Background

Boruto is the first child of Naruto and Hinata Uzumaki, receiving a younger sister Himawari two years later. As his parents continued to stay close to their childhood friends over the years, Boruto ultimately came to know the various parents' respective kids well.[3]

On the day that Naruto was to be inaugurated as the Seventh Hokage, his sister Himawari wanted to bring her panda toy to the ceremony, but Boruto, fearing that he would end up carrying it, tried to take it away from her. When the toy's head was ripped off in the ensuing tug-of-war, Himawari awakened her Byakugan and attacked Boruto in her anger, despite his vehement apologies. Naruto, sensing her killing intent, arrived and shielded Boruto, and was knocked out in the process due to the attack landing on one of his chakra points. Fearful of what an attack that could knock-out his father would do to him, Boruto tried to run from Himawari, although she easily located him hiding in a closet. From then on, he vowed never to anger her again.
