Shiro Ohno

A girl is sent to another dimension, where she finds OZN, a warrior with a unknown past.

The story begins with Hanzo Hattori checking on his comatose son, Shinzo. Although he knows that his son's body is alive, Hanzo laments his powerlessness in saving his son's soul. While he prays for his son's revival, Shinzo's soul flickers into his body. He tells his father that Amakusa's soul is still alive in the Makai (demon world), begging his father to stop the villain. Moments later, his soul is struck back into the Makai by Amakusa, once again leaving Shinzo's body lifeless. Enraged and in grief, he leaves to try and get his son's soul back.

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.
