This is probably the weirdest Manga I have ever read. It is drawn with cruede imaginery. Very, very disturbing.
It is very long and I haven't finished it yet. At the time I was pendant to the last chapters as they were being translated but I had to pause for a while. The re are so many characters that get introduced while others die in gruesome ways when you least expect them. It is a ride.
To be honest I need to start from begining if I want to re-understand the manga and eventually pick up where I left it. I kind of what to do it. This manga is good to put some things in perspective about past success and the human race as a whole. Still, it is one of those that you either like or decide you want it to stay as far away from you as possible.
If it didn't have so many volumes I would probably even consider collecting the mangas.
