Naruto and Sasuke battle..

After a failed attempt at assassinating Danzo.Taka (鷹, Hawk) team were on the run (approx. a few days) However when Karin says she senses someone with an enormous amount of chakra headed towards them. Sasuke tells her to stay there and heads of in the direction of the chakra source to meet head on with Naruto.

Sasuke: Ah. So it's only Naruto.

Naruto: Sasuke! You've gone to far. First joining Akatsuki and going after someone like me, and now you're attacking a kage! You're no better than Orochimaru or Itachi!!

Sasuke:I don't care what you have to say Naruto. I have my reasons for attacking Killer bee and Danzo, and I don't need a weakling like you questioning them!

Naruto: Sasuke!- *Naruto lunges after Sasuke with a small blade in hand*
It looks like I have to choice but to use force to get through to you.

Sasuke: Ha! Just because you defeated Pain doesn't mean you can beat me now Naruto
*Sasuke activates his Sharingan pulls out his sword and blocks Naruto's attack*
sasuke:You've gotten a little faster since last time but you still haven't learned.

Description: A lightning jutsu that is concentrated in the user's palm and thrusted toward the opponent at high speed. The lightning in the user's palm sounds like birds chirping, hence the name.[/JUTSU]

Sasuke's Chidori flows into his sword and he tries to cut through Naruto's blade but it doesn't work due to the wind chakra flowing through it and instead his sword chips a bit and so he backs a way and begins to throw kunai and shuriken at Naruto however Naruto knocks them all away. Then he does on of his oldest tricks using strings attached to the kunai to wrap around Naruto and ignites them, but Naruto cuts the strings before the flames reach him and charges forward and Sasuke. Sasuke try's to block the attack with his sword but it is sliced in half and he is forced to back away

Sasuke: So it looks like you do have some new tricks Naruto but

he lets go of the sword and does some hand signs

Type: Offense/Defence
Range: Short
Chakra Cost: 30
Damage Points: 60
Description: This jutsu allows the user to generate non-focused electrically charged chakra from their body. Because the electricity isn't focused, it doesn't kill on contact, instead it only paralyzes. The lightning can be channelled through metal objects, as well as spread out into the air or ground.
[/JUTSU]

The lightning chakra spreads around Naruto and he jumps back dropping his blade

Naruto: Keh! Then lets try this

Naruto forms his signature hand sign -kagebuunshin no jutsu- Naruto makes two clones, two Naruto's go to the side and the third goes through the center for a simultaneous attack from three sides,

but Sasuke sees this coming and jumps in the air before they can get. However Naruto expects this, and we see him forming a Rasengan with his clone which he then jumps up on- Rasengan.

Sasuke:Cheh! This again. Chidori- The Chidori and Rasengan clash while the two are in mid air causing a small explosion sending the two flying in opposite directions. Sasuke's braces himself and crashes into a tree while Naruto is nowhere in sight- Agh. I can't believe I let Naruto do that to me. Sasuke gets up and looks around to try and find Naruto when Naruto comes jumping down.

N-Oodama Rasengan- Naruto pushes the Oodama forward at Sasuke.

S-Kah!- Sasuke kicks off of the tree and the Oodama collides with the tree breaking it where it collided and causing it to knock over a tree right next to it and the Clone to burst- in the middle of the air to himself Sasuke thins "If that had hit me. Looks like I'll have to get serious, but I really didn't want to have use the MS so soon after I last used it."-Just as he finishes his thought we see Naruto again this time with two clones beside him forming a Fuuton Rasengan Shuriken.

N- the sound of the chakra being formed fills the air while Naruto who we can see is in Sage mode thinks to himself "If I just reduce the amount of chakra and control it enough this shouldn't kill him!"- Right after this though he fires it off towards Sasuke.

S- Sasuke activates his MS and stares and the oncoming FRS-"Amaterasu"- The black flames engulf the FRS and it begins spinning releasing all of the wind chakra and causing the flames to grown into one giant fireball of destruction- Kah!- Sasuke gets blasted back.

N- Ahh- Naruto jumps back barely avoiding the flames.

S- Panting Sasuke looks around the cleared out portion of the forest to see if Naruto is there, but all he can see is scorched land and forest being burned by the black flames- You see Naruto this is the power given to me to get my revenge, to express my HATRED. This is what Itachi gave to me, this is something not even you who couldn't even kill Pain the man who killed your precious Jiraiya could never achieve.- From within the forest there is silence, but soon there is a rustling and Naruto steps out bruised, scratched, and in somewhat bad shape.

N- No!- Naruto flashes back to his encounter with Itachi and remembers his tone and way of speaking- Sasuke Itachi wouldn't have wanted this because I know he must have known revenge and hatred only brings more revenge and hatred. Even after Itachi's death and the Raikage's attack on you can you not see that?- Naruto braces himself- Even though I didn't really want to go so far as to fight all out, guess I will have to show you that friendship and perseverance are what really bring power
