See main article: Girls Planet 999. Kep1er was formed through the Mnet reality survival show Girls Planet 999, which aired from August 6 to October 22, 2021.

Before the show began, several group members had already been active in the entertainment industry. Choi Yu-jin made her debut in the Cube Entertainment girl group CLC on March 19, 2015, with the group's extended play (EP) First Love; she was on hiatus from CLC due to activities with Kep1er until their disbandment.[10] In 2010, Kang Ye-seo was a member of the girl group CutieL before joining Busters from 2019 to 2020.[11]
