An excellent season 2, I think it is successful overall. Little spoiler : I loved seeing the Red/Rit couple having a good time together and even getting engaged. Certainly Van and his little idiot behavior was a bit hard to follow but it's good that he ended up changing his mind and evolving afterwards (even if it was a bit long I admit) but it had to be because the demon king must be defeated after all. This season 2 allowed us to develop a lot of characters like Ruti, Theodora/Esta, Albert and many other characters. I really enjoyed seeing these characters change for the better.Don't forget that it's a romance and slice of life anime in a medieval universe so it's normal that the anime doesn't emphasize combat.
In short, I would rate this season 9/10.
