A/N Here is another part of Uchiha Siblings, no rants in plan for today. Reviews as usual below it. This chapter is a little brutal and full of gore, but assassinations are like this and here they have hundreds of targets that need to be killed.

Once orders were issued whole group split into smaller teams in which they were going to work for the time being. Naruto, Sasuke, Kakashi and Asuma were going to have the most dangerous job out of all of them as they were going to poke around hornets nest and they were going to shake it a little. Naruto looked at lazy jonin that was his partner for this mission and jumped onto the branch of tree nearby, where he was followed by him.

"Naruto what do you know about infiltration and data gathering?" Asked Asuma as he landed on that branch near Naruto.

"A lot." Replied Naruto "I did some of such things with aniki or Shisui-nii when we were training away from the village."

"Good" Said Asuma looking at Naruto "It will be less troublesome since you know how to do that. Do not show yourself to enemy and when I say that you need to do something you do that."

"Hai, hai" Said Naruto as he scratched back of his head, partially annoyed and partially in shame as he was known for being a hothead.

"Good." Said Asuma "Let's go."

Naruto looked at Asuma and nodded, both of them started jumping towards middle of the island looking for any data about enemy and counting thugs they were able to find as they did so. They were running through the forests and were avoiding as many enemies as they could. So that nobody could tell the main force what was going on. After over five minutes of running they found themselves perched on a large branch above clearing where they saw multiple quickly constructed shelters, tents and primitive houses placed there without any pattern or idea about what was done there. One was standing in one place, second thirty meters to its left, third five to the right and so on.

"Nice chaos." Said Naruto as he saw that camp. It would make a nice bonfire with a little help of Katon jutsu.

"Yes." Agreed Asuma "They feel safe, so they don't care about security of their camp and placing any sentries to alarm if enemy is close. We could propably enter it and we wouldn't be noticed by them, they would assume we are just another two nukenin in service of Gato. Where are your clones?"

"They got here something like ten minutes ago or so." Said Naruto as he focused for a moment "They are looking around it and are taking a count of those thugs."

Sasuke and Kakashi were running through the forests and were looking for second base of Gato, one that would house his nukenin and propably his personal bodyguards. They had an idea or two were to look, but doing that was actually complete different than knowing where to look.

"It looks like we have luck." Said Sasuke "I can pick up a lot of chakra sources coming from one place."

"Can you take us there?" Asking Kakashi "They most propably are what are we searching for."

"I think so." Said Sasuke and turned slightly to the right, as it was the direction from which those sources were coming and they ran in that direction. Jumping from a tree branch to another, not making a single noise, they stayed silent as they were running, so not to let know the enemy they were here and have another level of protection.

After five minutes or so they landed inside of small bush from which was a rather good view of clearing in front of them. There was a large, four stories tall building built out of concrete and it looked like it was the base for Gato shinobi.

"That's quite a lot of them." Said Kakashi gazing "They might be a problem."

"Also there are ones that are in the building." Added Sasuke "And ones that aren't here at the moment."

"Yes." Said his sensei nodding in agreement and understanding. He didn't say this one as he wanted to check if Sasuke would guess where some of them could also be. "But that is less important than knowing where they are and where we need to strike. If we take out most of them those that will remain will be just needed to be hunted. Naruto clones should give us most of data we will need to do this."

When first true day of their stay in Wave was getting to close, that is it was an afternoon whole group once again gathered in one spot to talk about what they had found.

"They have over eight hundred thugs and forty nukenin." Said Kakashi once he saw numbers that were estimated by Naruto clones and Shikamaru "We need to take out as many of them at night as possible."

"Assassination it is." Said Asuma and looked over genin "I, Kakashi, Naruto and Sasuke will need to do that, while rests of you guards the client."

"But why they will go with you?" Asked Ino

"Because they are ones that can actually help us." Said Kakashi and looked at them. "Get ready, I want to get there right after the dusk."

Naruto and Sasuke nodded, they walked to their room and took out two small scrolls from their backpacks. They slammed them onto the floor of it and unsealed content of them, when they did that there was a poof of smoke and in front of them were laying matte black armors and jars of paint of various dark colors. They painted every single piece of skin that could be visible in various shades of black, gray and blue thus removing any lines that could betray them.

It had double purpose, first to be used as an concealment and second as a way to scare their enemies, it was one of tricks utilized by their clan in combination with their Sharingan as it made them look like demons. Especially in bad visibility and when enemy was a little scared.

