I picked up a copy of Tengai Makyo Kabuki-Den last year. It didn't have the instructions, but it had something unexpected in the second CD tray.
It's a Shogakukan demo for the game. I hunted around for information on it, but I wasn't able to find out much.
I'll probably sell off my copy of Kabuki-Den, and that includes the demo. It was easy to find out how much Kabuki-den is worth (it seems to the PC Engine equivalent of a Sega Genesis sports game), but I'm not sure about the demo. I did turn up some very old threads in which people were looking for it, so I figured I'd post about it here.
