AN1: This is an AU so the events of the Keyblade Graveyard and even some of the canon lore will be vastly different. Naruto's homeworld is 'outside the realms of Light, Darkness and the in between'. It is very hard to actually enter (so even Luxu and Master of Masters do not know of it).
Yeah I know "Please update other stories" but I get bored easily so I need to put stuff I want to update. This chapter is just a prologue essentially. Not sure if I will even continue it as it seemed Kingdom Hearts in general has a lackluster fan base on fanfic.
READING THE FOX SCROLL was taken down on June 24/2021(Thursday). I added a link to its new home on my wattpadd. I used the original docs (hence the Ans) but the format is a bit different due to the different site.
Btw this is not supposed to be taken as a serious fic. So if I add something like incest I am not condoning it for a serious fic.
Chapter 1 The brother
It was finally time. The Second Keyblade War was about to start in the land where the first one ended with most Keyblade Wielders dead at the hands of not darkness but their fellow Keyblade Wielders.
Master Xehanort had declared war on the Light with him and his 12 other 'selves' as the 13 seekers of darkness against the 7 Guardians of Light. Despite the attempt to stop the war by not fighting it the War was inevitable as Master Xehanort threatened to go after the 7 Pure Lights or know as the New Seven Hearts as an alternative method to get his prize-the X-Blade.
The 7 Guardians of Light were made of 7 Keyblade Wielders who aligned with the light- Sora, Riku, Kairi, Aqua, Ventus, Mickey and Lea. They also aided with Sora's party members Donald and Goofy who despite not having keyblades were with Sora his entire journey.
The Guardians of Light landed in the keyblade graveyard as they looked rather solemun at the place. None so much as Aqua and Ventus and to a lesser degree Mickey.
"Never thought we would have to come back to this place. Especially for Xehanort's plans once again." Ventus said with a frown before Aqua gently grabbed his shoulder for comfort.
"We will win this fight and get Terra back for sure." Aqua told Ventus with determination as Ven looked up and nodded.
"Guys lets go. This will be the final battle for all our friends and we won't lose." Sora declared as everyone nodded at Sora as they started to run forward.
They kept for awhile until Lea decided to add in his two cents.
"Hey. Isn't this kinda weird?" Lea asked as everyone stopped to turn the red-haired tall man.
"What is Axel?" Kairi asked the former Nobody by his Nobody name.
"I mean this is the Final Boss, right? And this is his strong hold?" Lea asked as Aqua raised an eyebrow.
"Yes." Aqua replied simply wanting him to get to the point. Aqua was a relatively tall blue haired woman with a slender figure and blue eyes. Due to being inside the Realm of Darkness for over 11 years she retained her appearance of an 18-year woman despite being technically in her early 30s.
"Isn't it odd this place is not crawling with Heartless and Nobodies?" Lea asked as everyone looked at him with shock.
"I mean even in the original Organization 13 world we had hoards of Nobodies and Heartless basically everywhere but we haven't seen anybody besides us." Lea pointed out as Sora and Riku nodded remembering how infiltrating Xemnas stronghold was not possible in a stealthy manner.
"It is odd." Mickey admitted as he scratched his head while Donald and Goofy looked at each other with nervous expression.
"They must be hiding their strength or luring us in a trap." Riku suggested as Kairi bit her lip in nervousness.
Sora however had a determined look as he looked at his allies.
"It doesn't matter. As long as we do this together there is no reason to be afraid!" Sora announced as everyone expression relaxed while Donald and Goofy sent silly looks at each other.
'Good old Sora. This pep talks is so his thing.' Donald thought with a grin as they all nodded in determination before they started to run again.
Further in with the True Organization 13
"Talk about boring!" Larxene complained as she crossed her arms in front of black coat. Larxene was a rather slender woman with flight blonde hair and green eyes. She notable had a hourglass figure notable even in her black coat.
"I must agree Old Man. Can't we send some of our army to make it at least a bit interesting for the Guardians of Light?" Xigbar suggested referring to the vast army of Heartless, Nobodies and Unversed. Xigbar notably had only a single eye with a cunning smirk that some people thought he was constantly hiding his true intentions from everyone.
Master Xehanort stayed quiet as he glanced at 'other selves' with a cool expression.
"Perhaps I shall greet them? Maybe they would like to see their old friend…. Is just fine?" Xehanort in the body of Terra mocked. He appeared to be in his prime about 20 with Xehanort's silver hair and yellow eyes as his heart had taken over the body of Terra to regain his youth and strength.
Saix stayed quiet as he glanced to look over at a hooded Xion who did not appear to comprehend anything going around her.
