Mephisto (song)

On March 2, 2023, Queen Bee announced that they would perform the ending theme of anime series Oshi no Ko, titled "Mephisto", alongside the band's Japan tour Mephisto Shōkan.^[2] The single was released to digital music and streaming platforms on April 20, and on CD single on May 17 with two versions—limited and anime editions.^[3] The music video, directed by Sayaka Nakane, was uploaded on May 17, depicting the life of idol Avu-chi. It stars the band's members, and actress Karin Ono.^[4]

Titled after German folklore demon Mephistopheles, lead vocalist and songwriter Avu-chan explained to Billboard Japan in August 2023 that they used the motif of the legend's protagonist Faust for the main idea of "Mephisto", alongside authors who "richly depicted the doings and passion of people", e.g. Go Nagai, Yukio Mishima and William Shakespeare.^[5]
