Mia

Ike: I'm counting on you, don't let me down! ''Mia: Never! I wouldn't know how!''

Mia (ワユ, Wayu) is the newest member of the Greil Mercenaries. In Fire Emblem: Path of Radiance, she was captured by Daein soldiers, but was released by Greil. She returned to pay her debt, but remained with the mercenaries, claiming to have "fallen in love" with Ike's swordsmanship. She learned some of her sword fighting skills from Ike. Her training tends to be aggressive, and when she attempts to spar with Ike, she convinces Rhys to stand by in order to heal any wounds she may receive. She is most likely Ike's preferred sparring partner as unlike Mist or Titania, she does not complain about the fact that Ike never holds back, she seems to even enjoy it. After Ashera's defeat, Mia set's off in search of new opponents. She traveled all of Tellius, but sometimes went to Greil's retreat to rest.

Personality
Mia can be easily described as eccentric and upbeat. In her supports she will often run around and challenge the first person she sees to a duel. After hearing a fortune-teller say that "your archrival rides toward you in white robes" she took this to mean that Rhys would someday gain power to rival her own despite the fact that Rhys starts out as a priest and therefore cannot fight. Despite her eccentricities however, she is a genuinely nice girl, as shown during one of her training sessions with Rhys, in which she forbids him to practice with swords anymore because it was making him sick.

Trivia
In Fire Emblem: The Sacred Stones, Forde mentions that Kyle has a sister named Mia in their B support, however neither character's name was Mia in the Japanese versions.

Mia, along with most of the Greil Mercenaries (save Rhys, Oscar, Soren, and Gatrie) was given a voice in a cutscene in Radiant Dawn. However, there are no credits given to voice actors in that game, so their actors are unknown.

Fanfics about Mia are highly popular towards Rhys and Soren. This is because she shows a tenderness towards Rhys, and Soren makes comments about how she can't die in his support conversations in Radiant Dawn. However, Rhys is a priest bound to clergy, and Soren's conversations are default.
