Comments of chapter undefined of Blood Assimilation

There are four Districts and they do function like a country independently but not entirely as the humans are in an alliance against the same threat, hence sharing the same currency. The Eastern District mostly had Asians and then other races. The Western District had Europeans and Americans and also other races. There are Northern and Southern Districts but those were not introduced completely yet. One thing to note is that the current world or landmass is different from our world.
