Yoshio Ootori

Yoshio is portrayed as a cold and calculating father. Kyoya tries hard to please him, despite the fact that his father has set impossible standards for him to meet. Yoshio displays little understanding or compassion towards his children and has already planned out the lives of his sons as his successors. In the manga, he acknowledges Kyoya as a possible successor despite being the third son. In the anime, he states he has already decided that Kyoya will inherit Ootori Medical from him, only to have the Tonnerre Group attempt a hostile takeover that is thwarted by an anonymous investor. Said investor turns out to be Kyoya himself, who purchases the company and returns it to his father, anonymously.
