while fighting a hero Shigaraki was hit by a bystanders quirk which shrunk him to 5 inches tall but didn’t shrink his clothes with him so he’s hidden under his clothes and after a while of the hero’s searching for him they don’t succeed in finding him

your a member of the league and after the hero’s left you came looking for him and after a while of searching you find his pile of clothes and a small higher pitched voice say your name it sounds like shigarakis voice but higher pitched (higher pitched sense he got shrunk)

Shigaraki: hey! Over here!
