Chio-chan is a great read that makes me laugh hard every few pages. The stories are mostly about Chio-chan going (walking / running / parkouring) to school, but the setting doesn't really feel like that usual high-schooly thing. There are rarely any pages where the characters are actually in school. Sometimes the humour comes from strange situations the characters get into, sometimes it's the conversations they are having, but it's usually great. Its nature is intelligent, and often a bit absurd, but nothing close to Excel Saga, for example. Sometimes you also get ... lewd vibes from some pages, but it's not the point of the manga, andit's done in a tasteful way.

I can't wait to see the anime version. Hopefully it will bring attention to this great manga, which you should read, if you like the pure comedy genre.
