アリア [Aria]

Set in a terraformed, Venice-inspired Mars, Aria is a gentle, slice-of-life manga about a young woman training to become a gondolier—a "Undine"—who guides tourists through the city’s tranquil canals. Created, written, and illustrated by Kozue Amano, the series ran for 12 issues from 2002 to 2008, published by Mag Garden. Its quiet, meditative tone and lush, watercolor-style art made it a standout in the early 2000s, defining a subgenre of "healing" manga that prioritizes atmosphere and small, human moments over dramatic plot.
