In a world where women harness demon-taming powers and men serve as demon servants, a woman wakes up to find herself transmigrated as Lilith Blaine, a villainous noble who contracted four demon butlers but failed to control them. The original Lilith was killed by her corrupted demons. Now, the new host faces the threat of dying as three demon butlers near full corruption, which triggers fatal rebellion. Urged to save one demon named Jormund before he breaks free and kills her, she must act quickly to convert their corruption into affection to survive. The episode ends as she reluctantly begins her risky conquest of demons.
