What just happened? Is that the end?? If yes then its even bad end than the previous end...this ending left so many questions unanswered
No, not end yet. Just the prologue. There will be more. Probably a prologue of yet another arc. Let's wait for the author's note, he/she might reveal how long do we have to wait for another volume or will it be the end already.
