In 2085, a sudden meteor shower threw Earth's ecosystem out of balance. The meteors brought destruction, but also parasites from outer space. Anyone or anything that was infected, whether human, animal, or plant, living or dead, turned into a mindless walking corpse. In less than a month, some had not only developed consciousness, but even evolved intelligence. With humanity's weapons powerless against these evolved monsters, the World Science and Technology Alliance used parasite cells from the creatures to develop an armored biochemical weapon called the "Divine Armor." It also formed the "Destroyers," who established survivor camps called "Hope" in countries around the world. At last, humanity had the means to fight back against the monsters. The male protagonist is an unaffiliated Divine Armor user. Can he lead humanity back to civilization, or will he bring about its destruction alongside the ever-evolving monsters?
