There are a number of reasons why this is my favorite sereis. I think the overall story and concept of the hell correspondece is really intriguing and brilliant. The animation is beautiful, I love the way it's so realistic and unique. The music is beautiful and creepy at the same time. I also love the charectars but in this season they don't seem to get into them very much, which makes it a bit boreing sometimes. Overall this is a great show but not the best season.
