Of all anime I have seen Natsume Yuujinchou able to give a nice prequels something that a must watch. This fourth season is the one I will give a review because it is the one that gives me a heart-stirring. Each Natsume Yuujinchou season has a progressive story and little by little revealed the mystery. The art and sound are still stunning and relaxing. The seiyuu able to portray a calm or compose vibe to the character of Natsume. I also like the eccentric relationship of nyanko-sensei and Natsume. In this season, the one you should look forward to is the involvement of nyanko-sensei. Overall,I did enjoy watching this season it really leaves an impact to me I definitely recommend this.
