Black Butler II.

Hated by many, but loved by me.

Except the ending.

The ending was horrible (imo don't kill me)

And it's aaaall because of one thing.

CIEL IS A DEMON.
The anime has no correlation to the manga, (I think, hopefully I'm correct) and I'm happy about that, because at least this stupid decision wasn't made in the manga.

Ciel was amazing as a human being. But now he's a demon.

Now, I watched Book of Circus before II, (and I am so happy I made that decision because if I had watched them in order I never would've been blessed with the gift that is Book of Circus)
Luckily, Ciel is not a demon in Book of Circus. But I wouldn't have known that, because I am still a noob on the concept of Black Butler even though I've finished the series. (Except for Book of Murder, but I pretty much already know what happens there.)

The thought of Ciel now being a demon, and for Sebastian to now miserably deal with his crap for all eternity is just

NO!!!!

k thx bye
