I just realized this is supposed for be an ecchi manga... And it's about highschool girls aka underage girls... And it's aimed to the seinen demographic (18-40 y-o men).... Can't you just put them in college or something? Cause this is blatantly for pedos at this point... Fml.
What I mean is that ecchi highschool girls makes sense when the demographic is for kids that age, but why try to sell sexualized underage girls TO LEGAL ADULTS??? I even heard that sexualizing underage girls is a huge problem in Japan... I mean they ban idols from having relationships because they want the fans, of all ages, to be able to fantasize dating them, even if these idols are underage!
