The war in the underworld was not going like how everyone expected some thought it was just going to be a glorified sparring match between factions others thought that they would finally rise through the ranks and the last thought that they could finally prove themselves to their families as well as to their masters or superiors however no one expected anyone to actually die in this war but despite their best intentions there were people dying by the hundreds on each side the ones who wanted this outcome were the warmongers and those with darker ambitions as well as those with darker impulses.
The stand outs on the devil side are Sirsechs Gremory Grayfia Lucifage Venalena Bael Yubelluna Morningstar Lucifer Morningstar and the 4 maous on the angel side is Michael Gabriel Uriel God and some seraphs on the fallen angel side there's Kokabiel Azazel Baraquiel and some 4 winged fallen angels despite these things they were hesitant to really get into the real war because they could feel 2 huge powers making their way to them getting closer and closer everyday in fact these powers equaled the heavy hitters in each army at full strength.
Acknowledging this fact was not an easy pill to swallow but eventually the day came when they met the 2 powers it was 2 huge dragons one was white and blue the other was red and green they immediately stopped fighting upon sensing the energies around them they smirked at each other then started attacking as many of the 3 factions as they could taking out several of the weaker warriors who tried putting up a fight they even tried combining holy/devil attacks plus combining elemental attacks it didn't work the dragons were too strong.
The 3 armies quickly decided to make a quick truce to bring down the 2 dragons it took everything they had but they did it God was able to turn them into sacred gears but their bodies remained then fused together then vanished as if they never existed the last of their power knowledge went to the person they found worthy of it although they also went and grabbed one last dragon before vanishing forever it was someone who was as powerful as both of them put together but he was only good at 2 things illusions and barriers his attacks were only half as good as them but he taught them to be dragons that should be enough for who they have chosen.
After resting and getting back to full strength they decided to fight each other instead of putting it off any longer they make plans on how to proceed which is going well things have been improving also they test out a technique it works and they're able to steal the knowledge speed strength and power from the dead however they are only using one person per person so the power doesn't overwhelm them and it will only last until they master it which is more than enough time for them to get back into the fray it's not lost on them how wrong this feels but they only use this technique on their weakest warriors in fact Lucifer casts it on all 3 factions surprising everyone in the other 2 factions camp when everyone of their weaker warriors power levels shot up to high tier mid class devil almost high class devil.
The weaker warriors went off to combat each started off by trading blows impressed with their increased abilities they continue to push their limits to see how far this power up goes not even bothering to kill their foes just injure also trading energy blasts then demonic/light weapons as well as elemental attacks each attack just cancels each other out even teaming up it doesn't matter each person is only slightly stronger than the other so they can't over power an attack even if they wanted to they simply lack the power although now this boost will be permanent but after they surpassed it but now they lack the energy to even throw a punch.
Everyone takes their men back to camp heals them then once they're back to full strength Lucifer uses the technique again but gives every faction's warriors from their weakest to their mid level warriors a total of 8 dead people's energy speed strength and knowledge the results were explosive those fighters reached high class devil levels almost reaching ultimate class the leaders of the other 2 factions couldn't believe what they were feeling coming from their weakest soldiers they eye Lucifer wondering what he's planning as this is the second time he's done this God however knew what his son was doing and approved at making the weaker soldiers stronger instead of the elite.
Despite increasing their abilities one hundred fold it doesn't matter the war just made everyone want to see who's stronger and to put their subordinates in place however this changes when a really powerful foe drops into the battle field it was a human looking girl with an average body red eyes pink hair with black streaks running through dressed in a red pink and black battle dress with light armor on wearing greaves and gauntlets she started attacking all 3 faction's army until they took her seriously however this was the most powerful foe that they have ever faced.
The fight was lengthy they were trading blows with this mystery warrior as best as they could while also blasting her with energy attacks throwing light spears and elemental attacks but nothing was working except when some grunts decided to combine their powers for launching every element at once plus demon and light energies it actually hur her which made everyone else do the same but even doing that there was still losses on every side when they finally wounded her enough to get her to talk God asks "why did you attack us we have never met you before".
She laughs then says"I was asleep for centuries but i was awoken by the massive amount of power i felt also i wanted to see how strong these group of warriors were considering their massive power levels but sadly i'm quite disappointed i was afraid that no one would have caught on to my little game but one of you did in fact he sensed me before i even got here" she points at Lucifer when she says that this shocks everyone because nobody felt her coming until she was here in the battlefield also they were wondering if it was because they were not used to sensing powers this massive.
God takes a real good look at her then immediately understands that if she were to use her true power everyone here including him and his son would die they ask her if she wants to die be sealed away or have her powers stripped she says sealed away but not in a sacred gear but in a statue that traps me in a separate dimension for all eternity they agree with her request take her to where she wants she tells them what to do they follow the ritual exactly then she gets sealed away but they had to sacrifice 666 soldiers from each army after that they decide to take care of their dead and end the war.
