The band's members, who include male and female twin vocals, flute and oboe, play the roles of characters while performing, creating a stage work in which the story progresses. The band's live performances are a fusion of stage and video, and include dancers and stage actors as guest performers, and they are pursuing further possibilities for visual-kei bands.
The band's music is characterized by a band sound with male and female twin vocals, a full orchestra including a full-time flute and oboe member, and a large symphonic sound with a mixed chorus.
