>The nemesis of the protagonist of the previous arc trains

Because "protagonist's son" is really rare in the first place, and even more so one that gets old enough to actually be an active player, but his father still continues as the protagonist.

I havent seen Boruto, but do something similar happens there?

>>160246406
That's a character arc not a trope

>>160246406
Most protagonists either never get old enough to have children or their nemesis is dead by the time they do.

>>160246406
Boruto the movie.

>>160246406
Because it's wasted potential just like Gohan.

Damn anon, why you got to be like that?

In the movie Sasuke does mentor Boruto a bit, idk if it goes further than that though.
