A/N: Transgender! Kiri! So, this was requested by SoMuchAnxietea when this book was taken down. For me only...? So, I wasn't having that, so I made another book. Then this showed up again, so boom! Another thing, I know little to nothing about binders, dysphoria, etc. I hope you guys don't expect me to know too much, but I'm gonna try and make this believable as possible. To make it easier on myself, though, this isn't in Kirishima's POV. It's in Bakugou's. I apologize if this isn't what you were thinking of when it came to your request, but I'm still gonna try hard to make it good. I hope you all enjoy!

BOOM BOOM BOOM BOOM'S POV

"Oi, Shit for Brains! Could you open up? I've got out shit ready for our study session!" I yelled threw the door, lightly knocking with one knuckle.

"Uh, sure, bro. Gimme a sec." Kirishima said from inside his room.

He opened up with one of his signature baggy shirts and a pair of baggy sweatpants on. His hair was being held up only by a blue tie dye bandana.

"Hey, Bakubro!" Kirishima said, opening his door further.

I noticed his movements were pretty stiff, so I decided to tuck that into my mind until it came up again.

I walked over to the small table in his room and sat down.

He walked over and just stood there like a fucking dunce.

"Oi, sit down."

"N-no. I'm cool. I'll just stand for this lesson." He said, his breathing shallow and quick.

"Dude, are you okay?"

"I'm fine. Let's just st-- fuck!" Kirishima cut himself off with a hiss, his hands flying to the side of his torso.

"Kirishima, are y--" "I'm fine, man. Just... gimme a sec. It'll go away." Kirishima said before sitting down at the table.

He was grimacing, his breathing much sharper.

"Kirishima, hold on." I said, putting my hands where his were.

I felt his breath hitch and I paused.

"You okay? I feel bandages." I murmured.

"YUP! FANTASTIC!" Kirishima tried scrambling away, but he paused again and let out a choked noise.

"Kirishima, what's wrong? And don't even think of fucking saying nothing, you dumbass--" "I'm fine! The bandages are just... tight."

"Is that all?" I asked. "Why didn't you tell me, dumbass! Here let me--" "No! I can deal with it. No big."

"Kirishima, you're breathing like you have five spears stabbed through each lung."

"Wouldn't I die if that happ-- MOTHER OF FUCK!" Kirishima curled up, shuddering and grimacing.

"Let me fucking he--" I went to grab his torso when I missed and grabbed his chest.

I could feel the bandages, but I could still feel his chest under them, and the small protrusion.

If a male bandaged his chest, there would probably be no protrusion, but there was on with Kirishima.

(A/N: I don't know this for sure, just roll with it. Like I said at the beginning, I have no fucking clue what I'm fucking doing. I did a bit of research on a few things, but that's it.)

"Eijirou..."

"... yeah?"

"Are you transgender?"

Kirishima looked away, ashamed.

"Eiji... why didn't you tell me?"

"What?"

"WHY DIDN'T YOU FUCKING TELL ME?!"

"I... I..." Kirishima was panting, his eyes wide and glossy.

"DID YOU THINK I'D TREAT YOU ANY FUCKING DIFFERENT?!"

"N-no, not a-at all. I juh-just--"

"SO THEN WHY NO--" "I WAS FUCKING SCARED OF THIS!"

I paused before blanching.

I just fucking yelled at Kirishima.

"Kiri, I--" "I WAS SCARED YOU'D HATE ME! I WAS SCARED YOU'D CALL ME SOME SISSY TRANNY FAGGOT, BECAUSE, GOD DAMN IT, IT'S HAPPENED BEFORE! I'VE MADE FRIENDS WHO'VE THOUGHT I WAS SOME SORT OF FUCKING PSYCHOPATH FOR THIS!"

Kirishima had tears running down his face at this point, his face red.

"Jesus fucking Christ, I'll be right back." He scoffed, walking into his bathroom.

I stood there, guilt thrashing throughout my body.

I just yelled at Kirishima.

I overreacted.

I shouldn't have screamed.

I shouldn't have gotten offended.

I shouldn't have fucking done anything.

Kirishima came back out, the bandages rolled up in his hand.

"Why are you still fucking here? Get out." Kirishima snarled.

"Wait, Kirishi--" "What, aren't you disgusted? A guy with tits? Who'd have fucking thought? The guy who cares about being manly is actually a fucking girl."

"Kirishima, I'm not disgusted. I was just surprised." I sighed, running a hand threw my hair. "I really shouldn't have yelled, and I'm sorry."

Kirishima's face softened a bit.

"Come here. Can I hug you?"

"Would it be weird to feel--" "Look, I hear what you and Kaminari joke about, and I bet you my chest is still bigger than yours. I don't care if you don't."

Kirishima laughed a bit before hugging me. I rubbed his back as I felt a wet spot grow on my shoulder.

"Hey, look at me."

He looked up at me. "I'm sorry, this isn't manly."

"Listen, you are the manliest person I fucking know, you bastard. Mulan is the second."

"Mulan? What does sh--" "What did Mulan do?"

"She got down to business to defeat the Huns? What does this have to do with--" "What was Mulan's gender. Not the one she posed as, the one she went by otherwise."

"Female-- oh."

"What I'm saying is it doesn't matter what's in your pants or what isn't. You are the gender you feel comfortable as. Whether you have a female body or not, as long as your gender is male, non-binary, gender fluid, fucking whatever, you deserve to be called the pronouns you'd like." I said. "I assume he / him?"

"... yes."

"Okay then. And is Eijirou your chosen name or have I been deadnaming you, because I will stop immediately, if that is the case."

"Eijirou is my chosen name."

"Okay. Are you on testosterone already?"

"Yeah."

"Awesome. Want me to see if Yaomomo can make you a binder?"

"You don't have to--" "I want to. I don't want you to bandage yourself so tightly that your body suffers."

"If Yaomomo is okay with it."

"Okay. What's your cup size?"

"Katsuki!"

"Hey, it's for the binder!"

"Fine... C."

"Okay."

"One more thing before you go."

"Yeah?"

"I like you."

"Me too."

"Could... could we maybe... be, uh... together?"

"Of course. I'll be your boyfriend if you'll be mine."

"I would love to."

A/N: And here she is! Keep the requests coming, y'all! I love them! This one was fun, even if I knew very little. But here she is. I do hope you enjoy it, SoMuchAnxietea! Alright, I'll see ya! - Septic / Spark
