AN1: I guess its implicit as I have stated that Kairi, Xion, and Namine are part of Naruto's harem but this also includes another case of 'girl wanting to be with Naruto who happened to share the same blood as him'. After this chapter I will be working on other stories but I hope the ending does give you an idea what to expect! Hope you enjoy!
Chapter 7 Hidden Truths
"It can't be! It was shattered during the Keyblade War!" Xigbar shouted unexpected angry and confused.
'Odd quite the reaction from someone who has second hand knowledge of the X-blade. Most curious. He acts like he was there during the War.' Luxord thought as he analyzed Xigbar reaction with a small smile.
"Believe me. This thing is the true X-blade. Not some copy created from the clash of an equal light." Kurama explained as Ventus and Vanitas notably winced in memory. Aqua put a hand on Ventus shoulder while Vanitas growled underneath his mask.
"Or a copy created from the clash of 7 Lights and 13 Darkness." Kurama mocked as Master Xehanort frowned but his eyes were focused on the X-blade which continued to hum with power and light.
"How? How can you or I suppose Naruto have it? It was gone since the keyblade war!" Mickey asked as he resisted the urge to bow to the power of the X-blade.
"Heh. I suppose you all know the legend of the X-Blade? How it was the counterpart of the True Kingdom Hearts and how it was shattered as the result of the Keyblade War?" Kurama asked rhetorically.
"Yes. It shattered to become the 13 original Darkness and 7 Pure Lights which formed the Princess of Heart hearts." Master Xehanort added with a hint of impatience as he clenched his fist.
Kurama spotted out the corner of his eyes Kairi flinch at the Princess of Heart title and out the corner of his eyes Vanitas shifted slightly at the Original 13 comment.
"Yes, but there is a part of story no one not even the people who was there knew. The X-Blade heart did not vanish but rather it fled that day." Kurama revealed to the shock of everyone.
"The X-Blade's heart?!" Sora shouted along with Roxas.
"Wow. I am surprised you people of all people are finding it hard to think of the X-Blade having a heart. Didn't you tell that Riku over there that there are hearts all around us even in data?" Kurama mocked as he gestured to Dark Riku who scowled.
"That is not possible. The X-Blade is merely the Key to Kingdom hearts and a weapon to be used by those who are superior enough to wield it." Terra-Nort claimed denying the idea of the X-Blade having its own heart.
Kurama looked amused as he released the X-blade which hovered in the air. The X-Blade seemed to become brighter as pure blue light hummed from its glowing frame. Terra-Nort all the sudden screamed in pain. Everyone turned to the possessed form of Xehanort taking over Terra's body.
"What is this?!" Terra-Nort screamed with notable terror in his voice.
Terra-Nort was shining in the same blue light but it appeared that his body was starting to disintegrate right in front of his eyes. Terra-Nort tried to swat away the light but it continued to glow brighter. Terra appeared to start to fade away as the light consumed him.
"Terra!" Ventus screamed in horror even as he tried to cover his eyes from the intense light.
Strelitzia had Marluxia and Larxene cover her with their bodies. Mickey summoned his keyblade in front of him as Donald and Goofy stood behind him. Riku stood in front of Sora and Kairi while Roxas and Lea were in front of Xion and Namine.
"This is just like when the Light of Kingdom Hearts consumed Ansem on our first journey!" Donald shouted as Goody nodded.
"Yeah! Is it the same light? Or is this power the power of the X-Blade itself?" Goofy asked.
The seekers of Darkness backed away from Terra-Nort as they could feel their very being start to fade away the closer they got towards the light. Ansem the Seeker of Darkness and Xenmas looked uncertain of their original fading away before their eyes. Master Xehanort had an impassive look at his counterpart presume demise. Dark Riku still had a smirk on his face even as Terra-Nort screamed in pain.
"Please stop! You will kill Terra too!" Aqua begged as she knew her friend would be gone if his body was disintegrated.
Kurama looked uncaring before sighing.
"That's enough." Kurama stated calmly as he grabbed the X-blade as if it did not burn him.
The X-blade seemed to be annoyed as a light appeared around Kurama who seemed unaffected.
"You know Naruto wants to save the Guardians of Light. If you destroy that possessed body Naruto will not be able to save that boy Terra. Are you truly willing to destroy what Naruto wants to save?" Kurama asked drily as he did not release the X-blade despite the light seemingly trying to burn him now.
