The Scroll of Hyakkimaru: Part 1

Daigo Kagemitsu, a warrior in the Age of Civil Wars offers his soon-to-be-born baby`s body to the 48 devils as a sacrifice to fulfill his ambitions. Then the baby is born with 48 parts of his body missing, and is thrown into the river because of its horrifying ugliness. The baby, however, survives. A gifted doctor supplies him with the missing parts, and he grows up with the name "Hyakkimaru." Wherever he goes, demons follow him, but he attacks them with a sharp sword attached to his artificial arms. One day, he meets a thief girl called Dororo who can steal swords of any kind.
