Under Girls

Undergirls (アンダーガールズ) is a special AKB48 single unit that is primarily responsible for performing the main B-side of most the group 's singles, as well as SKE48, SDN48, NMB48, JKT48, SNH48, and Nogizaka46.

Information

Under Girls was first introduced in AKB48's 13th single Iiwake Maybe, singing the B-side Tobenai Agehachou. It composed of the 9 girls that ranked 22-30 in the 1st Senbatsu Election. Since prior to this single the B-side was performed by the Senbatsu, the Undergirls unit provided many opportunities for new girls to participate in a single. Under Girls also became the first to have a PV.

When AKB48's 14th single RIVER was released, the Under Girls unit was used again for the B-side Kimi no Koto ga Suki Dakara, this time composing of 16 girls who were selected by management. This introduced the management-selected Under Girls, which were different in that members did not need to be ranked.

Under Girls was then used as the B-side in almost every following single from 2010 - 2013, while playing a vital role in the AKB48's Senbatsu Elections. The group's 23rd single Kaze wa Fuiteiru split the Under Girls into Under Girls, Under Girls Baragumi, and Under Girls Yurigumi.

Since then, Under Girls was used exclusively for Senbatsu Elections, with units such as Selection 16 from AKB48's 40th single Bokutachi wa Tatakawanai, and Jisedai Senbatsu from AKB48's 42nd single Kuchibiru ni Be My Baby providing opportunities for new girls.

Currently, Under Girls is composed of girls who ranked from #17 to #32 in the Senbatsu Election.
