YUNA
CSR · Main Dancer · Vocalist
Profile
YUNA (Iimura Yuna) is a Japanese member of CSR and contributes to the group’s dance and vocal performances. She was born in Ibaraki Prefecture and previously took part in Japan’s Harajuku DREAMMATE before debuting with CSR.
Her background in Japan gives CSR a natural connection to Japanese-language promotions. The group expanded its activities there with the 2024 mini album L’heure Bleue, including the Japanese release Higher, and subsequent fan events.
In October 2025, Yuna and fellow CSR member Yeham launched a separate project called Red Soda Circle, adopting the names Rina and Haru. That project exists alongside her ongoing work with CSR, which resumed Korean releases in March 2026.
