Again I ask, why do you care? This has all been hinted at beforehand, so the people who say it came out of nowhere are either willfully ignoring what they've read or skimmed through the story. If you don't like this outcome, then you don't like it. Fine. But not every niche interest someone has is a fetish (hell, most trans people and furries are downright insulted when someone says that—with good reason, as it's a super hostile thing to say) and even if it is, again, who cares? There's not going to be any sexual content on the page unless I severely misread the author's intentions, so what does it matter? I mean, I'm absolutely certain there are people with a fetish for metal robot bodies, but nobody says a word when someone posts the flesh is weak Warhammer copypasta. Literally anything could be a fetish, but it only seems to be relevant when someone brings up stuff connected to LGBT+ communities (and yes, furries and those with nonstandard orientations and whatnot go way back, if you'd like to look up the history). Case in point, many of the same people complaining about the most recent chapter are fans of anime that provides "fan service" in the form of little cartoon girls.
