Synopsis
Fia, daughter of a knight, was trying to become a knight when she almost died and remembered her previous life as a great saint — the most powerful kind, nearly extinct. Her immediate concern: in her previous life, the Demon Lord's right hand threatened to kill her if she ever reincarnated as a saint. So she's going to become a knight, live quietly, and absolutely not use the ancient lost magic. She almost convinced herself. The problem is the power is too useful and she keeps using it anyway.
