My Shadow Guards Are All Yandere Empresses

A Demon Lord reincarnates as the Ninth Prince and gets shackled with a "Good Person" system—but his brand of kindness is a predator's trap. He gifts miracle elixirs to bind grateful maids in invisible chains, rescues fallen geniuses only to break them into loyal hounds, and offers warmth to desperate souls before watching them burn. Beneath silk robes and gentle smiles lies a master manipulator who turns compassion into control. As the imperial palace becomes his hunting ground, even the system that meant to reform him becomes another tool in his arsenal.
