Éléonore is Louise's and Cattleya's eldest blonde sister. She has her father's blonde hair and resembles him more than her mother. She also inherited her father's personality, which is stronger even than Louise's own personality. Éléonore brought Louise out of the magic academy with the intent of finding her a Noble husband. It should be her turn to get married instead of Louise, and she had gotten engaged to the Count de Burgundy, though he called off the marriage. Like most the rest of Louise’s family, except for Cattleya, she believes that Louise is incapable of performing magic because everything she does blows up, and that she is a zero.

The Familiar of Zero
Meet Louise, a budding magician. The students at the Tristein Academy call her "Zero Louise", due to her current record of zero successes with magic. In fact, her magic tends to go spectacularly wrong. Now, as an important test of her aptitude for magic, she must summon a familiar to be her servant. At this critical moment, she summons up all her magic and wishes for a familiar that is "devoted, beautiful and powerful", and gets... Hiraga Saito, an ordinary Japanese boy. It's difficult to say who is more surprised and dismayed, but the rules don't allow for second attempts. Louise is stuck with her strange familiar, and he with her.
