Aizawa: "Why does your personality change like that?" He asks bluntly.
Izuku: " Because of our stupid ass quirk." He scoffs. "I will explain in class, in front of all the little hero hopefuls." He says, walking out of the teachers lounge.
When they get to class and all the students sit down, Izuku walks up to the front.
Oni: "Alright bitches, I am gonna explain why my personality does this." He explains.
Iida: "You shouldn't curse-" He gets cut off.
Oni: "Shut up." He glares. "Alright brats, my quirk creates separate beings in my head and we take turns controlling the body." He explains.
Shinsou: "Then what's with the new personality and do you guys have separate names?" He questions.
Oni: "I don't want to be in control at all but if I don't explain this the others won't. I will introduce myself, hello I am Oni and I live off of anger and spite, fuck with me and you'll be begging for mercy."
He pauses for a second and then Betel takes over.
Betel: "Heyo! I am Betelgeuse! Just call me Betel, I'm psycho happy!" He yells.
Again, another pause.
Red: "Red Dwarf. Call me Red. It is very nice to meet you all properly. I guess I am logic and spite." He explains.
Then Oni comes back.
Oni: "That's it."
