Seriously, c'mon people. These are magazine chapter scans, so of course they're going to push the tankobon volume release at the end, which obviously had not been released at the time the chapter was released. It's kind of hard to release the collection of all chapters in a volume before all the chapters have been released to compile. This is the end of the story whether you like/believe it or not, though the tankobon might end up having some omake or extra content when it gets released.
