Here is a short analogy for this one: When Michael Bay makes a manga with a lot of explosion As a one-shot, it has a lot of explosion and the author had fun making this one. Not much of story on itself, its a landslide win of a technological advanced unknown aggressor against at a least funded unnamed armed faction from the defending side. Kinda hard to see if the defending side are citizen uprising or just a rebel faction making it a make up your own interpretation on what you see. Overall score of 5, there are no protagonist or antagonist that you'll want more theseries and not much story that makes it standout but there is a explosion and doesn't waste a lot of time on the reader.
