Yasuko, a housewife, lives in an urban high-rise apartment with her husband Satoru and her son Takuto. Annoyed by spam calls and door-to-door salesmen, Yasuko slams the door on a salesman’s hand when he tries to squeeze a flyer through the apartment's chained front door. He leaves, but the next day, her nightmare starts.
Jigoku-gokuraku-maru is a samurai on the run. One bounty hunter hoping to collect the sizeable reward is Teppo Oyuri, a comely lass who is an ace shot with her pearl-laden pistol. Before she can set her sights on Jigoku-gokuraku-maru, he is attacked by a hoard of sword-wielding thugs also hoping to collect the reward. He dispatches them with bloody aplomb. Later, Jigoku-gokuraku- maru and Teppo Oyuri -- who has fallen for the master swordsman in spite of herself -- ventures to Zipingu -- the Land of Gold -- in search of a magical gold sword.
