Seriously, Kuroshitsuji, season 2.
I'm ready to tip my coffin off anytime now.
It's according to AnimeNewsNetwork [link] The news even listed in Wikipedia O_O; There's an entry relating to it in the official site [link]
I found out about this when I read the latest scanlation chapter in Onemanga.

Now I wonder how the story will turn out.. *thinks*
I found some speculations that Sebastian will be a butler to someone else, say, his other client/prey, or Ciel isn't actually devoured by Sebastian, or what actually happens to them after the damn black screen with 'Now, young master.' spoken with it.

I'm so going to size down and cosplay Sebastian srsly..
