Horrible last chapter... if it wasn't for School Rumble Z this would have been the worst ending of manga i have ever seen, only a few funny stuff and nothing happened =/
Anyway, I heard School Rumble Z could may be only a few chapters, but at the last page of this chap it says: "School Rumble Z will start in... bla bla bla" so to me, seems like it will be something long... hope I'm right :P
