During the protests, the Byakuya Gang attacks Katasuke's research center, which has been developing new technology for Scientific Ninja Tools. Shikadai figures out what the Byakuya Gang's goal is and rushes after them in pursuit with Boruto close by. Even a weak "pawn" can become strong in one move—what are the two friends who bonded through shogi seeking?

Team 7 enters the mine where the thieves had been hiding out, only to be attacked by a powerful, strange-looking White Zetsu. They find out the mine connects to a ruin belonging to Kaguya Otsutsuki. Team 7 decides to investigate and engage the White Zetsu. As they proceed deeper and deeper into the mine, they make a shocking discovery!

The final battle of the tournament begins with Boruto, Sarada and Shinki participating in a battle royale. As the lone representative remaining from the Hidden Sand, Shinki is determined to preserve the pride of the Sand, and goes on the offensive against Boruto and Sarada. Boruto and Sarada team up to fight Shinki, but he puts up an impenetrable defense. Sarada falls, and Boruto's chakra is nearly exhausted, but he refuses to give up!
