The Kisōshi, elite warriors with elemental powers, have served as the rulers and protectors of the people of Gensokai for more than a thousand years. Though it is believed throughout Gensokai that there is no such thing as a female Kisōshi, the Rōjū ruling council goes to great lengths to ensure that no one dares ask why. Even as young girls, Mishi and Taka know that they risk severe punishment - or worse - if anyone were to discover their powers. This shared secret forms a deep bond between them until, taken from their orphanage home and separated, the two girls must learn to survive in a world where their very existence is a crime. Yet when the girls learn the dark secret of the Rōjū council, they discover that much more than their own survival is at stake.
