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.
Cecil is a very passionate person, who often dives headfirst into things without considering the end result. She is shown to be kind, warm hearted, and cordial in nature. Couple this with her young and cute features, and she is often underestimated. Enthusiasm, whether it's for something good or bad, can usually radiate off of her. She is hardworking, and dedicated to everything that is important to her, such as her line of work. She's quick to state her opposition towards something, yet she's also very fast to be supportive of the underdog in the situation. When push comes to shove, she'll always stand up for her friends. She means well, having a reasonable sense of justice, and will make her voice known when she feels something isn't right. Cecil refuses to tolerate impolite behavior, as she is sensitive towards other people and their well-being. If someone is in danger, count on her to be the one to save them.
