On 31 August 2026, the unit Girls' Generation-HRS («HyorisU», 소녀시대-효리수, «Hyoryesu») made its official debut.

The group released a digital single, «Skibidi».

Though a single, the release contains two tracks:

«Skibidi»: The lead track opens in a house style before transitioning into hip-hop, and features Arabic string samples.

«Lowkey in Love»: A retro-style dance pop track with bold brass instrumentation and a rhythmic groove.

The unit's name is derived from the first letters of the members' names: Hyoyeon, Yuri and Sooyoung. It originated as a running joke on Hyoyeon's personal YouTube channel, «Hyoyeon's Level Up».

In several videos, the members playfully competed for the positions of main vocalist and centre of the group, which caught the public's attention and ultimately led to the formation of an official unit.

The unit jokingly bills itself as «6th-generation K-pop idols», despite its members being veterans with nearly two decades of experience.
