I'm a librarian who loves anime, manga, and reading a wide variety of genres.
This volume is incredibly tragic. Joker, Beast, everyone. The flashback to their early days, the revelation that the Baron hadn't fulfilled his promise and cared for their friends back at the workhouse. Even though the Baron could be almost laughable at times, he really was a nasty piece of work. The volume's ending was almost over-the-top light, fluffy and humorous, but necessarily so, in order to help readers wind down after all the prior darkness.
I really wish Ciel had refrained from killing at least a few people. Although I suppose they'd have been his future enemies then, always seeking vengeance for the ones he didn't spare. I was shocked at how totally Ciel had Sebastian destroy the Baron's place and his work.
Inside back cover extra: Black Track.
