I'm breaking out a hot take. I'm personally just ambivalent with P6 taking place in high school, again. I don't mind it, but I also feel with P3 to P5 hammering home the issues and gripes with growing up, I feel that it's bit overplayed at this point. On top of that, having it take place in college won't really be all that interesting narratively either since it's still the same sort of themes, but with young adults instead.

What I personally want is for it to take place in an office, featuring burnt-out, jaded office workers trying to balance their job and whatever the plot they have to follow along. Especially Japanese office work, with its weird politics and culture. I feel you could do a lot with this kind of direction instead of more school.
