Kingdom hearts dimensions war Phase 0: The beginning of new dimension guardians

This is fanfiction and I don't own anything except original characters that I created.

Episode: The meeting of two girls.

Kairi appeared where everything around her is blue sky, green grass and beautiful flower.

"Where am I and what is this place?" Kairi thought while she was looking around her then man in white T-shirts, blue jeans and black sneakers appeared in front of her. She surprised she step back immediately and summoned her keyblade.

"Who are you?" Kairi asked him.

"Calm down, I know the man that you met before. My name is Remer. " Remer introduced himself.

"I'm Kairi but do you know him?" Kairi asked and he nodded.

"All right please follow me, I will lead you to where he is right now." Remer said and they walked to where they will meet him.

Giant Sakura tree(Big cherry blossom)

Kairi and Remer walked until they arrived at giant Sakura tree. Kairi looked to this giant sakura tree that it had many beautiful cherry blossom flowers and the wind blew their pink petals to Kairi and around the area.

"It's so beautiful. What is this tree?" Kairi asked Remer.

"Cherry blossom tree or Sakura tree in Japanese language and this tree is special because it will always bloom." Remer explained then they enjoyed looking at Big cherry blossom tree until man of light who wore white coats appeared behind them.

"So you came here just as I said." Man of light said then Remer and Kairi turned around and saw him.

"Where am I? When I though a word that you said then I was here at this place." Kairi asked man of light.

"This place is the place that special to you and special to me too." Man of light said.

"Why is this place special to you and to me?" Kairi asked him.

"You will figure out by yourself but now I prepare something for your new journey." Man of light said then he picked three cards from his pocket. These card had same shapes as card at obilivion castle and the fronts were had different shape. First one had a picture of document icon, second one had a picture of wallet and the third one had a potion picture.

"These cards, I feel like I had seen it before but why do I need this?" Kairi asked then she picked all of those cards and put them in her skirt pocket.

"First, you will need this for your new journey especially this first world, second if you want to use those cards you only need to say get while you're holding one of those cards." Man of light explained.

"How do you know that it is important for me?" Kairi asked him.

"You will know that it will important to you later but I need to give you something." Man of light said then rainbow orb appeared on cherry blossom tree then it entered inside Kairi.

"What is that? Did you give something to me?" Kairi confused about what had happened.

"I will give you something that it will be your power for your new journey but I won't tell what is it?" Man of light said.

"How am I suppose to know about what happen or something that you had given to me? There are too many secrets or mysteries that you had kept it from me." Kairi argued angrily.

"You will have to figure it by yourself but we don't have much time because it had already begun." Man of light said.

"Do you mean new dangers?" Kairi asked. Man of light and Remer nodded.

"Alright we will talk about this later but what I need to do next?" Kairi asked.

"Now you had everything so the other thing left to do is this." Man of light said then he flicked his finger on his right hand then big white teleport gate appeared beside him.

Teleport gate had oval shape and it had light blue mix with white colors.

"You remember this power, don't you Kairi?" Man of light asked her.

"I know that if something worse happen. I need to think about the place I want to go then shot beam of light to somewhere for opening the gate." Kairi answered.

"Yes that's correct, you will find more about everything you doubt during your journey but if you are ready then please enter this gate." Man of light said then Kairi checked everything like 3 cards that she had gotten from him, Gummiphone and her keyblade.

After she had checked everything she walked to in front of teleport gate. She looked back to him.

"Are you sure that this journey will be the answer for me?" Kairi asked him last time.

"The answer will appear during your journey." Man of light said.

"All right...Here I go!" Kairi said then she walked through warp gate and it closed by itself after Kairi had entered.

Remer looked to man of light then he looked to giant Sakura tree.

"Are you sure that you won't explain her everything?" Remer asked him.

"If I tell her everything that I had known she won't believe them and it's the journey for her to fix everything that will happen in the future. I hope she will be ready for this." Man of light said sadly then he looked to giant Sakura tree.

Inside teleport gate.

"AAHhhhhhhhh!" Kairi was screaming while she was falling down. Everything around her was too dark that she couldn't see anything except herself.

"Why you won't tell me that I will fall down so fast!" Kairi screamed angrily while she was falling down.

Kairi kept falling down until the light shined so brightly on her body. She felt painful too.

"What...What happen! AHHHHH" Kairi screamed painfully and the light shined through everywhere.

? (Dark time)

"Hey, are you okay?"

Kairi opened her eyes slowly then she saw female ,who had big bluish-purple eyes, straight and hip-length dark brown hair, and she wore blue female student uniform.

"Where am I and Who are you?" Kairi asked her.

"I'm Ran Mouri. Now you're at Beika park but why are you lying down on the bush?" Ran introduced herself.

Kairi tried to stood up from the bush but she felt down again.

"Let me help." Ran said then she helped Kairi.

