Not the twerp alliance to protect her!
Wonder if whoever that person is - player, game dev, character with a faulty script (the original third sister?) allowing them to go out of their intended boundaries - has become a painting beast. The Lady Ning arc definitely was foreshadowing the existence of millennia-spanning painting beasts, and implying that the game may actually work much the same as the world in the painting... so I take it whoever that is, they have become a similar existence to her, having accidentally cultivated their powers over millennia of this game being reset over and over and over again.
