Mia Winters (ミア・ウィンターズ, Mia Wintāzu?) is a former operative for The Connections who worked covertly in the birth of Eveline, acting as her "caretaker" while covering up her career as a worker at a "trading company" to her husband, Ethan. After being presumed dead in 2014, she was recovered by the Baker family, and resided under lock and key at their property until being re-discovered in mid-2017.

After Eveline's death, Mia and Ethan moved to Europe and started a family.
