Light Yagami sat at his desk, his lamp on not studying. Or at least not in the conventional sense anyway. He was studying the mess he was in, with L and Misa and the poliçe and the Death Note. God, he had made such a mess. A side of him that resembled common sense was appealed at the mess he made.
The more dominant side of him was thrilled with it. This was the way to clean the World. He was going to bring down the order and those who hid behind it then build another one. He would do this because he is tired and bored. Bored of this world, tired of where it was going.
And he had a companion with him who was there for every step of the way, who saw everything he did. Someone who was just as bored and tired as him. He turned his head to the side to see the Shinigami who was chained to him until he or the Death Note was finished.
The creature that heralded death was howering next to him gleefully eating apples and watching him. At the moment he looked more like a child than a death god. Yet this creature was also murderous, selfish and arrogant. It was like looking at one of those funny mirrors at a fair.
Ryuk had went and "dropped" a Death Note ,the most dangerous mass destruction weapon in history, to the Human World simply because he was bored and came looking for it five whole days later. And yet, he did that because he was so sick and tired of his own rotten World.
He would never admit it out loud but he was just a tiny bit happy that Ryuk was there. The Shinigami was the sole witness of his hard work, his superior intelligence and god complex. One so much like him too. If he wasn't a Shinigami Light might have even believe that Ryuk was his long lost brother.
For now he would just settle on him as his Shinigami counterpart, in many ways, and keep being a tiny bit happy that even now so deep in this he had someone with him every step of the way.
