Ophelia lives on Anima, an ark where objects have souls. Beneath her worn scarf and thick glasses, the young girl hides the ability to communicate with the souls of objects, and the power to travel through mirrors. Her peaceful existence on the Ark of Anima is disrupted when she is promised in marriage to Thorn, from the powerful Dragon clan. Ophelia must leave her family and follow her fiancée to the floating capital on the distant Ark of the Pole. There, in the presence of her enigmatic future husband, Ophelia slowly realises that she is a pawn in a political game that will have far-reaching ramifications not only for her but for her entire world.
