"Compete with each other for territory because... witches are a limited resource?" she guesses. "Where do witches come from, anyway?"
"Which is why they go around making people kill themselves and similar, I guess?"
"What kind of mortality rate are we looking at for magical girls? ...Is there a less stupid name for magical girls?"
Puella magi is the Latin, it suggests. Well, some of them last for a very long time, if they're clever about how they use their magic. It all depends a lot on strategy and talent. A reckless puella magi who finds herself far away from more witches to hunt, or picks fights with other magical girls that she can't win and then won't back down, or who has very little ability in combat and winds up fighting a powerful witch alone, is going to be in trouble. But a careful puella magi will live much longer than a normal human.
"Ghyslaine is over two hundred," murmurs Solvei. "How many of them last that long?"
"And she doesn't have any magical friends because she's horrible," says Solvei. "It's probably even easier to pull something like that off with allies."
"But only once we pick wishes. Why aren't you allowed to suggest things?" Bella asks the fluffball.
"Huh. So it's important to wish for something you feel strongly about," she muses.
"I mean, that's sort of folded into 'you only get one', unless 'feel strongly about' means on like an emotional level."
"Not sure yet. Have to think about it. Probably not Stasya Koskin. Unless maybe I can give her magic powers and she can kill Ghys for me."
