Naruto Swings his Staff down at Zabuza who is Able to block with his Sword just Barely before getting hit by his staff.
"That's one strong swing ya got there brat!" Zabuza says grunting from the pressure Naruto is exerting from his Staff. Naruto just grins and Nods in thanks before forming a Katana with one of his Truth-Seeking balls and Slashing at Zabuza who is Blocking his Staff. Naruto just Barely Connects, cutting Zabuza along the Arm and as he does Zabuza Jumps backwards away from Naruto and his Staff.
"So you want a Sword Fight Eh? Well Bring it on Brat!" Zabuza says Charging Naruto whose Staff had Turned back into a Truth-seeking Ball and left him only with a Katana while one of his Truth Seeking balls had Turned into Armor around his Chest and Stomach.
"Bring it on!" Naruto says Charging at Zabuza with his Katana.
'That Stance' Zabuza Thinks while they both Charge at each other.
'The Stance of God' Naruto thinks as his eyes glow for a second once he finishes thinking. Finally Naruto and Zabuza Clash and jump back immediately after. Neither of the Two Swordsmen Notice how everyone is watching on in shock that Naruto is Keeping up with a Member of the 7 Swordsmen. Naruto creates Two Shadow Clones and The Real Naruto charges and Distracts Zabuza while the Two Clones sneak behind Zabuza.
"Zabuza this is your End!" Naruto says, forming a Second Katana and Slashing Zabuza Across his chest.
"Agh! Damn It!" Zabuza Yells, not Noticing the Clones Making seals behind him.
"Lightning Style: Lightning Arrows Jutsu!" A Clone behind Zabuza says Catching his attention while Fifty Lightning Arrows fly at him at Jonin Speeds.
"Oh Shi-" Zabuza gets cut off by the Roar of a Dragon and Sees a Fire Dragon speeding at him. Zabuza Runs through hand signs as quick as Possible and Creates a Large Water wall.
"Water Style: Water Encampment Wall Jutsu!" Zabuza says as the dragon hits it creating a large amount of Steam and he is able to dodge the arrows. Finally everyone else snaps out of their shock and begin to fight against Haku. Naruto runs through the steam with his Two katanas ready to kill if need be. Realizing something he stops and holds out his hands, releasing a pulse of Gravity all the Steam gets blown away. Naruto and Zabuza rush each other again preparing to end it with one final Strike. Naruto's Swords return back into Truth seeking balls.
"Animal Path" Naruto says, summoning a Red and Black dragon with eyes as the Rinnegan and Naruto says one word that scares even Zabuza.
"Kill" And the Dragon speeds at Zabuza with High Jonin Speeds and bites into his chest, one of its teeth going straight through Zabuza's Heart, killing him.
"It was a Good Fight Zabuza… even though it wasn't Naruto fighting" The Cloak of the Sage of Six Paths disappears and his Horns Protrude back into his Head and he Collapses into Unconsciousness.
(In Naruto's Mind)
"Good Job Asura! You kicked his Ass!" Naruto says in Excitement.
"Thanks Naruto, But know that your Status is going to Rise as a Ninja once word gets out that 'You' Killed Zabuza and even though it was me, It was your body so people though it was you" Asura says, rubbing Naruto's hair.
"Kit you are currently in a Coma and I Healed your Body just enough to where you will Wake up in Two days, By teh way you should try to change the way your mind looks, it's your mind you can make it look like Anything" Kurama says. Naruto just nods before getting in a Meditative Stance. After a while the Sewer Begins to Morph and Warp until the Only thing that's left is A Giant green Meadow from Kurama to walk around in, A Giant forest, 5x Larger than the Forest of Death, a Few Mountains in the Distance and a Giant Mansion for Asura and Naruto to live in when he come to his Mind.
"Kit This is… Amazing… Thank you" Kurama says before going to explore the new Landscape.
