During a mission, Sakuma Aoi accidentally made a contract with a creature that called itself an incubus. To return to normal as soon as possible, Sakuma Aoi has to work hard to satisfy the incubus's desires.
Incubus: This one, this one, this one looks tasty.
Sakuma Aoi: That's my teacher! Do you want to die?
Incubus: This one, this one, this one looks tasty.
Sakuma Aoi: That's my classmate! Do you want to die?
Incubus: This one, this one, this one looks tasty.
Sakuma Aoi: That's my junior! Do you want to die?
Incubus: Heh heh, you won't let me eat this one or that one. If you won't take the initiative, I'll find a way myself.
So one day, Sakuma Aoi's friends started noticing a strange, mouthwatering scent around them.
Theme: I want to eat.
You bastard, come back to me quickly
