If you've already watched Death Note, you will probably like this anime. It's story is very similar to Death Note. It has a very good plot portrayed by good characters. Its animation is pretty good too. The only downside of this anime is it only have 11 episodes. But despite of this small number, they still managed to fit an entire story in it without destroying its storyline. Its a really good action and mystery type anime that you can watch.
