[ Hentai Sex ] Bible Black New Testament - 4

Several years have passed after the Walpugis Night incident, and several strange serial murder cases have occurred in the metropolitan area. Couples' bodies are discovered slain during sexual encounters. The women had no visible damage, but the guys were fully charred and carbonized save for one part... their genitals. To investigate these unusual instances, a special investigative team known as "Tokken" is dispatched. Imari, who witnessed the horrors of Walpugis Night, is one of the members of Tokken. While examining the occurrence, they discovered a mystery phrase, "Spear of Longinus," as well as a bizarre cult group connected to the episodes.
