In the heart of the Sengoku era, an age of endless conflict, one name thundered across the waves: the Murakami Kaizoku. These pirates, masters of the Seto Inland Sea, were led by the immensely powerful Takeyoshi Murakami. But it was his daughter, Kyo, who truly inherited his fierce courage and untamable spirit. Devoting her life to piracy and battle, Kyo is infamous in her hometown as a fearsome, ugly shrew whom no man would dare make his wife. The tale begins as this unlikely princess sets a course for Naniwa on the eve of a decisive battle, a journey that will plunge her into the heart of history.
