XION is a vocalist and the youngest member of ONEUS. He is part of the group’s active 2026 lineup and released the solo single “Camellia” in May 2025.

In February 2026, all five ONEUS members signed with B.Wave Entertainment, which also acquired the ONEUS-related IP from RBW. Group awards and group-wide achievements are kept on the main ONEUS page rather than repeated as personal honors.
