"Kill the annoying brat."
Katsu P.O.V.
Wait, she used to live with them... I look down at the villains, seeing him. The guy that helped that girl kill my older brother. Dabi.
*flash back*
"S-shut up Kiyoko!" I say, aggravated. My brother laughs at me. "Oh come on! I know you like Shoto!" Kiyoko says, laughing at me. I blush as we walk down an alleyway. We continued to walk straight. Out of nowhere, a girl with a cap on, covering her hair, about my age, jumped off a house roof. "Dabi, we've got a hero in training!~" The girl coo's, referring to my brother, who is a first year at UA. A guy with some kind of patch work on his skin, jumped off a different house roof, joining the girl. "Good job at spotting, peppermint. Guess you're not so useless after all." the guy says. The girl looks at Kiyoko with her grey and blue eyes. "STAY BACK, OK, KATSU!" My brother yells, pushing me back. The girl looks at me, surprised. "Leave the girl, Dabi..." the girl mutters. The boy, Dabi looks back at her. "What?" he asks, very surprised. "LEAVE THE GIRL!!" she yelled. Dabi grunts and runs towards us. Kiyoko runs at him, activating his quirk, paralyzation. But the girl was ready. She put a wall of ice between them, making Kiyoko run face first into it. He starts punching it, but it wouldn't break. "Kiyoko! Leave them, please! Let's go home." I cry. But it was too late. He was dead.
*flash back ends*
"Katsu?" I look down at Marchmi, he grey and blue eyes looking at me in confusion. "You..." I say, backing away. I backed up into something, I turned around and gasped. The mist guy, Kurogiri, was right behind me. "Stay back students!" 13 says, pulling me back. "I have a very dangerous put useful quirk, blackhole. I can suck anything inside it, especially you, villain. Now be read- NO I SAID STAY BACK!" Kirishima and Bakugou went running up to Kurogiri. "Kiri! NO!" someone yelled, but Kirishima and Bakugou just passed through him. "You fools! I am a warp gate, you can't kill me!" He then surrounds us with his mist, sending us places. When everything cleared up, I saw Yaoyozoru, Jiro, and Kaminari. A huge group of thugs surrounded us. Uh Oh this can't be good.
Ok i'm going to explain Katsu's past.
At the age of 7, Katsu was sexually assaulted by her step-father, causing him to go to prison. She lived with her brother, until his 16th birthday, where Dabi and Marchmi attacked him and killed him in cold blood, but leaving Katsu alive. It has been only one year after what her step-father did to her, so it surprised everyone that she didn't lose her mind, but kept fighting her past, trying to forget it.
