Naruto vs Kisame

Sasuke's residence

Kuro explained to sasuke what happened on his way to the summit. How danzo died by his hands and that there were sharingan eyes all over his hand which was normally covered with bandages. That he plans to implant one of the eyes himself just like kakashi did. And that he is giving him back the remaining eyes that danzo had stoled from their clan. But to his surprise Sasuke's reply was a little different from what he expected.

"Sensei you don't need to give me those eyes. They're yours now since you defeated danzo yourself. What I want to know more is that since danzo is no longer alive. Do you think there's a chance for us to bring him back to the village?" kuro was surprised that Sasuke doesn't care about the eyes and is actually more worried about his brother. 'damn, I might have changed him a little bit more' kuro paused to think how to reply.

"Hmmmn... It might be possible. All we have to do is ask the current Hokage and also the former. The only problem we have are the remaining elders of the council but I don't think they can stop the fifth if she makes a decision and learns the truth about it all." kuro explained truthfully. Sasuke nodded. So they planned on what steps to do next so that they can bring itachi back to the village.

A few days later

Kuro along with Naruto, Sasuke and Sakura were dispatched to bring itachi back to the village in a discreet manner and they must complete this task as fast as possible since they are preparing for war but Naruto wasn't informed of this since he's one of the main objective of the enemy in this war. The council of elders was removed by tsunade after hearing what happened from kuro who also brought the former 3rd Hokage. Hiruzen didn't even object and excused himself that he is already retired. He said that whatever tsunade wants to do is her own choice and she is now the Hokage not him. With that, the 4 teenagers were tasked by tsunade with the mission. It was kuro's first mission as a team captain. They were already near itachi's hide out which was located by Kuro's summons. They simply waited in the village and have kuro's summons search for it since they can cover a lot of ground considering they are birds. They then left a mark near the hideout which was given to them firsthand in a form of a scroll. Once kuro felt their chakra on the scroll as a signal they started gathering and teleported there. That's the convenience of having birds for a summon and Hiraishin as part of his ability.

As they were sneaking over to the hideout they were instantly greeted by Kisame who was actually waiting for them.

"You guys lost or something?" asked kisame while grinning.

"Where's itachi?!" shouted Sasuke

"He's inside and you're actually welcome to go but the three people with you aren't. I'll give them company while you chat with your dear brother." kisame answered and smiled. He was actually told by itachi to let only sasuke enter earlier.

"What? hold on. Captain don't let him go alone, that's obviously a trap!" sakura said with wariness however kuro seem to think otherwise.

"He'll be fine." was kuro's reply and looked at sasuke. "Bring him back and don't let us wait for a long time or we will force our way in." sasuke nodded after hearing kuro's decision which obviously meant that kuro trust him enough to take care of it but if he takes too long in there meant they'll assume he's in danger and they'll immediately come to help.

"What? he gets to go in all by himself? what about me?" Naruto asked as if someone who didn't get a slice of a cake.

"Huh??!!! that's not the point here!!!" sakura was getting angry since no one seems to bother about her opinion.

"See that enemy by the door?" kuro asked in annoyance while pointing at kisame who's watching them.

"Yeah? what about him?" Naruto asked in confusion.

"Since Sasuke's going in alone and probably gonna fight his brother, you should also take him on alone. Both of them are S class ninja members of the akatsuki. Let's have a race and declare whoever finishes their battle first wins, what do you think?" kuro proposed. Both agreed and are pumped up to go. But the remaining member of the team have a different opinion. Kisame also who always smiled was a little annoyed.

"Are you sure about this captain? they're the akatsuki you know?" asked sakura

"They'll be fine. Both of them were trained under a sage. So no need to worry." kuro explained while giving a thumbs up.

"That's your reason? and what are you going to do?" sakura asked but kuro was already lying on a tree branch while looking at Naruto and Kisame who were staring at each other. Sakura could only stare at him while dropping her jaw and also wondering in her head. 'what an irresponsible captain, how did you even become a jonin?? I don't get it.!'

Sasuke was able to enter the hideout no problem since kisame didn't stop him who's actually raring to go and fight naruto since he was underestimated and only has to fight one of them.

"Don't make me bored boy. Water style: Exploding Water Shock Wave" Kisame instantly change the field to his advantage as he rode the water towards naruto.

"Kage Bunshin no Jutsu.!" naruto jumped to avoid the incoming wave of water and did his signature jutsu but only 2 clones appeared. Kisame was closing in on naruto who waited for him while on a stance on top of the water field he just created.

Kisame used samehada to slash Naruto. But to his surprise Naruto closed in on him or one of his clone at least that delayed him a bit as the clone dispersed by his attack. Naruto had already formed rasengan as soon as the clone disappeared which surprised kisame by the sheer force of naruto's jutsu which also forced samehada to recoil a bit. Kisame landed a few distance away from naruto and looked at him with a smiled. "Not bad, I just might enjoy this. How about this.? Water Style: Water Shark Bullet Jutsu!" A blue shark made of water formed and lunged at naruto. His clone made an exit while he himself faced the shark bullet head on with his wind chakra all focused and gathered on his hands and feet.

