ELENA (Elena Kwon, also known as Kwon Ye-na) is an American member of TUIDE, born April 11, 2008. She debuted with the group’s first EP, TUNE & PLAY, on August 24, 2026. Her expressive vocals and fluent, smooth dance style are among the characteristics her fellow members have emphasized.

In a Teen Vogue interview, SEAH described ELENA’s voice as elegant and her movements as fluid. ELENA herself discussed reading listeners’ reactions to performances and using constructive feedback to improve. She also identified singer TYLA as a dream collaborator, explaining that she had enjoyed performing TYLA’s songs during training.

During TUIDE’s August showcase, ELENA discussed the song Echo, which incorporates a melodic element from Janet Jackson’s All for You. Her comments concerned the group’s recorded track and its musical influence, not an ELENA solo cover or independent release.

ELENA participated in the group’s August 7 pre-debut GRLS performance and later the full debut activities for SUN KISS. Her personal musical influences offer a distinctive window into TUIDE’s international sound.
