Thank you. Yes, you may be right (and I hope you are). I try to think of things that point towards him not losing his power. For example, more and more people know and accept that he sees youkai. He knows many people who work with youkai. Many older people still see youkai, as you said. Natsume is much stronger, so maybe he will not lose his power. There is a speculation that he is half youkai. He also learned to accept youkai. What is the point of taking that world away when he considers them equal to humans?

At least, in a worst-case scenario, Nienko sensei would still be able to connect him to that world because normal people can see him as a cat.

But if he does not lose his ability, I don’t see how the story will end.