The X-blade almost seemed to 'pout' as its light flickered on and off before the light dimmed along with the light burning Terra-Nort. Terra-Nort dropped his knees as he panted from his traumatic experience.
"That thing in your arm…. It's a monster not a weapon." Terra-Nort declared hatefully as Kurama whistled.
"Hypocrite. Till 2 minutes ago your goal from the 13 Seekers of Darkness was to reforge this X-Blade and use it to open up Kingdom Hearts. Now it has been shown to a threat to you, you call it a monster and something that should not exist." Kurama pointed out with a toothy grin but his eyes showed annoyance towards the possessed Terra.
Xigbar shoved Terra-Nort to the side much to his surprise as he smacked his hands against the barrier.
"How is it possible? The X-Blade very essence became the Original 13 Darkness and 7 Pure Lights. There is no way that boy had it inside of him. The 13 Darkness and 7 Pure Lights did not reunite into the X-Blade!" Xigbar demanded revealing the method to create the original X-blade to the Guardians of Light.
Kurama gave him a knowing look as he spun the X-Blade in his hand.
"The X-Blade already knew of its destruction but it could not stop it. Instead it hid its heart and fled while the Keyblade Wielders fought over its power. You underestimate the power of the X-Blade. It can foresee the future and past even if it has no wielder to interpret that power." Kurama revealed as he looked at the X-Blade with distaste and respect.
"I don't care about any of that. All I care about is getting my brother back! If that X-Blade or whatever you call it can help then I will gladly beg on my knees for its help!" Kairi declared as she stared at Kurama with pure determination.
Kurama stared at Kairi for a moment before a hint of a smile appeared on his face.
"You lack his power or conviction but there is one thing you and Naruto have that is similar. Deep down I suppose you will do anything to help the suffering. Perhaps it's a trait you inherited from your mother and father after all." Kurama admitted looking away.
"Did you just give me a compliment? I thought you didn't like me?" Kairi asked but Kurama didn't answer.
"Hey. Stop acting like you can't talk. Part of your essence is inside that girl. She is a Pure Light so it should be your responsibility to explain." Kurama commented.
"….." The X-blade appeared to be silent as everyone turned to Kurama looking unimpressed.
"Um…. I know the X-Blade Is moving on its own but it can't talk right?" Roxas asked cautiously as Xion and Lea had similar disbelieving looks.
"Can your Keyblade talk Sora?" Goofy asked as Sora shook his head.
"Nah. I can sometimes tell it wants me to do something but it has never talked to me like you guys." Sora confirmed as he summoned Kingdom Key to show his point.
Kurama rolled his eyes and let go of the X-Blade which hovered and floated around Kurama.
"The X-Blade is different is different then Keyblades. A Keyblade no matter if its unique to a certain person like you wielders of Light or passed on like the Old Man's Xehanort's is tied to a user's heart. The X-Blade has a will of its own along with a heart and has chosen the actions it has taken." Kurama remarked as he pointed at Master Xehanort who was staring at the X-Blade with undisguised desire and want.
"….. I have to follow certain guidelines as the counterpart to Kingdom Hearts. I cannot intervene too much in the destinies of others." The X-Blade finally explained as it hummed while it 'talked'. The voice of the X-blade appeared to be a mature woman who sounded tired and sad at the same time.
"The X-Blade talked!" Sora exclaimed looked surprised along with the rest of the Guardians of Light.
The X-Blade turned around so it was facing Sora.
"Yes young Keyblade wielder. I have always had this ability but before Naruto realized his destiny I have never needed to talk. I needed to wait for his arrival so I hid myself and watched." The X-Blade explained patiently.
Master Xehanort made his presence known as he stepped forward and put his hand out as if trying to summon the X-Blade. Nothing happened but the X-Blade did turn around to face him.
"Enough. I have searched for you and tried to create a version of you for many years and yet you are complete and all powerful." Master Xehanort stated as he gripped his hand in anger.
"Your point being? Naruto is the one I foresaw and the one I have chosen not you." The X-Blade stated coolly as Kurama snickered.
"Come to me and we can restore balance to the worlds. There will not need be a war or any more suffering if you simply come over here." Master Xehanort claimed as he looked expectantly at the X-Blade.
