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 shadowy, warped chakra that only Boruto can see takes over more people, causing them to rampage. It only affected people within the Academy at first, but now it’s extending its reach into the village. Can it be stopped? And later, a Visual Jutsu places Boruto within a dream—and afterward, Boruto declares the dream has awakened his Byakugan, the Kekkei Genkai unique to his mother’s Hyuga Clan. Naruto does not believe him, so Boruto seeks advice from his grandfather, Hiashi Hyuga.

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.

Sasuke sends a message to Naruto about a man possessing the Sharingan. Upon receiving the intel, Naruto rushes to meet with Sasuke. Meanwhile, Sarada, who has doubts about who her real mother is, joins Cho-Cho, who is about to set out on a journey to find her “real parents.” Upon learning that Naruto is on his way to meet Sasuke, they go after him. But danger looms when they come under attack.

Sarada is in shock after Sakura is captured by Shin's jutsu. Even Naruto, with his exceptional tracking skills, is unable to locate her. Then Sasuke discovers countless Sharingan embedded in Shin's arm. Following clues gleaned from Shin's arm, they come upon the laboratory of the heinous Hidden Leaf criminal, Orochimaru, who has been conducting research on Forbidden Jutsu. There, Sarada meets her father's former partners Suigetsu Hozuki and Jugo. She then asks Suigetsu to look into who her real mother is.

Boruto and his classmates head to the Village Hidden in the Mist in the Land of Water for a field trip. Kagura Karatachi is chosen as the village guide. About the same age as Boruto, Kagura is already an accomplished shinobi and serves as an aide to the Mizukage, Chojuro. Once known as the Blood Mist Village, it's now more modern and bustling than anyone could have imagined. However, dissatisfaction exists among some Hidden Mist Shinobi.

Tsurushi Hachiya, Kagura's former classmate at the Academy, finds Boruto and his friends from the Leaf irritating, so he kidnaps Denki. Kagura and Boruto set out to rescue him, and they find themselves in a battle against Hachiya and his crew. During the fight, the truth that Kagura has been hiding is revealed!

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!

Prior to the graduation exams, it's decided that the students will take part in a three-person interview to discuss their future plans. Boruto, who has passed his ninjutsu courses with flying colors, realizes his path toward becoming a "ninja" has been trouble-free and easy. As the students prepare for their finals, Boruto meets a journalist named Sukea who is doing a story on them. Something about Boruto's indifferent attitude about his future as a ninja raises a red flag in Sukea, and he gives Boruto a warning.
