Shaman Hunt
The Fudou Myouou, an organization of monks who believe all spirits attached to Shamans are evil spirits, want to send Amidamaru to the other world. When the samurai starts to believe that he is indeed an evil spirit, Yoh has to remind him of their true relationship, and save Mosuke’s spirit and Manta’s body in the process.
