Setting: The Immortal of Six Paths becomes a false god in order to gain the power of faith and keep his soul immortal. In addition, after death, ninjas do not go to the land of souls, but to hell. Because of all the strong men who were pulled out to "work as coolies" by the reincarnation of the dirty land in the Four Wars, none of them have been reincarnated, and none of them have the memory of the land of souls. This is the setting of hell. The prisoners in hell are unconscious and work mechanically until their souls are annihilated and become part of hell.
Main plot: Defeat the Sage of Six Paths! Let the souls of ninjas after death enter the land of souls and have the opportunity to enter reincarnation.
Intention: Positive and uplifting
