Mia Fey runs her own criminal defense law firm and serves as Phoenix's boss and mentor. She's known for staying calm under pressure, sharp legal instincts, and a no-nonsense teaching style—though she can be surprisingly playful when she wants to be. Above all, she's driven to uncover the truth, no matter what it takes.
She's close with her younger sister Maya, though she's fiercely independent otherwise. Her mother Misty disappeared 15 years ago, and she has an aunt Morgan and cousin Pearl on her side of the family. She's also in a relationship with Diego Armando, her former mentor in law who began dating her a few weeks after the traumatic Terry Fawles case. How serious things got between them remains unclear, but their feelings for each other are unmistakable.
One quirk: she has a habit of mishearing people's names, usually calling Phoenix "Naruhodo" and referring to things as "Yappari" when they're not quite right.
Interestingly, the writers originally planned for Turnabout Sisters to be Phoenix's first case, but scrapped that idea so Mia could mentor him more before that case unfolded.
Name Origin
English: "Fey" likely references magic and spiritualism (think Morgan le Fey), while "Mia" pairs naturally with "Maya."
Japanese: Creator Shu Takumi describes "Chihiro" as a pun—the kanji together mean "1000 questions," as in I'll ask him 1000 times if I have to. The second kanji also appears in the word for cross-examination.
