ArtistMYSTIC STORY
Tsuki
Tsuki, born Fukutomi Tsuki (福富つき), moves through Billlie with the kind of facial control and rhythmic detail that turns a comeback stage into a replay magnet. Since debuting under MYSTIC STORY in 2021, the Japanese performer has helped define the group's darker, lore-driven edge while building her own lane across music, studio OST work, and fast-rising variety bookings. Her 2026 panel role on Channel A's Heart Signal 5 widened that profile again, adding mainstream television visibility to the same precision fans already know from Billlie releases alongside Suhyeon, Siyoon, Moon Sua, Haram, Haruna, and Sheon.
