Loona

Loona (stylized in all caps or as LOOΠΔ; Korean: 이달의 소녀; lit. 'Girl of the Month') is a South Korean girl group created by Blockberry Creative. The group is composed of eleven members: Heejin, Hyunjin, Haseul, Vivi, Yeojin, Kim Lip, Jinsoul, Choerry, Yves, Go Won, and Hyeju (formerly Olivia Hye). Originally a twelve-member group, Chuu was removed from the line-up on November 25, 2022, due to a contract dispute. The remaining members of the group departed Blockberry Creative later that year, putting the group on an indefinite hiatus.

The group debuted as a full ensemble on August 19, 2018, with the extended play (EP) [+ +], supported by the lead single "Favorite" and the title track "Hi High". The group debut was preceded by an 18-month-long debut project, with monthly promotional singles, each revealing another member of the group.

From 2022 to 2023, after a series of lawsuits, Loona members terminated their contracts with BlockBerry Creative and signed contracts with new labels: YeoJin, Go Won, HyeJu, HyunJin, and ViVi signed with CTDENM and re-debuted as Loossemble in September 2023; Yves signed with Paix Per Mil and made her debut as a solo artist under the company in March 2024; while HeeJin, Kim Lip, JinSoul, Choerry, and HaSeul signed with Modhaus and re-debuted as Artms in May 2024.

Name

Loona's English name is derived from the Hangul letters ㅇㄷㅇㅅㄴ, each an initial consonant in the syllabic blocks that make 이달의 소녀 (Idarui Sonyeo). When rearranged to ㄴㅇㅇㄷㅅ, it resembles LOOΠΔ or LOONA in the Latin alphabet.
