A Tale of the Secret Saint Vol. 2 (manga)

Fia Ruud, youngest of the Ruud family of knights, was easily the least talented swordsperson of her generation–at least, until her past powers as a great saint returned! However, her newly gained aptitude at both magic and swordplay were not without their price. In order to prevent the tragedy of her last life from reoccurring, Fia must keep her identity as a saint under wraps! Unfortunately for her, a learning expedition with the Fourth Monster Tamer Brigade goes awry, and her power’s at risk for all to see!
