I am giving this 5 stars because I believe it fell unfairly victim to the vicissitudes of COVID and the bankruptcy of Aftershock. Did the Miranda brothers try to fit too much in it? Certainly. But the drama, the hope-in-the-midst-of-doom motif, hoping against hope and suffering terrible loss, these are played to perfection.
I did not particularly like the whole Emperor / Accepters thing - it felt like it came out of nowhere, but again, I believe it was part of a broader worldbuilding that never got to shine.
You WILL be pissed at the ending of vol. 2, especially since there will likely never be a vol. 3. However, as an example of "last, desperate stand", in the vein of the great anime stories of yore, this is a truly good comic.