"Feh! Who needs you when I can take care of the Guardians myself?" Vanitas asked confidently being the 'dark half' AN2: of Ventus with a wide evil grin behind his own personal mask.
"You? Please." 'Riku' mocked as his hood was off showing the face of Riku before he matured during the year Sora was asleep. He had a superior look on his face as Vanitas turned around to glare at him.
"Something you want to say?" Vanitas hissed as 'Riku' sent him a mocking smile.
"Oh nothing! It just you ran when it was just little Sora, that failed Master Aqua and your other half back in Fallen Land. I wonder if you will run now that all 7 Lights have gathered?" 'Riku' suggested as Vanitas growled.
"Listen here! I am not some fake like you. I do as I please!" Vanitas growled smiling when 'Riku' calm expression turned dark.
"I am not the fake one! He is!" 'Riku' claimed clenching his fist in anger.
Marluxia and Luxord both stayed quiet with Marluxia expression being more serene as if trying to figure something out.
"Enough!" Master Xehanort declared as everyone flinched and became quiet at the power of the ancient experienced Keyblade Master.
"We shall wait for the Guardians of Light here and then attack them all as a group." Master Xehanort declared as most of the other members gave him looks of disbelief.
"Why should we wait? We have an army and you want us to leave them alone?" 'Ansem Seeker of Darkness' (the Heartless of Terra-Xehanort) asked with a frown.
"It makes no sense to let them come to us at full strength." Xenmas added (who was the Nobody of Terra-Xehanort).
Master Xehanort turned around to face 'his' Npbody and Heartless with a cold expression.
"None of this matters if we do not get All 7 the Guardians to clash with us. If they die before the Final Clash my prize- the X-Blade- will not be forged." Master Xehanort said with authority as the other members reluctantly agreed. AN3:
Back with Sora and the Guardians of Light
After crossing through quite of desert and a cave they finally got to the middle of the world. The actual place of the Keyblade graveyard where countless lifeless Keyblades were buried in the sand to symbolize the lives lost during the First Keyblade War.
Just as the Guardians crossed into the middle they saw dust appear as they stopped.
"They're here." Riku pointed out as everyone hands clenched.
First was Master Xehanort himself as he walked towards them as Mickey glared heatedly at the Ancient Master. Then Ansem Seeker of Darkness appeared as Riku sent a glare in his direction.
Xenmas appeared on the other side of Master Xehanort as Lea frowned at his former superior. Young Xehanort appeared with a mocking grin as both Sora and Riku glared at the younger time traveller version of the Keyblade Master.
'Riku' appeared as Sora gave an uncertain look at his friend while Donald and Goofy stared with determined expressions. Vanitas appeared with his mask on but confident stride as both Aqua and Ventus glared at the embodiment of Darkness.
Larxene and Marluxia appeared as Larxene sent a sneer at Sora which was returned and Marluxia looked coolly at Sora. Lea gave them a mocking bow as they glared at him remembering Axel was part of the reason they were destroyed as Nobodies.
Saix and a hooded figure (who unknown to everyone was Xion) appeared next to him. Lea sent a pleading look at his former friend who had an expressionless face. Kairi sent a frown at the man who had kidnapped her before to use as bait for Sora.
Terra-Xehanort appeared with a cocky smile as Aqua and Ventus glared at him with pure anger in their eyes. Luxord and Xigbar appeared with nobody paying much attention to Luxord. However, Sora and Ventus sent a particular annoyed glared at Xigbar who chuckled at the irony.
They stood in formation before Master Xehanort clenched his hand. The land beneath him and the other Seekers of Darkness grew and expanded so the Darkness now towered over the Light.
"On this Day and on this place history shall repeat itself. A new Keyblade War will occour and when it finishes the X-Blade shall appear to lead me to Kingdom Hearts itself." Master Xehanort declared as the Guardians of Light looked up at him with determination.
"Not going to happen. We will defeat you and save everyone." Sora replied as several darkness like Larxene, 'Riku', Xigbar and Vanitas snorted at Sora's declaration.
"We shall conquer the Light and make it submit." Ansem told them smugly.
"This land is where Light will expire and Darkness will prevail. It was foretold long ago. There is nothing you can do to stop fate from taking its course." Young Xehanort told them with a smile.
Before anyone else could say another word or Master Xehanort could use magic to turn the platform he was standing on into a maze to separate the lights there was a massive beam of light that shot from the sky itself.
The light hit the ground and as everyone closed their eyes and reopened them there was a figure standing in the middle of the Guardians of Light and the Seekers of Darkness. It appeared to be a male who was fairly tall wearing a brown cloak that had a hood covered his face but left his hands showing a somewhat tanned hand.
