After the band started, Haruichi asked Akihito Okano and Tama to join.

Their two subsequent CD singles, Saudade and Agehachō, both sold over a million copies in Japan.

The band is well known for their work in creating music for anime series and movies.

They are particularly well known for the song "Melissa," which was used as the opening theme of the anime series Fullmetal Alchemist in 2003.

Their single "2012Spark" was featured as the main theme song of the movie Gyakuten Saiban and their single "Matataku Hoshi no Shita de" was the second opening theme for the anime Magi: The Labyrinth of Magic.
