Representing the fallen angel Lucifer and the corresponding sin of pride, she is the eldest among all the Stakes of Purgatory and acts as their leader. Lucifer is based on the servant Ruon. She is extremely insecure, knowing herself to be the most inferior to her sisters, and fears what they would do if they found out. As such, she acts arrogant and conceited to keep her weaknesses from being discovered. Despite that, she takes pleasure in surrendering on her own accord. Lucifer's appearance is a girl with long, straight black hair.
