There is a nice review of this series on Mangaupdates, I'll paste it here for reference
"I really enjoyed the first series. I've always loved the darker side of fairy tales and legends,
and Munakata really strikes a good balance between intellectual and horrific.
(Of course, I don't think that most of Munakata's theories are always the best interpretations
of legends, but they are really interesting.)
This second series is much like the first, but the stories are a bit more interconnected.
The side characters, particularly the female ones like Imibe, Isabella (the English witch)
and Taki (Munakata's niece), are given more development and appear in multiple stories.
It's also a nice break from Munakata saving the day every time to have other characters help him.
There's also more of a focus on his past (I hope we'll eventually see more about his family as well
in the remaining volumes) and on his research of legends relating to iron metalworking
in ancient times.
The legends in this one are just as interesting, which is surprising because I almost felt as though
Hoshino had exhausted every legend that could possibly relate to Japan.
I'm glad that this isn't the case. I'd gladly read a third or fourth Munakata series."
