About the Series
A Tale of the Secret Saint originates from a light novel series written by Touya and illustrated by chibi. The story follows Fia, who, despite being born into a family of knights, is considered the least talented among them. However, a near-fatal injury triggers memories of her past life as a powerful Saint who once defeated the Demon King. Now possessing the powers of a Saint, Fia is determined to keep her true identity a secret to avoid repeating her untimely demise from her previous life, while still striving to pursue her knighthood path.
The light novel series first began serialization on the Shōsetsuka ni Narō website in January 2019, before being acquired by Earth Star Entertainment for official publication in June 2019. A manga adaptation, illustrated by Mahito Aobe, also began serialization in December 2019.
