A boy who refuses to accept his mother is gone travels through impossible lands with a talking rabbit and a giant, each obstacle another way the world tells him to stop looking. The grief never softens, but the companionship does, and that's the whole point. This is mythology as a child's stubborn love story, not a lesson about acceptance.
A grieving boy-god named Susanoo defies his father's warnings and ventures into the world to find his deceased mother, convinced she's waiting somewhere beyond the heavens. Armed with nothing but stubbornness and the companionship of a chatty rabbit and a gentle giant from the Land of Fire, he barrels through impossible challenges and strange lands. His journey leads him to the Izumo Province, where he encounters Princess Kushinada and learns a horrifying truth: her village has been sacrificing maidens to an eight-headed dragon for years. The monster returns regularly, hungrier and more vicious each time, and Kushinada's family is hiding a terrible secret about what happens next. The film blends Japanese mythology with the adventurous spirit of a child's quest, balancing genuine warmth and humor against creeping dread. Susanoo's initial selfishness transforms as he realizes some battles matter more than personal loss. It's a coming-of-age wrapped in folklore, where a small boy discovers that saving others might heal wounds he thought were permanent.
