How did Boruto learn the shadow clone jutsu? Who taught Boruto the shadow clone Jutsu? In the anime, episode 36 Kakashi asks if Boruto's father (Naruto) taught him the jutsu, but he replied no. If Naruto didn't teach Boruto, then who did?
I think it's most likely Konohamaru, as in Boruto the movie, before Sasuke takes Boruto as his pupil, he already knows how to preform that jutsu. And in Boruto episode 36, he states that his father didn't teach him the jutsu.
