Next January’s Cosmic Princess Kaguya! anime film, which features music from multiple Vocaloid composers and has a cover of “World is Mine” in its current trailers, is continuing to integrate Vocaloid love in its marketing via a Saori Hayami (as her character Yachiyo) cover of 2019’s “Lonely Universe.”
The song’s creator, Aqu3ra, is among those aforementioned composers who are involved in the anime. The original “Lonely Universe” featured vocals from flower and Hatsune Miku.
For Hayami’s cover, Matcha was employed to provide the video’s illustrations, while _Sayuri and SHIG have logo and movie credits, respectively.
Cosmic Princess Kaguya! (Cho Kaguya-hime!) will premiere on Netflix on January 22, 2026. The movie will deliver a modern/futuristic, music-infused spin on the Princess Kaguya tale as directed by Shingo Yamashita (Pokétoon chief director, opening storyboard artist and director for Chainsaw Man, Jujutsu Kaisen Season 1, and more). Here’s the premise:
Tsukuyomi is a virtual realm where hopes and dreams come together. Iroha Sakayori, a 17-year-old high school student in Tokyo, leads an extremely busy life trying to balance part-time work and academics. She finds peace by watching a popular streamer named Yachiyo Runami, who is the administrator of an online virtual space called Tsukuyomi. Iroha frequents Tsukuyomi, where people can live different lives and freely pursue their creativity, and she passes the time by supporting Yachiyo and playing battle game to earn a little extra money.
On her way home one day, Iroha finds a telephone pole shining with iridescent hues. To her surprise, an adorable baby emerges from the pole. Unable to abandon it, Iroha takes the infant home and watches her rapidly grow into a girl her own age.
“Are you Princess Kaguya?” The grown-up Kaguya develops a self-indulgent personality. At Kaguya’s fervent request, Iroha helps her start streaming in Tsukuyomi. With Iroha as producer and songwriter and Kaguya as streamer and singer, the two grow steadily closer. Little do they know that ominous forces lie in wait, eager to take Kaguya back to the moon.
This is the tale of Princess Kaguya as never seen before.
Aqu3ra aside, the Vocaloid producers involved with the anime are ryo (supercell), 40mP, HoneyWorks, yuigot/Aqu3ra, and kz(livetune).
