To My Explosive Heart

Bomb time

A day like any other
"Just do what I told you to do" each second of hesitation meant one less victim of my stupid quirk. I guess not everyone can blow themselves up? I was like a reusable stick of dynamite! I won't get into details but my brother frickin loves it! Only problem is that my clothes burn when I do it leaving me naked which isn't ideal but little perk with the power came the ability to vanish before the smoke cleared. Of course that meant my Katsuki has seen me nude once or twice but it's not like he stared. He'd normally toss the duffle bag of clothes while looking away before fully turning around.

My original plan for life was either to go into Law or some art college but then I got really sick, so sick they didn't think I'd make it out of the hospital alive which lead to Katsuki viewing me as nothing more than his 'precious' and 'defenceless' baby sister. He learned that I could die at any moment which partially means he lets me do what I want but nothing 'too dangerous'. So I attended classes during the week before going home to his little villain hideout.

Our parents threw me out when they found out I wasn't straight, when I came out as pan. Of course once katsuki found out, he practically came and swept me off my feet into his villian life. There I met Todoroki and Izuku, his partners in crime. Turns out something went wrong with his class at UA - so bad they all became high class villains. Before all the law and art stuff, that was my dream as well as it was Katsuki's, then he found out and got really mad and protective. So mad it made me go off it completely.

I closed my eyes clenching my fists crying out as I detonated my body instantly killing all in range also causing me to temporarily black out. Once my body rebuilt itself, I sprinted for cover not daring to look back at the damage "your range is getting bigger"

I jumped at Kacchan's voice as the bag landed at my feet "Katsuki! Don't look!" He rolled his eyes before doing as I asked "it's nothing I haven't seen before, dumbass" I got changed quickly before slinging the empty bag over my shoulder and folding my arms "doesn't matter. I'd still prefer you not seeing" he raised an eyebrow "Mom literally made us take baths together" I hit his shoulder "Yea but not for long. Let's get this over with" he slung his arm around my shoulders in a possessive manner and we wandered back through the carnage, this was his favourite part.

Once we got back to the hideout, he didn't leave me like he usually did. Instead he just stood leaning against the door studying me as I practiced my art skills "Spit it out already" my head jerked up confused that he was still there "What?" He gestured to my hands

"you've been staring at that blank page for just over half an hour now...what's going on with you?" i shook my head muttering my next words "its nothing" annoyance spread through his expression like wildfire "Would you quit the muttering!? You know I hate that" I threw my pencil across the room "its art block! just art block. Sorry, you probably have somewhere to be"

I watched his eyes flicker to the clock "not right now" he picked up the pencil I tossed and took my hand wrapping my grip around the utensil "how about I say a word? you draw the first thing you think of?" I agreed intrigued as id never seen this side of him before

"Domination" I thought for a second before sketching a globe "Villain" I quickly did a rough draft of my brother earning a grin from him "Liar" I drew a little person with crumbling brick walls around him as he cowered on the floor in a ball.

He opened his mouth to speak again when there was a knock at the door which neither of us were expecting "You said you had nowhere to be?" he gave me a cautious look as he stood putting on a tough front "I don't" I put away my book before he let whoever was on the other side in "It's open" one of his 'minions' peaked from behind the door almost scared "what is it?!" he jumped as he studied the scene before him "Izuku Midoriya and Shoto Todoroki are here, boss"

He pointed a finger at me "Stay" I nodded watching him leave as i continued to draw things that came to mind. I started drawing an apple in great detail as loud voices rose up, something tells me I blew up in the wrong place?

In my defence, Katsuki told me where to stand and when to detonate...I was just a girl following orders. It wasn't long before the sound of explosions filled the halls "Why don't you dumbasses come back tomorrow?! 5:00!"

my brother's voice grew nearer the door before he burst in and shut it behind him "I blew up the wrong place, Didn't I?" he shook his head pinching the bridge of his nose "Wrong time somehow" I didn't even look up from sketching myself in the hospital bed with tubes in me "They want to talk to me, don't they? that's why you 'asked' them to come back an hour after I finish class"

He stared at me blankly "i did what I could" I nodded "its fine. you don't mind me detonating in your lounge right?" he opened his mouth then closed it and opened it again "once I move the lounger" I peered over my shoulder as I hid my working knowing he wouldn't approve "What did you draw?!"

I shrugged it off nervously pinning the book face down on my bed "Oh nothing, just an apple" he leaned down to my level driving his knuckle into the duvet "what did I say about lying?...Liar" that grin appeared on his face again.

I took it a step further and sat on the book "We both know you won't approve, so can we just move past this? and forget I drew anything?" he shook his head as I nodded but what I didn't expect was for him to shove me backwards, lift my legs by my ankles, grab the book and start flicking through it until he found what I was trying to hide

"We agreed to never speak of that again...great detail for someone who could only see in first person" I could see it hurt him to look at it "Technically we still haven't and never did 'speak of that'"

He chuckled sadly "a picture paints a thousand words, Tachi. Thought you'd understand that better than anyone?" I sighed "there was a mirror at the end of the bed, where mom or you sat. I keep remembering looking in that mirror and just seeing myself wasting away and deteriorating"

He looked away from me "you were fighting for your life, that's not gonna make someone look great" I shook my head "no I wasn't. I was ready to go, I was ready to die in that bed. I just wanted the pain to stop, anyway possible...why do you think they put me in a ward on my own with quirk dampening fluids in the tubes?"

He chewed the inside of his cheek "you tried to detonate yourself...didn't you?" I nodded "all I could do was make myself smoke a little bit, they panicked" he started doing the exact thing he hated, muttering.

"I was prepared to die alone" he shook his head "I wouldn't let that happen" I stood holding him forearms "specific visiting hours, remember?" He scoffed "that hag never let us forget" I looked down smiling sadly "you used to sneak in after hours every now and then"

He raised an eyebrow "I swear if I keep finding those two dumbasses trying to sneak in here, one more time-""well I thank you for your protection and hospitality, you've done more for me than I've done for you" he chuckled "I appreciate the mini portraits you do now and then"

It was rare we got to act like real siblings, he was always conversing with dangerous people so I rarely saw him during those times but he only brought me into it if he trusted those people, which was hardly ever. Except for being a human bomb, my life was actually pretty normal. I had friends, I had school, I had homework, I had sibling rivalry but what I didn't have was love.

I didn't really want it to be honest, I'd spent enough nights comforting friends from heartbreak which normally left me feeling sick the next day due to too much ice cream and lack of sleep. This obviously would piss off Katsuki but the surprise came when he'd wander in with soup or something simple like that. I admit he's a softie around me, villian or not.
