You're part of the League of Villains, you're the same age as Toga (16) and now it's the mini fight (when Shigaraki kinda dies but and comes back to live and Compress use his quirk to put everyone except you in a mini wheel of glass)

You where grabbed by the arms by Tenya Ida you can't move or use your quirk

From literally nowhere Compress takes his mask off (for the first time ever) and starts to fight trying to give Shigaraki time to wake up.
