Kyoko was not actually sure how fairy wing development usually went, but she knew Corn had been able to fly when he grew up even after his wings went through so much damage as a child--so, probably they regrew, one way or another? And from there, it wasn't hard to jump to the possibility that wings weren't something fairies were just born with. It was probably like puberty?? Except for not being that at all.

So she just nodded encouragingly. "I'm sure it's an adjustment! But they're very pretty~"
