Nagi Yanagi Closes a Loop She Started in 2010
Yanagi's connection to Witch on the Holy Night predates the movie by well over a decade. supercell released "Hoshi ga Matataku Konna Yoru ni" in 2010 with her on vocals, and in 2012 the track was picked up as the ending theme for Type-Moon's PC release of the visual novel. Singing the film's theme puts her back on the same property 16 years after that single.
The gap on the supercell side is nearly as long. Her last vocal credit with the project was the second album Today Is A Beautiful Day, released in March 2011.
ryo credited the film with waking the project up. "If this offer hadn't come along, I think supercell would still be asleep," he said in a comment published with the announcement, adding that he was genuinely glad to be continuing supercell with Yanagi's voice. Yanagi's own comment to Music Natalie, the Japanese music news site that ran the story, was shorter and more startled. She said she was surprised and happy to be singing a new supercell song "in this day and age," and that she remembers the day she recorded "Hoshi ga Matataku Konna Yoru ni" like it was yesterday.
What supercell Has Been Doing Since
ryo built supercell as a collective pairing him as composer with several illustrators and designers. Its Hatsune Miku originals cleared 20 million combined plays on Niconico, Japan's long-running video platform, and the group made its major-label debut in March 2009. The self-titled first album sold more than 100,000 copies and took The Best 5 New Artists prize at the 24th Japan Gold Disc Awards. The first single, "Kimi no Shiranai Monogatari," had Yanagi guesting under the name nagi, served as the Bakemonogatari ending theme, and became a major hit of its own.
After Today Is A Beautiful Day reached number three on Japan's Oricon weekly chart in 2011, supercell ran an open audition for a new vocalist and chose Koeda, from Fukuoka, out of more than 2,000 applicants. Two singles followed: "Giniro Hikousen" in December 2012, the opening theme for the anime film Nerawareta Gakuen, and "The Bravery" in March 2013, which included the ending theme for the TV anime Magi. Then the project went quiet.
Yanagi kept working through all of it. The Kansai-born singer-songwriter started out in live venues and online in 2006 and made her major-label debut in February 2012 with the ending theme for Waiting in the Summer. She released the 20th-anniversary album ENcore in June 2025, then put out "Natsu no Sumika" as the episode 9 ending theme for the TV anime Turkey!.
The Film Around the Song
Witch on the Holy Night is produced at ufotable (Demon Slayer, Fate/stay night: Unlimited Blade Works), the studio that has handled most of Type-Moon's screen adaptations. Masashi Takeuchi directs, with Moe Tsuzuki on character design and Hideyuki Fukazawa scoring. Haruka Tomatsu voices Aoko Aozaki, Kana Hanazawa plays Alice Kuonji, and Yūsuke Kobayashi plays Soujyuro Sizuki. The film adapts the 2012 visual novel written by Kinoko Nasu.
The 90-second final trailer went up on Aniplex's YouTube channel on September 30, 2026, and it plays the first public excerpt of "Yoru to Ao" over footage from the film. That's the only way to hear any of the song right now.
Looking Ahead
Witch on the Holy Night opens in Japan on November 20, 2026. Crunchyroll and Sony Pictures Entertainment hold the international theatrical rights, and US and Canadian screenings start January 29, 2027 in both subtitled and English-dubbed versions. The UK, Ireland and India share that date, Saudi Arabia and the UAE get it on January 21, and several European markets land between January 26 and 28. No streaming window has been announced anywhere.
No format or release date has been set for "Yoru to Ao" itself. Music Natalie says details will follow, so there is no word yet on whether the song arrives before the Japanese premiere or with it. The source material is already available in English: Aniplex has published the visual novel on PlayStation 4 and Nintendo Switch since December 2022, and Anime News Network reported it has passed 150,000 copies worldwide.
