I'm just going to pretty much start and end with that word, it really does make up 100% of what this anime is.
This anime really did pull every single emotion out of me, I found myself laughing one minute then crying the next!
What I really do like the most is how this anime builds up over the 13 episodes, The relationships between the characters is planted in episode 1 then is taken care of so amazingly that you feel like you are growing up with them yourself.
I really can't see why anyone would dislike this anime, if your looking for a Natsume Yuujinchou/K-ON then this is it!
I will be re-watching this MANY times over.
