Brave Group Launches New VTuber Group GΔ59 Under Tokyo Kasou Project
Brave Group's content label BEverse announced the first project under its creative initiative Tokyo Kasou: a new VTuber group called GΔ59, pronounced "Jigoku." The group consists of four members: Yoiyami Mee, Chiaki Luna, Amagami Konkon, and Tsumetogi Rin. The name combines the mathematical delta symbol (Δ), meaning change, with the prime number 59, intended to represent the unknown beyond transformation. The group's story will unfold through puzzles and clues scattered across social media, websites, and Discord. Character designs, group promotional videos, individual teasers, and debut music information will be released gradually. A debut livestream on TikTok LIVE and YouTube is planned for early May, along with the first "alternate reality" stream, an interactive format unique to Tokyo Kasou. TikTok operations and growth strategy for GΔ59 will be handled by Global Growth (GGTK), a company with experience in TikTok live commerce and creator management. BEverse has previously produced immersive titles such as Roblox's "Ao Oni Nightmare" and Fortnite's "Horror Forest - Liar In The Dark."
