About the song
The song was first released digitally on April 22, 2019. The physical single of the same name, which includes the songs "PROPAGANDA" and "Yakusoku no Uta", was released on July 3, 2019 under Sony Music Entertainment's Sacra Music label.
It was used as the opening theme song for the TV anime adaptation of the manga series Demon Slayer: Kimetsu no Yaiba. It was noted that the lyrics of both the TV-size version and the full length version had some differences, and according to LiSA herself, those changes were made because she felt that "It was too cruel to thanking the sadness at the beginning of the story of Tanjiro (the protagonist of the manga)".
It was first included in Taiko no Tatsujin: Green Version with Japanese version's version 6.02 update on the arcade platform.
