New A/N 11/18/2017: This story is currently in rewriting. Any and all chapters that are rewritten as of today will have a "Re:" in the beginning (See the title of the chapter below). I took a look at the already done work, and it's just shouting, "CHANGE ME!" and yes, I am changing the nature of this story. It's especially prevalent on the earlier chapters. This may upset some of you, but a majority of these worlds are from Kingdom Hearts II, and if the plot of these worlds are Kingdom Hearts II, it might as well be Kingdom Hearts II, and it's exactly that. This story will now take place DURING Kingdom Hearts II. I mean, Volume II would be taking care of Organization XIII, and because of the nature that I'm going with in this story, I actually do want this to take place after Kingdom Hearts 1 and Chain of Memories and 358/2 Days. Plus Knight of Loyalty already started off their crossover series with Kingdom Hearts 1, so I really wanted to do something different (And also, I still like the original Adventure 01 anime, so I am kinda biased there). Just please roll with me here...

I'll leave the other chapters up to not erase all the hard work I've put in through the years, but they will be rewritten soon. Another thing to note is that this may become a T rating, as I plan to flesh out the worlds a bit, including the lore of this universe, and it may/will become darker than it already is.

Oh and also, I'm trying to go for a bit more originality, as I will be changing up the designs of the Keyblades. I like 1sthi1357's designs, I really do, but I kinda used the designs without their permission. Plus I want to go for some originality in this story. I mean, my Keyblade designs will probably have some aspects of other Keyblades, both official and fanmade, but still, I'm trying for more originality. I'll be drawing them as I write on, and I'll most likely post them on my dusty Deviantart account (Man, it has an old Kingdom DigiHearts sketch, AND an Everything Wrong With script? Man...). They will be sketches, and not really colored (As I don't have the utensils at the moment), so be aware.

As of another side point, I recently watched KH X Back Cover. *Sigh* It's good to hear Lara Jill Miller's childlike voice again, even if the Chirithy is the narrator, and if it only has one line in the movie.

Old A/N: Due to Copyright issues I heard with Song lyrics, I have to take them out of the intro. When the final chapter comes out, the song will only be there for a little while...Probably, unless I see someone get away with lyrics in their fanfiction.

"Thinking of you wherever you are,
We pray for our sorrows to end,
And hope that our hearts will blend.
Now I will step forward and realize this wish.
And who knows?
Starting a new journey may not be so hard.
Or maybe it already has begun.
There are many worlds,
But they share the same sky–
One sky, one destiny…
One light…"

A young girl in a sleeveless yellow shirt, magenta pants, red and white shoes and pink scarf was slowly waking up from some sort of slumber. Her eyes fluttered open, and she sees that she was falling down some sort of bottomless pit underwater. This didn't make her frightened or anything. She was curious.

Where was she going?

How did she get here?

How can she breathe in here?

What was happening?

As she was falling, Kari Kamiya was thinking to herself in her mind…

I've been thinking of these weird things lately…

Like…the light and the dark…I've never been thinking of these things before…

I've known that there is light in darkness…

…but…is there darkness in light…?

*SIMPLE AND CLEAN (Planitb)*

Kari was falling down through some pictures of her and her friends defeating the evil Digimon in the digital world. It was all of her memories that she has. All of their adventures have been sticking around her for a while. Some good, and some bad. She dived faster twirling like a torpedo in the water. She opened her eyes to be in the park. There were kids running all around, with some at a party. She thought she saw Gatomon, but when she stepped forward, she was gone.

Gatomon looked surprised, and couldn't move. All the other people in the park couldn't move either.

All the other Digidestined kids and Digimon were there. T.K. and Gatomon held out their hand to Kari, yelping for help.

Kari sprinted towards them, but she wasn't running as fast as she could. When she almost reached them, they disappeared. She was then swimming in darkness, as it piled onto her.

She was immobilized in the darkness. She opened her eyes to see everyone floating in the darkness, unconscious.

Kari tried to move her hand to T.K. and Gatomon first, but she couldn't reach them. Eventually, her chest shinned a white light, and it was lighting up everything in the darkness, blinding everything.

She awakens to be in a meadow at sunset with her friends, the Digidestined and the Digimon. T.K. and Gatomon were with her, as she sat up very fast.

Kari tells them it wasn't something to worry about. It was just another nightmare about…a boogieman? Clearly, she lied, but they laughed together, but then T.K. saw something in the sky.

