First she just said that she is functionally an STD and we're cool with that? Secondly wouldn't make sense to do the same thing Denji did with Makima. Because he ate Makima, and a new control devil was born, so wouldn't the same logic apply to Yoru and lil' D? Since the world couldn't leave without control.
This has been nagging me for the longest time. Mugo is kinda like heacte, three beings that fit the same role. Child and adult mugo are in agreement with each other. But the old eunuch mugo kinda hates ja-heon, even though he helped him in the beginning. It's weird interesting that eunuch may have a plan for ja-heon and he's been allowing child and adult mugo to do what they please.
