I think the most egregious moment in VC4 was probably in the post game, where the requisite anime hot springs scene is placed. Some unlikely allies make some sexist remarks akin to "women don't belong on the battlefield" which pisses off Riley.
Who immediately stands up, loudly berates them for their comments. Because it's a hot springs scene, she does this while naked.
As the game "comedically" censors her.
Her angry rant about "actually, women are super capable how dare you" isn't even subtitled like the rest of the conversation as it's delivered with the extremely fast speed of a crazy shrill lady that's not worth listening to as the camera pans over Minerva holding out two arms hovering in front of Riley's breast and crotch. As the comedy music track plays in the background, I just get flashbacks of Raz's sexism being a character quirk and not a flaw, of the scene dedicated to why when the team gets winter clothes the game flimsily explains why Kai and Riley need to share fabric for their uniform to wear less, just the epitome of what the game thinks of women. Exhausting.
It's not that unique in terms of fanservice comedy, but it remains in my memory specifically because I remember seeing someone claim in a VC4 thread that the hot springs scene was in favor of the women back before I had gotten to the post game myself. I was skeptical but curious and upon getting there, I was just left with bewilderment. I can only guess that the poster mistook a Riley's feminism rant as somehow making up for the fact she gets humiliated or that I had been trolled.
