The Land of Water is taken over by pirates, and contact with Denki's Team 5 is lost. The new Team 7 joins up with a unit led by Kagura and sets out for Dotou Island to assist Team 5 and rescue the islanders. However, the unit is made up of Buntan, Hebiichigo, and Kyoho, who in the past had called themselves the “New Seven Ninja Swordsmen of the Mist.” Sarada and Mitsuki go ashore to scout the island while Boruto and the others stay back and watch the situation nearby.
