Adaptation of Ishio Yamagata’s Tatakau Shisho series of light novels. In the story of the light novels, all the dead people of the world have been turned into “books” stored in the Bantorra library. A boy named Koria Tonisu has had his memories erased and his chest embedded with a bomb. He is sent to kill Hamyuttsu Meseta, the world’s most powerful armed librarian. However, he falls in love at first sight with this beautiful woman in charge of the “books,” and he gets enveloped in the great war over the library.

Senou Natsuru is your normal, everyday high school student. He´s been chosen to be a Kämpfer (German for “fighters”), whose objective consists of fighting other Kämpfer with either guns, swords or magic. However, there´s a couple of catches; you can´t chose if you´re a Kämpfer or not, and you must have the body of a girl in order to use your powers.
