Mitsu Tsubo is a short manga series by Moriya Makoto (rest in peace). It features some really stellar artwork and I enjoyed it immensely.
Each chapter has a slightly different story but most involve scenarios with a younger male protagonist and one or several older women. The story is pretty limp and probably the weakest part of this manga. I didn't personally mind this, since the manga makes up for it in other departments, but it's something to be mentioned.
The art is easily the best aspect of this manga. All the characters have a style unique to the artist, they're all
very detailed and it all works really well. If I do have one critique, it would be that everything starts to look really similar as the manga goes on. Now again, I personally didn't mind since I really like the art, but I do wish there was a little more variety.
The characters are nothing special. They don't get much development since each chapter is a different story complete with different characters. However, I think their character traits were still effectively conveyed. They mostly fall into several archetypes like mothers, teachers, sports players, bullies, etc.
Despite a few shortcomings this manga is still really good. I just have an easier time criticising things than praising them. There's just something about this manga that works. The way the art mixes together to create some really amazing scenes that feel like they have motion. 8/10
Overall I really enjoyed this manga and I'd highly recommend you read it.
