Ugh I have finally found a rare gem in the mix! I always like confident princesses or confident noble daughters, but they never seem to be VIOLENT ENOUGH!! Like omg, let out your anger PHYSICALLY!!
This is like the fever dream I have been dying for. A Duke's Daughter with manners, intelligence, and STRENGTH TO BEAT LOUSY PEOPLE TO THE FLOOR!!
If you want this but less violent I would suggest checking out Koushaku Reijou no Tashinami!! She is a duke's daughter with CLASS AND INTELLIGENCE. But she doesn't exactly take down her opponents with a punch or two.
