アンダーガールズ | fr

The Undergirls (アンダーガールズ, or Under Girls) are a special group/team of girls that, since the term was included in the 1st Senbatsu Election, take charge of the main B-side of most of the AKB48 Singles and recently also SKE48, SDN48, NMB48 and Nogizaka46 (also under the name Under Members) Singles.

The Undergirls were introduced in the 1st Senbatsu Election, where the girls that ranked from 22 to 30, were given the chance to sing the B-side track of the election single Iiwake Maybe. Previous to this, all the original B-sides were also done by the Senbatsu of that single. This now gave the chance to a lot of other girls to actually take part in a single release (with most of the them doing it for the first time).

The first Undergirls generation, consisted of 9 girls and they sung the track Tobenai Agehachou, which also got a PV, marking the first time an AKB48 B-Side got a Music Clip.

Later on for the next single RIVER, the Undergirls concept was used again, however this time, the manager decided the members, creating an almost completely different selection of girls compared to the first generation.

The Undergirls weren't used in the following single (Sakura no Shiori), but made a comeback in Ponytail to Shushu, being used in all singles until GIVE ME FIVE!, when Undergirls were replaced by Special Girls. They would then return on Gingham Check.

The Undergirls concept is not used on Janken singles, such as Chance no Junban and Ue Kara Mariko. On Kaze wa Fuiteiru, the Undergirls were divided in three groups: Undergirls, Undergirls Baragumi and Undergirls Yurigumi.

For SKE48's 3rd Single Gomen ne, SUMMER, the Undergirls concept was implemented with SKE48 for the first and only time. In contrast to AKB48, 2 different groups of Undergirls were used in the same single (Undergirls A and Undergirls B). Both groups featured a small group of girls and sung different songs. Undergirls A was an exclusive-track and music Video of Type-A ane Undergirls B were an exclusive track and music video of Type-B.
