Undead (Yoasobi song)

"Undead" (Japanese: アンデッド, Andeddo) is a song by the Japanese music duo Yoasobi, released on January 19, 2024. It served as the theme song for the anime series Frieren: Beyond Journey's End.

The song is based on the original story Frieren and the Funeral March (Japanese: フリーレンと葬送の行進, Frieren to Sōsō no Kōshin), written by Kanehito Yamada, the author of the Frieren: Beyond Journey's End manga. The story depicts Frieren's internal struggles and reflections on her long life and the fleeting lives of those around her.

Musically, "Undead" continues Yoasobi's signature style of blending J-pop with elements of electronic and rock music. The lyrics explore themes of immortality, loss, the passage of time, and the acceptance of mortality. The song's title, "Undead," refers not only to the literal immortality of the elf Frieren, but also to the lingering memories and emotions that persist even after death.

The release was accompanied by an animated music video that visualizes the themes and characters from both the anime and the original story. The song quickly gained popularity, charting on various music platforms and contributing to the continued success of Frieren: Beyond Journey's End.
