Era of Purification

At the dusk of the old era, the evil consequences of human civilization turned into terrifying entities. Pollution engulfs the world, and garbage deforms into monsters called "filth", roaring on the earth and pushing the world to its end. The giant rock statue stood up from the ruins, the beasts of the abyss roared in the oily sea, the poisonous haze covered the sky, and even the daily kitchen waste, bath dirt, and toilet silt all gathered into a nightmare that preyed on people. Humanity, huddled in the last "net shield" shelter, is on the verge of extinction. However, hope is never completely lost. The warriors of the "Terminal Purification Agency" - the "scavengers", "guardians" and "adjudicators" who are equipped with the power of purification - use their lives as their blades and their faith as their shield to hold on to the last fire of civilization. At this moment, a ray of light from the distant future pierced the despairing night.
