The police officer character in the anime is Togusa, a former detective with the Tokyo Metropolitan Police Department who is recruited into the elite special operations unit known as Public Security Section 9. Before joining the team he served as a civilian police detective, and he is the only member of the unit with no military background, which sets him apart from his mostly former-soldier colleagues. He was brought into Section 9 by its chief, Daisuke Aramaki, who selected him specifically for his fresh perspective, human intuition, and analytical skills, as well as for his excellent detective work, his incorruptible idealism, and his lack of cybernetic enhancement. In a setting where most operatives are heavily augmented cyborgs, Togusa remains almost entirely human, possessing only a cyberbrain for communication and data access.

In terms of personality, Togusa is meticulous, patient, and capable of thinking about and observing problems from angles that others easily overlook. He is the idealist of the group, guided by strong moral beliefs that sometimes get in his way, and he can be emotional and temperamental when confronted with injustice. He is openly suspicious of and reserved about advanced technology, and he values traditional things, which is reflected in his taste for vintage items and his preference for an old-fashioned Mateba revolver over modern standard-issue sidearms. His family is central to his identity, as he is a married man and a father, and his desire to protect ordinary people and uphold justice motivates his work.

His role in the story is that of a lead investigator, and his police instincts often prove crucial to the team's cases. He conducts field investigations, frequently working alongside Batou, and his deductive abilities were instrumental in cracking the Laughing Man case. He also maintains a connection to his past through his friendship with Fukami, a fellow police officer and former associate who was one of the main investigators in that same case. Within the unit, he shares a friendly working bond with Batou, earns the respect of Major Motoko Kusanagi, who values the variety and unpredictability he brings, and remains loyal to Chief Aramaki, who arranged his transfer.

Over the course of the series, Togusa develops from a somewhat insecure newcomer into a more confident and capable operative, though his humanity remains his defining trait. He suffers serious injuries because he lacks the protection of cybernetic replacement, and at times he questions whether he should become more augmented, but he continues to rely on his intelligence and principles. In later events, after the departure of the Major, he rises to become the squad leader of an expanded Section 9, and he eventually undergoes cyberization, the extent of which is not fully detailed.

His notable abilities are grounded in his detective background rather than physical enhancement. He is highly skilled at analyzing evidence, interviewing witnesses, connecting seemingly unrelated clues, and solving complex cases through careful reasoning. He is also trained in firearms and close-quarters combat, and while he cannot match the superhuman strength of his teammates, he remains calm under pressure and can hold his own in dangerous situations. His cyberbrain allows secure communication, data access, and participation in cyber investigations, enabling him to work effectively alongside heavily augmented colleagues. His balanced thinking, patience, and ethical judgment make him the voice of reason within the team, proving that human intuition and integrity remain valuable strengths in a technologically advanced world.
