Manta Oyamada

An intelligent but worrisome teen who always carries a "dictionary/encyclopedia/compendium of all human knowledge", and has a sixth sense, meaning he can see supernatural beings, even though he is not a Shaman. He is very expressive and a bit panicky. His rather abnormal height has gotten him into trouble numerous times, once having been mistaken for one of the shy nature spirits, and being cut open and used as a hostage of sorts during Yoh Asakura's match with Faust VIII. In the anime, during the final battle with Hao, he actually becomes a Shaman and is able to merge with a spirit.
