Before debut

ONEUS did not arrive as six anonymous faces. Training projects, evaluation programs and public stages created uneven amounts of pre-debut footage. This file uses that record as context without forcing Xion to remain the person an edited competition introduced.

Debut and the six-member catalog

LIGHT US and “Valkyrie” establish the professional starting line. Ravn’s later departure does not delete the original recordings. Xion belongs to both the six-member history and the current five-member group, with the transition dated rather than blurred.

Performance identity

Xion is the vocalist, actor and youngest member with increasingly deliberate camera control. The useful evidence is how that quality changes across LIT, LUNA, Same Scent, Baila Conmigo, X and Grenade. A fixed position can identify responsibility; it cannot replace listening to breath, phrasing, rhythm and handoffs.

Current status: The five-member era

After October 2022, ONEUS continued as Seoho, Leedo, Keonhee, Hwanwoong and Xion. The group re-recorded selected earlier songs as Penta versions, making the change audible and explicitly labeled instead of pretending only one master chronology exists.

The company transition

All five members ended exclusive RBW contracts in February 2026 while preserving the group name. Official notices later identified B.Wave in the IP and service transition. Xion therefore continues one ONEUS career across companies, not a newly debuted identity.

Seoho’s service window

During Seoho’s active-duty service, Xion helped carry releases and performances in the smaller configuration. Seoho’s August 16, 2026 discharge restores the active five, while the four-member screen record remains accurately labeled.

Artist routing rule

Xion has verified individual original work within the official ONEUS release ecosystem, so this same canonical page can serve both member and Artist discovery. A second biography would split dates, images and credits for one person.

X and the exact React

The “X” React follows exact official upload 7tEgWyYB8YE. It links Xion only where participation is visible or otherwise confirmed. Seoho remains part of the group chronology but is not inserted into a four-member MV relationship merely because he returned later.

International fan guide

Use official ONEUS, Japanese-site and agency notices first. Company transfers often leave old handles, copyright lines and storefront pages active at different speeds. The page preserves dates and sources so international fans can follow the transition without treating every stale footer as a new scandal.

RaeRae take

The interesting part of Xion is not a superlative. It is the way a recognizable choice survives changes in concept, lineup and company. ONEUS concepts are loud enough to hide a person who only performs the mood board; Xion is worth tracking when the decision remains identifiable underneath it.

What to watch next

The first full five-member work after Seoho’s discharge should clarify updated line balance, credits and live arrangement. This page will add exact releases and verified status changes without cloning the human into separate member and Artist files.
