"Alliens" arrive in the country from outside, they get high ranking positions, the law doesnt touch them (not entirely), the 100% of them are rude, all of them are rich, "government cover ups", they stink so much even when they die the stench doesnt go away, 20+ million in number, they are "replacing" the natives. Racist BS i have heard a thousand times from europeans, americans and many others with all that bs backed by nothing other than insecurity that now gets made into a manga with protagonists that kill and eat those "alliens"
The story even without judging it on its obvious pararells to reality its a very bland story with nothing to offer other than controversy and a soon to be cancellation after said controversy dies out and the numbers plunge on the ground