When they got out of the room they were wearing their armors over their bodies, which they were painted in various colors that made them also look scary. Naruto over his hair tied bandanna, to make them look less like an eyesore and so that they were less obvious sign of who he was. On his back were his usual swords and sabers, he was looking quite deadly.

"You look scary." Said Chouji when he saw them walking down the stairs, paint covering their bodies in weird swirls and lines that weren't painted in any patterns or set ways. He shuddered when Sasuke and Naruto eyes changed into Sharingan and they looked like two devils or demons.

"They look good." Said Kakashi "Ready to go?"

"Yes" Said Asuma as he put his trench knives into their scabbards that were on his belt. "How are we going to do that?"

"We will split." Said Kakashi "I will go with Naruto and deal with nukenin, while you and Sasuke will deal with thugs. Once you will do that, join us and help with those nukenin as they might be a problem. Rest of you protect the client, Shikamaru you are in charge."

"Hai" Said lazy Nara and watched as the team left the building.

Once they left the building, they split up into two people teams. Naruto and Kakashi ran towards concrete building, while Asuma and Sasuke towards that camp. They traveled silently not talking about what was going to happen as nobody wanted to do that as it was one of the most vile thing that ninja were asked to do.

Naruto and Kakashi landed on the branch overlooking the clearing and looked there. Naruto breathing and heart rate was slightly increased. Sign easily read by Kakashi as mix of trepidation and a bit of fear, which was usual thing before such missions as nobody liked doing them.

"Calm down." Said Kakashi, placing hand on Naruto shoulder, patting it lightly. "It's a mission, there is nothing exciting about it."

"I know." Said Naruto and sighed. "Let's get it done." He lightly jumped down onto the ground, where he was joined by his sensei, who uncovered his Sharingan which glowed menacingly, giving Kakashi scary look. One eye was normal one, while second glowed like it had belonged to a demon.

"Do not toy with your enemies." Said Kakashi "If you need to kill him, just do that. There is no point in toying and it is cruel. If you don't want to do that this is the last moment you can go back."

"I don't want to go back." Said Naruto "I will do it till the end."

"Okay." Said Kakashi and grabbed tanto strapped to his back. His movements were repeated by Naruto who grabbed one of his katana, he was going to use only one as it was mission when they would be mainly slitting throats and excluding that there would be not much else to be done. "You will take two lower floors, I will take remaining ones as they will probably have more dangerous enemies."

"Hai" Said Naruto as he walked into the building no following his sensei. When they opened doors and walked into the first room that was inside they saw only bare walls and that was it. There was nothing on them and everything was extremely basic and utilitarian in design. It looked like nobody wanted to pay for luxuries here.

Kakashi looked at Naruto pointing at the doors and passed a message that he should wait. Kakashi opened doors and looked inside, he noticed flights of stairs going upwards and doors near them. Everything was rather crude and rather used, also in the air was strong stench of bad quality sake and of unwashed bodies.

"We will split here." Said Kakashi "I will go upstairs, while you have this and next floor. Do not use flashy jutsu, be quiet and kill them quickly."

"Hai" Said Naruto and moved towards the doors, where he took a quick breath and opened them, walking forward into dimly lit corridor that was in front of them. His eyes were able to pierce the darkness of it and he was able to clearly see what was happening. Walls were bare, but we're covered in dirt and other things. Also stench of sake and of unwashed bodies was even stronger in this corridor and Naruto stomach was trying to go rebel on him as it didn't like the stink that was in this corridor.

He steeled himself and moved towards first room that was there, he opened doors inside and saw there three genin and a jonin from Ame. He silently crept forward and before first could wake up and notice what was happening he brought down his sword onto his neck, severing head from the rest of the body. Before the rest of them notice what was happening their heads were rolling away from their bodies and from severed veins was flowing out blood.

Naruto winced when he killed them, but he knew he didn't have any real choice, he knew if he didn't kill them, they would kill him. He kept him nerves under control as he was taught to do so, he sealed cut off heads into storage scrolls as to get a reward for them and moved to the next room. He did the same thing there and repeated it all over the first floor and when he got up the stairs, he was covered in blood from all of those kills as couple of them tried to struggle against him and he was forced to kill them in shower of blood and gore that got splattered all over his clothes.

He walked up the stairs and when he entered through the doors at the end of them on first floor, he was met by several nukenin in there. That looked like they were going to fight themselves when they saw Naruto.

"Looks like we need to finish our fight later." Said one of them "We will kill him first and later we will solve our issues with each other as he just interrupted our duel."

"It seems you right Menma." Said one of them, one that had sharpened canines and two swords strapped to his back.

