Guts Rasengan

Remembering Jiraiya's words about never abandoning his nindō, Naruto creates a fully charged Rasengan, but increases its mass and raw force. It has shown enough power to blast away an entire wall of a fortress and even decimate it in a matter of minutes. This technique can be compared with the Big Ball Rasengan having many similarities, except being much smaller.

Trivia

 * It was believed after the release of the movie's trailer that this was actually the Wind Release: Rasengan, due to its leaking rotating chakra and light blue colour.
