The relationship between the main character and villain is what makes this anime good. Surprisingly, only one point of view is given, and the two main characters hardly ever interact. The protagonist displays emotion rarely, leaving the viewer free to imagine what he may be thinking. However, some subtle clues are given, and it seems as if he is asking the same questions as the audience. What makes a man evil? Is there still good left inside of him? Is there any hope for redemption?
