A girl passing as a boy, fourteen-year-old Kira is left to fend for herself alone in this world. During a crucial turning point in her life, she makes a pact with a mystical entity, which grants her the chance to step into a bigger world. From a commoner to a page boy, then to a knight who leads others into battle, Kira matures through trials and tribulations. Yet, she's a mere pawn—an expendable being in the chess match between powerful men without any control over her own destiny. With no one to count on, can our heroine be able to change the fate others have chosen for her?
