Marcille was petite yet curvy, her figure accentuated by her long blond hair and emerald green eyes. Despite her half-elf heritage, she possessed a set of rounded ears, a small indication of her mixed blood. Her usual attire consisted of a long blue dress, accented with white pants and a red choker. The dress hugged her figure perfectly, emphasizing her curves and rounded rear. Marcille is intelligent, principled, and loyal to her friends. Despite this, she can also be very high-strung and has a difficult time dealing with things far outside her comfort zone (such as eating monsters).[7] She has a lot of confidence in her ability to cast magic due to her background, so she feels insecure when she is unable to help the party with her specialty, to the point where she may endanger everyone just to 'prove herself'.[8] She can also feel a bit self-conscious when using dark magic, which she knows to be illegal, as shown with her nervousness when telling her other party members about her plans to revive Falin. When others look down on her for using dark magic, she has a tendency to feel extremely guilty about it, as shown when she faced Shuro's anger at the methods taken to revive Falin, though throughout this she seems confident that her methods, though taboo, may be the most promising for the future.[9] She can also be somewhat naïve, believing that friendships alone can keep a party together and frequently trying to learn more about her party members and their personal lives, especially when it comes to Chilchuck. She can be very pushy with this, but her intrigue seems to be similar to that of a gossipy teen girl and not anything malicious.[citation needed][10]
