Have always loved Kuroshitsuji, and the number of plot twists in the Book of Circus just seriously flipped me. I couldve never expected these unexpected turn of events, which makes the plot so much more interesting. Alot of thought has been put into each character - you can tell by the backstory and how they each react differently to the same events. Loved this, I can't wait for another to come out (I heard that Book of Murder may by coming out in October).
