@Bistai: I'm afraid your memory is lacking somewhat. This chapter of the WN is FULL of Anne-Sophia's thoughts. We got this explanation from her perspective, after all.
@JeDePi:
Guys, this is a manga adaptation. Things are being streamlined. She's put a fair amount of testing behind her theories, but the manga doesn't expound on that because it would make an already exposition-heavy chapter even exposition-heavier.
Also, really, when trying to explain the basics to...
@Dark_Tifanny69: They're 2 years apart. L'il Sis is in the same class as Rin, who's a first year, while Big Sis is in the same class as Ryuu, who's a third year. Basically, they've got until the end of this school year to find each other, or Big Sis will graduate and go off somewhere and they...

And we begin to grasp just a bit more about how the other side works. It burrows into human brains, changing the way they work. With that in mind, can anyone trust anything they perceive over there? As Kozakura said, can the two of them even be sure they're actually having a conversation? What...
I don't think there's any possession going on. The fact that the tiny girls have no memories prior to waking up as tiny girls (aside from knowing their own identities) makes me think that the little ones are actually copies and the bigs ones are the originals.
