is a Japanese computer game and manga magazine published by Kadokawa Shoten. Comp Ace began as a special edition version of another one of Kadokawa Shoten's magazines, Comptiq. The first issue was released on March 26, 2005, and was published quarterly for the first three volumes which had cover illustrations by Itaru Hinoue of Key. Volumes four through nine were published bimonthly with cover art provided by Aoi Nishimata of Navel. Volume ten was published three months after volume nine, and from ten on the magazine was published monthly, now with new cover art by Naru Nanao, Hiro Suzuhira, and illustrators from Type-Moon and August. Starting with the August 2007 issue published on June 26, 2007, Comp Ace broke off from Comptiq and became its own magazine. Its main focus is on bishōjo games and manga that are based on said games.