"Don't listen to him! He wants to fill all the worlds with darkness and send them to ruin!" Aqua exclaimed as Terra-Nort scoffed.
"Such simple thoughts especially for a Keyblade Master. Did your Master really teach you anything of wild or did he simply teach you such simple viewpoints like 'light is good and darkness is bad!'?" Terra-Nort mocked smirking when Ventus and Aqua glared at him.
"Shut up! Its because of you that Master Eraquas is gone!" Aqua yelled as Terra-Nort looked amused.
"True. I Xehanort struck the final blow on Eraquas." Terra-Nort admitted freely.
'Idiot. What point is it to announce it to everyone.' Vanitas thought drily.
"However, I only ended Eraquas after Terra weakened him to the point of near death beforehand. So really your hatred is towards this vessel and nothing else." Terra-Nort commented as he pointed to himself with a smirk.
Aqua looked ready to summon her keyblade but Ventus with a rare show of seriousness held her back. The look on Ven's face made Aqua flinch for a second. She was used to her friend/younger brother figure smiling or pouting but this expression was very different.
'Ven look like he wants to make them pay but his eyes look like someone who has faced a lot of darkness and prevailed. What is Ven thinking?' Aqua thought as Ventus stepped forward.
"I am getting Terra back no matter what. So until then keep your mouth shut." Ventus hissed as his glare made Vanitas flinch behind his mask.
'This feeling. Its almost like he has resolved to do whatever it takes even if it costs him everything he has. Why do I feel fear?' Vanitas thought. AN2:
"Are you done? Resetting the Worlds won't bring the peace you seek Keyblade Master Xehanort." The X-Blade stated impatiently as Master Xehanort narrowed his eyes.
'How does the X-Blade know of my true intentions. Does it truly have the ability to see all even things hidden in lies?' Master Xehanort thought.
"What are you talking about?" Riku asked confused as it did not seem like what they were told about Xehanort.
"He does not want to drown the worlds in darkness. Rather Darkness is simply a tool he has justified using in his attempt to destroy Darkness once and for all." The X-Blade commented with notable amusement.
"If he uses a version of me and Kingdom Hearts, he can reset the worlds and erase the existing darkness. The realm of Darkness will cease to exist and people will no longer have darkness in their hearts." The X-Blade explained much to the shock of the Guardians of Light. AN3:
"That's impossible. That can't be true." Mickey mumbled in disbelief. Aqua and Ventus looked equally in denial while Master Xehanort looked stoic.
"If your goal was to erase darkness then why did you and your other selves cause so much suffering and pain for everyone?" Sora demanded as Kairi kept her focus on Kurama who was in control of her brother.
Kurama looked amused but clenched his fist as if remembering something unpleasant.
'Damn Uchiha and Kaguya. Its just like that jutsu.' Kurama thought as an imagine of the Infinite Tsukoyomi and Divine: Deep Forest Emergence appeared in his mind. An imagine of a smirking Kaguya with her Rinne-Sharingan and Byakugan along with massive trees enveloping the Ninja World appeared in his mind.
"….. So, you can tell huh. You must truly have the ability to see what lies in our hearts after all." Master Xehanort remarked after a notable pause.
"So its true? You altered all of our destinies to destroy the Darkness we have been fighting all this time?" Mickey demanded in anger as Young Xehanort smirked.
"Little King. As long as humans and beings have free will they will create Darkness no matter how much of it you banish away. Darkness exists in every heart and Darkness is the hearts true essence." Young Xehanort claimed as Xenmas and Ansem solemnly stepped forward.
"For Darkness to no longer exist you need a power far greater then Light. Light creates darkness after all." Ansem remarked with his eyes somewhat sad although he covered it quickly.
"Kingdom Hearts is the only power that can affect all beings in every world. The X-Blade is needed to summon and control its power. No sacrifice can be considered too much if it helps everyone in all worlds." Xenmas noted as he glanced at the glowing X-blade with desire.
"What would happen if Xehanort used Kingdom Hearts to purge the worlds of darkness?" Xion asked the X-Blade.
