Big Brother

 Shigaraki and Reader

Reader is a teenager, just infantilized by AFO and Shiggy because they missed her younger days due to not knowing about her existence.

I have no brain, sorry ziakitty for forgetting your request

Shigaraki hadn't thought that having a sibling would be as nice as it was, granted it was a teenager that was the daughter of his Sensei, he wanted to do the things he never got to do with anyone as a kid. He was going to be the best big brother! 

'......It wasn't as great as I thought it would be...' he thought, watching his baby sister struggle to escape her pretty pastel room, well cube, as there were no doors or windows. 

"Kurogiri. Warp me." He said, eyes still firmly planted on the image of his little sister.

"Yes, master Shigaraki." Kurogiri says, making a portal to the pastel room. He warps right behind (y/n) as she tries to knock down the wall again. 

"(y/n), you are going to hurt yourself like that." He says in a quiet tone. 

"Shut up! I will get out of here and get all of you villains arrested!"   (y/n) screamed in frustration. It made him annoyed, his little sister was being a brat.

"How would they feel? Knowing that you're a villains daughter? Would your 'friends' accept you?" He snaps, gasping and apologizing immediately

"..s-shut up...they will still care about me..." (y/n) starts sniffling, it made Shigaraki freeze. 

'Oh. Oh no. I made my baby sister cry. I am such a horrible big brother.' He holds (y/n) tight against him, muttering to her that it is okay and he didn't mean it. 

As (y/n) started to calm down and fall asleep, she whispers

"Love you big brother"
