I received an eARC of this book from NetGalley and the publisher in exchange for an honest review.

It's fun to read another Junji Ito work that's one coherent thread instead of multiple short stories. Even though it lacks some of the punch of his other books, I felt like I was able to go on a more gentle, in-depth ride into this strange world where people vomit the souls of other beings trapped in harder-than-diamond, extremely valuable stones. Ito explores the ethics of such an endeavor in a sardonic, nasty way.
