Idk how to put a spoiler warning
It literally states that anyone of Parvis blood is extremely difficult to control… and because Ragibach is in Cosette’s fragile body, they can’t exert too much power, either. The knight stuff could be brushed off because maybe she’s just doing her duties off screen. It’s not important in the later chapters. You could even consider her fight with Ragibach as knightly duties
(I can’t find the spoiler checkbox cuz I’m messaging on phone but this is a spoiler)
Obviously the guard isn’t of Parvis blood. Not even the uncle is of Parvis blood bro Ragibach could control him too if they wanted and you can infer that Ragibach made sure that the father and themself weren’t near Beatrix + they used a lot of energy and power to do it i’m half convinced you just weren’t reading the manhwa atp

Am I the only one who thinks that she was such a capable character in the start. She was a captain. Undefeated by her knights but like she forgot the plot. There is no mention of her being her being a knight in later chapters.
Author lost the plot frfr. And if the demon is able to use thing manipulation... y tf is not able to manipulation the aunt to give it to her. Its that simple.
Idk bro makes no sense
