I don't not own Kingdom Hearts. It belongs to Disney and Square Enix but if I did. The third game of the main series would have been out years ago. I was replaying the games and read some of the other ideas of what would happen in Kingdom Hearts III and I figured what the heck. Let's write a Kingdom Hearts story. I hope you enjoy.

Kingdom Hearts: Birth by Sleep: Sora, Riku, and Kairi's Story

(Theme: Simple and Clean)

Prologue

World: Mysterious Tower

"Thank You, Master Riku, for bring Princess Kairi to join us." Said Master Yed Sid. Riku nodded, "When I asked her and told her the situation. She was more than happy to come along. How is her training coming by the way?"

Mickey then answered, "Gosh, she going along great. Even though she has trained only for a month, she has learned a lot since she's been her. I doubt anyone will kidnap her now." Riku smiled and said, "Sora will be happy to hear that."

"Speaking of which, has he returned from the world of sleep, yet?" said the retired Keyblade Master. Riku shook his head and said, "No, but I have a feeling he will be here we any minute now. I can't wait to see the look on his face, when he sees Kairi here as well."

World: Traverse Town

"Sorry but I have to get going. I'm going to retake my Mark of Mastery soon." Said Sora. He knew he had to go soon and as much he going to miss the Dream Eaters, he wanted to see Riku, his best friend and who is like a brother to him, and Kairi, his other best friend and the girl he had a crush on for a long time, again. All the Spirits look down and Sora heard that they were beginning to wimpier. Sora smiled and said, "Don't worry, I'll be back soon and this time, I bring Riku and Kairi too."

That made them lick Sora a lot like puppies and he began to laugh. "Okay, okay. Just stop. I see you all soon." He waved goodbye and brought out his Keyblade, the Kingdom Key, with that a keyhole was formed. His Keyblade then shot out a bright light and unlock the keyhole with that he was transported away from the Dream World.

World: Mysterious Tower

Both Donald and Goofy watched as the Princess of Heart trained with her new Keyblade, Destiny's Embrace, practicing with some light orbs that Yed Sid made for her. "Grawsh, Kairi, has trained really hard ever since she got her hands on her Keyblade." Said Goofy.

"Yeah, I don't blame her she was kidnapped with out a fight by Axel, Siax, Maleficent and Ansem, I mean Xehanort's heartless. She doesn't want to be the damsel in distress this time." Donald Duck responded. "I can hear you two you know." Said Kairi as she struck down another orb of light.

"Sorry Kairi. We didn't mean anything that you always getting kitten-napped." Said Goofy.

"Kidnapped." Donald corrected Goofy.

"Right, kidnapped." Said Goofy. Donald signed while Kairi giggled at Goofy's mispronunciation. Donald then continued, "We know you just want to fight along side Riku and your boyfriend, Sora."

"Yeah, this time I'll fight. I'm not standing on the sidelines this time. I'll fight with you two, Riku, and..." Kairi then realized what Donald just said as she finished the last orb. "Wait...WHAT!? Sora's not my boyfriend." She denied while trying to hide her blush.

Both Donald and Goofy start to laugh. "Oh, we know you thinking as much about him as much as he thinks about you. Ayuck." Said Goofy. "Yeah, on our first two adventures, your all he talks about." Said Donald.

"He does...?" She asked to herself. Before they could continue on their relationship a bright light appear and Sora came walking with the cloths he received on his second adventure. "Hey guys I'm...KAIRI!?"

"SORA!" She ran to him and gave him a hug, she never wanted to let go of him. Kairi the realized she had just proven Donald and Goofy's point. Sora hugged buck but then saw Donald and Goofy smiling at the couple. They both let go and started to blush. "What are you doing here?" Asked Sora.

"Riku brought me here. Master Yed Sid wanted to teach Lea and me how to use our Keyblades. He thinks we might be apart of the 7 guardians of light." Said Kairi. "That's great! We can all finally travel the worlds together. You, me, and Riku." Sora said with excitement.

"Yeah, every time we try to travel the worlds together, something happens and we all get separated. At least you and Riku are starting to travel together." Said Kairi. "Not this time. This time we're all travel and fight together. You, me, Riku, the King, Donald, Goofy, Axel or Lea, and then when we save the people who are hurting, they can come with us too." Said Sora. He wanted to show all his friends of the many friends he made with Donald and Goofy.

"Or you two can just daze off as usual." Said Riku as he exited the tower. They turned to Riku and Soa said, "Hey, Riku. Oh, wait, it's Master Riku now."

"Oh, that's right! You passed your Mark of Mastery." Said Kairi. "I still believe both Sora should have passed as well. It's not your fault we walked into Xehanort's trap." Said Riku.

"Hey, you saved me and your heart became immune to the Darkness. I told you you would pass with flying colors." Said Sora. Riku then pointed out, "If I recall correctly, you said we would both pass but when we met up with each other, I find you taking a nap."

