Review of Black Butler: Book of Circus

This is by far my favorite season/arc/etc of Black Butler. The story? Hilarious. Watching Sebastian be his perfect self while Ciel nearly dies from doing the bare minimum is incredible. The characters? I love them. A lot of new characters are brought into this arc and the fact that time is given to develop them and give them each distinct personalities is really great (Doll is my favorite and SHE DESERVED BETTER). The ending? My jaw was on the floor. I won't spoil anything but I really loved how much they dived into Ciel's backstory. A lot of questions were answered (Not all!) and youreally got to see Ciel as scared little kid he tries so hard to hide. I could watch this arc over and over again and still be on the edge of my seat the whole time. If you were disappointed in the show for going so off canon, this is what you're looking for. It goes back to the manga and stays pretty true to it. It's a great time, trust me.
Also the theme song "Enamel" the absolute bop of the century, I listen to that song AT LEAST once a day.
