In retaliation against Boruto and his friends for destroying Tenma’s mobile fortress, the pirates land on the Isle of Shipbuilders. Funamushi, a follower of the Funato Clan, attacks Kagura, hoping to capture him alive so that he can use him as a bargaining chip. Kagura fights back using the Hiramekarei—the twin swords that the Sixth Mizukage Chojuro entrusted to him—but Funamushi is a formidable foe. Meanwhile, Seiren appears before Boruto and torments him with her persistent attacks. Can Boruto find his way out of this predicament?!

As Boruto and the others ready their plan, they learn that one enemy unit is heading to the village ahead of the rest. Since they haven’t finished making preparations, the village will be in danger, so they hurry to evacuate everyone. Kagura worries that they won’t have enough people to fight. Just in case, he releases the curse placed on Buntan, Hebiichigo, and Kyoho, temporarily setting them free. Hesitantly, they agree to fight alongside Kagura and Boruto.

Despite children being present, Funamushi fights fiercely with disregard for the damage he causes. Meanwhile, Araumi is informed by his eldest son Isari that his adopted son Tenma has died in battle. With his daughter already hovering between life and death, he explodes with rage. He declares that he will be taking full command in the battles to come.

Araumi is furious about the loss of family members and many of his subordinates during the battles so far. He officially declares war against the Land of Water. Upon hearing this, Mizukage decides to fight him to the bitter end. As war between the Land of Water and the pirates becomes inevitable, Boruto is confused by Ikada’s decision to fight the Land of Water. He does everything he can to prevent any more casualties, and Sarada and Mitsuki assist him in his efforts.
