Togusa, a former police detective recruited into Public Security Section 9, leverages his analytical skills, human intuition, and minimal cyberization—initially limited to a cyberbrain implant—setting him apart from his heavily augmented colleagues. His perspective and motivations are frequently shaped by his role as a family man with a wife and children.

In earlier continuities like *Stand Alone Complex* and *Solid State Society*, Togusa's police instincts prove vital, cracking high-profile cases including the Laughing Man investigation. His archaic Mateba revolver symbolizes a preference for analog reliability. Following Major Kusanagi's departure in *Solid State Society*, he ascends to field operations leader. This demanding role strains his family life and prompts discussions about full cyberization to enhance his capabilities. During this period, his cyberbrain is hacked, leading to a suicide attempt to protect his daughter, averted by Kusanagi's intervention.

In *SAC_2045*, after Section 9's disbandment, Togusa works with the Japanese police while other members operate abroad as mercenaries. Chief Aramaki recruits him to reform Section 9 and locate former members. Reunited with the team, he confronts emerging "Post-Human" threats possessing superior cyberbrain abilities. His connection to the Post-Human antagonist Takashi Shimamura becomes pivotal when exposure to a virus carrying Shimamura's memories triggers hallucinations and a psychological breakdown. This culminates in Togusa vanishing during a critical encounter, witnessed only by Tachikomas while appearing invisible to Batou, highlighting his vulnerability to advanced cyberbrain manipulation. Though later found unharmed, this storyline remains unresolved within the season.

Togusa's character arc consistently explores tensions between his human identity and the cyberized world, his dedication to justice, and the personal sacrifices required by his role in Section 9.
