Saturn Apartments is a strange mix of hard sci-fi, childlike art and sentimentality. Mitsu is a window washer on a space station orbiting an abandoned earth. Life on the station is highly stratified: the rich get windows and natural sunlight while the poor live within the station’s core. This volume sets up some interesting dichotomies between haves and have-nots and corporations versus individuals, but these themes take a back seat to the stories of the people Mitsu meets on the job. While the stories are sweet, it’s the science and structure behind Mitsu’s world that make this manga truly interesting.
