I only own my OC.

Prologue- Birth by Sleep

World- Radiant Garden

Time- Ten years before Kingdom Hearts.

A little boy sat on white steps that led up to a towering castle. His name was Seiya and he had just turned eight. He had short messy black hair, tanned skin from being outside all the time, and bright green eyes. He was wearing a white T-shirt, black shorts with a leather belt and black boots. Latched onto the belt was a two foot long wooden sword.

He had a very important job… he was supposed to protect the princess from bad people and otherwise keep her company! He watched as the little red haired girl picked flowers in the garden in her little white dress. He was going to grow up and be a big strong knight like Zack and Squall one day and this was his first mission.

"Seiya!" The little red head called to him while waving.

"What's wrong Kaiwi?" He replied.

Unfortunately he had not grown out of baby-talk yet and still sometimes pronounced 'r' like 'w' which really annoyed him but amused everyone else.

"Come look what I found!" Kairi replied happily.

Smiling Seiya hopped to his feet and walked over to the smiling little four year old. When he got there she grabbed hold of his hand and pulled him over to a little patch of Daffodils and pointed.

"Look! I found a puppy!" She said pointing.

Sitting in the Daffodils was a tiny Jack Russell puppy… it was barely bigger than Seiya's hand and was white with a light brown patch over its right eye and floppy black ears. Around its neck was a green collar. Looking up at them it yawned before curling up on the ground.

"Aw its so cute! Can I keep it?" Kairi asked hopefully as she picked it up and hugged it gently.

"It has a collaw Kaiwi. We need to give it back to its Owner." Seiya told her.

For a second Seiya thought Kairi was about to cry but instead she just sniffed and nodded. Just then they heard a womans voice.

"Chomper! Chomper! Are you here?" The voice shouted.

Seiya and Kairi turned and saw a middle-aged woman wearing a yellow sun dress that had black hair and grey eyes looking at them. Smiling when she saw the little puppy dozing in Kairi's arms she walked over.

"Chomper!" She said happily "Thank you for finding him!"

Kairi reluctantly handed the little puppy over to the woman but seemed to be holding back tears as she did so.

"Thank you again for finding him!" The woman said "As a reward you can play with him when I bring him to the park."

"Really!" Kairi asked hopefully.

"Of course. I'm sure Chomper would love to play with you." The woman replied.

"Yay!" Kairi cheered as the woman walked away.

Seiya smiled before taking a seat in a patch of grass and lay back looking up at the clear blue sky. His thoughts wandered to what exactly Master Ansem was researching now and if he would let him help again like he did last time. He had been researching Synthesis and had heard that Seiya had lots and lots of rare materials. He had helped Ansem make a cool weapon that looked like a really, really big key. He wasn't allowed to keep it because when Ansem tried to pick it up to give it to him it vanished in a burst of light. Afterwards Master Ansem had a thoughtful look on his face, thanked him for his assistance and left.

That had been three months ago and when he had gone to see him with Kairi last month he had happily asked Ansem if he needed anymore of his material. Ansem had smiled and told him that he was done researching Synthesis and was trying to figure out what the weapon he had made was.

Suddenly he heard Kairi scream and leapt to his feet. Kairi was surrounded by six sleek, humanoid creatures with blue skin there arms and legs ended in points and had no distinct fingers, they had a triangular head with two long, jagged, lightning bolt-shaped antennae, their red eyes were set in an angry expression and they were moveing in a jerking, twitchy motion.

"Kairi!" Seiya shouted as he pulled out his wooden sword and dashed into the circling creatures.

He grabbed her hand and looked around for an exit before pulling her along, running between a pair of the odd monsters and down the street towards the castle. He dared not turn and look to see if the monsters were chasing them but he knew that they were. As they reached the stairs leading up to a circular landing that was the castle entrance he felt something cut into his arm. Shouting in pain he pushed Kairi forward before turning to face the monsters.

