So something I can't quite get out of my head is the idea that SUPER-R-U predates Uzumaki (Ito's spiral story).
What if Ito got the original germ of the idea for Uzumaki from this machine (or another like it), rather than the machine itself being base on the works of Ito?
What if we're running into so many dead ends when we're looking to connect the pinball machine to Ito because it isn't actually an Ito machine - just a huge influence for a lot of his work?
