Bible Black New Testament

Several years after the events of Walpurgis Night, the metropolitan area is plagued by a series of unusual murders. The bodies of couples are discovered dead during intercourse. The female victims show no external injuries, while the males are found completely burned and carbonized, with the sole exception of their genitalia. To investigate these bizarre cases, a special detective unit named "Tokken" is formed. Among its members is Imari, who has prior experience from the Walpurgis Night incident. During the investigation, the team uncovers a mysterious phrase, "Spear of Longinus," and a strange cult connected to the crimes.
