Madoka . . . you missed.

I look at this and the first thing that came to mind was F/SN's Servant classes:

• Sayaka = Saber
• Kyouko = Lancer
• Madoka = Archer
• Mami = Archer (as well.)
• Homura = Archer (because of all the firearms she can use) or Assassin (because of her power)

I find it weird Mami is holding one of her rifles like a pistol/assault rifle though (i.e. it has a handle grip). The other one is held correctly. (Well, not really. Looks more like a club hold than gun hold.) But it's not like this image is going for accuracy, so *shrug* ^_^
