Although it is difficult to learn, we have seen many shinobi master Sage Art after adequate training.
Below is a list of five Boruto characters who could use Sage Mode at some point in the future:
5. Uzumaki Boruto
Boruto is the main protagonist of Boruto: Naruto Next Generations and one of the strongest in the new generation of shinobi.
So, it wouldn’t be too difficult to see Boruto finally learning the Sage Technique.
4. Sarutobi Konohamaru
Konohamaru is the captain of Team 7, he is an extremely strong ninja and also has the goal of becoming the next Hokage of Konoha.
To fight and defeat them, Konohamaru will likely need to learn Sage Technique and develop it strongly.
3. Uchiha Sarada
The daughter of Sasuke and Sakura, Sarada is a talented kunoichi who aims to become Hokage in the future.
Sarada learns a lot from Naruto to become stronger and there is a possibility that she will learn Senjutsu from the Seventh Hokage.
2. Kawaki
Kawaki was introduced as a villain in the opening of Boruto: Naruto Next Generation, however, he is a quite interesting character in the current plot.
Kawaki has learned quite a lot from the Seventh, so in the future, Kawaki can also learn Sage Technique directly from Naruto.
1. Kashin Koji
A mysterious member of the organization known as Kara, Kashin Koji has been making more appearances since the Ao arc of the Boruto series.
Kashin Koji has a lot in common with Jiraiya, so it is very possible that he can use Sage Mode, he will probably learn about Sage Mode at some point in the story.
