Kazuya Shibuya serves as president at SPR. Despite being highly intelligent and sharp-witted, he's often referred to as "Naru" due to his narcissistic tendencies. Unlike other characters in the series, he doesn't possess any spiritual abilities and relies on his companions' skills and his own intellect for problem-solving. Although he may come across as cold and critical to others, Kazuya genuinely cares about his friends and has earned their trust and respect. He shares a close bond with Mai, addressing her by name unlike Masako, who becomes envious of Mai because of it.