"Kuro Henko Gijutsu" Naruto's chakra spiked as he readied his stance. As the shark bullet was only a few centimetres before it hits him he disappeared from his spot. 'He's fast' Kisame thought as he guarded his face with samehada.

"KazeKen!" Naruto arrived at kisame and punched him. He then made some distance afterwards as his punch did its job cutting samehada or it's cover to pieces. Samehada which was kisame's is now on full display as it's spikes moved showing that the sword was actually alive along with it's mouth taht has teeth and all. Naruto was surprised a bit but shook off the feeling immediately. "Tajuu Kage Bunshin no Jutsu!" naruto shouted as multitude clones of himself appeared. Kisame was attacked by a lot of naruto but for an S class ninja like himself this much is nothing. He simply danced in the water which was his terrain and broke every clones one by one with samehada. There was no need to transform and get serious at all.

'Smart move. This must be his new answer on how to access sage mode while in battle.' kuro thought while watching them as he clearly saw one of the clones that exited earlier gathering sage chakra.

"Water style: Exploding Water Colliding Wave!!!" Kisame rose up as water raised 3 enormous waves on top of each one with kisame on top of it all. It completely annihilated Naruto's clones which tried to overwhelm him earlier.

"Time to end this game then. Water Style: Great Shark Bullet Jutsu!!!" Kisame roared as a giant blue shark made of water appeared. Compared to his normal shark bullet earlier would be comparing a lion to a cat. However at this moment kisame felt something odd and heard a grinding sound.

He could only look in Naruto's eyes which now resembles that of a frog which has a horizontal slit and orange outline. Naruto has long since entered sage mode which was the odd feeling kisame felt. Kuro of course already knew about this as he saw the clone puffed in smoke from a distance. Alongside naruto were his clones as they are forming Rasen-shuriken.

"Sage Art Wind style: Rasen-shuriken!" naruto shouted as he raised an enormous blue chakra rotating and forming shuriken as it produced a grinding sound.

A Shark bullet vs a Rasen-shuriken

Water vs Wind/Sage

However anybody wants to describe it. It was an inevitable clash.

Kisame lauch his shark bullet as did Naruto. As the shark bullet touched Rasen-shuriken it immediately exploded and expanded. Kisame's jutsu became more bigger and stronger as if it's going to push through Rasen-shuriken. As it absorbs the chakra from Rasen-shuriken it became even more powerful and was about to go past it but suddenly became unstable due to sage chakra that was absorbed along with the wind chakra.

[AN: This is just me theorising it. I'm not really sure what would happen if they do collided but hey it's my story and I'm the boss/author LOL]

Kisame was shocked to see this and wondered why was this happening. 'Does it have something to do with the odd feeling he's giving me and that form on his eyes? He must be using another kind of chakra.'

The great shark bullet exploded and disappeared in between them. Kisame combined with samehada as he prepares for another bout with naruto. Parts of a shark grows all over his body as if a half man half shark was formed. He has a large fin on his just like a shark and a tail also. He's head figure changed to that of a sharks front head but he still maintained a hand which the fingers were now connected and his feet is still there. Exactly like a half man half shark.

[AN:If a half man half wolf is called a werewolf, then is he called a wereshark now? or sharkman? what do you think? LMAO]

Naruto's clones rushed towards kisame as he once again proceeded on a stance gathering wind sage chakra on his fist. Kisame could tell that Naruto is preparing the same jutsu he used earlier that took samehada's cover but knows it'll be a bit different considering his current sage mode form. As the two clones arrived, kisame used the terrain to his advantage as he's already fused with samehada completely. Although both the clones were in sage mode and could still react to his attacks, it didn't take him long to defeat and make them disappear. As he switched his attention to the original naruto, kisame kept his guard on. 'he's probably done preparing now, good thing i finished his clones as soon as possible which he probably sent for distraction. I don't know if a moment is all he needed but I won't back down from it' was kisame's line of thought as he also charged his jutsu not caring if Naruto will attack him now or not. He's supposed to be specialized in infiltration and information gathering but his passion has always been fighting strong opponents. Naruto's sage mode is giving him exactly that vibe.

"Water Style: Great Shark Bullet Jutsu!"

'Damn! I didn't know he still have something like that in his cards. Who would ever thought that the guy would fuse with his own sword. Furthermore the clones I sent earlier for distraction didn't even make a distraction at all.! Here I thought since they were in sage mode they could buy me enough time to be able to charge my newest jutsu.' were Naruto's thoughts as became serious at kisame who's also preparing his last jutsu, and he saw kisame enter the Great Shark Bullet. He just kept on charging his fist with sage chakra to the fullest as he can. Unlike when he enters sage mode which he balances with his own chakra inside his body, he's focusing it on one point which is his fist. Naruto was practicing this in Mt Myōboku along with Rasen-shuriken. It was afterall a Jutsu modified by kuro that's only suitable to him, and now he did the modification himself using sage chakra.

