Cosmic Princess Kaguya!（超かぐや姫！）has dropped its main theme music video just as hype for the Netflix film keeps climbing. The new song “Ex-Otogibanashi,” written by ryo (supercell) and performed by Saori Hayami as virtual diva Yachiyo Runami, turns the classic Kaguya tale into a neon-lit anthem for rewriting your own story. If you want a first taste of the film’s virtual world Tsukuyomi and its music-driven energy before the January 22, 2026 premiere, this MV is your perfect entry point. 🌕🎵
Cosmic Princess Kaguya! Reveals Main Theme MV “Ex-Otogibanashi”
Cosmic Princess Kaguya!（超かぐや姫！）is an original animated film directed by Shingo Yamashita, known for his opening work on Jujutsu Kaisen and Chainsaw Man, and produced by Studio Colorido and Studio Chromato. The story reimagines The Tale of the Bamboo Cutter as a music-driven coming-of-age set between modern Tokyo and the virtual world Tsukuyomi, and will stream worldwide only on Netflix from January 22, 2026.
The freshly released main theme music video spotlights “Ex-Otogibanashi,” with Saori Hayami singing in character as Yachiyo Runami（月見ヤチヨ）—Tsukuyomi’s mysterious manager and top virtual performer. Her clear, gentle vocals sit on top of ryo’s intricate production, instantly selling her as both an AI idol and a guardian of this dreamlike online city.
Virtual World Tsukuyomi and Diva Yachiyo Glow in Neon and Paper Lanterns
Visually, the music video is a tour through Tsukuyomi, a virtual space where anyone can create their own avatar and stage. Traditional Japanese architecture lines the streets, but everything is wrapped in floating neon signage, holographic ornaments and digital stardust. It feels like a festival night that never ends, somewhere between an old-school entertainment district and a cyber city in the sky.
Yachiyo herself appears as a charismatic songstress watching over this world, gliding through the city and performing in front of huge digital moon screens. Cut-ins from the film show Kaguya（かぐや）, Iroha Sakayori（酒寄彩葉）and other characters stepping onto the same stages, hinting that the concert scenes we see here are woven directly into the movie’s emotional peaks.
Ryo of Supercell Turns the Kaguya Legend Into a Rebellious Fairy-Tale Anthem
“Ex-Otogibanashi” opens with a sound like stage lights snapping on, then rushes into a complex, rhythm-heavy backing track and a bright, soaring melody. It balances Yachiyo’s mysterious aura with her love for Tsukuyomi as a place where everyone can create freely. In his comment, ryo describes starting from the idea of a legendary princess born from a “gaming utility pole” instead of bamboo, and wanting Kaguya to finally choose her own ending rather than accept the fate given to her.
The “Ex” in the title points to breaking out of old fairy tales—“go beyond the otogibanashi.” The result is a song that feels both nostalgic and forward-looking, tying classic imagery of the moon princess to the very modern world of VTubers, virtual idols and online fandom.
Music Video Imagery Connects Kaguya, Iroha and the Tsukuyomi Stage
The video mixes original animation cuts with slices from the film, using quick edits to connect everyday life and larger-than-life performances. Scenes of Iroha studying, working part-time and quietly watching Yachiyo’s stream contrast with sweeping shots of Tsukuyomi’s stage, packed with light and motion. As the song swells toward its climax, Kaguya, Iroha and Yachiyo all seem to stand on the same virtual platform, underscoring the film’s focus on bonds built through music and streaming culture.
For fans of music anime, it’s a reassuring sign: the live scenes aren’t just decorative. They are tightly linked to the characters’ choices, friendships and looming farewells, promising a story that uses concerts and streams as turning points rather than simple background flavor.
