The game takes place nine months after the events of Ōkami. Despite Amaterasu's battle against the Dark Lord Yami, which would kill all the demons in Nippon, they return. The Konohana Sprite Sakuya, a character from the original Ōkami, summons the Sun Goddess Amaterasu, but instead finds Chibiterasu, who looks like a young version of Amaterasu. Chibiterasu is, in fact, Amaterasu's son. He is a "young form of existence" and not fully grown; he retains several abilities of Amaterasu, including the Celestial Brush, but lacks her power.
The "Celestial Brush", the ability to freeze the screen and draw symbols via the touchscreen with the stylus to bring changes on the game's world, remains central to the game for solving puzzles and fighting enemies. The theme of returning life to the world also returns from Ōkami. A new feature is the ability for Chibiterasu to team up with partners. They can be used to explore the overworld with, as well as battle enemies.
