Deko Akao (Komi Can’t Communicate, Flying Witch) is overseeing the series scripts, while Satomi Kurita (Dahlia in Bloom) is responsible for character designs.

What is A Tale of the Secret Saint About?
The series follows Fia, a young woman born into a lineage of knights who dreams of becoming one herself, despite lacking natural talent in swordsmanship. A near-death experience, however, triggers memories of her past life as a powerful Saint from a bygone era—a woman who once defeated the Demon King with potent healing and protection magic.
Fia remembers the tragic end of her past life and a ominous threat that if she were reborn as a Saint, she would be found and killed. Determined to avoid a similar fate, she vows to keep her powerful abilities a secret and continue her path as a knight. However, her inherent compassion often leads her to use her Saintly powers in moments of crisis, making it increasingly difficult to conceal her true identity. The story blends action, fantasy, and comedy as Fia navigates her desire to be a knight and the destiny that constantly pulls her back toward being a Saint.
