Amidst this extraordinary event, Manta Oyamada, a regular middle schooler running late one evening, encounters a young shaman named You Asakura in a cemetery. Initially startled by You's spectral companions, Manta soon forms an unlikely bond with the aspiring shaman and his ghostly ally, the ancient samurai Amidamaru. Together, they embark on a journey to fulfill You's ambition of claiming the revered title of Shaman King through formidable challenges and powerful alliances.