The most notable of the fallen is the 4 satans or maous also every person plotting to kill God and Lucifer in their armies were slain they knew who they were which is why they put them forth to attack the mysterious warrior or seal her away those who were plotting couldn't help but work together for the sake of the universe at large little did they know that it would lead to their demise and forever silence any plans that they might have after that everyone signed a nonaggression treaty so they wouldn't kill each other on sight next they went home to pick up the pieces.
Meanwhile back on earth Naruto has finally gotten used to the cold so he decides to train in earnest by mastering his chakra as well as those strange powers he feels inside of him he creates enough clones to over populate the planet but he knows that they will help him accelerate his training immensely he separates them into 9 groups:
Group 1 : Chakra control
Group 2 : Taijutsu
Group 3 : Genjutsu
Group 4 : Fuinjutsu
Group 5 : Kenjutsu
Group 6 : Spying on the world at large covertly going to every country all over the world
Group 7 : Ninjutsu
Group 8 : Fallen Angel Training
Group 9 : Devil Training
Group 6 left right away not before he made them indestructible also they were given enough chakra for 4 S rank jutsu but he put a seal on them to hide their power as well as a separate seal that when activated will not only make them invisible but will eliminate their heartbeats scent any sounds they might make and their foot prints after that they snuck into every country and continent on earth learning everything that they can about this place while doing so some clones find a library in the desert they keep watch over it for days but no one else has found it so they sneak inside then seal away every document and artifact inside the library.
Some of the clones come across a medieval looking place with lots of guys in armor they sneak through the castle unseen find every document they can as well as books they do this in every kingdom that is allied or against the one called Camelot they also save the king from certain death by killing those who were going to betray him however they left before the real threat could be taken care of next they go to various countries steal various books and scrolls then come back to their boss to deliver what they found they see that he's training so they put everything in his library then dispel giving him memories of everything that they have done and seen.
Group 1 is working on mastering chakra control each group of clones in this group is doing a different exercise each one is at a different level not just in how much chakra is required for the technique but the difficulty as well the groups are working on:
Leaf exercise
Tree climbing
Water walking
Kunai balancing
Kunai spinning
Leaf spinning
Leaf sticking
Leaf sliding
Chakra flow
Chakra scalpels
Shape manipulation
Change in chakra nature
These group of clones are pushing themselves to completely master these exercises without needing any help from the others or receiving tips from their boss while he's trying to unlock his new powers they know that trying to unlock a new energy or new power at all is not easy and will take everything he has to do it otherwise they know that he would have done this training by himself no matter how long it took it takes them a few years to master every stage of chakra control perfectly once their job is done they dispel themselves.
Group 2 works on trying to combine every fighting style the ninja world has but so far each one just combines into 5 separate fighting styles called the element fist it's fighting styles based on the 5 elements fire water earth air and lightning once they successfully combine the rest of the styles with those 5 it makes everything a lot easier although combining all 5 styles is the hardest thing that they have ever tried to do it takes a few decades but they do it then dispel.
Group 3 works on mastering every genjutsu there is without needing hand seals just looking at their opponent or thinking about it while holding the hand sign for snake or ox or ram is enough to do most of the jutsu that they know except one it's too difficult to cast with only one hand seal or with thought in fact it's even too powerful for them to cast but they master every other one there is then they dispel.
Group 4 works on mastering fuinjutsu or seals they start from various stages and levels to get the maximum results they practice every type of seal there is until they master it then they combine seals while doing this they figured out that their boss has something buried deep within him that is desperately trying to get out or awaken so they do that on accident which makes a huge surge of power go through all of the clones and their boss when not only his hybrid powers were awakened but his sacred gear as well after the energy dissipates they see what looks like a burnt orange glove with black stripes with a rainbow jewel in the center it stops at his wrist kinda looks like a bug at first until they see it has spikes coming from it.
After that the fuinjutsu clones carefully went back to their training until they mastered everything once they did they dispelled after they dispelled he got their memories at first he was a little annoyed but grateful that they messed with a seal otherwise this might not have happened for centuries or not at all after he gets used to the new power flowing through him he decides to get the dispelled clones memories in order so he can use them in his training later while he's doing that the rest of his clones are continuing their training so their boss will be able to master everything.
Group 5 is working on kenjutsu they try to do the same thing as group 2 make an ultimate style they come across the same problem as the taijutsu clones no matter what style they use or combine together they keep coming back to the element blade style so they just go with the same theory as the taijutsu clones it takes them 100 years to master that style completely after they made sure that there wasn't any flaws in the style they dispelled once Naruto went over the memories he was impressed with what he learned from this group he continues meditating so he can focus on the barrier he set up when he first got here and on the memories from the dispelled clones.
Group 7 is working on mastering every justsu there is from F rank to A rank it takes them forever to not only learn each jutsu but to master them so well that they can do one handed seals and cast two jutsu at the same time or cast them with their feet mouths or eyes it takes everything they have to master them to no hand seals at all especially the elemental ones are really hard for them to master up to the final level or dual casting but they do it it takes them 200 years but they do it once they're sure that they have mastered every jutsu they were given they dispel.
