(This is my first Naruto fic, but I have been a fan for many years)
Everyone approaches the sealed doors to see that Usuigi is pounding his fists against it to no avail. Sasuke starts towards the upper door that leads to the roof so that he can sneak out and hunt for Itachi.
All see that Usuigi has mutated further by now having a disgusting black substance instead of saliva falling out of his mouth and his hair was now a bright white. Tsunade winds up and punches the sealed door with everything she had. The seal and the door shatter, sending Usuigi and some of the other ninja flying through the air and landing on their backs. Shikimaru and Chouji jump out and start killing any fallen ninja with their kunai. Tsunade and Naruto charge the fallen Usuigi but they see black gas billow out of Usuigi's mouth and they quickly back off. When the fog clears, they find no Usuigi. Suddenly Naruto feels a punch collide with his back and sends him crashing into a wall.
Tsunade charges the demon Usuigi and starts throwing punches at Usuigi's face. He dodges her punches with near ease. Usuigi suddenly grabs Tsunade's hand and punches her right in the stomach with his other hand, sending he flying back about ten feet. Usuigi forms seals at supersonic speeds and lightening burst from his fingers, destroying the outer layer of the tower. Sakura charges forward and attacks but to no avail like her mentor. Usuigi forms a chakra scalpel out of black chakra and slams it into Sakura's chest, sending her to join her teacher in the rubble.
Naruto sees this and forms about 40 clones. Usuigi stares at all of the charging Naruto's and smiles that sadistic smile. He forms the same seals at the same extreme speed and lightening impales multiple clones, destroying about half of them. He forms more seals and the ground beneath the clones rises at a high speed and crushes them from beneath, destroying even more. Naruto realizes that he has lost almost 30 clones already. He sees the black needles fly out of Usuigi's mouth. He has a clone pull him out of the way just in time to avoid the needles, which destroy the rest of the clones. Naruto gasps for breath. He had just completely wasted some of his chakra. The clones will not work against Usuigi. Usuigi looked like an evil king with his black cloak and white hair. Naruto dodges more lightening and tries to come up with a plan. He knew that long range tactics would not work against a man with such knowledge on ninjutsu. He had to get in close and hope that Usuigi wasn't as skilled in taijutsu. Naruto jumps onto the roof of a nearby house. Usuigi glides the same roof with one powerful jump.
Tsunade and Sakura are healing themselves when they see Naruto and Usuigi on the top of a house, staring at each other. Konoha's past and Konoha's future about to battle it out. Naruto and Usuigi charge each other. Naruto throws vicious punches and kicks, which Usuigi dodges and jumps out of the way and lands on the roof, denting it. They both pull out kunai and charge once again. There is a clang as the kunai collide. Each man trying to get the upper hand but can't. Naruto forms 3 clones and has them all charge him. Usuigi forms seals extremely fast and suddenly all the Naruto's are sent flying.
Tsunade saw what happened, it was an absolute defense. A sound wave came out of the pores in his skin with extreme force and slammed in Naruto. Suddenly she sees something blur past her and up to the roof. It was Kakashi. He ran in front of Naruto and began to form seals of his own at an extreme speed. Fire bursts out from Kakashi's mask, engulfing Usuigi. All of a sudden, water emerges from the flames, and smashes through buildings, colliding into Kakashi, sending him into a wall. Naruto sees this and charges while throwing shuriken. However, the next thing he sees is Usuigi catches them and throw them back and perform his shuriken cloning technique. Naruto jumps away but one shuriken gets lodged in his calf. Naruto reaches inside and pulls out the shuriken, which fades away in his hand. Though the shuriken was an illusion, the injury was real. Naruto jumps over to a recovering Tsunade, who heals him the best she can. Everyone sees Usuigi charging with lightening covering his entire left hand. All of a sudden, Kakashi with his own Lightening Edge, blocks Usuigi's attack with his own and delivers a fierce kick to Usuigi's gut. This sends Usuigi to the ground for the first time. He and Gaara are side by side and see Usuigi get up. His golden eyes are twitching in anger. All of a sudden, Usuigi smashes his fist to the ground and the ground starts to crumble. They both dodge and Gaara sends his sand shuriken, which collide with Usuigi's chest. Usuigi falls to one knee and Kakashi follows up with a fierce uppercut to Usuigi's chin.
Kakashi sees that Usuigi is growing incredibly irritated. All of a sudden they both see Usuigi form seals that Kakashi knew only too well. Kakashi didn't have the amount of chakra that would be required to drown the fire clone. They see the black flame burst out of the Sanin's mouth and they both dodge it.
"WATCH OUT GAARA!" Shouts Kakashi as the fire clone forms and lunges at Gaara with clenched fists of black hell. Gaara's sand shield forms to block the attack, but the fire incinerate the sand and Gaara gets punched right on the jaw. Gaara feels the entire right side of his face feel as if was ripped right off. He screams and falls to the ground. Kakashi sees this and knew what he had to do. He activates his Mangekyo Sharingan Eye.
