Has anybody thought about that jutsu nauto is supposed to use.
When Jiraiya and Naruto came from their training trip, he told naruto to not use "that jutsu"
Thn again when Jiraiya was about to fight pein he spoke with the toad. He said that Naruto needed to control the Kyuubi's chakra to complete "that jutsu" and that him and minato were working on but didn't finish it.
Then when naruto was about to go to the island the toad told him that this was the final to completing "that jutsu".
What do you guys think the jutsu is?
