The official website describes her as "Has a Japanese father and a French mother. Highly skilled, she has often performed on stage since she was a young child. However, since joining Seisho Academy, the powerful presence of Maya has formed into something of a rival for Claudine." 

She is a top student at Seisho academy, second to Maya, and seeks to outdo Maya and become the best in their class. 

Her voice is about medium range with hints of pretentiousness. Claudine also speaks fluent French and has a tendency to say French words and phrases in her lines, so we request that anyone auditioning for Claudine have some knowledge of French, we do not require you to speak the language or be fluent but we want you to be able to pronounce any French terms she uses correctly.
