The war begins

In a role-play texting war I had with my friends, we were allowed to use anime characters in our armies, so I decided to use characters from my favourite anime, Madoka Magica. All of a sudden, this sparked an idea.
This story contains girls from Madoka Magica, as well as Magia Record, and maybe also the girls from Kazumi Magica, Oriko Magica, Suzune Magica and Tart Magica, if you suggest.
Disclaimer: I do not own Puella Magi Madoka Magica or any other media mentioned, it's only for this story.
