Nami no kuni

Team 7 and Tasuna are watching, as Naruto has confront Zabuza again. And the strangest part is that Naruto unsealed a sword. One more thing stranger is that at the sight of the sword, Zabuza has freaked out. Then Naruto used Kirigakure no jutsu and hide himself in the thick mist.

"Strange" muttered Kakashi narrowing his remaining eye.

"What is strange, sensei?" asked Sakura looking at her sensei.

"Naruto's presence has completely disappeared. That's just impossible. Normally even if the person hides himself well enough, I would still be able to feel him somewhere. But Naruto has managed to hide everything. No fear, breath, footsteps, bloodlust even his chakra was hidden. It's the first time I saw this" said Kakashi with his eye open and looked at where Naruto stood moment ago.

"Well, I can't feel his presence either. Plus just from looking he had managed to perform Kirigakure no jutsu. Even my brother said that to completely hide yourself is impossible. But Naruto had surprised me and proved that the normal theories aren't for him" said Sasuke looking forward.

With Zabuza

Zabuza is looking around and try his best to sense Naruto's presence, but it was futile. No matter how much he tried he couldn't feel anything from Naruto.

"Tch, that brat even managed to learn the Kirigakure no jutsu just by observing. Though, he said that sword was his rightful heirloom. What is that mean?" muttered Zabuza on high alert, preparing for Naruto's attack.

Suddenly, he felt the wind changed at his back and so he slashed with his zanbatou behind. But it seems he missed.

Naruto then used Uzumaki sword style to slash seemingly randomly, which caused Zabuza to deflect the attacks on instinct. But he couldn't deflect all the strikes and was injured to the right shoulder and the hip.

Zabuza jumped back and panted tiredly. He glared at the silhouette in front of him. Then he formed handsigns.
"Suiton: Suigandan"

The silhouette sinked to the water below to avoid the attack. Zabuza has enough of this thick mist so he channel his chakra to Kubikiriboucho and spin around, to create a huge gust of wind enough to blow away the mist, revealing Naruto, that stood not far from him in calm expression.

With Team 7 and Tazuna

The mist has finally cleared and they could see what is going on now. Sakura beamed when she saw that Naruto was completely fine. That she looked at Zabuza and saw that he was injured in the right shoulder and the hip.

"It seems Naruto-kun is winning. It's so incredible! He managed to injure a jounin-level shinobi. Something which Kakashi-sensei even with Sharingan struggle with" exclaimed Sakura in awe.

"The question though. Where did he learn to wield a sword to such degree?" wondered Kakashi looking at Naruto.

"I don't know. Even though we were close, I didn't know that Naruto could wield a sword. Heck, I am sure even Itachi don't know" said Sasuke.

"Anyway, let's continue to watch this battle. I am sure Naruto will be fine" said Kakashi. His students nodded in agreement.

Zabuza vs Naruto

Zabuza looked at Naruto and saw that his face didn't changed the moment he casted the Kirigakure no jutsu. His eyes were still the same like of a dead fish. And he still can't feel his presence, even if Naruto is standing right in front of him.

"How did you do that, brat?" asked Zabuza curiously.

"How did I do what?" Naruto asked back cocking his head.

"Why can't I feel your presence even though you standing right in front of me? What kind of jutsu you are using?" demand Zabuza.

"It's simple. When the swordsman managed to reach The Realm of Nothingness, he could erase his presence. To reach that realm need to train to death. Not many swordsmen managed to reach this realm. But I am the only one alive that has managed to reach this realm. All thanks to my special condition. Those who managed to reach the realm were called Kensei. Did that answer your question, Zabuza-san?" answered Naruto and put the edge of his blade to his right shoulder.

Zabuza widened his eyes and recalled something. Long time ago, he has already heard about that term. It was said that only the one that trained to death and managed to overcome it will reach the realm. As far as he knows, from Kirigakure none of the Kirigakure no Shinobigatana nananin shu has reached that realm. And here this brat proclaimed that he is a Kensei. He won't believe him.

"That's bullshit! None of the Seven Swordsmen had reached that realm. And you, a snot brat, dare to declare something like that. I will kill you painfully for joking like that!" shouted Zabuza and charged at Naruto.

"It doesn't matter whether you believe me or not Zabuza-san. But I will prove you that I am talking the truth right away" said Naruto and intercept Zabuza with Nenekirimaru.

Zabuza began to swing widely and put much force in his strikes. Naruto just deflecting all the strikes with calm face, and even managed to kick Zabuza in the stomach.

