Chapter 3 - Konohamaru's replacement.. Naruto's new little brother

Two days later

Luffy and his crew had just set sail, sailing away from the Conomi Islands. After defeating Arlong, the crew members and all the villagers had partied non stop. Nami had made a grand departure by stealing the wallet of everyone person that was there to see her off. She was happy for about a minute or so after she had gotten on the boat. Her happyness faded as she remembered what she saw last night when she was saying good bye to Bellemere and her old home.

Nami walked up to Luffy and strangled him "Luffy! Tell me where that ninja is!"

The reason for her anger was because when she said good bye to her old home, she found her sister Nojiko sleeping naked next to a blonde man who had immediately covered his face with his face mask as soon as Nami arrived. Nami had charged towards the bed "Get away from my sister, you pervert!" which had Naruto jump high enough out of the bed that he could stand on the ceiling, upside down, while covering his privates with his hands.

"Ohoho!" Naruto laughed "You're wrong, Navigator-chan!"

"How so!?" Nami growled.

"I'm not a pervert" Naruto said with a smirk as he held up both of his hands in front of his face, holding two thumbs up, which also meant that his privates were no longer covered "I'm a super pervert!" Naruto yelled before smashing through the roof, running away. Nami had not seen the "ninja" since then, even though she had searched for him.

"Ngggh.. I can't breeeath" Luffy whined.

"Tell me where that perverted ninja is!" Nami repeated loudly before she sighed, letting go of Luffy's neck. While Luffy was recovering, Zoro spoke his piece of mind "The baka-onna does have a point Luffy, who is that ninja and when did he become a part of our crew?"

Luffy was still breathing in hard while the other four crew members waited patiently for him to speak.

"He's a ninja, I let him join because of that!" Luffy yelled before turning to Nami "NAMI!" he yelled "That hurt!" only for Nami to strangle him again.

Meanwhile Naruto was back in Loguetown in the marine base. Before returning to visit Nojiko, he had made a large order of custom made knives. He now had more than enough tri-pronged kunai than he would ever need. (AN: a "Tri-pronged kunai" is the knife that Namikaze Minato, The Fourth Hokage, uses with the Flying Thunder God Technique). Basically, he was set to become to strongest in this world as well if he so pleased. However, Naruto wanted something else, something that involved one of the straw hats. For once, what he wanted wasn't something perverted.

A week later

Naruto had pretty much stayed inside the marine base for the full week. He had gotten a lot of things done but more importantly he had gathered a lot information and useful items. First he had applied the Thunder God seal on all of his new tri pronged kunai. He had also found out that Ace was alive and well and so was his so called father "Whitebeard". That pretty much confirmed that the war that Ace had told him about had yet to occur.

Naruto now knew where he had to go, which was the Grand Line. That's where the other important items that he had collected comes into play. He had asked Smoker to get a log pose of every Island on the grand line that was available. Since Naruto was a marine working for Garp, Smoker had given him what he had asked. At the same time he also received a tanto (AN: Basically a small, thin short sword) that was made up of "Kairoseki", sea prism stone, the stone material that has the same effect on devil fruit users as sea water, nullifying the devil fruit powers completely.

Earlier today was the only time that Naruto left the marine base during the whole week. It was when the pirate "Buggy The Clown" had attempted to execute Luffy. Naruto would have saved Luffy at the last second if wasn't for a natural occurrence saving him before he had the chance. Thunder had struck on the execution platform, saving Luffy just as Buggy's sword was about to connect with his neck. Everyone had been surprised and shocked by what they had seen, even Naruto who couldn't believe his eyes.

After that, Smoker and Tashigi had gone after the straw hats and even ended up fighting Luffy and Zoro respectively. Naruto doesn't know all the details but in the end the straw hats had ended up getting away and was now on the Merry Go once again, sailing in the sea in the middle of a storm. Smoker had ordered his marine soldiers to get a ship ready as he was going after the straw hats, he would chase them into the Grand Line if he had to. Naruto had told smoker that he was going after them first and would report back to him soon. He didn't listen to smoker as he yelled at Naruto to come back to the ship and not do anything stupid. Instead Naruto ran on top of the sea water, channeling chakra to his feet to keep himself above the water surface.

Naruto had no problem finding or catching up to the ship. He got on the Merry Go without being noticed by the others as they were busy doing something that caught Naruto's attention.

"Alright let's have a little launching ceremony to mark the importance of our voyage!" Sanji said as he lifted his right leg on top of a barrel.

