Once upon a time, in a land far away, a little village was troubled by a wicked fairy.
This devilish sprite delighted in causing strife to the innocent people of the village. He would spook the cows off of the paths and eat up the entire apple crop in one night. But he grew bored with this simple mischief after a time. He decided he wanted to do something so wicked that no one would ever forget it.
There was a boy named Light who was walking along by the river one day when the fairy decided to do its wicked dead. The boy saw a sword of black metal lying on the riverbank, shining in the sunlight. He called out to see if he could find the owner of the mysterious weapon, but no one answered.
The boy picked up the sword. The sword was not heavy, but it felt very cold in his hand. Moved by his curiosity, the boy swung the sword around a few times. It felt very good in the air. He knew he should put the sword back because it wasn't his, but something deep inside of him compelled him to keep it.
As the boy was walking home he hid the sword under his clothes because he did not want to share his secret with anyone else. Unfortunately a boy walking alone so late at night is an ideal target for bandits. Three of them set upon the boy named Light by the side of the road a few miles from the village.
"We are Gron and Dak and Bol. We are going to kill you, boy, but first tell us what you are hiding under your shirt. If it is valuable we may let you live." Said the bandits.
The boy was very afraid but when he felt the cold metal of the sword against his skin he could not give it up. Something forced him to keep his fingers clasped around the hilt as he drew it out. The bandits were awed by the beauty of the swords black metal but when they reached out to take it the boy would not let go.
Suddenly in a flash the boy sprang at them, holding the sword like an expert. The bandits ran before the boy but he cut them down like blades of grass. The boy was even more afraid now because he had never even held a sword before in his life and certainly did not know how to use one. But he did not put the sword back even though it was stained with the bandit's blood. He cleaned off its smooth black surface and marveled in the beauty of it. So entranced was he that he did not even notice the fairy until he spoke.
"I see you have used my sword." The boy screamed at the sight of the fairy because he seldom revealed his gruesome visage and it was a horrifying sight. Only now did the boy feel ashamed for taking something that wasn't his and he thought about giving it back to the fairy so he would go away. Only when he picked up the sword to return it to the fairy the cool feel of the metal was too lovely to give away.
"Is it a magic sword?" The boy named Light said, for he was curious. The fairy looked into the boy's big bright eyes and decided that this beautiful child would be the one to be his entertainment.
"Yes, this is a magic sword. If you use it you will be able to kill any man with it, as long as you know his name. What is your name boy?" The fairy said.
"My name is Light." Said the boy. The fairy thought this was the perfect name for the one to wield his dark sword.
"Then this sword is yours now, Light." And the boy's face lit up with joy.
The boy went home to his family that night as usual, keeping his treasure hidden. But every night he would sneak out of the house to fight the criminals and lowlifes that preyed on travelers. He even began to challenge nobles and rulers to do battle with him, freeing peasants from their clutches but taking the land for his own. No one knew what to call this mysterious dark night who could kill whomever he pleased so they called him Kira.
As the boy named Light grew to be a man, his lust for power grew as well. He dreamed of conquering the entire kingdom and ruling with mercy and justice. But he was corrupted by his murders and his once bright soul slowly rotted as he held the fairy's sword.
But there was no one who could stop him as his conquest slowly turned to a rein of terror.
