We All Need a Hero

"We All Need a Hero", alternatively "My Hero", is a song in Death Note: The Musical.

Overview
After seeing Misa Amane's concert, Light Yagami tells Sayu Yagami that he liked the opening when Misa thanked her "beloved hero" Kira. But Sayu says she didn't like that part. When Light asks her what she would say to Kira if she could, she would tell Kira to be more like her brother, and she sings this song about how Light's her hero. Resting after her performance, Misa begins singing the song as well, but she's singing about how Kira is her hero instead. Although he doesn't sing, Light moves center stage with Ryuk, halfway between Sayu and Misa, symbolically split between the two opposing aspects of himself.

English version
The song was originally written in English, but an English-language version has not been released. The original English title of the song is "We All Need a Hero".

On October 13, 2017, script-writer Ivan Menchell shared the English lyrics when a fan asked him on Twitter.
