Utsukushiki Zankoku na Sekai (美しき残酷な世界)

“Utsukushiki Zankoku na Sekai” is a song performed by Yoko Hikasa. It serves as the ending theme for Shingeki no Kyojin (進撃の巨人), known in English as Attack on Titan, the 2013 anime series associated with Wit Studio, Production I.G, and MAPPA. The track was released in 2013 as the single “Utsukushiki Zankoku na Sekai” on September 4 of that year.

Hiroyuki Sawano composed the song. Its arrangement combines orchestral elements with rock, and the song is classified as J-Pop. Hikasa is also known for her work as a voice actress in various anime series. In Shingeki no Kyojin, the recording occupies the ending-theme role rather than serving as an opening or insert song, and it is credited to Hikasa as the real performing artist rather than to a fictional anime character.
