Claire serves as the current Lady Jewel and essentially the mentor figure of the series. She's the one who welcomes Momona and the other Petit Ladies when they arrive in Jewel Land, and she stays involved throughout by setting tasks for them and offering guidance and support. The girls look up to her, and after the first episode, she communicates with them through Lady Lecter, her messenger, who delivers notes via Magic Letterpen.
In the anime, Claire is portrayed as strikingly beautiful with very long blonde hair, bright blue eyes, and an air of elegance that matches her outfit—a light purple and white frilly dress paired with a veil. She wears a dark purple collar adorned with an emerald heart, matching emerald earrings, and a crown with a delicate chain holding a small emerald that drapes across her forehead.
Her personality matches her refined appearance. She's genuinely kind and gentle, carrying herself with natural grace and poise. What makes her effective as a mentor is that she actually knows how to teach—she's skilled at showing the Petit Ladies what it takes to become a proper lady, and she does it in a way that feels encouraging rather than condescending.
