The official X (formerly Twitter) account for the upcoming Promise Me the Spotlight TV anime announced on September 21 that singer-songwriter Yuika will perform the anime's opening theme song "Nanimono demo Nakkatta Watashi dakara" ( Because I was nobody ). The song was performed for the first time exclusively for the attendees at her special one-man live concert "Sanvitalia," held at the Tokyo International Forum on the same day. The release schedule for the song was not announced at the time of reporting. Yuika also provided the following comment on the announcement: Since this is a work that I've originally loved and have read up to the latest volume, I was filled with joy and excitement, thinking, "I can't believe I get to perform the opening theme...!" Because there are so many parts in this work that overlap with my own self, I have the impression that "Nanimono demo Nakatta Watashi dakara" came together very smoothly. Of course, while staying close to the work, I am truly filled with happiness to be given the opportunity to write my own feelings like this! I wrote it while thinking that I want to give back to everyone at live performances, so I would be delighted if you listen to it a lot! Yuika is a singer-songwriter from Nara who made her major debut with Universal Music in 2024.
