You’re part of the league but your identity hasn’t been exposed to the public yet, like Mr.compress and Twice who always wear masks.

One day, you and the league are having a conversation in an alleyway when Shigaraki sense someone watching you guys from afar

Spinner & Toga: Arguing about something stupid as always

Dabi: I’m just saying, I think vape cloud can make stronger drinks than his current ones.

Kurogiri: Glares at Dabi before rolling his eyes and looking away

Twice: I think Kurogiri’s drinks are fine…Right, boss?

Shigaraki: Doesn’t respond and just scans the area as if searching for something
