The vice president of the Host club and the Cool type. He is often called "Mother" by Tamaki and "Shadow King" by the rest of the club. He is behind most of the Host Club schemes and the other club members tend to go along with whatever Kyoya says, sometimes even favoring his leadership over Tamaki's. Despite their opposite personalities, Kyoya and Tamaki have been best friends since their last year of middle school, when Tamaki transferred to Ouran. He is a third son and has spent his whole life honoring his family name and yielding his true abilities so as to not overshadow his brothers; however, it is clear that Kyoya has more ambition, drive, and talent than both of them. Throughout the series Kyoya refers to the fact that as he is a third son he won't inherit his father business, although he has slowly started to come out of that mindset after his becoming friends with Tamaki. He believes life is a game and will lose out if he doesn't have 'fun'. He also manages most of the finances with the club and has a habit of not revealing important information to the other hosts until the problem at hand is already over.