After Kairi had finished cleaned herself from bush, ground from her clothes. She stood up and looked to Ran.

"My name is Kairi but what is Beika park?" Kairi asked Ran.

"So you're not Japanese people but how did you was unconscious on the bush?" Ran asked Kairi.

"I don't the last thing that I could remember was I was falling down from the sky and the light glowed on my body then I appeared at this park." Kairi explained about what she had remembered before met her.

"That is weird, I never hear about this before but where did you came from. I know that you came from foreign country. Maybe America" Ran asked.

"I came from..." Kairi stopped saying for a minute and thought something in her mind.

"What's wrong." Ran asked.

"I can't let her know that I came from another world but how." Kairi was thinking inside her head.

While Kairi was thinking something there was man in black suit stood up and looked down to them then he flicked his fingers.

Barrier was covered around the park and when we looked from outside we will see the park still the same.

Kairi and Ran stopped thinking then they looked around themselves. They saw many shadows had appeared from the ground and dark circle appeared around every area.

"Go hide somewhere! I take this." Kairi shouted and summoned her keyblade and ready for battle.

Ran didn't go to hide somewhere but she looked to keyblade then she stood in her fighting pose.

"Why are you here? It's too dangerous." Kairi asked her.

"I know but you must explain about that giant key and those black creature too and don't worry about me because I had fought them before." Ran said.

Kairi tried to let her went somewhere to hide but it couldn't stop her for helping so she and Ran stood in their battle stances.

"All right, let's do this." Kairi said then every shadows ran to her and Ran.

Kairi slashed first three shadows then she tried to shooting firaga magic from her keyblade but fire magic came out instead but it defeated heartless.

"What happen to my magic?" Kairi though but she saw 5 heartless jumped to her so she slashed them at the same time.

Ran dodged all of 5 shadow attacks then Ran defeated them by kicking them full power.

Kairi cast thunder, blizzard, fire then water to destroyed all of heartless then she used her 7 wishes and thrusted all of heartless 7 times.

Ran punched and kicked heartless but her attacks wasn't enough for defeating them so she fought them until all of them were defeated.

Both of them kept fighting until all of heartless was defeated and vanished.

After Kairi and Ran had defeated the last shadow heartless.

Kairi and Ran panted and both of them felt tired. They took a rest by sating on the nearest bench.

"What is that weapon that you used to defeated black creature?" Ran asked Kairi.

"This is keyblade it was my weapon that defeat heartless." Kairi explained and showed her keyblade.

"Heartless?" Ran doubted.

"Our enemies that was created from darkness but how did you know about them?" Kairi asked.

"There are rumors that dark creatures appeared every where in Tokyo especially in Beika city but this was the first time I saw someone managed to defeated them easily." Ran said.

"What do you mean?" Kairi asked.

"Not long ago there are a lot of mystery cases around here and police couldn't solve them like mystery robbery, mysterious dark yellow eyes appeared around city." Ran explained situation around here.

"So heartless had appeared before I arrived but why did you still walk around here even there were heartless appeared?" Kairi asked her.

"I just went to supermarket for buying ingredients then I saw warp hole then you fell down to the park. You fell too high so I ran as fast as I could until I saw you passed out and lied down on the bush." Ran explained how she met Kairi.

"But did the other saw that hole too?" Kairi asked and she felt nervous.

"No, Only me but why you don't want anyone know about this?" Ran asked.

"I don't want everyone know about keyblade or I came from another world." Kairi said.

"Wait what do you mean that you came from another world?" Ran asked Kairi.

"It's a long story but can I ask you that if you listen everything that I tell you, will you believe me?" Kairi asked Ran.

"I don't know but can you tell your stories during on our way because I have to buy ingredients for cooking dinner and breakfast tomorrow." Ran said.

"Sure I can." After Kairi had agreed with Ran, her stomach rumbled.

Kairi blushed while Ran was laughing then they started walking together.

Kairi told Ran about keyblade, heartless, other world and everything and she told her that she didn't know where to go first so Ran let her joined dinner with her family. Ran helped her a lot about Japanese language at the same time they had a lot of talk until they almost at Ran father working place.

On the way to Mouri Detective Agency.

Ran and Kairi were walking while Kairi carried one groceries bag and Ran carried two grocery bag.

"Kairi, why did you want to learn Karate even you can use your keyblade and fight those bad guys?" Ran asked Kairi.

"I know but when I was grabbed my wrist, I couldn't move my hand and I tried to escaped from him but I couldn't move my hand then he knocked me but when I know everything and Sora sacrificed himself for me and I couldn't do anything to help him or anyone else at that time." Kairi said sadly.

"That's why when you saw me fought black creatures you looked interested in me." Ran figured out why Kairi interested in her material arts.

"And that's not the only reason. Before I got my keyblade and power, I was kidnapped 2-3 times before I was kidnapped again." Kairi said.

