Ciel Phantomhive is now the head of the Phantomhive corporation, handling all business affairs as well as the underground work for the Queen of England. His new partner is a demon butler, Sebastian Michaelis, whose powers as a butler is only surpassed by his strength as a demon.

My Review: Totally did not know the rating when I first watched this XD I was like the same age as Ciel when I watched it. So like if you don't like perverted jokes or violence I suggest not watching this. Ciel does underground work for the Queen so he does show up at a few murder scenes. Overall plot is quite interesting. If you like mystery then this is definitely one for you. It's a nice balance between comedy and angst in all honesty. Plus the butler is yum~ Like who wouldn't want someone like Sebastian~
