In a world ravaged by a monster invasion fifty years ago, humanity clings to survival within walled cities while hunters venture outside to combat the threat. Among them is Zack, a young man who wanted to become a hunter despite his lack of awakened traits, a crucial aspect for hunters to harness their powers. For three years, Zack struggled in the hunter's academy, unable to awaken any traits, unlike his peers who swiftly manifest their powers and even join guilds. Despite the setbacks, Zack's determination remains unwavering until the very end. On the last day of school, when hope seems almost lost, Zack's dormant trait finally awakens: the cheater trait. With it comes the extraordinary power to learn cheat skills, a rare ability never seen and understood by anyone. Armed with his newfound power, Zack sets out on his journey as a hunter, determined to prove himself and protect what remains of humanity. Along the way, he will face not only the monstrous creatures that threaten their existence and others who envy and fear his power but also the challenges of mastering his unique abilities and discovering his place in a world forever changed by the invasion.
