That's right, it's "Void" himself (it's why she is surnamed Void Shiki).

However, I would recommand you to check this : http://typemoon.wikia.com/wiki/Divine_Spirit

Notably about Balor,  Bodhisattva and Earth Mother Godesses. The first entity hold greatest power than Shiki from his mystic eyes, and the second and third are above Akasha. (Bodhisatva is kinda more or less implied during extra, the second is admitted as they are Akasha's creator).

In factn the only concious that are in the record and act as a "conscious" is Alaya.
