At first I was confused at how Sorawo's eye could literally turn Kozakura into a plant, and why she would think it worked that way, but then I remembered that her eye changes the way that everyone interacts with the Otherside entities. Still, things are apparently the same from Kozakura's perspective either way. And did her form change back when Sorawo focused on different "layers" of the phenomenon?
I'm starting to wonder how the doppelgangers work, how they're connected both to the person who is viewing them and the person that they resemble. The first time these kinds of illusions came up, it was when Abarato briefly mistook both Sorawo and Toriko for his wife. Soon afterwards, he mistook Hasshaku-sama for his wife (though the illusion wasn't complete at first, but he claimed that it looked more like his wife as he drew closer), while Toriko saw Satsuki and Sorawo saw Toriko. Now, they've found Satsuki and Sorawo herself in Sorawo's phone, followed by actually seeing Sorawo's doppelganger in the Otherside and then seeing Satsuki in place of the windmill thing. Do all of these illusions have different causes and different rules? Are they purely illusions? Are they solely drawn from the viewer's mind?
One reason why I'm curious about this is "Satsuki's" strange eyes. Supposing that her image is drawn solely from the mind of the viewer (or one of the viewers, anyway), one would assume Satsuki already had eyes like that when she was around; but, if that was the case, Toriko and Kozakura probably wouldn't have been so perplexed by Toriko and Sorawo's mutations. So it's unlikely that this image of Satsuki was simply taken from Toriko's mind. Does that mean that Satsuki is projecting herself intentionally? Or perhaps Otherside entities are capable of taking on the image/form of anything else contained in the Otherside? Or it embodies Toriko's fears of what Satsuki might have become? I would bet on a combination of the first two possibilities. The fact that the windmill, some of the flowers, and the emblem on the spacetime men's uniforms all share a similar basic shape makes me think that there might be a meaning to shared appearances in the Otherside.
