About A Tale of the Secret Saint:
A girl named Fia dreams of becoming a knight even though she has been told she has no talent for the sword.
Just as she is on the brink of death, she suddenly recalls her past life as a Great Saint, possessing an extraordinary cheat-like ability!
In that past life 300 years ago, she fought alongside knights only to be brutally slain by the Demon King’s right-hand man.
With the return of her memories, Fia also regains the power of the Great Saint.
However, she remembers the threat from the Demon King’s right-hand man:
“If you are reborn as a saint, I will kill you.”
Determined to live as a knight while keeping her power hidden, Fia sets out on her new path.
Yet, unable to turn a blind eye to the wounded, she frequently uses her powers in the incidents she encounters.
Will she be able to keep her saintly identity a secret!?
