Ranko Hata is a Second Year (later Third Year) student at Ousai Academy and the Head of the Ousai Academy Newspaper Club. She is notable for several reasons, among them the fact she is drawn slightly differently from other characters (most obviously her lack of a nose) and the fact she makes the most appearances outside of the Student Council members. Ranko has a quiet, deadpan personality. Her expression is generally neutral, though she occasionally smirks when something interesting happens she can use in her newspaper. She takes her position as Head of the Newspaper Club seriously and is almost never seen without her camera. A true professional journalist, she claims her camera is as vital as part of her body. One of Hata's defining character traits is her complete lack of morals when it comes to getting scoops. While she will not outright make things up, she has no problems tweaking information or pictures to make a story more 'interesting'. There is also a suggestion she won't hesitate to sell pictures of people to interested parties. Ranko also occasionally causes trouble for no other reason than she thinks it would be funny (or lead to a scoop). More commonly, she'll deliberately mishear what someone tells her to make it sound perverted. Her most common target is Takatoshi, though Shino and Kaede are also common targets.

On his first day of high school at the formerly all-girl's Ousai Private Academy, Takatoshi Tsuda is called out for his untidy uniform by the student council president Shino Amakusa. In apology for delaying Takatoshi for his first class—and stating that the group needs a male point of view to accommodate the arrival of boys at the school—Shino offers him the position of vice president of the student council. Though unwilling, Takatoshi finds himself appointed as the newest member of the student council having yet to even step foot inside the school building. Takatoshi soon realizes that the other student council members who are more than a little strange: President Shino, who is studious and serious in appearance, but actually a huge pervert, fascinated with the erotic and constantly making lewd jokes; the secretary Aria Shichijou, who may seem like a typical sheltered rich girl, but is just as risque as the president, if not more so; and finally, the treasurer Suzu Hagimura, who may act fairly normal, but has the body of an elementary school student and is extremely self-conscious of it. Surrounded by these colorful characters, the new vice president must now work through a nonstop assault of sexual humor and insanity.
