A Hero's Ultimate Betrayal Becomes His Darkest Power The world's mightiest Hero accomplished the impossible—slaying the Demon King, a force of destruction no warrior had ever conquered. Victory should have been eternal glory, yet fate had other plans. In his moment of triumph, those closest to him revealed their true faces. His girlfriend, his allies, the very organization he'd bled for—all turned their blades against him. The ambush was merciless, the trap absolute, and his noble struggle ended in death. But death was not his final chapter. Consciousness returned in an unexpected form: reborn as a demon, stripped of his humanity yet granted newfound power. The shock intensified when he discovered his new reality—he was bound to the Demon Queen as her royal consort, a position filled with danger, political scheming, and those who sought to exploit his uncertain status. Survival in the demonic realm demands more than strength; it demands cunning, alliance, and the willingness to embrace what he once fought against. As adversaries circle and the court plots to destroy him, he must navigate treacherous waters between his human past and demonic present. Only then can he uncover who orchestrated his downfall and claim the vengeance he's earned.
