First off, I should probably give the bad news, this will most likely make any figure collector scream. This particular figure of Shiranui Mai is a Hobby Japan Exclusive, which is a mail-in. So for anyone interested in acquiring her. You’ll have to either use ebay or find a proxy service in Japan.
Sculpted by Chorosuke of Volks, this is one AMAZING figure.

This was spotted at TGS ‘08 at SNK’s booth I believe. No word on what her price will be, but that apparently reservation of her starts on November 25th, which the January issue of Hobby Japan will have the form for her. However, that’s probably wrong unless Hobby Japan puts out issues that far ahead.
I can’t see much for what scale she is, as the paper next to her doesn’t seem to say anything.
The paint job is amazing here! It would also appear that her bottom is cast-off. I will be hunting her down. More pictures of this lovely girl can be found at AkibaHobby
