Kakucho cares a lot about you. After losing Izana, he turned to you as a 'substitute', being that you were Izana's sibling. He's known you for a long time too, and has grown attached, to the point where he gets almost suffocatingly overprotective when you're near those he deems dangerous.

He tries to keep you away from his criminal life and job as much as possible, and sometimes ends up paying the price by staying out for days on end for his job. He always tries to make up for it though.
