Actually there is a live action movie for this manga found this news from this page http://asianwiki.com/Pink_and_Gray. And it seems ganool already have this movie
This chapters really feel like last chapters wwwww
Well, we still don't know what is this book the Guild wanted ( and i'm sure they will come back ), and why Atsushi is supposed to know the book, and of course I'm still waiting to see the mafia's boss doing...anything, but just to see him in action XD
So I would say the manga isn't really close to a end ╮( ̄▽ ̄)╭
IT NEEDS MORE CHAPTER!!!
