now we know for sure resengan> kirnin (spelling)

Kuuton?
lol, ok you mean Fuuton.
True, but Naruto would have to make the RS before the Kirin comes at him

Let's look at it like this:

Kakashi himself said that pure chakra attacks are much stronger when they have both shape recomposition and elemental recomposition.

Chidori is lightning chakra in the shape of a sword. It's got both shape and elemental recomposition.

Rasengan is a ball of raw chakra. It's got just shape recomposition.

Rasengan is stronger than Chidori, even though it doesn't have elemental recomposition.


And Kirin is just raw lightning. It's not particularly strong, it's just virtually unavoidable. All of these attacks (Chidori, Rasengan, Kirin) could kill you on one hit.

In that sense, Kirin's not much stronger, in plain old power, than Chidori. While I wouldn't go so far to say that a plain old rasengan could stop Kirin, I would say that a Kuuton: Rasengan would. And if that's true, a Fuuton: Rasenshuriken would definitely stop Kirin.

You definitely got it right... chidori is the combination of shape and nature... what would chidori look like if the same shape manipulation was used with fire or wind? Its just a completely different use of form manipulation that rasengan...
Rasengan is the ultimate form of shape manipulation... any nature manipulation to that... makes the technique the ultimate chakra technique for that element... period...
