I was under the impression that Ace went there on his own, with no presence from other WBP crew.

I think it be "cooler" if it was the other way around, Ace taught Kinemon (or the other Wano samurais) how to integrate fire into swordsmanship, thus born the Foxfire technique? And they Wano samurais perfected the art to the point that they could cut fire itself
