Stripped of everything, facing a fate cruel beyond measure, would you accept a devil's bargain? This question echoes through the story of Ash Grimore, a young man cursed with an infernal ability—the power to enslave others, a gift reserved for mythical devil kings of legend. Branded a threat to the kingdom, Ash concealed his dark gift until love betrayed him. The hero struck him down, claiming his life to prevent a destined apocalypse. Yet in that final breath, salvation arrived from an unexpected source: the voice of the world itself, offering him a second chance through a binding contract. Reborn with purpose, Ash discovers his true mission: to alter the destinies of broken heroines. The system binds them as his slaves, their contracts interwoven with his own growth. As they ascend in strength, so does he. His path forward leads through dangerous quests, revenge against those who wronged him, and the collection of powerful heroines desperate for salvation. But a complication emerges. Each heroine he rescues, each broken soul he heals, begins to blur the lines between contract and affection. What started as a quest for vengeance transforms into something far more complex when every single woman he saves threatens to steal his heart. Can Ash balance his thirst for revenge with the growing bonds forming around him? In a world where slavery and love intertwine, where system contracts blur the boundaries of choice and emotion, one man must navigate the dangerous game of transformation and desire.
