INNOCENCE

"INNOCENCE" is a song by Aoi Eir that became the second opening theme for the 2012 television anime Sword Art Online (ソードアート・オンライン). It was released on November 21, 2012 as Eir's fourth single for the series from A-1 Pictures, Studio 3Hz, and Polygon Pictures.

Eir wrote the title track, and Tom-H@ck composed and arranged it. The single appeared in limited, regular, and anime-limited editions, and a special Sword Art Online version also included "memoria," a song previously used as the ending theme for Fate/Zero. "INNOCENCE" was later included on Eir's first album BLAU.
