Preview of the next episode (from the official website: https://www.tv-tokyo.co.jp/anime/boruto/episodes/):
The rebellion of pirates that shook the Land of Water is over, and Boruto returns to Konohagakure no Sato (Village Hidden in the Leaves) with his friends, but he is concerned about what will happen to Buntan. There is still no decision made on how to deal with Buntan. Although Buntan and the pirates were to fight against the Land of Water, Boruto asked for lenient treatment, and Kawaki, unlike Boruto, said that severe punishment was inevitable, and the two fought. While Boruto is thinking about the people involved in this battle and what Kawaki has to say, his father Naruto speaks to him.
