For the uninitiated or forgotten, Missing Nin is a runaway ninja. These ninjas leave their villages without permission. Since each ninja has its own obligations, this action is classified as desertion when viewed from the eyes of the military. The perpetrators were also regarded as fugitives.
One of the characteristics Missing Nin is a horizontal stroke in a headband. This indicates the runaway ninja has rejected their home village. Some of the leading Missing Nin also have symbols like these on their headbands. An example is Itachi Uchiha.
After the groove Naruto Gaiden Sarada establishes the heart of wanting to become Hokage. Not so with Boruto. After the groove Boruto: Naruto the Movie Naruto's son actually sets himself to be the protector of the Hokage. The role he imagined was closer to Sasuke than his father now.
While Sarada idolized Naruto's style in the lead, Boruto further considers Sasuke cool. From here it is felt that there will be a role exchange in Konoha later.
An Uchiha will become the Hokage and lead Konoha. Instead, an Uzumaki will precisely be a protector from behind the shadows. The figure who sacrificed happiness and time to be with his own family to make sure his village and Hokage are safe.
Based on these differences of ideals, it seems that Boruto will take a tremendous sacrifice for the survival of Konoha. Further discussion can you check on the second page!
