Story
It flowed nicely even sometimes it got little bit boring when it was stuck on some problem. But whole idea was surely great. I like the fact that it's about characters, their problems and relationships even it's very action driven.

Art
Definately awesome, nice details, action scenes were just top

Characters
Probably a biggest plus of this manga. I loved so many of them and even I soemtimes wanted to smacked some because they did something stupid it was all reasonable because characters here acts like normal human beyings. Everything they does is beliavable, the good things, the bad things.

Enjoyment
I enjoyed this manga a lot even at the start I thought it's bit boring so I had like three years break but then I came back and still don't believe that it was soo awesome. So give it a time it goes better and better

Overall
Must read, it's deep and bitterweet...
