Head of her own criminal defense law firm, Mia Fey is Phoenix's boss
Personality: Always cool under pressure, Mia Fey is smart,
tenacious, a strict teacher and sometimes even coy. She has a great
affection for her sister but is also very independent, and strives to
uncover truth at all costs.
Mia Fey left her home in Kurain, several years after her mother's sudden disappearance. She wanted know the truth of what had happened in that fateful DL-6 case (and also didn't want to have to fight her sister for leadership of their clan, as family rivalry continued far back into Kurain's history). She joined a law firm under Mr. Grossberg, along with Diego Armando.
Her first case, State vs Fawles, ended prematurely when the defendant died as a result of poison. The young woman responsible for the poisoning (not to mention several other crimes) escaped judgment due to lack of evidence. That woman was Dahlia.
Sometime after this case, Mia started seeing Diego, though it's unclear exactly how far their relationship extended. However, six months after Terry's case, Diego was poisoned while attempting to question Dahlia and passed away. Determined to get Dahlia behind bars, Mia continued her law studies and finally had the chance to convict Dahlia of murder in the case of State vs Wright.
It is presumably after this case that Phoenix intensified his studies of the law and eventually joined Mia's law firm.
