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.
