RYUK SPOILER!
RY
Ryuk is the Shinigami who drops his Death Note into the human world because the Shinigami realm has become unbearably boring. Light's decision to use the notebook on a massive scale gives Ryuk exactly the entertainment he wanted. He explains the notebook's rules, develops an obsession with apples and follows Light almost everywhere, but repeatedly reminds him that they are not partners. Ryuk is not interested in justice, Kira's new world or L's investigation. He is interested in seeing what humans do when given power they were never meant to have. That detachment makes him funny and unsettling at the same time. From the beginning, Ryuk also warns Light that when everything ends, he will be the one who writes Light's name in his own Death Note.

RULES OF THE NOTEBOOK //
Open page →Touching a Death Note Reveals Its Shinigami
Open →Contact Is Enough · Ownership Is Not Required
A human does not have to own a Death Note to see and hear the Shinigami attached to it. Physical contact with the notebook is enough, and contact with a piece of Death Note paper can carry the same supernatural connection.
Why it matters
Notebook fragments are more than hidden weapons. Contact can expose the supernatural side of the case to someone who has never owned the book, and later the same contact rule becomes central to The Helicopter Memory Recovery & Higuchi's Death.
