Hololive Council and Promise Members Explained
Five cosmic idols debuted on the same chaotic day in 2021, and three of them are already gone. That is the beautiful, heartbreaking saga of Hololive Council squeezed into one sentence, and honestly it still guts us! This was the second English generation from Hololive, and it landed with a slick cosmic-council concept that fans went absolutely feral over. Space, Time, Civilization, Nature, and Chaos, all bundled into five brand new idols. In this guide we walk you through every Hololive Council member, explain how the group quietly rebranded into Hololive Promise, and cover the graduations that broke our timelines. We love this gen, so let’s get into the whole messy, gorgeous story!
Hololive Council is one of those debuts that fans still talk about like it happened last week. If you want the bigger picture on the agency itself, check out our breakdown of Hololive Productions and the rise of the VTuber first, then come back here for the deep cut.
What Is Hololive Council?
Hololive Council is the second generation of Hololive English, and it debuted on August 22, 2021. The girls came out in a relay format, meaning each one got her own solo debut stream back to back over roughly a two-day window. It was chaos in the best way. Fans were hopping between channels for hours, timezone be damned, trying to catch every single first impression live.
The concept tied the whole group together with a genuinely cool bit of lore. Each member represents one of the great “Concepts” that keep reality running. You have got Space, Time, Civilization, Nature, and Chaos. On top of that, the members were framed as a literal council that governs these forces, which is exactly where the name comes from. It is corny and we adore it with our entire hearts.
Coming right after the record-shattering success of HoloEN Gen 1 (the Myth girls like Gawr Gura and Amelia Watson), Council had impossibly big shoes to fill. Gura had already become the most-subscribed VTuber on the planet, so the pressure was insane. Somehow the new gen pulled it off anyway. Within days the whole group was racking up subscribers at a wild pace, and the fanbase locked in fast and hard.
Meet the Hololive Council Members
Let’s introduce the original Hololive council members one by one, because each of these five brought something completely different to the table.

Tsukumo Sana was the Speaker of Space. Her whole vibe was cosmic and a little aloof, which fit perfectly for someone whose domain is not just our universe but every other dimension too. She had this warm, goofy, chaotic-artist energy that clashed hilariously with the grand “I am the embodiment of space” lore, and fans ate it up. She was also a monster at art and drew live on stream constantly.
Ceres Fauna was the Keeper of Nature, aka the Kirin who wants to heal the planet. Fauna became legendary for her soft ASMR streams, that iconic “kirakira” sparkle noise, and mothering her chat while also being unexpectedly menacing and unhinged when the mood struck. The fauna vtuber energy was pure comfort with a chaotic gremlin streak hiding right underneath, and that combo made her one of the most-watched members of the gen.
Ouro Kronii is the Warden of Time. Deep voice, cool exterior, and an absolutely feral sense of humor once she warms up. Kronii blew past 200,000 subscribers the day after debut and just kept climbing, cruising past half a million within a couple of months. Her deadpan delivery and villain-arc bits made her an instant fan favorite.
Nanashi Mumei is the Guardian of Civilization, an owl carrying the weight of all human progress on her tiny shoulders. The mumei vtuber persona swung between adorable birdbrain and genuinely poetic, sometimes in the same sentence, and her singing and art blew people away every single time. Mumei crossed a million subscribers and became one of the most beloved members of the whole gen.
Hakos Baelz is the Chairperson of the council and the living embodiment of Chaos. She looks like a mouse, complete with a cheese choker and a little mousetrap stuck to her ear, and she runs at a thousand miles an hour. Bae is high energy, a phenomenal dancer with a real dance background, and the social glue that held a ton of the group collabs together.
IRyS and the Road to Hololive Promise
Here is where it gets slightly confusing, so stick with us. Before Council even debuted, Hololive English dropped a VSinger named IRyS on July 11, 2021, under a separate banner called Project: HOPE. IRyS was not technically part of Council. She was her own thing, the very first dedicated singer of HoloEN.
Her design was gorgeous and noticeably different from the rest of the roster, because she was drawn by redjuice of supercell fame (the artist behind a mountain of EGOIST and Guilty Crown art). Lore wise, IRyS is a Nephilim, half angel and half demon, who showed up to deliver hope to a world drowning in despair. Dramatic! We love her for it. She also went through a mid-2022 design and rigging upgrade that fans still gush about.
Even though IRyS technically debuted solo, she got glued to Council almost immediately. She collabed with them constantly, hung out with them nonstop, and fans started lumping the six of them together under the affectionate nickname “CouncilRyS.” It was basically a done deal that IRyS was the unofficial sixth member long before anything became official on paper.
How Council Became Hololive Promise
So how did we actually get Hololive Promise? It comes down to a graduation and a rebrand.

