The only thing that disappointed me was the ending. But maybe because I'm being sentimental or I just wanted to see more of Sebastian! (reason I made it a 9 :L)
Sebastian is a perfect butler. He arrives just in the nick of time! He's brilliant at him job but inside he's something out of this world (such a cliche choice of words, I know!).
I enjoyed this anime a lot. At times it had me clinging to my desk or (ironically) praying for a good turn out.
I LOVED the characters. Meirin, Finny, Bard, Tanaka, Pluto, Ceil, Sebastian, Greil (Grell) etc. I loved Grell a lot, he was hilarious. Tanaka was an interesting character. Meirin was a sweet character but had a dark side (as did most of the characters). Finny I loved because of his cute nature and yet he was so strong! Bard was hilarious and his love for blowing up the kitchen with dynamite! Ceil I also loved because no matter how ignorant and evil he seemed he still cared for people and I think Sebastian is very similar to Ceil.
I loved all the different stories which in the end all linked into this one large, hard-hitting ending! It was very interesting!
Overall a well deserved 9! And I strongly recommend it!
