A world filled with heroes with superpowers. A world attacked by calamity fiends. A modern world filled with wonders and dangers.

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 shield and equipped is a blood-shadow battle knife. He sits there silently on the edge of the roof.

However, there was only silence within the ruined, deserted city, with an occasional howl that makes your heart skip a beat.
