The rival idols are crashing the party. Twin Engine announced on November 13 that Black onyX, the pro gamer and idol trio from the hit anime film Cosmic Princess Kaguya! (Cho Kaguya-hime!), will guest at the movie’s free online concert, Tsukuyomi Kansha-sai: Mecha-Uma Pancake Party, on December 26.
Black onyX takes the stage
The news dropped in a surprise special hosted by Kaguya on the film’s official YouTube channel, along with an announcement video and a new alternate event visual. The video is set to Black onyX’s song “OnyXXX” and features all three members:
- Akira Mikado (voiced by Miyu Irino)
- Rai Komazawa (voiced by Yuma Uchida)
- Noi Komazawa (voiced by Yoshitsugu Matsuoka)
The special also included voice messages from the trio, and Twin Engine hints that Akira is planning a surprise for someone. In the film, Black onyX is a top group in the virtual world Tsukuyomi who battle Kaguya and friends in the game KASSEN, but they never got a live performance on screen, so this will be a first for fans.
Event details
- Date: Saturday, December 26, 2026 at 9:00 p.m. JST (4:00 a.m. PT the same day)
- Where: The official YouTube channel and VRChat, simultaneously
- Cost: Free
- Main performers: Kaguya, Iroha Sakayori and Yachiyo Tsukimi, in their Amaterasu stage outfits
The VRChat side recreates Tsukuyomi as the “VR Tsukuyomi World,” with a tutorial area guided by Yachiyo (already open), a gallery for fan art and fan-made worlds, and a central torii gate area where characters drop by.
A breakout original
Directed by Shingo Yamashita, known for his opening sequences for JUJUTSU KAISEN and Chainsaw Man, Cosmic Princess Kaguya! is a Studio Colorido and Studio Chromato production with songs from Vocaloid producers including ryo (supercell), kz (livetune), 40mP and HoneyWorks. It premiered worldwide on Netflix on January 22, 2026, then opened in Japanese theaters on February 20. Its planned one-week run kept getting extended, and Twin Engine says it drew 1.34 million moviegoers and earned 2.7 billion yen, a rare result for an original anime film. The film follows Iroha, a busy high schooler who finds a baby inside a glowing utility pole, watches her grow into Kaguya, and helps her become a streamer in Tsukuyomi.
