The story revolves around a boy named Raizou Katana. He was living in a village where the villagers despised him for having a horn on his head. When he meets Kagari and Kisarabi (a group of kunoichi), he discovers that he is the illegitimate heir to the fallen Katana clan and must revive his household to its original state. They planned to revive it by marrying a princess of another household and borrowing their power. Throughout the series, Raizo eventually wins over the princess but runs away due to a misunderstanding. A group called Kabuki Seigan also attempt to control other households but fail when Raizou intervenes, which causes more anger towards Raizo.
