>>604243>>604324In order, the girls are from Saki, Girls und Panzer, Strike Witches, Vividred Operation, C3-bu, Umineko, Tamayura, Mondaiji-tachi ga Isekai, Nanoha (as you know), Symphogear, Golden Time, Wixoss, Wixoss, No Game No Life, D-Frag!
Too much work to find their actual names.
>>604332Just similar characters. Somehow, I've only watched No Game No Life out of all of them (And the first season of Tamayura), but most of them actually don't kill anyone. Most of the blood/crazy eyes are edited on there. They're just slightly crazy, is all.
