Mia Fey is a defense attorney who appears in the second season of the Ace Attorney anime. She is introduced as the boss and mentor of Phoenix Wright at the law firm Fey and Co. Law Offices. Her background is rooted in the Kurain School of spirit channeling, a tradition passed down through her family; she is the older sister of Maya Fey and the daughter of Misty Fey, the former master of the Kurain technique. Mia's personality is characterized by cleverness, quick thinking, and a calm, focused demeanor in the courtroom. She is known for her determination and willingness to use bluffing tactics to uncover the truth and protect her clients. Her primary motivation is a deep commitment to justice and a steadfast belief in her clients' innocence. After she is murdered early in the story, Mia continues to play a vital role as a guiding presence, being channeled through her sister Maya and later their cousin Pearl Fey. In this spirit form, she offers crucial advice and insights that help Phoenix during difficult trials. Her key relationships include her mentorship of Phoenix Wright, her protective bond with her sister Maya, and a past romantic connection with Diego Armando, also known as Godot. Mia's own backstory is explored through flashbacks, revealing her first case as a defense attorney and her previous encounter with the antagonist Dahlia Hawthorne. Her notable abilities include sharp legal reasoning, strong courtroom presence, and the unique capacity to be summoned as a spirit to assist in investigations and trials from beyond death.
