death note: lawliet
As there is no time delay between the first and second films, the second film begins soon before L supposedly dies. L retains many of the same characteristics seen in the original series. At the end of the first film, L eats potato chips in front of Light; Light had used a potato chip sack to hide a mini LCD television from security cameras while L filmed his room.
Unlike the manga and anime, in the second film, his original "death", caused by Rem writing his name in her Death Note, does not take effect, as L had written his own name in Misa's Death Note earlier. It is his self-sacrifice that allows himself stay alive for a longer duration (as he supposed Kira would kill him on that day), and allows the investigation team to apprehend Light. After Ryuk kills Light, Ryuk offers L the Death Note. L refuses, and Ryuk, while saying that L is boring, leaves.
Twenty-three days after writing his name in the Death Note, and after burning all the remaining Death Notes and having a conversation with Soichiro, L dies peacefully while eating a chocolate bar, with a picture of Watari lying right beside him. He is portrayed by Ken'ichi Matsuyama, who also voices Gelus (Jealous) in the anime.
L was also similar in the film L: Change the WorLd which takes place in the 23 days that L has left before he dies. In it, L decides to solve one last case. He is in charge of stopping a deadly virus from spreading across the world. Ryuk comes to his aid on behalf of Kira's last wishes. Hideo Nakata, the director, told The Daily Yomiuri that he wanted to exhibit L's "human side" that was not exhibited in the Death Note series.
Matsuyama said that L and Light are "extremely" alike in that they have "very strong sense of justice."
