Tough to compare to anything else. It's a "healing" series about some girls learning to be gondola tour guides on a replica Venice recreated on Mars after it's been terraformed. Setting is an idyllic utopia and the girls are pretty. That's it.
One part school slice-of-life, maybe, without the high school, and one part landscape/replica architecture/cloud porn.
Best compared to the manga Yokohama Kaidashi Kikou (minus the apocalyptic theme), with stuff like Sketchbook or Marimite coming up at a distance.>>11334714
Oh, I like that comparison.
