An unexpected and quick axe. The overarching element driving the plot got "solved" by blowing up Earth. I guess the mangaka drew themselves into a corner by solving every conflict in a few chapters, going "Haha, actually everyone is a good guy", and not really building on the larger political conflict back on Earth.

I hate MangaPlus with a clear passion. I get you dont want all chapters out for free, but give us at all least some kind of payment option to be able to read properly.
