A three-member multinational boy group from Rain Company that debuted on March 15, 2021.
'Ciipher' means 'those with a password', meaning 'we will approach you in a friendly manner off stage, but show a strong appearance with a password on stage'.
The slogan among the members seems to be "Can't sleep? No! We have to be cool! Let's go!"
On August 9, 2023, members Tan, Tag, Dohwan, and Won left the group, and the remaining members decided to continue their individual activities, effectively disbanding the group.
