Just as delightful as Vol. 1, for a certain robust value of delightful. This volume continues and concludes the spinoff mini-series, apparently.
Recommended, but it may be better to start with the parent series, Cells at Work!, for context and continuity. (This will not be a suffering.) The anime (which is very fine) and the manga are almost interchangeable, but the manga has a few chapters that didn't make it into the anime, and unlike the anime the informational boxes sit still long enough for one to read them.
Have read this manga pair twice since I bought them, fwiw. I keep showing the original anime to friends, so I've ended up watching it multiple times. Not bored yet. Still laughing. So much meta...

Later: ha, it appears 2 more volumes of this are in the pipeline. As soon as they appear in a Kindle edition, I will snatch them up.
