A Prism of Light and Darkness

I. Twilight Town: Opposite siblings, connected by a key 1

"Vanitas," a long silver, messy hair girl started as she sat in a train compartment. She wore a thin black and white dress with a white open jacket over it along with a pair of white cork shoes. "What was our home like again?"

Sitting across from her was a black, spikey hair boy wearing a black long sleeve T-shirt with a short sleeve dark gray open sweatshirt over it along with a pair of black colored jeans and a pair of black shoes.

"I've told you about it a hundred times, Raiji." The boy, Vanitas, said as he looked towards the silver hair girl with an annoyed look on his face. "You should remember all the fine details that I told you about it."

"I do," the girl, Raiji, said with a pout as she crossed her arms over chest, "but I really like it when you tell me!"

"Despite that you don't have any memories of it." Vanitas said with a smirk.

"I can't help that I lost all my memories of home!" Raiji exclaimed in her defense, "But I am trying to get them back."

"…Just don't rush it, okay?" Vanitas said after a moment of silence between as the train they were on slowed down some. "There is a lot of stuff to remember but there's also plenty of time for it to come back. So be patient and let it come to you naturally, all right?"

"All right," Raiji said with a sigh as she looked down at the ground. "Could you still tell me?"

Vanitas stared at the silver hair girl for a moment or two before letting out a sigh. "Fine," Vanitas said, causing Raiji's face to brighten, "but I'm only going to tell you your favorite place to hide from everyone!" Raiji merely nodded her head vigorously as the train pulled to a stop. "Alright," Vanitas started as he got up from his seat and walked towards the doors, "there was this place called the "Fountain Court" where it was nothing but fountains and walkways. You loved it there since hardly anyone bothered to come get you since it was rather difficult to come and go through there."

"Really now?" Raiji said sounding somewhat impressed, "So even back then I liked my solitude from the world."

"Yeah, but that was before they started sending me in to get you." Vanitas said as he walked out of the train station in Twilight Town. "After that, you would do everything in your power to make sure that I couldn't get to you, even pick a sword fight with me despite that you lost every time."

"I still do, don't I?" Raiji said sounding annoyed slightly.

"Yeah, but you would also challenge me to a magic fight from time to time and totally wipe the floor with me like you do now." Vanitas said as he turned to look at Raiji who stood on the steps of the station. "Though it took you some time to remember all your spells after coming here and losing your memory, right, little sister?"

"How many times do I have to tell you, I'm not little anymore Vanitas?!" Raiji exclaimed as she stomped her foot on the ground.

"Hello Raiji," a high pitched voice said, catching Raiji's and Vanitas's attention. They both turned their heads towards the direction where the voice came from to find a little creature with a yellow hat with a face on it walking towards them.

"Hey Vivi," Raiji said with a smile as she climbed down the last steps, "did Seifer and the others make you come and get me?"

"They did but I don't mind." The creature, Vivi, said as he looked up at Raiji with his big yellow eyes. "Ready to go?"

"Just about," Raiji said with a smile as she turned her head towards Vanitas. "May I?"

"…Fine, but be here before the last train comes, alright?" Vanitas said as he stared at Raiji with his blue colored eyes.

"I will," Raiji said with a smile as her aqua/teal blue colored eyes showed a slight glint in them. "Let's get going Vivi."

Vivi merely nodded his head as he and Raiji walked off together.

"Even now, she likes her moments with the outside world a little bit more than the moments in her world." Vanitas muttered under his breath as he stared after the duo as they disappeared from sight.

"I can't get her out of my head." A silver hair boy muttered under his breath as he leaned against a crooked shape tree with star shape fruit on it.

"Get who out of your head?" a cheerful sounding voice asked, causing the silver hair boy to jump slightly.

The silver hair boy quickly turned his head around to see a brown spikey hair boy walking towards him with a smile on his face.

"No one that you know, Sora." The silver hair boy said cockily as the spikey hair boy sat on the tree next to him.

"Come on, Riku," the spikey hair boy, Sora, whined slightly, "tell me, who is she?"

"…I really don't know," the silver hair boy, Riku, said after a moment of silence. "I've only ever seen her in my dreams, yet…I don't think I ever met her in real life though."

"Hmm…" Sora said as he crossed his arms over his chest in thought, "How about we visit Leon and the gang? Maybe they'll know a thing or two about your dreams?"

"Maybe…" Riku said as he stared out into the ocean.

Sorry if the characters seem out of character, it's been awhile since I last wrote a fan fiction for Kingdom Hearts. By the way, Vanitas is not Vanitas from Birth by Sleep. It's a different character that I decided to name Vanitas as well. Edit: I changed it, enjoy
