Francesca's dad's so protective of her. He's also taken the opportunity to make dresses for her so that she doesn't need to worry if she ever needed a pretty dress.
It's actually pretty cute to see a mob boss dad who's extremely protective of his daughter. He'll intimidate you in public, but in private, he'll be a doting dad! The contrast is adorable. I'm sure he knows how to fight too, so he's kinda like Kiryu! I just wish he didn't feel the need to "fix" anything wrong with her life.
Leonardo's very calculating. I'm sure he anticipated that her dad was this protective, so he signed a blood oath to make sure the date goes through. He's already promised to fix the drug problem, so seeing him do this seems to be a sign that he's utterly devoted to Francesca.
Graziano's a straight brawler compared to Leonardo, and he probably doesn't have much influence in the underworld. Thanks to Leonardo's restraining ability, he probably would lose in a fight against him. But seeing him threaten Leonardo like that shows he really loves Francesca as a sister!