"Sora, you lazy bum, you just keep finding ways to take a nap whatever your doing." Said Kairi with a smile she was Sora kept his promise and never changed. However, then smile turned upside down and ask, "Wait, what did you mean by trap?"

Both Sora and Riku were a little heisted to tell her the whole story at first but eventually they told here the adventures of the dream world, along with revealing that Ansem (Xehanort's Heartless), Xemnas (Xehanort's Nobody), Xigbar, and Saix, had all have been revived and reformed Organization XIII. It was all thanks to the young time traveling Xehanort and if it hadn't been for Lea, Donald, Goofy, King Mickey, and Riku, Sora would have become one of Xehanort's vessels. Kairi gasped and said, "Is that the reason Riku passed? Because he was will to go through all of that to make sure Sora would walk into that Xehanort freak's hands."

They both nodded. They both saw Kairi now looked a little worried for Sora's safety. Sora comforted her and said, "I'll be fine, Kairi. Xehanort won't get the jump on me next time and if he dose I'm sure you be able to pull me out of his grasp and kick his butt."

Kairi smiled as she hugged him back, "That's true." Riku smiled and said, "Okay, love birds. Master Yed Sid and the King wanted us to all to meet him upstairs." The let and blushed when Riku called them love birds. Donald and Goofy continued to laugh and their embarrassment. The five friends went upstairs and met up with King Mickey and his old Keyblade Master, Master Yed Sid.

"Sora, I see you have returned from the realm of sleep." Said Yed Sid. Sora nodded as he put his hands behind his head and said, "Yeah, I ready to retake the Mark of Mastery."

"Very good. Now we need to hear from Lea to if the Hollow Bastion Restoration Committee has found any clues of what Xehanort or Malifacant next move are." Said the former Keyblade Master. Right on cue, a Corridor of Darkness open and Lea walked out and said, "We've got a problem."

"Gosh, what is it, Lea." Asked King Mickey. "Tron pick up multiple time shifts across the worlds. Some are changing into dark and creepy worlds while others had fallen into darkness. Got it memorized?" The former Nobody explained.

"WHAT?!" nearly everyone in the room shot out except. "As I feared, Maleficent must have found the Book of Prophecies so where in the past and Xehanort must be using this to his advantage." Said Yed Sid.

"Then it fortunate, that I came right on time." Said Merlin as appeared in the room right next to Lea. "Merlin the Wizard! How's it going? Did you find a solution?" Asked Sora.

"Yes, but I will need a little help from Yid Sid and Naminé." Said Merlin. Kairi looked confused, "Naminé? As in my Nobody, Naminé?"

"The same. Could you summon her? Sora you might want to summon Roxas as well. He may want to hear this" Said Merlin. Sora and Kairi nodded and soon ghost images of their Nobodies appeared before the heroes of light. "Hey, Axel. It's great to see you again." Said Roxas.

"You too, buddy and by the way, the name is Lea. Got it memorized?" Said Lea. Roxas nodded before Naminé spoke, "So, how can we help?"

"Sora, remember when you, Donald, and Goofy, had to stop Pete from changing the past on Timeless River." Said Merlin. Sora nodded and said, "Yeah, you summoned a door to that world and had me lock the other door shut with my Keyblade. Wait, you don't mean…?"

"I'm afraid so. Not only has that door been unlock but also it has been altered by Maleficent to send someone into 10 years in the past. Because of that door it creating keyholes across the past allowing both Heartless and Nobodies alike to travel to the past. It's even dragging worlds in the present to the past." Said Merlin. Sora, Donald, and Goofy all signed. "Not again." Complained Donald.

"Okay then we need to find that door and lock it shut." Said Sora determined to stop Maleficent. Yed Sid merely shook his head, "I'm afraid it's not that simple. The door on Disney Castle only leads to the Timeless River. Maleficent used powerful and dark magic to alter it. It's easier said then done with light magic but if an old Keyblade Master, a powerful wizard, and a witch of memories use their powers just right we may be able to alter that door to follow Maleficent and fix everything that she has done."

"Yes, but I can connect to Sora's memories and those who are connected to him. If you said was true, then if Sora, Riku, or Kairi enter that door and it's not done right the could appear there with the appearance of 5-6 year old child and they wouldn't be able to use their Keyblades. And if I do it on anyone else who are old enough, the would need the ability to wield the Keyblade." Naminé pointed out. Merlin nodded and said, "Yes, the others may not work even Mickey who had only became a Master recently at the time would be able to work but that's where Roxas comes in."

"But I wasn't around at the time." Roxas pointed. Master Yed Sid nodded and said, "That is true but Sora had somehow made a special connection to another Keyblader at the time from the moment he was born. Therefore, making you the Nobody of two people. Sora and Ventus."

