I have to disagree here, because we
are talking about fictional people here and not real human beings. The vast, vast majority of huge-breasted anime heroines are designed by men for straight male consumption and no amount of "but women IRL can look like that" will ever justify the obvious fetishization on display. It's particularly weird because it's become so normalized that the representation, at this point, is completely removed from anything resembling reality - you'll find
far more huge-breasted women in Japanese-made video games and anime and manga than you will ever find in one place IRL, and the reasons for that are completely obvious. That's not even mentioning the fact that real women are frequently overlooked as references for the body types they so espouse, and on top of the fact that
reality itself has a natural selection bias towards specific body types for women of any level of athleticism (seriously, the industry-wide refusal to depict women with actual muscle is
absolutely infuriating) that is usually 100% completely ignored in these works.
If they were, in fact, representing reality in some way with these designs, I would have a lot less to complain about, but they're not. It's pandering towards specific straight male preferences and nothing more. The sheer over-representation itself says a lot. I can't ignore that. I can't excuse it. When it's shoved in my face over and over again on a daily (literally daily) basis with no end in sight, I
must complain about it. What do you suggest I do when we're so inundated with torpedo tits that I literally can't play Japanese games without at least one character shoving them in my face constantly because some guys really, really want to pop a boner ALL THE TIME? Must I really learn to accept this status quo just because
some women in real life happen to vaguely (ever so vaguely) share those proportions? It's such nonsense.
Let me say again: If I actually got to see female characters modeled after real athletes, and if the number of such exaggeratedly proportioned women were at least somewhat in step with reality (re: they're quite rare), I would not complain about this. But we're not there. In fact, the only women in all of FGO's 100-odd cast of female characters who actually are visibly rendered with any sort of athletic musculature are Penthesilea and Hundred-Faced Hassan, both of whom are still rather small in stature and both of whom wear hilariously bikini-like outfits. Meanwhile, we have at least a dozen female characters with what I can charitably describe as "large bosoms". What's with this lopsidedness? Why does no one ever seem to draw inspiration from, say,
actual Olympic athletes who represent the peak of human physical ability for our great heroic fictional characters, instead of generically thin and featureless proportions with excessive curves? The answer may be enlightening. Consider it.
