Hibiki finds himself captured by a ship full of women after being abandoned by his fellow citizens, with the exception of two other unlucky men - Bart Garsus, a cowardly, self-proclaimed ""helmsman"" and Duero, a highly educated student who had become a doctor on a whim to stay alive. Things look pretty dire for the men - but while the pirates are deciding about the fate of their new male prisoners, a mysterious enemy begins an attack on them.

Now, in a life or death battle, everyone, even the men, must work to escape this new threat. Bart manages to weasel his way into piloting the ship (even though he has no idea how to), and Duero makes use of his medical skills. A despondent Hibiki, left without anything to contribute, feels that he can do nothing to change his pathetic existence - that is, until the vice-commander gives him some words that he will soon not forget...
