Everything is not as it seems in the school grounds, rumors run amok about students practicing black magic, an a secret room down the basement is said to hold the secrets to an unholy ceremony celebrated 12 years ago that unleashed unknown horrors. As the young student Minase, you'll find out that there is plenty of truth behind the rumors as he uncovers an ancient book filled with spells that grants him incredible powers. As the story unfolds you'll begin to learn the secrets of black magic, and use the spells for your own personal gain and pleasure. But there are nasty consequences to the miss-use of magic, and many seek to get their hands on the book, including the survivors of the fabled ceremony that took place years ago.

Bible Black is a hentai adventure game in which you interact with the game world and characters from a first-person perspective and more or less follow the plot along as a digital novel until you get to one of the several branching points and get to make a decision between a few options that carry the game in different directions. Graphics are 2D, using hand-drawn illustrations for characters and backgrounds.

The game features 12 different endings, CG and event galleries, the original Japanese soundtrack with English subtitles and other niceties. As with other hentai games, Bible Black includes graphic uncensored depictions of sexual situations.
