On September 27, 2021, Ai announced on her social media of a song she recorded for an upcoming NHK TV series. Written by Naotarō Moriyama and featuring arrangements by Neko Saito, the song is named after the star of the same name in the Taurus constellation. Regarding the song, Mone Kamishiraishi, one of the actresses to be in the film, commented that the song was "beautiful" and "nice and encouraging". Eri Fukatsu also commented she was wary of Ai's recording but stated, "My heart was shaken, robbed and filled." Actress Rina Kawaei, also an actress in the film, commented that she was "impressed by the gentle singing and the wonderful lyrics". The song was originally written by Moriyama on New Years in 2021 about environmental issues and was originally titled "Daphnia Pulex". "Aldebaran" was not intended to be the theme song for Come Come Everybody until Moriyama allowed Ai to record the song with reworked lyrics. Promotion
