In order for Kawaki to become a genin, it’s decided that he can take a special test that differs from the one held at the Ninja Academy. A D-rank mission is deemed to be equivalent, so Kawaki is assigned as an additional member. However, he is difficult to work with, ignores the need for teamwork, and acts on his own—giving his teammates a hard time while disrupting the mission!

Cho-Cho is injured in an attack by a mysterious ninja and the item that Mozuku had been holding is stolen. Captain Shikadai realizes that this was no ordinary guard mission, but one that makes them the targets of other ninja. He immediately decides to turn back toward home. But Kawaki feels for Mozuku, who was entrusted with the item that would save his people, so he ignores Shikadai's orders and pursues the ninja along with Mozuku. All alone, Kawaki faces a powerful enemy who uses a strange jutsu. Will he be able to protect Mozuku and safely return him to the Land of Calm Seas?

The new Team 7—with Kawaki its newest member—is assigned to escort Katasuke to a ceremony in the Land of Water. Boruto is looking forward to seeing Kagura Karatachi, a shinobi from the Land of Mist whom he hasn't seen since their Academy field trip to the Land of Water. However, in the shadows of the ceremony, a group harboring a grudge stealthily begins to make its move.
