In Path of Radiance, Mia is a mercenary hired by Crimea, and is captured by Daein soldiers. As a result of being set free by Greil, she joins his mercenary band to pay off her debt, but remained with the mercenaries. Mia's training tends to be rather extreme, with her attempts to spar with others being rather aggressive in nature, whereupon she convinces Rhys to stand by the side in order to heal any wounds she may receive. She is most likely Ike's preferred sparring partner, as she tends to not complain about the fact that he never holds back during their training sessions, even seeming to enjoy them. After the defeat of Ashera, Mia sets off on a journey around Tellius in search of new opponents, occasionally stopping by Greil's retreat to rest.
