Kep1er Members Profile 2026: Bio, Age, Career & Interesting Facts
Kep1er (케플러) stands as one of the most remarkable success stories in the K-pop industry. Formed through Mnet’s survival show Girls Planet 999 in 2021, this multinational girl group captured the hearts of fans worldwide with their powerful performances, exceptional talent, and inspiring journey. But who are the members of Kep1er in 2026? What is their story, and what makes them so special?
Kep1er is a South Korean multinational girl group formed through Mnet’s survival show Girls Planet 999 in 2021. They debuted on January 3, 2022, with the song “Wa Da Da.” As of 2026, Kep1er has six members: Choi Yujin (leader), Shen Xiaoting, Kim Chaehyun (center), Kim Dayeon, Ezaki Hikaru, and Huening Bahiyyih. Their fandom name is Kep1ian. The group made history as the first project group from an Mnet survival show to renew their contracts. Their latest release is the eighth mini-album CRACK CODE (March 31, 2026) with the title track “KILLA (Face the other me)” .
Kep1er debuted on January 3, 2022, with nine members representing South Korea, Japan, and China. The group’s name combines “Kep” (representing capturing dreams) and “1” (symbolizing unity)-a fitting name for a group that brought together talents from across Asia. Their fandom name is Kep1ian (케플리안).
What makes Kep1er truly unique is their historic contract renewal. Unlike most project groups formed through survival shows, Kep1er became the first of its kind to renew its contract and continue promoting beyond the typical 2.5-year project期限. While three members-Mashiro, Yeseo, and Youngeun-departed between 2024 and 2026, six members continue their journey together.
