The world of yokai is a place where there are various kinds of beings some malevolent and some mischievous , some bring good fortune and some are malicious, some who like humans and some are consumed by hatred towards humans. In every episode Natsume finds out how these beings that have lead him to be secretive are not as bad as they are depicted, and in the process can make you cry sometimes.
With a new story every episode I have yet to see any other anime where just 20 mins are effectively used to make the story so sublime and characters so tender that sometimes it makes you cry. Its a feeling which any solitary person would find very restful and comforting. And I think each one of us has that little bit of solitude that would connect with it joyfully. Thats what make this series so unique and genuine. I strongly recommend this for all and see it when you are in nice space of mind to appreciate is thoroughly.
