If you have never seen Ouran or need a refresh on what he sounds like here you go :)) https://www.youtube.com/watch?v=wDL3mTxMOJ0 

I'm also going to be a bit picky with this one because he is my absolute favorite character, so sorry in advance :))

Kyoya is calculating and coldly intelligent. Kyoya is an exceptional analyst and manager. His special skill is networking, and he is always aware of how a person could be useful to him later on. While he really does weigh pros and cons rather than go with his feelings, he’s not entirely robotic. He’s difficult to see through, but as co-host Haruhi comments, “You go to all that trouble acting like you're such a big jerk when being a nice guy comes so naturally to you. It seems counterintuitive.”
