I can see the problems in that design, if you are a normal woman. Why? Games have lead characters from both sexes, even when they do not have a "defined sex", like a monster. Rarely we see a character that can ignore this, like Amaterasu in Okami. But the catch is, almost everything Vanillaware does is exaggerated. Just look at Odin Sphere: Almost all the females have almost normal proportions, and also the males. But if you look at the monsters or bosses, you see the craziness go skyhigh. To me, the answer from Kamitani was absolutely stupid, and just dumb: He freely delivered bad publicity for him and his company, he might have mined the game in some extension.
I think Dragon's Crown can keep their style without a problem, but let's face it: How many female characters are fat, hugely muscular, unattractive, or even plain ugly? Really, tell me how many games have a female protagonist with a body that is not that perfect, or a female protagonist that is ugly? Show me a female, playable, comparison to Piggy from Enslaved? To Bob or Rufus from SFxTK? If you search through almost every game, it's possible you will find something here or there, but it's never mainstream, it's never in the cover. I really love the style used in Vanillaware games, and I can accept the female characters as they are. But, the response delivered by the head of the studio was a warning about how bad things still are inside this industry.
