In a world where women command demon servants bound by blood pacts, a woman awakens to find herself transmigrated as Lilith Blaine, a noble heiress and villainess trapped in a power-fantasy maiden game. She struggles with her weak demon-taming ability despite contracting four demon butlers. Faced with the imminent betrayal and corruption of her demons—three near a deadly breaking point—she learns that her fate is to be killed by one of her butlers, Jormund. To survive, she must convert the demons’ corruption into affection, forcing a desperate and urgent quest to change her doomed path.
