Yeah. And there's also that it wasn't completely harmless, since we see that something grabbed senpai's leg, left a noticeable hand print and likely made her fall there too.
True, I guess at this point I just mentally file Sayaka as completely impervious to ghosts. Plus it got her a girlfriend.
This manga has got me COOKING.
Here's what we know:
Good writeup. I'd forgotten we had a hard date for Aizawa's death.
I really should reread at some point, but I'm bad at looking at my older work.
I assumed the pentagram only appeared on Michi's neck after the dream and wasn't there all along, transferring Aizawa from the desk to Michi, but I don't think we have proof. Michi hasn't even checked the desk yet to see if that mark disappeared. Another thing I'm wondering is if Aizawa herself recognizes what the mark is for and what rules bind her, or if she's totally clueless.
That little ghost girl was missing her eyes. The storage shed ghost had way too many eyes. When the image of Aizawa got corrupted when Michi called out to her, her eyes have been particularly separated from her face, one pulled to the top right and the other to the bottom left. Michi and senpai can both see ghosts and share a special fuzzy eye design nobody else has. There's definitely something very specific in the plot going on wrt eyes and/or eyeballs. I would guess the too many eyes ghost and not enough eyes ghost are directly related.
I'm not sure if those ghosts were particularly important or just one-offs. There's also the long-mouthed ghost at school and whatever that guy Sayaka saw was. Sight is definitely a big theme that keeps coming up though.
I also get the impression there's a more major incident Michi's not talking about. Chapter 1 shows a glimpse of something with a bunch of arms, and she's afraid of getting possessed. Also whatever approached her at the festival looks like something new. There could be some kind of gathering of spirits going on, considering Sayaka's mentioned seeing more of them lately, but whatever's at the top of the mountain is probably on another level from anything we've seen.
If you look carefully at the Perfect Yellow front page you'll see that among the verdure that surrounds Aizawa there are other things, hidden among the leaves, mostly plushies—bear plushies, rabbit plushies, and even a Michi-chan plushie.
I think they might be the other 3 members of De:Lphinus actually: Theia in the top left, Non in the middle right, and a portrait of Ange beneath her. Just going by the hairstyles. I could be wrong, but it would also fit the idol theme. When volume 2 is out we'll have a clearer image, though I doubt it'll show much more.
On a tangent I'm kinda shocked the idols still haven't made a real debut as characters yet. We saw some behind the scenes hints in the first few chapters, but they've only made background appearances ever since. Then again they just plain didn't exist in the original twitter version (which only went about as far as chapter 5). Still, Dorothy's drawn more side art of them on twitter since the serialization started than they've gotten in the manga itself.
I'll admit I have an unreasonable fixation on the mystery of Theia: she's often shown paired with Aizawa, had strong feelings towards Aizawa's death, deliberately cameos in practically every chapter, had a damn pentagram randomly inserted into one of her speech bubbles—there's got to be something there. I'll eat my translator hat if she doesn't do something in volume 3. But maybe that's waiting until Aizawa gets unbound from school.
