Keena
Keena (키나), born Song Yu-ni, is the continuity point that kept FIFTY FIFTY from turning into a complete restart. She debuted with the original lineup under ATTRAKT in 2022, contributed to the group's early identity through her rap tone and writing presence, and then became the member who bridged the Cupid era into the five-member rebuild.
That makes her role bigger than a standard rapper slot. In practical terms, Keena is the member who ties the group's breakout global moment to its current structure with Chanelle Moon, Yewon, Hana, and Athena. Her presence gave the relaunch a real line of continuity, not just brand recycling, and that is why her page needs to be read as both original-member history and present-era leadership.
The credit stack reflects that two-part story. She is attached to the debut-phase releases that first pushed FIFTY FIFTY into the market, then to the 2024 comeback material that reset the group for a new cycle. HITKULTR follows both sides of that timeline instead of flattening her into a single viral-song footnote.
