I'm a librarian who loves anime, manga, and reading a wide variety of genres.
Noriko and Suwa's story was pretty good, in a horrible sort of way. Now it's Yoneko's turn, and her story brings everything back around to the kidnapping. There are indications that a mysterious foreigner has been stirring everything up in the building, nudging the women into learning each other's secrets.
Parts of this book have me wondering if it could be classified as a black comedy.
