Seitokai Yakuindomo Episode 5

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.
