One thing I hate is the how the sex changing "mechanic" works. If you are male, no matter how masculine you look or even how ugly (example the coach) you turn into a cute/sexy female, and might only look vaguely similar (like Yurina's brother). But if you are female to begin with, you look exactly the same, (with no tits? they haven't shown a girl with big boobs turn to a man have they?) but with a dick (example the president). Unless you're the MC in which you were cute to begin with so your face doesn't change?
