Alternatively, Naruto's been spamming that jutsu for years, so if Kojin can learn some high-level jutsu like his True Flames, he might've deduced how Rasengan worked on his own.

But really, that exchange gave me Kakashi V Zabuza vibes, so i'm looking at it from that angle. oh wait, one can just make contracts with Toads from Myoboku by meeting some toads and learn highest level shape transform just by seeing. That would be just mother of all coincidences and probably lame story, Especially after him revealing that he is from Konoha. Put it in a nutshell, The Guy can be either Jiraiya or his student. Plus he also has to be close enough to Minato to even know the information behind its creation. If we take everything into account, it can either be a person from original Team Jiraiya of which Minato was part of or Jiraiya himself. We already know Minato is dead so it could be other two teammates. If its not this than we are looking at Bardock 2.0 with Time Travels.
