A down-and-out samurai who can't even hold a sword enters a strange world of magic searching for honor and redemption. In early 19th-century Japan, a down-and-out samurai named Ryudo Konosuke struggles through his hardscrabble life. His dear departed mother's last hope was for him to live his life as a splendid warrior, but a cruel curse repels and distorts any metal that gets near him.

Struck by a curse that affects his memory, he can't remember who Tsuki was. Then he meets Aya, a young medium whose powers may help Konosuke recover his memory and aid him in his search for Tsuki. His inquiries lead him to the Bureau of Onmyo, who are more than just glorified fortune tellers...
