Edea Matron - as she's called by the children of the orphanage. The SeeD members and Edea once stood as enemies before they all realized the truth. Having, of course, no parents that she know of, Edea was the mother figure Quistis looked up to and loved like one. Edea cared for all the children of the orphanage and after the bout between her and SeeD was over, they looked at her once again as the woman that cared for them long ago.
Cid The headmaster of Balamb Garden, he was the one who appointed Quistis as an instructor at such a young age but also is the one who strips her of her title. However, she respects the man for being a positive role model in her life and taking care of her when she entered the Garden.
Unknown Family At the age of 9, Quistis was adopted by a family, however, the adoption didn't go to well, so Quistis joined the Balamb Garden.
