Two months has passed since Shinobi expedition team took over Arlong Park, renovating to their use. Shark heads were immediately taken down and replaced with flag poles with white flag that has kanji for 'Shinobi' on it. Something they decided to be known in this world so that people will know who to call on.
Yellow walls painted white with red tiles of the roofs became grey. The pool became larger to accommodate two ships to port at the same time with base walls pushed away more outside for new structures such as warehouse and living quarters. Yamato was worked quite hard to create houses around the base and ships to sail around, something that depressed the Anbu commander quite a bit.
You could hear him sleep talking, begging Tsunade to stop using him as a carpenter, it was a long two months for the Mokuton user.
On the fifth day of Arlong's death, a Marine ship showed up at the island, scaring the locals as they believed Marines were here to arrest their saviors but turns out Arlong crew attacked 16th Marine Branch, killing almost all of them with Nezumi and his officers being in the causalities. Arlong seemingly were killed by the Shinobi Mercenaries and Marines were here to give their bounty rewards and clean the Marine Branch. Anbu team already made copies of each document just in case.
Nami and Nojiko then understood the strength of the new group, being able to transform as others and push the suspicion to others as easy as breathing.
As per their request, Naruto started to train the sisters on the usage of Chakra. They mostly did meditation and leaf sticking exercise, it's a very slow progress but in couple months they will be able to do bare minimum with their Chakra.
Outside of their training, Nami and Nojiko also were assigned to their new duties in the faction. Nami continued to be the cartographer, Tsunade created a new division of cartographers as Nami at the lead. She will teach other Shinobi in the art of map making while also giving Navigation lessons about the treacherous and unpredictable seas of the new world Shinobi found themselves in.
Nojiko is assigned to Tsunade as her newest secretary. Just like the blue haired girl said, she is quite diligent and has talent in paperwork, lifting much needed stress from Tsunade's shoulders so she can day drink without Shizune to scold her here.
Conomi Island citizens also helped their saviors. Yamato worked with a retired boat maker in the island to make their ships as he can only make the wood parts but boat maker and his workers can make the riggings along with the sails.
It is a medium sized, three masted ships that they decided on, called Fluyt type. Has three decks and a captain quarters. First is the open deck above, unlike other ships Shinobi ships don't have any cannons on board. It is unnecessary weight when you can breathe fireballs size of a house to your enemies.
Second deck, just belove the surface is the living quarters for the crew complete with bunk beds, living space and kitchen. Lowest deck is for cargo and also space for a brig to hold prisoners inside. Captains quarter is for the leader of the shinobi crew manning the ship, equip with a bed, table with maps and Den-Den Mushi snail so that civilians can contact them. They also have radios that they brought from Elemental Nations, with the existence of Black Den-Den Mushi means someone can tap into their secrets.
Every ship has a small satellite built into them to cover larger area of communications.
Hull of the ships are painted dark grey with white sails and a flag. They all had their faction Kanji 'Shinobi' on it to identify themselves. Being made from Mokuton ability, all the ships were quite tough but in turn became heavy and slow. Problem that can be solved easily with Wind and Water Jutsu users.
With the help of citizens and hard work of Yamato, they have created 25 ship ready to sail. Quite a feat but Yamato's hobby of reading architecture books and boat maker's experience helped them quite a bit.
Now the Shinobi were gathered outside their base, along with Nami, Nojiko and locals.
"I am still unable to comprehend that you guys are from another world altogether." Nojiko said. "I heard about devil fruits and their mythical powers but this seems much more fairy tale like than those."
"And to us these Devil Fruits are fairy tale like." Jiraiya spoke.
Shinobis were quite intrigued with the existence of so-called Devil Fruits. Until Jiraiya actually met a pirate in person that has eaten the fruit in his espionage.
Pirate crew that has took over the Clockwork Island, Shinobis next target for building a Headquarters. Their captain, Bear King, seemed to eat a fruit that allowed him to strength his body by covering himself with rocks. He could also heat up his body to cause more damage.
Their second-in command also has a devil fruit that allows her to change her body to some type of liquid, nullifying any damage done to her body and also use the same liquid to attack her enemies.
But nothing that Jiraiya the Gallant, pleasurer of Woman, scorn of Men, the great toad sage can't handle. He took care of the pirate crew in couple minutes tops.
