The world of Remnant is filled with horrific monsters bent on the destruction of humanity. Fortunately, the kingdoms of the world have risen to combat these forces by training powerful Huntsmen and Huntresses at academies around the planet. Ruby Rose, Weiss Schnee, Blake Belladonna, and Yang Xiao Long are four such Huntresses in training whose journeys will take them far past the grounds of Beacon Academy.
