Ooarai Girls High School is a school originating from Ooarai Town, Ibaraki Prefecture, Japan. The school is far smaller than other schools shown in the anime, and has lately been losing students. Ooarai's only notable feature, it's Sensha-dō club, was suspended many years ago for unknown reasons. Until the club's revival in the events of the anime series, the school had no overall focus and lacked any outstanding features. This, in addition to the fact that the school has been accumulating deficit for several years, places it at risk of closure at the hands of the Ministry of Education.
