Synopsis:
Feer, who was aiming for a knight as a knight's daughter, recalls the previous life, which was a "great saint" when he died. Well, this is a "lost magic" that has now become a fairy tale!?
Moreover, the strongest monster, the black dragon, became my devil!? But in the previous life, I was threatened by the right arm of the Demon King to "kill if she is reborn as a saint".
If you use such a power, you may be killed by a saint in one shot. … That's why I hide my identity and become a knight with Toru Hatsushi!
