This is basically a “fluff” volume, although it's not bad – a nice transition from the recent threat to Shurei's dreams to Shurei and Eigetsu beginning their time as joint governors of Sa Province.
The stuff with Ryuren was mostly silly. I don't know that I like him much, but Yukino's attempts to paint him as more than just “that irresponsible weirdo” were interesting. The stuff with Reishin's Shoka masks was just...creepy. I get that Reishin loves his brother, but he needs to scale it back some.
My favorite part of the volume was probably the flashback at the beginning. I enjoyed getting to see young Shoka, who apparently has had to do and see horrible things from a very young age. As creepy as Reishin can sometimes be, I found it kind of touching that he still adores and supports his older brother, even knowing what Shoka has had to do in order to protect the family.
