Nippon (Japan) and it is based on Japanese folklore, beginning one hundred years in the past. A narrator describes how the white wolf Shiranui and swordsman Nagi fought and sealed the eight-headed demon Orochi at the cave, to save Kamiki Village and Nagi's beloved maiden Nami. Nagi's descendant and self-proclaimed greatest warrior, Susano, refuses to believe in Nagi's legend and frees Orochi, who escapes and curses the lands, sapping the life from Nippon. Sakuya, the wood sprite and guardian of Kamiki Village, summons the long-dormant Amaterasu in the form of a reincarnated Shiranui, and asks her to remove the curse that covers the land. Accompanied by the artist Issun (an inch-high creature known as a Poncle), Amaterasu begins to restore the lands to normal state.