"For me it's to find All Blue!"

Luffy lifted his own leg on top of it "To become the pirate king!"

Naruto's eyebrows twitched as he saw them. It was obvious what they were doing; announcing their dreams and purpose and the reason for setting out to sea. He kinda wanted to join them there, announcing his own dream, but the problem is he doesn't know what his dream is anymore. He no longer had any interest in becoming Hokage, nor would it make much sense in this world. The only thing that has been on his mind since his memory returned to him has been to find Ace and also the horrible taint that has been placed upon him after that horrible night when he mistook Kushina for Tayuya.

'To clean my dick of my mothers taint?' Naruto thought as Zoro did like Luffy and Sanji "To become the greatest swordsman!"

Nami followed soon after "To draw a map of the entire world!"

Ussop was last "To become a great warrior of the sea!" or so they thought as Naruto made his presence known, walking towards them slowly while removing his face mask. The others stared at him suspiciously while Luffy grinned. Nami blushed when she was the face of the perverted ninja but tried to hide it by glaring at him.

Naruto placed his leg on the barrel as well. The others waited for him to say something, Luffy nodded eagerly while Naruto was thinking on what to say 'Become the pussy destroyer?' Naruto thought as his eyebrows began twitching again. Then it suddenly clicked, what is that he wanted.

"To protect my crew mates as I'm trying to find a way to get back home.. debayo"

Maybe it was because of the nice moment or because that Naruto had finally shown them their face, as now all was smiling after hearing the sixth members of the straw hats announce his dream and reason to be on the ship. Everyone smiled and stared at the barrel that their feet was resting on top on, for a few seconds. Luffy then cheered loudly "Let's go to the Grand Line!"

Just as Luffy finished his sentence, Naruto had disappeared from their view once again.

"Where did he go?" Nami asked.

"Beats me, he does what he wants" Luffy said with yawn "Sanji, meat!"

"I'm up here" Naruto said as he sat on top of the mast with a sake bottle in each hand "I'll be on the look out, ttebayo"

Zoro frowned as he stared at Naruto sitting on top of the mast with no trouble at all even though they were sailing through a wild storm. 'He is strong' he thought but that wasn't the reason for Zoro's frown.

"Is that Sake?" Zoro asked.

Naruto nodded "Want some? I raided the marine base of all their sake before coming here"

Zoro grinned as he held up his hand to catch a bottle that Naruto had dropped down to him "Thanks"

The others were busy following Nami's orders as she was trying to safely get the ship to the red line.

"Zoro, pervert, you two help out as well!" Nami yelled which had Zoro sigh before pulling up his arm sleeves, waiting for instructions. Naruto however just sighed "Quiet woman" he said, which had everyone stop what they were doing to stare at Naruto in surprise or anger in Nami and Sanji's case.

"What was that!?" Nami yelled.

"Kage Bunshin No Jutsu!" (Shadow Clone Technique) Naruto said while doing a hand sign, creating ten shadow clones. The original then jumped down from the mast, landing on the deck next to Nami who was staring at the clones with a dropped jaw. Wiggling his eyebrows at her with a perverted grin he said "You may tell my clones to serve you however you want, Navigator-chan"

It got really loud after that for a moment and Naruto had to dodge Nami's punches, which he did easily by returning to the top of the mast. However there was no longer a shortage of manpower down on the deck as Nami had Naruto's clones take care of all of the work as they were entering the Grand Line through he red mountain. That was when Naruto decided that his job was done as he fell asleep sitting on top of the mast with his face mask back on. He knew that he couldn't interfere to much since that could change the events of the straw hats. His role was to watch them and protect them, kinda like a shadow. A fire shadow if you will.

Even though the crew had tried to yell at him and throw stuff at him, Naruto had not woken up until a few hours after the ship had docked in Whiskey Peak. That was a couple of days after Naruto had fallen asleep, which meant he had slept for an abnormally long amount of time.

The only reason he had woken up now was due to one of the "millions", a solder part of the secret organization Baroque Works, had climbed up the mast and tried to pull Naruto off of it. Naruto had simply punched him away then jumped down on land, heading into the Island to search for his crew mates. That million or bounty hunter, didn't realize just what kind of monster he had woken up.

