A visit from a woman affiliated with a certain religious group—an incredibly cute girl who appears well-groomed but exudes a slightly eerie aura. If she keeps coming to your house every week, you'd definitely want to seduce her. How intimate can things get under the pretense of inviting you to join her faith? Pretending to seek advice, she clings to believers for comfort. Each time, released from her usual ascetic lifestyle, she becomes increasingly uninhibited and shamelessly lustful. A mischievous game of showing off masturbation draws her even deeper. Tempted by the very religion she trusted, after experiencing sex, her story takes an unexpected turn—leading to an unbelievable event waiting just ahead.
