Null Shadow: The Contract Devourer

In a city where destiny is decided upon turning eighteen, everyone signs a Shadow Contract. Beasts. Weapons. Supernatural powers. The contract defines your value… or your doom. Cael obtains nothing. His shadow does not shift, does not awaken, and does not respond. The system classifies him as Grade Zero—an error that shouldn't exist—and discards him without hesitation. His family turns their backs on him. Society erases him. He is cast into the Purge Zone, a place where failures vanish alongside their wielders. There, Cael is supposed to die. But when he is attacked by another outcast, the impossible happens: His shadow detaches from the ground and devours the other's shadow. What the system called "null" is, in reality, a primordial void capable of extinguishing contracts. A power that shouldn't exist… and one that no one knows how to stop. Now, Cael must survive by feigning weakness, learning to move within the shadows of a city that watches his every move, all while hunting in secret to delve deeper into a darkness that threatens to consume him from within. Because if the world discovers what he truly is… It won't try to control him. It will try to eliminate him.
