The Reincarnated are beings that threaten to break the peace of the world. Blessed with the transcendent power of cheat-like skills, they rampage freely, doing as they please.

A young boy, Rai Conwell, lost his family and everything he had when a reincarnated burned his village down. Drowning in despair, he swore vengeance, "I will never forgive the reincarnated."

Years later, after undergoing relentless training, Rai becomes a Purge Knight, a warrior specialized in hunting down the reincarnated. With swordsmanship and physical prowess that surpass even their cheats, he completely overwhelms them.
