Sailor Victory

In the pre-WWII era, Nakano Naval Academy's special school for girls is codenamed "Virgin Fleet". These girls are gifted with a special form of power known as "Virgin Energy". With the fear of another Russo-Japanese war imminent, rookie pilot Shiokaze Umino must hone her powers to save Japan from complete destruction.

Old school is back! And girl power reigns supreme! Ayame, Sumire, Renge, and Satsuki are charged with the protection of the Earth from a powerful new enemy. But these girls may be in for more than they`ve bargained for! They`ll have to not only master the experimental mobile armor: Z-Mind, hold down their part time jobs, all this while keeping their lives... normal! But will this be enough to stop the forces of evil from conquering the Earth?

Despite the title, this is not a feature but the three-part OAV Battle Skipper (1995), which Takashi Watanabe directed before going on to Slayers. When the members of the Etiquette Club at St. Ignacio's School for Girls go down the tubes--literally--they acquire the skimpy outfits they wear to pilot the unfortunately named BSs or Battle Skippers, state-of-the-art military mecha. As "Extars," the Etiquette Club members fight to eliminate evil from the world, which means the bizarre schemes of Sayaka, the nasty, super-rich president of the rival Debutante Club, and her flunky, Todo. The series was created to promote a line of robot toys from Tomy, and viewers who are willing to accept high school girls' quarrels escalating into battles involving satellite weaponry may enjoy these silly adventures.

In the near future, Earth is at war with aliens called Worms. The war leaves the population of Earth decimated, with young men the main casualties. The Worms were beaten back but their re-emergence heralds the creation of a mecha unit called the Sonic Divers, piloted by 3 young girls to counter this threat.
