On his first day at a new school, Takatoshi is coerced into becoming student vice-President. Since the school is almost all girls, they often seem to forget he's a boy and talk about disconcerting girl problems when he's around.
The student council investigates the legend of the school's ghost. They think it's fiction - until they hear eerie cries coming from the English resource room.
The school's first co-ed sports festival is being planned. The girls of the student council lose all inhibitions when suggesting what new events should be in it.
Takatoshi's sister starts attending his high school. He attempts to shield her from the blatant anatomical chatter, but usually fails. She doesn't mind.
