This is the Gothic Night Asuke Langley by Sega. Now that I remember back to it, this was the first PVC statue I bought in January 2010 at Anime Los Angeles (ALA). I got her for $15 and the Gothic Night Rei for $20, though I gave that one to someone as a gift. I questioned the quality of it due to its price since I had no idea about figures in general at the time. Of course, I would learn later that Sega just has a knack for making high quality figures for low prices.
According to everything I've researched (IE Google), this figure is either 1/7 or 1/6 and stands at about 8 inches tall. The costume is one of many original concepts, and it just seems like the manufacturers just like dressing up everybody as a gothic lolita. Asuka stands in a simple way, just kind of flaunting the dress. I'm not saying she should be muscled up and ready to choke a viking, but I think it's a little plain for what it is. The base isn't anything too special; just a black square platform to place the figure on. The best thing about this figure is how well it captures the character's facial features and it's just really pleasant to look at. I also like how her hair isn't altogether in once piece, though it does bring up the question of why her hair would do something like that. To be more of a nitpicky bastard, the proportions of this fugre are pretty weird. The length of her legs are somewhere between normal and Bayonetta, basically. There also isn't too much detail in the legs in general, but it works to the advantage of the overall presence.
It came out at about $15 and you might be able to catch one somewhere for maybe $25. If you're just starting your collection, I'd say this is a pretty good piece. For more diehard collectors, there are many more iterations of Asuka to buy, but I wouldn't overlook this one. Sega's Gothic Night Asuka Langley gets a very solid recommendation from me.
