1) I like Sumire.

2) Woah, Nene; did her brain capacity increase after drinking Sumire's memories? Not that she was stupid before, but damn, the way she figured it all out...

3) Also, damn, I didn't think Aoi's story was that deep. Like, tbh, she really felt like that type of girl that enjoys being popular.
Or the author only decided this plot-route later on...
Either way, her calling out Akane was the best.

4) The plot-twist about Akane-kun tho... wtf |:}
5) And her sexually-assaulting her... no thank you. Why do people ship this. T-T

6) At the end,

Spoiler

is that Hanako willing to sacrifice Aoi's life, so that she can fill up Nene's?

That's messed up.

7) But hey, one a good note, Nene's "fat" ankles haven't been mentioned at all in this volume. Probably the first 5 chapters in the whole series, that don't have that.

8) And the first time I actually liked Teru. Especially in the bonus chapters (except the one with Akane, although, then again, that guy totally deserved it...).
