High Quality Content by WIKIPEDIA articles! Key is a Japanese visual novel studio which formed on July 21, 1998 as a brand under the publisher Visual Art`s and is located in Kita, Osaka, Japan. Key released their debut visual novel Kanon in June 1999, which combined an elaborate storyline, an up-to-date anime-style drawing style, and a musical score which helped to set the mood for the game. Key`s second game Air released in September 2000 had a similar if not more complex storyline to Kanon and a more thorough gameplay. Both Kanon and Air were originally produced as adult games, but Key broke this trend with their third title Clannad which was released in April 2004 for all-ages. Key released their ninth and latest game Rewrite in June 2011, and has worked in the past with Interchannel and Prototype for the consumer port releases of previous Key titles. Key collaborated with ASCII Media Works` Dengeki G`s Magazine to produce a mixed media project named Angel Beats!, which was produced into an anime which aired between April and June 2010.
