Oyamada, Manta

小山田まん太

Manta Oyamada is a smart but anxious teenager who always carries a "dictionary/encyclopedia/compendium of all human knowledge." He possesses a sixth sense, allowing him to see supernatural beings despite not being a Shaman. He is very expressive and somewhat panicky. His unusual height has caused him trouble on several occasions; he was once mistaken for a shy nature spirit and was cut open and held hostage during You Asakura's match against Faust VIII.

Spoiler

Manta Oyamada narrates the story in the manga and anime, helping readers and viewers understand the plot more efficiently. He is referred to as "Morty" (short for Mortimer) in the English anime. (Hiroyuki Takei mentioned in an interview published in the March 2004 English language issue of Shounen Jump that Manta's character was modeled after Japanese pop singer T.M.Revolution.)
