Manji, the Slayer of Hundreds, has been cursed with eternal life - but in the dark of his existence shines a final glimmer of hope. If he can slay 1,000 evil men, Manji will finally be able to end his life of infinite misery. When a young girl named Rin asks him to help her take revenge on the group of master swordsmen who slaughtered her family, Manji finds some resemblance to his lost younger sister in her and decides to come to her aid.
