Shin Bible Black (also known as New Bible Black or Bible Black: New Testament) is the third installment in the Bible Black hentai series, set several years after the original events. The story follows former Witchcraft Club members who have grown into adult roles—teachers, a Buddhist nun, and a psychic police investigator—as they confront a series of occult-related murders occurring during sexual encounters, alongside supernatural possession and intense black magic conflicts centered on the mystical Lance of Longinus and the "Scarlet Woman."
