Aria: The Natural: Tooi Yume no Mirage

Aqua and Aria’s events occur in the early 24th century, beginning in the year 2301 AD, in the city of Neo-Venezia on the planet Aqua. Aqua was formerly known as Mars; however, it was renamed Aqua after it was terraformed into a habitable planet covered in oceans approximately 150 years earlier. Neo-Venezia, modeled after Venice in terms of its architecture and atmosphere, is a port city with winding canals instead of streets, and non-motorized gondolas are used for transportation.
