Shaman King

The plot of Shaman King revolves around Yoh Asakura, a shaman, a medium between the worlds of the living and the dead. Yoh seeks to become Shaman King, one able to channel the power of the Great Spirit to reshape the world as they wish, by winning the Shaman Fight, a tournament overseen by the Patch Tribe that occurs once every 500 years. Anna Kyoyama, Yoh's fiancée, soon enters the scene and prescribes a brutal training regimen to prepare him for the tournament. Thus begins the plot that will lead Yoh on a journey that will lead him to befriend Manta Oyamada and encounter other shamans: "Wooden Sword" Ryu, Tao Ren, Horohoro and Faust VIII.

Yoh's group travels to America to pass the final trial for the right to participate in the Shaman Fight, joined by Lyserg Diethel while encountering a group of shamans led by Yoh's estranged twin brother Hao Asakura, the reincarnation of a powerful shaman who wishes to eradicate all humans and create a world for shamans. The group also encounter the X-Laws, a group dedicated with killing Hao, with Lyserg joining them. Yoh's team is joined by Joco McDonnell (known as Chocolove McDonnell), as they engage in a series of three-man matches.

Before creating Shaman King, Takei, an assistant of Nobuhiro Watsuki's Rurouni Kenshin, exchanged ideas about the series with the other assistants which included the creator of One Piece, Eiichiro Oda. As a colleague of Watsuki, he worked primarily as a manga assistant, only focusing on his own projects during his days off. He was influenced by street art from hip-hop and rap culture, which is apparent in his manga artwork. For drawing, he used calligraphy inks and pen nibs. When illustrating, he used Copic brand color markers.

He chose shamanism as the principal topic of the series because he wanted to choose a subject that had never been approached in manga before. He said he incorporated his own personality and beliefs in Shaman King. He has an interest in the topic, and "choosing shamanism as the subject of this story seemed like a natural extension of that." For the title, he said he used "shaman", an English word, due to the fact that "the nuance is really great" and because he could not find a Japanese word with the accurate meaning of the word "shaman". Another reason to have shamanism as the main subject was because he could explore elements from different cultures and their relationship with the dead and the spirits.
