SM Entertainment announced the formation of Girls’ Generation-HRS, a new sub-unit consisting of members Hyoyeon, Yuri, and Sooyoung. The group’s origins trace back to a humorous digital project on Hyoyeon’s YouTube channel, ‘Hyo’s Level Up’. This project, described as a mockumentary series titled ‘Fake Kim Hyoyeon’, depicted a comedic rivalry between the trio and the vocal sub-unit Girls' Generation-TTS.

Following a live preview at the 2026 CassCool Festival in Gwacheon, the unit officially debuted on August 31 with the digital single ‘Skibidi’. The title track blends house and hip-hop with Arabian-inspired string samples and centers on the theme of ‘paving a new path’. The release also includes the B-side ‘Lowkey In Love’, a retro-inspired dance-pop track characterized by upbeat brass sounds and a rhythmic groove.

While the unit faced some criticism regarding its appeal to older fanbases, the project transitioned into a formal debut following significant online interest. Pre-release footage from the CassCool Festival garnered over 800,000 views within four days, highlighting the group's continued relevance twenty years after their original debut.
