Mary Catelli's Reviews > Aria: The Masterpiece, Volume 1

In the future, when Earth is Manhome, and Mars is a terraformed world called Aqua because the melting of the icecaps flooded it more than originally intended -- Akari leaves Manhome for Aqua, in order to fulfill her dream of being an undine -- a gondolier.

She has an apprenticeship, and during the long Martian summer, she learns why undine companies have intelligent Martian cats as presidents, buys a special wind chime and learns of their secrets, survives the annual high water and rain (though tides strike me as improbably -- it doesn't mention the two moons have been replaced), befriends another apprentice, is put to a test, and more.