"I am always right Raiga." Said one called Menma and looked at Naruto. He flashed through the handseals and shouted "Katon – Goryuka no Jutsu", he exhaled large dragon shaped fireball that charged at Naruto, who jumped to his right and allowed it to pass safely to his left.

"That was a tad rude." Said Naruto and started flashing through chain of handseals "Katon – Hosenka no Jutsu", when he did that he exhaled several small flower shaped fireballs that were almost white in color and charged towards his opponents. They dodged out of the way of those fireballs and looked at Naruto, who was now visible with fires dancing in his eyes, that looked like a Sharingan.

"So an Uchiha." Said Raiga "Last time I fought one when we were waging a war on Konoha."

"Nice." Said Naruto "Second member of Swordsmen to my collection. Kurosuki Raiga."

"And you are who?" Asked Kurosuki

"Uchiha Naruto, adopted son of Uchiha Fugaku." Said Naruto looking at Raiga. "Maybe you should take out your Kiba swords?"

"I don't need them against such runts as you." Said Raiga

"If think you will change your opinion about me in a moment." Said Naruto grabbing two of his sabers and taking them out of their scabbards. He held them confidently in his hands and chakra from his body entered them lighting them yellow or gold, not to mention extending blade length.

"Impossible, sabers of the Yondaime." Said Raiga looking at them. His thoughts about not using Kiba swords against this runt disappeared, he had sabers of Yondaime and that was completely different kettle of fish. "You got this kid, but don't cry when I will beat you."

"I'm planning on beating you, I don't plan to lose here." Said Naruto as his Sharingan started spinning, faster and faster. He charged at Raiga, both sabers at ready, while his mind was analyzing everything it knew about Raiga and his swords which were one of more normal looking swords of the Mist.

Raiga replied with his own charge and charged at Naruto, with whom he crashed in midair. Chakra coating their blades sizzling and fighting for dominance, trying to see who was stronger and better. After few moments of such struggle, they broke apart and jumped away from each other, looking at themselves and assessing their situation.

Next charge was made by Raiga, who charged at Naruto, who in turn fell into defensive stance of style that he used and with troubles, but successfully stopped those blades that were charging at him. After that he used his leg to kick his opponent and sent him tumbling onto the ground and tried to finish him off, but before he could. Raiga recoiled like a viper and brought his blades to parry strikes charging at him with a frightening speed and ready to cleave him in half.

They jumped away from each other, sweat slowly covering their bodies as exhaustion from a fight took its toll on their bodies. When they were going to once again renew their duel, rooms to the room opened and through them walked Asuma and Sasuke, who quickly looked around and moved into defensive positions.

"Do not interfere." Said Naruto, not looking back as his chakra sensing told him who was coming. "He is mine. I want to finish this duel on my own."

"If you insist we won't interfere." Said Asuma as he watched with worry Naruto, who looked like he entered some sort of trance and wasn't going to come out of it. "But we will deal with other ninja."

"I don't care about them." Said Naruto "I care about him."

After those words Naruto charged at Raiga, forcing him onto defensive as now he was channeling huge amounts of chakra into his limbs and thus making every strike stronger, faster and generally more powerful. For Raiga each one of them felt like a hammer was hitting him, one at the time and after five minutes of such beating he was almost on his knees, exhausted and panting. While Naruto wasn't in way better shape than him as he was panting, sweat was covering his whole body and he was exhausted from it, but it was obvious he had more chakra that Raiga. Naruto brought final strike down onto Raiga, broke through his guard and left two deep gashes across his chest.

Raiga couldn't believe what happened, he lost to mere brat. For a moment nothing happened, but then blood exploded from those two gashes and started spilling onto the floor around them. Raiga slumped forward and fall into the pool formed by his own blood, swords slipping out of his grasp. Naruto didn't fare that much better, as he also slumped forward and lost consciousness from sheer exhaustion as this fight took quite a toll on his body.

"I can't believe it." Said Asuma when he saw what happened "Genin, not even thirteen years old did something that many adult shinobi couldn't do. He beat member of the Kiri no Shinobigatana Shinchinin Shu, twice."

After that Asuma moved to the body of Naruto and checked if he could feel beating of his heart, it was there, but it was really faint and hard to detect. It seemed like a classic example of old fashioned chakra exhaustion, which weren't completely normal thing, but were a common occurrence and every shinobi suffered one at least few times in his life.

"He should be fine." Said Asuma as he picked up body of Naruto, which was covered in blood and few other things. "He is just exhausted, Sasuke take Naruto sabers, Kiba sword and head of Raiga. We will get a nice bounty for his head."

