if we ever encounter a Watcher face-to-face i could only imagine that, in terms of this being an ero-game, they'd likely cater to the giantess fetish? idk
but it'd be interesting to meet one, seeing as they'd likely be the ultimate authority given the lore thus far.
that and i for some reason can imagine that if we were to meet a watcher they'd have a yandere vibe and that would be very funny since you'd have to get them to notice you to start with
