Naruto vs Sasuke first fight part 2...

Konoha…

Shinobi Academy…

Taijutsu training field behind the Academy…

After getting yelled at by Iruka Sensei Naruto and Sasuke both decided to make the "reconciliation" sign though they don't want to do it at first after all this would prove they recognized each other as a worthy opponent. 

In Naruto's case, he made the one-handed sign because he respected the rules and the history of the Shinobi world which made him think otherwise. 

As for Sasuke, he did the "reconciliation" sign with Naruto because he saw Naruto making the sign every before he made his decision and if he doesn't make the sign doesn't that mean he is acting like a child and decided to make the sign quickly and finish the fight.

After both of them made the single hand sign their teacher Iruka felt satisfied looking at his students following the traditional shinobi way and making the "reconciliation" seal raising one hand Iruka gave them a satisfied nod with a smile on his face and decided to give permission to start their spare "Begin~"

Naruto Uzumaki ⚡ Sasuke  Uchiha

Boom~

The moment Iruka's voice fell the two moved against one another with full speed.

Naruto knows that the current him is not a match for the Uchiha kids Taijutsu as he clearly knows Sasuke is an expert in Uchiha clans Taijutsu style while he knows nearly nothing about Taijutsu, after all, no thought him Taijutsu in all this year's and Shinobi Academy's teaching just forget about anything like that. 

As for his time on Earth at that time, he never needed to do anything related to fighting by himself, after all, he just needed to call him henchman and all things got solved by them with a little sum of money without him lifting a single finger.

Without any basic experience or skills, he is really going to get himself bet up by Sasuke but that would be if he was like the normal Naruto from before but now he is not just Naruto something more after the fusion of souls. 

And he now has a lot the understanding and knowledge of both of them together. As such he also got Naruto's memories from the academy which is a good thing for him after all the previous Naruto was really diligent with his shinobi life, after all, nobody was there to teach him as that needed to work hard by himself. Even though he never got lessons on Taijutsu from someone on personal bases but he still tried his best to learn from the older generation by looking at them practicing from afar in the academy then practiced it by himself when he is alone. 

Even if he never learned anything good by looking at the previous generations he still made his own set of Taijutsu techniques even if the technique isn't perfect still he needs to use what he got win or try to at least remember beggars can't be chores, and there is also there is the two no Seal Jutsus he developed after fusing with old Naruto which gave him his confidence to not getting trashed up by Sasuke.

After making his calculation clear he decided if he fights with normal means it will only be foolishness and torturing his own self and a cunning smile appeared on his face because he has already decided on his next move even before they came in the range of attack.

Sasuke, on the other hand, knows that Naruto doesn't know any taijutsu style after all unlike him Naruto didn't have anyone to teach him to begin with. As such he moved toward Naruto with no worry but once remembering his family his mode became even glummer as he decided not to let Naruto go easy after what happened till now.

When the two of them arrived in the attacking range Sasuke used his Uchiha style super punch on Naruto aiming at the face without showing any mercy.

As for Naruto, he wasn't able to read Sasuke's movements with his only eyes and almost got hit but  he is not fighting fairly and using his no seal jutsu "Map" to make his surroundings like a reader which gave him the location of Sasuke's attacking point and he easily avoided Sasuke's punch like how fish acts in water when getting attacked even without looking and caught Sasuke's hand then used no seal "Flight" to make a backflip oven Sasuke's head while not letting go of his hand which brought immense pain in Sasuke's hands but still things are not finished because he decided to kick Sasuke on the back with all his might using "Fight" in mid-air for a brief moment after going behind Sasuke without landing on the ground. 

The moment Sasuke punched at Naruto he didn't feel the expected friction from his punch on Naruto's face and understood he missed his target somehow then before understanding what is happening as an unexpected pain started spreading in the hand he used to punch at Naruto as if someone is trying to break it and before he could make the decision for his next action he felt something hitting him from behind as he saw the ground coming closer to his face and heard a loud boom upon landing on the ground spreading dust smoke in the ring.

Outsiders perspective… 

A moment after Iruka's signal of beginning the sparing everyone heard a loud boom from the ring when Sasuke and Naruto arrived at the range of collision and the ring got covered by dust screen as everyone stopped shouting by the sudden event in front of them.

As they waited patiently the dust smoke got cleaned away very soon as everyone saw Naruto sitting on Sasuke's back while bending Sasuke's right hand on his own back.

"So fast??? "

"What happened? "

"How did Naruto… "

"Am I seeing things… "

"No way…"

"How could this be…"

This kind of sounds started coming from the crowd as everyone is surprised by what they are seeing in front of their eyes.

"Let go of me, you loser? " Sasuke who is under Naruto's shouted angrily trying to free himself after undergoing what is going on as both surprise and anger appeared on his face with pain in the mix.

"Who are you calling looser you weakling? " Naruto said pressing his legs against Sasuke's back with more force as he didn't like how the kid talked with him.

"That's enough let go of him Naruto. " Iruka stopped Naruto when he saw Naruto using more force after getting out of his daze with Sasuke's painful growing while thinking 'How did Naruto avoid that punch at the last moment and the kick from behind??? '

After getting Iruka's call Naruto let Sasuke go and jumped back to his previous place with a smug face looking down at Sasuke who is still on the ground.

After feeling the weight on his back going away he got up from the ground then he looked at Naruto with anger and rage while dusting himself clean while thinking 'I was too much overconfident and didn't take him seriously but I still refuse to believe him to be stronger than me…'

'I really overestimated him. ' Naruto thought looking at Sasuke.

"Ok do a Unison sign you two. " Iruka said with a nod when Sasuke stood up from the ground to finish the spare officially.
