Bara no Seidou is a major change from Malice Mizer's previous albums with less of a focus on the twin guitar sound that was present in their previous discography, but retaining a chameleon trait like artists such as Genesis and Roxy Music. The band's sound switched from a normal art rock sound into a dark, gothic metal one; however, they still continued to use the violins, harpsichords and other instruments present in their older works and also added in a pipe organ and a choir for a haunting, melancholic, and religious feel to the album. For example, the song "Seinaru Toki Eien no Inori" is based around an organ and choir but still includes dual guitars and drums, which gives it a gothic metal feel. Fan favorite "Kyomu no Naka de no Yuugi" is a track that uses an organ and harpsichord mixed with a synthesizer and drum machine for more of a dark wave element. This song is influenced by gothic rock/industrial music and features a different image in its video, but still retains the dark themes of the album.
After the death of Kami, it could be argued that the "funeral goth" element present in their attire is because of his death, and the song "Saikai no Chi to Bara" is a reference, and tribute, to him.
