A member of the Bird Squad, she is first mentioned as the object of Chouchou's affection. As her name suggests, she wears a duck-like uniform. She fights Emonzaemon while letting her leader and Penguin flee.

Her Ninpou proves to be a hassle for him as he cannot sneak up on her. But she's later gunned down by Jyu, which were in Emonzaemon's possession at the time.
