セシル・クルーミー

Cécile Croomy is Lloyd's subordinate in Camelot and one of the Lancelot's developers. She is a capable scientist in her own right, having designed the energy wing system used on the Guren Seiten and the Lancelot Albion, and also a capable Knightmare Frame pilot. Prior to joining Lloyd in the military, she studied at the Imperial Colchester Institute. A kind-hearted woman and a good friend to Suzaku, Cécile often helps him with homework. She also acts as Lloyd's conscience, not hesitating to scold him or physically punish him for his unintentionally rude remarks or treating Suzaku as a "part" of a machine. A recurring joke is that Cécile is a bad cook, though no one who eats it (e.g. Lloyd) points that out to her.
Following Lelouch's accession to the throne, she willingly joins Lelouch's new regime. C.C. deduces that Cécile's reason for doing so was because she had fallen in love with Suzaku, Lelouch's Knight of Zero.