Kari noticed him, and looked at the sky too. She saw a mysterious figure, along with a meteor shower.

Kari, T.K., and Gatomon were looking at the sky suspiciously, as they try to see what the figure was, as Kari got up.

It was a key shaped object, and it was coming fast. Even though Kari has never seen this object, she looked shocked, as if she recognized this key.

The object crashed onto the land, exploding a tremendous amount of light.

She and the others were thrown back, but mysteriously they all fell through the ground, and was going towards a very deep and dark ocean. They were all falling slowly. T.K. put out his hand at the last second, and Kari tried to grab it, but missed.

Kari was falling head first down, and she was glowing, like a meteor. She could be seen from an island, where three people were watching. One teen that stood out was a teen with red hair, that looked like her. She even had her hairstyle, and a little like her face.

She crashed into the water, and was diving down the dark endless pit again. The memories of her past are coming back to her through the picture rectangles. The Digimon she saw being killed in the digital world, Wizardmon, meeting Gatomon, and having pneumonia.

Next think Kari knows, she was falling down the middle of a large spiral staircase, that seems to keep going up and up towards the light, as she falls down to the darkness.

She saw a boy fighting black creatures, along with 2 anthropomorphic animals. They looked at her, as she was falling towards them. The boy tried to reach for her, but couldn't. For a slight second, it looked like he changed appearances. He now looked like a blonde boy, that is not T.K. or his brother Matt, with a rather light-colored outfit. Kari looked like she was changing into somebody as well, but she didn't.

She kept falling down the abyss, with all of her friends doing the same. However, it looked like she was diving faster, while everyone else was diving slower, leaving her to go down into the deepest parts of the abyss all alone. A bunch of pictures of that same boy's adventures showed up around her. She didn't know any of his adventures, but, it feels like she knows of these adventures somehow. She has never been with this teen, but…he feels all too familiar…She finally got on her back, while floating, and gently lands onto solid ground, finally, onto her two feet. She looks around where she is. She takes a step, and a light shined, as doves flies out of the ground, and slowly, the ground was revealing a stained-glass floor. At first, she sees her crest of light alongside Gatomon, but then the ground was showing the bigger picture. There was 7 bubbles surrounding the Crest of Light. The 7 bubbles had the faces of her friends with their Digimon. Kari looks up as the doves flew away, wondering where she was brought to…

*DESTATI*

After diving into an abyss, Kari ponders where she is. Wherever she is, she wonders if it was somewhere high, as her pink scarf, and hair was flowing slightly, as a breeze was pressing upon her.

"Where, am I?" Kari said. She wonders about the platform she was on. "Wh-Where's Tai? Where's anyone? Hello!?" No answer. She then paid attention to the stained glass picture below her feet. "And, what's with this thing? Why are my friends and the crests here?"

The Darkness is nearing you

"Wh...Who's there?"

There's so much to do, in so little time.

"What?"

Your Heart is still weak...Take your time...

"My heart? What do you mean, it's weak? Does, a doctor need to look at it?"

The first, is power. It sleeps within you.

A shield appeared to the left of her on a tablet.

If you give it form...

A staff with a shape that resembles a cartoon mouse's head on the top of the rod appeared on her right.

It will give you strength...

Then a sword appeared in front of her.

Choose well...

"Power?" Kari wondered. "What am I doing here?" Not knowing what she's doing, she picked up the Sword.

The power of the warrior...

Invincible Courage...

A sword of terrible destruction...

Is this the power you seek?

"Uh...Maybe not?" Kari said, putting the sword back. She jumped down the tablet. "Invincible courage? That's usually Tai's thing, and I don't think I need that much power." She walked over to the staff.

The power of the mystic...

Inner strength...

A staff of wonder and ruin...

Is this the power you seek?

"Inner Strength?" (What to do. The staff seems to show my inner strength, which is maybe the power of the Crest of Light I once had. The sword seems to show, maybe my outer strength? I do want to help my friends, but maybe strength in my body is not the answer. Strength in my heart could be it.) As she was thinking this, she snapped back to reality. (Wait a minute, what am I doing? Why am I doing this? I don't even know what I'm going…*Sigh* Maybe I should just stick with this. Maybe I'll get an answer sooner or later…) "Um, okay." The staff disappears from her hand, and the sparkles flowed into her body. She could feel the power flowing through her veins. She looked at her own arms and hands.

