KAMITSUBAKI STUDIO is actively expanding its international charity presence, releasing new music from its cross-reality unit Kuusou, and sending its virtual singers into overseas live markets.
KAMITSUBAKI STUDIO has been building its international profile through charity streaming and overseas live performances. In June and July 2026, the studio participated in VTuber Summer Slam 2026, a U.S.-organized charity event by Gamers Outreach, for the first time. Four affiliated artists-RIM, KOKO, KAKYOIN, and HINAGESHI-streamed Overcooked! 2 on the studio's YouTube channel, raising 1 million yen for Gamers Outreach to provide gaming experiences to hospitalized children. The stream was conducted primarily in English with Japanese translation, marking a deliberate bridge between the studio's domestic fanbase and a global fundraising effort.
On the music front, the studio's virtual music unit Kuusou released its debut EP 'CYAN' on June 17, 2026, featuring five tracks produced by HIDEYA KOJIMA with lyrics by YUC'e, Pon, and NEFFY. The unit, formed by virtual singer CIEL and singer-songwriter Sooda, held its first solo virtual mini live 'Kuusou Palette' on June 27, streamed free on YouTube with paid multi-angle tickets on Z-aN. The live included first performances of songs from the EP and a new song not on it.
KAMITSUBAKI STUDIO also expanded its virtual singer operations into overseas live markets. Virtual singer Kaf performed a 29-song set in Hong Kong on May 30, 2026, with no streaming available, based on her March 2026 one-man live. Virtual singer Isekai Joucho recreated her 2021 online debut concert at Zepp Haneda on May 2, 2026, faithful to the original setlist and staging. Tsumi Juubatsu, a performer from the Shoujo Kakumei Keikaku unit, returned to the event circuit at GOLD DISC on July 11 after an eight-month hiatus.
