~Spoiler Free~
Me giving all 10s to the categories of Natsume Yuujinchou may seem excessive but it is exactly how good I think that this anime was (it's my all time favorite). I think that this is a good anime to watch when you don't want to overthink too much about a plot. It's truly relaxing to watch.
Story: the plot isn't too complicated and easy to follow and at the same time is very entertaining.
Art: the colors in this anime are somehow calming and beautiful as well as aesthetically pleasing. The overall animation is also something that I think the creators did a great job on. It doesn't feel The art is definitely one of the things that made me completely fall in love with this anime.
Sound: like with the art, the OST is also very calming throughout the anime (most of the time). As for the OPs and EDs all throughout the series, they're those ones that you can't bring yourself to skip.
Character: I instantly related to and completely fell in love with all of the characters in the series. They're all so precious that it's hard not to.
