Well, the fun is getting better, I'm even used to everyone teasing each other and is getting hilarious even. I loved we got to see little Iris again, and man, was I not expecting her to be so amazing! I just loved her, she's a wonderful princess and a really strong girl, she could take on the world if she wanted.
This casino kingdom was great, Kazuma's skills are growing for his benefit in every book and now everyone else has a bad time when he is around. For being pretty useless in the first books, he's become quite an interesting character. Even Megumin and Darkness are a bit changed, way more cynical than before.
The Demon King plot is still there, they still hint a few thing here and there, and I'd love to actually meet the King himself one day instead of just the generals, we should soon, since we're running out of minions fast.
