Echigo Sisters Geeks

 (越後未希Geeks) was an underground Idol J-Pop group based in Niigata, Japan. They were formed in 2013, and worked for a race team as race queens for their main job, and idol as second. They mainly performed covers of Love Live! songs at events that usually took place at racetracks or car shows.

The group disbanded on June 11, 2017, after differences between Akari & Yukari and the management.
