Black Package was founded in 1995 by several ex-Discovery staff, initially as a brand of Disc Co., Ltd.. Later that year, Geo Corporation acquired Discovery and Black Package from Disc Co., Ltd.. Then, in 1996, Black Package became a brand of the newly formed Edge Co., Ltd..

The independent Black Package was mostly staffed by those who worked on Miwaku no Chousho, and on games from Frontier and Discovery games such as Marine Rouge. The staff on Kara no Naka no Kotori did not stay on with Black Package and instead started their own company, Studio B-Room.
