Otaki Aoyama

Serving as the primary directors of the Motor Club alongside Toraichi Tamiya, this individual frequently burdens Keiichi with an overwhelming workload. Despite their demanding leadership style, they hold deep admiration for Keiichi’s exceptional talents behind the wheel and under the hood. Both shared a profound romantic interest in the club's former director, Chihiro Fujimi, though she ultimately prioritized the organization over them. Eventually, the responsibility of directing the club is handed over to Keiichi.
