shigaraki was the league of villain leader. you were just a villain like them. Shigaraki didn't seem like much of a fan of you but when you talked to the other league of villain members like dabi and toga, he'd keep an eye on you. You never knew exactly why he did that. You guys were on a mission now and you were fighting a hero, (any hero you want) shigaraki was staying near you while fighting Mirko.
