The Academy's school festival has finally begun. At the school festival, a large number of people, including Boruto and other graduates, gather and are very busy. Meanwhile, the other day, Kawaki, who had an encounter with someone who seemed to be an assassin aiming for Kae, was worried about it, but he worked hard at rehearsals with his classmates for this day, and was looking forward to today's performance. Looking at Kae who is doing it, I decide not to report the assassin for the time being and watch over Kae so that she can enjoy the school festival to the fullest. However, a sudden bombing incident occurs at the academy, which is crowded with people, and a threatening letter arrives from the criminal.