Sasuke nodded, grabbed his sword and chopped off head of Raiga from the rest of his body, sealed it into storage scroll, grabbed Naruto sabers and Kiba swords. Once it was done he once again looked over the area, looking for any troubles that could still linger there.

"What had happened to Naruto?" Asked Kakashi when he saw Asuma carrying his student slung over his shoulder and looking quite exhausted.

"Chakra exhaustion after duel with the member of the seven." Said Asuma "Twin Lightning of Kiri."

"Kurosuki Raiga." Said Kakashi and sighed "He will be in bingo books in matter of days and he will propably get kill on sight order from Kiri. Just wonderful. Let's go."

They nodded and ran after Kakashi towards place where they were staying and would be for few more days, that is until the bridge was finished and Nami was safe. When they were running it was so late or early that sun was going to soon appear over the horizon, there were maybe two or three hours left before the dawn. Once they landed in front of the building Kakashi pushed doors open and walked in, where he came face to face with pointed kunai held by usually lazy Nara.

"It is just me." Said Kakashi "We got back. Had small complications, but everything is done. Oh and Naruto exhausted his own chakra reserves, other than that it is fine."

Shikamaru nodded and let them inside, his eyes widened a little when he saw how Naruto looked with blood soaked clothes and being pale, it was visible even with paint covering most of his body. Not to mention that there were quite a few smaller or bigger cuts covering his body, from which were oozing small trickles of blood.

Sasuke didn't look that bad, but it was obvious for Shikamaru that he was exhausted and he needed to get over a lot of emotional issues as he was propably for the first time assassinating a person and so far he was running on adrenaline.

Sasuke was kneeling in front of loo, in his mouth he felt bile as his body was shaking as he was vomiting, while his mind was replaying and replaying memories of what he had done this day. He knew it was necessary, but he never thought it would be so hard on his mind later. He now was able why Naruto after that kidnapping attempt was so quiet and reserved. His mind was coping with what had happened that night, when he killed in self defense.

"This will help you." Said Kakashi handing Sasuke small cup "It is strong tea with few additions that will sooth your stomach and I added few that will knock you out for next few hours or so, so that you can rest.

"Thank you, sensei." Said Sasuke as he drunk it, it tasted terrible. After that he walked to his bed in the room which male members of team seven were sharing and went to sleep there.

"Where are Sasuke-kun and Naruto?" Asked Sakura when she noticed lack of two members of her team.

"Sleeping and getting over the events of yesterday night." Said Kakashi "Naruto exhausted his chakra, while for Sasuke it was first true assassination mission and they usually take quite a toll on both mind and body. Don't ask them about it, they propably won't be willing to talk about it for next few days, if ever."

"How long is it going to take Naruto to get over the exhaustion?" Asked Ino

"He is Uzumaki and there is his condition, while normal shinobi would need around two to three days. He should be up and running in hour or two." Said Kakashi "Assuming nothing will change we will hunt down Gato today and we can be back in Konoha in week or so, maybe faster if Naruto is going to hitch us a ride."

When Gato accompanied by two of his bodyguards entered building which was occupied by his company first thing that he saw were bodies of his thugs and of nukenin he hired, some of them missing their heads and every single useful piece of equipment. There was blood everywhere and it looked like he had guests at night, while he was in the brothel, which saved his life from being killed by those unknown people that visited this building, leaving behind only corpses and blood. He paled when he took a better look of a carnage in front of him, as it seemed that some of those people were killed in rather painful way, while some died simply ambushed in their sleep. It was a sign that whoever did this knew his job well and was ruthless killer as nobody was spared from the same treatment, while it was obvious that some plead those killers to spare them.

Naruto two hours or so after rest of the team met, woke up and looked around, he felt like hammer had hit him couple of times and he had massive headache. He groaned, getting up and saw that he was still in his armor, which meant that he lost consciousness when doing their mission and was dragged by someone back into their base and left to regenerate. He grabbed fresh clothes that weren't stinking of blood or sweat and walked with them to bathroom to get himself cleaned from all that grime, gore and dirt.

Dozens minutes later he was in fresh clothes and walked downstairs to met with the rest of the team and to get something to eat. When he walked to the room he saw rest of the team sitting there and eating their breakfast.

"Morning." Said Kakashi "Already awake? I thought you will need more time to wake up"

"It wasn't my first exhaustion." Said Naruto as he sat in one of free places at the table.

"How does it sound Konoha no Tsubasa Akuma?" Asked Asuma looking at Naruto.

