The Scarlet Devil Mansion and the Book of Succubi

A short fantasy RPG in which three heroines—Flan, Patchouli, and Sakuya—become trapped inside the "Book of Succubi" and must fight their way out against lustful supernatural enemies. During combat, enemies use restraints and erotic status effects to incapacitate the party; if restraints are not broken, the characters will be sexually assaulted and experience orgasm, rendering them unable to fight. The game features turn-based battles with dynamic erotic artwork that changes based on combat state and status effects. Gameplay focuses on surviving the onslaught of monster encounters while managing the party's condition, with an estimated playtime of 1.5–2 hours.
