This game doesn't have an 18+ ver.

Email Winged Cloud about it. I did and the person that replied said they could forward the request on it.
most of the email below:
Sakura Fantasy Ch. 2 was turned down a while ago.
I cannot say if this is ever going to be made or not but I can forward your request for chapter 2.
We can only cross our fingers but I cannot promise anything.
Hope you have a great day,
Kind regards,
Sam from the Winged Cloud support
