Toraichi Tamiya and Otaki Aoyama are the directors of the Motor Club. They make life very hard for Keiichi by passing on a lot of work to him. However, they have a great deal of respect for Keiichi's abilities both as a mechanic and a driver. In the manga, they pass the directorship of the Motor Club to Keiichi. They were also both in love with the original director of the motor club, Chihiro Fujimi. However, she rejected both of them for the sake of the club.
