I really enjoy Tomo-chan, partly due to the short chapters and frequent releases. When it's publishing, I look forward to the chapter and it's easy to fit in the time to read it because takes like 10 seconds to read.
Tomo-chan is a very light-hearted read. Plot happens at a very slow-pace (and very little has actually taken place, but it might just feel that way because there seems to be so many chapters when in actuality it's only a volume of content), but for me this manga is more about just enjoying what does happen: the comedy, characters, friendships, silliness, ect. It's a comedy at it's core and everything else, the romance and plot, are secondary.
The characters are all likeable. Tomo is adorable, tough, tomboyish, and in love with her best friend Jun. Jun is dense (though not as much as he may appear to be), strong, and cherishes his friendship with Tomo. Tomo's friends are all given ample screen time for readers to fall in love with them as well, and the female friendships that exists are interesting to explore and read about. Sometimes you'll get frustrated with Jun if you're heavily invested in the romance, but after a while you learn not to expect much in that department and just enjoy the cuteness and hilarity.
The art is surprisingly well-done for one page a day. It's gotten much better in the past couple of chapters that I've actually paused to admire it on the occasion. And since I first wrote this review, it's gotten better and better!
If you're looking for a funny comedy and an overall enjoyable read, I would try this out, but remember that the romance tag isn't the focus so don't expect too much on that front.
