Ryuk

The Shinigami who owns the Death Note that Light Yagami picked up. Out of boredom, he dropped the notebook into the human world and attached himself to Light, the notebook's first owner, enjoying merely observing all of Light's actions without doing anything himself. He stands as a mere observer of Light's actions, neither on Light's side nor L's side. Additionally, he explains to Light that his obsession with apples is similar to human addiction to cigarettes or alcohol, and from his eccentric behavior in the story, it is believed that he has withdrawal symptoms for apples.
