Once a revered hero and protector of realms, the protagonist is reborn not as a savior—but as a calamity. In a world torn by ancient grudges between gods and demons, where love between races is a curse and loyalty is fleeting, he returns with fractured memories and a heart poisoned by betrayal. Twisted by love lost, haunted by betrayal, and consumed by vengeance, he becomes the very force he once vowed to destroy. Betrayed by those he swore to protect, his heart now burns with rage and revenge. But can a heart shattered by ruin still change fate? Will he become the executioner of a broken world, or the final ember of what once was light?
