Three Year Latter (Age 8)
Little has changed physically with the twins other than on their foreheads now sits a lavender colored diamond mark, and they now stand at a slightly taller than average four foot seven inches for Naruto and 4 foot six inches for Naruko.
Naruto has lorded that one inch over her head ever since.
In terms of training over that last three years, due to Tsunade's fear of losing them, she forbade them from using their Mokuton till they received the sage training.
So to keep them occupied and relatively content with their training, she hammered into their according to Tsunade "Thick, stubborn, and Impation minds" the arts of chakra control, and medical ninjutsu.
In these arst the biggest differences between the two began to show, Naruto has slightly worse control compared to Naruko, but he has slightly more patience for the medical arts.
In the end though to call them anything less than prodigies would be a mistake, while both of them would rather meet their enemies head on and throw explosive jutsus one after another at them, they both rather forcibly (from Tsunade's fist hitting their heads) began to understand the value of the medical arts, and even patience.
At their young age they may not be able to perform complicated surgeries, but for battlefield life saving first aid, that they can do; no standard battlefield injury can't be held by the two, broken bones, severed muscles and punctured organs, all in a day's work for the two.
Tsunade did notice though nether truly had the patience to become a dedicated medic-nin, so with their now medic level chakra control, lower Biju level chakra reserves and stamina, and with their now monster like strength, while still not at her own level they can still bring down a wall or three if they want, she determined they were ready for the sage training.
"Alright you three, behave yourselves with the toads" Tsunade said looking at her husband, and two grandchildren.
"We will send you a letter every Month but it's impossible to tell how long we will be gone." Jiraiya says.
"I know, I'm just worried." Tsunade replies sadly.
"Alight Pa, lets go." Jiraiya says looking down at the old toad.
"Reverse Summoning Jutsu." Pa says, and in four puffs of smoke they are all gone.
Mount Myoboku First Month.
With the old toad, and Jiraiya explaining nature energy and sage mode to the twins, they quickly grasped the concept and began drawing in nature energy with the aid of a few shadow clones and the toad oil.
The hardest part of them was ironically not the act of feeling the energy, drawing it in or even controlling it, the problem for them was drawing in enough of it to enter even a complete sage mode.
Due to their massive reserves even with the aid of oil and clones it took nearly 4 hours for them to enter an incomplete sage mode by the end of the Month.
Witch still astounded both of their teachers.
During this Month they also met with Gerotora and received the key to their seal, although after talking with the Kyuubi they agreed to wait till they were done with their sage training. They agreed to this because having even more chakra in their systems would only make the training that much harder, while also making it easier for them in the future to control the kyuubi's even more stubborn chakra.
Mount Myoboku Second Month.
The second Month was significantly less remarkable, it was basically the twins meditating, working on reducing the time it took to draw the energy in.
With both the oil and clones they reduced it to an hour, although in this Month Jiraiya also joined them, working on reducing the time for him as well getting it down to about five minutes on his own.
Mount Myoboku Third Month.
This Month saw significantly more progress for the twins, in this Month they reduced the time to just five minutes with clones and oil before they made the trip to the balancing stone peaks to begin doing it without the use of oil.
This took them back to the two hour mark but with less clones due to the space they considered this a win.
They also ran out of food they brought and had to begin eating ma's cooking with their reactions to get them more than a few smacks on the head with a rolling pin.
Mount Myoboku Fourth Month.
In this Month all three of our sage mode trainees were capable of entering sage mode in less than a minute without the use of clones, oil or the toad elders.
They then also began refining their use of natural energy and Pa declared the twins to be the first perfect toad sages since the Sage of six Paths himself.
And thus the most painful part of the training began Frag Kata, while poor Jiraiya still had to meditate and work on his control which made him pout for the rest of the Month.
Mount Myoboku Fifth Month.
During this Month Jiraiya set off with new motivation (to not be left behind by his grandchildren) and also became a perfect sage.
Sage mode combined with the twins' already monstrous chakra enhanced strength, went from making small creators to completely altering the terrain on a massive scale beyond that of even Tsunade.
