Profile
Aqua was a princess of the Nohrian royal family, but was captured and held prisoner by Hoshido in a similar fashion to the Avatar. Aqua is a gifted songstress and dancer and is seen dancing in a theatre, watched by Garon. The song she sings is if~hitori omou (if一人思う lit. if~one's thoughts). Aqua's singing holds great, but mysterious powers.

Shortly before the start of the great war, Aqua meets the Avatar and they discover their similar origins and situations. Aqua allies with the Avatar through the story of if, regardless of what route they choose. In the Hoshido route, Aqua wears a white and blue dress. In the Nohr route, Aqua wears a dark blue and purple dress as well as a veil. It is currently unknown if she will wear a different dress or one of the other 2 if the third path is chosen.

Etymology
Aqua is the latin word for water. It is also a greenish-blue color.

Trivia

 * Aqua has two different in-game voice actresses (not including language changes : her in-game voice actress is Lynn while her singing voice is provided by Renka. This has already been seen in the Fire Emblem series when other characters had to sing (like Ashunera and Sephiran in Radiant Dawn and possibly Micaiah).
