Hyakkimaru (百鬼丸, Hyakkimaru) is the main protagonist of the Dororo series. He is a ronin searching for parts of his body that were stolen from him by demons and slaying said demons. The demons originally took his body parts as part of a pact with his father and archenemy. After learning the entire truth from his mother, Lady Nui, he vows to kill his own father in retribution, even his somewhat warmhearted fifteen-year-old younger brother, and regain all of his missing body parts.
