The previous Maoh and mother of Wolfram, Conrad and Gwendal, each with different fathers. Although initially, Cecilie seems to be rather airheaded, she is actually very astute and intelligent and a very caring person. Having been replaced as the Maoh by Yuri, Cecilie takes advantage of her open schedule to hunt for men on her "free and easy quest for love." She has displayed interest in Yuri (though she remains one of the chief supporters in his engagement to her son, Wolfram), his older brother Shori, and even her childhood friend Raven. At one time, she wanted to marry him, much to her brother's chagrin. Cecilie is also quite powerful, and has admirable skill with the whip. When fighting, she has the uncanny ability to quickly dress in red leather and mask. This form and her skill tends to scare her enemies, and if they ever meet her the second time, they are usually unwilling to fight her again.

Cecilie likes flowers and grows new types of them in the Blood Pledge Castle. She also names them, examples being "Beautiful Wolfram（麗しのヴォルフラム）", "Secret Gwendal（内緒のグウェンダル）", "Conrad Stands Upon the Earth（大地立つコンラート）", and "Cecille's Red Sigh（シェリの桃色吐息）", and also, in season 3 she makes a new one which she called "Filled with Yuri's Naivete"

She can take control of situations easily and effectively, however, and cares for her sons deeply, despite her cheerful personality. When Wolfram temporarily dies, she is devastated, and throughout the series she can be seen doing her best to protect her sons without directly interfering.

Cecilie goes by the name "Celi", which is pronounced "Cheri" in Japanese. Because of that some fans call her "Cheri" while others use "Celi" (Pronounce as "Tseri"or"tselli' accurately in Romanization of Japanese). Both spellings are acceptable however, and thus depend on personal preference.
