Abe (Takayuki Yamada) is a freshman student at Kyoto University, currently suffering from the springtime blues. He ends up accepting an membership party invitation from the one of the Universities activity clubs, the Azure Dragons ('a perfectly ordinary club'), mostly from boredom and the offer of free food and booze. He joins the club because the beauty he is smitten with joins. Friendships are tested, hearts broken and I can say no more.
This movie is best seen cold with as little foreknowledge as possible, so no spoilers because it really would spoil the movie. KAMOGAWA HORUMO plays like a coming of age at University romanctic comedy all while the weirdness slowly jacks up. Yes, there's a clue in the title, but whatever you're thinking, that's probably not it. Though, yes, there are punches thrown. It's funny, a little silly and you get to see a lot of Kyoto and assuming they shot on location, Kyoto University.
