This is Ys III: Wanderers from Ys ("Ys3") for the PC-8801, a Japanese game disk set with manual and box.
Only the User Disk, Scenario Disk, and Opening Disk were tested; the remaining disks have not been tested. As is common with floppy disks of this age, there may be some mold present, so we can't guarantee the game is playable through to the end.
