C-Kira

C-Kira's identity, including their gender, is never revealed. The brief glimpses of their living space show shelves crowded with collectible figures evoking tokusatsu superheroes and magical girls, a strong hint that the killer is an otaku.

C-Kira stands apart from every other wielder of the notebook in the series. Rather than passing judgment on criminals, they take only the lives of elderly people who wish to die, an act closer to assisted suicide than execution. Near suspects the killer began after ending the suffering of an ailing grandparent and then came to imagine themselves as Kira's heir. Their resolve, however, proves fragile. Having traded for the Shinigami Eyes, they kill freely until challenged, yet they lack the conviction that carried earlier users.

Near, speaking under the L alias, dubs this fifth Kira "C-Kira," short for Cheap Kira, a jab at deaths he regards as little more than mercy killings. He publicly declines to pursue the case, writing the culprit off as nothing but a murderer. The rejection shatters C-Kira completely: the killings abruptly stop, and Midora later tells Ryuk that the user went pale, stared at a wall for three days, began screaming, and finally wrote their own name in the notebook. Ryuk answers by recalling Light Yagami's belief that wielding the Death Note demands real emotional strength and conviction. The movie Death Note: Light Up the NEW World offers a loose reworking of the figure in Alexey Ivanov, a physician who launches a wave of assisted suicides across Europe.
