Ok, spoiler theory in the text
If Satsuki is Ragyo's daughter, and Nui is Ragyo's fiber womb baby, does that mean Satsuki and Nui grew up together?
I saw someone mention that it's almost like Nui looks up to Satsuki and Ryuuko as older sisters. Do you think that Satsuki and Nui knew that they were relatively "siblings"?
Or do you think that Nui and Satsuki were kept seperate and only met later in life?

I think they knew one another, but by the time they were introduced Satsuki had already established her opinion on clothing, or had begun to, and what not, so she didnt necessarily be the best of buds with Nui. + When Nui is introduced Satsuki does have a familiarity with her and says some things that cue you in on that they've known one another for a while.

Building on that, whenever Nui makes an appearance close to her 4 Devas (I'm specifically recalling both Uzu and Ira) Satsuki immediately loses composure and yells at them to run. This hints to me that maybe Nui has killed a couple of Satsuki's friends in the past. Either just for fun or, if going by your theory, because Satsuki was friends with them instead of Nui.

Yandere does fit Nui very well. Eager to see if she reacts any differently to Ryuko's return, or just sticks with her normal pyscho smiles.
