Battle Skipper

Battle Skipper is a 1995 three-part OAV directed by Takashi Watanabe. The story revolves around the Etiquette Club at St. Ignacio's School for Girls, whose members acquire the skimpy outfits they wear while piloting state-of-the-art military mecha, known as BSs or Battle Skippers. The mecha pilots, called Extars, aim to eliminate evil from the world, countering the schemes of Sayaka, the president of the rival Debutante Club, and her accomplice Todo.
