Shaman King

Manta Oyamada, a studious yet shrimpy middle-school student from Tokyo, attempted a shortcut one night through the graveyard to get home after a late night of cram school. While traveling through it, he encounters Yoh Asakura and his "companions": a graveyard filled with ghosts. Yoh reveals himself to be a shaman, a medium between the worlds of the living and the dead. As a shaman, Yoh also demonstrates his ability to possess himself with ghosts to assist him where needed, particularly becoming fond of a former samurai known as Amidamaru. Over the first few chapters, Yoh and Manta become best friends while Yoh uses his shamanic abilities to help them out through various normal tasks.

Yoh soon encounters Tao Ren, a Chinese shaman who uses his own ghost on a quest to destroy humanity as well as prepare for an upcoming Shaman Tournament to be held in Tokyo. Anna Kyoyama, Yoh's fiancée, soon enters the picture and prescribes a brutal training regimen, in order to prepare Yoh for the tournament. The tournament is held once every 500 years and is a battle between competing shaman to choose a winner, who will be known as the Shaman King. This winner will gain the ability to reshape the world as he or she chooses, to make his or her dream come true. Thus begins the plot that will lead Yoh on a journey that will lead him to many friends and adventures.

Through a series of events and also through participation in the Shaman Tournament, Yoh meets and befriends numerous characters and changes their lives through friendship and authentic concern, which seems to be a pervasive theme throughout the series. He also must face his ultimate destiny, connected to one of the most powerful participants in the Shaman Fight who desires to win the tournament and use his prize to annihilate all of humanity for destroying the world, leaving only a world of shamans such as himself.