Their sensing ability also went from a few dozen miles to spanning nearly the entire fire country.
Even Jiraiya could now see nearly a hundred miles with his sage mode.
They then began work on the final thing they came here for; learning to use Mokuton to its true limits but first they needed to master Doton and Suiton.
Mount Myoboku Sixth Month.
This Month was the most fun for the twin practically non stop ninjutsu training, they mastered their uses of Doton, Suiton, and beginning in Futon. They packed on no less than 123 new justus of the following ranks: 72 C-ranks, 38 B-ranks, 12 A-ranks, and 1 S-rank.
In Jiraiya's own words "You have nearly matched me in the use of ninjutsu."
Needless to say the next Month when they begin to master Mokuton, would be a Month to remember.
Mount Myoboku Seventh Month
This Month was remarkable, with the scrolls left behind by Hashirama they began their Mokuton training. The only technique they could not use was was the 'True several Thousand Hands' Jutsu
The final day they would spend here was going to be something special for the twins; they were going to get a no holds bar spar with both of their grandparents with one exception, they would be alone, meaning no summoning for them.
"So this is the famous land of the toads you always told me about. It is beautiful" Tsunade remarks upon being brought to Mount Myoboku.
"Welcome Tsunade, it is very rare for a non toad summoner to come here, but at the behest of all three of our summoners we have allowed you here for the day." Pa states
"I thank you for the opportunity to be here" Tsunade responds
"GRANDMA" The twins shout before they "accidentally" tackle Tsunade with a chakra enhanced jump from behind, knocking her to the ground.
"Was that really necessary brats?" she responds while hitting them on the head once she stands back up; after this she pulls them into a very tight hug before the response as well with all three enhancing their strength with chakra subconsciously.
"As much as I want to join that hug I don't feel like being tuned into paste for doing it" Jiraiya states looking at the three while shaking his head in disbelief at their antics.
They let go of the hug before Tsunade hugged Jiraiya saying "I've missed you too pervert."
"I'm not a pervert, I'm a super pervert,'' he corrects her, for that she bashes him over the head.
"Alright i brought lunch so let's get caught up over some ramen" tsunade states pulling out a sealing scroll.
The twins instantly start drooling while dreamily stating "Ramen"
After lunch
"Alright, let's do this" the twins say together
"So Jiraiya since you purposely left me out of the loop for their training what should I expect?" Tsunade asks.
"Anything and everything. If we hold back in the slightest they will absolutely annihilate us." Jiraiya states seriously as he closes his eyes and enters sage mode in about 8 seconds.
"I see you got better at sage mode, I like the look, no more warts or webbed hands." Tsunade states watching Jiraiya
"But they are still better." he replies looking at the twins.
As Tsunade looks back to the twins she watches them close their eyes for less than a second and reopen them with the marks of a sage around their eyes; as they do this even Tsunade who isn't a sensor can feel the difference that it made in them.
"Holy shit" she replies.
"Everyone ready?" Pa asks as he and Ma get onto Jiraiya's Shoulders.
"Yeah lets do this" The Twins respond together.
"BEGIN" Gamabunta shouts starting the spar.
All four opponents dash towards each other and engage in a fast paced taijutsu battle with Jiraiya and Naruto Duking it out, and Naruko and Tsunade Trading blows.
Every Punch is met with a block or a dodge that continues for a few seconds before Naruko massively increases the chakra in her arm before she counters her grandmother's punch with her own witch creates a massive shock wave and blasts Tsunade back into a rock face behind her.
"That hurt young lady you are asking for a beating now."
"Strength of One-Hundred Seal: Release" she shouts as black marks cover her forehead and she climbs out of the rock only to be met by Jiraiya flying into her face who was quickly double teamed by the twins and forcefully thrown into her.
"Clearly we are not going to win a battle of taijutsu with them, they are faster than you and stronger than me, even with my chakra enhancement that punch still broke my wrist and dislocated my shoulder. Tsunade remarks.
"Shinobi Battles skill number 2" Naruko starts "Ninjutsu" Naruto says with a smirk
"Sage Art: Water style: Multiple water dragon bombs" 12 Dragon head shaped projectiles form around Naruko from thin air, and begin flying towards Tsunade and Jiraiya.
