A young girl of about fifteen walked down a sunny beach.  As she stopped to admire the beautiful, crashing waves of the ocean, a warm wind blew through her auburn hair.  Her eyes took on a faraway look as she began to remember distant memories.  They took form in the shape of a young boy with brown hair, searing blue eyes, and a strong heart. 

"Sora…", she whispered, "…you promised."  "You promised to come ba ¾ 'HEADS UP!!', someone yelled interrupting her thoughts. 

"Wha…?" the girl turned around just in time to catch a blitzball with a forehead.  She stumbled and fell to the sand. 

"Kairi, are you all right?" A boy stood over Kairi with a concerned look on his face. 

"What do you think Wakka?", Kairi asked. 

"Hey it's not my fault, man," Wakka countered, "I said 'heads up'." 

"HEY WAKKA, HURRY UP WILLYA!?", a voice called out.

"IN A MINUTE, TIDUS!" Wakka turned back to his friend.  "Are you sure you're okay, man?" 

Kairi looked up at Wakka and smiled.  "I'll be fine, it's probably just a mild concussion but I'll walk it off."  Wakka grinned and ran back to join Tidus. 

Kairi shook her head and turned to follow Wakka when something caught her eye.  Curious, she walked down the beach to see what was shining in the sand.  She discovered that the glare was the sun reflecting off of a glass bottle with a key chain wrapped around it.  She also noticed that there was a bit of paper inside of the glass bottle.  The rest of the bottle and chain were half buried in the dug so she dug it out. 

Kairi looked at the end of the key chain and gasped when she recognized the ornament attached to it.  To any other person, it was a simple, metal flower.  To Kairi, it was the symbol of everything she and Sora had together.  It was the good luck charm she gave to him back in the other world.  "The paper must be a message from Sora!" she realized.  She looked around for something to get the paper out but, finding nothing, she smashed the bottle open with a rock.  There, on the hot sand, she began to eagerly read the message.

Kairi,

I send this letter to you with the confidence that it will reach you.  Even though we're worlds apart, out hearts will be connected forever.  I made two promises to you in the past Kairi, one was to return your good luck charm, and the other was to return to you someday.  I've fulfilled one but I don't know if I can fulfill the other.  I've found Riku and he's doing fine.  He's frustrated with himself for being taken by Ansem and punishes himself day in and day out.  You know Riku.  We have spent so long trying to find the door out of Kingdom Hearts but we're running out of time.  The heartless are getting stronger while we are getting weaker.  Riku is starting to lose hope and I don't blame him.  The only thing keeping me from losing faith is the hope that I'll see you again.  Take care.

Sora

Kairi read the letter again and again until her tears blurred it out of sight.  The ache in her heart was so deep that she couldn't breathe.  Her tears dropped on the good luck charm and it began to glow, but Kairi didn't notice.  She began wiping the tears away and screamed to the unanswering sky. 

"I'm a princess of heart, my heart is the one of the purest lights there is!  There has to be something I can do to bring them back!" 

She put the letter in her pocket and was about to do the same with the charm when she saw it glowing.  She gasped as the ornament began to vibrate and transform.  The light got so bright that she covered her eyes and when she lowered her hand, she saw it.  A keyblade…one of the weapons that had been able to take Sora to other worlds.  Could it take her to Sora too?  Kairi knew what she had to do.  She remembered talking with Sora about the keyblade and how heartless are always trying to destroy its master.  If she was going to find Sora, she would need to train.  She began to walk towards Tidus and Wakka.
