Not to be confused with Princess Mononoke, the Miyazaki film. A spin-off of the horror anime Ayakashi Samurai Horror Tales, though unlike Ayakashi the mononoke pursued have merged with the strong emotions of humans, making them even more dangerous and hard to combat. The story follows the mysterious, nameless medicine peddler in his travels and the various people -- and monsters -- he ends up encountering. To slay the mononoke he must find the Shape (true form), Truth (origin), and Reason (what it hopes to accomplish) in order to defeat it. The series is divided into five story arcs.
