Right after the eventful meeting, worldwide movement began in preparation for a historical migration to another world all together. All the remaining shinobi of great five upped their training due to a warning from Naruto.
He had visited the new world few more times in random places to get better understanding and use his sage mode to get a better feeling. That was when he felt quite a bit strong presence in the new world, mostly were animals that lived in the ocean, some being much, much bigger than Tailed Beasts but also some were people with weird feeling to them.
Naruto knew that their arrival to the new world will spark conflicts right off the bat.
Now they were in Konoha once more, in the newly built village center with grand opening for teleportation and gatherings. Blonde sage stood on top of a building watching the people flock to the main road, expedition team at the middle waiting for him and Jiraiya.
"Ah, there you are brat." Mentioning the devil, old sage appeared beside the blonde, looking at the crowd. "Quite a sight, isn't it? I have only saw something like this at the start of Fourth War, but with the civilians… are you ready for a new adventure Naruto?"
"You know me Ero-sennin, I would never back down from a challenge." Naruto smirked but then frowned. "But this is not just about me anymore, we need to be careful in the new world Jiraiya-sensei. One wrong move can be our doom for real this time."
Old sage didn't reply, just looked at this student with fondness. He could see the late Hokage's visages behind the young man, hands on his shoulder, passing their will of fire.
'You would be proud of your boy, Minato… just as Hiruzen-sensei told us, he is destined to be great.'
"Well, let's not be late, I even saw Kakashi-sensei arrive early." Naruto chuckled and jumped down to the village center, followed by Jiraiya.
Expedition gathered whole in just few minutes, all of them wear newly recognized uniform of Shinobi alliance except the team leaders. Dark grey vest with no pouches but bigger shoulder pads than old flack-jackets. Dark blue or black long-sleeved shinobi shirt with matching pants and black sandals. They all had headbands with the Kanji for 'shinobi' written on it, along with bicep armbands with their original Village symbols to pay homage to their home. (1)
It is decided that Senju Tsunade, Terumi Mei, Gaara and Naruto would be the co-leaders of different squads in the team, Tsunade with her political experience and medical expertise while Mei with her expertise and knowledge about Water techniques and naval life back in Kirigakure. Gaara and Naruto chosen to be their primary assault team leaders due their overwhelming strength.
Kirigakure send their top 10 best Jounin to protect their leader along with Chojuro as personal bodyguard. Mei left Ao behind as temporary leader of Kirigakure while they are training.
Konoha sending Team 10 with Shikamaru as unit captain with Ino as a sensor along with Choji for fighting purposes. Hyuuga Hinata and Hyuuga Neji for recon due to their Byakugan and Anbu team Ro for protection of Tsunade.
Tsunade left her apprentices behind as the head of medical duties. Sakura first argued that she will also come with them but Tsunade denied her request, if something happen to them then they would lose two greatest medics they have.
Sunagakure has Gaara at the helm along with his elder sister Temari while leaving Kankuro back in Suna. They are also bringing 10 jounin with them.
Naruto due to his strength is counted as a standalone faction in the Elemental Nations and he is bringing Jiraiya, Sai and Konan as his teammates. Jiraiya's decades of information gathering and espionage isn't something that could be count out, along with Sai as his apprentice for spy network while Konan insisted that she will follow the light of their world till the end. This caused small population of Amegakure temporarily migrate to Konoha for further notice.
Team of 34 strong, ready to tackle their most important mission to date yet.
Kakashi stood in front of the team along with Raikage, Tsuchikage and Mifune flanking him. Crowd parted to either side to listen.
Grey haired Kage stepped forward to address everyone. "Today will mark a new age, new beginnings for us, for the Elemental Nations. We have suffered, countless lives were lost; fathers, mothers, daughters, sons…" People lowered their head in respect the dead. "But we have prevailed on and on, never yielding to the dark, fighting together just preserve light of hope in our hearts."
Konan looked at the back of Naruto at the mention of light. Small smile on her usual stoic face. Jiraiya and Tsunade stood side by side, smirking, they too watched their favorite blonde, second favorite in Jiraiya's opinion.
"As of now, greatest calamity in our history is upon us. We have just a year left in our beloved home, but once again, we will not lose hope, strive forward and find new place to call home for ourselves, bigger and better, living in harmony for the first time in history."
Kakashi then looked at the expedition team. "These brave people in front of us, they have been chosen for a grand purpose. Find that home." Grandiose cheer broke out in honor to expedition team. "They will venture out to the unknown, possibly fight greater enemies than we faced before but I believe that they will succeed, they will be our light in these darker times."
