Gomesu Tonda is the Commissioner of Police at the Katsushika Police Headquarters, holding a superior rank to Chief Patrol Officer Daijiro Ohara of the Kameari Park police box. Tonda maintains a generally mild, caring, and understanding demeanor, typically issuing orders with calm seriousness. He interacts effectively with subordinates throughout the force but exhibits significant anger when their actions cause major damage or tarnish the police reputation. Physically, Tonda is slightly chubby and of average height. He has dark brown curly hair and a matching mustache, with thick, curved eyebrows separated above the nose. His standard uniform consists of a blue coat, white undershirt, black tie, blue pants, and black shoes. A frequent habit is standing with hands clasped behind his back during conversations or in his office, reinforcing his professional composure. His voice is notably deep and distinctive among Katsushika officers. On his days off, Tonda babysits his three children and six grandchildren. During work hours, he occasionally engages in carefree or inappropriate activities like reading men's magazines in his office, sometimes causing embarrassment when interrupted by colleagues. Sources suggest his birthdate is either June 11 or July 7, the latter coinciding with the Tanabata festival and shared with Reiko Akimoto. Tonda demonstrates a trusting relationship with Kankichi Ryotsu, often assigning him tasks directly. When Ryotsu behaves inappropriately, Tonda typically consults Ohara for explanations and collaborates with him to reprimand Ryotsu, especially in cases involving major destruction. He addresses Ohara casually and warmly as "Ohara-kun," indicating their friendly dynamic. Together, they strategize methods to manage Ryotsu's erratic behavior and protect their professional reputations.
