Guts Rasengan

Whenever Naruto Uzumaki remembers Jiraiya's words about never abandoning his nindō, Naruto creates a fully charged Rasengan, but increases its mass and raw force. The color of this Rasengan changes from dark blue to light blue. It has shown enough power to blast away an entire wall of a fortress and even destroy it in a matter of seconds. This technique can be compared with the Big Ball Rasengan having many similarities, except being much smaller in terms of size.

Speculations

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