Eve, who reached listeners worldwide with "Kaikai Kitan" from Jujutsu Kaisen, and suis, the vocalist of Yorushika, a band with devoted followings inside and outside Japan for its literary lyrics and clear voice. Two of the most recognizable figures in Japanese music are teaming up for the third time, this time to open a fantasy anime that already carries the comics industry's equivalent of an Oscar.

[Update, July 31, 2026] The anime premiered on schedule on April 6, 2026 and ran for 13 episodes, ending on June 29. A second season was announced immediately after the finale aired. The manga had reached 16 volumes as of May 2026, and Crunchyroll handled streaming outside Japan.

Eve and Yorushika's suis Reunite for 'Witch Hat Atelier' Anime Opening Theme

Japanese singer-songwriter Eve has written a brand-new song, "Kaze no Anthem feat. suis from Yorushika" ("Anthem of the Wind"), which will serve as the opening theme for the upcoming TV anime Witch Hat Atelier, premiering on April 6, 2026. The track features suis, the vocalist of beloved Japanese band Yorushika, as a guest singer, marking the third time these two artists have collaborated.

A promotional video featuring a preview of the song has already been released, giving fans their first taste of the pairing set against the anime's visuals.

Who Is Eve? Japan's Anime Theme Song Powerhouse

Eve started out as an "utaite," a Japanese term for singers who share cover songs on the video platform Niconico, before establishing himself as one of Japan's most in-demand singer-songwriters for anime themes.

His breakthrough came in 2020 with "Kaikai Kitan," the first opening theme for the massively popular anime Jujutsu Kaisen. The song became a global phenomenon: its music video has surpassed 420 million views on YouTube, it accumulated over 440 million streams on the Billboard Japan charts (as of August 2025), and Spotify crowned it the most-streamed song by a Japanese artist overseas in 2021.

Since then, Eve has kept working steadily in anime, with "Fight Song" for Chainsaw Man, "Bokurano" for My Hero Academia Season 6, "Iolite" for Pokémon, and "Teenage Blue" for Blue Box. In 2024, his first Asia tour, "Culture," sold out every show across seven cities.

Yorushika and suis: The Voice That Captivates the World

Yorushika is a Japanese music project formed by composer n-buna and vocalist suis. Known for literary-inspired lyrics and delicate soundscapes, the duo has cultivated a passionate fanbase both in Japan and internationally. suis's crystalline, emotionally resonant voice has made Yorushika one of the most-streamed Japanese acts on platforms like Spotify and YouTube, with a notably high percentage of listeners coming from outside Japan.

The chemistry between Eve and suis has been celebrated by fans since their first collaboration, "Heikousen" (Parallel Lines), released in February 2021 as the theme song for a Lotte Ghana Chocolate campaign. Their second team-up came later that year on "Uchuu no Kisetsu" (Season of the Universe), a track by Vocaloid producer Lanndo featuring both artists. Fans have long described the blend of Eve's warm, textured vocals with suis's ethereal clarity as magical, which makes a third collaboration on a fantasy anime about the beauty of magic feel apt.

The Source Material: An Award-Winning Fantasy Manga Loved Worldwide

Witch Hat Atelier (Japanese title: Tongari Bōshi no Atelier) is a fantasy manga written and illustrated by Kamome Shirahama. Serialized in Kodansha's Monthly Morning Two magazine since 2016, the series has surpassed 7.5 million copies in circulation worldwide across 16 volumes published in Japan as of May 2026.

The story is set in a world where magic is woven into everyday life, but only those born as witches can cast spells, or so everyone believes. Coco, a young girl who dreams of becoming a witch despite lacking magical abilities, one day witnesses the traveling mage Qifrey drawing magical runes and realizes the truth: anyone can use magic if they know how to draw the right symbols. This forbidden knowledge thrusts Coco into a hidden world of sorcery, secrets, and danger.

What makes Witch Hat Atelier stand out internationally is Shirahama's artwork. Drawing inspiration from Renaissance paintings, Art Nouveau, American comics, and French bande dessinée (graphic novel tradition), her illustrations have been praised as "breathtaking" and "sumptuous" by Western critics. Shirahama is already well-known to Western comics fans for her variant cover art for Marvel and DC titles including Star Wars: Doctor Aphra, Deadpool, and Batgirl.

The manga's accolades speak for themselves:

  • 2020 Eisner Award – Best U.S. Edition of International Material, Asia (often called "the Oscars of Comics")
  • 2025 Harvey Award – Best Manga
  • 2019 Japan Expo Award (France) – Daruma d'or manga
  • 2018, 2022, 2023 Manga Barcelona Award (Spain) – Best Seinen

The series has been compared to Studio Ghibli's Spirited Away for its sense of wonder, a touchstone often cited by Western fantasy fans.

The Anime: A Top-Tier Production Team

The anime adaptation is being produced by BUG FILMS, the studio behind Summer Time Rendering and Zom 100: Bucket List of the Dead. Director Ayumu Watanabe, celebrated for his work on the visually stunning film Children of the Sea, leads the project. Series composition and screenplay are handled by Hiroshi Seko, who previously wrote for Attack on Titan and Jujutsu Kaisen. Character designs are by Kairi Unabara and the score is by Yuka Kitamura.

The ending theme, "Tada Utsukushii Noroi" (A Beautiful Curse), is performed by Nakamura Hak.

The voice cast includes Reina Motomura as Coco, Natsuki Hanae (known for Demon Slayer's Tanjiro) as Qifrey, Hibiku Yamamura as Agott, and Yuichi Nakamura as Olruggio. The anime will broadcast on TOKYO MX and BS11 starting at 11:00 PM JST on April 6, with streaming available on Netflix and ABEMA. A special advance screening of episodes 1–3 is scheduled for March 15 at Shinjuku Piccadilly in Tokyo.

Comments from Eve and suis

Both artists shared comments alongside the announcement's promotional video. Eve described magic not as a special power but as something that lives in the hands of anyone who keeps drawing their wishes, explaining that he built the song around the theme of "resonance" with suis. suis, for her part, said Eve's song overflows with the beauty of a gently woven magic, and that from the first listen she wanted to hear it open Witch Hat Atelier.

Why This Landed So Hard Overseas

The reaction abroad comes from how the pieces overlap. Eve is a familiar name to international anime fans through "Kaikai Kitan." Yorushika draws an unusually high share of its streams from outside Japan. And the source manga, available in English, French, Spanish, Korean and more, already had a readership built partly on its Eisner win. Three separate audiences rarely converge on one project. The manga has also been recommended in US outlets as a natural fit for anyone who loves Spirited Away, which is a large constituency.
