The power to save or destroy the world (Katsuki x Reader)

Y/n's POV

"Mommy! Mommy!" The broken girlish voice echoed in my head, the scene playing out on repeat, the blood splatters as vibrant as the sun.

I couldn't stop it and yet I wanted too.

I felt darkness like no other crowding into my head, making me feel sick and weak as I sobbed continuously.

Kofuku's POV

"Mommy!" She wasn't waking up, her normal h/c was streaked with grey strands, her e/c were a glowing white as she she screamed out.

Her s/c had lines racing all over her, dark purple and inky and blinding white swirling around all over and pulsing with energy.

She was in the final war, between the light and dark of her own mind, the thing that monster of a man was trying to push my mind into, it's what he described to the blonde psycho and purple man.

"Mommy...please..." I whimpered out, my voice hoarse and cracking slightly as I looked at the broken form of my mother.

Katsuki's POV

"THAT ALL YOU GOT YOU PURPLE EYED SNAKE??" I cackled even as I wiped the blood from my busted lip, I winced as I looked to my damaged left arm, black veins racing up it.

"Don't be foolish you mindless impulsive brat! I've got you beat by triple amount your power, nothing can stop me at this point!" He laughed manically, eyes crazed as he gives a poisonous grin.

I grit my teeth and spare a glance at y/n and grimace harder, her body bruising from nothing as she writhed around in pain.

"You've got this shorty, don't leave me now." I growl out and jump back into the fight, meeting his fist with mine, the force knocking me back.

Y/n's POV

Just as the scene of my mother's death was about to replay for the hundredth time everything freezes and a searing white light appears, I bring my eyes to the figure that seems to appear, blurry from the watering cause by the brightness.

"It's okay my love, forgive yourself please. It's time to let go and breathe." I feel the whisper of soft lips across my forehead before I shoot awake, feeling hot. I feel rather than see everyone around me, fighting and defending the city against multiple evils.

I target the strongest one, one made of pure black mist and release the pure heated energy building within my body, I feel it enter the body, burning and searing everything inside it to complete ash in a instant.

But it wasn't enough, the energy was too much and I screamed in agony. Not understanding anything as I lost control.

"Mom I need you. Please."
