A new student named Mitsuki from the Hidden Sound joins Boruto's class. A student named Mitsuki has transferred into Boruto's class from Hidden Sound Village. He overwhelms Iwabe in sparring and shows his genius by solving difficult problems. However, Boruto and the others are unable to tell what he is thinking. Meanwhile, someone who has been doing repair work on the school, suddenly goes berserk. Boruto and the others rush over. Another side of Mitsuki emerges as he starts muttering strange words.

The Ghost incidents suddenly come to an end and Boruto and his classmates are puzzled, but Mitsuki seems to know something they don't. Mitsuki himself realizes he's been undergoing some puzzling changes and questions his classmates in order to figure out his predicament. Soon after, a mysterious chakra begins to spread throughout the village.

The Hidden Leaf Village is filled with excitement upon the arrival of the Kage for the Five Kage Summit. Boruto knows that security is tighter than usual, but he still plans on pulling a big prank. Meanwhile, Sarada has found a new goal, to become the Hokage, and trains hard. Behind closed doors, the Five Kage discuss highly classified intel that Sasuke has obtained involving Kaguya Otsutsuki.

The field trip comes to an end, and Boruto and his friends prepare to return to Hidden Leaf. Chojuro, the Mizukage, sees them off, but Kagura is nowhere to be seen. The class makes it back to the Leaf Village safely and Boruto is relieved to be home. But Himawari isn't her usual cheerful self. She's been looking forward to the souvenir that Boruto promised her, which he completely forgot to get! Boruto decides to tell the truth and beg for Himawari's forgiveness, but he misses his chance, and things gets worse!

Naruto uses all his power to protect everyone from the Otsutsuki Clan. Boruto realizes the magnitude of his father's love for the village and its people and, at the same time, his own weakness. Watching his friends working on repairs and aiding the wounded in the aftermath of the attack, Boruto realizes the meaning of his father's words. Knowing that this experience has matured his student a little, Sasuke brings up a certain mission.

Sasuke and the Kage wage an intense battle against the ridiculously powerful Momoshiki and Kinshiki of the Otsutsuki Clan. During that time, Boruto and Naruto, who have always been at odds, face each other and connect for the first time. But Momoshiki interrupts their reunion.

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!
