I Must Become A Monster is a gritty supernatural action manhua set in a world plagued by "Aberrations"—monstrous entities that feed on human life. The story follows a protagonist who, after a traumatic encounter that claims the lives of his loved ones, realizes that standard human weapons are useless against these nightmares. To hunt monsters, he makes the ultimate sacrifice: he chooses to shed his own humanity and merge with the very darkness he hates, undergoing a horrific transformation to gain the power necessary for revenge.

The series is defined by its dark, visceral art style and its exploration of the mental toll of losing one's self. As the protagonist descends further into his monstrous form, he must walk a fine line between being a savior for humanity and becoming the very predator he vowed to destroy. For fans of dark fantasy, psychological horror, and anti-hero protagonists who are willing to sacrifice everything for power, I Must Become A Monster offers an intense and uncompromising journey.
