>>2784087For Mami, she both is emotionally repressed but also cares deeply about about projecting an imagine of someone who has all their shit together, so I can see her looking for relative safe ways to rebel against this false image that she can keep secret.
She would be careful about it, like “forgetting” her bra when she goes on a quick trip to pick something up from the corner store, or taking her panties off just for a few classes at school. This would bleed into her role as being a magical girl, spurred on by a bitter thought about not having any companions anymore anyway.
Except then she meets Madoka and Sayaka, and all of a sudden the idea of them being unaware that she’s doing something so naughty right next to them is as scary as it is thrilling. She would mostly just think about it, keeping her little adventurers to taking off her panties when they come over for tea and cake.
