i doubt it will ever happen she is a doll and she is a great model but she was one of the most conservative jrs i saw. her photodshoots were great but not nearly as provocative as say tomoe yamanaka or nanako nimi. that beind said i shocked just by the pics posted here the but cleavage and the one on the fire hydrant holy.
You never really know. Money is pretty powerful to women, especially in Japan. I wouldn't be surprised if former Jr and gravure idols, work at soapland (mizu shobai), when they get older. Basically brothels that perform sexual actions, but no penetration. Females at those places make around $30,000 a month.
The former actions can never speak for the present or future. Nanako, she had the most seductive faces and body language in her pictures and videos, but she went to stage acting. Some of the cutest AV actresses, were prude honor students in school and ended up doing AV.
We just have to wait and see.
