The title track is the theme song of the live-action adaption of collectible card game and anime Aquarian Age (specifically, one of the stories, Juvenile Orion), in which the band also appears.

The limited editions contain a second B-side, "Kiseki," and an additional DVD with a single music video.

The song "Mirror Ball" was later rearranged with piano accompaniment for the band's third album, Vandalize.

After reading the film's script, the band decided that the theme for the song would be "human's light and shadow."

The music video shows some focus on singer Shou, who acts as a jaded prisoner with gray colored hair.
