I just finished an Anime series I've been watching for the past few weeks, It's called Kuroshitsuji
It's a lovely,dark story with its odd moments of humor, and set in 19th Century England. It has this odd, bittersweet tang to it, and the relationship between Ciel and his (demon) Butler Sebestian is something so profound and oddly sweet, despite how dark it truly is. The art is gorgeous as well, obviously as you can see from above. I am a sucker for "Period Dramas" for the clothing, so this no exception, and only one of the reasons why I adore the series.
It was sad to finally finish it, but I always get melancholy when I finish a series. I have the manga to read, so I am going to start on that. =]
