I read volume 8.
It was good because there were a lot of conversations of Horo and Lawrence though there was no dramatic development.
Horo who suffers from muscular pain was amusing.
Before, I read something as the author's talk, this series probably will be completed by about ten volumes (I think that they were 13 or 16 volumes).
They are already near the Yoitsu. But it is likely to take time before arriving there.
If my impression from volume 1 to volume 9 is shown by the key word, it is as follows.
Vol.I "Encounter" : Loneliness, Apple, Horo's transformation
Vol.Ⅱ "Nora": Bankruptcy, smuggling, and jealousy
The following is a spoiler.
