This original design comes from Cospa and Onsen Tengoku's Resinya! line, which is probably best known for its depictions of the girls from Toradora, although characters from To Heart, Da Capo, and even Combat Butler Hayate have also been spotted. (Remember those busts of Hingiku and Nagi?)
And she kind of looks like something out of dot hack. But I won't deny that Blog Fairy (Yousei) Kokoro is pretty cute, even if orange isn't my color. But I think I like her a lot better with the hat on than with it off, and the little crotch-zipper on her skirt is a bit weird (and vaguely Squenix-like). But ¥12,000 (about $127.50 USD), I think I'll probably pass on this particular fairy.
