Kep1er
Six-member multinational girl group formed through Girls Planet 999, continuing its post-project era with a renewed lineup and a darker 2026 sound on CRACK CODE.
Profile
Kep1er was formed through Mnet’s Girls Planet 999 and debuted on January 3, 2022 with FIRST IMPACT and the title track “WA DA DA.”
The group originally debuted with nine members. MASHIRO and YESEO concluded their Kep1er activities in 2024. In March 2026, YOUNGEUN also concluded her activities after an extended health-related hiatus.
Kep1er now continues as a six-member group: YUJIN, XIAOTING, CHAEHYUN, DAYEON, HIKARU and HUENING BAHIYYIH. WAKEONE’s current official profile lists these six members.
On March 31, 2026, the group released its eighth mini album CRACK CODE, the first Korean comeback of the six-member era. The title track “KILLA (Face the other me)” moved Kep1er toward a darker electronic hip-hop sound and a more forceful performance concept.
