It's no mystery, Evangelion is one of my fav anime but for sure I can't collect all the models available. But this one, although quite old (it dates back to 1998 I think) has always been my most wanted Rei.
It cost quite a lot, but I think it was totally worth it! It's a huge figure, I actually don't know where I'm going to display it. And the cast is excellent! Just the face details are incredible. Too bad the hair is cast as one piece with the rest of the head though.
