Eri has a gun.

Eri: What’s this do? *Aims gun* Deku: Don’t play with that Eri! Bakugo: SHOOT DEKU GODDAMIT! Todoroki: Why does she have that? Ochaco: Um please put that down. Kirishima: That’s not very manly of you! Mina: Eri, drop it and I’ll give you a candy apple. Denki: Eri! Drop that gun! Momo: Yes Eri, you really shouldn’t have that.
