However, in this body, reborn the strongest dark magician and demonologist - the one who killed the Emperor, equal to the gods - Evan Lynch. Upon awakening, Evan realizes that his powers remain with him, his demon lords, and countless studies. Evan had accomplished his goal, but that didn't mean he was going to stop. Now it was time to learn how a new world worked with things unknown even to him, yet saturated with despair and terror - the perfect place for him. His pride and the flames of revolution had led to him receiving one of the seven deadly sins - a special power that had yet to be earned on a dangerous path.
