It's going to be a collection of short stories for Volume 15, but it seems like the last story isnt going to be a short-story but the past of Kiba. Kiba goes off to Romania with Rias and Azazel in Volume 14. So he's probably going to have flashback or something to explain his past. Author did say that Volume 15 will be special so its going to be a semi-main story volume with short stories.


 * I'm guessing this was said in the Afterword of Volume 14, and that it may incorporate more canon material than the past Short Story Compilations (i.e. Volume 8 and 13), with the exception being the Extra Life. Granted that parts of some short stories are mentioned and referenced in the main story, but I'm guessing that this new Volume 15, "The Dark Knight of Sunshine" will do much more than that.
