The global stage just got a little brighter with the official arrival of cosmosy, a bold new girl group launching their debut single “Lucky=One” to worldwide audiences.

The four-member group composed of all Japanese members himesha, de_hana, kamión, and a’mei makes its debut under Sony Music Entertainment Korea and NTT docomo Studio & Live, with creative direction by SINXITY, the visionary behind BLACKPINK and other top-tier K-pop artists like LeeHi, WINNER and KATIE

Blending dreamy tropical house textures with soft pop melodies, “Lucky=One” is sung entirely in English, embracing themes of serendipity, connection, and youthful optimism. The release follows their buzzed-about pre-debut track “zigy=zigy,” which amassed over 10 million views in just two weeks. The new “Lucky=One” music video crossed the 1 million-view mark within its first 24 hours and now boasts 8.4 million views to date.

Inspired by the cosmos flower, a symbol of girlhood and youth, cosmosy aims to embody "the cosmos of youth" with a fusion of J-pop experimentalism, K-pop polish, and Gen Z authenticity. Their hybrid aesthetic merges late-‘90s Y2K charm with the future-facing creativity of today’s youngest global generation

Currently based in Korea, cosmosy promoted “Lucky=One” with a successful pop-up event in Seoul and performances on major K-pop music shows like KBS Music Bank, SBS Inkigayo, and Mcountdown. With an all-English debut single and a multilingual, multinational strategy, cosmosy is positioned as one of the most globally-minded girl group debuts of 2025
