Who Is HIER?
HIER is a five-member boy group currently operating under KNEX Global. The group introduced itself to the public in September 2026 through a series of individual profile photos and a group image shared on its official social media channels . The name HIER is written as 하이어 in Korean, which is phonetically equivalent to the English word “Higher” .
Unlike groups formed through televised survival shows or large-agency trainee systems, HIER has entered the public eye through a self-described “Pre-Debut Project” – a series of live performances in Japan designed to build a fanbase before an official debut . The group’s current status is best described as pre-debut: members are performing publicly, but no debut single, EP, or album has been released.

How HIER Was Formed
Information about HIER’s formation process remains limited. The group is associated with KNEX Global, a name that appears in official promotional materials and hashtags used by the group’s account . Details about how the members were recruited, whether through auditions or agency scouting, have not been publicly disclosed by the agency.
What is clear from official materials is that HIER’s rollout has followed a deliberate visual-first strategy. Between early and mid-September 2026, the group released individual member portraits with a minimalist white background, followed by a group photo showing all five members lying in a circle . This approach – introducing members individually before revealing the full group – is a common pre-debut tactic in K-pop, designed to build curiosity and allow fans to form early attachments to specific members.
Official Debut
HIER has not officially debuted. No debut date, debut single, or debut album has been announced by the agency or the group’s official channels. The group is currently in a pre-debut promotional phase.
