Virgin Fleet

It is the early 20th century, in a time when Japan was wracked by war and bombings which seem to never end. In order to protect its citizens, the military has sponsored a special academy for young ladies to harness their virgin energy, a special fighting power possessed only by, you guessed it -- virgins. With this newfound power, these bashful women have the power to defend Japan from invaders! That is, as long as they can keep their pureness intact!
