About

Sun-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.
Sun-Sun appears to be the most composed, mature, and intelligent of Harribel's Fracción, such as advising her fellow Fracción, Apache and Mila-Rose, to stop arguing, as it makes them look weak, then chiding their angry responses. She has a sort of snobbish attitude toward her fellow teammates. She easily gets them riled up by taunting them and putting her hand in their faces as if she's ignoring them. She has a habit of covering her mouth with one of her long sleeves and has an incomprehensible look in her eyes when doing so.
