RIOT MUSIC Inc. has announced that three new artists — Denshinbashira-chan, Miyajima Leciel, and Kasaya Kuguru — will debut under its VSinger label “Mugensho Record.” The trio’s first streams will run on Monday, June 1, 2026 starting at 7:00 PM, with each artist taking the spotlight in hourly slots across their respective YouTube channels.

Mugensho Record Triples Up With Simultaneous Debuts, Expanding the Label’s Roster

Mugensho Record is a VSinger label operated by RIOT MUSIC Inc. The label name carries the meaning that the label is “the origin point” of virtual music spreading “countlessly,” and that the songs of “rough gems” — artists with countless possibilities — come together to form a “chant.” This three-artist simultaneous debut is a major move that directly expands the label’s roster.

RIOT MUSIC is a music agency under Brave group that runs several music-centered projects, including the VSinger label Mugensho Record, the VTuber support project “RIONECTION,” and the VRChat activity support service “AdHoc.” In addition to new signings via its standing virtual artist auditions, this label-level three-debut simultaneously is an impactful announcement even within Brave group as a whole.

Denshinbashira-chan: A Blue-and-White Performer Who Found Song Through Dance

The first artist, Denshinbashira-chan (DENSHINBASHIRA-CHAN), was originally shy and uncomfortable standing out, but discovered the joy of performing in front of audiences through yosakoi and dance — which she started by imitating her older sister. As for singing, which she once disliked, she came to love it thanks to a voice training teacher and the warm words of friends who praised her singing.

Her motivation for applying to RIOT MUSIC’s audition was the feeling that “there is still so much I have not done in my life — I cannot end like this.” Her stylists are Riichu and rariemonn. Activities are planned across multiple SNS platforms including X and TikTok, and a key point of interest will be what kind of expression she shows as a dance-rooted performer.

Miyajima Leciel and Kasaya Kuguru: Two Performers With Their Own Stories

The second artist, Miyajima Leciel (MIYAJIMA LECIEL), became interested in music after listening to anime songs in childhood, and began online music activities after being praised for singing in front of friends and family. She passed the audition driven by the wish to “make more people happy with my songs.” Her stylists are Mucha and Shibao Kanata.

The third artist, Kasaya Kuguru (KASAYA KUGURU), has a unique world-building character setting: she was raised being told by the owner of a doll repair shop, “You were originally a doll — I breathed life into you.” She joined RIOT MUSIC out of a desire to direct the songs and expression she had previously kept to herself toward the people dear to her and toward those she has yet to meet. Her debut name is borrowed from the cherished shop “Kasaya Doll Repair Shop.” Her stylist is Tekitou Midori.

What’s Next: Three Consecutive First Streams Across 3 Hours From 7 PM on June 1

The first-stream schedule runs as follows on Monday, June 1, 2026: 19:00 Denshinbashira-chan, 20:00 Miyajima Leciel, and 21:00 Kasaya Kuguru — each on their respective YouTube channels, back-to-back. Because three artists stream their debuts consecutively, the window between 7 PM and roughly 10 PM that night will be must-watch time for Mugensho Record fans.

Post-debut activities, music releases, and any potential joint projects have not yet been announced, so future updates are expected. The standing audition continues, so further additions to the label’s roster also remain worth watching.

Outlook

A three-artist simultaneous debut from a VSinger label is, within the recent VTuber and VSinger scene, an effective move that quickly raises the label’s presence. Each member is given a distinct backstory, suggesting the intent to strengthen the label’s identity as a world view-sharing roster — not merely a collection of singers. How far RIOT MUSIC under Brave group can expand its music-axis presence will likely be measured against the three consecutive debut streams on June 1, making that night a pivotal moment for the label’s future evaluation.
