Sion
Oh Si-on (오시온), born May 11, 2002 in Mokpo, South Korea, is the leader and lead vocalist of NCT WISH (엔시티 위시), the sixth and final sub-unit of SM Entertainment's global K-pop collective NCT. Standing 178.9 cm tall with blood type O and an INTJ-A personality, Sion was scouted by SM via Instagram DM and trained with the label for four years before being publicly revealed as a future NCT member in June 2023 -- one of two members pre-selected as SM Rookies before NCT Universe: LASTART determined the final lineup. His vocal control and natural leadership presence defined the group's identity from the start.
NCT WISH debuted on February 28, 2024 with the single "Wish," launching Sion as the anchor of a group operating primarily from Japan with a five-member Japanese roster around him. The group continued with poppop (April 14, 2025) and COLOR (September 1, 2025), ahead of their debut full-length album Ode To Love (April 20, 2026). His hobbies include seeking out new music, reading, watching anime and dramas, and bowling. He cites EXO's Kai as his primary role model, drawn to his ability to command a stage without apparent effort.
