Gelus's Death Note

Marked with the characters arvc-5 in white across its black cover and filled with the usual ruled pages, the notebook owes its existence to a god of death's sacrifice. Gelus, smitten with Misa, used it to strike down the man fated to murder her, an act that cost the shinigami his own life and left the book behind. Rem reclaimed it, carried it into the human world, and delivered it to Misa, the woman she believed was destined to wield it.

When the Task Force detains Misa as a suspected second Kira, she signs the book over to Light and loses every memory of using it, after which Light swaps the gods of death so that Ryuk stays bound to the book through the rest of the series. Light buries it while Misa is held, then later sends her to dig it up, recover both the book and her memories, and strike the eye bargain with Ryuk; for the next five years she kills on his instructions. The label arvc-5 nods to a hereditary heart disorder that can trigger sudden cardiac death.

Following the time skip, Light persuades Misa to give it up again under the guise of wanting an ordinary wife and hands it to Mikami, who takes up the role of Kira during Light's exposure. Mikami feeds names to Kiyomi Takada and locks the genuine book in a bank deposit box while flaunting a fake in public, until Gevanni recovers the real one and Near burns it, ending its time in the human world. Across that journey the notebook passes through Gelus, Rem, Misa, Light, Mikami, and Takada.
