M'kay, first off: I apologize for reminding you of this character and the arc she's associated with. Secondly: I do not intend this to be sexually oriented, so please, if your brain takes it that way, please keep it to yourself.
Now, with that out of the way, I have a minor question.
At the end of Rirukia and Rukia's battle, near the end of the Fullbringer arc, Riruka uses her powers to place herself inside Rukia, popping out again later on to block an attack from Tsukishima. Now, Riruka's powers work only on things she 'loves' or finds cute. These things she can permit people within, such as placing a person within a doll, or a dollhouse, presumably herself included. So wouldn't the fact that she could place herself inside Rukia mean she finds Rukia 'cute'? Minor question, no real meaning. Just thought of it while watching the latest Bleach episode and thought I'd get some alternative opinions on it.
