Oorutaichi's first release in three years. It is the leading single from his forthcoming new album, which is scheduled for release in November. It is a double-track single which includes "Futurelina" and "Moeru Himitsu featuring Kicell". "Futurelina" is an up-tempo electronic tune and a regular repertoire at his shows. "Moeru Himitsu feat. Kicell" is a song in which pop duo Kicell renders their vocals on top of Oorutaichi's track, sounding like a 21st-century folk song with its combination of programmed and real instruments. (Moeru Himitsu means "Burning Secret") Kicell is one of the most popular young singer duos in Japan.