A little bit grumpy about being woken up like that, Naruto headed straight into the town. Soon he saw Roronoa Zoro fighting against a whole bunch of the bounty hunters. Roronoa Zoro was someone Naruto had taken a liking to. He wanted a little brother just like Ace had, and since Konohamaru wasn't in this world, he would have to find a new one. That's right, he wanted Zoro as his little brother.

Zoro saw Naruto stand on the road below him as he himself was standing on the roof of a building, fighting several of the millions.

"Oi! You, ninja whatever your name is, your help is not needed, I can handle this!" Zoro said with a grin.

"The name is Uzumaki Naruto" Naruto said as he removed his face mask "And don't use that tone with me, Zoro-chan"

"Zoro-chan?" Zoro asked darkly.

Naruto grinned from ear to ear "That's right, I have decided that you will be my new little brother!"

Zoro sent two millions flying, then stared at Naruto with an angry expression "Don't go deciding that yourself, you weirdo!"

"Maa maa.. As your big brother I'll be teaching you a lot, such as how to become the strongest man in the world" Naruto said ending his speech with a tired sigh.

"The strongest?" Zoro asked, slightly interested.

Naruto nodded "And in return, the only thing I want is that you teach me the basic of swordsmanship"

"Tch, You're crazy!" Zoro said, deciding to ignore Naruto's offer in favor of taking care of the rest of the baroque work millions. That's when four of Baroque Work's officer agents or "Numbered" agents decided to join the fight. Along with them was a billion soldier, someone that was slightly stronger than a million. This billion soldier however, was a lot stronger than most of the numbered agents. He just never wanted that title as the only reason he joined Baroque Works in the first place was because it could help him with the bounty hunter work.

That person was Kidomaru, a ninja who was part of Orochimaru's sound four and has been defeated by Naruto or his allies twice. He also remembers both of the times very well, especially the last time when he peed himself after Naruto had Kurama stare into his soul. The numbered agents: Mr 9, Miss Wednesday, Mr 8 and Miss Monday along with Kidomaru all targeted Zoro at the same time.

Naruto's eyebrows started twitching as he saw Kidomaru "YOU AGAIN!?" he yelled.

Kidomaru turned to where the loud scream came from and just as he had suspected he knew the person who that voice belonged to. He started to back off slowly with wide eyes "No please, please not again, not you!"

With an evil grin Naruto charged up a rasengan "Zoro let me show you what I can teach you if you become my little brother"

"Huh?" Zoro said as he stared down at Naruto while at the same time strangling Miss Monday by holding her up with one hand. She had challenged him to a battle in strength and lost completely.

Naruto who still had a rasengan charged up in his right hand used his left hand to throw a Hiraishin kunai towards Kidomaru. He then used that same left hand to do a single hand sign "Ninpo: Hiraishin no Jutsu" (Ninja Arts: Flying Thunder God Technique) he appeared in front of Kidomaru faster than anyone could comprehend. Poor Kidomaru tried to send out spider webs from all over his body to defend him self but to no avail. "Rasengan!" Naruto screamed as he slammed the spiraling sphere into the torso of the former sound ninja.

Zoro was staring at Naruto with a dropped jaw while at the same time jumping to avoid Mr 8, Igaram's, trumpet shotgun bullets.

'I didn't see him move, he defeated him in less than a second' Zoro thought with a grin 'Also did he say Ninja arts? That's.. So... COOL'

Naruto yawned as he threw Kidomaru out of the road to let him rest in some nearby alley before turning to face Zoro "I can also teach you a little about haki, Ace taught me quite a bit in exchange of me teaching him ninjutsu"

"Haki?" Zoro asked.

"Yeah yeah" Naruto said in a bored tone waving him off "We'll talk about it more later, I'm tired" Naruto then walked back towards the ship while hearing Zoro's yell of "Tired? You just woke up, you lazy damn ninja!"

"I'm a motherfucking genius" Naruto mumbled to himself as he climbed up the mast to take a nap at his favorite spot.

AN: As you may have noticed, I am skipping a lot of important parts. Basically you must have read the one piece manga or watched the anime for this story to make any sense. I don't think anyone would enjoy it if I wrote out everything that happens in the manga as it would just be a copy paste. The focus is on Naruto and what he does while in the One Piece world. The rest will pretty much be the same with a few differences due to Naruto's presence.

Also more and more Naruto characters will appear in this world, some friendly and some former enemies. If you have a suggestion for a Naruto character that you would like to see in the story and what role he/she should have, then leave a review or PM me and I'll consider it. Thanks for reading!
