The Lone Warrior chronicles the journey of Hanshiro, a master samurai who carries the most coveted weapon in all of Japan - a legendary sword that prevents its owner from dying in combat. For Hanshiro however, this extraordinary gift came with a price. The sword possesses a curse that deprives him from achieving any joy or honor from fighting, and has caused him to resign from the samurai lifestyle and become a vagrant traveler. When Dorin Munesuke, a prominent samurai lord, discovers Hanshiro's whereabouts and beckons him to fight once more, bloody conflict erupts between the two men to determine if Hanshiro will regain his honor.
