The duo first collaborated on the song "Color," which was used as the opening theme to the 2010 anime Freezing. The name of their unit came from the French phrase "Le Palais Garnier de Maria" (Maria's Opera), and the asteroid Cordelia, which was discovered in 1978, the year of Toku's birth.

In 2014, they made their debut under major record label Defstar Records with the single "ambiguous," which was released on March 5, 2014. Its title track was used as the second opening theme to the 2013 anime Kill la Kill.
