There are some who believe that the honor of a samurai is reserved for men. But they are wrong. Keiko was born the daughter of a samurai. But as a mere younger sister, her future was to run errands for her lovely elder sister and obey her father. Until the day her brother thought it would be amusing to teach Keiko the way of an onna-bugeisha-a warrior woman of the samurai. As a samurai, Keiko finds a new place in the world. One where it suddenly falls on her to defend the honor of her family. After her sister is disgraced, Keiko travels to the Floating World, Edo's pleasure district, not only for vengeance, but for her first taste of the world outside her home.