"Sage Art: Wind style: Multiple air bullets" Naruto lets a dozen air bullets slam into the back of the water bombs drastically increasing their speed and strength.
"Earth style: Multiple earth walls" Both Jiraiya and Tsunade Say together in response to the rapidly approaching sage and wind enhanced water bombs.
As the walls are still forming The water bombs slam into the walls one after another vaporizing all of the walls forcing Jiraiya and Tsunade To jump away from the last two bombs.
"Shall we end this" Naruto says to Naruko
"We shall" She responds and the bump fists before slamming their hand together and saying "Sage Art: Mokuton: Wood Golem" and "Sage Art: Mokuton: Twin Wood Dragon"
As they say this the ground starts rumbling underneath them and a gigantic wooden golem towering over even gamabunta emerges with two wooden Dragon Wrapping around it with their heads resting on the golem's shoulders..
"Holy shit, they never showed this in training, not to this scale anyways" Jiraiya states in awe of his two grandkids.
"Grandpa used this to beat Madara with the Kyuubi, we have nothing to stop this."
"Will you surrender" the twins ask practically taunting them in the process.
Jiraiya and Tsunade look at each other before saying "One last attack"
Tsunade begins to pump as much of the chakra as she can into Jiraiya who begins to form a massive sage enhancing rasengan above his head.
Ma speaks up "Isn't this a little too much for a spar"
"Those two wouldnt know the word restraint if it hit them over the head" Pa responds
Now with the rasengan formed Tsunade grabs Jiraiya before asking "You ready?"
"Its now or never" he replies
In response she throws him with all of her strength straight at the wooden golem, in response the twin dragons fly forwards charging straight into rasengan that is now easily the size of the toad chief.
When the two collide a massive explosion forms from the two attacks colliding as the dragons are shredded by the rasengan before it disappears.
When the smoke clears the Twins golem is still standing and Jiraiya is on the ground breathing hard now out of sage mode.
"One down one too go" the twins state in glee.
When they finish the massive golem charges with its fist drawn back straight towards Tsunade.
Tsunade, seeing it as a challenge, cocks her own fist back, charging it with the last of her seals chakra and jumps straight at the golem's fist.
When the two fist meet a massive shock wave rips through Mount Myoboku, before Tsunade gets pushed back by the golem before she smacks into the ground and falls into unconsciousness.
"Winner the twins" Gamabunta shouts from across the valley they fought in.
The golem disappears back into the ground as they grab their grandparents before they begin to heal their wounds, which mostly constitute broken bones.
After a few hours both Jiraiya and Tsunade have awoken.
"To think, they beat both of us without breaking a sweat." Jiraiya says to her.
"Yeah, they didn't even need the sharingan to do it either." she replies.
"It's good to see you awake, Grandma, and the reason we didn't use it is simple, sage mode already enhances our senses and begins to give us a headache, with the sharingan we can only do about ten minutes or so before we pass out from sensory overload." Naruto responds.
"That makes sense, where is your sister?" Tsunade asks
"She is helping Ma with dinner, she was going to make her famous grub soup but we thought a more sensible chicken salad would be more appropriate.
"Are you telling me you ate toad food for seven months while you were here?" tsunade asked
"No, only four; although after a while you just get used to it." Naruto replied.
Tsunade shakes her head and says "I have no idea how you would."
"So what are we going to do now?" Naruto asks curiously.
"Well, your training in taijutsu and ninjutsu is basically complete, your medical ninjutsu is better than you two will likely ever need, and your kenjutsu is alright. The next step would be either Kenjutsu which means we would have to find you a teacher since neither of us is very skilled or we begin working on the next fuinjutsu level." Jiraiya states.
"Hmmm with now having mastered wind, Kenjutsu is tempting but, both of us have wanted to master our father's other technique for some time." Naruto states.
"Well right now you two are second level seal masters, to even start on space time ninjutsu you would need to be at least level 9, and likely to do that technique level 10." Jiraiya states.
