A strong country, Guroman, attacks and overtakes the country of Kukurit, though the particulars of when and where this happens are not given. As a means of keeping the peace, the two countries exchange their third prince and princess, respectively.
Prime Rose, the third princess of Guroman, is placed in the custody of a noble family of Kukurit under the name of Emiya. She grows up into a self-centered high school student.
Although Emiya is favored by Prince Pirar of Guroman, she becomes a girl wanted by the authorities for her aid to the people of Kukurit reacting against the oppressive government. She is saved by the sword master Jimba, and flees to the wilderness.