"A Cloak! Is he with the Organization?" Lea asked as he got on guard along with Sora and Riku.
"Wait! Its not like their cloaks and they seemed surprised." Aqua pointed out as the Seekers of Darkness indeed looked just as confused as their Light counterparts.
"Hey Old Man! Is he one of ours?" Xigbar demanded as the Darkness were complexed at the new arrival and wondering if their leader hid someone they did not know about.
"No. I have never seen this boy before." Master Xehanort acknowledged as everyone attention was on the hooded figure.
"You talk a lot." The Hooded Figure said with a male voice sounding rather annoyed.
"And I don't like when people talk down to me like this." The man said as he walked up to where Master Xehanort had lfited up the ground. He clenched his fist and pulled it back.
Larxene laughed "What is that going to do? Break your hand?" She asked mockingly.
The man hand appeared to glow Golden for a moment as a strange aura and power surrounded the fist. He sent the fist and punched the Earth in a single blow. There was a resounding thump as his fist made contact for a moment before he pulled his hand back. He started to walk back to the Guardians of Light who wary and on edge.
"See nothing happened!" Larxene said before a cracking sound could be heard. The point of impact from the man's hit started to crack and rapidly the entire platform started to crumble as the Earth shattered.
"What?!" The seekers of Darkness yelled in surprise as their platform broke away. They were about to use corridors of darkness in mid air to reappear on the ground unharmed.
However the man had quickly did strange signs with his hands.
"Gale Style: Laser Circuit." AN4 : The man declared as several beams of Blue lights appeared out of his hands and locked in at the airborne Seekers of Darkness at high speed. They hit the prone Seekers making them get stunned as many small explosions appeared teom the impact.
Before anyone could recover or react Sand appeared out of nowhere and surrounded each Seeker of Darkness and covering them so they could not move or do anything except sjout in surprise. The sand slammed them into the ground and pinned them there making them unable to move.
"What the hell is this?!" Larxene screeched as she and the other Seekers struggled to get free.
The man with his head low and his back to the Guardians of Light pointed his hand in the direction of the pinned down Seekers. He shot something that looked like black medal at them and the 6 rods quickly impacted and sunk into the ground at certain formation.
"Six Red Yang Formation." The man said as red energy quickly shot up from the Six medal rods and formed some sort of containment around the Seekers of Darkness making them completely surrounded.
The sand then vanished as the True Organization 13 got up looking around to see themselves in a red containment field.
"Tch. I don't know what this red barrier is suppose to do but it can't contain us." Vanitas said smugly as he put his hand out and gathered Darkness to form a Corridor of Darkness.
The Guardians of Light were on edge much to the surprise of them and the Seekers of Darkness they darkness appeared to fizzle out and dissipate after Vanitas fathered it and was unable to form a corridor of Darkness.
"What is going on here? Come on!" Vanitas shouted in anger as the same result kept happening. The other seekers of Darkness quickly discovered the same results happened.
The hooded man shook his head and crossed his arms.
"Sorry this barrier I midified to keep you inside so even your powers of Darkness cannot get you out." The man told them as he shrugged his shoulders.
Larxene was mad so she pounded against the barrier to no avail and her lightning did not even phrase it.
"Who the hell do you think you are? Huh?" Larxene screeched as the man sighed but put his hands on her hood.
The man took off his hood to reveal a rather handsome blood haired man with bright blue eyes. He had odd markings on his face almost like whiskers as he looked at the Seekers of Darkness with distaste. His expression softened when he turned to the guardians of Light with his eyes lingering on Kairi's for just a moment as her confused expression showed she did not know him.
"Naruto….. Uzumaki…. Got it memorized?" Naruto said pointing at his forehead with his index finger with a smirk as he turned discreetly to look at Lea before he turned and gave a grin to Kairi and a wink.
There was a few moments of silence as everyone took in the strange but very familiar introduction.
Saix was the first to react as his gave a dry chuckle smirking at Lea's abosulte gobstopped expression. Larxene and Xigbar laughed while Luxord chuckled. Even Xenmas snorted for a moment before his expression regained its calm expression. Xion in her hood tilted her head for a moment before blinking as if she tried to remember something but forgot instantly.
Ventus looked at his friend Lea with a smile before he chuckled. Riku smirked while Donald and Goofy looked confused at some kind of inside joke.
Mickey gave a small laugh while Sora smiled and laughed but he felt it was more on Roxas's behalf not his own. Aqua tilted her head at everyone seemingly immature attitude.
