They say the more things change, the more they stay the same, and this holds especially true for Ousai Private Academy's student council. Despite a full year passing and the senior members entering their final year of high school, little has altered. President Shino Amakusa remains as lecherous as ever, Secretary Aria Shichijou still refuses to wear underwear, Treasurer Suzu Hagimura hasn't grown an inch, and Vice President Takatoshi Tsuda continues to serve as the straight man to their wild antics.
Of course, limiting the fun to just the four of them might grow stale; though the group still messes around with the Judo Club and Newspaper Club, more girls have joined in on the excitement. Takatoshi's sister Kotomi, a new student at Ousai, is as depraved as the president, while Uomi, the aloof student council president from nearby Eiryou High School, fits right into Ousai's insanity. With endless absurdity and sexual humor that keeps coming, Takatoshi needs to toughen up if he hopes to keep up with all the madness surrounding him.
