I don't actually think this is about colonization. If you look at it, it is more similar to a warring states type story.
A good example of this is Kingdom.
Also any Oda Nabunaga type stories...
This isn't really one aggresser going and attacking random people, this is a bunch of countries always at war with one country trying to unite them.
The characters literally said they are colonizing those countries. There were only 2 countries at war with each other, the others have "bad" leaders and so they colonize to "make it better"
I still love the story regardless.
I really love this comic except for the part where they make colonization look like a good thing- which is the exact kind of mentality the real world colonizers had ╥﹏╥
