Black Butler is a good anime, but just because I think the anime is good doesn't mean you'll like it. In summary, the anime is about a boy named Ciel and his butler Sebastian. Ciel's parents died in a fire, and he contacted Sebastian to avenge his parent's death. As you can tell, this is a dark anime, there's death, fight scenes, and this shouldn't be taken lightly. Some people say the manga is better, others like the anime, and there's people who like both. I personally never read the manga, but the anime is good, not one of my favorites but the plot is just amazing.
I recommend Black Butler, that is if it's you're kind of anime.
