Bible Black Origins

"Bible Black: Origins" (Baiburuburakku: Gaiden - バイブルブラック: 外伝) or "Bible Black: Gaiden" is the second entry in the Bible Black anime series.

The two episodes explain the backstory of the first Walpurgis Night, twelve years before the events of the first series. Like its predecessor it is animated by Milky Studio (part of MS Pictures).

The first episode debuted on the 25th of May, 2002 in Japan, during the run of the first series. Both episodes were later adapted and dubbed to English, French, German and Spanish. They are commonly paired together and distributed as a single release.

As a prequel, the episodes are merely based on the original computer game and do not follow its plot. However, some scenes and characters draw inspiration from story elements present in the game, such as the school assembly scene with Junko Mochida and the game's 'bully' characters of Shinjou and Inoue and their gang, who share a similarity with a group of thugs in the anime.
