I'm still on the fence in regards to Orochi. Even though he deserved to be so unceremoniously offed, in the end it didn't really fell cathartic. Orochi is such a cretin of a character that you just want to have him an end as pathetic and humiliating as possible, but as it is now most people probably forgot he died purely because it's insignificant in comparison with everything else that is going on.
It just doesn't fit the narrative. Especially because Hiyori stated that she was the one who would deal with him, which feels kind of shallow when Orochi gets tossed aside like an aftertought. Also Fukurokuju sneaking away is alarming. So, I'm still inclined to believe Orochi's role is not over yet.
