Fumizuki Academy is holding an exhibition at Ouran Academy to show off the Summoner Test system. The Ouran students get a crash-course in academic dueling, and Fumizuki gets a crash-course on the most popular boys in school. Things get complicated when Kyouya decides to make a bet of it. Why do the Hitachiin twins keep calling Hideyoshi "Baby"? Why is Pome, Mori's raccoon, in a sweater? Why does Kasanoda need a bit of a lie-down? Does Kyouya ever make a bet he isn't sure he'll win?
