Cyan Sung-Sun

Sun-Sun (スンスン, Sunsun) is an arrancar in Sōsuke Aizen's army. She is one of Halibel' three female Fracción.

Character outline
Sun-Sun dresses somewhat like Luppi, with sleeves that extend well past her hands. She also has two belts criss-crossing each other on her waist. Sun-sun has long, flowing green hair and three dots below her right eye. Her mask remnants create three hair clip-like extensions on the right side of her hair. Her hollow hole isn't visible. She seems to be the most mature of Halibel's Fracción, advising Apache and Mira Rose to stop arguing, as it makes them look weak, then chiding their angry responses.

Synopsis
She and and the other two Fracción, appear with Halibel and the other two strongest Espada in the fake Karakura town to do battle with the Gotei 13.
