The true manager of the club, Kyoya is shown to be calculating, knowledgable, and scheming, although not a bad person (to an extent).

He is from a very powerful big-business family that deals predominantly in medicine, and secretly feels slightly overshadowed by his older brothers, who he knows are far more likely to one day inherit the company instead of him. However, despite the circumstances, he does have great confidence in his own abilities and finds the situation to be more of an interesting game than a roadblock.

He does all the financial and planning aspects of the Host Club, from managing budgets to selling off merchandise.

His manner towards clients is very pleasant and civil, and is said to be "the cool type." As a complete foil to Tamaki, even in appearance, he often realizes things Tamaki or the others are too naive to understand (and usually keeps the information to himself for his own amusement), and is the "Mom" to the father figure of Tamaki. He is often polite to people who are in power or related to it, and claims he only helps people so he can get ahead in the business circles. Haruhi finds this untrue when he keeps a woman from being scammed before realizing she was the wife of a important man.
