Black Butler is one of my favorite anime. It deserves a 10/10. Everything was outstanding, the story, art, music, and everything. I really enjoyed it. I could re-watch it again and again. The anime was really exciting. Here are somethings that stand out:
~12 year old kid with a awesome demon.
~awesome music
~Crazy grim reapers
~a evil ANGEL?!?!
~ETC-
Like who can hate this anime?? So i'd recommend you to watch it.
