Astrea is the strongest sword master in the world. One day, she awakens to the fact that she has been reincarnated as a character in a novel. And not just any character, but the one who is destined to be killed by the final boss, the God of Evil... Then, while hiking in the mountains, she saves a child from a group of thugs, only to learn that this very child is fated to one day become the God of Evil. ‘Since it has come to this, maybe I should just raise him well and completely reform him?’ So she ended up bringing him home to raise him, but... “Rea. Where are you going? Are you going to see that guy again?” He has become an obsessive young man who follows me around everywhere, watching my every single move. Somehow.... I think I raised him the wrong way.
