and right. 

"Sorry 'bout that." Mina waved slightly before quickly following after my sister, but tripped over her feet and tumbled down the stairs, though not before taking Eimi down with her.

"There's something definitely wrong here today." I said before grabbing Izuku's hand and continuing down the stairs to Mr. Aizawa.

It took us only a few minutes before we got to his door and Izuku knocked.

"Why so many disturbances." We heard our teacher mumble from the other side of the door before opening it.

"I'm not even going to ask, just come in already." He said in a bored and annoyed voice before we walked in to see Kirishima, Bakugo, Mina, and Eimi all sitting on the couches in Mr. Aizawa's room.

We all made eye contact before we got pushed into chairs beside the couches. Kirishima waved at us at then leaned back to whisper something to Bakugo. What happened next terrified me. Bakugo looked at us before his eyes widened and he... smiled. Not only did he smile at us, but he waved back then laughed at what Kirishima said.

"I'm guessing you all came to me because of the same thing?" He tiredly asked and the four others nodded while Izuku and I sat there confused. Everyone's eyes landed on us and Izuku started to squirm. 

"That answers that! Sho would never squirm like that so it's gotta be Zuzu!" Bakugo exclaimed and my eyes widened before I pointed slightly at him.

"Eimi?" I asked and watched as Bakugo nodded and gave out a peace sign, one of Eimi's signature greetings. Izuku fell back into the seat before letting out a sigh of relief.

"Thank god." He mumbled before Mr. Aizawa cleared his throat which caused us to look at him. He sat up in his chair before pushing his hair back.

"Okay, so just to clear things up. Kirishima is in Mina's body while she's in his, and Eimi is in Bakugo's body while he's in hers, and lastly, Midoriya is in Todoroki's body while he's in his."

We all nodded before he sighed.

"Well, it looks like only you six have switched bodies so far. I also assume it's because you guys are couples, respectively, and one of you in each pair must have gotten hit with a quirk that did this to you or something like that." He told us while Izuku raised his head before speaking up.

"W-well, Eimi, Ashido, and I were all sent out to get more dishes for the dorms since Kaminari keeps breaking everything in the kitchen. Maybe we got hit with a quirk and didn't know it?"

"Oh, I remember that!" Ashido in Kirishima's body recalled while having her finger up to her chin. Eimi in Bakugo's body nodded along with her while we all started to think.

"Should we try to act like each other for the day-" Kirishima started to say when he was quickly cut off by Bakugo.

"No way in hell, Shitty Hair."

"I don't care what you do, just get out of here already." Mr. Aizawa sighed tiredly before pointing out the door. "I'll talk to the old lady and see what she thinks of this, but for now, don't cause too much trouble. Okay?"

"Yes, sir!" Both Mina and Eimi exclaimed while saluting our teacher. Bakugo grabbed Eimi's hand and quickly pulled her out while Mina locked arms with Kirishima before following after the strange couple.

I slowly got up and helped Izuku out of the chair before we said our goodbyes to our teacher and left.

"I'm scared for what is to come today." Izuku shook his head and I could only nod in response.

Katsuki's POV

This was going to get tiring, fast. I don't want to have to deal with questions from our annoying as fuck classmates and I definitely don't want to deal with teasing from soy sauce and discount Pikachu. At least Shitty Hair and Racoon eyes are going through the same thing so they won't be that annoying.

"Sukiii, I want eggs. You should make me some." Eimi whined from behind my back and I groaned before huffing and turning around. I came face to face with my body's chest and growled before looking up. How does she even live with being this short?

"Don't wanna."

"But I'm hungryyyyyy." She pouted while starting to slump and I knew there was no getting away from it now. As soon as she slumps the only way I could solve the problem was to either comply with her needs and wants or to pick her up and take her to my or her room. I'm not one to say that she's weak, she's far from it, but I don't want to have to strain and pick her up while she's in my body. I know full well that she can lift me up, but she has to do it in a certain way to get the most out of her build while I only have to grab any part of her and throw her over my shoulder and go on my way.

