The legendary Ama no Hoko imbues the Nine Tails’ clone with enough power to destroy the world. Naruto is overcome by its immense power and lies unconscious.

As a result of having the Nine Tails sealed inside of him, Naruto is feared and hated by the villagers. He trains all alone in the woods, but one day, a certain man appears and strikes up a conversation with Naruto. Elsewhere, in the Leaf Village, a celebration is held to mark Hinata's third birthday, where she meets Neji for the first time.

A young Gaara is hated by his father and isolated by his siblings, who play in the sandbox with Gaara until their father separates them. During dinner, Gaara asks his uncle about his mother and how to feel happy. His uncle replies that the moon makes him feel better when he is sad, and Gaara agrees that the moon makes him feel happy. A young Shikamaru is bored in class lectures and wants to sleep but is punished along with Naruto and Choji by Iruka for interrupting class. They bond as they stand in the hallway and later hang out after school. Shikamaru criticises Naruto for defending Hinata from bullies and the boys later laugh at Ino for getting rejected by Sasuke.

"The fourth Great Shinobi World War has ended. But Sasuke decides to continue his solitary journey—this time to atone for his sins. Meanwhile, back at the Leaf Village, there is a growing number of missing shinobi. As Kakashi—the sixth Hokage—and the others discuss these incidents, the Leaf is attacked by a mysterious group of shinobi."

Orochimaru brings Sasuke to the Coliseum fighting ring, to lure out En Oyashiro, who may have some information regarding the Exploding Human incident. The match is called off when more Exploding Humans appear and the opportunity to meet Oyashiro seems lost. However, impressed by Sasuke’s Sharingan, Oyashiro approaches him in person.

Sasuke begins his own investigation into the incidents. He overcomes many dangers on his path to the truth. The Exploding Humans, the Ketsuryugan, the Chinoike Clan, and the Uchiha Clan—just how are they connected? Where does his journey lead? The mystery is about to be solved...

Naruto had once lived a lonely existence, ostracized by everyone. But Iruka's words and his very presence have supported Naruto to this day. As Naruto's wedding nears, Iruka begins to lose sight of what he was to Naruto, and is unsure of what to say for his message.
