AOA Black is a sub-unit of AOA. The sub-unit doesn't have the sexy image that the main groups has. Instead they have a band concept and play their own instruments. The group used to have 5 members: ChoA, Jimin, Youkyung, Yuna and Mina. ChoA left FNC Entertainment and AOA in 2017. Youkyung left the agency, but she will participate in AOA Black comebacks as a guest member.
