Amaterasu (天照; nicknamed Ammy by Issun) is the main protagonist of Ōkami. She is also known by villagers of Kamiki in her past life as the wolf Shiranui. Amaterasu is the Sun Goddess to all of Nippon and mother to Chibiterasu. 100 years ago, the wolf Shiranui fought with legendary warrior Nagi against the evil Orochi (not to be confused with Orochi), who demanded one female sacrifice every year. The wolf and warrior fought Orochi, and eventually Orochi was defeated. Unfortunately, Shiranui became poisoned during the fight and died. The villagers then made a statue in the wolf's honor. 100 years later, when darkness envelopes the world, the wood spirit Sakuya revives Amaterasu in this statue to fight the reawakened Orochi.
In M.U.G.E.N, Amaterasu has been made many times by MGSSJ2.
