In my dream tonight I got to be a small school girl (trans much?), and it made me want to create a game where you get to play such a character. In first person, of course, for that extra perspective shift.

It would be about balancing school life with solving magical mysteries. You'd be:

packing your school bag in the morning depending on the classes that day, taking your lunch with you
managing some basic stats like energy, getting boosts from candy you can earn / buy
doing schoolwork, if you're doing well you get rewards from your mom like more allowance, or for science class get a lab coat (+psychic defense?)
or.. you could avoid doing school stuff to focus on.. other things, which will get you reprimanded
make friends through chatting, actions, dares, or sharing candies or other collectibles they might want
take said friends out for your post-school mystery solving shenanigans
or.. do it during school hours, but you gotta avoid adults that clearly know you're not supposed to be around at that time

So you'd go around collecting clues, artifacts, fight the baddies (or perhaps even talk things out?), until you can eventually unravel the big mystery..! Or something like that.
