(Manga theory) The reason the **** was sealed
How can I be stupid, I just realize this now.
So there's been hints about the rain has been absent since the start of the manga, which many speculated that it has been sealed for some reason.
Well, considering the Nishi village is submerged at the bottom of the reservoir rn, isn't the rain sealed particularly so that the reservoir would be drained and thereby expose the village to the open air, and thereby make it possible to lift the barrier of the village, and release the people inside to the modern world?
How do you think about this?
