Year 2056, in a city in the Yuan Jiang Su Jin area. On top of a ruined, shattered six story residential apartment sits a teenager wearing a combat vest, militaristic trousers, and alloyed battle boots. On his back is a hexagonal s.h.i.+eld and equipped is a blood-shadow battle knife. He sits there silently on the edge of the roof. At this time, the sparkling sky was s.h.i.+ning and there was a refres.h.i.+ng breath within the air that blew towards him. However, there was only silence within the ruined, deserted city, with an occasional howl that makes your heart skip a beat.
