Thanks for the chapter!
Yeah, I really got it right, in fact the Madarans are mini Saitamas.
After some of the comments I've read, I've come around to the idea that they've taken the Madarans to the castle of the 11th demon king Jachi, it would be very satisfying for this arrogant man to see all his subjects obliterated and him scared shitless (it would be dreaming too much to see him change his countenance from confidence and arrogance to total fear and cowardice).
What's more, I'm definitely understanding Kiva's real role in this story, which is to be the universal punching bag of natural enemies, now that's entertainment!
Apart from everything these aliens have shown, I'm becoming more and more convinced that the Madarans could easily exterminate the entire race of new humanity, giants and plants and animals over humans, but I theorize that they would be totally defenseless against the curse and the parasitic virus, this would give a much greater sense of danger to these enemies that are so far "secondary" and unknown as to how they will be able to eliminate them.