"Huh, now that I think about it you do look allot more like Ven than Sora." Said Mickey. Naminè nodded, now understood what they were saying, and said, "So that means, I should be able to go deep in his memories and help your alter the door using the memories on the same day that Malifacent, Pete, and the Organization came into the past."

"Correct. Sora, Kairi. Consider this your Mark of Mastery. If you succeed, one of you or the both of you will become Masters." Said Master Yed Sid. Both Sora and Kairi were stood there and awaited their instructions. "First, let's talk about one more creatures of Darkness you will have to face in that time period."

With a swift of his hand blue creatures with red eye appeared before them. "These creatures of darkness are ones created on negativity. They are those who were not well-versed in their own existences. They are called the Unversed. The ones you see before are called a Flood. Like the Heartless and Nobodies, they are various kinds of them. Each with their own weapons and powers and they too fear the Keyblade."

"This feels familiar." Sora said to himself but then went back to listen to what Yid Sid said they had to do. "Now, you already know about the Heartless and Nobodies and you know how they are coming there but you should know how to prevent them to prevent them from the past. First you must find the keyhole of where they are coming from, then two Keyblades must be used to lock it one from the past and one from now. You will have to work with Master Eraqus pupils to accomplish this. Should you stumble on a world from this time, you find that world's keyhole and lock it and the world should return to it's proper time. Once all the keyholes are lock the door to the past should appear. Then lock it with you Keyblade and return to here."

"Finally, while you are there, you should find out what befalls Terra, Ventus, and Aqua. Then we will do everything in our power to bring them back to the Realm of Light. Master Riku shall join you incase Xehanort for this or that time has any traps in store for you. If you succeed you shall both be Masters." Said Master Yed Sid. "Don't worry Master. This time me and Kairi will pass this with flying colors!" Said Sora.

Master Yed Sid nodded and said, "Good. Now before we begin, I have one last gift for you."With a swift of his hand, armor pads appeared on each of the Keybladers shoulders. "Umm…what's this?" asked Kairi.

"Back then Gummi Ships hadn't been invented, yet. Keybladers wore armor to survive space as the used their Keyblades to travel from world to world."

"Wooooww….I can't wait to try it." Said Sora. Riku smiled. "Sora, you are such a little kid sometimes. You will be impressed by anything and still believe that Santa Claus is real." He thought to himself.

"Now then lets get that door for you, then." Said Merlin. With a swift of their hands, Merlin, Yed Sid, and Naminé summoned the door. Merlin the turned to Sora and the others, "Now remember, Sora. As long you enter that door a dark temptation will want you to change the time somehow. You and your friends must resist that temptation at all times." Said Merlin.

"Got it." Sora said with a nod. Riku and Kairi nodded as well. "When you arrive at the Land of Departure seek Master Eraqus. You may inform him or me that you came from the future and inform him of the situation at hand. The other Keybladers though will have to figure it out on their own." Said the retired Keyblade Master.

"Don't worry we'll make Sora doesn't slip up." Said Riku. Sora then glared at his friend, "What's that supposed to mean?"

Everyone began to laugh and even Sora joined in eventually. "Well, we better get going?" Sora, Riku, and Kairi headed for the door before Naminé stopped them. "Wait, there something else you should know. As soon you enter that door, as a side effect you won't remember who Xehanort is, you'll remember his other versions of himself and his plan but you won't remember his name. This should last only for a week but I thought you should know." Said Naminé.

"So, we won't remember what is real name is or who he looks like for a week. Is that it?" Asked Riku. "Yes, you should still remember everything of your lives and adventures." Said Naminé.

"Then we have nothing to worry about. As long as we have each other we'll be ready for anything that he or Maleficent throw at us." Said Sora. "Sora's, right. As long as we have each other, then we shouldn't have any problems. Plus he'll have to deal with 6 Keyblades instead of 3." Said Kairi.

"Make that 7. I had a Keyblade with me, back then too." Said Mickey. "Hey, wait a minute. Why can't I come?" asked Lea.

"Because Master Eraqus has always told his students to turn away from darkness and will see you as a threat." Master Yed Sid explained. Lea signed in defeat. Roxas then put his hand on his shoulder and said, "Hey, if we need back up. We know you'll be there. Get it memorized."

"You got it." Said Lea. He remembered that he made a promise to always bring Roxas and Xi- some else back. "That was weird. Who was I thinking about before?" Lea thought to himself.

"Good luck, Sora." Said Goofy. "By the time, you get back we fight along side you as a master." Said Donald.

"You bet." Said Sora. He turned to his first two best friends. "You guys ready?"

"Ready when you are." Said Riku. "Yeah, let's do this together" said Kairi.

"I'll race you." Said Kairi. "What?" asked Sora.

"Kairi, we are supposed to be professionals. We not supposed to make this mission." Riku agrees with Sora. "Ready, GO!" said Kairi.

With that both Sora and Riku raced to the door, with Kairi giggle right after them. The next big adventure had just begun.
