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.

Boruto and his classmates decide to go camping to try to catch the mysterious fish, the Eternal Carp, said to be unforgettably delicious. With graduation coming up this could be the last time the class does something together, so Boruto figures this is the perfect opportunity to catch one, but the fish proves to be very elusive.