"How long do you think that would take?" Naruko who just entered asked.
"Well considering you two learned the first two levels in 6 months, if you worked your asses off with the help of some shadow clones, likely by the time you two go back for the final year at the academy in a little over 3 years." Jiraiya responds.
"But that won't be the only thing you will be working on, while your clones work with Him on seals you will be working with me on your physical training and working on using the sharingan with sage mode as well." Tsunade interjects.
"Why do we have to work on our physical strength? We are already stronger than you" Naruko asks.
"While sage mode and chakra enhanced strength and speed are nice and all, you will get more out of them if you are naturally stronger and faster." Tsunade answers.
"Alright I guess" Naruto replies, not looking forward to his grandmother's physical workouts.
"Don't forget now we have to work on using the kyuubi's chakra as well" Naruko reminds everyone.
A week after leaving Myoboku
"I think it's time to open the seal; the Kyuubi doesn't deserve to be locked up any longer than he has to." Naruko says during lunch.
"I agree, it must suck to be locked up for something you didn't do willingly" Naruto cuts in.
"Alright but if he shows any hostile intent, Naruto I want you to use your Mokuton to hold him back and Naruko to relock the seal." Tsunade states seriously.
"I don't think he will do anything but it never hurts to be careful," Jiraiya says.
Inside the mindscape
As the twins approach the familiar red doors, they speak up to the kyuubi, "are you ready to be free?"
"Only if you think you are ready kits." The Kyuubi speaks, raising his head from his paws and raises into a sitting position.
Both twins' right hands begin to glow with kanji and Naruto begins by twisting his hand and the swirl pattern on the lock begins to move and is then half unlocked and a warm feeling begins to pass over both twins.
Naruko continues, following suit and the second half of the lock twists away.
The Kyubbi then gently nudges the doors open, walks forward towards the twins then proceeds to curl up in a ball in front of them.
The twins then jump up onto the kyuubi's paw and sit down resting their heads against his.
A soft womanly voice then speaks up, "It's nice to see you again Kurama, and even better to see you again my children"
At this both twins jump to their feet and in front of them is a beautiful redhead they both instantly recognize.
"Mother" they whisper in a shaky voice before they bolt down and tackle her into a hug faster than she can see.
"You two are so much like your father, it's scary" Kushina responds, getting hugged tighter.
"That speed with mothers strength, that is a terrifying combo; although if you want to continue to talk you should probably let up before you crush me." She states struggling to breath from the force.
Both twins suddenly let go of their mother in fear of losing this precious time with her.
"Where to begin, well let's go get a comfy seat, come" as she finishes she hops up onto the kyuubi and lands on his head before gently stroking his hair.
When the twins land next to her they also begin stroking his hair, and the kyuubi purrs gently from their touch.
Naruto speaks first "Why did you call the kyuubi Kurama, mom?
"Well that's simple it is his name after all." Kushina replies with a smile.
Naruko turns towards the kyuubi, "Why did you not tell us you had a proper name?"
The kyuubi replies "I normally tell my hosts when they begin to train with my chakra, but I will ask that you keep it to yourselves, our names are very important to us biju; only one mortal has had the privilege to know all nine of our names, our father or as you would know him the Sage of Sixth Paths. But we can talk later for now, spend this time with your mother, kits."
Naruko turns to her mother and asks, "I always wondered how you and dad met and fell in love"
"Well, I fell in love with him after he rescued me when Kumo tried to kidnap me for Kurama. However you thick headed father could not fathom that the girl he had a crush on could like him back." she states.
"Well how did you get together?'' Naruto asks.
Kurama speaks up "She'll never tell you so I will, one day after a mission your mother pinned him to a wall and practically shoved her tongue down his throat to get him to notice she loved him back."
"KURAMA WE AGREED TO NOT TALK ABOUT THAT!" Kushina yells, hitting Kurama on the head.
"She continues to explain in somewhat vague details about her and Minato's relationship as well as other major points in her life."
"Now that I have told you about my life, how about you tell me about yours?"
The twins take turns explaining how they get to see so much of the world and about their training and even about their spar with their grandparents.
