Simply the GOAT i LOVED it it is a short manga but a very good one IT IS DIFFERENT FROM THE ANIME (the anime is good but i prefer the manga, not by a lot tho) Story: A story about a man that cleans trash? it cant be that good yes it can, and it is Everyone who likes space or sci fi things should read itArt style:
The art style is awesome, beautiful.

Characters:
the characters are unique and they complement each other
they are really human, the story itself is human and talks about humanity's egoism

Opinion:
Makoto is the GOAT, and this manga is simply his best work, really really underrated
Vinland saga is good BUT this is even better!
The way it talks about Love, Death, Life and dad to son interaction is simply incredible
