Shadow Warriors goal is still suspicious. If they wanted to get rid of magic, why so? If it's only their leader's goal the other members don't have reason to do so. Much less to a shallow goal like that. The old dwarf guy for example, he seems a good guy cuz he was buddies with the Hero party before.

Serena keep refusing Dietrich cuz in the novel their child would become a tyrant and it was HER who pushed her kid to be like that. What bothers me is, if she knows the story/future shouldn't she just change how she will raise her kid instead? The solution she came up is to marry the 1st prince so her future kid wouldn't be born.

Usually, in stories like this—where there's a runaway mom with her child and a CEO dad—the mom is the main character. But it's refreshing to see that the main character is the child instead. She's a reincarnator too, which explains her abilities compared to other children, who typically have unnatural skills for their age.
Serie may be too overpowered in the current era, or even irrelevant in a world of peace, but being killed by an assassination from magic haters feels a bit dull. If she's gonna die anyways at least make her death reasonable.
