Whose idea was the special? Did it originate with Monkey Punch or Aoyama? Or the production staffs of the Lupin or Conan anime? Has anything been written about it anywhere?
I have little doubt there must have been articles about it in various Japanese anime or manga magazines. But since I don't read Japanese and hence don't follow those magazines, the only way I could find out would be if someone who did posted here. I figure it's a long shot, but I don't have any chance at all of finding out if I don't ask.
