Magical Girl: Contingency

I've been playing a lot of Exedra, so I got inspired to make another scenario about magical girls. Here, you are a contingency measure for when magical girls go rogue. How exactly? That's for you to decide. Maybe you also have magical powers. Maybe you are a psychologist and good at talking them down. Or maybe you just snipe them. I included a SC with a magical girl to deal with, or you can always make up your own.
