RY

Death Note · Shinigami / Chaotic Observer

A death god who deliberately discards his lethal notebook into the human realm out of pure, unadulterated boredom with the stagnant realm of the dead. He refuses to take a definitive side in the psychological war between Light and L, choosing instead to operate as a completely neutral, apple obsessed spectator. His presence is a constant reminder of the cosmic indifference underlying the entire high stakes human drama, finding entertainment purely in the lengths to which human ambition will stretch.

The Notebook Light Finds Belongs to Sidoh, Not Ryuk

Stolen by Ryuk · Dropped for a Human to Find

The first Death Note Light picks up is not Ryuk's personal notebook. Ryuk stole it from another Shinigami, Sidoh, then dropped it into the human world because he was bored. Ryuk remains beside Light because he is the Shinigami attached to the notebook in human hands, but the physical book itself began as Sidoh's.
Why it matters
The story's first notebook already has a history Light does not know. Years later, its original owner comes looking for it, turning an object Light treats as his weapon into someone else's missing property.

Light Rearranges the Notebooks Before He Gives Up His Memories

Ownership Is Part of the Plan, Not Bookkeeping

Before surrendering his Kira memories, Light does not simply abandon a notebook and hope for the best. He rearranges which Shinigami is attached to which notebook and prepares the chain of possession that will keep Kira active after he no longer remembers being Kira.
Why it matters
Ownership Relinquishment & Memory Erasure only works as strategy because Light plans the notebook's future before removing his own knowledge of the plan. The object keeps moving even after the planner disappears from his own mind.
