Kilers and Quirks (MHA x Male OC)

Why?

Momo

"K-KIRA!" My heart stopped as Kira's body was laying down, His body was nearly motionless as we sat in the rain.
Chances are that help wouldn't arrive in time for Kira, I'd be all my fault
"Momo" Jiro said, I dragged my eye's away from Kira
"He's not..." She trailed off.
The whole class was waiting in silence. "Kira you bastard"
"......" It looked like he wanted to say something but all that came out was his breath, Long and drawn out. Kira stretched his arm out but dropped it down before it touched me
"Where are you? Im so lonely. P-please I don't want to be alone" Kira said, A single tear falling down his face, It was washed away in the pouring rain
"where are you. Please I can't be alone anymore, Don't leave me" Kira's face started to fill with tears
"KIRA" I shouted at him, Hoping for him to hear me
"IM RIGHT HERE" I said scopping him into my arms, He felt colder then he should be
"I want to see you one last time, Momo..." Kira's head fell back as his voice drained away
"I...Love you" Kira's eye's fell closed as I screamed at him, Not saying anyone thing just wanting him never to leave me
"KIRA" Kirishma yelled ay Kira grabbing his shirt, Kirishma who I'd never seen cry was balling his eye's out.
A distant wailing filled the mostly empty night, Kira even if he could get to a hospital he'd most likely die
"Don't die. Kira" I said knowing that I couldn't change it, Kira's body was picked up and loaded into the ambulance that had just got here
He didn't move as he was laid onto the small bed in there.
The doors shut as it skidded away, The lights on top of it slowly faded into the dark
"......" I couldn't even bring myself to breath, it felt like my lungs were burning.
My eye's were filled with tears as I started to breath again. My face started filling with tears as I fell onto my back
"KIRA" I screamed his name, I just wanted him back. I'd never let him go

Kira

"It's kinda depressing isn't it? That I could die just from falling off a clif, When I was a kid I always thought I'd die in some cool way, Like a shoot out on top of a train but no. Im dying from falling, what a lame way to die.
But who knows maybe my next life I'll make it up be a good student and a good person in general, Maybe I'll even become a hero in that life
And I do hope that Momo doesn't stay hung up on me and find someone that she loves, That'd be nice
And I really do hope I could at least have made someone happy but all I feel like I did was cause people pain but that might be me just getting into my own head" 
"Sir?" I looked around in my own dark world but couldn't see anyone that the voice belonged to
"Who said that" I said not really caring for the answer. But it was all that I could care for
"Well well well. You really have changed my little Kira"
"And you might be"
"Ehh, You don't gotta know that" I shrugged and moved on, Not lingering no the voice calling little Kira, I get im small but to call me little was a bit odd
"Alright, give it to me straight. Am I dead" I said bluntly 
"Nope" The voice sounded like it popped it's lips as it said nope
"Well then. Im lucky then" I said shrugging, or at least feeling like I was
"You really are"
"well, I've had fun and I'd like to go back, can I?" I said, Almost not caring for the answer, I don't hate life but sometime it'd be easier if I was just dead, Or just not being anything of importance to anyone. But I have a dream to make, Too come true
"Ahh, LOL. I completely forgot, Yes right away" I heard a snap and my eye's flashed open as I felt cold envelope my body, It wasn't a bitter cold but a comforting one.
I looked around at the room I was laying down in, I was hooked up to a lot of different machines, From one's that were monitoring my heart rate too other things I couldn't recognize
"KIRA!" I jumped at the voice. I looked for it and saw a girl with blue hair sitting at my bedside, she had just brought her head up from laying down on my bed, She exhaled and looked back at me. It felt like I was going back to the good old days. Just seeing her face made me beyond happy to be back, Her hair, face, eyes made me comfortable even in my dull pain.
"Nejire..." I said, she seemed relieved that I could remember her name.
"You had me worried" She said looking at me. I dropped my head back onto my pillow and a small laugh escaped my lips "I messed you over these years, I really did"
"Why?..." I looked over at Nejire, Her eye's were closed and her hands curled into fists on her lap
"Why didn't you come find me sooner? You do remember what we promised. Don't you?"
I nodded my head "Well. At least im here now" I said reaching out for her
She took my hand and put it onto her face closing her hands over it I could see a smile from across her lips, as she sighed
"Yeah. That's all I wanted to hear from you, That your here with me" I could feel tears welling in my eye's, I was so relieved that she remembered me and our promise
