[Character Desc]
Kyoya's keen business acumen lends itself to handling all the financial and planning aspects of the Host Club, from managing budgets to selling off merchandise in order to keep the club solvent, while still funding Tamaki's extravagant schemes. His manner in dealing with clients is self-assured and charming, and he is said to be the "Cool" type. He uses his wiles as a Host to entertain guests while simultaneously earning the club money through events, online auctions of personal Host objects, fanzines and doujinshi. As a complete foil to Tamaki, even in appearance, he often realizes things Tamaki or the others are too naive to understand, keeping the information to himself for his own amusement or to watch things play out in order to determine how best to help the other members. He is the "Mommy" to Tamaki's "Daddy" position in the club, though he eschews the title in relation to Haruhi Fujioka in the anime; while in the manga, he sometimes uses the title to his advantage.
