The Devil intervened, pulling Kyros into Hell with an irresistible proposition: a second chance at life in a world far removed from Earth—a world named Neva.In this fantastical realm of knights, nobility, magic, and divine power, Kyros becomes the key piece in a wager between God and the Devil. Reborn as Rasmus Blackheart, a disgraced young noble, his task is clear: unleash chaos and topple the order of Neva, just as he did on Earth. But the Devil has added a twist to the game—he’ll serve as Rasmus’s companion, not as a guide but as a mischievous, manipulative force, more likely to hinder than help.Navigating a world brimming with intrigue and divine interference, Rasmus must survive, scheme, and rise from ruin to reshape Neva in his image. Will his cunning be enough to outwit his foes—and his so-called ally—or will this chaotic partnership lead to his downfall?