"Wun Kairi! Get to the castle!" He shouted at her.

She didn't move for a second before turning and running up the stairs. The all but one of the monsters sand into the ground to become something like black puddles and rushed past him. He hopped around in a sort of jig to avoid them before realizing the last monster rushed at him. Gripping his wooden sword tightly he slashed at the leaping monster… and surprisingly managed to bisect it. Instead of the two pieces landing in a heap they seemed to burst into black flames before vanishing. Seiya heard Kairi scream again and ran up the stairs. Just as he reached the top he heard a womans voice.

"No! Run!" The woman shouted.

Seiya reached the top of the stairs in time to see a blue haired girl holding a weapon similar to the one he had made move Kairi behind her.

"Kairi!" He shouted as he ran up beside the woman and held his wooden sword in front of him "Go away you monsters!"

"No! You need to get away from here!" The woman told him.

"NO! I'm staying to pwotect my fweind!" He replied bravely.

Just then one of the monsters leapt at them only to be destroyed when… a short human-like mouse destroyed it with another weapon like the one he made and the one the woman had.

"Hurry" The mouse said in a high-pitched voice "You gotta get those two to someplace that's safe!"

"Who are you? Why do you have a Keyblade?" the woman asked in confusion.

"I'll tell ya later! Right now we gotta stop these things!" The mouse said.

The woman nodded and scooped down to pick the two kids up only to find the little boy wasn't there. She looked around in a panic before seeing that he had charged forward yelling with his toy sword raised to strike. She quickly rushed forward and scooped him up under her arm before turning and dashing off.

"HEY! PUT ME DOWN! I WANNA HELP FIGHT THE MONSTEWS!" Seiya shouted as he struggled to get away from the woman.

She set the two of them down at the bottom of a different set of stairs in an open courtyard before putting a hand to stop Seiya from dashing back up the stairs.

"You need to stay and protect your little friend!" The woman said before dashing up the stairs.

Seiya briefly looked sad before turning to check on Kairi. The little four year old had watery eyes but wasn't crying after checking to see if she was hurt but finding nothing he knelt down and looked her in the eyes.

"Awe you okay Kairi?" He asked.

The girl nodded before latching onto his neck and sobbing.

"I was so scared Seiya!" She said.

A few minutes later and the woman and mouse came down the stairs to check on them. Seiya ran between them and Kairi with his sword raised.

"Who are you!" He shouted.

The woman kneeled in front of him and lowered his wooden sword before smiling reassuringly.

"My name is Aqua and I'm a friend." She said soothingly "Is your friend okay?"

"Yeah she is." Seiya said gruffly.

He didn't stop looking at her face with what he hoped was a tough expression… but on an eight year old it only came off as cute.

"Well I'm glad your ok." Aqua said happily.

"This girl is special! We should join forces to protect her!" The mouse suggested.

"Hey its my job to protect Kairi!" Seiya said angrily.

Before they could respond the mouse disappeared in a burst of light and shot off into the sky. The three of them stared at the retreating ball of light for a few seconds before Kairi spoke.

"Here." Kairi said handing the flowers she had picked to Aqua.

Aqua turned to face Kairi and smiled.

"Are these for me?" She asked.

"I picked some flowers. Thank you for saving us." Kairi said.

"Hey I saved you too." Seiya said sadly.

"I know!" Kairi said before hugging Seiya.

Seiya turned and looked at Aqua for a few seconds before smiling widely.

"Your pwetty and very stwong Aqua! Will you be my girlfriend?" he asked.

Aqua looked surprised for a second before smiling and giggling at him.

"Maybe when your older." She replied before rubbing his hair.

She took the two of them to a safe place… and then left.

World-Radiant Garden

Time-One Year later.

Seiya ran through the street trying to escape the mass of little shadow monsters chasing him. For some reason the world was dissolving into shadows and he didn't know what to do. Just as he was about to reach the castle the ground underneath him disappeared… and he fell into darkness.
