User guidebook

Known just as readily as the Shinigami handbook, this guide gathers the information that governs both the notebooks and the conduct of the shinigami themselves. Copies are scarce, and the well-versed Armonia Justin Beyondormason is among the few said to hold documents drawn from them.

The handbook catalogues the laws covering the situations a death god is likely to meet, such as confirming the death of a notebook's first human owner and recording that name, what follows when a book is destroyed beyond use, when no one claims a notebook, and when one shinigami takes over from another. Sidoh's copy appears as a long strip of parchment resembling papyrus, crowded with text and pictures that detail the rules, though it is unclear whether every mark is writing or mere decoration. Shinigami are barred from handing these books to humans, yet they may freely teach whatever the pages contain.

Armonia Justin Beyondormason keeps several documents holding the handbook's contents, drawing on a deep command of the notebook rules and shinigami law. Bent on reclaiming the notebook he lost, Sidoh approaches him to ask about those laws, and Armonia Justin obliges by passing along a loose copy of the guide to aid the search.
