It's not good. This is the manga equivalent of an exploitation movie. You're here to see one thing and one thing only, violence. I'm 50 chapters behind and have no way to get caught up to tell you of anything interesting happens. What have seen in the 160 chapters I've read is scant and miserable. What plot does exist just drags on and has too many characters for it's own good. Star Wars didn't have this many assholes running around at one time in a galaxy spanning war and this is a micro nation that every world power has somehow missed.
