In Clyde Gentry's No-Holds Barred, an MMA organization named Kage Kombat is said have originally used the octagon. The art-director for the early UFC's, Jason Cusson, claims in Slideyfoot's UFC 1 review that no one involved with the UFC was ever contacted by Kage Kombat.
What I want to know is if there's any way of knowing if Kage Kombat both promoted events before 1993, and used the octagon during that time? Sherdog doesn't list any KK events before 1998, although the earliest event is listed as "Kage Kombat 6":
Kage Kombat apparently used Pancrase-style rules and held fights on a monthly basis for a time in San Pedro, California. It was shut down by the CSAC in the early 2000's, but came back as regular MMA a few years later (Jake Shields fought in the new shows). Here's their outdated website:
The founder of Kage Kombat also has a Youtube account and has posted several news features that profiled the event in the late 90's:

So does anybody know anything about this? Are there any older guys that have experience with it?