Your path is set...

Now what will you give up in return?

"Give up in return?" (Why am I doing this? What's this for? Is this some sort of prank? Am I in the Digital World again?) All these questions were flowing through her mind. (Hmm...Now what's the Shield for?) She walked over to the shield.

The power of the guardian...

Kindness to aid friends...

A shield to repel all...

You give up this power?

"Aid friends?" (Ever since the Dark Masters and Myotismon hurting harmless Digimon and humans, I wanted to protect those who are innocent. I didn't think I did much to help. But, now I want to help as much as I can if something comes up again. I don't want to risk my friends' lives just to protect mine…I want the power fight against the bad guys to protect everyone…) "No." She sets the shield down, and walks over to the sword. "I give this up." The sword disappears from her hand.

You chosen the power of the mystic...

You given up the power of the warrior...

Is this the path you seek?

Kari nodded, confirming. Then, the tablet she was on collapsed into the platform. It was shaking.

"Wh-What's going on!?" Then, the platform she was on shattered underneath her, and continued to fall into the endless abyss. Her screams were silent, as she fell.

After a while, Kari saw she was headed for another stained glass platform. The picture showed a teen with brown hair, holding some sort of giant key. His eyes were closed, as if he was sleeping. There was also 4 other people in bubbles. One of them is a boy with silver hair, the other is a girl with red hair, and the other two are an anthropomorphic duck and dog, with clothing on. The young 8-year-old then gently lands onto the platform, looking around her again, wondering how deep this abyss can get. The staff she picked appeared before her, in her right hand, in a shimmer of light.

You've gained the power to fight.

"Wha? Fight? All I can do right now is just swing this around. I can't actually fight."

You must not rely on others to fight for you.

(…It could be right. I just stood behind my Digimon, Gatomon, and just let her fight for me.) She just sits in the sidelines, watching her Digimon do all the fighting, but most importantly, watch her get hurt…

She did get the hang of swinging the rod around for a moment. She grips it with her two hands, and holds the weapon besides her, in a fighting position, with the tip of the staff pointing downwards. Regardless of not fighting before, she feels like she has done something like this before. It was all in the heart…

All right! You've got it.

Use this power to protect yourself and others.

She then sees black creatures rising up, from out of nowhere on the platform. These are small black creatures that have small antennas on them, with sharp claws from the looks of it.

"Wh-What are those things?" Kari said. "They, look like Digimon." She was backing up a little, considering these things looked dangerous. They may look cute, but they do look dangerous, at the same time.

There will be times where you will have to fight.

Keep your light burning strong.

Light burning strong. That's one thing Kari will always do. She is the Digidestined of Light. One of the shadows tried to hit her, but she quickly backs away. "S-Stay away!" She shouted. She kept hitting them with the staff, protecting herself from the mysterious creatures before her. Her heart was pounding with fright from both the creatures, and the Darkness from them. Kari swings at one that was about to lunge at her, and it disappears. It definitely wasn't a Digimon, since it showed no signs of being data. She managed to swing 360 degrees, after a few swings, and managed to defeat 2 more. "Wh-What are these things?" The remaining one sunk into the platform, and darkness emerged from the ground. It was spreading to the ends of the platform. Eventually, it reached the place under Kari's feet. She begins to sink into the ground, as if it was quicksand. "Wh-What!? Help! Somebody!" She then sinks under the darkness, and wasn't to be seen.

Kari was squirming all over the ground, trying to shield herself from the darkness surrounding her. She eventually open her eyes, panting hard, to see she's at some sort of beach, with the light of the sunlight beaming down upon her.

"Huh? Am I, at a beach?" Kari said. "I'm glad I'm out of that crazy place, but, where am I?"

Hold on, first tell me more about yourself.

"Not again. What do you mean?" She sees some sort of girl in a yellow dress, below a bridge to a small island, and a similar looking hairstyle that looks like one of her friends back at home. "Sora?" She walks to her, to see it's not her friend Sora. "Who're you?"

"What's most important to you?" The girl said.

"Huh?" All the girl did was ask a question to her, right when she walks up to her.

"Well?"

"Uh…My friends. Why?" The girl disappears. She was startled. "What's going on?" She then sees someone in a yellow outfit, and have a blue bandana on, and holding a volleyball, on the small island. She got on the bridge, and then walked towards the person. "Uh, hi."

