Rapper Kamui and TikToker Poser Shiraishi have launched RAF Studio, a streaming channel on Twitch and YouTube that reacts to new hip-hop releases, hosts talk and music production sessions with rappers, and provides commentary on the RAPSTAR audition project. The channel began after a collaborative stream in June 2025 and has grown to include an ABEMA show, Kamui's HYPE THE HOPE.
RAF Studio, operated by rapper Kamui and TikToker Poser Shiraishi, streams reactions to new hip-hop music and MVs on Twitch, with clips posted to YouTube. The channel also runs the project IN THE BOOTH, where rappers and producers are invited for talks and music production, and occasionally hosts game events with rappers. Since 2025, they have provided commentary on the RAPSTAR audition content from a rapper's perspective. Kamui's own show, Kamui's HYPE THE HOPE, airs on ABEMA. The channel's origin traces to Kamui's elimination from RAPSTAR in 2024, referenced in his song Usagi to Kame, which also reveals that ABEMA president Fujita DM'd him about a new show. With RAPSTAR 2026 now in the judging period, RAF Studio continues to discuss application beats and the project's future.