Sixth Hokage stepped aside, leaving the stage to the team. Naruto at the lead, all of them walked forward under the still continuing cheer.
Naruto smirked at Kakashi. "Didn't know you were such a public speaker, Kakashi-sensei."
Kakashi eye-smiled at his student, ruffling the blonde hair. "I have picked something here and there."
Naruto shook his head with a smile. Then with a deep breath he opened his left eye to activate the Rinnegan. His eyes wandered around the team that has been following him, feeling himself getting stronger just by looking at their determined faces.
"I will protect everyone… believe it." He whispered softly. Charging his chakra to a limit that he never done before.
Kurama inside the seal noticed the starting signal and gathered as much as Chakra he could while other eight Tailed beasts also started to send their chakra through their mental link to Naruto.
Naruto burst into golden chakra, overwhelming power swept through out the village, possibly other countries too.
"You are ready brat." Kurama spoke from his mind.
With a determined nod, Naruto activated the jutsu of his Rinnegan. Large purple portal opened in front of him.
"Move out!" He claimed as he watched others quickly rushing to the gate, Naruto being the last one.
Crowd that was left behind stood their places even when the portal closed down.
"Now it is up to them." Raikage said.
"Yes…" Mifune said. "But we also have our duties too."
Kurotsuchi crossed her arms. "My shinobi started on their second phase of training. Our earth techniques will be less effective in a world with such large body of ocean but our defensive jutsu still will be top notch."
"We will hold bi-weekly meetings, exchange Shinobi between villages to expand their jutsu repertoire. Have civilians quicken their packing up, also make rations and stock everything we can. Fuinjutsu specialists will be focusing on mass producing largest storage scrolls they can do." Others nodded at Kakashi's words, everyone returning to their duties.
While people on Elemental Nations returned to their posts, same purple portal opened in an entirely new place, dropping the Expedition Team.
Jounins and Anbu quickly dispersed around to create a safe zone while others landed in the center. Naruto being the last, collapsing to his knees, gasping for air. Tsunade immediately came to his side with her hand glowing green.
"How is he, princess?" Jiraiya asked, his eyes wandering around. It was a sunny day, noon by the looks of the position of the sun. one side is a small forest with palm trees while other side to them has large and open rice fields. He can smell the salty air and faintly hear waves crushing to the beach.
"He is okay. Just chakra exhaustion. He never has those so his body reacts strongly to it."
"Yeah, I'm fine." Naruto said with a cough, slowly stood to his feet, Kurama already filling his reserves with nature energy.
"You have chosen a good place brat." Jiraiya said. "We have rice fields, meaning that we are not far from a settlement. By the size of the fields… I say small to medium size village? Ino, search the island." He ordered.
Yamanaka Ino nodded, doing a half ram hand seal, she focused deeply. Her senses covered the whole island.
"You are right Jiraiya-sama. We are few minutes running away from a small village, just over a hundred population… there is also other villages on the island but we are closest to the biggest one. I also sense a small settlement just an hour away from here with just over a dozen inside. But there is something wrong with the people…"
"What is it?" Tsunade asked.
"Their chakra… they have civilian amount average but almost all of it Yang Chakra… some of them have miniscule amount of Yin Chakra… I have never sensed something like this."
"That is to be expected, we are in a different dimension after all." Jiraiya nodded. "We can conduct more research about this later on but first we need to secure a base. Yamato, create temporary house for us. It is time to get on with the plan."
An Anbu with tiger mask appeared before them, already going through hand seals.
"Wood Release: Four-Pillar House!" Slapping his palms to the ground, tree roots burst from the ground, mending with each other to create medium sized house with two-story. Team moved inside, with Jounins still maintaining the safety zone around.
"Neji, Hinata, use your byakugan to look around." Tsunade ordered immediately as the two Hyuuga nodded with veins bulging around their eyes.
Neji started to look at the people on the island, trying to find more about the people of this world while Hinata tried to see the borders of the island.
"We are at the south of the island… 350 meters from the shore while I can't see the northern border while east and west borders are barely in my Byakugan range. I count two more village but one of them doesn't have anyone inside… houses are looking quite damaged as if a typhoon passed by. I also see two settlements; one is very close with a tower in the middle of it… other is quite further away with over a hundred people inside… they seem to wear same clothes… a uniform. Two of them are quite close to the sea, having ports." It was Hinata that spoke first.
