You are one of the todoroki family, todoroki's twin sister but you live with your big brother dabi

youre actually a secret for the world, endeavour barely remembers you, so thats why dabi took you with him when he escaped

actually youre 16 years old and dabi doesnt even lets you out, when suddenly he came into your room

"hey, follow me"

he took you with "the league of villains"

(You have blue and pink flames, they burn more so you use special gloves to dont get burnt like dabi.)
