A Tale Of The Secret Saint Synopsis: The story follows Fia, a young woman who has always dreamed of becoming a knight, despite being the weakest in her family of warriors. She trains relentlessly to prove herself, but when she finally gets a chance to prove her worth by slaying a small demon, she ends up facing a dragon instead.
As she suffers a fatal injury, memories from a past life flood her mind—revealing that she was once a legendary Saint who defeated the Demon King. However, her former life ended in suffering because of her immense power, making her fearful of embracing that part of herself again. Now, with her long-dormant magic rekindled, Fia must navigate her new reality, torn between her dream of being a knight and the overwhelming power of her past self.
The series originally debuted on Shōsetsuka ni Narō (Let’s Be Novelists!) in January 2019, before being picked up by Earth Star Entertainment, which published the first print volume in June 2019. The 11th novel volume is set to release in a few days on March 14th, 2025. The series has gained significant recognition, ranking second place in the Tankōbon and Novel rankings in the 2025 and 2024 editions of Kono Light Novel ga Sugoi! (This Light Novel Is Amazing!)—one of Japan’s most prestigious light novel rankings. The manga adaptation by Mahito Aobe began serialization in Comic Earth Star in November 2019, with the 12th volume releasing on March 12, 2025.
For fans looking to dive deeper into the world, Seven Seas is also publishing the prequel series, A Tale of the Secret Saint ZERO.
