Karui is a dark skinned kunoichi with long spiky red hair and amber eyes. As noted by Omoi in Part 2, she was flat chested. She wears a long, short sleeved dress with frilly edges complete with the Kumogakure flak jacket, two simple yellow earrings, fish-net stockings, thigh-high boots with white soles and a forehead protector which she wears like a bandanna. She also wears gray wrist arm bands that cover her wrists during the war in the manga. She carries a sword long sword on her back.
As an adult, Karui is no longer flat chested. Her hair grew fairly longer. Her attire now consists of a long sleeved dark dress and a white girdle covering her stomach. She also no longer wears her forehead protector and sets her hair in a more neat back-comb style. Karui changes her earrings to dangling earrings in the same color.
