When A is seen above the figure, the figure dodges, and is able to fight equally with A. In the battle A is able to destroy the hood, revealing the hooded figure as Naruto Uzumaki. A is shocked, taking advantage, Naruto escapes. As Team Samui and Mabui wake up, A tells them to summon Killer B.

In Konohagakure, Tsunade states that Naruto is wanted for attempting to assassinate the leader of Kumogakure, the Raikage, and killing jōnin from Kirigakure and Iwagakure to Team Kakashi. Naruto and Sakura refuse claims, but Tsunade states Naruto will be placed in Hōzukijō, a criminal containment facility, also known as the "Blood Prison", in Kusagakure. Naruto attempts to escape, only for Yamato to encase him, and Tsunade takes away his forehead protector. When Naruto arrives at Hōzukijo, Mui, the head of the prison, quickly places the Fire Release: Heavenly Prison on Naruto, sealing his chakra. Naruto learns this the hard way after using his shadow clones, Naruto quickly collapses from the pain caused by the seal.

Trivia

 * Despite taking place after the time-skip, this movie drops the "Shippūden" in its official title.
 * The timing this movie takes place is very uncertain as story elements present in the proper story are present while others are not, such as;
 * Naruto knowing Sage Mode, despite the fact that Konoha was not destroyed by the Invasion of Pain.
 * A still has his left hand, despite losing it not long after the Invasion.
 * Naruto knew Killer B, but did not meet him until the start of the Fourth Shinobi World War.
 * Despite the fact that Masashi Kishimoto mentioned that the world of Naruto will not have any firearms, there were plenty of Blood Prison guards holding firearms, such as a flintlock rifle.
