Miori Celesta: a singer who also works inside the recording
Miori Celesta is a virtual singer whose catalogue connects original songs, collaborative covers and the detailed work of preparing recorded vocals. Her releases credit her not only as a performer but, depending on the project, as a lyricist, topline writer, vocal editor, mixer or video maker. Those are different jobs: a vocal performance is not automatically a songwriting credit, and editing a recording is not the same as producing its instrumental.
Her music offers a useful route through several years of VTuber creation. The early collaboration Wonderland, the illustrated Chapter, the full-length Ride the Day, and later songs inspired by game characters show changes in both the scale of the productions and her responsibilities. The credits make those changes visible without reducing her career to a list of recent livestreams.
Current activity: the character is on hiatus
At the time of our October 15, 2026 review, her official YouTube channel description says she is unlikely to return to this character in the near future and does not expect to stream as Miori anytime soon. It also says she is releasing music through a separate account dedicated to music. This profile therefore describes the Miori character as on hiatus. The statement does not supply a confirmed return date or establish a permanent retirement date.
Her existing recordings remain part of this character's public history. Readers arriving for a song should distinguish that archive from an announcement of new Miori broadcasts. The channel statement does not identify the other music account, so it is not used here to attach another identity or catalogue to her.
Early originals: Wonderland and Chapter
The May 2021 release Wonderland, featuring Zen Gunawan, credits Miori with vocals, mixing and video, and Zen with vocals and guitar. The accompanying description traces the song back to an earlier collaboration. It is an early example of a project in which Miori participated on both sides of the microphone, helping turn a shared musical idea into a finished audiovisual release.
Chapter, released in July 2021, separates those responsibilities differently. Tephe receives the music credit; Miori is credited for vocals, lyrics and vocal editing, with an additional lyrics credit for Itovero and mixing by Velvet. Its visual team includes sprite and chibi illustration, walking animation and video work. The result places her character inside an illustrated fantasy presentation while preserving the distinction between the song, vocal recording and visual production teams.
Together, these releases explain why describing her only as a singer leaves something out. They also show why it would be inaccurate to label every early original as entirely self-produced: collaborators have specific, named contributions.
Ride the Day: a full-length song with a separate production team
In March 2022, Ride the Day was introduced on her channel as her first full-length original. That wording concerns the full-length format; it should not erase the earlier original releases.
The credits assign production and songwriting to Lost., vocals and vocal tuning/timing to Miori, and the vocal mix to Uzuki Tomoya. Illustration, Live2D and video have separate credits as well. For a listener discovering her work, this is a clear example of a VTuber song built by a small creative team rather than a single person doing every task. For someone interested in production, it also identifies her vocal preparation work without attributing the composition or final vocal mix to her.
Covers and collaboration: Zero with Chisaka Airi
The October 2023 cover of NewJeans' Zero, published by Chisaka Airi, features both singers. Miori also receives the tuning and timing credit; Tsukkun is credited for mixing, イマフク for illustration and Negai Lab for video.
This collaboration connects her own catalogue to work on another creator's channel. It is a cover of a NewJeans song, not a Miori original, and a shared recording does not establish shared agency membership. Airi's profile supplies the other performer's musical context, while the original upload preserves the exact project credits.
Game-character songs: Fan the Flames and Roaring Storm
Fan the Flames, released in October 2024, builds a song around Rappa from Honkai: Star Rail. The description explicitly discloses sponsorship by the game. Miori is credited with vocals, topline, lyrics and vocal tuning/timing; Flay! handles production, mixing and mastering. Finé, Yusa and RexHernan22 receive the illustration, Live2D and music-video credits respectively.
The July 2025 Roaring Storm follows a similar collaborative structure for Ju Fufu from Zenless Zone Zero. Its description also discloses game sponsorship. Miori again receives the vocal, topline, lyrics and tuning/timing credits, with Flay! on production and mix/master, Toraki211 on illustration, Yusa on Live2D and Hanwyaa on the video and thumbnail.
These projects show character-focused songwriting alongside vocal performance. Sponsorship explains their commercial context; it does not, by itself, establish that either recording is part of an official in-game soundtrack. Their release dates likewise describe the videos, rather than every later distribution date on a music service.
A listening route through the catalogue
- May–July 2021: Wonderland and Chapter introduce collaborative originals, vocal editing and illustrated music videos.
- March 2022: Ride the Day expands the full-length format with a distinct songwriting and production team.
- October 2023: Zero pairs her performance and vocal editing with Airi's cover catalogue.
- October 2024: Fan the Flames connects her songwriting and recording work to Rappa, with disclosed sponsorship.
- July 2025: Roaring Storm extends that game-character song format to Ju Fufu.
- October 2026 observation: the channel describes a pause in activity as Miori; no return date is confirmed.
Start with Chapter for the illustrated fantasy presentation, Ride the Day for the full-length original, or the two game-character songs for the later topline-writing credits. The guide to VTuber content formats explains how original music, covers and livestreams differ; the activity-status guide explains why an accessible archive and an active character are separate questions.