"He would be able to force Darkness to cease to exist however to prevent more darkness from forming he would trap all people under his control. They would live peaceful content lives and forget about everyone they knew before. They would no longer remember a life or world before they were simply content." The X-Blade revealed to the Guardians of Light horror. AN4:
Strelitzia turned to Marluxia and Larxene who looked down with shame.
"You knew this was his goal and you still aided him?" Strelitzia accused her brother and her sister figure.
"…. I didn't remember about the past but I thought this was the right away to get rid of conflict." Marluxia admitted in sorrow as his memories of Strelitzia were lost as a result of time travelling to the current era.
"I just went with what Marluxia did. I didn't really care what the end result was." Larxene admitted looking away from Strelitzia frown.
"Think of a dream you could never wake up and never realize you were in. Everyone would be happy but they would never be able to choose anything else but the happiness given to them." Kurama scoffed with notable distaste as Naruto's face scrunched up in disgust.
Master Xehanort frowned as he turned to face Kurama with a look of disappointment.
"Beast that controls the brother of the Princess of Heart. What more could you ask for everyone eternal happiness at the cost of free will?" Master Xehanort asked.
Kurama glared at him as his hand started to strain with anger. Kairi saw this and frowned before she turned her glare at the old Keyblade Master.
"Shut up! Don't call him that!" Kairi snapped much to everyone shock while Xion and Namine shared content smiles.
"Kairi?" Aqua asked shocked at the outburst.
"I don't care if you are some big tailed beast inside my brother. You are the reason he is alive now so I can accept you as a person." Kairi declared as Riku and Sora also nodded in agreement.
"Hmm… I suppose for his twin you aren't bad." Kurama declared closing his eyes but had a hint of a smile on his face.
"Now X-Blade. I need you to open a portal to the Elemental Nations so I can drain the chakra of the people there." Kurama reminded the X-blade looking down at it.
"Drain? Speaking of things Naruto of all people would not approve of." The X-Blade reproached Kurama who scoffed.
"Fine. Just open a link and I will ask for a donation of chakra from everyone there. A portion of everyone will make up the vast amount he has alone." Kurama agreed rolling his eyes.
The X-Blade flickered before a hum could be heard.
"That is one option but there is another option. One I think will be more enjoyable than taking thousands of humans worth of chakra." The X-Blade mused.
Kurama eyes widened before he growled at the X-Blade.
"You better not be thinking of bringing HER!" Kurama hissed as the group could almost feel the X-Blade smirk smugly.
"Who are they talking about?" Sora asked Riku who shrugged.
"No idea but if she can help save Naruto's brother, she can't be bad right?" Riku suggested as Sora nodded slowly.
'You won't be saying that if she gets summoned. Hell I think it will take all your will power not to want to die of shame from making a fool of yourself!' Kurama silently fought.
Kurama attempted to unsummon the X-Blade but it remained firmly in his hand before it started to glow and its blue aura got brighter and brighter. A massive beam of Light shot from the X-Blade into the pace in front of Kurama and a door seemed to appear. The Door was bright yellow and footsteps could be heard as if someone was going into it.
"So bright! I can't see anything!" Lea complained as he covered his hand over his eyes. Luckily everyone else besides Kurama was having the same issue. Kurama was scowling as if annoyed at who was coming out the door.
There was a flash of light that nearly blinded everyone before it started to dim down. In the light stood a young woman looking roughly Aqua's age. The woman was a few inches shorter than Naruto now standing the same height as Aqua. The woman had long blonde hair that seemed to shine in the sunlight that was in two long ponytails that reached her hips and tied up with blue scrunchies. She notably had three whiskers on her cheeks which framed her face to give her an even more cute look to her stunning good looks. She had the same skin tone and colour as Naruto did.
The woman had her eyes closed but her smile showed she was listening to what everyone was saying. She wore a dark red of red lipstick that contrasted with her blonde hair but only enhanced her good looks. She had a very mature busty figured with an hourglass figure. She has a tiny waist that contrasted her wide hips showing how hourglass she had. Her long legs were visible and seemed to never end.
The woman wore what she would proudly call a 'modified ninja outfit'. Her top was a orange crop top that had a zipper from the top to bottom and the top itself was rather small. It was sleeveless allowing her long arms to be visible and it only went down to her waist. For her pants she only wore small shorts that went down to her lower hips and there was a patch of skin shown in between her crop top and her black shorts.
