That's not to say there is no development at all. I think we get to see Natsume grow closer to the friends he has already met, and establish a few new friendships going forward. I want to single out just a few episodes for this review because while I could talk about each and every episodic adventure I'd be here all day if I did.
The first episode I really liked was when Natsume meets someone from one of his old schools where he was bullied for being a "liar." His childhood was so messed up because of his ability to see youkai that he tries not to dwell on the past much. This episode drags the past back up to the surface when he runs into one of his old bullies and the guy sort of forces Natsume to reconnect with him. But when it turns out that this guy has been seeing a girl who turns out to be a youkai he realizes that Natsume may have been telling the truth all along. I think it's a great insight into how much Natsume has grown and it's really cool to see the once bully come around and actually start to be one of Natsume's friends.
The next one I really liked was when the fox-spirit from the first season comes back. This was one of my favorite youkai because who doesn't love fox lolis. Well it's gender is actually unclear, the English subtitles defaulted male pronouns while in Japanese pronouns are usually implied and gender-neutral, and spirits aren't usually assigned any gender but it looks like a little girl. Could be a trap, but I'm sticking with my first guess. Anyway it's the most adorable thing ever and I wish it was in more episodes because every time it's on screen it's fantastic.
Finally I liked the episode where Natsume has to search for the broken glass shards and actually starts to rely on his friends a little more. It shows how much he's come to trust others despite his completely untrusting nature due to his childhood. Tanuma in particular has really come to be someone Natsume can go to and confide in about things related to spirits and the supernatural and it's great to see he finally has friends. Heartwarming series with a lot of great characters 9/10
