You don't think hot boy bishies don't amass a female following? This game looks to have plenty of those. How men being more horny due to their testotarone levels and women being more sophisticated handle fanservice in general is completely different
For most anime or manga fandoms in Japan, it works like this unless your specifically selling yourself to the creepy segment of otaku who buy all the figures for their collection, or your appealing to females specifically.
Naoko Takeuchi never designed the Sailors to be sexualized as they appealed to the shoujou demographic, yet the argument you would hear from the west is that they were designed by males by committee to be sexualized when that was never the case. Its a different type of cultural view.
The problem being that the female designs tend to be denigrating in a way that the "hot bishi" designs are not.The male characters are straight up designed to appeal to female otaku. That is what you don't get, because you think they need to be equally sexualized (i.e. showing the same amount of skin, because that's really all we're talking about here)
The things those two audiences want are not necessarily equal
Why do you think the guys are pretty boys in skin tight clothes if not for that?
These designs definitely don't appeal to all women, but neither do the sexualized female characters appeal to all men. They're made for a very specific audience they are targeting. And that's fine. There are other games made to appeal to other people.
Personally, I don't mind too much as long as they have half-decent character creation and a selection of decent outfits, but I really hate it when people deny that a piece of media they enjoy also happens to have some problematic elements. The design is sexist, it's okay to admit that, it's okay to enjoy it, just recognize it for what it is and don't live in denial.
