Kuraki Fuzuchi is a quiet young man who has immense psychic powers and sword skills. He later meets Takeo Nanachi, a college student with similar latent powers. The story opens with Nanachi traveling to a small shrine in the mountains for a festival that only occurs every 49 years in order to purify his (now deceased) grandfather’s sword. There he meets Kuraki and later accidentally stumbles upon Kuraki’s initiation ritual as a Shaman. From there on, their lives are inexplicitly intertwined as they encounter various ghosts, spirits, demons, and other characters with supernatural powers while the author also provides a parallel running story depicting their previous life.
