...Really?
I could name you tens of Japanese franchises full of generic, amateurish pap cynically churned out to sell dakimakura. And I'd probably agree with you if Kamitani had made every female character a Sorceress clone. But that didn't happen, and that should be a clue to you that Kamitani wasn't just designing characters as masturbation fodder.
How does, say, the Amazon NOT tell you anything about the world of this game? She is a perfect exaggeration of a
female bodybuilder. All muscle, almost 0% fat. Compare this to other games coming out of Japan. How many of them even acknowledge
muscle tone in women, even women who are supposed to be physically strong—much less put in a bodybuilder and NOT have it be a joke about how "LOL ugly" she is?
Is it intended to be "sexy" as well as exaggerated? Arguably. But titillation is not inherently evil, and this approach is so far away from artless copypaste garbage like Senran Kagura and Caladrius that I'm actually kind of flabbergasted you would conflate them.
