In ancient Japan, a witch seeks to use the warrior-monk Ningen's enlightened body and spirit to resurrect a demon-samurai and unleash an era of chaos on an already-troubled country. After leaving the safety of his temple to protect poor commoners who are caught in bloody battles between feuding warlords, Ningen soon finds that several colorful bounty hunters are on his trail-seeking his head and his very lifeblood for the witch's twisted spells!