This revealed her well toned flat stomach and hips. The crop top barely covered her large breasts which seemed big enough to pop open her crop top at any moment. Her black shorts only went to her lower thighs showing off her long legs that seemed to go on forever till they ended in black ninja heels that revealed her toe nails.
The woman wore light blue finger and toe nails that glittered along with her red lipstick. If you were standing behind her you could see that along with a very large breasts the woman appeared to have a very spankable bum as well especially in her tight black shorts. AN5:
"Hmm. I never thought the X-Blade would summon me to such a dreary place." The Blonde woman commented with a musical voice that seemed to hum in amusement.
The mystery woman stretched her arms into the air humming as she stretched her tired muscles. This had the side effects of making her very large chest bounce inside of her cop top as if defying gravity itself with their size and bounce.
Every woman jaw dropped while every man had various degrees of blushing at the woman who blinked several times before she opened them revealing sky blue eyes that was the same shade as Naruto's.
"Hello friends and I suppose enemies of Naruto. My name is Natsumi Uzumaki." Natsumi stated cheerfully with a wink and wave.
Riku and Sora both blushed up a storm at the attractive woman while Donald and Goofy looked away with tiny blushes. Mickey who only had eyes on Minnie was wide eyed at the woman as she was waving. Lea had his jaw drop to the ground with a notable blush at the woman. Xion glared at Roxas who was gawking before she slammed her fist into his stomach before doing the same to Lea.
Namine and Kairi kept their eyes at Natsumi breasts with envy as they continued to bounce slightly even as she was just standing there and waving.
"How can she be wearing such revealing clothing! Its scandalous!" Aqua mumbled ignoring or unaware that most men that met her thought her outfit was rather sexual.
'Okay seriously how can she move at all! They are so big and round!' Aqua thought in annoyance.
Aqua smacked Ventus on the head roughly but then ruffled his head when Ventus stopped gawking and rubbed his head in pain.
Marluxia and Larxene covered Strelitzia face as if to keep her innocence intact.
'Wow these keyblade users are kinda prudes Dattebane! I guess most of them are still technically teens but wow its like they have never seen a pretty girl in their lives.' Natsumi thought in amusement before she glanced at the Seekers of Darkness inside Naruto's Four Crimson Ray Formation barrier.
Terra-Nort was still growling at the X-Blade in Kurama's hand, Young Xehanort merely raised an eyebrow at the new development, Ansem and Xenmas looked rather uninterested. Vanitas looked bored but Natsumi could sense his unease at her presence as if threatened by her existence.
Xigbar looked uncertain at Natsumi almost as he was not expecting her appearance but tried to cover it up with a smirk. Luxord whistled looked rather impressed as he looked like he was considering his options. Saix did not look at Natsumi but did look at the corner of his eyes at Lea, Roxas and Xion with notable envy and sadness which he hid behind his emotionless mask. Dark Riku kept glaring and growling as he was looking at Riku with barely disguised hatred.
"Its rude to stare you know. Aunty Mei might enjoy the lust of men but I am not a huge fan of it." Natsumi chirped with an adorable pout as she put her hand of her hip and cocked the other one to the side in notable annoyance. This had the side effect of making the young woman look even more sexual. AN6:
Kairi was the first to recover as she put a hand over her own petite but growing chest in surprise.
"Wait…. Uzumaki? Does that mean you are…?" Kairi gasped as her eyes widened. She zeroed on the whisker markings that were identical to the ones on her brother.
"Congratulations. You can hear correctly. Yup. I am a 'Naruto' from a completely different world and timeline where my parents had a single girl not twins before their death." Natsumi informed them cheerfully.
"Right? Kurama?" Natsumi chirped as she gave a huge grin at Kurama who growled at her.
"Grr. You irritate me as you have another 'me' inside of you and you are certainly not Naruto to me." Kurama replied in annoyance although he did notably inch away in discomfort when Natsumi put her arms out and tried to hug him.
"Pooey. You are grumpy still. Maybe it's me. As Kurama inside of me is worried about Naruto over there but you seem to dislike me." Natsumi noted with a pout but she ruined her sad expression with a giggle.
Kairi along with Xion and Namine gasped as Natsumi turned back to them with a calculating expression.
"Hmm. I need to take a better look at you three later. First Aqua." Natsumi mumbled as she out her chin in her fingers with a look of deep thought.
