Shaman King (Japanese: シャーマンキング Hepburn: Shāman Kingu) is a Japanese manga series written and illustrated by Hiroyuki Takei. This manga follows the adventures of Yoh Asakura as he attempts to hone his shaman skills to become the Shaman King by winning the Shaman Fight. Takei chose shamanism as the main theme of the series because he wanted a topic that had never been attempted before in manga.
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 the Shaman King, the one who is able to contact the Great Spirit, and will gain the ability to reshape the world in any way they wish, and for this purpose he must to win the Shaman Fight, a battle held once every 500 years between competing shamans. 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 Ryu, Tao Ren, Horohoro, Faust VIII, Lyserg Diethel, and Joco McDonnell (known as Chocolove McDonnell).
During the Shaman Fight, Yoh encounters Hao Asakura, a strong shaman who wishes to eradicate humans and create a world for shamans. At the end of the shaman battles, the remaining teams consist of Yoh and his friends, the X-Laws and Hao's team. The remaining teams choose to forfeit the tournament, crowning Hao with the title of Shaman King. As Hao is led away, Yoh and his allies decide to attack Hao while he is merging with the Great Spirit, which is in a coma. To conquer Hao, Yoh and his friends must defeat The Patch Tribe members who are obligated to serve under the new Shaman King.
After Yoh and his friends overcome the ten Patch Tribe members, Hao is awakened as the new Shaman King. He defeats Yoh and all his friends and absorbs their souls. Inside the Great Spirit, Yoh, Ren, Horohoro, Lyserg, and Chocolove battle against Hao using the five legendary spirits: the Spirit of Earth, the Spirit of Thunder, the Spirit of Rain, the Spirit of Fire, and the Spirit of Wind. When former associates of Yoh and his friends begin appearing in the Great Spirit, it is revealed that the Great Spirit granted Hao's wish for someone to bring back his mother's spirit. With Anna's help, Hao's mother is brought to the Great Spirit. Hao's mother tells him that, in order to be saved, he must forgive the humans for murdering her. Hao decides to postpone his plan to eradicate humans and to observe how Yoh and his friends will change the world.
Seven years later, Hana Asakura waits at a station for the five legendary warriors and his parents, Yoh and Anna.
