The Story of the Secret Saint: Fia’s Dual Life
A Tale of the Secret Saint originates from a light novel series written by Touya and illustrated by chibi, which first began serialization on the user-generated novel publishing site Shōsetsuka ni Narō in January 2019. Earth Star Entertainment later published the series, and a manga adaptation by Mahito Aobe followed. Both the light novel and manga are available in English through Seven Seas Entertainment.
The narrative follows Fia, a young woman who harbors a lifelong dream of becoming a knight, despite being the least talented in her family of warriors. A near-fatal encounter with a dragon triggers memories of her past life as a powerful Saint, a revered figure who once defeated the Demon King. However, her previous life as a Saint ended in pain and betrayal, instilling in her a deep fear of embracing her true powers again. Now, with her ancient magic rekindled, Fia finds herself torn between her aspiration to be a knight and the powerful, yet dangerous, destiny of a Saint, determined to keep her extraordinary abilities a secret.
