Wrote a review on this, here it is:

Technically, it's "just" a review for "the first series", but it applies to "both" of course since this series ran into some trouble and just ended up continuing again with a barely different title. I like this series a lot, and I wanted to write about it at length, so I did. I hope it can convince some that Chimoguri is worth a read.
The ending is sadly weak, but the journey is mostly fantastic.
