Bookworm/Honzuki
Even the first villain which is rather stupid, did things that would normally work, but because the MC's unusual logic and her allies' actions, they're foiled.
Spoiler below cuz too lazy to stack spoiler in spoiler (the spoiler goes up to the end of arc 2)
First he tried smaller harassment - demanding more money from her workshop, giving her troublesome attendants
Her merchant partner convinced the man in charge that there's only so much they can offer, alluding to the temple's own suffering at lack of fund on what'll happen if they try to squeeze her too much.
The troublesome attendants ends up getting befriended, one turning from the most troublesome kid in the temple into a loyal, if a little rude, attendant.
Next he tries to spread bad rumors about her among the nobles, leading to even one guy attempting to harm her during a major event.
The reputation among nobles is nothing concerning the main girl, given that nobles rarely visit the temple and the main girl live away from the noble section anyway.
The guy who tried to hurt her got himself executed for recklessly making the situation worse - they were trying to take down this giant plant monster, and when he injured the girl her blood cause more of those plant to spawn, not to mention the girl was there to heal the land after the plant monster is taken down, otherwise the land become infertile and monster will move to more fertile land i.e. villages nearby, so if she's unable to heal the land due to the injury, it'd be his fault.
(the rest of the knights get to witness first hand why she's so highly valued when she healed the land rather quickly, and alone at that)
Then even in his final gambit of calling over a foreign noble to just abduct her.
The girl resisted because she gives no fuck if you're noble or what, hurt her family and she snaps.
And long before this plot even happened, another person has given her a 'in case of emergency, use this' item.
Well, the item was actually 'I accept being adopt by you' button, so when the girl did that, she is technically a noble now, and of higher rank than the two attacking her too, making their excuse of 'less majeste' invalid and if anything reverse that on them.
