Sasuke watched as the Leaf Village burned. His vengeance had come upon the monstrosity. His entire clan's blood was on the hands of the Leaf Elders. The black flames were visible from the Mountain. The blood of the Uchiha was the downfall of the Leaf, as the amaterasu did its job. Blood poured down Sasuke's cheek.
He swung around and punched the incoming hostile in the face. He looked and saw the very familiar sight of Uzumaki Naruto. Naruto looked up at Sasuke, the nine-tails chakra manifesting three tails. Hatred burnt in Naruto's eyes. He spat the blood conjured by the blow onto the ground.
"Why? Why did you destroy the Leaf?" Naruto asked calmly. Sasuke watched the tears stream down his face. Then he saw why, the charred remains of Haruno Sakura were on a tree branch. "How could you Sasuke? You monster, you will pay Sasuke!" Two shadow clones appeared, the nine-tails charka emanating from the three figures.
Sasuke looked at Naruto with sympathy in his eyes. He had insured that Uzumaki Naruto felt true hate, by destroying the Leaf. By exacting revenge on the Leaf, he had awoken a part of Naruto he has never seen. One of the nine-tailed clones attacked Sasuke, while the other helped Naruto do a jutsu. Sasuke dodged a punch, and kicked the clone in the face.
"I have to ask you Uchiha Sasuke! Are you really the last of the mighty Uchiha clan, or a cheap imitation who feeds on hate?" Naruto asked. The shadow clone burst away in a cloud, and the other burnt had already dispersed from the kick. Naruto held what looked like a Rasen Shuriken, but was blood red like the chakra surrounding Naruto. "Prepare yourself, for the power of true hatred! Nine-tail Rasen Shuriken!" Naruto ran forward, and threw the chakra ball at Sasuke with immense strength.
Sasuke lifted his hand, and held it in front of him. Lightning sparked in his hand, and then formed a chidori. He activated the black flame, and it mixed with the Chidori. Sasuke continued to hold it at the incoming Rasen Shuriken. Sasuke smiled. New blood oozed down his cheek covering the dried blood from the earlier use. "Uzumaki Naruto you will never be a match for me. Black Chidori!" he watched Naruto's smug expression, change to surprise.
Then Sasuke did a back flip, a trail of black flame following behind, and when he landed flung the Black Chidori at the incoming Rasen Shuriken. The collision was destroying the forest around them, and Sasuke enjoyed it. "There's no Kakashi to save you this time Naruto!" Then he did the hand signs and shot a full powered Fire Ball Jutsu at the Black Chidori to make it more in his favor. A smile crossed his face.
