L.M.B.G (Little Marching Band Girls) is a 20 person idol unit in Idolmaster Cinderella Girls featuring many of the youngest and smallest girls of the cast. Originally beginning with two members (Sasaki Chie and Yokoyama Chika) on its debut in September 2013, it slowly accrued additional members, with the 20th member being added in December 2019.
In the spin-off game Starlight Stage, it appears as a five-member unit with the debut of their song Hi-Fi☆Days on March 31st, 2016, due to most of the other members being unvoiced.
On June 19th, 2017, the Starlight Stage unit was featured for a second time, in the debut event for the mobile game version of the song Yes! Party Time!!, from the PlayStation VR spin-off game Idolmaster Cinderella Girls Viewing Revolution.
