-ERROR

Background
This is a powerful rock song. The lyrics are vague and open to interpretation. It is one of Niki's most popular songs as well as one of the most popular songs featuring Lily. A Namine Ritsu cover of the song by cillia brought attention to the song "-ERROR". It was popular enough that KarenT licensed a single to the song "-ERROR", however, with Namine Ritsu as the vocals, not the original sung by Lily.
