Thorough the Heart and Soul

a Kingdom Hearts/ Naruto crossover

by L33t Horo

Preface: Good night/ Good morning... Darkness/Light

'Where am I?' I look around... only finding darkness, my voice doesn't come out, only my thoughts...

'only darkness... maybe... I died...' I think, as I see in the darkness a replay my fight against my old friend and rival... his mind being eroded by the cursed seal.

'Boy! do you desire to save your friend?' a voice echoed through the darkness, I float still in a small shimmer of light in the endless void of darkness.

'I do' I reply weakly as I feel fleeting. My body is radiating a small white light in the middle of the vast darkness.

'Even if... they don't like you? would you lay down your life for those you love?' the voice asked.

'Of course... they are... my friends' I say.

'Then... is time...wake up young man' the voice said with a soothing tone.

The shimmer of light shut out and I landed on a pedestal... in it was an image of a young boy with brown hair, another of a boy with blond hair holding a key-shaped weapons.

'Who are they?' I ask myself, forgetting my thoughts are still being broadcast to the bodiless voice.

'They are the previous masters of the power you possess in spades... the power... of the heart' the voice said.

'The power... of the heart? how will that help me? I need a powerful weapon or jutsu!' I thought to myself.

'How naive... do you honestly believe that power and weapons alone will lead you to the happiness you seek? You are sorely mistaken child... but it's understandable... after all your best friend tried to kill you' the voice said once more.

I looked down... images of my friends and my teachers flashed before my eyes, I see Sasuke's conscious decision to leave... I shiver in both anger and hopelessness...

'so... am I dead?' I ask.

'Not at the moment, no you are not... however the beast sealed in you is keeping you alive... you done well to fend it from your heart... but I propose we do something about it... I wish to save you... you seem to be a different kind of person... you have the ability to bring light... even in the deepest of darkness' the voice said.

'Tell me... how can I save my friend from the snake' I ask.

A weapon like the ones in the window panel appeared in my hand.

'This is but a copy of the real ones... in order to wield them you must prove your worth, until then you will have this one... a replica... now come... the trial of the kingdom of YOUR heart awaits you' the voice said as the window panel shattered

I yell as I stretch my arm out for someone to save me from the apparently bottomless pit that I was falling to.

What seemed like an eternity I landed before another pedestal, this one had an image of a young boy, and an older one... and a beautiful girl.

'They are the most legendary of the masters of the key blade... the originals of the copy you now wield, their names are Ventus, the one who is like the wind... next to him is his best friend Terra, the strong one like the earth itself, and the lady, her name is Aqua a powerful magician... or jutsu user like you people use nowadays... who is like the water, after their passing a new generation took place...' the 3 are replaced by younger kids, one with pale violet hair, a boy with a playful smirk and brown hair and a young girl with red hair.

'This were the new generation of key blade masters... the boy with violet hair, his name is Riku... fell into the darkness, however even in the deepest pit of the dark his light shone... he protected his friends in the darkness... the next is Sora, his heart shone the brightest of them all... however... the brighter the light...' at this a shadow outstretched from Sora and another darker Sora came out, his eyes were amber and his body black as midnight 'This is the result when he was defeated and turned into a vile creature called a heartless... however, because his heart was strong... he managed to come back from such a cruel fate but at a price' the voice said

Then a blond boy and a blond girl appeared behind Sora and the other girl

'The girl next to Sora, her name is Kairi... and she is a princess... well was... anyways she was the ever gentle soul... her heart was taken from her, the same as Sora... she gave her heart to Sora so he could live on... he fought for his own heart in order to return Kairi's back... due to that they accidentally recreated another kind of enemies... and allies... the nobodies...' The voice said as the blond boy and the blond girl took center stage.

"They are the part that left their bodies, they have no memories of their life... they are only what they are... nothing else... however, this particular nobodies evolved, and attained their own heart... however they had to return to their originals in order to complete the force they wielded, each one individual was strong... however once the nobody combined with his original... their strength far surpassed each as individual... now... if you wish the power they wielded... fight this heroes of the past... and show your mettle' The voice said as Ventus came out, holding his key blade in a backhand position

He made a "come on" gesture with his hand as he smirked

I dashed towards him and jumped, I spun in the air and slashed at him, he smirked as he blocked and disappeared, only to reappear behind me and slash my back

I steeled my eyes on him, I tried the same trick... this time I used the handle of the weapon to block, the kid's eyes widened as I dashed at him and began to attack in a flurry of blows.. however the kid smirked once more and threw a white light at me...

I felt my body freeze a bit and stopped due to shock, the boy smirked at dashed once more at incredible speeds, he then hurled his weapon at me hitting me on the face, as I was blown back the weapon hit me on the back of the head making me go forth and fall down on my face.

I picked myself up, blood in my face, the boy disappeared, in his place was the man, he looked at me with some amusement and signaled me to stand.

