BiBi

BiBi is a sub-unit under μ’s. The unit consists of three members, namely leader Eli Ayase, Maki Nishikino, and Nico Yazawa.

Group Formation
In the anime, the unit was formed by drawing lots.

In real life, the unit was formed in phases


 * 1) March 2011, the three unit leaders, Honoka Kosaka, Umi Sonoda and Eli Ayase were revealed with this key visual. People were then given five sets of possible unit compositions, and asked to vote for which members should belong in each leader's sub-unit.
 * 2) April 2011, the new unit compositions were revealed, and people were asked to submit names for them
 * 3) May 2011, the chosen unit names were revealed.

Etymology
Due to the image presented by the members, many of the name submissions to the staff had an adult and graceful feel to them. BiBi's name was meant to symbolize the sharp style and fashion exhibited by members of the group. Other highlighted submissions included "Grace Maiden" and "Shiny Silhouette."

Trivia

 * Due to Maki, Eli, and Nico all being individually popular, as well as Nico and Maki being a popular pairing, BiBi has always been the most popular sub-unit with single sales above the other two units.
 * BiBi's trademark introduction at live concerts involves them shouting BiBi multiple times, with the audience repeating it back to them with the same beat.
 * In the anime, only Eli, Nico and Maki, or BiBi collectively, were directly invited by Honoka to become a member of μ's.
 * As named by Love Live! School Idol Festival ~after school ACTIVITY~, this sub-unit's outfit in Diamond Princess no Yuutsu is named "Leather Gloss Queen". The other sub-units' outfits are also named by the same source.
