Muse

μ's (pronounced "Muse") was a school idol group formed and led by Honoka Kosaka in Love Live!. They were the school idol group of Otonokizaka High School. The group consisted of nine members and was initially formed with the purpose of bringing attention to the school as it was to be shut down due to a lack of future enrolling students. The group disbanded in the anime after the 3rd years graduated, staying true to their status as school idols, unlike their rival A-RISE, which choose to stay as an idol group even after school. In other words, μ's no longer exist as an idol group. However, they did make their final appearance in the movie.

Their real life parallel of the voice actresses ended activities as a group on April 1, 2016 with the Final Live, ending their legacy. However, it was announced that the group would be returning with a new single, which was released on March 25th, 2020. They also performed at the Love Live Fest in 2020.

Etymology
The name "μ's" came from Greek Mythology's 'nine goddesses of music', which consists of nine members.

In the anime, Nozomi Tojo is the one who grants the group this name by placing it in a box. In the manga, however, it is Honoka Kosaka who does by writing the name on her own in Love Live! submission form. However, despite the meaning of the group's name, μ's had performed several times without all nine members present in the anime. In addition, three of the six insert songs in the movie (Hello, Hoshi o Kazoete; ？←HEARTBEAT and Future style) are performed with only 3 members of the same year from each song.
 * 3 members in Season 1 Episode 1 (Susume→Tomorrow) and Season 1 Episode 3 (START:DASH!!).
 * 7 members in Season 1 Episode 6. (Korekara no Someday)
 * 6 members in Season 2 Episode 5. (Love wing bell)

In reality, the group name "μ's" was decided through a cellphone poll by fans, with voting taking place between October 30 - November 14, 2010. The nominated candidates were:
 * μ's
 * Otonokizaka Nonetto
 * Livestar!
 * Little Diamond
 * Otonokizaka Idol Club

Trivia

 * During the early months of the project, the group was actually named "Love Live!". This was before any concrete plot had been conceived yet.
 * Several polls determined the names of the subunits: Printemps, BiBi, and lily white.
 * Based on polls, the member with the most votes would be given the center position of the next music video. For example, Nico was the center of Natsuiro Egao de 1,2,Jump! (夏色えがおで1,2,Jump!) because she won a poll.
 * For some music videos, polls also determined the idols' hairstyles and costumes.
