High school life has rarely been an easy thing to endure for the typical teenager. Even more so for Natsuru Seno, an average teenage boy who one day finds himself transformed into a teenage girl. His transformation was caused by his being chosen to become a KÄMPFER (female fighters destined to battle each other). He has no idea how or even why he’s been thrust into such a predicament. Natsuru’s situation only grows more complicated when he realizes that attacks from other KÄMPFER can happen anywhere, and at any time. With potential dangers lying in wait around every corner, how will Natsuru maintain normalcy in his life? How can a teenage boy be normal with a newly acquired, randomly appearing, and greatly endowed female form?!

Natsuru Seno is your standard teenager that goes to an all-boy's school... except when he (through no control or will of his own) transforms into a Kämpfer, a female warrior tasked with taking down those like herself. Now he- or she- must enroll in the all-girl's sister school, but when a newspaper article calls her "The Yuri Girl of Seitetsu Campus," she now is forced with dodging love confessions and idol meet-and-greets alongside the bullets of an unknown Kämpfer looking to taking out the new idol of the school. Can Natsuru survive all this and still get those pictures he promised a friend?

Natsuru’s ordinary life lay in ruins the moment he became a Kämpfer, a female warrior destined to fight other Kämpfer. Thankfully, he’s starting to get used to this split life he’s now forced to lead (one male, one female). If things stayed calm like this, he’d definitely get this all figured out. But where’s the fun in that? With the school festival fast approaching, everyone is riled up and things start to get a little crazy. And when his newfound female self’s popularity reaches a fever pitch, there’s no telling what’s going to happen to this unwilling heroine. But more importantly, why is Kaede wearing a wedding dress?!

Ordinary high school boy Natsuru Seno woke up one day to find that he had somehow changed into a girl. Now he's been dragged into the conflict between battle-driven beings called KÄMPFER.
