I think it started out as Kagome having to stay home for a few months because she had broken her leg in the feudal era. I'm pretty sure it was Inuyashas fault. She had also put on a bit of weight while recovering. Then she goes back and the demons are attracted to her, Shippo tells her, cause now she has a body. Boobs, too.
I can't really remember anything else other than that. If this seems familiar, please help! I've been looking for it!
