Luceria is the second servant card obtained by Kaito.

Introduce herself as Demon (Viscount)

In contrast to Sylphy, Luceria is more blunt in her speech and mannerisms, openly demanding in a rude tone, although she ascribes much of her rudeness to it being the way demons are and to take no notice of it. Despite which, she enjoys spending time with Kaito, to the point where she will ask where he has been rather than being with her and Sylphy. She acts very much like a tsundere around him and others, secretly enjoying the attention she gets.

Luceria is roughly the same height as Sylphy. She has dark and silver hair tied into twin ponytails which reaches the top of her thighs, pointed elfin ears, black bat-like wings and a black demon tail. She wears a lolita style black and red dress with pastel red stockings with white diamonds below her knees, and black boots decorated with red patterns.
