I don't think so. She has never acted like she needs the spotlight, in all her videos with other women its quite the opposite. Kita is playing support and showing off the other actress's talents and good sides. Kita seems really to be a good director of these scenes in that she really is focusing on displaying the other talent, we have plenty of videos of kita on her own and she makes the most of it when she has other actresses. I think she takes the backseat on purpose, not that she becomes a background actor in the face of more attractive actresses.
