Synthesized from 19 Yomimono stories · updated 9h ago

KAMITSUBAKI STUDIO's 2026 output runs on several tracks at once. On the music side, the studio's virtual singers keep taking on outside game commissions: KAF released BLUE SIGNAL for Azur Lane's 9th anniversary on September 7, and ASU and Wabami sang 1314, an image song for Genshin Impact characters Sandrone and Columbina, revealed during HoYoFair 2026 on the night of September 20. In-house releases continue too, with Harusaruhi's PAUSE on August 21 and Empty old City's collaboration with Dazbee, alongside a second concept EP set for winter 2026 and a 3rd one-man live on February 12, 2027 at EX THEATER ROPPONGI.

The studio's ANMC game project, run with Kazuhide Oka, put Platonica Space on Steam on August 14, 2026 at 1,200 yen, then on Nintendo Switch on August 27 at the same price, with a Steam demo covering Episode 1. The memory-recovery adventure follows five amnesiacs and, per a KAI-YOU roundtable with Oka, KAIRUI, and somunia, treats the inability of people to understand each other as ground shared with Oka's earlier Moonless Moon.

Live work spans domestic venues and overseas markets. Isekai Joucho restaged her 2021 online debut Anima at Zepp Haneda on May 2; KAF played a 29-song Hong Kong set on May 30 with Rime and Isekai Joucho and no streaming. Kuusou, the unit of CIEL and Sooda, released its debut EP CYAN on June 17 and held its first solo virtual mini live, Kuusou Palette, on June 27, free on YouTube with paid multi-angle tickets on Z-aN. Tsumi Juubatsu returned to the event circuit at GOLD DISC on July 11 after a hiatus since last November, and RIM joined RK Music's KMNPARTY vol.8 lineup at Shibuya WOMB on September 13.

The studio also joined the U.S. charity event VTuber Summer Slam 2026, with RIM, KOKO, KAKYOIN, and HINAGESHI streaming Overcooked! 2 in June and raising 1 million yen for Gamers Outreach. The studio and RK Music brought the VSinger UTAMATSURI series to Toyosu PIT on August 22.
