what type of girl that Suits – Avocats sur Mesure hibari-san the most?

Opposites attract. But then again, someone who is a good fighter that could rival Hibari in a battle. Someone that can interest him and a bit mysterious and basically independent. Also, some who will understand him and stay with him, no matter what his usual doings are. Also, this person should be able to take care of herself and not have anyone babysitting her. I guess she should be stubborn, not wanting to be saved par someone else other than herself. Last, but not least, someone who can at least make him smile, even if a small one.

What type of girl? :/
Hmmm...
Well, I think he would like an assertive girl who is either mysterious, a good fighter, ou both. She would be the type to compromise with Hibari [but submissive if he gets too close ou makes a move] and have some sort of respect towards Hibari in his way of thinking and fighting. I think that she would also be the type to be able to care for herself and have a tendency to get into trouble, but battles them and wins anyway.
I don't know, that's just my opinion. I can imagine him coming in to save her and she scolds him later, saying that she could take care of herself. :P I think what I'm trying to describe is Tsundere?

the girl must be nice and can make Kyoya -sama smile and specially not annoying

A girl who hates crowds and can be in good relationship with people who don't talk much. Also a girl who is able to make even the most dangerous person SMILE. <3 :D

mistery and cute and kind-desu

Do toi think he'd go for a girl who has wits and guts, normal but not an extraordinary fighter, compassionate and at the same time mysterious.
