Éléonore de la Vallière

Éléonore Albertine le Blanc de la Blois de la Vallière (エレノア・アルバーティーン・レ・ブラン・ド・ラ・ブロア・ド・ラ・ヴァリエール, Erenoa Arubātīn re Buran do ra Buroa do ra Variēru) is Louise's and Cattleya's eldest blonde sister. She inherited her father's personality, which is stronger than Louise's own personality.

Character History
Éléonore is the eldest daughter of Karin de la Vallière and the Duke of La Vallière. She is very strict, especially to her youngest sister Louise, whom she looks at as a noble who cannot perform magic. She is also ill-tempered to Saito at first because he is just a plebeian. Despite her age, Éléonore was not married but was engaged to the Count of Burgundy who cancelled the supposed wedding.

Like her younger sister, Cattleya, Éléonore previously worked at Oriz Academy of Magic, but worked temporarily as a professor at the Tristain Academy of Magic as ordered by Henrietta de Tristain to teach the students how to perform magic.

Éléonore attended Louise's and Saito's marriage together with her mother and her other sister.
