Fighter

"Fighter" is a song performed by Japanese singer Namie Amuro. It is the ending theme song for Death Note: New Generation and an insert song for Death Note: Light Up the NEW World.

The song was created specifically for the film. It is officially described as a dance number written from the point of view of the character Misa Amane. The song plays when Misa is introduced during a photo shoot.

"Fighter" was written, composed, and produced by Japanese vocalist Emyli, with additional production credits to Reason.

Release and reception
Along with the theme song "Dear Diary", it released on the single "Dear Diary / Fighter" on October 26th, 2016. The single also includes an instrumental version of the song, and the special edition of the single comes with a DVD featuring the music video for the song. A digital version was released on November 16, 2016.

"Fighter" was a commercial and critical success and received positive reviews from music critics and fans alike. The song contributed to Amuro's nomination for Best Female Artist at the Space Shower Music Awards. The song peaked at number three on the Oricon Singles Chart.

There was some criticism for using a Japanese performer for the song, since the previous Death Note films had used Western performers such as the Red Hot Chili Peppers and Lenny Kravitz which gave the films an international feel. A producer for the film, Takahiro Sato, originally intended to bring back either of those artists to provide the songs for the film, but since the series was already popular internationally, he decided to instead promote a Japanese performer and selected Amuro.

Music video
The music video of the song is included on the Deary Diary / Fighter special edition single that comes with a DVD, and a short version was released on Amuro's YouTube channel. The music video was directed by Higashi Hiroaki.

The music video is mainly set in a large cubical fortress which is floating above the ground and held down with large chains. It features the shinigami Ryuk, Arma, and Bepo from the film. Amuro explores the rooms of the fortress and interacts with the shinigami, such as sitting with them at a dinner table which is covered with bowls of apples and grapes. In another scene with white heavenly imagery, Arma is behind Amuro and her long arms wrap wide around Amuro, and Amuro has a similar interaction with Bepo in a dark forest.
