I mean why it should be such a bitter Truth to say that most characters are not already 18. I mean most schools have the fact, that the students are mostly not 18+ unless you are in graduation class.
In Austria if you are 21 or older you are only allowed to sleep with people that are at least 16 years old and in Japan girls that are 13 and older are legal so far I know.
It's the same thing every time this comes up. People pretend to be lawyers without having any clue about the laws. You can't have a JK schoolgirl and go everyone is good officer, move along. Even Harem Hotel had it's moment when Ashley was stripped of her schoolgirl outfit because it offends those with a big stick up their asses.
Most just like pretending fake ids are legit
These girls are just really really retarded.
