Shaman King

Manta Oyamada was taking a late night walk, when he ran into his classmate You Asakura. You invited him to come stargazing, but it turns out they were going to a cemetery, with the friends being ghosts! Manta was surprised, but You was happy he could see them, since he had a rare sixth sense. Later, Manta was beaten up by a gang, and You wanted to avenge him. They used the help of Amidamaru, a samurai ghost who's tomb was broken by the leader of the gang. Manta started to learn more about the world of spirits, like the Shaman Fight. You wanted to enter this tournament and become the Shaman King, the one to control the Great Spirit and shape the world.
