I've seen the entirety of the...erm...concept. There was no process at all, the girls do not revert back, and like most hentais, the girls want nothing more than to explore the new emotions and hormones they all share. The guy 'tries' to fight against his own feelings, but ends up having sex with ALL of the main ones. Oddly enough, I find the title a bit...harsh. They're not dumb. Merely in preschool/kindergarten. Not only that, they are all female, since there were no sign of males within the grown up students. Odd that.
