Libra is a curvaceous woman with dark hair tied in an ox horn style. Her attire resembles a belly dancer's, consisting of a frilled and striped bikini top along with a patterned loincloth sporting pom-poms at the waist. She wears numerous bangles on her arms and legs, and her neck is also concealed by a thick necklace. On her feet are a simple pair of sandals, and her head is dressed with a zigzagged headband. Concealing Libra's lower face is another cloth that bears her sign, tied around her head.
Dangling from her hands, Libra carries a pair of scales, with thin cords running from her fingertips to the sides of the scales, so that she holds them in an almost puppeteer-like fashion.
Libra is a very quiet Spirit. She barely talks and always seems calm and serene, however, she quickly obeys Yukino's orders without questioning them.
Gravity Change: Libra uses this type of Gravity Magic which can alter either her target's gravity or her own. She is also able to change the body figure of anyone she wishes.
Immortality: As a Celestial Spirit, Libra cannot die, unless she is somehow forced to stay in the Human World.
Scales: Libra possesses a pair of scales, which aid her in her employment of Gravity Change. Each scale consists of a small golden bowl that is connected to 3 chains, which are also attached to rings that are worn by Libra.
