I love the subtlety and unexpected depth of this chapter.
Orochi has a severe minority complex towards Oden Kozuki and is even after 20 years so paranoid of just the image of him in his mind that he gets mocked for it by almost all of his subordinates. Yet, in the end he's exactly right and Yazu perfectly used that tension to pretty much manipulate everyone into believing what he said.
You could even say he scored a perfect victory if it weren't for the fact he (supposedly) died, but then again that was his intention in the first place. Lies turned into truths and vice versa in such a fluent manner I'm not even sure what is what. Was he now the Witching Hour Boy or not? Did he simply pretend to be him so that he would be executed or was he really him, but intentionally botched it so that people wouldn't believe him in the end?
Love the psychological game he played and his last taunt of Orochi was plainly brutal in all its simplicity.