Kairi giggled as Lea got over his surprise and pointed at Naruto with an accusatory finger.
"Hey that is copyright trademark!" Lea declared as Naruto gave him an amused look.
"Oh? I mean Kairi copied you once and you didn't mind." Naruto pointed out as he crossed his arms.
"Wait how did you know about that? It was just me and Kairi in that space!" Lea pointed out as the Guardians grew weary of Naruto again.
'And I didn't tell him my name and yet he already knew it.' Kairi thought although for some reason she could find it in her heart to be weary of the stranger.
"Dreams can show us a lot. It can even tell us things we did not experience ourselves." Naruto said vaguely as he grew sad for a moment as eh started to walk towards the guardians of Light. AN5:
Instantly everyone had their keyblades out and were in defensive positions except Kairi who Riku and Sora had hid behind them.
'Who is this brat? He was not in the book or in the Master's plan!' Xigbar thought with anger and annoyance.
Naruto walked calmly not even minding the weapons pointing at him as his focus was on Kairi as his expression was one of happiness and relief.
"Finally after so long I found you." Naruto said looking at Kairi who blinked.
"Hey! Back off!" Riku said protectively as Sora put his hand in front of Kairi.
"You know this blondie?" Lea asked as Kairi shook her head.
"No I have never met him." Kairi said but her heart felt clench when his expression dropped.
"I suppose you wouldn't remember. We were so young and even I didn't remember till just recently." Naruto said sadly as he stopped a few feet away from the wary keyblade wielders.
"I don't know who you are but you are not taking Kairi anywhere." Aqua told him sternly as Naruto briefly looked at the beautiful blue haired woman before sighing.
"I am not your enemy. I am just so Kairi can remember." Naruto tried to tell them but everyone still looked at him suspicouly.
Kairi felt a warm feeling in her heart as she looked at Naruto with confused eyes.
"Who are you?" Kairi asked as Naruto looked straight at her with bright kind eyes.
"I am your brother. Kairi Uzumaki." Naruto declared as there was silence.
"What?!" Everyone shouted.
In the moment of pure shock Naruto zipped past Sora and Riku and placed a hand on Kairi's shoulder as a blue glow from his hand that surrounded Kairi.
"Get away from her!" Sora shouted as Naruto backed away when Riku and Sora swung their Keyblades at Naruto. Naruto avoided their swings and ducked under Ventus's backhanded swing as he leapt into the air and jumped away as Lea threw his Keyblade in the form of his old Chakrams. AN6:
"Kairi! Are you okay?" Sora asked as him and Riku went to Kairi who looked glossy eyed. The blue glow had vanished as Kairi blinked before her eyes widened in recognition.
"Wait! Stop everyone!" Kairi screamed as Aqua and Mickey stopped from tag teaming Naruto who had avoided the attacks of the Keyblade Wielders with ease.
"Its okay." Kairi told Sora and Riku calmly as she walked past them and the other guardians till she was just a few feet away from Naruto who had a neutral expression as if not wanting to get his hopes up.
"Naruto?" Kairi asked hopefully.
"Yeah, its me." Naruto nodded looking down. Naruto was a few feet taller than Kairi who looked rather small compared to Naruto.
Before anyone could say anything, Kairi threw herself into Naruto's arms and put her face into his chest.
"I am so sorry!" Kairi sobbed as Naruto wrapped his arms around her protectively and put his chin on her hair.
"You never have to apologize for anything." Naruto told her as her put her back gently as Kairi continued to cry.
Nobody was more shocked than Sora and Riku who had never seen their childhood friend so vulnerable before as even when she was captured by Saix she kept her spunky attitude.
"What is happening here?" Lea decided to ask the question on everyone mind as Kairi tears soon dried up but Naruto still kept a grip on her.
"Naruto is my twin and he is my family." Kairi declared as she looked defiantly at everyone.
AN2: For people who actually played REMIND (or at least watched the cutscenes) and the Finale of Union Cross cutscenes we know its not really Ven's darkness. It is the embodiment of Darkness that used Ventus as a vessel and MX unknowingly brought it out of Ventus in BBS.
AN3: this is an AU crossover but I honestly think based on the fact it needed '13 clashes of darkness and Light' that it was kinda stupid of Terra-Nort to attack them before the 13 were assembled.
AN4: I know its Storm release but I am using the dub as I don't like having to call everything 'release'.
AN5: He is alluding that whatever dreams he had is how he knows everyone there.
AN6: before I get spammed reviews they don't know Naruto (and as far as they know Kairi doesn't) for all they know Naruto tried to infect her or something. So they did overreact but not because they are aggressors.
