The only place I've managed to find is DoujinGravity Remaster which is where I grabbed it from. http://doujingravity-remaster.blogspot.com/2017/02/remifura-supirittsu-2.html

After DoujinGravity-Remastered shutdown, all traces of this game disappeared off the face of the internet. Luckily, I found a copy and uploaded it to the Internet Archive, which you can find here: https://archive.org/details/remifla2
