|Anime Debut||Season 2, Episode 2: Clean-up!|
Girl7 is an anime-only band consisting of seven members, that made its first appearance in the episode Clean-up! on a flyer inside of a music store. Azusa and Mio had wished for more members for their own band after seeing Girl7's advertisement.
Girl7 is a pure girl group, but the musical orientation is unknown.
The fact that they have their own advertisements might mean that they are fairly skilled and famous.
The band consists of seven female members, hence the wordplay of the band's name. The full line-up is unknown, but one member is clearly the drummer while another one is a vocalist. Four of the other members play guitar or bass. The position of the last member is unknown.
