Plot
Ten years after the confrontation between L and Light, Shinigami bring Death Notes to the the human world as they take advantage of the rule that only a maximum of six Death Notes can be active. Following in Soichiro Yagami's footsteps, Tsukuru Mishima leads a newly created Death Note Task Force and works with Ryuzaki, an investigator claiming to be the true successor of L, to secure all six notebooks. Yuki Shien, a cyber-terrorist and Kira supporter, also emerges to seek out the notebooks.

Towards the end of the movie, it is revealed that Mishima was secretly also a Kira supporter and acted as "Neo Kira" after killing and obtaining a Death Note from Teru Mikami, who first stole the notebook from Hikari Yagami, Light's son. In an effort to continue Light's mission of world peace, Mishima uses the notebook to kill criminals and temporarily forfeits his ownership of the notebook in an attempt to ward off suspicion, but not before writing Ryuzaki's name in advance to be killed.

Shien, who was aware of Neo Kira, attempts to kill Mishima to presumably to take his place, but dies as the police close in on Mishima. A remorseful Mishima is subsequently incarcerated, but Ryuzaki, shortly before his scheduled death, names Mishima as his successor and frees him. The movie ends with Mishima attempting to make amends by setting off to secure the remaining Death Notes.

Reception
The film topped the Japanese box office its opening weekend, beating the popular film Your Name. (Kimi no Na wa.) which had held the top for nine consecutive weeks. Within a month of opening, the film earned over 2 billion yen (about US$17.85 million) and had sold over 1.5 million tickets.

It averaged 2.8 out of 5 stars on Eiga.com, 2.73 out of 5 stars on Yahoo, and 6.5 out of ten stars on IMDB. The main criticism of the film was that it was not as clever as the previous ones with little reminiscent of the intellectual games that were played between L and Light. Misa's role was generally praised, as were the CGI of the shinigami.
