They use a lot more cultural language here with some more specific talk about animals etc. This is definitely harder than volumes 1 & 2, I struggled a lot with this whereas I didn't with volume 2 for example :)
Still fantastic, just watch out if you're a language learner!
Easier than previous manga volumes in this series
The first manga volume has 6k chars, it averages around this for a bit.
This volume (v4) has just over 3k, and that's including the cover page etc.
I was averaging 2 - 3 hours per volume of the previous ones, but this one I did in just 64 minutes over my lunch break.
