If you have all this, I am afraid that there is no more at this moment in time as the official E-Body site also list these titles. http://www.av-e-body.com/special/keira/ She had a blog - http://blog.livedoor.jp/keira__/ but than again her only entry was in June 2014 so I don't think you can get any information from there. No indication of twitter account on her blog so I guess she don't have one? My guess is that since not much can be found on her blog and the official studio as well, you just have to wait. Unless you know that she also releases under other studio than you can check out that studio official site. For a list of studio official site you can visit this link - http://www.akiba-online.com/threads/official-site-links-of-jav-studios.1123887/ That's all I can help. Good luck.