It posed a problem for the newly founded faction but the biggest weakness of the Devil Fruits was a welcomed news, sea water or any body of water with enough depth that will nullify their strength, leaving them in danger. It is their biggest advantage against the devil fruits, as almost all of them can use Water based Jutsu and can be undefeated in Naval battles as they can just stand on top of it, sinking other ships easily.
But this also made them especially dangerous in the eyes of others, World Government and strong pirates surely be gunning for them.
"So… how many of you people are there actually?" Nami asked, eager to meet others. But she is especially waits for Naruto, he has been away over a week. "Largest Crew there is I know about belongs to Whitebeard. He has the largest allied crew under him and I heard his own crew is almost like military with divisions. It is believed that he has over 5 thousand pirates under his flag."
Before joining the Shinobis, Nami didn't bothered with reading much about the other seas, she just focused on East Blue but under the tutelage of Shinobi, she gradually learned the power of knowledge and focused on reading anything she could about other seas, especially the Grand Line and the pirate crews there is.
Her hatred for Pirates didn't diminish in the slightest.
Jiraiya smirked knowingly, making Nami blush. "Wait and see for yourself…" they continued to wait.
On the other side of the dimension, Elemental Nations were on the move once again, preparing for another parting. Naruto stood at the teleporting center of Konoha, talking with Kakashi and other Kages.
"So, pirates…" Raikage hummed. "It was a good decision on that lazy Jounin to be mercenaries. Our military is already suited for that purpose, we can even use low risk missions to train the next generation once again to bring our numbers where it used to be."
Others nodded at his input. All villages hit their all-time low on military numbers. They had 80 thousand Shinobi and samurai combined in the start of Fourth Great War but they lost over half of it in the first day of fighting. Fifth war also did quite a big damage to it, bringing their numbers to only over 15 thousand, close to 3 thousand per village.
Far cry from the average well over 10 thousand they used to have.
"We will think about future generations after we fully settled and declared our land." Mifune said. "But I also think Nara-san made a good plan. My samurai forces can be used as security details to islands that don't have much money or excluded by World Government as insignificant. It will be our honor to protect the innocent."
"That is great." Kakashi smiled. "Shinobi will be our main fighting force against our enemies and will hunt down pirates… but I am still worried about World Government. They could declare us criminals and ruin our income."
"True, but Baa-chan and Shikamaru is working on something about it… it includes Marines but I don't know the details." Naruto said. "I think we are all ready?"
He gestured the gathered Shinobi in front of them. This time it will be the entirety of Kirigakure, Kumogakure and Sunagakure military force with half of the Samurai will follow Naruto to other side. Kirigakure is irreplaceable with their Water jutsu and Sunagakure with Kumogakure Shinobi can also aid their voyage in the seas quite a bit. Samurai's will be their ground force in Conomi island for the time being.
Every Shinobi and Samurai has sealing scrolls size of their body attached to their back, containing personal items along with large amount of arsenal.
On the side Naruto also saw Isobu, Three Tailed Beast, waiting with Killer Bee. They are their main force in the seas, almost unbeatable inside water.
Tailed beasts at first wanted to stay alone in the Elemental Nations but feared that Otsutsuki might return just like Kaguya and decided to follow Naruto.
"Yes, we are." Kakashi signaled his man to power up the chakra batteries. "Almost 9 thousand personnel… will you be alright Naruto?"
"Dattebayo!" It was the answer as Naruto tapped in to his own power. A cord of some sorts attached to his stomach to supply chakra to him.
Once again under the cheers of civilians, large portal opened to other world, allowing Shinobi to rush through. Naruto felt increasingly exhausted with each passing Shinobi but held strong until everyone entered with Kages and Naruto being the last.
Only Kakashi, Mifune and Kurotsuchi left behind.
"Tch… why do I have to wait until last?" Female Kage grumbled making the older man chuckle. They could see that she wanted to explore the new world too but stuck with security purpose in the old world.
"… Then Hinata helped us focusing better on our chakra to stick the leaf. We were able to stick it for ten minutes straight, even walked around." Nojiko talked with Tsunade excitedly. "Naruto is a great person but his… explanations always have to do with Ramen for some reason…"
People around chuckled at her conundrum.
"Aww… you hurt me Nojiko-chan." Warm breath tickled her ear as she jumped away shrieking, making Naruto double in pain from laughter, his body aching with pain.
"Hahahahaha! That was great!" He laughed, his mismatched eyes lighting up with mischief.
"You!" Nojiko yelled, wanting to hit the blonde sage but her breath caught in her throat, seeing the sheer amount of people behind Naruto.
