Cecil is of Canadian descent, and so is said to look like a foreigner. She has lavender-colored hair—part of which is kept in twin braids, while the other is noticeably shorter, styled in a high pigtail fashion with pink bows—and straight bangs across her forehead. Her eyes are light blue. Her debut outfit is a pink seifuku uniform shirt, a leather bomber jacket with the letter "C" on the left breast, a violet skirt with white horizontal stripes and a sea green laced hem, lacy pink socks, and brown ankle boots accented with small pink bows.
