Lillian

A Queen Candidate for Jewel Land. She seems to be the top candidate. It seems that she has a massive crush on Cayenne, and it was said that they were soul mates destined to be apart.

Refined and elegant, Lillian is often quiet around others. However, unlike Charon, Lillian is more mysterious and less shy. Lillian is also shown to be jealous of Momona and Cayenne's relationship, resulting her to be a little too blunt.

~!In a plot twist, Lillian is revealed to have been originally a doll that Lady Diana had owned, but forgot to take it when she had left Jewel Palace. This lead Luea into accepting a deal with Joker, in which if she can do his bidding then she can be happy. Luea used her magic to bring the doll to life and call her "Lillian," and also inserting fake memories into Cayenne so she can be his brother. She was also illegally been registered in the Jewel Palace Database by Luea, in hopes that she can fulfill Joker's plans.!~