"Holy shit…" Nami cursed, trying to count but giving up after first hundred. And there is also a giant turtle beast at the end. She could feel the sheer power on her skin even though it just looks around calmly.
"You think Whitebread crew size will be problem?" Jiraiya smirked once again.
"And this is only half of it?"
"Around that much." Naruto said, still panting heavily from exhaustion. "Teleporting Tailed Beasts takes more chakra than I have thought… I need to be divided the last teleportation to parts I believe."
"That will be for the best… now let's have our people settle in. our job only starts now."
They moved the newly arrived forces to the living area Yamato created for them, a small size village, but actually the biggest in the island, it is a neatly arranged houses with three story and apartment style. Each flat can house 10 Shinobi at the same time while the married shinobi can have their own private flats.
This also encourages comradery between the Shinobi from different villages.
While they were settling in, Kage and team leaders have their own meeting in the headquarters. Tsunade sat at the head of the table while backed by Nojiko, Kages flanking her with their own assistants. Jiraiya has Sai behind him, Naruto with Konan, Raikage with his faithful secretary Mabui, Mei with Ao, Gaara and Temari, a single Samurai covered with blood red armor and lastly but not least Nami.
They have once again gone over the events happened before the force's arrival and plans they have created along with the progress on it.
Mabui looked at her spreadsheet, notes of the meeting in neat handwriting.
"We should create decent size crew as it is the structure of this world. Ships that Yamato-san build are big enough to house 30- or 40-person crew easily."
"Yes." Mei nodded. "My men will be the ones that manning the ships, skeleton crew as you can say it. Our jutsu will make them nightmare in Naval battles and we already have training in sailing due to Kiri being combination of islands. Shinobi from Sunagakure also should be added to it as their Wind jutsu will make it easier to sail and even redirect storms that can be harmful."
"Then Kumo and Samurai forces will be the ground teams until we have our full force. My men are suitable for covert operations while Samurai can be the public face of us." Raikage crossed his arms.
"We have already created prototype crews, Shikamaru theorized the arriving forces and made plans for it." Tsunade said, giving them documents. "We already had Jiraiya and Sai giving out our Den-Den Mushi numbers along with custom made flyers with the introduction to the public these past months. even locals of Conomi island contacted some of their friends in other islands, giving our advertisement."
Jiraiya spoke next. "We will use the same mission ranking system we had here too but with extensive background check with mission itself and the client. One wrong move or misjudged assassination can put our whole organization in jeopardy with bounties on our heads. We can fight the Marines easy enough with our full force, but there is no need for unnecessary bloodshed."
"True…" Naruto nodded. While he despised World Government after learning how they truly operate, something that ordinary citizen can't see unless they see it with their own eyes. But Marines on the other hand… they were just people that wanted to do good and protect the innocent, only to be corrupted or used by those in high places.
"We already have Jiraiya and Sai handling the Marines." Tsunade said. "We already have the entire patrolling routes and schedule they have in East Blue. Jiraiya will choose personnel for his new Espionage and Intelligence unit amongst our newly arrived force, he and Sai will train them and sail the seas, gathering information and resources for our use. We will also infiltrate other organizations, there is high chance some will turn on us, we can destabilize them from within if that happens."
It is the most basic planning of a Shinobi of their world. Appearantly people of this world lacked the skill in stealth or sensing others from what they gathered, making their job that much easier. Also, they were pretty loose lipped after getting hit couple of times.
"Good…" Raikage nodded, then his eyes locked on Nami, she shrieked back little seeing the large man glaring at her. "Pray tell why we have locals in the meeting?"
Naruto chuckled. "She is Nami, and her sister Nojiko there. She is wicked good with maps and navigation so we made her the head of cartography unit. She is still in training and only person in her unit but I believe she will be invaluable for us. Nojiko is also very smart, and I know Baa-chan dumped all of the paperwork on her already."
Nami blushed from being praised while Nojiko sulked at the corner. She cursed the day that she accepted paperwork. Tsunade only smirked, sipping from a sake bottle that she sneaked inside to meeting room.
"They will be your responsibility then… I don't want foreigners destroying our structure." Raikage grumbled, getting other roll their eyes at him.
Meeting continued for a while, creating ship crews and preparations for rebuilding the Clockwork Island for their use. Trump Pirates under Bear King destroyed much of it and caused the civilians to abandon their homes. But that could wait for a while as they needed big capital for future.