I shoved the weapon to the ground and used it to help myself up, the older boy looked at me and nodded in approval, he then jumped, electricity flowed through his weapon and slashed at me, I rolled out of the way just in the nick of time... he the stretched his arm out and circle appeared bellow me, I cursed as I saw white lights above me

Just as I was about to jump, a torrent of thunder rains upon me... I yell in my mind in pain and fall to the floor, my body smoking from the attack...

My eyes hardened as I look at the boy... I grit my teeth... I have a mission to do... I can't waste time... I need to think... something to beat him... I remember what the voice said...

He is the embodiment of power... however power has a drawback...

I put my chakra into my limbs and dash forth, surprising the older boy...I slash at him and jump over him and kick him... I then hurled my own weapon akin to that of Ventus before on his little spar, however, rather than waiting I dashed forth and punched and kicked Terra... the weapon returned hitting Terra on the back as I connected a powerful knee to his face, sending him hurling back.

Terra smirked as he gave me a thumbs up... then after him came the girl... Aqua

She raised her key blade and a green light washed me over and my wounds disappeared

She then cast a white light and everything began to freeze

I jumped this time, knowing what to expect and then hurled the key towards her, however she was nimble and dodged that... wow... wish I knew a woman like that... wait... focus... fight now, think that later.

She smiled sweetly at me but still clashed against me, my weapon meet hers, she then swept me off my feet, literally.

I cursed as I flipped over, only to have the beautiful woman all over me... with deadly attacks from her weapon that is.

I twirled this key blade and grabbed it the same way Ventus had and slashed using speed and agility, however those tricks did not work on her, she was like flowing water, I tried for the 'direct' approach

I used my unnatural stamina and power to fight against her, using every trick in and out of the book, fighting like I was trained to be... a shinobi

She jumped back and tagged the boy with violet hair... Riku was his name.

His body flared with the darkness and his body was covered in a dark armor, his key blade looked odd, dark...

'Like Terra, this boy posses powers of darkness... however his heart is strong enough to work with it... light... darkness... ying and yang, two sides of the soul and heart together... his being the darkness' the voice said

The voice rushed in, he was powerful like Terra... but he was nimble and fast like Ventus

I jumped back and blocked his strikes... he attacked with tendrils of darkness and moved at speeds rivaling the fastest of ninja...

my body was cut to shreds... but I managed to survive... however I was getting frustrated

'Heed my words boy, your heart shines bright.. however... the brighter it shines' the voice said as Riku jumped back as my shadow began to move, the shadows then began to swirl and looked like tails... and began to grow... and took the shape of a monster that made my eyes wide in both shock and terror...

'The bigger the shadow of darkness they cast' the voice said as the kage no kyuubi rose up and roared, I shoved the weapon to the ground to use as a 'foot-hold' to prevent being blown away

'Go... and fight... reclaim your light' the voice said.

I roared to get my nerves back and rushed to the shadow construct, however it blew me away with a single tail... I was beaten and battered, the dark construct then picked me up and tried to swallow me a key blade appeared and cut through the dark tendril that caught me.

It was Sora, another key blade master and smirked, he outstretched his hand to help me up and accepted

'This monster... is your darkness... what you fear to become... fight it... and show me you are worthy of wielding the power of the key blade' the voice said

I stood up and nodded... and grasped the key blade tightly, he rushed at the monster and smacked him around a couple of times, the monster roared and attacked, his tails smacked against me, but I blocked it... taking all the damage and deflecting it

I steeled my gaze to the dark fox and it smirked evilly as it called forth it's minions

little 'rabbit' like creatures...

'Heartless... creatures too weak to resist the call of darkness who have their heart stolen by it' The voice explained.

Naruto roared as he charged at the dark spawns and eliminated them fast, they were not as strong as the dark fox

'Be careful... your shadow is reading to attack... LOOK OUT!' the voice said as I jumped into the air and twisted myself and stabbed the dark fox on the head...

It began to roar and white and black particles began to form around him and exploded sending me hurling out of the platform.

I then landed in a pedestal and 3 pedestal were there, a sword, a shield and a wand

'Choose one of this to make your path... the sword of the warrior who fights for his friends, the shield of the defender who protects his friends, or the wand of the mage the wise one who plans to help his friends... choose young man...' the voice said

'I choose the shield and the sword.' I said with decision

'The power to fight and protect, to shed your blood in the battlefields in the thin hope that you can grow stronger and stronger and become your friend's fortress... poetic I see' The voice chuckled, I frowned at his quip.

'now now... don't be mad... now remember what you learned here, trust your heart... the stronger your heart is... the stronger you will be... remember and pay heed to Haku's words young one... and I hope for your sake, I hope your heart is strong enough to fight the darkness that is fighting against your light and take the key blade that was forged from your heart, the TRUE one and fight for your heart and for your friends' the voice said as a door appeared in front of me...

