In 2030, humanity faced its first true collapse…not by war, but by the sudden invasion of Nightcrawlers, creatures emerging from darkness itself with the desire to devour sunlight at all cost for their evolution.But, they could not absorb it directly since it was as deadly to them as to a shadow under the noonday sun. They could only absorb the sunlight from lifeforms or through signing a nocturnal contract to possess their bodies, providing them with direct sunlight immunity.Within twelve hours, over four billion people perished as Earth was split between eternal night and day.Just as extinction loomed, Holy Light Pillars descended from the heavens, purging one thousand cities from Nightcrawlers and offering humanity sanctuary under their divine light.A century later, in the Heliodor Region, an innocent child found his world turned upside down after two mysterious nightcrawlers invaded his home, slaughtered his parents, and ripped his eyes out of their sockets, leaving him permanently connected to the Shadow Dimension, the home ground of Nightcrawlers.Was it just a random feeding session for them, a planned assassination, or it goes deeper than this?Follow Levi’s journey as he weaves between darkness and light, chasing the truth hidden in both.
