St. Lobelia Girl's Academy's Benio Amakusa, head of the Zuka Club, chances upon Haruhi and, instantly recognizing that she is a girl, tries to convince her to join her school and her club. Convinced that Haruhi will leave them, the boys dress up as girls to show Haruhi that she "can have big brothers AND big sisters - all in one!" Haruhi reveals that she came to Ouran for a reason, and says that she was never planning to leave for Lobelia in the first place.
