1. I've Been Waiting for this Day

On his first day as a member of ARKS, Ash, a man on a journey of self-discovery that is plagued by a recurring dream of a woman that speaks of fate, is recruited into the Oribe Unit where he meets a fellow comrade named Afin, whom insists on calling him "partner." The two find themselves in a dangerous situation when the unit is ambushed by falspawn and slaughtered. Able to escape with the help of experienced ARKS members, Zeno and Echo, the group comes across a mysterious white-haired girl and an even more mysterious masked man intent on killing her.