"Excuse me? What are you asking for?" Aqua asked politely blinking when Natsumi leapt forward and landed directly in front of her.
Natsumi seemed to look carefully at every inch of her humming as she seemed to take in every feature of Aqua. Aqua was uncomfortable when Natsumi walked behind her as she could almost feel Natsumi stare on her shorts and her mostly exposed back.
"You will do." Natsumi mumbled as she walked past the confused Aqua ignoring everyone else.
'Yeah, Aqua is definitely his type. Tall and beautiful with nice well-developed features.' Natsumi noted to herself in approval.
Natsumi ignored everyone who was calling to her as she leapt forward in between Kairi, Namine and Xion looking them over. They had to resist the urge to try to cover their own petite chests when Natsumi eyes glanced over their tops. They almost felt a sense of inferiority especially compared to Natsumi very large chest and her stomach showing without Natsumi seemingly feeling any shame.
Natsumi eyes peeked at the edge of their short skirts silently noting that Kairi and Xion boots fit their legs rather well. She also silently enjoyed Namine rather cute blue sandals.
"You three pass too. However, I will say you might want to wait a few years if you want to catch up." Natsumi mused with a nod of approval.
"Okay first of all! Pass what?!" Xion demanded with a slight glare but it was mostly envy.
Natsumi tilted her head as if Xion asked what two plus two was.
"For Naruto's mates. I approve the four of to become Naruto's mates in the future." Natsumi stated cheerfully with a wink and peace sign.
"…" The Entire Keyblade graveyard was silent to the point a cricket could have been heard if one was chirping.
"WHAT?!" Kairi, Xion, Namine and Aqua screamed at the same time with their faces comically large and red with embarrassment.
"Huh? Is 'mate' not used in the realm of light? Perhaps girlfriend? Lover? Future wife? Mother of his children? Are those terms clearer?" Natsumi added cheerfully as Kurama face palmed.
"I am glad I wasn't sealed in another female Uzumaki. Only they could be so bashful and upfront about mating. Such confusing humans." Kurama sighed as he sent Natsumi a dry look with his expression not changing when she waved to him.
All the Guardians of Light had various degrees of blushes with none so much as Kairi, Namine and Xion.
"Hmm. That boy has certainly good luck and odds. Even his counterpart notes his luck with women." Luxord noted with amusement and a chuckle as he looked down at his hand of 5 cards.
"Is that woman for real?" Young Xehanort asked unamused.
"I cannot detect a lie in her expression." Xenmas noted stoically.
"So, she must feel that way sincerely." Ansem added with his arms crossed.
"Idiots." Vanitas simple answer showed his annoyance.
"As if. His and her worlds must be full of degenerates to suggest such things." Xigbar suggested with a laugh.
"…" Saix didn't say anything but he did look at Xion with a hint of concern which was overshadowed by his expressionless face.
"Ha! She might be a secret Guardian of Light! She is a weakling like them!" Dark Riku claimed with his superior smirk.
"Does this matter?" Terra-Nort asked flatly.
Master Xehanort was not even paying attention with all his attention on the X-Blade which was still in Kurama's hand.
"Mate?!" Strelitzia squeaked as Marluxia and Larxene had dropped their hands in shock. She had her face a deep red but she also had her eyes focused on Natsumi large chest.
"As long as he doesn't go after my sister, I see no problem with it." Marluxia claimed but Strelitzia was too embarrassed to correct her brother.
"I don't know what to say. That ninja girl is so random I can't even." Larxene stated with a sigh. She put dramatic hand over her forehead.
"They are his sisters!" Riku screamed indignant on behalf of his younger sister figure.
"Huh? And?" Natsumi asked as if he said something rather odd.
"How can you be like 'huh'? Its so weird and wrong!" Sora stated.
Natsumi and Kurama shared a rather dry expression. Kairi noted despite Kurama face looking different as a result of controlling Naruto's body Kurama and Natsumi still had the same face shape.
"If there was a clue you haven't been to mine or Naruto's world its that ignorant stance on relationships." Natsumi remarked with her hands on her hips and a sigh.
"Hey quit talking to us like that!" Donald snapped as Goofy attempted to apologize for his partner behaviour.
