Milky Studio has since adapted the game into several adult anime adaptations. The first adaptation, simply titled "Bible Black", consisted of six episodes animating numerous scenes from the video game. The following year, a two-episode OVA titled "Bible Black: Origins" was released, which served as a prequel to the events of "Bible Black". In April 2004, Milky Studio produced a sequel series titled "Bible Black: New Testament", which follows the exploits of the original characters ten years after "Bible Black" takes place. The latest OVA adaption, "Bible Black Only", consists of gaiden stories explaining what happened to various characters during the plot of "Bible Black".
