More seeing. It definitely seems to be a pretty consistent & intentional theme at this point, which just makes Ch3 even stranger for breaking the pattern.
Anyways, this one's pretty interesting, I think, because it seems to almost extend the idea of "seeing" shown previously into something more... supernatural, I guess? Like, closing her eyes didn't stop the floaters, which seems to imply that the act of "seeing" shown here is something more than just literally looking at something.
Also, I think it's interesting how these floaters seem to congregate around the eyes and mouths of their victims. And with all the holes in Kisa's body shown on the last page, it seems pretty clear that the they're trying to get inside her. But the question is why? And why is Saya able to "control" them in the first place?