Kisame's shark bullet jutsu turned dark blue as if the great shark itself became alive, you can almost not notice that kisame is inside the jutsu. Meanwhile Naruto's hand was glowing orange color almost the same as his jinchuuriki chakra cloak. But unlike the cloak which forms like bubbles all over his body, this one looks like pure energy being emitted by his fist. The wind around him was calmly blowing as words left Naruto's mouth "Sage Art: Saidai..."

Naruto and Kisame stared at each others eyes and readied each other's Jutsu. Both Kuro and Sakura could tell it's the last exchange between them.

And just like any other face off as if on cue, a leaf flew in between them as it was carried by the wind and dropped to the ground. Kisame roared as he lunged at naruto in his fastest speed along the water terrain as Naruto disappeared from his spot as the water exploded on it.

Before both collided with their Jutsu almost near each other they shouted at the top of their lungs as it's their final exchange that will determine the battle.

Kisame: Great Feeding Shark Bullet!!!

Naruto: Sēji Kazeken!!!

And the most unexpected thing happened that kuro was so shocked he literally has his jaw dropped. Usually he's on the other side but now he's experiencing it himself. I mean who wouldn't when Naruto's hand literally cut through kisame's body with his jutsu's maximum potential unleashed. As Naruto's hand cut through kisame's body and both body parts that were severed were also cut to pieces. Kisame's shark bullet jutsu became bigger but more unstable as it exploded along with his body parts.

Kuro was dumbfounded at this and thought 'if I also successfully do that with my fire chakra and sage chakra, I wonder what the result will be'

"Finally done huh?" a voice was heard inside the hideout as sasuke and itachi came out.

"Sasuke? Have you been waiting?" asks Naruto. To which sasuke nodded.

"Damn it I lost..." says naruto weakly

"We didn't fought. technically speaking no one won yet"

"Then I'll definitely beat you when the time comes!"

Kuro and itachi talked to each other first before headed home to konoha. Strangely enough according itachi he only talked with sasuke the whole time and that he knows what's going on now and decided to go back to konoha. He also thanked kuro for taking care of danzo and agrees for him to take shisui's eyes. Now kuro has both the eyes.

Itachi was then assigned as a personal anbu bodyguard of tsunade as he cover. Tsunade also treated him from his sickness but it'll take time for him to recover. With the war about to come soon he truly needs to be in shape. Meanwhile kuro decided to train in the flying temple during the remaining time before the war. Naruto was still assigned on a mission the same as in Canon but guy wasn't one of the people that was sent with this time, he was replaced by Sasuke. Sasuke was briefed of the real mission which is to protect Naruto and keep him from knowing about the war.

Kuro went to the flying temple where time flows differently but was immediately greeted by Lord thunder.

"Kuro, come with me. It is an important matter." was the only words he said and started walking while kuro followed him with full of curiosity.

"Where are we going Lord thunder?" asked kuro in a polite manner.

"General Pyron will tell you about it. I was merely appointed to get you as soon as you return here and I've been expecting you to come"

"I understand"

Kuro then met up with General pyron who also said the same thing but this time kuro was a bit shocked for he has never met the the one who holds the highest position in the flying temple. Kuro was then lead to an underground passageway where he first met Lord thunder and General pyron. They came inside a dark room with a chamber in the middle. There lies the one who holds the highest position in this place. The room was cold and the chamber in the center was burning with dark blue flames as giant bird with dark blue feathers was lying. As Rylai open her eyes, she spoke. "You may leave General"

Pyron bowed in respect which confused kuro. As pyron left kuro's attention was back on Rylai who was looking at him.

"Welcome kuro. I am the ruler of the flying temple. My name is Rylai."

"It's a pleasure to meet you, if It doesn't offend you. May I know why you have asked for me?"

"It doesn't. And to answer your question. You have unlocked the ability to control a special element or what they call these days as kekkai genkai/kekkai tota. In your case however can't be described as a kekkai genkai or tota. Because what you have unlocked is a combination of not only three elements but four. Namely fire chakra, yin chakra, yang chakra and sage chakra. And the combination of this elements is called frostfire " As Rylai finished speaking kuro's jaw dropped. A while later he sighed a relief.

"And here I thought I wouldn't have any-" he cut off what he was about to say outloud.

"Any what?" asked rylai

"Well you know, any special powers or something." kuro almost said 'gift or system in this world'

"Well, it's the result of your hardwork. You should be proud of yourself." Kuro nodded to her and they talked more about this power and how to train it.
