Boruto's classmate, Metal Lee, is very dilligent and is skilled at taijutsu. Unfortunately, he gets nervous easily and is unable to do his best when people are watching him. One day one of his classmates, Shikadai Nara, says something that enrages Metal, who attacks Shikadai the next day. Caught in the middle, Boruto notices that Metal's chakra is warped, just like Denki's.

Boruto, Shikadai and Mitsuki arrive at the location they are told to go to by Shino. They notice their teacher is acting different than he usually does— and Shino suddenly attacks them! Shino belongs to the Aburame clan, a clan of Insect Users. He unleashes a swarm of Parasitic Insects. Boruto and the others can't match the skill of someone who's a jonin. But even in this situation, Mitsuki remains calm and coldly stares at Shino.

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.

After Mitsuki reveals more information about the Ghost incidents, Boruto is determined to find and stop the culprit! Meanwhile, Seventh Hokage Naruto and his top advisors are shocked to learn who the perpetrator is from the results of Sai's investigation. Just then, Nue—an enormous otherworldly beast—appears! The imminent danger to the village forces the Sixth Hokage, Kakashi, out of retirement!

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.

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.

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.

In order to get out of the barrier, Boruto desperately searches for his heart of stone, but he has little success. Then he encounters Sekki, one of the Genbu Three that participated in the recent Chunin Exams. Sekki has also come to the training ground in order to find his heart of stone. Seeing their predicament, Ohnoki tries to help them.
