KID

KID was founded in 1988, with capital of 160 million yen and 31 employees. In the early 1990s, it served primarily as a contract developer. Notable titles from this era include Burai Fighter, Low G Man, G.I. Joe, Isolated Warrior and Recca. In 1997, it began porting PC games to games consoles. In 1999, it released an original title called Memories Off on PlayStation, which later became its first well-known series. Pepsiman was also released in 1999, to little initial success, but the title eventually became seen as a cult classic. In 2000, it released the original title Never 7: The End of Infinity, the first in the Infinity series. KID created the underground PlayStation game Board Game Top Shop. In 2005, KID became a sponsor of the Japanese drama series Densha Otoko.

The company declared bankruptcy in 2006. However, in February 2007 it was announced that KID's intellectual properties had been acquired by the CyberFront Corporation. CyberFront would continue all unfinished projects until its own closure in December 2013.

Kaga Create then bought CyberFront Corporation and owned the rights to KID's works. After Kaga Create closed down, 5pb. bought Cyberfront's assets which also included all of KID's works.
