Guardians, those who have swore to protect humanity's freedom even at the cost of their own lives. This is who Takiaya is-or was. Now everything has changed. Only a scarce few of the Guardians remain, and Takiaya can't bring herself to trust another human again, not after what happened. But when one boy saves her, she can't help start to wonder. Is all of humanity as cruel as she thought? And if not, is there some good still worth saving?
