Spoiler for a thought with reference to epi 12:
Through out the series we are led to believe that Yukari really does want to be an astronaut (who wouldn't!), but since both times she has splash landed in her school pool. If the spirit is granting her wishes does that mean she really deep in her heart actually does want to be back in school?
Ofc it could be just to really piss off her headmistress
