"Natsume’s Book of Friends has been around in manga format for over eight years and the series has been given multiple anime seasons over the years. However despite the first anime season coming out in 2008, the series remained unlicensed in the West until last year when NIS America acquired all four seasons of Natsume’s Book of Friends for release. Now that the first three seasons have been released, the fourth and currently final season of Natsume’s Book of Friends has been released to stores. While the manga may still be ongoing, does this fourth season bring the series to what may be the end of the series?"
