After School

After School (Hangul: 애프터스쿨, Japanese: アフタースクール, is a South Korean girl group formed by Pledis Entertainment in 2009. They were known as the first group to debut with a unique admissions and graduation concept in Korea, where members are added or withdrawn in a natural manner. The band consists of eight members: Jungah, Jooyeon, Uee, Raina, Nana, Lizzy, E-Young and Kaeun. Graduate member Soyoung graduated from the group in fall 2009, Bekah officially graduated from the group in July 2011, and Kahi graduated in September 2012.

Kahi and Jungah first performed alongside labelmate Son Dam Bi in 2008. After School officially debuted in January 2009 with the song "AH!" with the five original members being Kahi, Jungah, Soyoung, Juyeon, and Bekah. After concluding their debut song promotions in mid March they made a comeback with a new member UEE in early April with "Diva". Once Soyoung graduated after "Diva" promotions, two new members, Nana and Raina were added for the popular hit single "Because of You", which attained No. 1 and a triple crown on SBS's Inkigayo. Afterwards, After School released "Bang!" with the addition of Lizzy and "Shampoo" where E-Young was added. Shortly after, Bekah graduated After School and After School made their debut in Japan.

The group began a foray into the Japanese music scene in 2011 under Avex Trax with a remake of their Korean hits "Bang!", "Diva" and "Because of You". The group also released an original Japanese song titled "Rambling Girls" in January 2012. Their debut in Japan was quite a success, as the group managed to enter the Oricon Weekly Chart at number seven. The group's debut Japanese album, Playgirlz, debuted at number eight on the Oricon Weekly Album Chart.

In April 2012, Pledis confirmed the addition of Kaeun for the fifth maxi single in June. On 5 June 2012, it was reported that Kahi would graduate from the group in September 2012 to conclude promotions in Japan but not participate in group activities in Korea.
