My players for my magical girl game basically started talking in terms of aspects spontaneously without my really explaining them. One player mentioned that he thought of his character as coming from the country but wanting to go to a city (where the game would be set). I said, "Maybe she could be the Mysterious New Girl or the Naive New Girl staple." His response was, "She's definitely Naive. Her basic characteristic is being Unfailingly Nice (To The Point That It Hurts Her)."
