Quintet Company, Limited was founded in 1989 by the former Nihon Falcom employees Tomoyoshi Miyazaki and Masaya Hashimoto, previously best known as the creators of the Ys series. The company's name signifies the five primary tasks in game creation: programming, planning, graphics, sound, and production.
Quintet was most active in the 1990s and had a strong relationship with Enix (now Square Enix), which published their games mostly on the Super Nintendo platform. Quintet's games frequently portrayed a common theme of two entities, one that brings chaos and destruction and the other that controls creation. Several of their games also feature a dog named Turbo.
In 2002, Quintet appears to have gone inactive. They shut down their internet forum due to an "inability" to say anything to frustrated fans wanting news, and the rest of their website followed suit in 2008. Despite this, both Quintet and members of its staff have appeared in the credits of other games in the interim, such as Atelier Iris and Ar tonelico: Melody of Elemia. This, combined with a general unwillingness by anyone connected to the studio to say anything, leaves Quintet's ultimate fate a mystery.
