Amaterasu (「天照」?; lit. "heaven's illumination") is the main protagonist of Ōkami. She is also known by villagers of Kamiki Village in her past life as the dreaded Shiranui. She is nicknamed as Ammako by Ishaku and later Issun in the original Japanese version of Ōkami, or Ammy in the localized game. Amaterasu is the Sun Goddess to all of Nippon and mother to Chibiterasu.
Amaterasu is known for being quiet, mature, kind, and gentle always aiding those in need, but also unafraid to show her opinion. For example, when Mr. Orange talks to her after drinking his sake, Amaterasu looks away and breathes, implying he has bad breath. She is also very intelligent, as when she encounters Rao at Queen Himiko's throne room, she figures out she is the demon lord Ninetails. Amaterasu is apparently offended quite easily, shown when Mr. Orange says she doesn't look very smart, as well as Issun saying that "Ammy gets kinda sensitive about her flaws!". According to Mrs. Orange, Amaterasu is quite fond of her cherry cakes. She also has a low attention span, which results in her falling asleep if someone explains something for too long or if she already knows what is being explained.
