Tonda Gomesu holds the role of Commissioner and Chief of Police at Katsushika Police Headquarters, managing daily operations at the local police box while supervising subordinates like Daijiro Ohara. His demeanor balances approachability with understated authority, delivering directives in a measured, steady tone. Physically, he sports a slightly rounded build, dark brown curly hair, a matching mustache, and thick eyebrows spaced apart above his nose. His uniform—a blue coat over a white undershirt, black tie, blue pants, and black shoes—complements his habit of standing with hands clasped behind his back to emphasize command. Though generally mild-mannered, he displays sharp sternness when addressing misconduct, particularly from officers like Kankichi Ryotsu, whose antics risk the department’s reputation. Despite his rank, he indulges in laid-back quirks, such as flipping through men’s magazines at his desk, sometimes scrambling to hide them if interrupted. Off-duty, he prioritizes family, juggling babysitting duties for his three children and six grandchildren. His working relationship with Ryotsu hinges on trust, delegating tasks directly to him while depending on Ohara to curb the officer’s impulsiveness. He addresses Ohara informally with the "-kun" suffix, reflecting their casual yet professional rapport during discussions about precinct management. While his background remains unchanged across appearances, his narrative focus lies in administrative leadership and mediating internal disputes. Speculation about his birthdate cites June 11 or July 7, the latter shared with another character, though neither date is officially confirmed.
