Aria volume 1

the long version

On the planet Aqua, a world once known as Mars, Akari Mizunashi has just made her home in the town of Neo-Venezia, a futuristic imitation of the ancient city of Venice. The technology of "Man Home" (formerly Earth) has not entirely reached this planet, and Akari is alone, having no contact with family or friends. Nonetheless, the town, with its charming labyrinths of rivers and canals, becomes Akari's new infatuation, along with the dream of becoming a full-fledged gondolier. Reverting to a more "primitive" lifestyle and pursuing a new trade, Akari becomes both adventurous and independent all at once.