Group 8 works on mastering the Fallen Angel abilities it seems that they have various abilities and the training goes to various levels:
Level 1 : heightened senses
Level 2 : increased speed and strength
Level 3 : flight
Level 4 : channeling holy energy
Level 5 : shape manipulation
Level 6 : object creation
Level 7 : magic
Level 8 : elemental attribute training
Each few hundred of clones worked on training these as best as they could but they could only train on levels 4 - 8 once they figured that out the rest of the clones split up into groups and started working on mastering those levels as best as they could it was slow going but they were getting the hang of it learning how to use this new energy was the hardest thing that they have ever done but they know that once this done their boss will be the strongest being in the whole world that nobody will be able to stop him they finally master what they were working on once they work on combining this weird energy with their chakra and master that they dispel.
Group 9 is working on mastering the Devil abilities like the previous group they figure out that these abilities have different levels to them however these levels were quite different but similar to the other races levels they study the material carefully as not to make any mistakes when trying to identify the exact levels and what they need to learn:
Level 1 : enhanced senses
Level 2 : increased speed and strength
Level 3 : flight
Level 4 : channeling demonic energy
Level 5 : shape manipulation
Level 6 : object creation
Level 7 : magic
Level 8 : elemental attribute training
This group of clones did the same as the previous only working on levels 4 - 8 it was a really tough process but they were able to pull it off however they ran into a challenge merging chakra with the fallen angel energy as well as devil energy was the hardest things these clones has tried to do but they did it in just 200 years once they make sure that there are no issues they dispel while this was going on Naruto has had several clones going over everything that was brought back by the group 6 clones it takes them 30 years to read through everything once their sure that they translated everything right they dispel.
Naruto sorts through the memories carefully to make sure that they are in order and that he doesn't forget anything once he's sure that he got everything he reads everything for himself that was found it takes awhile most of it was stuff about the town or country that they got it from or myths and legends other stuff was military maps and battle plans or information on various subjects one of which is magic he immediately begins every culture's version of magic until he masters it after that he creates some clones then tries to create a new version of the lightning armor.
One set of clones are working on wind armor while the other is working on fire armor Naruto himself is working on the lightning armor he plans to combine them then combine this technique with his new powers the work on it for years it takes everything they have to just do the elemental armors without anything going wrong they finally accomplish it but now the hard part is trying to combine them he has the clones do that while he tries to conjour a holy demon full body armor to combine with the elemental one when its complete he's going to call it " Juggernaut armor" the thing he forms is a ninja with samurai armor on it also it's orange after that he gets with his clones and they successfully combine everything together.
He tests the armor extensively making sure that there were no problems even with energy drain or stamina drain he also used his clones to to attack him with various attacks from all 3 different types of energy after some trial and error it was learned that with enough energy it could stop physical attacks and even blades but the ratio had to be carefully kept in check as was the case when trying to defend against all 3 types of attacks simultaneously also he learned that the same elements that made it up could be used to attack his clones with various attacks but nothing above a B rank or it would fall apart.
There's just 2 things left to train in however he knows that the second he trains in one of them he'll never be left alone again by the supernatural community he decides to train in his sacred gear leaving his sage training for last once he starts meditating again he finds himself in a void with an orange and black dragon with rainbow eyes he looks at Naruto then in one instant they see each other's memories and see the other's whole life up until now the dragon says" i'm quite impressed that you've made yourself so powerful in such a short time however we both know that you don't know where you stand in terms of power compared to the others but with my abilities it won't matter because you'll surpass them all now there's just the matter of learning them".
Naruto asks what kind of powers do you have the dragon says first my name is Absalom next the i have a list of powers:
divide
boost
transfer
absorb
reflect
barrier
illusion
sword craft
persuasion/telepathy
Naruto is intrigued by the list of powers Absalom has but sees that several of them are locked away until his sacred gear evolves into it's 4th evolution but the ones he can use now are :
persuasion/telepathy
reflect
illusion
Naruto begins training these abilities right away against his clones he uses the persuasion ability to convince them to go out and build him an empire that will make every other business man cry in their graves they go do what he says he laughs evily then he gets an idea he asks Absalom what year it is he says that it's the year 1000 AD he thinks that he can master his mind reading on actual humans which Absalom agrees with but warns him about how some supernaturals can use mind powers as well Naruto packs up all of his scrolls and belongings then gets dressed in normal clothes that people wear a light cloth shirt cloth pants and brown shoes.
he travels all the way to Europe he has a feeling that something is going to happen soon that will benefit him greatly if he stays in Europe so goes from town to town and country to country trying out his telepathy on everyone he sees he can read their every thought with no problem with practice he can even implant thoughts into their heads also he has learned a new ability telekinesis it's slow going but he's able to get it up the same level as his telepathy however that's where his mental training must come to a halt until he grows stronger he can improve the powers he has but he can't learn anymore he uses the telekinesis for earning money in disguise.
No human has ever seen his true face in fact they never will unless he has to but that may likely never happen next he works on his persuasion ability he's able to get things for free or take over their businesses without much trouble he does this until he can convince them to do anything the same with his other 2 abilities he slowly acquires a number of businesses in various different fields he even takes over the criminal underworld in every city in every country no crime happens without his say so those crime families still exist they just answer to him the same with the gangs they still exist they just don't move without his say so.
