Ranko Hata is the head of the school's newspaper club. She likes to take photos of the student council members to sell around the school, usually without the permission of those being photographed, and she often gets caught. When she conducts an interview, she likes to twist the responses to something dirty or perverted, with Tsuda as a frequent target; running gags in the series have her constantly trying to get Shino and Takatoshi to admit that they are dating, or her admitting to spreading rumors about it, much to their chagrin. She is expressionless most of the time (but has been shown to smile on infrequent occasions) and has a deadpan monotone voice in the anime, which strongly contrasts with the other girls' excitable temperaments. She is also the only character who breaks from standard movement conventions, namely sliding across floors, phasing through doors, etc. She has a habit of saying "kodak" whenever she is about to take a photo of someone and in one of the episodes every time she took pictures Aria and Shino would erase it afterward.

Tsuda Takatoshi is about to begin his first year in Ousai Academy. His decision to enter Ousai was based upon it being close to his home and he paid no heed to the fact he'd be among the first boys to enter the recently gender-integrated school. 
On his first trip to school, Takatoshi is surrounded by girls; the train has nothing but girls, the walk to school has nothing but girls and once he finally arrives he is approached by a group of girls and summarily appointed vice-president of the student council and, as expected, he is the only boy there. 
Now Takatoshi finds himself surrounded by crazy girls who do nothing but horrify him with their candid conversations about feminine hygiene products and, what's worse, assume he's the worst kind of man, the kind who doesn't clean himself and watches porn all day long.

The work of Ousai Private Academy's student council is never done. This time, Takatoshi, Shino, Aria and Suzu are back with their very own movie! From TV interviews to a new teacher, there's even more potential for misunderstandings as the double entendres, innuendos and euphemisms reach critical mass.

The cast is back and ready to quip! In this companion film that follows season 2 of the zany, irreverent Seitokai Yakuindomo anime series, the student council must again grapple with a mix of double-entendres and doubly potent teen hormones.
