Sakura

Pink's older sister

Raised by her mother, Lumia. Sakura is quiet and generally doesn't have anything nice to say. Total tsundere when she grows attached to someone! She has a massive crush on her mother's best soldier; Archangel Micheal. The two have never spoken, but the girl frequently stalks him. The archangel believes the energy following him to be Lumia herself, so he is always on his best behavior. 

Sakura is quick to flee from a situation she doesn't feel ready for, and avoid any kind of conflict with someone she likes. She can be very aggressive with everyone that isn't in that category.
