LOCUS-X's own archive dates Rozy's debut to December 2020

The persona

Rozy presents on Instagram as "Korea's First Virtual Influencer," a claim made on her own account, checked 16 September 2026, which shows a platform-reported 160,000 followers and a contact link to locus-x.com. That studio's own press archive lists a dated item, translated from Korean, titled "SIDUS studio X unveils virtual influencer ROZY," dated 30 December 2020, naming SIDUS studio X, a production unit tied to the Korean agency Sidus HQ, as her original operator.

What the documents establish

The same press archive lists a later item, dated 8 December 2021 and translated as "NAVER Webtoon acquires the company holding virtual human ROZY for 23.4 billion won," indicating a change of ownership roughly a year after her debut. This site has read the archive's own headline listing rather than the underlying news article, so the acquisition detail is reported here as what the studio's own page states occurred, not as independently confirmed reporting. The studio's current "about" page names Seungyup Baik as chief executive and states a mission "to become the No. 1 virtual entertainment group," with Rozy listed alongside three newer virtual artists, Hogonheil, Ryu-id and Project G. Neither Sidus HQ's own materials nor a standalone Sidus Studio X site could be located during this research to independently corroborate the earlier name.

Character versus company

Rozy's Instagram content, including her music and brand appearances, is produced by whichever corporate entity currently operates the account, first identified in the studio's own record as SIDUS studio X and later, per the same page, transferred through a Naver Webtoon acquisition; her account does not disclose which entity currently manages her day to day. The site's own about page, not any post from Rozy, is the source for LOCUS-X's leadership and mission.

What to watch

Because no separate Sidus Studio X site could be verified directly, a reader should treat that studio's original structure and its relationship to Sidus HQ as established only through LOCUS-X's own later summary of its history, not through the original operator's own materials; this is a gap this review could not close. Whether LOCUS-X is the direct legal successor to SIDUS studio X, or a separately branded unit under the Naver Webtoon-linked ownership, is not stated on the pages reviewed.

• Is LOCUS-X the direct corporate successor to SIDUS studio X, or a newly branded entity?
• What did the 23.4 billion won Naver Webtoon transaction actually cover, per any primary filing?
• How has Rozy's platform-reported follower count changed since her 2020 debut?

The confirmed throughline is institutional rather than personal: a named studio introduced Rozy in December 2020, a reported acquisition moved her holding company about a year later, and her current operator's own site, not the character's feed, is the only available record of that chain.
