In the sequel movie, it takes place 10 years after the end of the movie where there will be a battle over the ownership of six volumes of the Death Note scattered at different locations on Earth. Higashide plays Mishima, an assistant inspector who is the leader of a team set up to deal with Death Note-related cases and knows a lot about what happened 10 years ago, Ikematsu plays Ryuzaki who is the successor of L while Suda plays a terrorist Shion who idolises Kira (Yagami Light) and gets involved in the battle over the ownership of the Death Notes.
Higashide commented that he is very happy to be able to participate in the movie especially since he had read the manga and watched the original movies 10 years ago. Ikematsu said that although he was prepared for negative remarks about his character which can be said to be born from Matsuyama's very successful and popular character, he hopes that his performance will exceed expectations. Suda also revealed that he hoped that their movie will be even better than the original movies.
