Light regains his memories and uses the Death Note to kill Higuchi, regaining possession of the book. After restoring Misa's memories, Light instructs her to begin killing as Kira, causing L to cast suspicion on Misa. With Light insinuating the investigation would lead to Misa's capture and execution, Rem realizes Light's plan all along was to have her sacrifice herself to kill L, as a shinigami may not kill others to prevent a human's death. After Rem kills L, she disintegrates and Light obtains her Death Note. The task force does not announce L's death and agrees to have Light operate as the new L. With Light working as both L and Kira, the investigation stalls but crime rates continue to drop as he no longer has a threat of capture. Four years later, cults that worship Kira have risen.

Near arranges a meeting between Light and the current Kira Task Force members. Light tries to have Mikami kill Near as well as all the task force members, but Mikami's Death Note fails to work, having been replaced with a decoy. Perusing the names Mikami had written down, only Light's is missing, which proves Light is Kira. Light is grievously wounded in a scuffle and begs Ryuk to write the names of everyone present. Ryuk instead writes down Light's name in his Death Note, as