"What do you want outta life?" The person said.

"Again? Well...maybe, to protect my friends." The person disappeared, and Kari was still weirded out with what was happening. "Why is this happening?" She looked at the big island she was on again, and saw a familiar friend to her, in a green shirt, brown pants, and a green hat, with a little bit of yellow and blue. "T.K.? Is that you?" She was excited to see her best friend over there. She jumps off the bridge, and into the water. She swims over to her best friend. "T.K.!" Then, as a bright ray from the sunlight got into her eyes, it was a mirage. It was some other blonde kid. "You...You're not T.K...Who're you?"

"What are you so afraid of?" The kid said, in a courageous voice, like Tai or T.K..

"Afraid of?...Maybe...to see my friends hurt." The kid disappears, and this time, Kari wasn't so surprised. The voice came back.

You care for your friends...

You want to be strong enough to protect them...

You're afraid to see the ones you know and love hurt...

You have proven yourself to be who you exactly are…

"What? Who I am…?"

Your journey begins at the dead of night...Your road won't be easy but a rising sun awaits your journey's end.

"Night?" (So, whatever this journey I have to go on is, it starts in the nighttime? All I remember was falling asleep in my bed. Does this mean that...this is my journey right now? This must be...This can't be a dream. It must be real.)

The day you will face against darkness is both far off and very near.

Kari felt the relaxing rays of the sunlight, fall upon her face. She envisions her and her friends having fun at a beach like this, especially Gatomon. Though she'd hate being in the water. She would see Tai and Matt having a water fight, Sora and Mimi passing around a beach ball, and would offer Kari to come play with them; she would see Joe and Izzy hanging around the beach with the Digimon, and T.K. walking up to her, asking if she wants to make a sand castle together. T.K…

She closed her eyes, wishing to get out of there.

But, her wish didn't come true. As soon as she opens her eyes again, she was back in the strange dark place. She was on a stained-glass platform that showed a picture of a road in the dark night, going towards a heart-shaped moon in the distance.

"I'm still not out?" Then, the mysterious dark creatures started to surround her. She backed off, and stared at the creatures all around her. Then, the staff appears in her hands, and she stares at it in curiosity. The creatures tried to hit her, but she managed to dodge them, and hit back. Although, even though she did get the hang of fighting a bit, she did trip, and fell onto the ground. She swung out the staff, trying to scare off the mysterious creatures. "Stay back!" She managed to stand up again. She then swung the staff downwards, and towards the right, and managed to destroy some of them. The shadows phased into the ground, and went past Kari, and rose up from behind her. Its claws felt sharp, cold, and filled with darkness, as it slashed Kari's back. She gets away, holding her back, and yelping in pain. They sorta remind her of her partner's claws, only they didn't sink into her skin, like these creatures are doing. "T-That, really hurts." She keeps on bashing the mysterious foes. She wishes the Digimon were here to help her. Again, the claws sunk into her stomach, and she winced in pain, though they didn't show a scar. She still continues to bash at the mysterious shadows, and eventually they were all gone. Kari was panting hard. "Please tell me, this is it. I can't this take anymore."

Then stairs appeared, along with another pillar. "I hope that's the way out of here. I want to get out of here." She runs up the stairs, hoping there would be freedom from the seemingly never-ending prison. She reaches it, and saw the stained-glass picture below her feet. It was someone young, like a child, wearing a white robe, with the hood over their head. There was also a giant Key that they were holding, alongside with 7 differently colored silhouettes all who look familiar. "What's this?" She saw the light shining down from above. She then thinks that it could be the sunlight shining down towards her from the surface. "Could that be the way outside?" She walks near it, and sees it's right above her head.

The closer you get to the light, the greater your shadow becomes...

And the smallest of darkness can become your greatest threat...

Kari payed no attention to the voice. She kept staring at the light, a little bit hypnotized by it. This crazy place seems to be deepening her connection to the light, as this simple light, shining from the dark skies was enough to completely put her into a trans. She wasn't blinding her eyes just by looking at this single light coming from the sky. She feels like holding her hand up to touch it. But then, she sensed a big dark force behind her. She froze in fear, and then slowly turned to look behind her. It was another dark enemy, which had a giant heart hole in its middle, and looks like a giant. She slowly walks back.

