What the book is about

The novels revolve around “shigofumi,” letters that the dead sometimes manage to send to the living. Special messengers deliver them, and each episode typically explores the recipient’s connection to the deceased—regrets, guilt, unresolved promises, and the consequences that spill into the lives of those left behind.

How closely the anime matches the book

The anime keeps the core premise (a courier delivering letters from the departed and case-by-case stories), but it is not a strict, volume-faithful adaptation: some stories are rearranged or changed, and additional original material is used to shape a continuous TV narrative.
