Konohamaru is one of the oldest characters from the Naruto in the sense that he has been in it since the very beginning however, he didn’t really get the screen time that many of the other Ninja’s who befriended Naruto got.
The only times we see Konohamaru really do anything in Naruto is during Pain’s raid, when he defeated one of the Six Paths of Pain.
But we must also remember that Konohamaru learnt the Sexy Jutsu, the Shadow Clone Jutsu and the Rasengan, a lot faster than what Naruto did. Yet due to his young age, he was quite irrelevant when the fourth Great War began.
However, things are about to change in Boruto, as the grandson of the third Hokage is now a jounin, as well as the teacher of Boruto’s team.
The only issue is we still haven’t seen enough from him to determine his strength, as so far the Boruto series is focussing on the children.
Yet we must assume that Konohamaru is quite strong and even possibly be able to use Toad Sage Mode. Rememeber Konohamaru has a great deal of natural talent and is a jounin ninja, which is not something any weak ninja can achieve.
Konohamaru also wishes to be the 8th Hokage after Naruto steps down, how can he do this as a regular ninja? The answer is he can’t so he must have something special up his sleave.
The reason I believe Konohamaru may have learnt sage mode is due to him not only being the student of Naruto, but also because of what he has shown us in the Boruto episodes so far.
Konohamaru has been seen summoning giant toads from Mount Myoboku, which means he already has an affiliation with the toads. His own personal toad is called Gamagoro, and I assume that he has other toads that he can call on as well.
We must also take into account that the only others that we have seen summoning toads are Jiraiya, Minato and Naruto who can all use Toad Sage Mode.
As Konohamaru throughout the Naruto franchise has copied Naruto during his childhood, it is plausible that he has continued to do so well in adolescence.
With Konohamaru’s large ambitions and obvious potential, it is extremely possible that he has already learnt this and is one of the most powerful jounin in the village, as Kakashi was a the start of Naruto.
