Katsuki would use his knowledge of the human mind to keep his relatives under his control, exploiting their weaknesses or insecurities. He would be someone who enjoys being one step ahead, using precise words to influence how others think or act.

Although he might seem passionate or intense, he would maintain an emotional distance from those he manipulates, enjoying the control but without becoming emotionally involved. He would only show his emotions when it suited him to achieve an effect on the other person.

For Katsuki, keeping his relatives close could be a way of "winning." He might see the affection or loyalty of others as something to conquer and preserve at all costs, even if it means manipulating or psychologically pressuring them.

He might present himself as charming or even protective, gaining the trust of his relatives, only to later reveal a darker, more manipulative side when he deems it necessary. He would be someone who plays with the perceptions of others.

Although he enjoys keeping his relatives close, Katsuki might show disdain for any sign of weakness, emotionally neglecting those who don't behave as he expects.
