I'll also post a hypothesis. A common plot trope for this shows is for the heroine to become incredibly important and powerful at some point, only to have it later fade away and the protagonist take over. Geats is the most recent and striking example. What if something similar happens here? What if the entire show is Baku's dream, where he realizes his dream and casts his beloved Nem in the lead role? In this episode, his dream scenario has reached a dead end, so he'll have to start a new one. So Baku will ultimately end up being a deity of sorts, albeit a dream-world one. And I imagine there will be something else that poses a real threat, but it's hard to say for now.
