The upcoming fantasy series A Tale of the Secret Saint has revealed its theme music lineup ahead of its April 2026 debut. Rising artist Kaya will perform the opening theme Flare of Soul, while the Utahime Dream Allstars ensemble delivers the ending track Stellar.

Kaya described the song as an anthem of courage and sincerity that mirrors heroine Fia Ruud’s determination to follow her own path despite fate’s weight. In contrast, the ending theme embraces warmth and unity, expressing the bonds that power the show’s mystical world.

Produced by Felix Film, the anime adapts the light novel by Touya and chibi, blending knightly ambition with saintly magic. Director Tomoe Makino, writer Deko Akao, and composer Kenichiro Suehiro promise a balance of emotional fantasy and grand adventure.
Fans can expect stunning visuals and heartfelt storytelling when the series debuts this spring—an uplifting new entry for fantasy lovers.