This is the only way and if I do this now, I have a better chance of not seeing any of our other classmates.

"Fine." I grumbled before plowing to the kitchen and quickly grabbing the stuff I needed to make eggs.

"Yay!" Eimi exclaimed before jumping to sit on the counter. I quickly turned my head to her before pointing at the floor by my feet. She turned her head before I sighed.

"You are to sit right here and be quiet. I don't want any of our classmates to find out about this and we have a better chance of getting through this shit if you stop acting like yourself while in my body. But I know there's no way for you to do that so just sit and be quiet." I sternly stated and she nodded her head before coming to sit beside my feet.

I started to crack the eggs and put them in the pan as Eimi started to pat the floor lightly. I slightly nudged her with my foot to stop and she sheepishly looked up at me. I looked blankly back at her before continuing to cook the eggs.

Just as I was about to plate the eggs, one of the worst things could've happened.

"Uh, Bakugo, why are you sitting on the floor?" Kaminari's voice called out and I froze in my spot. I looked down at Eimi to see her face in a slight panic while looking up at me for something to do. Crap, how am I going to do this?

"You guys good? I know you're dating and all but staring at each other like that is kinda out of your character."

"I, uh-" Eimi started but I cut her off and did the best Eimi impression I could muster.

"Suki wasn't feeling well, so I'm making him some eggs and taking him up to my room for the day." I internally cringe at what I just said and hoped to god it was convincing enough for that dumbass Pikachu.

"Oh jeez. I don't want to have to deal with a sick Bakubro, good luck dudette! I'm getting out of here." He quickly said before backing off and leaving the room.

I sighed before finishing up with the eggs and quickly grabbing Eimi's hand and dragging her up to my room. She opened the door while I held the plates and we walked in. I watched as Eimi flopped onto my bed before screeching into the sheets.

"What's your deal?" I questioned before she looked up at me.

"I didn't know you could act so much like me, it's scary." She mumbled before an irk formed on my head.

"You know. You're really pushing it today."

"I'm sorry!" She yelled before quickly hiding under my blankets.

I only sighed at her before sitting down on my bed and patting her back. She popped her head out and I showed her the plate with the eggs she wanted so bad. Her eyes automatically brightened while she took the plate from my hands. I grabbed my plate before sighing.

"I hope to god this shit doesn't last too much longer."

"Itf's nof dat bad, Suki." Eimi said while stuffing her face. I only rolled my eyes at her before starting to eat my own meal.

Aizawa's POV

Do you know just how many times I have groaned just this morning? Or sighed even? I'll tell you, it's a lot, even for me, and that's saying something. I didn't want to have to deal with anything today since it's the weekend and one of my rare days off, but of course my students, or better said, problem children, have to get hit by some random quirk.

I got off my bed before sighing once again and walking to the door. Opening it I saw Bakugo drag Eimi off to the boy's side of the dorm. Which would have been a much weirder sight if I haven't seen what Eimi could do when she's mad. I'll tell you one thing, that kid is truly frightening.

I ignored my other student's chatter and banter from the common room and just left the building. I had to go and get some paperwork from the main building anyway, so I can just stop by the old lady's room to tell her of this problem, and hopefully, she has some way to see how long this is going to last. 

Once I grabbed my paperwork, I started down the hall to the old lady's room. I knocked on the door before sliding it open. Recovery Girl turned in her chair before she smiled.

"Aizawa, is there something I could do for you this morning?" She asked as she placed a pen down on the desk. I sighed before shutting the door behind me.

"Yeah, something happened with six of my students." I stated blankly.

"Oh dear, what is it this time?"

"They have switched bodies with their significant others. Eimi with Bakugo, Shoto with Midoriya, and lastly Kirishima with Ashido."

The old lady just looked down at her watch before shaking her head. She hopped off her chair before walking over to me.

"I got a call the other day that a quirk accident happened at the plaza with a couple of our students."

I cocked my eyebrow as she said this but let her carry on with was she was saying.

