In a world where monsters lurk hidden in the city of Salem, the population lives in fear while the government dismisses and hides the threat. Citizens face despair and fear, but the government refuses to acknowledge the existence of the monsters and forbids any form of defense. Instead of protecting the people, the government prioritizes capturing the monsters to subject them to experiments and develop biological weapons. In this context, Daemyn Brown (Dark Human), an individual sent by a cult with the mission to eradicate the monsters, and Adam Mirren, an agent of the organization in charge of capturing the monsters and delivering them to the government for its experiments, cross paths. Although both pursue opposing goals, neither is completely sure of their true mission.
