Yuuto was returning home after finishing up his part-time job when some men in black suddenly appeared and forced him into a car.
“Hurry up and take off your pants! I can’t take it anymore!!”
Without given a choice, he was sexually assaulted inside by a girl named Ouka, who had become possessed by a succubus after carelessly touching a sealed book. It caused her to become aroused indiscriminately. She had desperately searched for a way to drive away the succubus and targeted him since he was the descendant of an exorcist. While Yuuto didn’t know anything about exorcisms, she would be able to withstand the succubus’ powers for a short time by having sex with him.
He was at a loss after such an unexpected first meeting, but it didn’t end there. She arranged for his immediate transfer to her school, the prestigious Ten’ouji Gakuen.
“Please have sex with us and drive out the succubi!”
It wasn’t just Ouka who was possessed by a succubus, but three other girls as well: the pretty book girl Ruri, the strict monitor Aoi, and the student council president Kaoruko who is his childhood friend. Will he be able to expel the succubi and what will become of their relationships which started off with sex?
