This is actually the first time ever that I've felt I had to write something to a manga. Why? Because it took me in from the first page, captivated me and wouldn't let me go - I read all 82 chapters in one go. Also, it's one of only 2 manga that ever managed to make me cry.

What I thought seemed to be most important in the story was morals. What is right and what isn't plays a big role here and you get the impression that the author wants you to decide for yourself on which side you stand.
I loved that it came naturally that I started to think about the value of essential things like humanity, life, justice and love but also about the ethnically much discussed topic biotechnology. Is it right to freely modify the human body, our product of millions of years of evolution? To play god, so to speak?

The characters are pictured very complex yet realistic, perfectly befitting the story, but having their defining strengths and weaknesses.

If you're in for the topics mentioned above combined with a very enthralling storyline, a bit of romance and some shounen-like action scenes then this is perfect for you. And, basically, you can't really define this masterpiece in one or even three genres, it's highly recommendable to everyone. A must-read.
