Boruto overhears remarks being made about his father and him, adding to the hurt because Naruto has broken his promise to be home for Boruto's birthday. Shortly after, Team 7 is given a mission to capture a gang of thieves targeting the Thunder Train, who are hiding out in a town near the Land of Fire's border. But when Team 7 arrives at the town, they find something is not quite right with one of the captured thieves.

Team 7 enters the mine where the thieves had been hiding out, only to be attacked by a powerful, strange-looking White Zetsu. They find out the mine connects to a ruin belonging to Kaguya Otsutsuki. Team 7 decides to investigate and engage the White Zetsu. As they proceed deeper and deeper into the mine, they make a shocking discovery!

The Chunin Exams are fast approaching and everyone’s excited—except for Boruto, which causes everyone grief. During this time, Boruto and his family have a rare chance to be together to celebrate Himawari's birthday, and for once it seems his father has kept his promise...

Unable to contain his anger towards his father for ruining Himawari’s birthday as well as his own, Boruto rushes out to confront Naruto. He runs into Sasuke and unknowingly attacks him but is instantly subdued. Amazed at Sasuke’s strength, Boruto asks him to be his teacher. Sasuke agrees to the request but only after Boruto is able to use the Rasengan. In order to win Sasuke's approval, Boruto trains unusually hard.

Boruto manages to perfect his Rasengan and begins training under Sasuke. He’s an extremely strict teacher because Boruto’s unfocused and only thinks about surpassing his father, and keeps looking for the easy way out when training gets tough. Iwabe, Sumire and the others also decide to take the Chunin Exam and turn in their applications. Hoping to show off his skills to Naruto, Boruto decides to apply as well. Meanwhile, the Otsutsuki Clan set their sights on Killer Bee!

The Chunin Exams are about to begin and genin from the other villages arrive in droves. The Hidden Sand's hopefuls include the Kazekage's adopted son Shinki, and his team mates Yodo and Araya. The Hidden Mists send the Senka triplets, the Hidden Cloud sends Yurui, Iroi, and Tarui. And finally, the Hidden Rock send the Genbu Three. As formidable rivals arrive on the scene, tensions run high as every participant sizes each other up, and prepare for the first round of the Chunin Exams!

Round two of the Chunin Exams begins. For the second test, three-man teams must try to capture their rival team’s flags. Sarada and Mitsuki set out for enemy territory while Boruto stays behind to guard their flag. The Senka Triplets from the Hidden Mist attack, and Boruto finds himself in trouble. Boruto considers using the Scientific Ninja Tool that Katasuke gave him, but it's prohibited to do so during the exam

The third round of the exams begins, consisting of individual battles held tournament style. Boruto’s first match is against Yurui of the Hidden Cloud, and Shikadai is matched up against Yodo of the Hidden Sand. Sarada and Mitsuki are up against Tarui and Toroi of the Hidden Cloud, while Inojin and Cho-Cho pull Araya and Shinki of the Hidden Sand, respectively. After honing their skills in jutsu and strategy, the intense battles between the young shinobi begin!

The tournament nears its finale, as the matches of Sarada vs. Araya of the Hidden Sand and Mitsuki vs. Shinki of the Hidden San begin! Sarada uses her shuriken and Sharingan skills to attack Araya relentlessly, but he counters her with total ease. Her genjutsu has no effect and she is backed into a corner. In Mitsuki and Shinki's match, the evenly matched duo puts on a show of skills.

The final battle of the tournament begins with Boruto, Sarada and Shinki participating in a battle royale. As the lone representative remaining from the Hidden Sand, Shinki is determined to preserve the pride of the Sand, and goes on the offensive against Boruto and Sarada. Boruto and Sarada team up to fight Shinki, but he puts up an impenetrable defense. Sarada falls, and Boruto's chakra is nearly exhausted, but he refuses to give up!

Boruto has made his rounds apologizing to everyone for his transgressions during the exam, but Momoshiki's prophecy continues to bother him.

