A very nice surprise, this manga starts a little small, but if you can get pass the first chapter you are in for a really great story. Every chapter can seem cold and disconnected... but they ar not!. I don't want to spoil it for you, but you have a bit of pacient with this manga you will get very great rewards.
This is a masterpiece. The story of the humanity exploring space, finding new possibilities, discovering it's own limits. It's not just some sci-fi, it's a fine portrayal of human nature. The art is obviously reflecting the '80s, but even if it's not your style this is a pearl you don't want to miss.
