Kokuyou confronts Boruto and the others. Kokuyou, whose only goal is to become strong, is so powerful that he's taken down the Leaf ninja pursuing Mitsuki. He easily drives Boruto and his team into a corner. Just then, backup appears. Boruto and his friends manage to overcome Kokuyou, and finally catch with up Mitsuki.

Boruto is injured, unconscious and unable to continue. Everyone thinks about returning to the Hidden Leaf. However, being close to the Land of Earth, a surprise attack is highly possible. As a precaution, Inojin and Cho-Cho set out on recon of the surrounding area.

Boruto and Ohnoki head to the rendezvous point, but they stumble into the Hidden Stone Shinobi Training Grounds, which are protected by a barrier. Ohnoki tells Boruto that the only way out of the Training Grounds is to find his heart of stone, something that can only be found once in a lifetime when a person comes to terms with their will.