"What! You were kidnapped." Ran shocked.

"Yeah but every time Sora came and rescue me but this time..." Kairi said and she made sad face and looked away from Ran.

"I know...I'm sorry about that." Ran apologized Kairi.

"It's okay but that's one of the reason I started my adventure. I wanted to be stronger I wanted to not made everyone helped me again because I was weak and useless but still I..." Kairi was explaining Ran but she stopped immediately when she thought about Sora.

"I know and I will help you." Ran said.

"Really...Thanks Ran." Kairi thanked Ran.

"But with one condition. What are you going to do while you're here?" Ran asked Kairi.

"I don't know maybe I might investigate about what happen at this world?" Kairi said with unconfident.

"You're the same age as me it's important to go to school and you didn't know Japanese language." Ran said.

"I know but don't worry. I had went to school in my island before but when master Yen Sid summoned me to became keyblade wielder and after that I traveled from my island to this world." Kairi told Ran that she had been to school before.

"That's good but Kairi did you know how long will you stay in this world?" Ran asked her.

"I don't know maybe until I solved this problem but there's a problem." Kairi said.

"What is your problem?" Ran asked.

"I don't know where to stay and I only have my money world left." Kairi said then she sighed loudly.

"Tonight you can stay at my place then we will discuss about this later." Ran said then they continued chatting about this town until they arrived at Mouri Detective Agency.

"Good evening, I'm Kairi. Nice to meet you." Kairi bowed and greeted A man and A boy but a man still confused what Kairi had greeted him because she spoke in English language but the boy stood up then he walked to Kairi.

"Kairi had been here to this town recently and she had lot of problem of language plus she didn't know where to stay tonight so I decided to brought her here for sleep with us tonight." Ran explained why Kairi came here and she decided to stay with us.

"Ran, I had a question why did you bring her here for staying tonight here?" Her father asked.

"I met her on the way to grocery store but she didn't know a lot about Japan and she didn't has a place to stay so I decided to help her by bringing her here then we will discuss later." Ran said.

"Does it okay for let her sleep here? She's a stranger that had arrived here." Kogoro asked and he worried about let her sleep here tonight.

"Don't worry me and Kairi had talked about this before we arrived." Ran said then she looked to the clock.

"You're good at English. Conan." Kairi admired Conan.

"Thanks but I have free time so I can help you tomorrow too. Can I go with you tomorrow?" Conan asked Kairi.

"Sure, no problem it's good to have someone good at English but what about?" Kairi asked Conan.

"Don't worry about me but did you have any money?" Kogoro asked Kairi.

"No, But I'm sure I will manage somehow." Kairi said then Ran walked out from Kitchen. She wore apron and her clothes.

"Food is ready. Sorry for making all of you so long." Ran apologized for making everyone waited for food.

"It's okay Ran-neechan. What did you cook for dinner?" Conan asked Ran.

"Today I cooked Hamburger Steak." Ran said then Ran brought everyone dinner and put them on Japanese table.

"It looks delicious." Kairi said while she was looking to her Hamburger Steak.

"Let's eat before it get cold." Ran said then she sat on the floor around Japanese table.

Everyone enjoyed their dinner then they had a little talk and watched news together. Time passed until Kairi was left alone at dining room.

Dining room (After Everyone had left.)

Kairi was sitting on the floor and looked to the card that man of light had given to her.

"How did I use this?" Kairi thought for a while then Ran entered and she carried Ran pajamas that she didn't wear them.

"What are you doing?" Ran asked Kairi.

"I was thinking why he gave this to me?" Kairi said while she was looking to her card.

"Who?" Ran asked Kairi.

"He called himself man of light. He told me that card will help me during the journey." Kairi said then she picked the rest of his cards.

"What are these cards? I have never seen them before." Ran said.

"If I manage to find out or know how to use them. I won't have any problem during my journey." Kairi sighed sadly.

"Maybe they need some word to activate." Ran suggested.

"Some word..." Kairi said then she tried to remembered what man of light had told her.

"If you want to use those cards you only need to say get while you're holding one of those cards."

"Holding one cards." Kairi said then she chose a card that had a picture of wallet and put the other two down on Japanese table.

"Get" Kairi spoke then something happened that pink wallet appeared in front her.

"Woah!" Ran and Kairi exclaimed together.

Kairi opened her wallet then she saw her pocket money with mini notes inside. Ran and Kairi looked to the note.

"This is your pocket money that would be enough for the first world that you visit now but if you want more. I suggest that you need to find part-time job in this world."

"So he had given you a money and it can be used in this world now you don't have to worry about that problem anymore." Ran said.

"Yeah, Now what about the other..." Kairi said then she picked the other two cards.

While she and Ran were talking and checking cards. Conan was peeking behind the door quietly and he thought something.
