I'm a librarian who loves anime, manga, and reading a wide variety of genres.
A part at the end reminded me of a manga I read a while back, in which zombies were most likely to kill and eat their former loved ones - the living person's desire to hug or kiss the people they loved most got twisted around after they became zombies.
Anyway, this had some lengthy slow sections and wasn't overall as creepy as I'd hoped it would be, but I did enjoy it, despite my reading mood suddenly shifting to "not this" in the past few days. The last 30 or so pages were very good.
Hopefully I'll manage to write a full review tomorrow.
