SAT 8 is from girls frontline.

S.A.T.8 is a gentle and delicate good-girl type by nature, but leaving it at that would be terribly boring. Before becoming a tactical doll, she was a domestic doll who specialized in being dispatched to various places to serve as a temp worker.

She has also worked as an animal breeder, and many jobs.
