Sung-Sun is a slender female Arrancar with long flowing olive-green hair, long eyelashes, and three pink dots just below her right eye. She has lavender-colored eyes. Her mask remnants create three hair clip-like extensions on the right side of her bangs. She wears a furry black necklace around her neck. Her uniform consists of a long white dress with long sleeves that extend well past her hands and with a single slit in each one. The position of her Hollow hole is still unknown. Her Zanpakutō has been shown to be a three-pronged sai, which she conceals under the sleeves of her outfit.
