Despite a full year passing and the senior members now in their final year of high school, the Ousai Private Academy's student council remains unchanged. President Shino Amakusa continues to be as perverted as ever, Secretary Aria Shichijou still refuses to wear underwear, Treasurer Suzu Hagimura hasn't grown a bit, and Vice President Takatoshi Tsuda still manages to play the straight man amidst their crazy behavior. However, to spice things up, they've incorporated the Judo and Newspaper Clubs into their escapades, and new girls are joining in. Takatoshi's sister Kotomi rivals the president's lewdness, while Uomi, the stoic student council president from Eiryou High School, fits right in with the madness. With plenty of odd and titillating jokes, Takatoshi must toughen up if he wants to keep up with all the madness happening around him.
