Oh god, I remember watching the whole Kämpfer anime when it was brand new, and it's entertaining in its own way, but my god is it fanservicey and silly! I play Natsuru from the manga because it's a lot more balanced and less of a massive joke. Also Natsuru actually does useful things in the manga rather than float along as the story's fanservice bait while the other (actual) ladies do literally everything. (Though, wow... if you can handle NouCome, you could probably handle Kämpfer.)

The sad thing is, Natsuru makes such a convincing girl, several people have already told me their characters wouldn't believe it even if the secret did come out. And this isn't even me being OOC... he's genuinely like that in girl form in canon! xD

And yes, Chiaki isn't very secretive about it. She's told a ton of people about her history already, and she won't hide it unless I have reasons not to spoil the other person I'm threading with.
