Ya... the last battle with Kawahira and then just ended all too peacefully.. She should make it they beat a crap of Kawahira, or at least some fights between Tsuna and Kawahira before he revealed himself and they talked about it.
Well, I guess the author has no more ideas of new enemy or threat to come up with. I'm glad that she ended it now, before she actually decided to bring alliens/outerspace threats into the story lol (which I doubt she will)
Hmm, now that everything ended, I kinda want to watch the anime again, especially Future arc.
