Natsuru used to dream about being a real lady-killer, but being turned into a Kämpfer, a female fighter who's supposed to fight and kill other girls in combat, was NOT what he had in mind! To make things even more complex, (s)he's only a girl part-time and (s)he'll be moving in with three other gorgeous Kämpfers (who are all actually all woman all of the time), for mutual defense. And the fact that more than one of them may have less-than-honorable designs upon Natsuru's alternating sexualities couldn't possibly be a problem, could it? Of course it could, and things REALLY get hopping when Natsuru has to take a job at the Bunnygirl Café! Find out what happens when getting in touch with your feminine side becomes a full-contact, no-holds-barred, battle to the death!
