Ultina D'Monique Lane (ウルティナ・ディモニーク・レイン Urutina Dimonīku Rein?) also known as Demonica (デモニカ Demonika?), is a member of the aristocratic Lane family in Kalise. She was kidnapped at the age of ten by Chienne de la Punition and made D'Monique a member of the Mistresses of Doom. Chienne also changed D'Monique's name to Demonica. Demonica later became a member of the Tribe of Darkness with the rest of the Mistresses of Doom. When the Kalise Castle exploded during the climax of the Kalisian War, Demonica survived and believed that all of her comrades died. Because of this, Demonica became paranoid and believed that if she killed King Anthony to avenge her comrades' deaths, the will come back to life. To escape suspicion, she used her original first name, Ultina. Later, during Diavolo's War, she finally encountered King Anthony and fought him but finally met her fate when King Anthony delivered a fatal blow to her.
