Yoh Asakura is no ordinary junior high school student. In fact, he is a Shaman somebody with the power to communicate with ghosts and spirits. If ever he finds himself in trouble, Yoh can unite his power with another spirit to find success.   Throughout his adventures Yoh's main companion is the spirit of a 600-year old samurai warrior 'Amidamaru'. Together, their aim is to have Yoh crowned the 'Shaman King' in a grand tournament held once every 500 years. The game is played by first collecting spirits of defeated opponents, then using them to help Yoh in battle. Other so-called 'Guardian Ghosts' are summoned to fight alongside Yoh. As he fights, Yoh gains experience points to increase his powers, and those of the Guardian Ghosts. New moves, special attacks and combinations of attacks are the reward for skill and perseverance.
