Well. A repressed prude that needs to get horny to get power. That's gotta be the most op shit ever cuz any pervy shit will set off her magic way too easily. This is gonna be fun.
Hmm, if she gets off on embarrassment, she can just tell him about his past life (after confirming the dude is also reincarnated) which would ensure 24/7 embarrassment
Ahh, I was getting interested thinking they were gonna have to learn how to be sexual after repressing themselves for so long but no instead it's just another "genderbend and fall in love with my handsome best friend" type...
Oh well....
