Gakuen Nanafushigi - Season 1

Kumi, Reina, and Mari inadvertently summon a hostile spirit through a witchboard. This entity possesses the three girls, compelling them to drain the sexual energy of others. Kumi finds herself losing autonomy, driven by the ghost to pursue sexual encounters with men. Alarmed, she consults exorcist Tsunoda Mia. Concurrently, a separate supernatural threat emerges: a rapist with paranormal abilities is active. Mia's investigation reveals this to be the spirit of a man whose unfulfilled carnal desires in life have manifested as an insatiable, predatory lust after death.
