For years, a great war has raged between the scientifically advanced Empire and Nebulis, the realm of the magical girls—until the youngest knight ever to hold the title of the Empire's strongest meets the princess of the rival nation. Though sworn enemies, the knight is captivated by her beauty and dignity, and the princess is moved by his strength and way of life. Will their battles ever be allowed to end?
