AOA 에이오에이 is an idol girl group signed under FNC Entertainment. Initially, AOA debuted as an eight-member band that consisted of Choa, Jimin, Yuna, Youkyung, Chanmi, Hyejeong, Seolhyun, and Mina. Currently, AOA is promoting as a six-member idol girl group without Youkyung, who was only a part of AOA Black, and without Choa, who left in mid-2017. The group officially debuted by having their debut music stage on August 9, 2012, on "M Countdown."
On October 15, 2016, FNC Entertainment released an official statement announcing the departure of Youkyung from the group, following the termination of her contract.
AOA is an acronym for "ace of angels."
The eight original members were introduced individually through teaser photos from July 16 to 23 (in order: Seolhyun, Choa, Hyejeong, Chanmi, Yuna, Mina, Jimin, & Youkyoung). AOA was revealed to be a dance group, with some members also playing instruments. Explaining the concept of their debut, FNC revealed that seven members are "full angels": Seolhyunari (Seolhyun), Choaya (Choa), Hyejeong.Linus (Hyejeong), Chanmi Titi (Chanmi), Yunaria (Yuna), Minaring (Mina), and leader Jiminel (Jimin), while Youkyoung (or "Y") is listed as a "half-angel/half-mortal"as she is only a member when the group promotes as a band. This is why AOA calls themselves a "7+1" group.
Angel's Story was leaked on July 28, two days before the official release. The music video for the lead track "Elvis" was released on July 30. AOA had their debut stage on August 9 on "M Countdown" and then "Music Bank" on August 10.

The album cover was released along with the announcement; the album cover depicted the eight members as different fictional characters. Hyejeong, Jimin, Choa, Yuna, Chanmi, Mina, Seolhyun, and Youkyung dressed as characters from Kill Bill, Léon, Legally Blonde, Tomb Raider, Harry Potter, Breakfast at Tiffany's, Romeo and Juliet, and The Fifth Element respectively.
