Some say it's the Torii Seal that Gerotora and Jiraiya spoke secretively of as "that jutsu".
And Naruto shouldn't use it when he is not ready.
Is it Rasenshuriken? But it's not possible since Jiraiya didn't teach Naruto that.
I really think it's some sort of powerful fuuinjutsu, since Naruto is Uzumaki, and probably needs Uzumaki blood to perform.
