Kawaki starts to believe that being a genin is not for him. The Seventh Hokage gives him a last shot and assigns him to join Shikadai and Cho-Cho on a mission to protect Mozuku, from the Land of Calm Seas, and escort him back to his homeland. Will Kawaki be able to cooperate with his comrades and fulfill the mission this time? Meanwhile, Team 7 is on another mission and they pass a group who seem to be ninja in disguise…

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?
