is a Japanese shōjo manga series by Natsumi Itsuki. It won the 21st Kodansha Manga Award for shōjo.[1] It was adapted in 1997 into an OVA series.
Kuraki Fuzuchi is a handsome and quiet young man who has immense psychic powers and sword skills. He meets Takeo Nanachi, a college student with similar powers.
The story opens with Nanachi traveling to a small shrine in the mountains to purify his deceased grandfather's sword in a festival that only occurs every 49 years. 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 ghosts, spirits, demons, and other characters with supernatural powers while the author provides a parallel running story depicting their previous life.
