Celest1a (셀레스티아) was a South Korea-Japan collaborative boy group formed under Birdman, active briefly in 2024. The group consisted of eight members: Akito, Daisuke, Minwook, Junhyeok, Hayato, Sejin, Seunghyun, and Seokhee. Known for their dance-pop sound, they debuted on July 31, 2024, with the digital single "Panda." The group’s fandom was named Ste11a, representing their celestial concept. Pre-debut, the group gained attention as the product of the reality show K-POP HOUSE, produced by Super Junior’s Eunhyuk and ONE PACT’s Jongwoo. Members were introduced progressively, starting on February 15, 2024. However, Celest1a faced challenges even before debut, with Seunghyun temporarily stepping back due to sudden hearing loss and Hayato briefly halting activities after violating his contract. Their debut single "Panda" showcased vibrant choreography and catchy melodies, establishing a promising start. However, internal setbacks continued, including Seokhee's suspension of activities in September 2024. Just three months after debut, on November 1, 2024, Celest1a announced their disbandment through social media, with heartfelt farewell letters from all members.
