I wonder what the spirits around her are supposed to be like. They seem to not harm her at all, but they're obviously attracted to her like a magnet. It's weird because it's established that "good" and "bad" spirits exist (see: Cat chapter, Miko's father) yet bad spirits (at least visually) are attracted to her and don't seem to do anything to her beyond cause minor insignificant phenomena like making a light bulb go out or something.
Hell, we technically haven't even seen them harm Miko either, have we? Can they even do anything beyond that at all to begin with? I dunno. Maybe they are virtually harmless to living beings and they just look horrifying.
