Derivative works related to "Return to Shironagasu Island" are permitted only for individual production.
We also allow the production of R-18, R-18G and goods.
However, the use for commercial purposes by a company or corporation is prohibited without special permission.
It is also possible to distribute Let's Play videos of the game.
However, as this is an adventure game, we fear that many people will be satisfied with just viewing the game and not actually buying it. Therefore, it would be helpful if you could recommend the purchase of this game in your videos as much as possible.
Thank you for your cooperation.
