Euphoria

Keisuke Takatou awakens in a featureless white room, with no knowledge of how or when he arrived. As he explores, he discovers six familiar girls gathered around a large monitor: his childhood friend Kanae Hokari, class president Miyakou Ando, his English teacher Natsuki Aoi, his junior Rika Makiba, and classmates Rinne Byakuya and Nemu Manaka. Miyakou refuses to accept the situation and denies any involvement. Suddenly, the room plunges into darkness. When the lights return, Miyakou is strapped to an electric chair. A mysterious voice declares, "Withdrawal from the game will result in death," and she is electrocuted to death. With no other choice, the terrified captives agree to participate, and the sadistic game begins, designed to awaken their carnal desires through pain and pleasure.
