@gregger I almost feel like there need to be two different stories, now, with two different genres. This main story would stay nice and fluffy, and we see Ars grow up and continue to demonstrate kindness and get along very well with everybody, while growing in influence and power.
Then we get a second story, focusing mainly on her, dealing with the political intrigue behind the scenes and the ruthless elimination of threats to Ars. It would have some of the other characters, like the butler, playing key roles in helping accomplish those goals. It would handle all of the darker aspects that would ruin the light and fluffy nature of the main story, but would explain how Ars was able to avoid all of the people that would take advantage of his kindness or seek to usurp his authority.
Honestly, if the author could make both work, I'd be super impressed, but I doubt it will actually happen.
