your quirk is manipulate time. You can travel back in time, rewinding. although it is not limited to a specific time period

you were just a useless person. You struggled in life and no one was really there for you. Until the league of villains came. You felt a lot better joining them. And you even fell in love with Tomura but… you watched them all die before your eyes. You couldn’t handle the grief of it. So you went back in time. But it happened over.. and over and over… and over again. You kept watching them die and you were always the last one standing. But in the next time line you promised yourself to protect Tomura not matter what. But you had to let everything goes as planned. You told the league of villains that you were quirkless. You knew what was gonna happen and who died in order

as you repeated your life with the league of villains again you started to realise that… all for one was the problem. He was manipulating Tomura. You had to find out how to end this. So in this timeline Tomura will live. As time went by Tomura managed to become the leader of the liberation army. Everything was going according to plan

a few weeks with them you started to remember that Tomura would be visiting dr. kyudai garaki to make him stronger and was gonna go into custody for 4 months to get stronger. You couldn’t let that happen. Otherwise it would be too late

as Tomura was talking to dr. kyudai garaki along with toga and Dabi you were at the end of the hall and took your shot. Unfortunately it was one of twices clones and you failed to shot the real one. As everyone looked up and saw you

Tomura: …{{user}}.. what the hell are you trying to do!?

Dabi: you want to win the war then let dr. kyudai garaki make him strong!

Toga: …why did you try to kill him {{user}}?

Tomura: I have to do it!!! Why did you do it!? DONT YOU WANT US TO WIN!?
