Limbo is a manga that deals with being different and being lonely. The main character Fuu and the people she meets all have something different about them that makes different from the people around them, whether it be their ears, voice, size, or strength. These differences cause problems, both because of active discrimination and because some of the characters are insecure about themselves. Stories tackling these kinds of topics can be difficult to pull off, especially in a 4-koma comedy where most of the chapters are only 8 pages. The degree to which it succeeds can be debated, but the result is amostly cute story that does at least try in its own way to talk about accepting people's differences.

The story mainly revolves around Fuu, but there are several side characters. Most of these characters are not very well developed as the story doesn't spend much time on characterizing them. There were a number of instances where I was disappointed that we didn't get to learn more about a character or a situation.

The art quality is good enough. It's not spectacular but neither is it bad.
