I haven't finished this yet but I'd love to give it a review already. I'm putting this on hold since I have a lot more stuff to read. 
 The writing style kind of puts me off. I get that it's translated from Japanese but it's just... They could have revised it better. I love the details, though. It's extremely detailed and if you cannot handle reading gore then this book is not for you. I love the concept. What I don't like though is the fact that I can't remember a single name. All their names just meld in together. I don't know why but they just do. It's hella confusing. 
 Review to be continued...
