Set in classical Japan, "Ōkami" combines Japanese mythology and folklore to tell the story of how the land was saved from darkness by the Shinto sun goddess, named Amaterasu, who took the form of a white wolf. It features a sumi-e-inspired cel-shaded visual style and the Celestial Brush, a gesture-system to perform miracles. The game was planned to use more traditional realistic rendering, but this had put a strain on the graphics processing of the PlayStation 2. Clover Studio switched to a cel-shaded style to reduce the processing, which led to the Celestial Brush concept. The gameplay is modeled on "The Legend of Zelda", one of director Hideki Kamiya's favorite series.
