This is a sequel to the earlier Marubatsu DX game by the same developer, but for the PC-8801. In any event, you chose from one three girls, and play strip tic-tac-toe with them. That particular game is a rather odd choice given how simple it is, so prepare to play a lot of games waiting for the computer to screw up. If you lose any of them, it's back to the start.
The software group's website is still up, and you can see the description/gallery page for this game here.
