Katsuki's New Sibling Life (boku no hero academia x child reader)

Special Chapter: If Reader was at the USJ Attack...

Info: This is not really gonna happen, sorry for those who wanted to, but I have a different plan on how reader gets in UA. Sadly it may be boring, but it is crucial for the plot.

So here is an early chapter to reveal what would happen if reader WAS in the USJ attack.

You looked into his bright red eyes as he stared back at your reptile ones. His chapped lips in a permanent scowl similar to your brother's while yours held a look of curiosity at the man who sat the other end of the seesaw in the deserted playground.

"You look weird."

"You look hideous."

"You have odd lips."

"You have a ridiculous face!" The man yelled at you childishly, winning over and insulting competition, no one knew when it started.

"You are bad at this." You bluntly commented making him gain a tic mark.

"Be a good dog and just follow me." The man barked making your blink indifferently before replying in a straightforward manner.

"Sure.."

[And so...]

"Villains!?" The students gasped as dangerous looking people that exited the weird vortex and among the villain was a child that shocked them even more.

"Hi big brother!" You yelled cheerfully waving at the group, but mainly at Katsuki. Though none noticed.

"I forgot what you said yesterday! Was I supposed to follow a stranger or not follow a stranger?" You asked making the boy internally scream in a life long of frustration.

'I will fucking kill that piece of shiit!!!!' He silently threatened making a shiver run that your spine.

'I guess I wasn't supposed to....' You nervously smiled to yourself as you felt your brother's gaze specifically on your form in a not so friendly manner.

"What's going on?"

"Why is there a kid with them..?"

"Who are they talking to?"

'Everybody shut the fuck up..!'

[Which lead to...]

Y

ou looked at the scene before you scared at the amount of blood using from the hero. Tears were brewing in your eyes, you had no idea what to do.

'I-I.... I wanna go home...' You thought as the man you came with suddenly attacked three of the students, one which you are familiar with, with an intent to kill.

'Its..!' You gasped in surprise as the monster smashed the hero's head to the ground and suddenly Izuku was about to attack the hand man but the one called Nomu stopped it.

You felt a rush of adrenaline flow in your veins as you saw its hand reached over to attack the green head.

"Eh? (Y/N)..!?" Izuku yelped in surprise as you held back the arm of Nomu, almost barely doing so without trembling.

"You are starting to get annoying brat..." Muttered Shigaraki, the villain with hands clinging all over him. "Nomu, deal with them" He said. "But I still need them alive..." Once he finished it resulted into you being tossed to the ground, with the pavement breaking under you.
