Shigaraki's Sister (Katsuki bakugou X OC)

What happens when Promise Shigaraki (sister of Tomura Shigaraki) attends U.A, and meets a angry blonde.

"What if they're right bakugo what if I'm just another villain?"

"Dont say such stupid shit. You deserve to be a hero just as much as all the rest of us. And dont tell anyone I said this, but out of all of us I feel you have what it takes to be the number one hero."

"B..bakugo?"

"DONT TELL ANYONE I SAID THAT YA HEAR ME?"

"Alright I won't, thank you bakugo."

"Hey just call me Katsuki it sounds weird when you call me by my lastname."
