I think of myself a fan too. She's pretty good when she play some kind of role, like a top in this case, or the "lucky nipples" vid a while ago. If the AV is purely plotless, then she isn't very special or unique compared to the many busty and un-shy AV performers out there. She is best when the role involves some kind of J-pop idol (back to her roots) or something glam. She's not the hottest in the business but she can rock glam.
SSNI-101 was really good, with a part where she plays an idol. I mentionned it before, but it's the last movie I saw from her and from the movie trailers I've seen from her other releases, the next Yua movie I will watch is SSNI-178.
