夜神月
When this manga was first serialized, it was criticized by many readers as the series was similar to another manga, "Death Note". This may have been due to the fact that the main character was bored of the world, and he wanted to change it, and age are both similar to Death Note's Light Yagami. As the story progressed however, it became more to do with the main character utilizing hypnosis to change people for the better.
