During the peaceful Edo Era, Lord Tokugawa Tadanaga organized a fighting tournament. Unlike previous matches that were fought with wooden swords, real swords were introduced. The competition featured One-armed Fujiki Gennosuke and blind Irako Seigen, both trained by Japan's greatest swordsman, Iwamoto Kogan. The two disciples sought to become Iwamoto's successor, creating an intense rivalry to claim the title. As fate would have it, only one could emerge as the victor. Thus, a story of intertwined destinies, conflict, and peculiar outcomes began.
