This is going to be a guide on how to buy digital VNs legally on Gyutto, using Tsui Yuri ~ as an example.   This can indeed be done from a foreign IP adress, so no proxy is needed. That being said, the entire website is in Japanese, so here is a guide with pictures and steps, walking you through it. (NOTE! You must be 18+ in order to make purchases here, obviously.)     NOTE: NSFW PICTURES ON THE SITE! Link to the Tsui Yuri ~ purchase page
