I had this in my "to do read" for a long time, and with the Covid19 lockdown, I give it a shot. Read it in a week. It was great, strongly recommend it, sometimes I got lost and I had to re read a few chapters, but I never had to google search anything. The story is great, it gets super dark in some places, and it's an emotional trip I don't recommend during the lockdown...
Over all, the scify is pretty awesome, it had several info dumps, and they had to explain 2 times what the heck was going on at the end. (around chapter 120 you get a full chapter explaining the situation and in the last 10 they have to do it again).
From a character perspective, most of them are pretty well written, flawed with their own motivations independent of the MC/Main Plot line, and a good portion of them actually have a full story arc.
From a more "political" point of view, it might be one of the best mangas I read in a long time. The geopolitical narrative is great, showing different approaches to the world after the pandemic, diferente ideologies clashing, not some void realpolitik, or childish baddie versus good guy.
There's too much to unpack, drug abuse, depresion, overcoming adversity, not overcoming it, etc... so many things that some aren't explored in depth.
Over all, awesome
