Youkou no Ken - Season 1

In a period of feudal conflict and division, Matagoro Yoshimura accepts a commission from regional lords. His objective is a substantial hidden treasure. The location, however, is fragmented across a series of map pieces, each concealed on the person of a different female ninja operative. These markings become visible only under specific conditions of physical arousal. Yoshimura must therefore engage with these agents to assemble the complete guide and secure the prize.