In July 2022, Tsukumo Sana graduated from Hololive, leaving Council with four members. That was the first big gut punch for this gen. Sana wanted to focus on her own creative path outside the agency, and while fans were crushed, she got a proper heartfelt sendoff instead of a sudden exit.
Then, on October 9, 2023, Hololive made it official. The four remaining Council girls (Fauna, Kronii, Mumei, and Baelz) merged with IRyS from Project: HOPE to form a single new unit called Hololive English Promise. This new group absorbed both of the old banners and became the official, unified HoloEN second generation. So when people say hololive promise, they mean these five together as one squad, no asterisks needed.
The rebrand made total sense. These five were already inseparable, so slapping one name on them just matched what fans were watching every day anyway. Promise came with fresh new outfits, a group identity, and a renewed feeling that this was one family instead of two loosely connected projects. For a stretch there, Hololive Promise genuinely felt unstoppable, and the collab chemistry between them was some of the best in the entire agency.
Fauna VTuber and the Graduation That Shook EN
Then came the news nobody wanted. In late 2024, it was announced that Ceres Fauna would graduate, with her final stream landing in early January 2025. The reason cited was differences with management, and that news hit the community like a truck.
Fauna was a cornerstone of this gen, no exaggeration. She hosted some of the most consistent, cozy, comfort-heavy streams in all of Hololive, and she was famous for showing up to support her friends’ streams constantly. The fauna vtuber graduation felt especially brutal because it seemed to come out of nowhere, and the “differences with management” framing had fans reading between every single line and refreshing every social feed for scraps of context.
Her graduation stream was an absolute tearjerker, and the whole EN branch showed up in spirit to send her off. Fans flooded social media with fan art, thank-you messages, and clip compilations for days afterward. If you want the full emotional play by play, our Fauna face reveal and graduation story breakdown covers the fallout in detail. Losing her was the moment a lot of people realized Promise was not going to stay whole forever, and it stung.
Mumei VTuber and the 2025 Goodbyes
Barely a few months after Fauna, the gen took another devastating hit. In late March 2025, Hololive announced that Nanashi Mumei would graduate at the end of April 2025, right around her three-and-a-half-year anniversary. Two goodbyes in one gen inside a single winter-to-spring stretch felt almost unfair.
The mumei vtuber departure came with two big reasons. First, chronic health problems, including a persistent cough and throat trouble that had been messing with her voice and her ability to stream reliably. For a member so tied to singing and live performances, that one really stung to hear. Second, she pointed to internal misalignment with the company, echoing some of the same energy fans had picked up on around Fauna’s exit.
Mumei leaving meant that within the span of about four months, Promise went from five members down to three. That is a heavy, heavy blow for any generation, and it left the fandom genuinely shaken about the direction of HoloEN as a whole. Her farewell was packed with the same poetry, warmth, and quiet wisdom that made her so special in the first place, and her final singing moments wrecked everyone.
As of now, the surviving members of Hololive Promise are Ouro Kronii and Hakos Baelz, still streaming and still bringing the chaos and the deadpan comedy we all signed up for. The gen is smaller than it used to be, but those two are absolutely keeping the flame alive, and their bond hits different after everything Promise has been through.
Face Reveal and Past Life Gossip
You knew we were going to go here. With any Hololive gen, fans immediately start hunting for past lives and face reveal clues, and Council is no exception. Half the fun of a new debut is the detective work that kicks off within hours.
Hololive has famously strict rules about talents keeping their old identities separate, so nobody in this gen has done an official face reveal. That has never stopped the sleuths, though! The fan consensus is that several Council members had established indie or content creator careers before joining, and the community loves connecting voice clips, art styles, and inside jokes back to earlier personas. Fauna’s polished ASMR skills and Kronii’s instantly recognizable voice in particular have fueled endless past life threads that still get bumped today.
The general vibe among longtime fans is that these girls were seasoned pros before they ever put on the Hololive skins, which is a big part of why the gen felt so shockingly polished right out of the gate. If digging into VTuber identities is your thing, our what is a VTuber guide explains why these reveals are such a massive deal in this fandom in the first place.
We will always respect that these are real people who chose their privacy, full stop. But the gossip is half the fun of being in this community, and Council gives fans plenty to theorize about for years to come.
Frequently Asked Questions

Which Hololive Promise members have graduated?
Tsukumo Sana graduated in July 2022. Ceres Fauna graduated in early January 2025, and Nanashi Mumei graduated at the end of April 2025. That leaves Ouro Kronii and Hakos Baelz as the active members of Hololive Promise.
Why did Fauna and Mumei graduate?
Fauna’s graduation was tied to differences with management. Mumei cited a mix of chronic health issues affecting her voice along with internal misalignment at the company. Both departures happened within a few months of each other in early 2025.
Did any Hololive Council members reveal their faces?
No official face reveals here. Hololive keeps talents’ past identities under wraps, so nothing has been made official. Still, the fan consensus is that several members had prior content careers, and past life theories are a constant topic in the community.
