Two ninja brothers, Pyun Pyun-Maru and Chibi-Maru, work at an office that will take on any request that comes through its doors. Much of their work means sorting out strange incidents stirred up by other ninjas. Pyun Pyun-Maru acts as a kind of ninja detective, and he and his friends battle crime when they are not tripping over one another. The result is a zany comedy from 1967, running 26 episodes.
