Past

Shaman King:Master of Spirits
Magister's ancestors were shamans who were defeated by the Hao, so he holds a grudge against all shamans, Yoh in particular. Magister wants the Tome of The Shaman to bring Mephias, a former Shaman King, back to life. He tries to steal The Tome from Anna Kyoyama while Yoh and the gang are resting from the Shaman King tournament, however the pages were scattered, so Yoh and his friends went searching for the pages. Magister then took control of Ryu's mind and made him attack Yoh, who fought and defeated Ryu, Ryu then told Yoh that the last thing he remembered was Magister.

Magister then trapped Usui Pirika in a purple crystal and told Horohoro to destroy Yoh or else he will never see his sister again and well send her in other world. however Horohoro was tempted when Yoh said to take it a little easy, however Horohoro only tells Yoh to shut up. Horohoro then fights Yoh but then he loses. Pirika is then freed from the crystal by Anna and Manta comes and take her back to the Funbari Inn. Yoh then fights Faust and Chocolove, who were also brainwashed by Magister. Finally Yoh finds Magister and defeats him in a one on one fight. However, Magister succeeds in reviving the former Shaman King Mephias who proceeds to cut him down in cold blood. Yoh later laments Magister's fate and swears becomes more determined to stop Hao.
