Luea resembles Ruby, but colored black and white and with two pink heart patterns on her body: below her left eye and on her left leg. Her Jewel Eyes are made of blue apatite and she wears an indigo butterfly hair clip and a garland of indigo roses on her neck.
In Lady Jewelpet, Luea is very affectionate to Lillian. She is also very refined, and knows exactly how to give advice to Lillian and train her in the right way for a task. However, Luea is very sarcastic, and often makes sarcastic comments to Ruby, who takes them as compliments instead of insults. Luea also loves to be scratched behind her ears. Luea was Lady Diana’s jewelpet mentor. Luea is very determined to make Lillian Top Lady. Because of this, she has stated multiple times that she will do anything it takes to make Lillian Top Lady.
Luea was left behind by her previous Petit Lady, so she is emotionally scarred and tries to take control and make Lillian successful in order to make Lillian stay with her.
Luea is shown to be good on mentorship, thought however she can be very strict on the Lady she wanted to become Lady Jewel. Although she boasts about her own skills a lot, her mentorship shows through Lillian herself in every Lady test she does.
Aside for her mentor skills, Luea is an expert magician like any other Jewelpets. She can cast dark spells using the Jewelpad, thought it requires a magic key to fully utilize it. This kind of spell, called Tap and Magic, lets her do things to hinder both Ruby and Momona’s progress as Lady Candidates. Unfortunately Luea is not capable of controlling this type of magic and it usually goes berserk. Luea is secretly working for someone so that her dream of making Lilian Top Lady come true.
In Jewelpet Magical Change she has a major role as Laura’s partner.
