Boruto and his classmates head to the Village Hidden in the Mist in the Land of Water for a field trip. Kagura Karatachi is chosen as the village guide. About the same age as Boruto, Kagura is already an accomplished shinobi and serves as an aide to the Mizukage, Chojuro. Once known as the Blood Mist Village, it's now more modern and bustling than anyone could have imagined. However, dissatisfaction exists among some Hidden Mist Shinobi.

In order to get out of the barrier, Boruto desperately searches for his heart of stone, but he has little success. Then he encounters Sekki, one of the Genbu Three that participated in the recent Chunin Exams. Sekki has also come to the training ground in order to find his heart of stone. Seeing their predicament, Ohnoki tries to help them.

The Hidden Leaf established Parent and Child Day to allow busy parents to spend a day off with their children. Boruto and his sister Himawari await the day with anticipation. The day arrives, and Boruto is happy that his father was able to finish work and come home, so he decides to let Naruto spend all of his time with Himawari.
