Drift into Neo Venezia, a metropolis on the planet Aqua, in peace (formerly known as Mars). Humans have discovered a means to settle the formerly uninhabitable planet by the 24th century. Neo Venezia is still overflowing with rustic beauty, with gondolas plying broad canals and rivers as the primary source of transit. The city itself is an exact duplicate of Manhome's (the planet that was once known as Earth) Venice. Companies offering guided gondola tours, such as Aria Company, were founded to ensure that inhabitants and tourists alike got the most out of Neo Venezia's many charms. Akari Mizunashi, a free-spirited adolescent from Manhome who is now a novice Undine, works here.
