Luceria

Luceria is a Viscount-class demon who serves as Kaito's summoned familiar. Known for her haughty attitude and biting remarks, she harbors an intense fixation on magic cores and frequently causes her master grief through her self-centered behavior. She excels in highly destructive magic and is capable of transforming into a mature combat form. Though she often clashes with Silphy in a rivalry for their master's attention, she consistently reveals her loyal and considerate nature toward him when it truly matters.
