Freelance photographer Kouhei Midou is completely oblivious to spirits and the supernatural. Despite that, he unwillingly manages to capture ghosts on camera nearly every time he takes a photo. His friend Hiromi is the editor of an occult magazine, and decides to make use of Kouhei's talents by having him photograph the supposedly-haunted Schwarz Quelle castle in Germany. While there, Kouhei discovers a young girl named Hazuki who claims to be trapped in the castle, and decides to help her escape. But is there more to Hazuki than meets the eye?
