Samurai Shodown

Based on the popular fighting game series by SNK, known in the West as Samurai Shodown.

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.

Haohmaru, Nakoruru, Wan-fu, Galford, Tam Tam, and Charlotte. Together, these six fighters form the Holy Warriors: preordained soldiers who keep the seal over the dark god Ambrosia from being broken. They were defeated by the evil Amakusa but their souls reincarnate a century later. At this time, Ambrosia begins to quake the globe and his arrival is of eminent concern. Each one remembers their mission and effectively join together once more to honor their pledge. All except Haohmaru, who prefers to spend his days perfecting his art of swordplay. (Source: SNK Wikia).
