As immersive content and deliberate IP worldbuilding gain traction in Japan’s virtual‑streamer scene, Brave group — the operator behind ぶいすぽっ！(VSPO!), HIMEHINA and Neo‑Porte — has rolled out a new initiative through its next‑generation label, BEverse.
On April 16, Brave group revealed the debut of GΔ59 (pronounced Jigoku) as the first installment of its creative program Tokyo Virtual (東京仮想). The name merges the mathematical symbol Δ (delta, signaling change) with the prime number 59 to evoke the unknown at the edge of transformation.
The quartet includes Yoiyami Mee (宵闇めぇ), Chiaki Luna (千白るな), Amagami Konkon (甘噛こんこん) and Tsumetogi Rin (爪伽リン). Their individual X accounts are @mee_yoiyami, @luna_chiaki, @konkon_amagami and @rin_tsumetogi. Character designs, group and solo promotional videos, the debut single and details of the debut stream will be released in stages.
Tokyo Virtual centers on alternate‑reality game (ARG) mechanics that fold the real world into the narrative. Viewers are expected to assemble clues scattered across streams, social posts, the official site and Discord to piece together the story. The project taps many creators from horror and occult circles and launched a prologue titled Rebirth: A Request of 花葬. At the time GΔ59 was announced, the teaser site briefly redirected to a fictional underground idol act, Chu‑Chu‑Trick, framing a storyline in which one member mysteriously disappears and featuring unsettling entries and ominous photos on an Ameba blog.
The debut stream will be simulcast in early May on TikTok LIVE and YouTube, and it will coincide with Tokyo Virtual’s first alternate‑reality broadcast (代替現実配信), the project’s signature interactive format. Global Growth (GGTK) — one of Japan’s largest creator networks and operator of GGTK Tokyo Studio 1, the country’s first studio dedicated to TikTok LIVE — will handle TikTok Live operations. GGTK says it manages more than 5,500 creators in Japan and has surpassed a cumulative gifting total of ¥20 billion (about $134 million).
BEverse, founded by Brave group in April 2024 as a metaverse‑focused content label, has concentrated on immersive game projects such as the Roblox title “Ao Oni: Nightmare” (a collaboration with LiTMUS) and the Fortnite title “The Forest of Fear: Liar In The Dark.” BEverse reported that “Ao Oni: Nightmare” averaged roughly 1 million plays per week, with only about 6% of that traffic coming from Japan — a sign that international users dominated. GΔ59 represents a strategic shift for BEverse from adapting game IP toward creating original virtual talent and idol IP.
Beyond character‑first activity, the virtual‑streamer industry has increasingly offered worlds and narratives as services — an approach validated by mystery projects that erode daily reality, like Project:;COLD. Brave group has been accelerating its global IP push: in May 2025 it reached a capital and business alliance with South Korea’s Kakao and transferred part of its U.S. operations to a newly formed company that same year. By launching the project from both TikTok and YouTube hubs and structuring it around ARG participation, Brave group’s model could shape future competition and collaboration between Japanese IP and the burgeoning K‑virtual market.{vi21}
