Who was Aozaki talking about when she said Ryougi?


In the 3rd movie, _The Garden of Sinners: Remaining Sense of Pain_ , Aozaki is
staring out the window and talking to herself after Shiki leaves. Who is she
talking about when she says Ryougi, since she already called Shiki by name in
the same sentence?

> **Touko Aozaki** : Shiki might end up being killed instead if she goes
> alone, Ryougi.

This happens at around 27:55.




One possible reason is that

> Aozaki may know the existence of "the Void", another personality which never

However I can't find evidence showing that Aozaki really knows about it.