"I'm glad to see you take your training seriously, and fighting to protect each other and your grandparents is a remarkable goal. Now my time is mostly up and I have to go, but promise me this, Naruto if you find a girl you love and she loves you back no matter who they are you have my blessing, the same goes for you Naruko, find a wonderful husband." Kushina finishes with tears rolling down her face
She hugs her children tightly and says "Make sure to give me plenty of grandchildren in the future, and know me and your father will be watching you. Now my precious children my time is at an end, Tell your grandparents thank you for me, despite their faults they have raised you well. I love you and always will, goodbye."
As they look at their mother fade away they unconsciously activate their sharingans, as she turns white and fades away forever, they begin to cry.
As they do so their eyes begin to spin and pulse revealing In Naruto's a 4 bladed design that then curves back into the next spike (Think Obitos but 4 pointed) and in Naruko's a sleek 4 pointed shuriken (Itachi's but 4 pointes).
With Kurama noticing their eyes he thinks 'Was the emotional stress of losing their mother again enough; I guess I'll have to wait for them to wake up to explain some things before they leave.'
Outside the mindscape
"It's been nearly 3 hours shouldn't they have come back by now?" Jiraiya asks worriedly as he looks at the unconscious forms of his grandchildren.
"Their minds have finally calmed down but there was a rush of chakra to their eyes beforehand, it appears they are just asleep now" Tsunade informs him.
"Is there any sign of the kyuubi's influence?" He asks.
"After the initial increased flow of its chakra there have been no changes. We are just going to have to wait and see."
4 Hours later Back In the Mindscape
Naruto's eyes begin to flutter open and he suddenly bolts up and shotus. "MOM"
"She's gone kit, you passed out after she left, gently try and wake your sister; I have some things to explain before you go back to your grandparents."
He looks down at his sleeping sister and thinks 'She looks so peaceful asleep like that'
He gently rubs her shoulder, softly saying "Naruko, you need to wake up."
Her eyes begin to flutter and when she sees him she jumps into him and says "Mom, she's gone" on the verge of crying.
"I know, but she wouldn't want to see us like this, ok both her and dad cheated death to have a few hours with us that's something most orphans never get."
"I know but it still hurts" she replies letting go of him.
"Come on, Kurama says she has something to explain before we go."
Kurama Speaks up "I'll be brief, when you saw your mom leave the emotional stress awoke the next stage of your sharingan."
"I thought when we had three tomos it was fully evolved." Naruko speaks up.
"Yes and no, it's a fully evolved base sharingan, what you unlocked is called the mangekyo sharingan, It will give you two powers unique to each caster and a third that they all share, one from your left, one from your right. Each of these is a power jutsu unrivaled in their field.
Take amaterasu the pinnacle of fire jutsu capable of burning anything even other flames or tsukuyomi the Strongest illusionary genjutsu 3 days in it are just 3 seconds in real time, the caster has complete control of the world they make and not even pain can break it. And finally the ultimate defence of the sharingan using both eyes, one can create a spectral warrior called the susanoo around them to both attack and defend."
"This sounds amazing, too good to be true so I assume there are drawbacks to the techniques?" Naruto states.
"Correct, there are 3 drawbacks to these abilities, one the massive chakra cost but for you two this won't be a problem, the second is the backlash to the body they rapidly tire the body, and the third and most severe of all, every time you use these techniques, you will lose a portion of your vision till you go blind."
"So we should only use these as a last resort then since we don't want to go blind." Naruko states.
"Yes and No, there is a way to gain your sight back and the decay is gradual so if you only use it once at a time and allow your eyes to recover you won't go blind any time soon."
"You said there is a way to get your sight back, what is it?" Naruto asks curiously.
"From what I know, you have to trade eyes with another mangekyo from one closely related to you."
"So we could just trade eyes with each other, problem solved." Naruko states thinking about the awesome powers she could get.
"While yes that is an option, there is a chance the eyes won't take and you will remain blind, however if it needs to be done with both me and your grandmother as well as your Senju genes, it shouldn't be much of a problem. It will also drastically reduce the other two drawbacks as well just not entirely." Kurama replies.