She has the farthest range on Byakugan in Hyuuga clan, being just over 20 kilometers, while Neji could see better in detail while having shorter range than most.
"Good, we have good amount land around for the first part of migration. We should also see the abandoned village; we could use it for housing for civilians in the second portion." Tsunade nodded. "Mei, please send Chojuro and 2 of your Jounin to scout the first settlement Hinata mentioned, Team Ro will scout the second one, it should be some sort of military base or something equivalent to it."
Mei nodded, already sending her men away.
"Neji report."
"People here has very underdeveloped Chakra Pathways… almost dull grey in color from negligence." Older Hyuuga said. "Almost reminds me Rock Lee's condition but his chakra is vibrant blue color. But…"
Tsunade raised an eyebrow, seeing the usual aloof Hyuuga frown in confusion. "What is it?"
"People in the first settlement… they are not humans… they look very alike to… Hoshigaki Kisame?" that surprised people, especially Mei.
"What do you mean they look alike?"
"It's just they do… they are like very large bipedal fishes… moving and acting just as humans… but only they are, others are normal humans, even if some has weird body proportions."
"We are truly in another world…" Tsunade muttered, shaking her head she talked. "We will deal with that once time comes, first we need to asses our stance on the island, to see if these people would be problem to our plans. We also need someone local to be our guide… can't just make our assumptions right of the bat."
"There is a lone person living in a small house with an orange grove behind it… she is quite close to us too." Neji said.
"Good, but we will make list for future candidates, Neji, Hinata and Ino, you guys focus on people, sense and search every detail about them." Trio nodded. "Shikamaru, you will be delivered reports from others, make plans." Lazy jounin groaned while puffing smoke but nodded nonetheless.
"Others, transform to ordinary people or hide under genjutsu, gather information. Jiraiya, along with Sai and Konan, you will sail away from the island. Go to islands closest to us, see if the islands have connection to each other or independent." Tsunade barked out orders. "We will hide ourselves for at least two weeks for further advancement. Naruto…"
Blonde sage looked at his leader. "Yes Baa-chan?"
"I know you will not like it but… I want you to be our hidden card. Hide your strength as much as possible without endangering anyone in the team. You said you felt pretty strong presences in this world, you will be our biggest force against those so hide it until the time is necessary."
Naruto narrowed his eyes but relented with a sigh. He could see the merit in it, he was powerful, very much so. If the things he felt for a brief amount of time are legit than they will need his strength. "Okay… but if anyone threatens my loved ones… no mercy." His ocean blue eyes became colder with steely look.
Tsunade smirked. "I wouldn't expect anything less, brat." With a clap of her hands, she ended the meeting. "Everyone to their duties!"
With swirl of leaves or just smoke, the room cleared quickly, leaving only Tsunade, Mei and Naruto in it. Blonde sage sighed once more.
While the new shinobi forces were making their strives in the new world, ripples of their arrival felt all over the world.
In the harsh waves of undisclosed island, a large ship that looks like a whale anchored, crew of the ship partying away with no care of the world while a giant of a man sat on a chair on the deck, IV bags connected to his arms while chug down a large bottle of sake. For a split of second his smile cracked, looking around for a bit.
"What is it pops?" a man with wild blonde hair asked to the man, holding his own mug.
"Nothing… I thought I felt something… or someone… probably nothing, return to the party." Giant answered quickly.
"Whatever you say." Blonde said, walking away, missing the frown of the giant man.
'Whoever that is… I feel things will be more interesting from now on.' His chest rumbled with laughter.
On another island, different ship with a crew were partying away like usual. Their captain being the center piece of their amusement as he danced goofy. Suddenly, captain stopped dancing, his red hair shadowing his eyes with serious expression.
"Beckman… you felt it?" he asked to his first-mate.
"Briefly." Gray haired man answered his captain. His hand on his flintlock pistol's handle. "Something strong appeared."
Captain nodded. "This will change things… I don't like it." He muttered.
In a dark large room with swords stabbed to the ground in front of a staircase that leads to a throne, a shadowy silhouette sat on it. Slowly person opened its eyes to reveal blood red eyes that is frowning.
"He came once more…" he muttered. "Not alone this time… a new faction of mystery…" It closed its eyes once more.

A/N;
1 – Same outfit as Kakashi wore in movie 'The Last'.
2- I will try to give every character their own screen time, no matter how small I will try to implement them someway.
3- First few chapters will be mostly on building the setting. Later chapters will have more action.
