Easily a 10/10
I honestly couldn't find anywhere else to talk about this series so I had to come here and talk about it because I really miss it and I'm looking forward to volumes 13 and 14 to end this clinical masterpiece.
The anime without a doubt is great, but the novel is way better in a lot of ways. Notably the detail that I think the novel manages to deliver the reader more of 8-man's character to them and his thought process over situations.
The characters are beyond masterpiece all of them have a fitting role and are relatable to every single one of us out there with a life. Yukino and 8-man often have these interesting conversations about one another's ideas and they always captivate me to want to watch more. Yui adds the cheerful factor that is essential to an initially "depressing" series. But it's fun to read. Definitely recommend it.
P.S. This is my first review, dunno how well that went but I tried to share as much as I can.
