A Japanese Myst-a-like point-and-click adventure game, released using typical anime visuals on the PC98 and with "updated" CGI visuals on Windows 95.
About a year ago I actually bought the Windows version since I couldn't find the ISO anywhere and uploaded it to the Internet Archive. It won't work on Windows 10 but the visuals are all openly readable. I also scanned the packaging and some of the manual illustrations.