"Now go, your grandparents are about to lose it."
The dark mindscape begins to fade and the framillier sight of their grandparents fills their vision.
"Their minds became active again; they are likely still talking to it." Tsunade states.
"They should be back by now. Something must be wrong, it's been nearly 7 hours." Jiraiya states.
"Grandpa it's fine we are back," Naruko speaks up.
Both kids are pulled into a tight hug by their grandparents when Tsunade speaks "What took so long it's night time now.
"We met our mother," Naruto says sadly.
"That's amazing, why are you two so sad." Jiraiya states.
"It's hard to say goodbye" Naruko says
"I understand, it was hard for me to say goodbye as well." Tsunade remarks thinking back on when she had to say goodbye.
"That's not all though according to the fox the stress awoke the next stage of our sharingan." Naruto states in a slightly more upbeat tone.
"The mangekyo" Tsunade states.
"What is that, i thought three tomoes was the max" Jiraiya asks confused
"According to the fox, the mangekyo grants three powerful abilities two that are different for each caster, and one they all share called the susanoo."
"But from what my grandfather told me it comes at a cost, the cost of your sight." Tsunade cuts in.
"So in other words it's a last resort for them," Jiraiya states firmly.
"Yes and no," Naruko replies. "The fox said that by exchanging eyes we can achieve eternal light" Naruto finishes.
"My Grandfather said Madara did that when he lost his sight as well." Tsunade remarks.
"So I guess we train them till we have lost most of our sight then exchange eyes" Naruto says and Naruko nods in agreement.
"Ok but first it's past your bedtime you go off you go." Tsunade states.
One year Later (Age 9 almost 10)
"Alright you two deactivate the resistance seals, lets see how fast you two are now." Tsunade commands.
"Resistance Seals: Release" the twins shout in unison.
"Alright here is the rules for this session, until lunch you need to dodge the balls, no sharingan no sage mode no chakra enhanced speed period end of story.
"Shadow clone jutsu" Tsunade states and now 10 of her surround the twins with a pile of dodge balls behind each one of them.
She begins
"3"
"2"
"1"
"Dodge"
Immediately the twins begin swerving and dodging as the balls are thrown at supersonic speeds by their grandmothers clones from all sides. Getting hit by any of the balls will result in the bones shattering wherever they hit as well as getting thrown into one of the clones who will just punch them back into the center of the arena adding more pain to the suffering.
Lunch time
"Congratulations to you two, you dodged every ball for the last 4 hours." Tsunade dispels her clones and the twins finally stop moving.
This reveals both of them are only slightly out of breath and not even very sweaty either.
"And on top of that you are not even worn out either, there isn't much more I can help you with other than now adding levels of your resistance seal to the training."
"Does this mean we can have ramen for lunch" The twins ask in excitement.
"Yes, but I think it's also time you work with your tennant on controlling his chakra and then your mangekyo as well." Tsunade states.
Suddenly both twins grab their heads for a second before they smirk and fist bump.
Jiraiya then walks into the small clearing.
"Congratulations, you two have reached the 5th level of sealing barely ever touching a brush personally." Jiraiya states slightly annoyedly.
"Well" Tsunade begins "the 5th level is on barriers and chakra suppression seals right." She asks, rubbing her chin.
The twins reply "yeah why."
"Well perhaps you should put your skills to the test and set up your own barriers for your training with the kyuubi." Tsunade replies.
"That would be a good test, and do you think they are ready?" Jiraiya asks with concern evident in his voice.
"If their bodys are not strong enough now I don't think they ever will be" She replies.
"But first let's have some lunch." and a pair of Tsunade clones walk out of the house with a dozen bowls of ramen.
Faster than Tsunade, her clones or Jiraiya can react. All 12 bowls of ramen are gone and this time there was not even a visible blur of blond.
"Dam they are fast, at this point the only ones faster would be Minato with his Hirashin and the Raikage with his lightning armor." Jiraiya states once again in awe at his grandkids.