"Look. I will be frank almost everyone who has a bloodline or last name lineage has some sort of ancestry where there is some marriages between cousins or closer." Natsumi remarked as everyone looked dumbfounded at her.
"Kurama told you about the Sage of Six Paths right? He was the father of Asura who was the ancestor of the Senju Clan and Uzumaki clan along with the father of Indra who was the ancestor of Uchiha and Kaguya clan." Natsumi explained as the X-Blade showed an illusion to highlight her point. AN7:
"Anyways Old Man Six Paths was alive a thousand years ago. His blood that makes up the 4 clans would have diluted to nothing by now if everyone married and had kids outside the clans. Most people born into the clans have ancestors who had children from within the clan so the blood wouldn't vanish." Natsumi stated calmly. AN8:
"Wait! You said Uzumaki clan! You mean?" Riku shouted in realization as everyone turned to Kairi who had turned red when she realized where there was going.
"Yup. Father was an orphan called Minato Namikaze but mother was Kushina Uzumaki. Her parents were first cousins and their red hair passed to her." Natsumi confirmed with a nod. AN9:
Kairi was gaping at the reveal her mother was born from cousins while Namine and Xion blushed at the thought that it would be considered 'okay' to be in a relationship with their 'brother'.
Aqua looked annoyed and outraged as she pointed a finger at an amused Natsumi.
"Okay look. I won't judge the customs of your or Naruto's worlds. Every world is different." Aqua stated as she took several deep breaths to calm herself.
"However! Why on earth would you suggest all 4 of us to become Naruto's 'mate'! He would be in a relationship with multiple girls!" Aqua snapped indignant as Natsumi giggled.
"Wow. Prude. Naruto is a male Uzumaki. He has the life force of the Uzumaki clan flowing through his blood along with the stamina of being a Jinchuuiki. Let's just say that having multiple girls is not something that would bother him." Natsumi stated with a wink and slight blush.
This admission made everyone blush when they realized what Natsumi was referring to his stamina as.
"Please. Don't act innocent. You yourself want Naruto to bed you. Its so obvious its sad. Its only the close-minded natures that prevented them from seeing it the instant you came here." Kurama whispered with a grin showing his large teeth.
"Never claimed I don't want Naruto to be my soul mate. He is literally the perfect person for me. With that X-Blade of his he can visit my world. We will find a way together." Natsumi whispered back as she eyed Kairi red face.
"Got to say it does annoy me abit that all Naruto can think about is Kairi when he has a smoking hot blonde version of himself wanting to jump him." Natsumi whispered at Kurama who rolled his eyes.
"She is his family. The last part of his parents that still lives on. Of course, that is all Naruto is worried about at the moment." Kurama stated out loud as everyone looked over at him.
"What are you guys whispering about?" Lea asked looking at Kurama instead of Natsumi as he could feel Xion glare drilling into his face.
"The reason why Naruto chose to face more pain and suffering by leaving his world. He could have lived in ignorance but chose to face a new destiny when he learned he had a sister. Now three I suppose. All because of you Kairi Uzumaki." Natsumi stated seriously with a hint of jealousy as she stared at Kairi blue eyes that were the same as her own. AN10:
Natsumi raised a hand up before anyone could say anything in response.
"To be clear though. You are not my sister. I might be a 'Naruto' from another world but my parents never had another child besides me. So don't expect me to coddle you like Naruto does." Natsumi explained coolly with her eyes narrowed.
This made the Guardians of Light gulp with Kairi, Namine and Xion looking uncertain at this busty blonde.
"However. I don't mind if we become friends!" Natsumi chirped with her bubbly personality back in the front.
'Honestly, I think my version of mom and Dad could not actually object bedding another version of me. They would want me happy and he would make me happy even if I am not the only one in his life.' Natsumi mused resisting blushing at the thought of her and Naruto sharing a bed.
"I am going to ignore all this weirdness…." Namine stated awkwardly trying to not look at her brother counterpart very large chest with Natsumi smirk not helping.
"Can you really save him?" Namine pleaded as everyone looked expectantly at Natsumi.
"Yup. I am the only one who has close to Naruto's actual levels of chakra. So if I transfer some of mine it will restart Naruto's damaged chakra and help him wake up." Natsumi promised with a determined look.
