Where can I buy Kotori Habane figurines? I have no idea where to find Kotori Habane figurines.

Where can I buy them?
A simple search for 羽々音 小鳥 フィギュア on Google shows that there is no official figurine for this character (or any of the other characters from this game). There are trading cards (used good) and dakimakura (which are all sold out), though.
