i checked the raw and there is only 1 page missing. its the page where he saves the saint from the tentacle. i guess the rest is just messy story telling, bad translation, or both.
i'm assuming they mean he will orbit the moon for a couple of weeks before the orbit decays and he crashes into the moon. him surviving is irrelevant to that, his body would keep orbiting even after he died.
unsurprisingly, this manga is going downhill with no sign of getting better. as more and more characters have been added, the art has become much more simple and just worse in general, and characters have been reduced to a single personality trait. they used to have some depth, but now they are...
You need to give yourself more credit bro. These chapters are better than a lot of scanlations I've seen. It's perfectly understandable and the typesetting is acceptable.
