One of the first manga I've read and possibly one of my if not the best looking art style I've seen in manga. I believe the art in quality and style it's the best the manga has to offer, absolutely breathtaking and the author has also done an incredible job with his characters, some really nice development. The golden age arc is also one of my favourite arcs in all of fiction (not only in manga) period but after that it really starts to drop in quality which eventually made me drop it around conviction arc, didn't really liked it that much after the golden age arc...
