LOONA (Hangul: 이달의 소녀), stylized as LOOΠΔ, is a South Korean girl group created by BlockBerryCreative. The group is composed of 12 members: HeeJin, HyunJin, HaSeul, YeoJin, ViVi, Kim Lip, JinSoul, Choerry, Yves, Chuu, Go Won and Olivia Hye; and three sub-units: LOOΠΔ 1/3, ODD EYE CIRCLE, and yyxy.

From October, 2016 until June, 2018, each member of the group was revealed along with a single album and a music video for the title track. The complete group debuted on August 19, 2018 at their concert LOONAbirth with the release of + + on August 20, 2018.


The group's Korean name is 이달의 소녀, romanized as Idalui Sonyeo, from the Sino-Korean root meaning "Girl of the Month". Since their name consists of Chinese roots, the group's name is similar in Chinese and Japanese: in Japan the group's name is pronounced as Kongetsu no Shōjo (Japanese: 今月の少女), and in Mandarin Chinese as Běnyuè Shàonǚ (Chinese: 本月少女).

They are also known as LOONA, often stylized as LOOΠΔ, which is their official English and international name. This name is created from a rearrangement of the first constants of the hangul that spells out their name. In other words, ㅇㄷㅇㅅㄴ is rearranged to ㄴㅇㅇㄷㅅ, which then becomes LOOΠΔ. We also see this arranging in each introductions to LOONA videos.


2014-2016: CreationEdit

Before the selection of the members, LOONA's concept was first devised by their former A&R Director, Jaden Jeong. Prior to being introduced to Polaris Entertainment, BlockBerryCreative's sister company, Jaden Jeong already had the "Girl of The Month" Project planned. Despite already working with numerous other agencies, he waited for a company that had the will to properly bring the project "into reality". His goal with LOONA's project was not just to have a complete group, but also to have an identity and fandom.[1] In 2014, plans were made to establish a new agency consisting of a "dream team" in the industry. This agency would later become BlockBerryCreative in early 2016.[2]

In order to select the members of LOONA, trainees were split into groups based on skill level.[3] Each time a new member would be chosen, each group would send a representative that would compete for the spot. These representatives would be judged on group evaluations, including singing and a choreography test.[4] Additionally, the trainee's character and personality were also considered.[2] After each competition, the girls were ranked. The 1st girl would become a member while the 2nd and 3rd could choose different teams to join.[5]

In an interview with the CEO of Polaris Entertainment, released on August 24, 2018, it was revealed that the entire pre-debut project cost around $10,000,000. Due to interest from large organization, the project was able to receive a large amount of money through sponsors from Korea, Japan, and the United States.[2]

2016: Pre-debutEdit

On September 26, 2016, the first teaser of member HeeJin was released across multiple social media platforms including Youtube, Instagram, Facebook, and Twitter. Teasers for "HeeJin" were released until October 5, when the music video for "ViViD" was released.

2019: First comebackEdit

On January 1, a teaser titled "X1X" was released, teasing their next comeback. Two days later, it was announced the group will hold a concert, LOONAVERSE Concert, on February 16–17 to coincide with the new album, X X. As hinted at the end of the "X1X" teaser with four numbers (1, 11, 21, 31), LOONA released a teasers on the 11, 21, and 31 of January.

On February 16 and 17, LOONA held their concert, LOONAVERSE Concert. On February 19, the music video for "Butterfly" was released, coinciding with the release of X X. The X X promotional period lasted six weeks.

On February 19, it was revealed that all four versions of the album had sold out entirely and was under additional printing; release for the Normal A versions of the album were postponed to February 21, and the Normal B and Limited A & B versions of the album were postponed to February 26.[8]

On February 25, Orbits broke the previous record for number of pre-votes for The Show by gathering a total of 3,677,262 votes.[9] It was also revealed that the Normal B and Limited A & B versions would be postponed again to March 6,[10] but a later update after consulting with the new distributor, Kakao M, revealed that Limited A & B would stop production entirely.[11]

Kakao M underestimated album sales, thus causing the albums to be sold out very quickly. They also uploaded the album to a completely new spotify account which made it difficult for fans to find the album. Those issues reduce their chances of winning on music shows since it depends on their albums sold, streams etc.

On November 1, Jaden Jeong confirmed that the release of LOONA the Ballad was cancelled; but, a Japanese debut was still possible.[12]
