Good question. I couldn’t find any definitive, credible evidence that Kyuotto just rebranded and kept streaming under a totally new persona. Here’s a breakdown of what the community does know (and what is still speculative), plus possible scenarios:
What We Know About Kyuotto’s Disappearance / Hiatus
YouTube Presence
Her YouTube channel still exists: it’s mostly just BGM / music / audio now, with her old VODs apparently removed / privated.
YouTube
Drama & Harassment
There was a lot of backlash in the past about her “loli succubus” model.
Reddit
+1
On Reddit, some defended her, saying her design itself isn’t malicious and criticizing the “anti-loli” crowd.
Reddit
There is a “drama archive” listing on a community forum, which claims she locked her accounts and may have “given up on being a VTuber” at one point.
Varis.Forum
Design Changes
There’s a video titled “Kyuotto is changing her design”.
YouTube
This suggests she at least planned or considered a rebrand / model update, not necessarily a full disappearance.
Social Media
Her Twitter / X account: there is a relatively recent tweet (2024) from Aurisa Aurora / @kyuotto, identifying herself as the same person (“Vtuber and illustrator”).
X (formerly Twitter)
This means she didn’t completely vanish — she’s still present in some capacity, at least on X / social.
No Solid Alternate Identity
I found no confirmed “she is now streaming under new name / avatar” thread with receipts.
There’s no major VTuber listed who is publicly confirmed to be her “new persona” that matches all her old lore + style + voice.
Possible Theories / Scenarios
Given the above, here are some plausible theories (unproven) about what might have happened:
Semi-Retirement / Hiatus: She may have just stepped away from active streaming due to burnout, harassment, or motivation loss, keeping only her BGM / YouTube presence alive because she still cares about the art / music side.
Model Rework / Rebrand: The “changing her design” video suggests she might have planned a rebrand but never fully launched it (or did, but quietly). Maybe she intended to drop the “loli succubus” model to avoid drama, but didn’t follow through—or didn’t make it public.
Low-Key Activity: She could be creating content privately / semi-privately (e.g., for patrons, or a smaller circle), but not streaming anymore publicly. Some VTubers do that after controversies or when stepping back.
Abandonment of VTuber Persona: It’s possible she decided to retire the VTuber side but still keeps her “creative personality” alive through her illustration work and her social media, without actively streaming.
Why It's Hard to Confirm Anything
The VTuber community around indie creators is often fragmented, and many changes happen off-platform (Discord, Patreon) where not everything is publicly documented.
If she did rebrand under a new name, she might have purposefully kept it unlinked to “Kyuotto” to avoid reopening old drama / attracting harassment.
Old accounts being locked / privated makes historical tracking difficult.
Conclusion: Based on what’s available, the most likely scenario is that Kyuotto went on semi-hiatus / low-key rather than fully abandoning everything or dramatically rebranding into a completely new VTuber. She hasn’t disappeared entirely, but her public VTuber activity has definitely diminished, and she may have pulled back because of the controversy.
If you like, I can dig into archived social media (using Wayback Machine etc.) and try to see if there's any hidden rebranding or resurgence. Do you want me to do that?
