The Nastume Yuujinchou series is a powerful and heartwarming fantasy masterpiece among the anime world. I absolutely loved the series and couldn't stop watching till the very end. The quality through all 4 seasons was just superb without a hint of drop-off. The range of emotions and themes covered in Nastume Yuujinchou is beyond impressive. It would have me ROFL with Nyanko-sensei's antics in one minute to within Clannad-esque tears in the very next. However, what truly struck me was how N.Y. was able to find a duality/struggling conflict within all of these different themes and truly challenge the feelings and emotions of the viewer. This was done by creating such spectacular characters from Natsume and his family/friends down to the individual youkai that we meet for only a single episode. The creators do a magnificent job getting us emotionally invested in this world via these relatable and lovable characters. It's an amazing ride (and I hope we get another season) as we join Natsume on his journey as he learns to accept and understand his ever changing world, the people/youkai around him, and, ultimately, himself. This is right at the top of my list of must watch anime. Don't think. Just watch.
