In the year 2056, in a city located in the Yuan Jiang Su Jin area, a teenager sits atop a ruined six-story apartment. He wears a combat vest, militaristic trousers, and alloyed battle boots. A hexagonal shield rests on his back, and a blood-shadow battle knife hangs at his side. He sits quietly on the edge of the roof, looking out at the sparkling sky. A refreshing breeze blows toward him, but the city around him is silent. Occasionally, a distant howl echoes through the air, sending a chill down his spine.
