Diane is a largely cold and reserved yet sweet woman, she has a relatively slender yet curvy body, white white skin, often seen wearing a tanktop and blue Jean's. but most notable of her appearance, is Diane's extremely long and thick beyond floor length mane of brown hair that trails across the ground behind her most of the time as the length of her hair extends far past her own body length in 3.6 meters pooling around her, though she keeps her hair in a bun most of the time.
