Singing has been Eir Aoi’s passion all her life; she fronted a band she formed in high school. Her debut single was “Memoria”, the ending theme of TV anime Fate/Zero, which was #8 on the Oricon single chart and sold close to 60,000 copies.
Eir Aoi continued to produce many hit singles that were openings of anime such as: “Aurora”, the opening theme of TV anime Mobile Suit Gundam AGE: Third Generation series; “Innocence”, the opening theme of TV anime Sword Art Online: Fairy Dance series; “Sirius”, the opening theme of TV anime Kill La Kill; and most recently,”IGNITE”, the opening theme song to the popular TV anime series “Sword Art Online II”.
