Prologue
Some time after the Second Ninja World War, Naruto Musasabi fights a ninja that tries to attack Shuku. (This is the same scene that Naruto and Nagato envision in the manga and anime.)

Chapter 1
Naruto and Tsuyu's teacher, Shū, summons them to a meeting with Shuku's Third Village Chief, Kokage Mahiru. He informs them of the recent destruction of Ton due to the shifting of Mount Hyakki. Kokage worries that its destruction may be a sign that Kon has rediscovered how to use Gukōizan, possibly with the help of Renge Momoashi, who recently abandoned Shuku to discover the larger world. Kokage instructs Naruto and Tsuyu to find and eliminate Renge.

Chapter 2
Naruto investigates Renge's house to try and learn his whereabouts, and while there he is attacked by a giant centipede. He defeats it, but not before it bites his neck, leaving a mark resembling a cross between a spider web and a compass; he finds this same mark drawn on a wall in a hidden room.

Kokage summons Naruto and Tsuyu to meet with him again the following day. He modifies his previous order to instead have them capture Renge alive and bring him back to Shuku. To help them with this, he assigns Nikaku Onikoma, a sensor, to help them track Renge down. Nikaku was thought to have died during the First Ninja World War, executed for killing his allies. In order to prevent the public from learning he's still alive, he disguises himself as a donkey. Naruto and Nikaku have several donkey-related arguments before setting out to search for Renge.
