The upcoming TV anime A Tale of the Secret Saint（転生した大聖女は、聖女であることをひた隠す）has revealed the artists and titles for its opening and ending themes. If you’re curious what kind of sound will follow Fiia’s secret life as a knight and hidden great saint, here’s a quick look at the music that will frame each episode.
Kaya Brings ‘Flare of Soul’ to A Tale of the Secret Saint
The opening theme, “Flare of Soul,” is performed by vocalist Kaya, known in Japan for her powerful live presence and award-winning TV singing contest history. Written, composed, and arranged by Hiroaki Suzuki (SUPA LOVE), the song reflects Fiia’s choice to walk her own path, even when it means resisting the role the world expects from a “saint.” Kaya describes it as a track about moving forward through pain and doubt, guided not by logic but by the heart. You can learn more about her work on her official site: visit Kaya’s official page.
Utahime Dream All Stars Close Each Episode with ‘STELLAR’
The ending theme, “STELLAR,” is performed by Utahime Dream All Stars, a special unit from the media-mix music project Utahime Dream. Eight “Utahime” characters and their voice actors join forces to deliver a song about believing in the light, letting go of excuses, and stepping toward the future. Cast members such as Rena Yamazaki, Anna Suzuki, Arisa Sonohara, Kaya (as HiREN), Karin Isobe, Tomomi Jiena Sumi, Reo Kurachi, and Yume Takeuchi all contribute vocals, giving the track a rich, ensemble feel. The unit and project share more music and covers on their hub: check the Utahime Dream site.
Songs, Cast, and Web Radio Building Hype for 2026
To go with the new themes, the staff also unveiled fresh character visuals for Fiia, Xavilia, Savis, and Cyril, illustrated by character designer Satomi Kurita. Each piece highlights the group’s different strengths, from Fiia’s quiet resolve to Xavilia’s sharp gaze. A promotional web radio has also been announced, hosted by Shion Wakayama (Fiia) and Shinnosuke Tokudome (Xavilia), with more details and guest info to be revealed later. With theme songs locked in, visuals updated, and a 2026 April TV broadcast ahead, the series is steadily turning music announcements into real momentum.
