Reading progress update: I've read 54 out of 272 pages.

So like this is a male power fantasy horror novel, not something like the Ring. Much more like "Another" where all the women seem to have things done to them and all the men are the doers. So don't let the cover fool you.
So far Ayame has only been described as cute, shy and other descriptions for the "perfect moe otaku woman" The other female character was describe as being only beautiful with her mouth shut so... you can see the tone of where this book is going.
