As soon as he got within reach of his dark half, the dark Naruto smashed an elbow in his face, only for Naruto to turn into a log. He reappeared behind his dark version and linked his fists together, hammering them down onto his head. However Yami Naruto blocked the other blond, crossing his arms over his head. He grabbed onto Naruto's wrists before flinging him over his back, making him hit the ground with a grunt.
Despite getting the wind knocked out of him Naruto managed to latch onto his dark half's hands, pulling him down as he planted his feet in the other blonde's stomach. With a yell Naruto pushed the dark one into the air. Yami Naruto flew several feet into the air, and as he started coming back down Naruto jumped up to meet him. The blond planted a fist into the dark ones face, using his chakra increase his strength and send the dark Naruto flying.
Naruto landed back on the ground while his dark half hit it with a loud crash. He watched as dust flew into the air, getting into a stance as he waited for his other self to come out.
The Yami Naruto did eventually, bursting through the dust and coming towards him at speeds greater than those that the blond could reach. They soon began to trade blows, smashing each other through buildings and beating and pounding away at each other. They began using the buildings and debris to their advantage, each one trying to gain the upper hand setting traps with exploding clones in the hopes of at least catching the other off guard. They used all the skills they possessed to beat the other.
Technically the two were completely even; they had the same skills, the same strengths and the same weaknesses. A battle such as this would normally have turned into a battle of attrition with two people who had the same strengths simply winning by wearing the other down. Technically the battle was dead even.
However Yami Naruto had the power of the cursed seal fueling him, his darkness feeding the seal and in turn the seal feeding his strength. For every one hit Naruto got in, Yami Naruto got in three to four more, pounding away at the blond, beating him to a bleeding mass of flesh.
Not that Naruto was about to give up.
Realizing his situation Naruto jumped back and went through several hand seals. "Fuuton: Renkuudan!" Naruto's cheeks bulged as he gathered air into his mouth; he hit himself on the stomach, launching a compressed ball of wind.
"Fool,"Yami Naruto sneered as he went through his own hand seals. "You can't beat me like that! Fuuton: Renkuudan!"He shot out his own ball of wind, intercepting the one Naruto shot. The two clashed in an explosion of wind.
Naruto grit his teeth as he jumped on a building, speeding through more hand seals. "Fuuton: Kaze Senbon!" Several dozen senbon made of wind appeared in front of him, before all of them shot towards the dark Naruto. As soon as they hit, holes appeared on him, only for Naruto to disappear in a burst of smoke.
The roof broke apart and Yami Naruto flew out of the new whole, smashing a fist under Naruto's chin and sending him flying. Naruto hit the edge of the roof before bouncing off before he hit the ground below. Yami Naruto jumped off the roof, forcing Naruto to roll out of the way as he attempted to stomp on the blond.
Continuing his roll Naruto pushed himself up and released a wind blade as he pushed himself into a corkscrew. Yami Naruto dodged and Naruto used that time to close the distance, punching his other half in the face. However he was sent sailing back when his dark counterpart exploded.
Naruto gasped in pain as he smashed through a wall, landing on his back and feeling several of the sharper pieces of debris stab into his back. He yelped in pain, rolling on his stomach in an effort to keep the debris from going any deeper.
"Hehehe, I told that you couldn't beat me," Yami Naruto smirked as he appeared before Naruto, stepping on one of the pieces of debris and pushing it into Naruto's back.
"AAAAHHHH!" Naruto yelled out, his back contorting as pain shot through his nerves. When his counterpart released him Naruto gasped for breath, trying to control the spasms that ran through his back.
"Hah…"Yami Naruto sighed, "Looks like I'm finally gonna get my freedom."He kneeled down next to Naruto, "Don't worry I won't kill you, that would be like killing myself after all. However, now you're gonna know what it feels like to be locked away, and you're not getting out."
Damn it! Why is he so strong! Naruto grit his teeth as he tasted blood in his mouth. He tried to get up only to realize his body wasn't responding; on top of that his vision was starting to get heavy. He's too strong… I can't beat him…
'Don't give up,'Naruto blinked as he heard a feminine voice enter his mind.
'W-who?'
'You can't give up.'
'But he's too strong.'
'If you give up he will destroy Konoha, and the precious people you have inside.'
'Precious people?'
"When a person has something important to protect, that's when they become truly strong."
'Haku… I can't give up now. What would Haku-chan think of me if I just let him win! All of my friends would die! Ojisan, Teuchi-Ojisan, Ayame-nee-chan, Anko-nee-chan and Ten-chan. I can't give up!'
'Then you must get back up and fight.'
'W-who are you?'
The voice giggled, 'You will know in time. For now let me help you.'
Naruto suddenly felt power coursing through him as a foreign chakra invaded him. It felt odd, familiar, Naruto felt as if he should recognize the signature somehow. He stood up as the energy began pushing the debris out of his back, catching the attention of Yami Naruto.
"If you think I'll ever let you go free you've got another thing coming," Naruto said with his hair shadowing his eyes, the smirk on his face being the only thing Yami Naruto saw, "Now I'm gonna beat your ass black and blue!"
Naruto shot forward faster than his dark counterpart could react, jumping in the air and smashing a knee into Yami Naruto's face. As the dark one stumbled back, Naruto came in grabbed his head and smashed Yami Naruto's face into his knee, over and over as blood began to splatter on the floor.
Yami Naruto managed to free himself by jabbing his counterpart in the stomach, however it did little more then give him a second to breathe before Naruto was on him again. Like the last fight, this one was completely one sided; only this time it was Yami Naruto who was on the losing side...
