The six warriors search the feudal province of Edo questing for the last Saint Soldier, Haohmaru, and their sworn nemesis Shirou Amakusa. Will the followers of the divine light triumph over the forces of darkness, or is history destined to repeat itself? Before their hundred-year journey has ended, six samurai will prove that the only thing stronger than their holy blades is the steel of their wills!
