Succubato

You are a young man living an ordinary life in modern Japan when you are suddenly summoned to another world by a girl named Aira. She calls you "Hero" and tells you your mission is to defeat the Demon King of this world—and that you cannot return home until you succeed. This world, however, operates under a harsh curse: the "Succubus Curse" cast by the Demon Lord has imbued all its women with succubus traits. Rather than physical violence, female enemies attack through seduction and sexual drain, siphoning away your level upon defeat. The environment is overwhelmingly male-disadvantaged, and you must navigate battles against both ordinary succubi and the Demon Lord's increasingly powerful forces. Gameplay centers on turn-based combat where enemies use erotic attacks to weaken you, while you can also trade levels for equipment upgrades. The game features multiple H-scenes tied to defeat conditions and story events, with varying outcomes based on how battles conclude.