But don't be afraid...

Kari was still walking back.

And don't forget...

The dark enemy had long tentacle like hair. Kari gasped in horror, and started to run, but totally forgot she was on a platform, and almost fell into the endless abyss. Its yellow eyes pierced her heart with fear, as she turned back. She had a little bit of sweat on her face. Kari was trembling from head to toe, like she usually does when she's scared out of her life. She felt like she was going to curl up onto the floor, and cry in fear. The beast then slams its hand down, and darkness surrounded it. More creatures rose up. Kari wanted to go on, and run away, but she figured the only way to escape this place was to fight for her life. So she stands up, and is trying to be brave, as she faces the monsters.

When darkness grows, and the merge begin, the chosen lights must step forward, with the key from within.

"S-Stay calm Kari." She told herself. "D-Don't be afraid. Don't be afraid...like Tai or T.K. would have done..." She exhales, and starts to calm herself down. All she did was remember what T.K. did for her, while battling Piedmon, and she was fine a few seconds later. The rod was summoned into her hands, and she bashed the hands of the giant beast, and dark creatures. Kari just trusted her heart, and she was able to fight fine. Then, the giant beast fired orbs from its heart hole in its chest, and it hit Kari. She was able to avoid the rest of them. Then, the beast slammed into the ground again, spawning more of the creatures she encountered. She bashes them with the rod, and the beast as well. Again, the beast knelt down, and started to blast orbs at Kari. She avoids them all, and then strikes back. It was rinse and repeat. It slammed into the ground again. Unfortunately, Kari was busy trying to strike the beast, she got slashed by the claws of the demons surrounding her. Again, the darkness was knocking against her heart, striking her with fear again. "N-N-No. Have to keep, fighting. It's what Tai could have done." She then kept striking at the gigantic dark beast. The dark beast then shined a bright light on its head. Kari saw the opportunity to strike the head. She threw her weapon at the monster, and that was the finishing blow for it.

"I...I did it." Kari said, panting. All the smaller dark creatures that was supporting the monster was gone. Unfortunately, the monster slammed onto the ground, knocking Kari down. She laid painfully on the ground, while the monster slammed its hands around her tiny body. A pool of darkness then appeared under her, and it was trying to sink her into there. She watches in horror, as she was sinking into the darkness, and as she tries to squirm free.

But don't be afraid...

"Help me! Tai! Anyone!" Kari screamed in horror. There were dark arms rising up from the pool underneath her. The arms grabbed one of her legs, holding it in place.

You hold a mighty weapon in your heart...

Her hand was still free, and was trying to get her arms free from the monster's hands, but the arms from the pool of darkness started to grab them, and hold them in place. Kari feels the darkness entering her body. Her vision starts to fade, and she starts to faint a little.

So don't forget...

The darkness was then covering her body, and face. She gasps in horror, as this could be the last bit of air she could breath, as the monster sinks the young girl into the depths of the darkness. She could see nothing, but darkness. Her entire body was being overwhelmed by the darkness, and the it was proving too much for her small body to handle.

*ENDS*

You are the sole protector of the light...You will light the darkness...

It is your destiny…

…May your heart be your guiding Key…

Kari awakens to a familiar voice she hasn't heard for a while, while she was in the strange abyss.

"Hey Kari!" Her brother called out. Kari shot up from her bed, panting. Sweat was rolling down her head, and was making her pajamas a little damp. She looks at her older brother, who looked concerned. "Are you okay?"

"Was it, a dream?" Kari said, panting a little.

"Usually you're the one who wakes me up." Tai said. "Come on, sis. Breakfast is going to get cold." He then walks out of the bedroom, as Kari holds her forehead, and sighs.

"That place looked too real." Kari said. "It couldn't have been a dream...or was it...I dunno." She then remembers how traumatic the experience of being pulled into darkness was. "T-Those, dark arms…and those dark monsters…those were so scary…" She shivers in fear, as she remembers the nightmare. It was from this point forward, that Kari starts to fear the darkness. She fears of the evil beings that could use this type of darkness for their own evil deeds, and with this type of power…Kari wouldn't even think of it. She is a little bit too scared to think about it anymore.

Kari still was sitting on her top bunk bed. She looks outside, at the morning sunrise, yet, there's no sign of any danger. Perhaps the whole destiny thing really was in her imagination…Or, it really was a sign for what's to come…
