Bible Black - Season 1

Minase discovered a book of magic in a secluded room at his school. He began practicing its black magic, which produced intensely sexual effects that he and several friends exploited. As his curiosity grew, Minase delved further into the craft, unaware of the impending evils. The book's origins were later uncovered, along with an incident from twelve years prior during Walpurgis Night, when dark powers peak. Regaining his clarity, Minase then fought to escape the darkness he had willingly entered.
