Anime Sex - Bible Black New Testament - 6

Several years have gone since the Walpugis Night incident, and the metropolitan area has seen a number of strange serial murder cases. Couples' bodies are discovered slain during sexual encounters. The women were unharmed on the outside, but the guys were fully charred and carbonized, with the exception of their genitals. To investigate these strange occurrences, a special investigative team known as "Tokken" is dispatched. Imari, who had witnessed the events of Walpugis Night, is among the Tokken members. They discovered a mystery term, "Spear of Longinus," and a bizarre cult group linked to the happenings while studying the incident.
