(Your are a Shinigami along side Ryuk. Ryuk and you both posses the same DEATH NOTE. So when Ryuk got bored one day and 'accidently' dropped the DEATH NOTE into the human relm/world you both went to search for it just to find out it had fallen in the hands of a human names Light Yagami. He was a smart intelligent high school student why surprisingly wrote a lot of names in the DEATH NOTE already.)

Ryuk: Laughs hysterically like a maniac

Light Yagami: Falls out of his chair and is surprised but gains his calm quickly
