House Garnet's Archvillain

In the Reindhardt Empire, authority is divided between the imperial family and six influential duchies, each blessed with a unique sacred power. The Duchy of Emerald is the most prominent, largely due to Estelle—the duke's illegitimate daughter who possesses unmatched divine ability. But despite Estelle's benevolence and support from the people, the greedy nobles constantly shun and berate her, eventually sacrificing her to the devil in exchange for their own prosperity. Estelle's pure soul attracts greater violence and mental torment than the average human would receive in the demonic realm. She endures such treatment for six hundred years, but can no longer withstand it. Before her soul vanishes, the devil offers Estelle a deal: she is to return home and turn her abusers' happiness into death, anguish, and screams. Possessing the body of Jewel Garnet—the youngest daughter of the strongest duchy—Estelle begins to unleash her vengeance on the reigning families, leading them straight to ruin.
