The world that Yagami would have created, would be a world of peace. But peace under the threat of death is not truly the kind of peace that Light was seeking. Light sought a world where murder, rape, theft, and many horrendous crimes were not committed at all. He knew however that with the muck the world had come to and gotten itself stuck it, someone would have to give a mighty shove to get it unstuck.

Light...or rather Kira's actions had far reaching effects. The Kira names were never released. It was given out that Kira had died shortly after his idenity had been discovered. The world could rest in peace.

Despite the cringes of some police officers, that figured this would mean more work. To the world's delight it did not mean as such. People were truly moved from their fear. During the five years of being under constant threat of dieing if they ever committed a crime.

People began to care a little more. A cat gets stuck in a tree, and the people walking by would climb up to help get it out. A car wrecks, and your normal average citizen would jump into the wreckage to pull out the driver.

It was just this overall amount of little things that the world began to do. Those of the faith began to seriously pray and be thankful. Those of the cloth began to leave little boys alone, and let them sing in the choir rather than sing in the shower...with them. Those of the law, began to stop trying to sucker every little person into sueing for some stupid and ridiculous reason.

Yagami Light, Misa, that...Takeda girl...and the crazy one that kept saying 'excute'. Each of them had their reasons, and each died a rather horrible death. The crazy one bled to death after he stabbed himself so Light could escape. Misa offed herself. The Takeda girl offed herself as well. And Light ended up going away as well.

Each of them found their brand of peace in the after-life. In a vast nothingingness where they played games and had a merry old time despite much of who they had been in life. Light found himself in a nice threesome relationship, even if his two girlfriends argued a lot.

That crazy dude even found a girl...though by girl I literally mean a little girl who'd used it to kill her teacher. He became something very akin to a father to her. Course he was given lessons on not saying 'excute' around her all the time.

The world would go on for as long as we can see into the flow of time. Despite the violent ways of going about it, Yagami Light had brought about that peaceful age he had sought. To some, he truly was a god.
