Jaylou Boc Feliciano is listed as the youngest member of OONA. Before joining the group, she was already connected to entertainment through TV commercial modeling, auditions, and public appearances, including BPOP Idol Search, the 2024 Star Hunt audition, and the EXpecially For You segment on It’s Showtime.
Jaylou is also described as someone who can play the guitar and has an ambivert personality. Her profile-source details mention that she is a night owl and likes coffee. Since her only clearly listed role so far is youngest member, it is best to avoid giving her a fixed vocal, dance, or rap position until OONA or management confirms it.
