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.

Kagura unlocks the storeroom to let Shizuma take the Mist Blades. The New Seven Ninja Swordsmen begin an insurrection, the end goal being to turn their village back into the Blood Mist Village! News of the rebellion reaches Chojuro and Mei, the current and previous Mizukage. They are determined to execute the perpetrators, along with Kagura, who aided them. In order to change Chojuro's mind, Boruto makes an astonishing announcement.
