[Anime] Naruto

Um, I think you two forgot what Kakashi said right at the start of Naruto: Shippuuden (Naruto Season 2)...

Spoiler:

...Kakashi was eager to show Naruto a brandnew jutsu. And I'm kind of sure that it's a lightning based jutsu, which he will use to burn the both to ashes. Who knows, maybe it's even some new Mangekyou Sharingan skill?

Jam it back in, in the dark.

About the end of Chapter 337...

Spoiler:

So, Naruto finally shows the power of Fuuton ("wind element", meaning that he completely mastered the jutsu) Rasengan, with the water element added by that Hokage clone (can't remember his name). Interesting, but I wonder if Naruto will eventually learn to use a second element, like Sasuke. Since otherwise Naruto has a big weakness.

There's nowhere I can't reach.
