Also, I get the idea that this might lead to the "Dark La Verita" issue being resolved, somehow, buuuut ... how about it first "infecting" the other two too? Come on, we should get to see that as well ;)
Finally someone asking the real questions. I've been wondering that for a bit now. When are we gonna get Azure and Sulfur's Dark La Verita?
Not going to happen. There's no one other than Baiser who could possibly make this happen, there's pretty much no chance of her losing control like that again, and she's certainly not going to do it willingly, considering how much she's against even the existence of Magenta's dark La Verita.
Uncle should've remained a man, makes the story feel more grounded, not every manga has to be beauty pageant with 404 men not found, i wonder if authors editor suggested that.
As discussed earlier here, it's far more likely that this has less to do with "beauty pageants" and more with the topics s/he needs to speak about with the niece becoming far more awkward with a man.
