As One (girl group)

As One (Korean: 에즈 원; stylized as AS ONE and in South Korea as AS1 to avoid confusion with the musical duo of the same name) was a Hong Kong Cantopop girl group formed by Sun Entertainment Culture and choreographer Sunny Wong.

The meaning behind the group's name is based on the concept of unity, with the members united together "as one". The group was consisted of four members; Shin, Oli, Elfa and Nata. The group promoted as a quartet for two years until Oli's departure in August 2014 to pursue her studies. Subsequently, two new members (Chloe and Kayan) joined the group in March 2015 after emerging as champions of a scouting audition. Elfa announced her temporary hiatus from the group in May 2015 due to sustained injuries. As of 15 May 2015, As One is promoting as a quartet with Shin, Nata, Chloe and Kayan.

They were trained in South Korea and made a comeback in 2015. Shin participated in South Korea Mnet's survival show Produce 101 in 2016; during this time, the group continued with three members.