"What kind of monsters have we raised, there was no sharingan, no chakra enhanced speed and no sage mode and they are still that fast." Tsunade says shaking her head for what feels like the 10 millionth time to the blonds.
"Grandma is there more?" the twins ask in unison suddenly looking straight at her with the infamous puppy dog eyes.
"Yes, but two bowls for us." she replies before the twins are gone again this time into the house.
After lunch
"Alright you two lets get started on these barriers, I'll set up one outside them just in case." Jiraiya states
After about 10 minutes of the twins drawing seals on the ground just inside the clearing, they say to each other "Ready, Sealing Technique: 3 Layered Chakra Barrier" and three colored domes appear over the clearing.
"Good use of level 4's multi layer sealing, so a chakra absorption barrier, an anti-sensing barrier and a sight barrier, it would appear all 3 are stable as well; you would make your parents proud, this should hide anything short of a full Biju." Jiraiya states proudly
"Thank you grandpa." The twins say together with a gigantic fox-like smile on their faces.
Reaching into their mind they say 'Ready Kurama?'
'I'm ready, let's take this slow, let me flow the chakra out and just try and keep it contained around you." Kurama responds.
The warm feeling of Kurama's chakra begins to flow through and around them, it makes them feel safe and protected, while also giving a sense of overwhelming strength.
'Looks good kits, let's try a one tailed cloak now' Kurama tells them through their minds.
To Tsunade and Jiraiya standing in the barrier the pressure went from intimidating to oppressive as the aura grew into the shape of a one tailed fox.
The twins open their eyes look at each other and say "Cool"
After adapting to the pressure Jiraiya says "Lets see how good your control is try and climb up that tree for a start."
As the twins put their first step on the tree they are violently thrown into their grandparents behind them, they are quickly shoved off of them as the kyuubi's chakra burned them.
"Well, that hurt, alright you two you know the drill." Tsunade says through her teeth as the chakra burns hurt like hell; she noticed as she began to try and heal herself that the progress was far slower than she expected.
"Damn that chakra is dence, it's hard to heal the damage." Tsunade states.
"Kids does that chakra hurt you at all to use?" she asks.
"No, quite the opposite it feels great, although the fox says when we drop it we will get hit with a wave of exhaustion till our bodys better adapt to it." Naruko responds.
"Well that's good at least, also it appears senjutsu counters the effects quite easily,". Jiraiya says as he released his sage mode to help heal the burns.
Naruto says "It makes sense it's like yin and yang, One is literally nature and the other is the power to destroy nature."
"I wonder what mixing the two would do, although we would need much larger quantities to match how much natural energy we bring in." Naruko states.
"Also it appears it's time for water walking." Tsunade remarks seeing them at the top.
1 ½ years later (Age just over 11 years)
"Amaterasu" Naruko shouts and her target tree busts into black flames.
"Good, I can finally cast it almost instantly now."
Naruko then looks back at the black flames "Blaze release: Black sword" The flames on the tree then form into a sword shape and Naruto walks up and grabs it, as he takes a few swings he says "Makes a nice sword but I think it's time I'm sick of everything being blurry" Naruto states.
"I agree let's get grandma," Naruko replies.
"You know she is going to be mad that we let it get this bad without telling her." He responds.
"Probably, but she never let us use them so of course we were just going to do it without her supervision, and grandpa would have told her anyways; lets go get our asses chewed out then not be able to see anything for a few days." she states with a sigh.
"Not like we need our eyes to function anyways, it will be a good refresher with sage mode too."
Inside their house
"YOU DID WHAT, AND NOW YOU ARE ALMOST BLIND WHAT THE HELL WERE YOU TWO THINKING" Tsunade screams, she would have punched them too if they didn't activate susanoo's rib cage to protect themselves.
"While I don't agree with you going behind our backs for this, I would still like to know how long you have been doing this."
Naruko answers "About and hour a week for the last 9 months"
"So are you telling me you kicked both of our asses half blind last month?" Jiraiya asks.
"Yes we did" Naruto answers.
"Alright you two, I have everything we need set up; can you tell the fox to not purge the anesthetic from you two otherwise this will hurt like hell." Tsunade says her anger is still obvious in her voice.
