Wayu (Fire Emblem) Fire Emblem: Path of Radiance Images

Mia (ワユ, Wayu in the Japanese version) is the newest member of the Greil Mercenaries. In Fire Emblem: Path of Radiance, she was a mercenary hired by Crimea, then captured by Daein soldiers, but was released by Greil. She returned to pay her debt, but remained with the mercenaries. She also 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.

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.

As revealed by her support conversations with Largo, Mia is also very rebellious against the traditional idea of a woman being unable to fight. Resenting the stereotype that "A sword doesn't belong in the hands of a woman", Mia is very quick to accuse male opponents of going easy on her or assuming that her prowess as a swordswoman is inferior just because she's a woman.