I open the door and light, colors, scents and feelings washed me over.

'Rise forth Key blade master... go forth and attain that which you seek'

"For my friends" I steel my eyes as I rise from the water as a ball of light enveloped me.

'All you have to do...' the voice said

"Is open the door" Naruto said as the floor gave into light and a window pane of himself holding the key blade on his shoulder as he lay on the wall behind with a content smile, a door appeared and Naruto stepped forth.

-End first Person Point of View-

"You see that dobe! that is the power of the elite Uchiha... with this power... I will AVENGE MY CLAN!" the young raven haired boy shouted with a psychotic look on his face.

As he turned his back a light began to emerged from the waters... it was bright and it was pure white

"SASUKE!" A voice yelled as the light broke into tiny pieces... from it came the fore-mentioned 'dobe'

In his hand he was wielding a comically looking weapon, he twirled around and poised in on his shoulder.

"Ready for round two... teme?" he said looking at him with his eyes steeled on him.

"COME THEN... NARUTO!" he yelled as he charged with a kunai drawn.

Naruto used the weapon to deftly deflect the attacks and smacked him into the mountain.

Sasuke pulled himself out only for Naruto to pin him back into it, and then reared his head back.

"WAKE. THE. HELL. UP!" Naruto roared as he head-butted him with a bone shattering blow.

Sasuke's brain was moving about inside his skull...

"HOW DARE YOU BE STRONGER THAN ME! HOW LONG... HOW LONG HAD YOU HAD THIS POWER AND HID IT AND MOCK ME WITH IT!" Sasuke roared as he held his forehead trying to stop the buzzing and the dizziness.

"THIS IS THE POWER OF MY HEART! YOU CAN'T GET IT UNLESS YOU PROVE YOURSELF WORTHY TO WIELD IT TEME!"Naruto yelled

"STOP MOCKING ME!" Sasuke roared as his body began to be change, his hair turned white... and from his back sprouted 2 hand like wings.

"LET'S SEE WHAT YOUR HEART CAN DO AGAINST MY HATRED... NARUTOOO!" he roared as he charged towards him.

Naruto jumped and slashed at the Uchiha as he attacked him using his sharingan.

Naruto's moves were read almost perfectly, only when he used his key-shaped weapon was his eyes unable to track him.

"W...what's going on? Why can I track him and sometimes not... is it that blade... could it be an anti-sharingan weapon? If so... I must have it... so I can defeat HIM..." Sasuke thought as they exchanged blows with their weapons, Sasuke parrying his Key blade with his kunai and slashing at him, only for Naruto do dodge or block.

The Uchiha then grabbed Naruto's arm and twisted it, and kicked the blonde boy back, "At last...a weapon to KILL HIM!" he roared with a victorious smirk.

Naruto smirked as he stretched his hand out... to Sasuke's surprise the weapon vanished and reappeared on the blonde's hands.

"Nice try teme... but this weapon... is one with my heart" Naruto roared as he attacked...

Sasuke frowned and blocked the hits, the more the fight dragged on the more comfortable the idiot was with this new weapon, he knew next to nothing about this weapon... but he was at a disadvantage.

"WELL THEN... I'LL JUST RIP YOUR HEART APPART!" Sasuke roared as he charged an attack.

"CHIDORI!" he yelled as he dashed at inhuman speed.

"RASENGAN!" Naruto yelled, the key blade pumping power to it as well, making the rasengan white.

The attacks collided...

BOOM !

The attacks collided and formed a black ball and engulfed them both and them imploded sending both kids into the forest (Naruto) and shoved into the mountain side (Sasuke)

Sasuke and Naruto both were hurled away, next to the unconscious Sasuke was Kabuto and Orochimaru, while Naruto sank in the bottom of the lake.

"What just happened a moment ago?" Orochimaru said as he narrowed his eyes...

Not far away

Kakashi and Pakun were close to the Valley of the End...

"Naruto's scent vanished... I think he went underwater" Pakun said.

"Naruto... be ok" Kakashi said as he hurried up.

Back to Naruto

"Kabuto... let's go" Orochimaru said as they vanished, Naruto resurfaced once more.

"Sa..su...ke" he said as he passed out... his weapon vanished as his sensei arrived.

"N..ruto... ruto... hol... on..." he said as darkness took over him.

"Sa...ke" Naruto said as his arm went limp.

Somewhere else

'It has started... the legends have come to be... the awakening of the one who wields the power to open the hearts and reconnect them... the person who can bring either salvation... or ruin'The voice said.

6 key blades appeared on a rock, each a monument for the fallen key blade wielders in each their names inscribed.

'Let us hope that this youth can accomplish the task his predecessors have left for him... and take the mantle... the mantle of a true key blade warrior' the voice said.

'And... let us hope he is also the one... to rid the worlds of darkness' the voice said as it echoed in darkness.
