Thanks!  I found that first image and I had to put a sheet to her.  Before that I was honestly considering how to make mahou shoujo "Maou Shoujo" with horns and chuunibyou.  I think this will be better than the pun.

Important factoids:
Sam has a driver's license.
Her mother is a newscaster (I think the term is anchor?  The person at the desk, not the one onsite).
Her little sister, Diana, is Diarmi's age.  Not that I expect them to have met, since Diarmi seems somewhat nomadic and Mrs. Walters definitely sent both her girls to private academies.  Although before I commit to that, I should probably see what the hook that pulls everyone into the same sphere is going to be.  It might be important that everyone remain reasonably close outside 'working' hours.