All the sudden they heard laughter as they turned around to see Dark Riku laughing to the pint where he was putting a hand on his stomach to calm himself.
"Really? You would give up your life force to heal that loser?" Dark Riku mocked with a dark grin going along with his yellow eyes making him seem like a true villain.
"Why you!" Riku growled disgusted at the being he thought was his past self possessed by Ansem the Seeker of Darkness.
"Why the glares? He chose to sacrifice himself for that pathetic girl over there and now you want to bring out all the stops to save him?" Dark Riku mocked pointing at Strelitzia who looked down.
Marluxia and Larxene looked ready to rip Dark Riku to shreds and even the rest of the guardians of Light looked disgusted at this version of 'Riku'.
All the sudden they felt an intense pressure that seemed to bring everyone to almost their knees. Everyone turned around to see a blue aura around Natsumi as her pretty face was now cold with a dark smile.
"Kurama. I guess before I revive Naruto, I will thin out their ranks abit. Do Naruto a favour before he wakes up." Natsumi suggested as lightning surged from her hand for a moment.
"Tch. I guess that brat does piss me off to. Do what you will." Kurama replied as the X-Blade shone for a moment.
Dark Riku was surrounded by light before he vanished and reappeared in front of Natsumi several feet much to the Guardians of Light surprise.
"Wow thanks!" Dark Riku stated muckily with a mocking smile and bow.
"When I make you protectors of light submit, I will get my prize." Dark Riku announced as he pointed to the X-Blade in Kurama's hand.
Kurama scoffed as if Dark Riku stated something stupid.
"I will enjoy it when your face is on the ground begging for mercy. Anyone who mocks my Naruto is going to pay." Natsumi announced as she took a step forward.
Dark Riku summoned the power of darkness and had his Soul Eater in hand. Riku winced when he saw that blade subconsciously remembering how much bad he did when he used that blade freely.
'My Naruto'? Namine thought as she was in the back not having combat abilities.
Another battle of Light and Darkness was about to begin but Natsumi would show she was not light in the sense she had more flexible morals.
AN2: KH3 RREMIND and KH union cross reveal that Vanitas is the physical form of the Darkness that was inside of Ventus as they travelled to BBS era. In Dark Road its highly implied Vanitas is well aware of his nature of being one of the "True Darkness's". Here his memories are jumbled so as a "Darkness" he is feeling the same fear he had when he was formless and Ventus sealed him inside of himself.
AN3: Probably a stretch. We are only told that Master Xehanort goal was to destroy darkness and that resetting the worlds with Kingdom Hearts would apparently do that. I am filling in the 'what and how'.
AN4: Basically in this version Master Xehanort would force all conflict to end by controlling people to live happy lives and not be able to be in conflict with each other. It's a huge scale kinda like how Endgame Thanos wanted to created a new universe but this time nobody would oppose him as they would not have known about the past and what was needed to be done to create happiness.
AN5: This is the same description I used in Six Paths Jinchuuriki in chapter 54 but this is not 'sexy jutsu' Natsumi but rather a different Natsumi who lived in an alternate world of the Elemental Nations. Like Naruto's it also exists outside the realms of Light and Darkness and the in Between.
AN6: This is not Naruto's sexy jutsu. This Natsumi has a very distinct personality. Also Mei is called 'Aunty' as Natsumi is in the presence of the X-Blade which is highly implied to be the source of the everyone speaking the 'same language'.
AN7: The Kaguya Clan thing is kinda my idea but the data book does say they are descended from Kaguya and she only had two sons before she was sealed away. So more then likely one of Indra's descendants founded the Kaguya Clan through latent genes inherited from Kaguya. I know its possible Hamura could have been the ancestor instead but I personally think its more likely he was just the ancestor of the Hyuga Clan and the Ōtsutsuki Clan of the Moon.
AN8: Again just my thoughts but I do feel that its one of those hidden things in the Naruto lore. You got to admit the Uchiha an Hyuga clans do have similar looking clan members.
AN9: Again just my opinion but it does seem like Kushina was born in Land of Whirlpools so more then likely her parents were inside the clan if you know what I mean.
AN10: The keyblade Graveyard is NOT the first world Naruto had to go to after he left The Elemental Nations (nor is the Elemental Nations Natsumi comes from). He had to travel to many worlds before this moment using the X-Blade power.