"It has a nice ring to it." Said Naruto

"And it suits you." Said Kakashi "Whatever you say you are quite a deadly one with a blade. It looks like Uzumaki blood flows quite strongly in you."

"It does." Agreed Asuma "Kakashi how are you planning on dealing with Gato?"

"Since one of us is known for summoning large cats and second for dogs." Said Kakashi "I don't think it will be hard to find him and deal with him. I think that it is safe enough for you Asuma to take your team and go with Tazuna and start construction works. While I and Naruto will have a nice hunt for our target."

Naruto focused on his chakra and pulled from Kyubi pool of it, he bit his thumb, smeared blood over Tiger tattoo and slammed his palm onto the ground. There was a large poof of smoke and when it was gone they could see rather large tiger, sitting besides Naruto.

"As I was going to say." Said Asuma glaring at Seishin, who only bared his fangs at Asuma in reply. "That is a pretty good plan. I don't think we need to stay here all the time. Gato lost most of his fangs and now is rather defenseless. Faster we get it done the faster we can be back."

"Why did you summon me?" Asked Seishin looking at Naruto.

"We need to track down one person. Can you help us?" Asked Naruto looking at him.

"Hunt, than." Said Seishin "Last good one was few months ago, so with a pleasure."

"Good." Said Naruto "So Kakashi-sensei when do you want to start it?"

"Meet me in fifteen minutes outside." Said Kakashi "Bring only light gear."

Fifteen minutes later Naruto stood on the wall of Tazuna house, Seishin standing besides him and waited for Kakashi to appear. Few moments later from the house got out Kakashi in his plain gray ANBU armor and in hand he was holding small piece of cloth. Propably carrying a scent of target they needed to find.

"Come down here." Said Kakashi looking at Naruto, once Naruto jumped down, he looked at Seishin "Can you find the smell of person that left it on this piece of cloth?"

Seishin moved closer to that piece of clothing and tried to get the scent of their prey. Once he did that he raised his head into the air and looked around, after a moment he sped off in one direction, ears flat and claws visible. It shocked a little Kakashi and Naruto, but after a moment they charged after him. Naruto was used to speed those Tigers could achieve, but even he was shocked by one showed by his familiar.

"I thought that he didn't have any guards that survived the night." Said Naruto when he saw Seishin ripping throat of some thug open. To his right Kakashi pulled out kunai lodged inside of the eye of one of other thugs.

"Not only you." Said Kakashi, they easily found Gato or at least the building where he should be, but getting inside wasn't so easy as there was guard on top of another and getting through them was a little annoying. So far there were fifteen corpses left by them behind, some of them looked like they met angry chainsaw as throats were ripped open and there were bite marks of rather big and nasty cat, with claws big enough to do that.

"I hope this was the last one." Said Naruto as he stabbed one of them and killed him on the spot. After that he glanced at Seishin and saw that his muzzle was covered in blood, both fresh and dried one. He looked rather scary with blood all around his mouth and paws.

"It looks like it is." Said Kakashi as he pushed doors open and walked into rather large room. It was richly furnished and inside they found one man, that was their target. Gato, who was an owner of Gato Shipping and disgustingly rich man, not to mention that he was a midget. "Who do we have here?" Asked Kakashi walking forward towards Gato.

"Looks like we have luck." Said Naruto as he also walked forward "Gato of the Gato Shipping Company I presume."

"Yes" Said Gato and paled when he saw looks on shinobi faces, even if he couldn't read those looks. Snarling Seishin would give him more than enough of reasons to fear.

"He is all yours." Said Naruto looking at Seishin who nodded and lunged at Gato, blood curling roar following him in his path. Gato was thrown onto his back by Seishin, who landed with soft thud onto Gato chest and moments later screams of panic from Gato ended with sickening crunch when powerful jaws of white tiger closed over his neck and snapped his spine.

"That was a good little hunt." Said Seishin, licking blood from his mouth. "I need to return to my home to rest, but I will answer your summon."

"Thank you Seishin." Said Naruto and watched as his summon disappeared in poof of smoke.

A/N – Reviews

"I think that's Itachi and Shisui should be contacted as well It's going to helpful as well. Naruto should unlock more about his own eyes and fine more stuff about the Uzumaki stuff in Gato's hideout after all." – Too big of an overkill, what's the point of bringing half of ANBU squad when two jonin and their genin teams can handle the problem? Remember that ANBU are in limited supply and every single one of them is precious. You don't call for special forces when normal ones can handle the issue without troubles. About his eyes, who said that he didn't unlock it? It isn't shown here, because there is no need for him to use it and about Uzumaki clan, there will be something related to it, but later.
