Much more entertaining final episode than I expected. Of course, to preserve the power scaling, what have been defeated so far are relegated to diet kizuki... Makes me wonder why the upper six haven't simply taken over the world if they are strong enough to survive hashiras for over a hundred years while continuing to grow in strength. Overall, I really enjoyed that scene; it was ominous, threatening, and had some juicy exposition. I would have actually put it at the end of the episode instead of the beginning.
