ho-ly shit. I have this personal fanfiction about Nodoka that we'll get to see her figuring everything out, and breaking entirely. Like the gods would eventually be like "you know, what? you want to know? fine" - and what she discovers makes her wish she didn't before completely imploding.
Will this happen? probably not. But it would be so cool if that revelation would be in terms with finding out the gods were actually trying to protecting them from something worse. Regardless, I hope we finally understand what Yasu meant with that revelation, and who it was from that the well had almost dried up (Maybe Wires? Since Tsuneyo went away just as the message started - could also had been someone in the Himawari's group since the conclusion was to try to protect Akira, which resulted in nothing).
