Manta Oyamada, a shrimpy, studious middle-school student from Tokyo, attempts a shortcut one night through the graveyard to get home after a late night of cram school. While travelling 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 world of the living and the world of the dead. Yoh also demonstrates Shamans' ability to unite with ghosts to achieve a shared goal. 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.
I like this anime. It has a nice plot about shamans competing to become the Shaman King. The animation is fluid especially during the fight scenes. I like that Yoh, the main protagonist, is laid back (almost to the point of being lazy) but he is a really good strategist during their fights. And Hao, the main antagonist is someone you'd love to hate. (Ren may be as equally annoying but he has his amazing moments too..) I remember I used to rush home from school just to watch this anime. I recommend it to those who like adventure anime.
