A hundred years ago, the Great Human-Demon War ended in a decisive human victory. Since then, demons—defeated and dwindled in number—have been enslaved from birth, their existence reduced to lifelong servitude under the rule of goddess-blessed humans. Into this world is reborn Liebe, a human boy who died in a tragic accident after a life of bullying and despair. But fate grants him a second chance—as a demon. Stripped of freedom and forced to serve a nobleman's daughter as her “pet”, Liebe lives a life of submission. Bound by a slave contract, he can’t raise a hand in defiance—until he discovers a hidden ability: a demon’s eye that reveals any enemy's weakness. Using this power, Liebe creates a spell to temporarily override his slave contract, unlocking the path to rebellion. “If I’ve been reborn as a demon... then I’ll become their hope— and rise as the strongest Demon King this world has ever feared!” The curtain rises on a dark fantasy of vengeance, rebellion, and the rise of the weakest species to ultimate power!
