Conqueror is the sixth studio album by the Japanese all-female rock band Band-Maid.

[8] The album includes a lot of mid-tempo songs, because they felt that their fans were exhausted from their live shows and that they needed to rest.

[14] Rhythm guitarist/vocalist Miku Kobato stated that the English lyrics in the song were made intentionally easy to sing, as they found that many kids watched the show.

[13] The drums are a mix of live and electronic sounds[11][12] Tōno wrote the music for "Azure" after she learned of the passing of manga artist Momoko Sakura.

[17] They were originally going to use one of their unreleased songs for the show, but Tōno "realized that the demo I just happened to be working on at the time was a better fit for the drama.

"[18] During the recording of the album, Band-Maid was contacted by producer Tony Visconti, who had learned about the band from songwriter Tom Kenney.

[19] Visconti invited band members Saiki Atsumi and Kobato to travel to a studio in New York City, where he produced the vocal tracks for the song "The Dragon Cries".

[20] Tōno sent Visconti a demo of the song's musical backing, expecting him to want to rework it, but he declared that it needed no alterations.
