Wanpaku Ouji no Orochi Taiji - Movie

This anime film tells the story of the god Susano'o (as a cute boy), whose mother Izanami has died. He is deeply hurt by the loss of his mother but his father Izanagi tells him that his mother is now in heaven. Despite Izanagi's warnings, Susano'o eventually sets off to find her. Along with his companions, Akahana (a little talking rabbit) and Titan Bō (a strong but friendly giant from the Land of Fire), Susano'o overcomes all obstacles in his long voyage. He eventually comes to the Izumo Province, where he meets Princess Kushinada, a little girl whom he becomes friends with (he also thinks that she is so beautiful that she looks like his mother). Kushinada's family tells Susano'o that their other seven daughters were sacrificed to the fearsome eight-headed serpent, the Yamata no Orochi. Susano'o is so infatuated with Kushinada that he decides to help her family protect her and slay the Orochi once and for all and he, Akahana and Bō prepare for the showdown.