Popular actors Tomaru and Ashina receive death threats from an unknown person, so Team 10 is assigned to a joint mission with Team 7 to guard them. The two teams assemble to get the details of their mission, but Boruto sees a beautiful girl he doesn't remember seeing before…

The ninja in the gas mask appears again during filming and kidnaps Tomaru. Despite everything that happened, Cho-Cho continues to worry about Tomaru and berates Konohamaru and Moeri for failing to stop the abductor. Meanwhile, Ashina agrees to deliver the money as instructed in the ransom note.

The ninja assigned to the Hidden Leaf Gate are attacked, and Mitsuki disappears. Boruto and Sarada are unaware of this when their scheduled mission is suddenly canceled. Worried, the two start searching for their teammate. When they learn that all the jonin have been summoned by the Hokage, they set out to find out what's going on.

Boruto and Sarada sneak out of the village and head to Orochimaru's research lab to find clues about Mitsuki. After evading the ninja guarding the entrance, they get in. But what they observe at the facility and hear from Orochimaru makes Boruto realize that he never truly knew Mitsuki. Meanwhile, the village finds out that Boruto and Sarada have gone in search of Mitsuki, and Shikadai and his Team 10 are assigned a tracking mission to bring back them back.

Orochimaru tells Boruto and Sakura about the White Snake Sage who lives in Ryuchi Cave. On their way there, the two are confronted by Team 10, which is determined to take the two back to the village so that they are not labeled as "rogue" ninja. But there's no way Boruto or Sarada will oblige until they find out the truth from Mitsuki, so they are forced into confrontation using everything they've got!

Boruto and friends head for Ryuchi Cave in order to see the White Snake Sage. But it's not a simple task, since they have no clue where it is. They search for miles, becoming hungry and tired. They are near their limit when Ryuchi Cave suddenly appears before them along with mysterious women to guide them. They are told they must pass a series of tests in order to meet the White Snake Sage!

The White Snake Sage tells Boruto to bring back the "Reverse Scale" from Garaga, a troublesome snake. Boruto and his friends head deeper into Ryuchi Cave and are confronted by a giant serpent. It is Garaga, the very one they seek, but its sheer power has the gang backed into a corner. Meanwhile, Moegi reports that Mitsuki's disappearance might involve someone who has access to crucial village secrets.

Boruto and the others work together to obtain the Reverse Scale from Garaga. But the battle proves difficult, as Garaga has the power to sense the location of its enemies and turn them into stone. In the midst of battle, the team notices inconsistencies in Garaga's moves and comes up with a successful strategy to subdue him. Boruto is seized with a strange feeling and makes Garaga a proposition.

Mitsuki heads toward Kokuyou and Sekiei's homeland, the Land of Earth. Meanwhile, thanks to the power of the White Snake Sage, Boruto and the others learn that Mitsuki is with Hidden Stone Ninja, and they also head for the Land of Earth. Each side has their own agenda, but will they be able to meet up successfully?

Kokuyou confronts Boruto and the others. Kokuyou, whose only goal is to become strong, is so powerful that he's taken down the Leaf ninja pursuing Mitsuki. He easily drives Boruto and his team into a corner. Just then, backup appears. Boruto and his friends manage to overcome Kokuyou, and finally catch with up Mitsuki.

Instead of returning home with Boruto, Mitsuki stays with Kokuyou. During this time, Sekiei becomes sick and declines. To recover, Kokuyou returns to his comrades. During his absence, Sekiei asks Mitsuki to teach him what it means to be human. Meanwhile, the Fourth Tsuchikage Kurotsuchi, who had been visiting Ohnoki, her ailing grandfather, is attacked by mysterious assailants.

Boruto is injured, unconscious and unable to continue. Everyone thinks about returning to the Hidden Leaf. However, being close to the Land of Earth, a surprise attack is highly possible. As a precaution, Inojin and Cho-Cho set out on recon of the surrounding area.

Boruto and his friends decide to go the Hidden Stone Village to see the former Tsuchikage, Ohnoki. In case of an emergency, Inojin stays back with the young Akuta, who is attached to him. The team secretly enters the village determined to find Ohnoki, but they are unaware that they are being watched.

The team finds Ohnoki, but he flatly refuses to help. On top of which, they are attacked and separated. This leaves it up to each member to make it to the rendezvous point on their own. Meanwhile, Mitsuki is being shown around Kokuyou’s hideout.
