The students find themselves trapped in the enclosed space of their school with a mysterious creature called “Ruler” and forced into a dark sex game by the will of mysterious forces.
There is a battle royale element in the story, where players use their “game powers” to force each other to cum, for example, turning into a demon, releasing depraved tentacles or applying Futanari torture.
The presenter of the game is a “ruler” who watches beautiful girls as they bring themselves to orgasm in humiliating games using depraved techniques and body modifications.
