Gw mau tau Eleonore dan Cattleya dari Daftar karakter The Familiar of Zero

and  are Louise's older sisters.

Eléonore is very strict, strong-willed, and even uses a whip. Her personality is stronger than "Chibi-Louise's" in all aspects, except that she looks down on commoners such as Saito. She has a passionate nature sometimes expressed through her dreams; after her engagement was called off by her lover, she becomes infuriated whenever the topic comes up, insisting that Louise get married. She and Cattleya join the magic academy during the second anime season to watch over Louise. By the end of season 4, Eléonore finally accepts Louise's feelings for Saito.

Cattleya is more easy-going and gentle towards Louise and her friends than Eléonore, and Saito notes the latter also has a large chest. She uses Earth magic and is often seen with a variety of small pets and animals. She is also introduced in the second season of the anime. More than anything, she longs for Louise’s happiness, and is fine with the fact that Louise has feelings for Saito.

The sisters' character CD, which they share with their younger sister Louise, was released on 24 October 2007.
