The company was founded in May 1990 when the game music division of the record company Polystar spun off and became an independent company. Upon becoming independent, it entered the video game market and in the late 1990s, gained fame with the "Roommate" series. The company also released a number of video game soundtracks for companies like Sega and Sony.[2] After the release of the album Takemoto Izumi Uta Kore in 2009, it became dormant until it was fully dissolved and liquidated on February 7, 2019.[3]

Yukio Kakehi was the company's president for the entirety of its existence.
