When Nightcrawlers descended upon the world in 2030, humanity's survival hung by a thread. These creatures of darkness sought sunlight for their evolution, yet couldn't absorb it directly—its rays proved as destructive to them as shadows to a creature of day. Only through consuming lifeforms or binding nocturnal contracts could they gain sunlight immunity. Within twelve hours, the world fractured: four billion people fell, and Earth split between zones of eternal darkness and endless light. Salvation arrived through Divine Light Pillars—heavenly structures that annihilated Nightcrawlers from a thousand cities and granted humanity refuge beneath their protective glow. One century later, in the Heliodor Region, young Levi's life shattered in a single night. Two rogue Nightcrawlers infiltrated his home, slaughtered his parents, and tore the eyes from his sockets—forever binding him to the Shadow Dimension, the very realm where Nightcrawlers originate. Was this mindless slaughter, orchestrated assassination, or something far deeper? Levi's path now winds through shadow and light, seeking the truths hidden within both realms and the answers his past demands.
