It Will have nothing to do with the anime (which will get a second season).
This Sunday it has been reveales that the Franchise Kantai Collection will get an Animated Movie.
Also they said that the second season of the anime will come in 2016, probably January.
The staff stated that the anime and the Movie will be separated and will be two projects handled at the same time.
I Didn´t liked the anime, but is nice to know that the fans of this Free to Play game will get to see more of their ship Girls (Pun totally intended) in Anime form.
