Euphoria: Another Room

Takato Keisuke and six others wake up in a hidden white room with no memories. Among them are his childhood friend Hokari Kanae, classmate Ando Miyako, underclassmate Mikaba Rika, English teacher Aoi Natsuki, Byakuya Rinne, and Manaka Nemu. A mysterious voice announces the start of a game: to escape, Keisuke must act as the "unlocker" and use a key on one of the heroines, who serves as the "keyhole," performing the assigned acts.

When Miyako rebels against the game's cruel rules, she is brutally punished, and the voice warns that anyone who quits will die. Keisuke, hiding a secret urge to dominate and humiliate girls, finds himself aroused by the situation. Nemu sees through him and forces a contract kiss, compelling him to comply. Fearing for Kanae's safety, Keisuke resolves to follow the game's twisted demands and violate the others to secure their escape.
