Boruto pulls a prank and is pursued around the village by Naruto. Seeing this, Sarada can't help but be exasperated, but a part of her grows wistful as she thinks of her father, Sasuke, whom she hasn't seen since she was a baby. She begins to feel doubt after she sees a photo of Sasuke with a young woman wearing glasses. Sarada becomes determined to learn the truth. Will the secret of Sarada Uchiha's birth be revealed?!

Boruto and his classmates are invited to tour the Hidden Mist Academy under Kagura and Chojuro's escort. The Hidden Mist emphasizes swordsmanship, and Boruto is awed by their intense training sessions. Chojuro sees Boruto's interest and arranges a sparring match with Kagura, who seems hesitant. Kagura is extremely skilled and has been asked by Chojuro to become the successor to his Great Twin Sword, Hiramekarei, but he has declined.

Chojuro leads Boruto and Sarada to the location where Shizuma and his "New Seven Shinobi Swordsmen" are based. Shizuma uses his jutsu to create a fog that clouds the trio's vision, and they end up getting separated. Sarada is forced into one-on-one combat with a kunoichi, Buntan Kurosuki, who wields the Lightning Blade, Kiba the Fang! In the thick fog, Sarada uses her Sharingan, but her enemy is stronger than expected. Driven into a corner, she comes up with a counterattack. Meanwhile, Boruto goes up against none other than Kagura.
