Cécile Croomy

Cécile Croomy (セシル・クルーミー, Seshiru Kurūmī), 24 years old (25 at R2), is one of the Lancelot's developers and Lloyd's assistant. She is a capable scientist in her own right, having designed the Energy Wing system used on the Guren S.E.I.T.E.N. Eight Elements-Type and the Lancelot Albion.

Cécile is a kind-hearted woman and a good friend to Suzaku Kururugi, often helping him with homework. She also acts as Lloyd's conscience, not hesitating to scold him or physically punish him for his unintentionally rude remarks. Cécile is a capable Knightmare Frame pilot, managing to single-handedly hold the entire contingent of Black Knights sent to occupy Ashford Academy during the Black Rebellion at bay using a customized Sutherland modified with equipment from the Lancelot. Prior to joining Lloyd in the military, she studied at the Imperial Colchester Institute. A recurring joke is that Cécile is a bad cook, which no one has the heart to tell her: her recipes includes onigiri mixed with blueberry jam and sandwiches made with ginger, sugar, and wasabi.

Following Lelouch's ascension to the throne, she follows Lloyd and Suzaku and willingly accepts Lelouch as the new emperor. She works with Lloyd and Nina to create a countermeasure to F.L.E.I.J.A. and proceeds to assist Sayoko during the rescue of the hostages on board the Avalon under Lelouch's order. She is later seen incarcerated with Rakshata and Lloyd. She and Lloyd are last seen in Viletta's wedding picture.
