Cyan Sung-Sun

is an Arrancar in Sōsuke Aizen's army and one of Halibel's three female Fracción.

Character outline
Sun-Sun is a slender female arrancar with long flowing green hair and three pink dots just below her right eye. Her mask remnants create three hair clip-like extensions on the right side of her hair. She wears a long white dress with long sleeves, somewhat like Luppi's, that extend well past her hands and with a single slit in each one. She also wears two belts criss-crossing each other on her waist and a fury collar around her neck. Sun-Sun not been shown to carry a zanpakutō and the position of her Hollow hole is still unknown.

Sun-Sun appears to be the most composed and mature of Halibel'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 habit of covering her mouth with one of her long sleves and has an incomprehensible look in her eyes when doing so.

Hueco Mundo arc
Sun-Sun makes her first appearance alongside Halibel and the rest of her Fracción observing the battle between Ichigo Kurosaki and Grimmjow Jeagerjaques. As the battle intensifies between the two, Halibel responds to her Fracción's unease that being afraid of an Espada's released form is simply a natural reaction.

Fake Karakura arc
Later she, Apache and Mila-Rose appear alongside Halibel in the fake Karakura Town along with other two strongest Espada and their Fracción to do battle with the Gotei 13.

After the pillars that keep the real Karakura Town in Soul Society are successfully defended and four of Barragan's Fracción are killed, all the other Fracción pair up against a shinigami and begin to battle. Sun-Sun, Apache and Mila-Rose team up against Tōshirō Hitsugaya and Rangiku Matsumoto. However, Matsumoto decides to take on all three whist her captain handles Halibel.

During the fight, Sun-Sun shows that she is the most intelligent of the three by telling them not to touch the ash made by Haienko. She then along with her comrades created a triple cero blast to get out of a ash twister.
