Shirabe has light pink eyes with long, straight black hair in a hime cut. Her hair is held in two pig-tails tied with pink ribbons. She is most often seen wearing a pink and black long sleeved dress with dark pink stockings and black boots. When briefly possessed by Finé, she gains her distinctive catlike eyes.