Zabuza was sent behind, because of the kick. He gritted his teeth and formed chain of handsigns.
"Suiton: Suiryuudan no jutsu"

Naruto opened his palm and concentrated chakra in it.
"Suiton: Suijin no Tate"

A huge shield with a face appeared in front of the water dragon, deflected it.

Zabuza gritted his teeth and decided it's time for his trump card. Naruto's face never changed, but he felt that Zabuza was about to bring a big gun. So he also prepared for the counter.

Zabuza raised his zanbatou up with both hands and began to shout out loud while concentrating the rest of his chakra in it.
"KIRIGAKURE KENJUTSU OUGI: DAICHIZAN!"

Then he slashed with all the force he has to the ground creating a huge crescent wave that even split the ground. The wind blew harshly the moment he unleashed his technique.

With team 7 and Tazuna.

When they saw Zabuza unleashed that huge crescent strike, they began to wide their eyes in shock and worry.

"Naruto-kun! Dodge! Don't let it hit you!" screamed Sakura to warn Naruto with a terrified look on her face.

"The kid is doomed. The kid is doomed" muttered Tazuna while his knees shaking horribly.

Sasuke and Kakashi looked at Naruto and saw he was still calm.

'What will you do now, Naruto?' thought both of them in interest.

With Naruto.

Naruto looked calmly, as the huge crescent wave attack is heading to his direction. The wind blew harshly causing his hair to dance dramatically with the wind. Naruto brought Nenekirimaru in front of him and put two fingers to the edge of his blade, then began to trace it from the end to the tip. That action made his sword to glow crimson. He then slashed forward.
"Uzumaki ryuu: Satsujin ken-Mizuchi"

Naruto then disappeared suddenly with the wind.

Zabuza was surprised, as Naruto suddenly disappeared. Then it happened. He felt warm breeze envelope his body like a spring breeze. Suddenly, he heard a voice behind him.

"Can you hear it? The voice of the wind" muttered Naruto turning his head slightly to look at Zabuza.

Zabuza suddenly felt that he was bleeding profusely from the entire place on his body. His eyes was widen on shock at what happened. He couldn't understand anything at all. All he could do was gasped in shock.

"H-how?" muttered Zabuza before the two senbons struck to his neck. After that, Zabuza closed his eyes and seemingly dead.

With Team 7 and Tazuna

They were completely at shock when Naruto managed to destroy Zabuza's technique with a single slash. Then Sakura screamed loudly
"Yatta, yatta! Naruto-kun won! He really defeats Zabuza alone"

Sasuke then looked back at Naruto's back and muttered.
"Just how strong are you really, Naruto? How much did you go through to gain such strength? How can I keep up with you? I still even managed to unlock my Sharingan. So how am I gonna surpass you and Itachi?". Sasuke gripped his fist not in anger, but at how powerless he is compare to his brothers.

Kakashi just watching Naruto and analyzed.
"Such strength could only be gain through hellish training. Naruto was absent for a week in the past, but that amount of time is too short to reach this result. So how did he become so powerful? Even if he is a genius, he couldn't reach his level through personal training. Itachi? No, he was too busy in ANBU to help to train Naruto. But even he wasn't this powerful when he was Naruto's age. I felt that there was a huge mystery behind his strength"

Then they were surprised when Zabuza was suddenly struck by two senbons to his neck, which killing him instantly. They immediately reached Naruto and looked at who was the one that did that.

The culprit was a Kiri hunter-nin that has a long hair which was held in a bun, two long bangs framing his or her masked face.

Naruto began to pant and fall to his knee after all those techniques that he used. Sakura immediately reached him and support him to not fall to the ground. They looked at the hunter-nin wearily.

Kakashi then approached Zabuza and checked his pulse on the neck and found none. He then looked back at the hunter-nin.

The hunter-nin nodded his or her head then replied.
"I thank you. I had been waiting for the chance to kill Zabuza" and Shunshin to Zabuza's corpse.

"Judging by that mask, you are probably the hunter-nin from Kiri" said Kakashi looking at the hunter-nin.

"You are well informed, Kakashi-san" replied hunter-nin. He was about to take the corpse away before Naruto decided to say one sentence that made him startled.
"See you later, hunternin-san"

With that the hunternin disappeared in a twister. Naruto couldn't hold back anymore and fall to the ground unconscious.

Sakura saw that and immediately kneeled down and shook Naruto.
"Naruto-kun? Are you ok, Naruto-kun? Open your eyes, Naruto-kun!"
