My first review, excuse me in advance for my clunky english.
Really solid (And I mean SOLID) manga about the aftermath of a long war, the social, political and technological consecuences of such a war and the personal tragedies (and good fortunes) of the people involved in it.
One point I really liked about this manga is the discourse, specially in the later volumes, about the discrepancies between technological and social advancement in a particular society. Technology advances a lot faster than social conventions and, like in our own world, we get to see how most of the people making the decisions are not prepared
to understand the applicability of new tech and legislate accordingly.
Every now and then the author goes into somewhat deep explanations of the technology and methodology of several branches of sciences, and even the basics of the philosophy of science itself and it's ethical ramifications.
The manga also goes deep into the characters motivations and evolution, and even secondary or tertiary characters get fleshed out quite well.
On top of all this, you also get a healthy dose of action, quite realistic even, not scared of going into real gore at some points.
About the art, at the beginning is a bit basic, but improves along the manga. I particulary like the characters expressions, with a wide and carefully drawn repertory of feelings to enjoy while reading it.
In short, totally recommended, specially for those who like to read about how the different government branches operate and how the individual people in them face the challenges of a rapidly-changing society and the problems that arise from war, be them recent or long-going.
