At the same time, they are not THE focus. Dev_is, to me, is definitely going for normies and a general audience rather than any group in particular.I'm a penis-haver, but judging from my experience with the fujos, this definitely appeal to them
Edit:
At the end of the day, the girls themselves seem no different than any other JP girl to me in terms of personalities, the biggest difference is in their designs and low kayfabe.
