Naruto Chapter 428

[Psyke]

Intuition should tell us that the Rasengan itself is not THAT hard to do. Difference is on how powerful and effective it can be when used by different kinds of people.

And as we've learned, the Rasengan is simply the first step of more powerful techniques.

Yeah, but a few years back the Rasengan, a class A jutsu or something like that, was such a big deal that Tsunade deemed it impossible for Naruto to learn (although it was just a week).

Nonetheless, considering that Konohamaru is deemed as a future Hokage candidate he should have some potential. But he needs to stop following Naruto's footsteps.
