Revival

Taken into custody as the suspected mass murderer, Higuchi is fitted with a helmet rig so the detective can question him directly. Pressed on his method, the captive confesses to owning a notebook that kills, fully aware of how absurd it sounds. Soichiro recovers the book from the vehicle, and the moment he holds it the towering figure of Rem appears before him, with Mogi soon sharing the same unsettling sight.

When the detective handles the notebook himself, the existence of death gods becomes undeniable, and he silently recalls every earlier reference to such an object, including a meeting between two Kiras in Aoyama on the very day Misa first crossed paths with Light. He concludes a second notebook must exist. Light then lifts the book from the detective's grasp, and the contact floods back every memory of his original campaign.

The full design surfaces: the notebook Higuchi wielded had always been Light's, arranged so that Rem held ownership while Light surrendered Misa's during his confinement, which let his recollections return on contact. Before parting with the book, Light had Ryuk inscribe two counterfeit clauses, one demanding the owner write every thirteen days or die, the other threatening death to anyone who handled a book destroyed by fire or shredding.

Light executes Higuchi using a fragment of the notebook concealed in his watch, feigning frustration at losing a witness while privately turning his aim toward the detective. Studying the rules, the team finds itself trapped, since the burning clause appears to vindicate both Light and Misa. The detective alone senses the specifics are too convenient and asks Rem whether all such notebooks are identical and whether others remain; she answers vaguely, protecting Misa without quite lying.

Cleared in the eyes of the others, Light and Misa are released, and he chooses to keep investigating without his restraints. He directs Misa to dig up a second notebook he had hidden away months earlier. At the burial site her own memories return, though a slip meant to record the detective's real name stays blank, another piece of Light's plan. Reunited with Ryuk, Misa strikes a fresh bargain for the eyes to uncover the detective's identity, again halving her lifespan, while the detective begins quietly setting his own counterstroke.

This chapter restores Light's identity as the founding Kira and locks the investigation into the forged thirteen-day rule, the trap that paralyzes any attempt to dispose of the notebook. Misa's renewed deal with Ryuk costs her half her remaining years a second time, a sacrifice Rem witnesses through a security feed. The episode ends with both schemers, detective and killer, moving toward open confrontation.
