The girl is a fan of the United States.
One day, she was found by some thing claiming to be a Germanophile System, and then she got royally screwed over.
Damn it, I'm supposed to save the Third Reich? There's no way I can do that!!!!
Note: This book features lots of German wonder weapons, along with all kinds of wild what-ifs involving countries like C, M, and E! It may say she's saving the Third Reich, but... well, you know. Nazis don't have human rights!
Actually, this book should be called The Heisei-Era Girl Forced by a System to Work Hard.
A heavily modified Berlin in the middle of a zombie outbreak - Resident Evil 2 - KanColle - Wolfenstein - Nazis on the Moon Want to Be Idols Too (actually, a silly, lighthearted arc that hasn't started yet)
I randomly found the cover image. Contact me for removal.
