Manji is a rough and bloodthirsty warrior with a special ability – he won’t die.Due to the cold-blooded and ruthless killing in the past, he was cursed by a nun named Night Bat and gave immortal life as punishment.The long years made him feel bored and exhausted by this endless existence.Only by killing a thousand sinful people can this curse be lifted and he can regain the "redemption" of death.So he wandered all over Japan alone, swinging his sword in the darkness, paving a path to the end with evil blood, just to feel the finiteness and reality of life again.