"The person whose quirk went haywire said that it could last for either 24 hours or a week. We just got to hope that it is the lesser time, or we'd be in some trouble for when classes start back up."

I only blinked at her before looking up at nothing in particular. This is going to be a long day.

Eimi's POV

Katsme got up to use the bathroom after we finished eating and I was about to fall back into the bed as I got a call. I turned my head to see it was Dadzawa calling. I shrugged and picked up the phone, hitting the answer button and putting the phone up to my ear.

"'ello there mate." I said and I heard a groan of agony on the other line.

"Never say that when you are stuck in Bakugo's body, I never want to hear that sentence in his voice ever again."

"Your choice, I'm fine with it either way. What did you need?"

"Right, I've figured out how long you might be staying in this configuration." Dadzawa said while I could see him shaking his head.

"And??" I questioned before he replied.

"You could be stuck like this for either 24 hours or a week."

I just stared at the floor in shock.

"Well, shit."

"My words exactly." Dadzawa mumbled. "Well, good luck and don't break anything."

And with that, Dadzawa hung up and just left me with having to tell Katsme the news, and I guess the others as well. Just then, the man in question came stomping out of the bathroom.

"Guess what I just found out." I stated as I would normally as to not rile up the being in front of me.

Katsme looked at me and gruffed, letting me know he's listening to what I had to say.

"We could be stuck like this for either a day or possibly a week."

The whole room seemed to go dead silent and I only continued to stare at Katsme while what I said processes in his head.

"I'm going to kill whoever did this, bye." Katsme blankly said before walking out the door. I started to freak out as I scrambled off the bed and out the door after him.

"We can't go killing people! And don't you want this to be kept a secret!" I yelled after him but he continued to stomp down the hall. I quickly looked around to see if there was anyone around before running back into his room and grabbing one of his pillows.

"Katsuki!" I called out to him and he stopped before turning around. His eyes widened slightly as I held his pillow hostage. I'm assuming that activating his quirk would be the same as mine, though I wouldn't know how to hold back how much explosion would actually happen.

"You wouldn't."

"Oh, but I would! So you better come back here or the pillow gets it."

You see, this isn't just some ordinary pillow. This pillow is made out of two of our old shirts, shirts that we wore on our first date that no longer fits both of us. I made it for his birthday and even embroidered our initials on one side and 'I love you' on the other. He hasn't taken it off his bed since.

Just as I saw him start to move back to me, I felt something strange flare up in my body. I thought that it was going to be us returning back into our own bodies but I was wrong as I sneezed instead.

I opened my eyes to only furrow my eyebrows. This wasn't where I was standing. I then looked down to see I was no longer holding the pillow and quickly looked up to see Katsuki staring at the pillow in his hands. He quickly turned and went into his room.

It was then that a door was opened and I turned to see who it was.

"Why are you crying, Eimi?" Shoji asked me and I lifted my hand to my cheek to indeed feel tears present. I know that I wasn't feeling emotional recently, but then it hit me.

"I'm sorry, I have to go!" I squeaked before running down the hall and into Katsuki's room. 

There I saw him sitting on his bed while hiding behind his special pillow. I shut the door behind me and froze when I heard a small sniffle. My heart just about broke and a frown formed on my face. I slowly walked over to the bed and sat down before grabbing Katsuki's head and pulling him towards me.

I buried my face in his hair and hugged him tightly.

"I'm sorry." I mumbled, my tears starting to flow from my eyes. "I didn't think that it meant that much to you..."

Katsuki then let go of the pillow to switch his grasp onto me. He nuzzled his face into my chest before taking a deep breath.

"Don't you go crying too." 

I could only softly smile as my tears continued to stream down my face.

"You and I both know that I can't stop it now." I sadly laughed while Katsuki switched our positions and now he was holding me in his arms as I cried, his tears already gone.

He pet my hair as I turned to grab around his neck.

"I'm sorry." I mumbled again and he only sighed.

"I know, I know."
