Someone mentioned that Ayana doll looks very similar to Terai Yuki 2, over in the Free Forums.  I don't have Terai Yuki 2, and even if, I would not be able to tell...so innocent until proven guilty I guess!  :)

(sorry, replying to glitterati3d above's post, but did not want to quote the whole thing, in case this is too off-topic)

I don't have that figure either.  Sorry, no clue..........
