Konohamaru’s cousin, Mirai Sarutobi, is assigned to escort the Sixth Hokage Kakashi and his friend Might Guy to the hot springs.

Mirai and crew arrive at the hot springs located near the border of the Land of Fire and the Land of Steam in time for a festival celebrating dogs and cats. But Mirai—always on the job—just can’t relax!

A few days into the mission, Mirai visits the hot spring with Tenten, Guy’s former student. But that moment of relaxation is interrupted by Guy yelling about a ghost.

Mirai, Kakashi, and Guy travel with Tatsumi to a village with a secret hot spring, but they find the hot spring covered by a boulder! Luckily, Choji drops in, armed with the Akimichi Clan’s Secret Super Expansion Jutsu, but he’s too hungry and can’t utilize the full extent of his abilities!

Moved by Tatsumi’s efforts to accomplish her goal all by herself, Mirai decides to help her even though she's still in the middle of her mission.

Mirai leaves the inn with Tatsumi without telling Kakashi and Guy. At the hot springs Mirai thinks she sees her father Asuma, but something feels off. Will Mirai be able to get back to her escort mission in one piece?

Naruto and Shikamaru deliberate on the results of the Chunin Exam that were left unsettled due to the Otsutsuki attack. Sasuke returns, looking for clues about the Otsutsuki Clan.

With Shikadai as captain, Boruto, Iwabe, and Wasabi form a special team for a mission to find and bring back a rare flower that only blooms for a short period of time. What should have been a simple mission ends up progressing slower than expected as the team continues to argue.

Extreme Ninja Cards, featuring famous shinobi from history, is the most popular game in recent times. As Boruto and his friends eagerly collect the cards, they realize they are still missing their former teacher, Shino Aburame, and Metal’s father, Rock Lee! They also learn that there’s only one space left in the upcoming series! A fierce battle begins between Boruto, who thinks it should be Shino, and Metal, who stands behind his father. Which candidate will make the final slot?

Kakashi goes to the post office—disguised as Sukea, a freelance journalist—to observe Team 25, whose mission is to assist with sorting mail. Houki Taketori, Hako Kuroi, and Renga Kokubou are genin and Boruto's former classmates. As a team, they haven't distinguished themselves, so the missions they are assigned to always consist of simple tasks. Furthermore, they lack teamwork. To find the reason for this, Kakashi decides to talk to Houki, who for some reason dresses just like him.

One day, Boruto and Konohamaru rescue Remon Yoimura from an attack. Remon says she has come to Hidden Leaf Village for sightseeing. Boruto and Konohamaru offer to show her around the Leaf and provide some protection as well.

Boruto and Konohamaru pay a visit to Remon's village, but are puzzled by Remon's cold demeanor. It turns out that Remon is a descendant of the Souma, a family that has protected the village from goblins for many generations. Thus, she is not allowed to leave the village freely. Furthermore, an important ritual is to be held shortly, so Kankitsu Akitsuki, Remon's childhood friend, imprisons her to prevent her from seeing anyone.

Konohamaru tries to rescue Remon by checking up on Kankitsu, but he is caught and forcibly taken back to the Leaf Village. Boruto becomes suspicious when he sees Kankitsu alone and acting as if nothing has happened. He decides to investigate the situation, only to be shocked by the sight that unfolds before him! Meanwhile, Konohamaru is disciplined by the Hokage after receiving a complaint from Remon's village.

Konohamaru and Boruto set out again to rescue Remon but find they’ve arrived a little late. Soma has broken the seal and begins his resurrection. Boruto and Konohamaru try desperately to stop this, but none of their weapons and ninjutsu work against him. Watching them, Remon is inspired to carry out her vow and employ the method her ancestor used long ago to seal the monster.