"He can't stop it but he can slow it, he says you will have about 4 hours till it wears off." Naruto answers.
"Ok, I should only need an hour." Tsunade replies.
3 days later
"Alright you two, it's time to take the bandages off and let us see if this worked." Tsunade says, her worry evident in her voice.
"Relax grandma the fox said we could have taken them off yesterday." Naruko says in a reassuring voice.
As both of them begin to remove the bandages from their eyes, when light hits them for the first time they blink as it was blinding at first, but after a moment they can see clearly for the first time in months.
"Well, how is it" Jiraiya asks while Tsunade holds her breath.
"It's great" Naruto starts, "Better than great I have never seen this clearly without the sharingan ever" Naruko cuts in.
"It was a success grandma congratulations on your first eye transplant." Naruto says.
"Now, Let's go outside and see what these eyes of yours can do." Naruko says towards her brother.
"Alright let's start with the basics" Naruto says.
"What can your eyes actually do, that you never told us?" Tsunade asks.
"Well with her right eye, Naruko, was able to cast and control the inextinguishable black flames of Amaterasu, capable of burning anything water, kyuubi and sage enhanced wood, other flames you name it.
Her left eye could cast the ultimate illusion called tsukuyomi, 3 days in the illusion is 3 seconds in the real world, the caster is god in that realm pain and suffering is given at their will; the only known way to dispel it is with another mangekyo, not even they kyuubi could break me out. Naruto explains.
"Naruto on the other hand had the ultimate coward's way out, he could turn his body intangible by transporting it to his own pocket dimension, with a technique called Kamui.
His other eye was capable of transporting other objects or people into his dimension. Earlier you already saw the basic stage of the third power we possess, it is called susanoo.
Jiraiya and Tsunade were left speechless for a few moments after their explanation.
Jiraiya asked "So since you swapped eyes are your powers swapped or what."
"That is what we are here to find out." Naruto answers.
"Well no time like the present 'Amaterasu'" Naruko shouts as the tree in front of her is completely covered in black flames.
"Use way less chakra that was already like a fifth of what I normally use.
"Blaze release: Black sword" she says again and the flames form into a dense black sword.
"Never could make it that dence before and it was way easier too, I love this." Naruko shouts in excitement.
"Now try and see if you can use kamui, start with trying to absorb a rock, focus on trying to make a tear in space time" Naruto says.
Naruko takes a breath and focuses on a rock and there is a swirl around a rock and it vanishes along with some of the ground around it.
"Good job that was better than my first try, now let's see what I can do" Naruto says.
He focuses on making himself intangible and says "Alright grandpa try and punch me"
Jiraiya hesitates for a second before he punches at his grandson, just for his hand to pass right through him.
"That feels so weird" he says, shivering as he pulls his hand out.
He then focuses on a rock like his sister did and it vanishes in a tiny swirl not even taking the ground with it.
"You were right sis it's way easier." he says.
"Alright now for Amaterasu, think about taking flames and vibrating them a high frequency" she says
As he focuses on vibrating flames the poor tree from earlier once again catches on fire
"Good work" she says.
"Now for the big guns, susanoo" He replies
"Same time?" she asks.
"Yep, grandma, grandpa you might want to stand back, way back."
Jiraiya and Tsunade jump back a good 100ft from them.
"3" he says
"2" she says
"1" they say together
"SUSANOO" they shout in unison.
Gigantic 50ft red and orange warriors manifest around them wearing battle armor both are holding a katana in their right hands.
"Lets see how far we can go," Naruto says.
They push more chakra into the technique and the warriors grow legs and the armor evolves with armor plates expanding on the torso and shoulders the warriors now standing nearly 100ft tall.
They push even farther and the warriors grow farther; they appear in a prism near the forehead as the warriors grow farther when they hit 250ft tall they begin to grow wings.
Naruto now stands in his Orange perfect susanoo while Naruko stands in her red one.
Both ethereal warriors fistbump then begin to dipell leaving the twins standing back in their clearing with massive smirks on their faces, but out of breath it took a lot out of them and they don't have good control yet.
