Pretty good, I started it because I loved the anime and the LN reached my expectations, it's hilarious and interesting, there were some part hard to read because of my Japanese level (N3) but it was still enjoyable, completely recommended if you like this kind of humor. I LOVE YOU, DOKURO CHAN!
A perfect volume.
This is the best one yet, every chapter is good, entertaining and interesting. When Kirino starts showing her dere self, you truly appreciate the way Tsukasa wrote her character. Without a doubt, this is the most heartwarming volume of the first four.
