What's the Saddest Anime you have ever watched.

The Saddest Anime I have ever watched was an anime by the name of Anohana. If anyone has ever watched this anime then you know exactly how I feel. The story is very compelling with allot of tearjerker moments, so many times I thought I had the premise figured out until the climatic ending. If I had to rate this anime I would give it a 9 out of 10.
