Vigilante (Bnha x OC)

Chapter one: My little insomniac

Adrenaline surged through my veins, my heart thundering in my ears, heart pounding just like my feet against the roof of this seven story building. I skidded to a stop and turned around.
" You have no where to run Edge, give up." Eraserhead said, glaring at me through his yellow goggles. I rolled my eyes.
" Oh no, the all mighty Eraserhead has me cornered what will I do?" I put my hands in the air and leaned back. " It would be a shame if I just, fell of this building." His strange scarf shot towards me instantly. " Oop."

I raced through ally's and neighborhoods trying to lose the pro hero, it was almost Kyoyas bedtime and I needed to be home. I stopped and looked around. Nothing, no noise, I lost him. I patted myself on the back and turned another corner, bumping into something hard. Eraserhead. His scarf wrapped around me tightly, taking me into the air. I thrashed around harshly, kicking and yelling. " Let go of me you bastard!"
" It's time you stop being pathetic, there is no in between with hero's and villains, your being immature." " Well fuck you too."
" Oof." I huffed as I was dropped onto the floor of the station carelessly. I sneezed as he talked to an officer and looked around. My eyes widened slightly at the sight a black and purple portal opening next to my left hand.
" This is weirder than 69 thinking ratting people out will get him out of court- hOLY FU-"

" CK-" I finished as I slammed against a cold counter too, crushing a freshly cleaned glass underneath my weight, staining them with my blood. I quickly sat up, ignoring the searing pain of the glass. As soon I as I sat up I noticed a man in front of me, baby blue messy hair sticking out in all directions and a hand covering his face. I looked to my left to see a man made of dark purple smoke with yellow eyes. I inhaled sharply.
" Ok ok my bad, I didn't mean to drop into the circus, sorry to intrude- gOTTA GO-" I tried to run off but the baby blue man grabbed my cape. I looked back in horror to watch it disintegrate. Fuck. I swiped my left hand through the air sending yellow strings around his arms and legs, holding him high in the air.
" Ok I know this was not an accident, who the fuck are you!" I seethed. He laughed, irritating me. I pulled my hand back and pushed it forward, slamming him against a wall hard.
" Answer me you fuck!" He stopped laughing.
" Oh Nova," My eyes widened, he knows my name? I put my free hand up to my face to feel my mask still in place.
" we want to make a deal."
" I'm not interested!"
" Oh but maybe you will be..." I was about to laugh until I heard an almost mocking voice.
" Mama? MAMA!" I lost my focus and the strings retreated into my fingers. I turned around to see the other villain holding Kyoya. My son.
" Don't make it difficult Nova, just hear us out, agree to it, and I won't hurt him." Part of me thought I could beat him, but the sensible part told me there wouldn't be a chance to do it properly. I shakily sighed.
" Fine."

I sat in front of the blue boy, or who I now know as Shigaraki, the shadow man holding Kyoya back and away from me.
" We want you to join us, only temporarily if you decide at the end of the mission to leave. The mission is to send you into UA, have you get inside information, and help us defeat them. Simple." I looked at my son and back at Shigaraki. " My son will go unharmed?" He smirked. " Yes." I shakily sighed.
" Deal."

I held Kyoya with a gentle grip, rubbing his back and he dozed off on my shoulder. I looked down at my boy, slowly put him down on his bed hoping to not wake him up. I paused before pulling the covers over him and climbed under them, hugging him to my chest before covering us, he can only sleep with a story or with me. I'm upset, but I'd do anything for
my little insomniac.
