Teppei Sugo, a Japanese male born May 22, 2090 in Bunkyo-ku, Tokyo, stands 180 cm tall with a muscular build, weighing 68.8 kg. He possesses brown eyes and short black hair, often styled with gel and featuring two small bangs framing his forehead. His physical capabilities include running 50m in 6.50 seconds and eyesight of 2.0 in both eyes. He excels in karate and soccer, regularly engaging in muscle training and meditation during his spare time. As an Enforcer, his preferred attire is a black suit, white dress shirt, and tie, often worn under a green overcoat with black trim; his clothing frequently appears slightly oversized. Sugo attended Edogawa Municipal Daini Junior High School, graduating March 2107, followed by Tokyo Metropolitan Nakano High School's Faculty of Information Engineering, Major in Communication, graduating March 2111. He joined the Ministry of Defense in April 2111, assigned to the Navy Drones Unit of the National Borders Defense System. By November 2112, he transferred to the Drones Development Division. During his service, he obtained licenses including a Special Driving License for Large-sized Military Drones (October 2011), a Driving License for Special Large-sized Automobiles (January 2012), and an Officer of Security and Management of A-grade Gunpowder certification (March 2012). A pivotal event occurred during a 2112 military operation in Okinawa. Serving as a pilot providing air support, Sugo unknowingly followed orders to drop supplies containing VX gas, a chemical weapon that killed the entire ground squad, including his close friend and commander, Itsuki Otomo. This incident caused severe psychological distress, clouding his Psycho-Pass and leading to his resignation in May 2013. He was confined to the Adachi Municipal Psycho-Pass Correction and Medical Care Center until his release in November 2013. Sugo joined the Ministry of Welfare's Public Safety Bureau as an Enforcer in Division 02 of the Criminal Investigation Department in December 2013. He developed professional relationships with Inspector Risa Aoyanagi and Enforcer Tomomi Masaoka. Tragically, while responding to an incident at a Therapeutic Clinic, Sugo accidentally shot and killed Aoyanagi when he blindly targeted the individual with the highest Psycho-Pass. This event intensified his survivor's guilt and reinforced his self-sacrificial tendencies. He transferred to Division 01 in November 2014, redesignated as "Hound 3" after Sakuya Togane's death. His protective instincts manifested when he shielded Inspector Mizue Shisui and Enforcer Akira Yamatoya from an explosion, sustaining severe injuries. Gentle and soft-spoken, Sugo's personality is juxtaposed with unwavering duty and military discipline. He exhibits profound loyalty to colleagues, often prioritizing their safety over his own well-being, driven by guilt over the deaths of his military comrades and Aoyanagi. His military background endowed him with expertise in drone operations and tactical analysis, applied during investigations like the incident at a drone test site where Kirito Kamui executed a killing spree to collect Dominators. Collaborating with Nobuchika Ginoza during this event, Sugo later thanked him for saving his life from hacked drones. Their professional relationship evolved into mutual respect, particularly when Sugo used an Assault Dominator to neutralize Shisui after she endured multiple Dominator blasts, earning Ginoza's relief and trust. By 2118, Sugo transitioned to a Special Investigator role within the Foreign Affairs Operations Department's Suppressing Action Department at the Ministry of Foreign Affairs. In this capacity, he continued working alongside Ginoza, with both supporting and protecting each other during operations. Despite an offer to join the Ministry of Foreign Affairs promising greater freedom, he declined, opting to remain with the Public Safety Bureau as an Enforcer. Personally, Sugo maintains minimal connections outside work. His emergency contact is his elder sister, Masumi Sugo, residing at their familial address in Bunkyo-ku. He favors katsu-don but dislikes ikura-don. His room features a Japanese-style corner with tatami mats. He admires author Shiba Ryoutarou, particularly the book *Saka no Ue no Kumo* ("Clouds Over the Slope") due to his appreciation for the Akiyama brothers. His personal motto is "Indomitable perseverance," and he values sincerity in relationships, expressing a desire to be with someone who "will love him sincerely." A notable memory from Division 02 was a drinking contest with Enforcer Akira Yamatoya.
