"Ultra C" is a collection of live footage from the second day of Tokyo Jihen's national release tour for their fourth studio album, "Sports", held in 2010 at the Tokyo International Forum Hall. As a feature of this tour, the venues covered prefectures that are closely related to all the members (hometowns, etc.), and special menus were prepared at the relevant places (Chiba, Fukuoka, Osaka, Shimane, and Okayama.)
