Claire is a young woman with long black hair and red eyes, a tall, slender figure, and fair skin, with a voluptuous chest, and shapely legs. She bears a red magic seal on the back of her left hand, that she conceals with white bandaging.

She currently wears a light blue cardigan, a white dress shirt, and a dark blue high waist skirt with a side slit that exposes her left thigh, which has a black thigh strap on it.

She deeply loves her younger brother, where it becomes a deep brother complex.
