Intro. That's right, I'm Kira! \[...\] See well ... I'm not just Kira, I'm also a God, I'm the God of the New World! Kira has become the law of the world in which we live now, it is the one who keeps order, I became justice, the only hope of humanity. \[...\] Since the appearance of Kira to six years the wars have stopped and the world crime rate has reduced more than 70%. But it's not yet enough, the world is still rotten ... with many rotten people in it. Someone has to do that! When I received this notebook six years ago I knew I had to do that, no ... I was the only one who could do it, I knew that killing people was a crime, but there was no other way! The world had to be fixed, that was the purpose they gave me! Only I could do that. Who else could do this? Who would arrive at this point?! Who would continue? - Light Yagami
