Six Death Notes

The Six Death Notes are a cluster of notebooks at the heart of Death Note: Light Up the NEW World and its novelization. Because the rules permit only six active books among the living at once, six shinigami deliver six notebooks to six separate owners, and the film becomes a contest to seize every last one.

In Light Up the NEW World, the rules permit only six Death Notes to be active among the living at any moment. The Shinigami King dangles his own throne as the prize for whoever turns up a new Kira, so six death gods carry six of the books down to be claimed by six different people.

The opening owners and their attached shinigami are Alexey Ivanov with Sidoh, Sakura Aoi with Bepo, Hikari Yagami with Ryuk, Ryuzaki with Arma, Roger Irving with an unnamed shinigami, and Kenichi Mikuriya with one called Eve. One of the books is the very notebook Light and Misa once used, brought back by Ryuk for Light's son Hikari.

Two forces race to gather the Six Death Notes: Yuki Shien, who would lock the books to Kira's cause if he held the full set, and the Japanese Task Force, who could seal them away to stop anyone else from killing. Shien runs down most of them and feeds them to Mishima, and once Mishima is taken the whole batch lands with the Task Force.

As the Task Force moves the notebooks to safety, the unit is ambushed, leaving some of the Six Death Notes destroyed while at least one survives and returns to use as fresh heart-attack deaths begin. Which of the books were lost is never revealed.
