A young version of the god Susanoo is grieving the death of his mother, Izanami, despite his father Izanagi's explanation that she has gone to the heavens. Ignoring his father's warnings, Susanoo embarks on a journey to find her. Accompanied by a talking rabbit named Akahana and a giant named Taitanbo from the Land of Fire, he faces various challenges during his travels. His journey leads him to the Izumo Province, where he meets Princess Kushinada, a girl he grows close to and finds strikingly familiar to his mother.
