The Act of 1863, allowed slave trade in Japan. The Act was never removed, and did not allow any Japan citizens to be captured as slaves. Japan is the only known country to still have slaves, in the year 2000 and after.
The reason the Act was put into law was because America and England were once allies. The staged an attack on Japan back in the 1800's. It killed hundreds of innocent Japan citizens. For the longest time, the war that followed put Japan in debt.
Because there was English and American citizens in Japan after the war, the government decided to put the law in action, to inslave those citizens to help work so that they could pay off the debt. They inslaved those citizens, then let the actual Japan citizens buy them.
The money they used went to the government, and in the year 1952, the debt was payed off. The government went into debate on whether or not to keep the law or abolish it. The profits of the slave-trade was very value able, so the law was never taken out.
That's were this story begins.
L my have been the World's Greatest Detective, and many times help Japan with cases there own detectives could not solve, but they still turned on him.
It all started with the Kira case. Light Yagami was the prime suspect. L had worked side-by-side with him, and when it was proven that it was Amane all along, Light was set free.
Unknown to the Task Force, L was hot on Light's trail, he almost proved that Light was Kira, and Light asked Misa secretly to take the fall for him, and that she would be avenged. For he knew where L was born, thank that one night.
Light was set free from the handcuffs, and to celebrate, Light's father was going to take Light out drinking, [the law of 1923 let under aged citizens drink as long as they had a license that their parents signed to let them.] and Light had asked if L could go along. He said that L was his 'friend' and that he wanted him to come along.
L didn't like to drink, you let things slip when you did, but went along with Light since Light was L's first friend. L didn't plan on drinking, he just went along because Light's father was busy, and he planned on driving Light back to the Head Quarters, and to make sure Light didn't get into any trouble while drinking.
Light, once there, some how convinced L to drink with him. L was a light drinker, that's all there is to it. It didn't take long for him to get drunk,and they got into a conversation of there past. Light got L to admit that he was from England.
L never did admit that he was an illegal citizen, he didn't have to. No one knew L's real name, so there was no way that he was really a legal citizen. Light, figured this out days after their outing.
So when Misa admitted that she was Kira all along, the case was solved, and Light asked L to speak with him one last time, since there was a chance that they would never see each other again.
Of course that was a trap, Light had told his father everything, and that they were force to capture L. So when L walked into the room, they Task Force pulled their guns on him and he was arrested.
But that same day, Mr. Yagami realized that Light's birthday was coming up, and thought that Light was heart broken to have to have his friend arrested and then later bought. He could tell by Light's face.
So, instead of having L arrested and taken to jail where he would be put through a series of test and later sold at the black market, or slave trade, he decided to buy L before anyone else could have the chance to.
But of course, he had to give L to Light early since it would be hard to hide L in their house without Light knowing.
And Light was, to say the very least, happy. His plan had worked, and now, he would have L, to have his enemy finally bow down to him.
L was taken to the Yagami home that evening. His life as he knew it would change forever.
