I was wondering the same thing so I checked out the blog and Koha says トラトラちゃん♡ which apparently (?) is Trauden Naomi/トラウデン直美 http://ameblo.jp/trauden-naomi/
Feel free to correct me if I'm wrong. Totally agree though, she is gorgeous and Koha says they are on a photo shoot so can't wait to see the results. :)
