The Deputy Chief serves as second-in-command at Machiyama Police Station. His shaved head and beard reflect his past as a riot police officer. Professionally, he is known as a fierce judo practitioner who frequently leads training sessions, specializing in arrest techniques and tactical preparedness. His instruction philosophy prioritizes equipping subordinates with skills to avoid on-duty injuries, showcasing his protective leadership style.

Despite his stern demeanor and tendency to reprimand those who disobey orders, he displays a commitment to his team's professional development, often observing their progress with genuine concern. This creates a dual role as both disciplinarian and mentor. A surprising contrast to his rugged image is his strong affinity for the all-female Takarazuka theatrical revue.

His protective instincts manifest in action: off-duty, he intervened to save officer Kawai from a potentially lethal encounter with a woman concealing a knife, demonstrating vigilance and dedication to colleague safety. Within the organization, he directly addresses operational failures, such as chastising detectives involved in preventable vehicle accidents to reinforce accountability. His leadership consistently blends strictness, underlying compassion, and specialized tactical expertise.
