Muriel Besson is a young French student with a keen interest in the Japanese culture. Her brother, Frank Besson, is the boss of a Milieu, who spoils her very much.
During Masamune's trip to France, she uses him as her model of her hero, and Aki as the heroine.
Muriel has medium length blonde hair that is usually tied up, and blue eyes. Her right eye is usually covered with a black eye patch, with a white rose symbol on the patch. She has a black tattoo on the upper left side of her back.
