Actually, I thought that it was one of the best manga's that I've ever read. If it didn't stop so abruptly and so soon, it would have earned a spot in my icon. The plot really caught you and the characters were deep. And what really gets you is the fact that it stopped right when the plot was fully set up and ready to go. If he ever picked up the story again, I'd be the first to continue reading. Sex? None. There wasn't even a nude scene. Violence? It fit into the storyline per-fect-ly.
See, IF it ever continued, it would definately be my favorite manga.
