Funimation has Black Butler: Book of the Atlantic
I was so worried it was going to go to Aniplex.
Usually when a company draws up a contract for a show, they'll put in a "Right of First Refusal" for any subsequent seasons / movies etc for a show. This way they get the "first look" at new seasons movies etc.
That way they are guaranteed a shows sequels and spinoffs, and if a show does poorly, they can pass on a new season (like they did with Fafner)
I had been hopeful that they would get it, and thought odds were pretty good considering they have gotten all of the series up to this point, but I wasn't sure if things would change considering how much everything with Aniplex shows has changed in the past year or so, and especially with Funimation losing the license to Black Butler.
