The Unseen Agency: Humanity's Last Stand

Humanity thrives, blind to the million-year war that raged before. Ancient gods, devils, and yokai vanished, leaving us believing in a safe, rational world. But Xie Zhifei knows the truth: the 'inexplicable' never disappeared. A brutal incident thrust him into the shadows, a secret war against the 'weirdness' that preys on the innocent, monsters born from twisted urban legends. Now, as a scarred agent of the Human Security Agency—the 'Fool's Blade'—Xie Zhifei wields crimson threads, a unique power to dissect these absurd entities. But strange phenomena are escalating. An unprecedented surge of low-level weirdness signals a terrifying truth: something far older and more dangerous is stirring, threatening to shatter the fragile normalcy humanity clings to.
