Synopsis

The world as we know it has crumbled, decimated by a man-made virus that spared only the children. From the shadows of this apocalypse, vampires emerged to claim the surface, herding the surviving human youth like livestock. Yuichiro Hyakuya is a survivor fueled by a singular, burning desire: total extermination of the vampire race. After a daring escape from the underground city costs him everything, he finds his way into the Imperial Demon Army. To stand a chance against immortal predators seven times stronger than any man, Yuichiro must master the Cursed Gear—weaponry possessed by volatile demons. However, vengeance is a lonely path, and the elite Moon Demon Company demands the one thing Yuichiro hates most: teamwork. In a twisted landscape of dark conspiracies and supernatural warfare, the battle for humanity's soul begins now.
