While not (usually) enforced, there is a recommended hairstyle of short hair dyed black. The standard Oarai uniform consists of a white serafuku with a green trim, a matching green skirt, and a black neckerchief. It also became an inspiration for many other schools across the nation, creating a surge in senshado activity amongst minor schools, the result of which has dramatically elevated Oarai's status within the MEXT department. Throughout the 63rd National High School Senshado Tournament, the school developed close friendships with the other major senshado schools competing in the tournament.

Despite its initial infamy, Oarai Girls' Academy soon gained popular attention as its assorted collection of tanks defeated multiple senshado powerhouses, including the defending champions, claiming the championship despite having fought every match at a numerical disadvantage with substandard equipment and inexperienced crews. Its newly revived senshado club entered the tournament under the command of Miho Nishizumi, a former Kuromorimine student and the central figure in a controversial incident in the previous year's tournament. The school received high publicity in the year of the 63rd National High School Sensha-dō Tournament. Other clubs, such as the volleyball club, have also been recently disbanded as necessitated by budgetary constraints. The school's history of senshado has faded into distant memory, to the point that few records remain of their exploits. Its senshado team had been disbanded long ago but was revived by Anzu Kadotani in a bid to avert the school's closure.

Oarai Girls' Academy is the new school of the main protagonist Miho Nishizumi, who transferred in primarily because the school did not practice senshado. This, in addition to the fact that the school has been losing money for several years, placed it at risk of closure at the hands of the Ministry of Education. Until the club's revival in the events of the anime series, the school had no overall focus and lacked any outstanding features.

Oarai's only notable feature, its senshado club, was suspended many years ago for unknown reasons. The school is far smaller than other schools shown in the anime, and has lately been losing students. Oarai Girls' Academy is a school originating from Oarai Town, Ibaraki Prefecture, Japan.
