Samurai Shodown: Haohmaru's Journey to Hell

Samurai Spirits: Haohmaru Jigokuyuki is a 1993 manga written by Shiro Ohno. The story takes place before the events of the first Samurai Shodown game and leads to second series by the same author where it adapts the first two games.

It follows Haohmaru, Charlotte, Nakoruru, Hanzo and Ukyo as they get face to face for the first time, with the resurrected Amakusa. The series is notable for introducing, for the first time, a demon samurai who looks exactly like Haohmaru, a concept that will later be used by SNK for the story of Rasetsumaru in Samurai Shodown V.
