Active Software was the Japanese game developer that created the first Bible Black game that was later adapted into an anime by Milky Studio. The sequel game was not produced by the company, as it was defunct at the time. It was instead created by Kururi Active. However, many of the original art and music was retained in the second game.
The company was founded in 1991 in Kyoto, Japan and focused on producing adult computer games. It developed games in various genres; their role-playing game GunBlaze (1994) was re-released on the Sega Saturn (as GunBlaze S) with adult content removed.
Active Software participated in the foundation of Ethics Organization of Computer Software (EOCS) with the aim of imposing age ratings on Japanese software and outlawing games with graphic sexual scenes depicting underage girls. Active's representative director Michiko Sakai served as the board chairman of EOCS until 2000.
On November 1st, 2004, Active Software was disbanded as a stock company. The brand, however, was retained as the developer team continued to work on Seven (2005), their last game. In November 2009 their website went offline, and no further activity was reported.
