You can't get Rana V3 from the magazines unless you have a Japanese address. Luckily, the magazine isn't the only way to get her anymore. (You wouldn't want the magazine version anyway since she has an updated version now.) You can get Rana V4 here.
Oh, I think someone was asking about the number under Rana's eye which was uniquely generated for every copy of the MMD model.
I recall its pretty much retired, you would have to check the releases contents page to see if it is. Its been a while since I checked on things.
