Voiced by: Kimiko Saitō (Japanese), Colleen Wheeler (English) Shinnosuke Ikehata (movie) Rem is the Shinigami who first gives Misa her Death Note and Shinigami eyes. Similar to Ryuk, Rem possesses two Death Notes; she purposely gives a Death Note to Misa. Rem inherited her second Death Note from Jealous, another Shinigami who died when he saved Misa's life, and thought it only right to pass it on to Misa. Rem inherits Jealous' love for Misa as well and is prompt to defend Misa even at the cost of her life. She shows this when she openly shows her lack of trust for Light stating that if Misa dies before her time, Rem will kill Light. Rem dies after she is tricked by Light into killing L and Watari to protect Misa. In the second movie, Rem, voiced by Shinnosuke "Peter" Ikehata, declares her love for Misa and her spite for Light moments before her death. While she dies, she burns her note in a blue flame entrusting that it will never belong to Light, but this is not the case in the manga and anime where Light is able to retrieve the notebook.

In the manga and anime, Rem tells Misa that she is actually a female Shinigami. In the second live-action film, this is not mentioned, leaving it ambiguous. She is also given a more masculine voice.
